From platform line 14 layer west end came down to no. 10 line; From no. 10 line platform layer to the underground station hall on the first layer, layer down to the line 14 platform.
Fengtai station connecting railway station station hall two times the normal size of stand
Opens a subway station is located in fengtai fengtai south railway station, subway fengtai station north hall and the railway station underground hall connected underground station. South station near residential areas, extend inward and outward to the outside community.
The zero transfer scheme is different from the south railway station, the station is not located in the core region of railway station, but on the main square on the outside of house, and the south area is adjacent to the railway station, mainly consider the appropriate transfer distance between, can avoid the impact of the change to the passenger flow of subway rail, to ensure the safety of subway operation, at the same time solve the problem of the railway, the subway passengers transfer to.
And ground transfer form is different with Beijing station, Beijing station has opened the transfer distance, but need to convert from the ground, increase the space distance.
Into the line 10 fengtai station, tall and spacious space is surprising.
& other; Platform height 8.5 meters, stands 8.9 meters high hall, with a total area of 26000 square meters, is a common station twice the scale of construction. Throughout the &; Beijing urban construction groupThe constructionChief says, this is mainly think about the future of fengtai fengtai station subway and high-speed railway station transfer to bring huge passenger flow.
Even after decorate condole top, fengtai station platform space is still close to 6 meters high, large red pillar and & other Scratchable latex & throughout; White sunk panel design decoration to make the entire station look very solemn, style and fengtai railway station square founder of tall buildings in the Steel Structure Project http://www.jingtabuilding.com/ts.html.
The north-south station, the future will dock with the fengtai railway station underground transfer hall directly, the subway station northwest station hall wall is dismantled and underground channel entrance into the railway station. Passengers from high-speed rail in the subway, however, is relatively simple, and from metro transfer high iron law also need transfer from underground station entrance hall to the ground.

A CZ3633 flight cancellations notice posted on the wall
A CZ3633 flight cancellations notice posted on the wall. This is January 1, 2013, on Tuesday. Near dusk, hunan zhijiang airport terminal unusually quiet, reporters ready take the plane to fly to Beijing at 8 in the evening, can not attend.
& other; I don't know what reason to cancel the flight, this kind of thing often in the past. Throughout the &; A Steel Structure Project http://www.jingtabuilding.com/ts.html play a ball game to the young people at the airport.
A flight to Beijing is every Tuesday, four, six, in order to move on, reporters have to in the second day came to changsha from zhijiang, due to the high iron, missed the night in changsha for one night, the third genius back to Beijing.
Zhijiang airport and huaihua zhijiang county, adjacent to walk half an hour. Now a quiet airport, not in 70 years ago.
In 1937 after the outbreak of the Anti-Japanese War, the kuomintang (KMT), in order to prevention, use of migrant workers since 1938, 200000, near the zhijiang county, hunan province began building the airport. With the victory of war of resistance against Japanese aggression in 1945, the airport get idle until 2003 reconstruction, in December 2005, formal shipping again. And because the traffic is too little, so far the airport is in loss.
Li xiaojin, a professor at the university of China civil aviation that airport generally has two kinds of corporate profitability and public welfare characteristics, zhijiang airport should be a more prominent public welfare. To increase the tourists, but the airport core is to develop economy as soon as possible, average per capita income increased by 1%, with the local passenger increase is 1.5%.
From busy to idle
Hunan ZhiJiangXian zhi jiang town seven Bridges in the village the villagers Yang Muzhen this year at the age of 75. He told reporters, was to build airports spent a lot of cost.
& other; When several storeys high, big blind-folded a blind-folded for thousands of people, is good to level off the runway. Stones are built airport pick to 3 kilometers place, so far, many migrant workers toil and died. Throughout the &; Yang Muzhen said.
The airport was built in 1942, the Soviet air force and chennault and the organization of the American volunteer group & other; The flying tigers & throughout; In, when most of the time the airport parked more than 500 combat aircraft, airports have occurred over the guild wars, the airport has allied & other; Throughout the far east, the second largest airport &; Be produced.
Since 1938, from zhijiang airport aircraft of China and the United States to the Japanese with a heavy blow. On February 25, 1945, from the airport bomber, bombed Tokyo directly. For the Japanese launched in April 1945 the xiangxi battle for zhijiang airport (also known as zhi jiang battle), finally in June 7, 1945, to end at the expense of the Japanese army was annihilated 28320 people. On August 21, 1945, zhijiang surrender ceremony held on behalf of the Chinese Anti-Japanese War victory, the Japanese surrendered in China force deployment diagram.
When combat stress, there are theory is that every minute a plane, and this is a better than how busy the Beijing capital airport. When combat zhijiang airport where the single combat tens of thousands of players. Whole new in zhijiang into several ten thousand people of the migrant population.
In 1949, the kuomintang (KMT), the air force after withdrawal, zhijiang airport have been idle, full of weeds, and other Local farmers to plant in the past, but can't get into, people watch, also don't let grow. Throughout the &; Yang Muzhen said.
Airports reopen reconstruction in 2003, to December 2005 formally.
But so far the airport is still limited usage. Reconstruction in 2003, for example, the airportdesignthestandardIs 2010 years, throughput of 200000 passengers. Only 93851 to 2012 passengers, less than half in 2010 is expected to target. Interestingly, zhijiang airport on December 12, 2012, started the expansion project, is expected to realize annual passenger throughput in 2020 2020 goals.
So far, zhijiang airport is still in heavy losses.
Waiting for the economic take-off
Zhijiang airport to reproduce the past glory, need is the xiangxi, especially kafoul's rapid economic development.
Business hotel, mongkok, hunan ZhiJiangXian old his learning xi, 60, has his own opinion.
, he points out, the past zhijiang airport as the far east, the second largest airport, the kuomintang (KMT) relating to a large number of VIP in zhijiang, the number may be on hundreds and after the Anti-Japanese War, large Numbers of people to evacuate, the local population is little, also abandoned at the airport.
When airport 5 kilometers long from east (5000 meters), north and south long 3 km (3000 meters). To the restoration and reconstruction since the airport is only 20%. Most did not put into use. Even now the expansion, in fact, most still use.
According to understand, zhijiang airport built into use again in 2005, the airport design size for the 3 c level, which can provide Boeing 737-300 aircraft (140 seats). The runway length 2000 meters, 45 meters wide. Design of tourist reception capacity is 200000.
Now the airport has implemented a new expansion, prepare to extend existing runway 600 meters, the construction of a new vertical contact way connected to the runway, the expansion of the station area of about 16565 square meters, the expansion of the new terminal building 3600 square meters, parking lot 1580 square meters, total investment 424 million yuan. The airport ready to 4 c level. Can handle is expected to medium-sized passenger aircraft airbus A320 and Boeing 737. Design reception capacity of 400000 passengers.
Zhijiang airport general manager Long Yue explanation, greatly improve the reception ability, the main reason is that in order to meet the needs of airlines.
By the serious loss in airport, state subsidies have only 3.13 million in 2013. And hunan airport construction group to the airport before, huaihua city government subsidies on airlines, there are more than 1000.
The core problem or didn't do a good job in tourism. & other; Zhijiang high-speed rail to high-speed rail to high-speed high-speed, at present there are shanghai-kunming high-speed, zhijiang shanghai-kunming high-speed rail pass, zhijiang airport, but zhijiang is difficult to grow, and this is not good with local tourism and industrial enterprises. Throughout the &;
Zhijiang no industry, less tourists. 2012 zhijiang county had received 2.76 million tourists from home and a 8.5% increase from the previous year. Tourism industry revenue reached 932 million yuan, an increase of 9.3%. But with zhijiang distance more than 50 kilometers of xiangxi phoenix, tourists nearly 7 million person-time. Click here to view, zhijiang tourism is very lag.
Zhijiang airport has noticed the tourists, the phoenix phoenix tourists because want to fly, only near tongren and zhijiang airport at the airport. Tongren airport throughput of 81000 visitors in 2012 person-time, not more than 90000 people as zhijiang airport.
On December 23, 2012, the ZhiJiangXian opening zhi jiang to phoenix in the bus, but there are only a few from phoenix to zhijiang by plane, finally had to cancel.
Cheng Xuexi thinks, zhijiang to development, the key is to have a long term.
Li xiaojin, a professor at the university of China civil aviation that more than 100000 people in the airport passenger throughput, survival is no problem at the airport. If throughput reach 1 million, you can make money. As a Steel Structure Project, zhijiang airport public welfare still lay particular stress on at present. & other; After all, when you don't convenient rail and road, the civil aviation can play a leading role. To airport passengers increased significantly, is still subject to the local economic development. Throughout the &;

in recent years, around the subway construction under the background of high-speed growth
Summary: in recent years, around the subway construction under the background of high-speed growth, the subway construction accidents are increasing, the cause of the accident, the most landslides is appeared in the process of the construction site, Shanghai, Beijing, xian, hangzhou and other places have happened this kind of accident. Steel Structure Warehouse, lower cost,managementIs not caused by the subwayThe constructionThe main reason of the accident. Wang ever processing of hangzhou subway accident, his reason for subway accident took four conclusion: unreasonable unreasonable schedule, reasonable cost, unreasonable contract, reasonable solutions.
Killed 5 people of xi 'an third line collapse accident, safety issues for the construction of the subway back on to the people's horizons.
Official identified as the cause of the accident was in xian & other; Shield tunnel structure instability throughout the &; , let the claim many times to participate in xi 'an subway demonstration project of Chinese academy of engineering academician wang felt a little confused.
On May 7, he said in an interview, & other; Shield is the most should not be a problem, it is a very mature model, even if a problem also has a set of protection system of shield construction, not easily the dead. Throughout the &; Wang believes that main causes of the subway construction safety accident appear & other; Catch time, price and poor management & throughout; .
For the above statement, the relevant administrative department of the exact word, but it is worth noting that not completely according to the daily economic news "reporterstatisticsAre construction of metro lines, the current national more than 70, a total investment of more than 8000 one hundred million yuan, if plus has been approved by the project, investment of 1.5 trillion yuan of above.
Shield construction generally will not cause casualties
Xi 'an metro line three safety without accidents timing card at the 477th heaven, and stop this number the reason & other; Shield & throughout; The problem.
There are some strange name, but this is one of commonly used method is to build the subway. Shield shield construction is the use of excavators in underground excavation, soft foundation excavation surface to prevent the collapse or maintain stability of excavation face at the same time, the machine safely inside the tunnel excavation and lining operations. Generally speaking, the shield tunnel boring machine cutting soil excavation, transport soil crusts, tunnel lining, measure orientation deviation, and other functions.
Wang are familiar with this kind of machine, he said, this is a cylinder shell that shield components, there are a variety of operating systems, sells more than 4000 4000 yuan, and other Shield technology is very mature, and has a safe mode of operation, not the need of personnel, even happen collapse, shield outside dish support not to live but internal support system, general won't appear in death. Throughout the &;
But in recent years, shield tunnel construction accidents occur frequently. At 5 am on May 6, 2011, tianjin metro line 2 last shield interval had been excavating, sudden accident, resulting in two sinking of shield machine, two-way tunnel scrap, but caused no casualties.
Wang, nanjing subway shield construction method is used to build, repair to the xuanwu period of mechanical annihilation phenomenon also happen, but the shield protection system, so accidents didn't kill anyone, & other; Shield method is to build the subway very safe. Throughout the &;
Based on xi 'an metro construction headquarters, deputy commander in chief Qiao Zheng is introduced, the exact location of the collapse accident is within the range of xi 'an metro line no. 3 DE gruyter temple one of shield starting shaft. On the north side of the shaft has two underground running tunnel, underground running tunnel of the left line to 8 m, its founder constantly in the process of the layered soil, collapse accident occurred.
, according to a railway engineering in the industry of shield construction process need to be at one end of the tunnel for a shaft or pit, hanging into the installation of shield machine, the shield machine starting shaft or hole the wall of the foundation pit excavation, alongdesignHole line forward until she reached another shaft in the hole line or to the end of tunnel. The researchers speculate that may be the problem in shaft.
In addition to shield tunnel structure instability, & other; Rain lead to loose soil & throughout; Has been officially listed as one of the reasons. However, a citizen, told reporters that xi 'an this a few world rain without an umbrella, did not even wet road.
Wang has repeatedly invited to xi 'an subway's argument, he said: & other; Xi 'an itself is the loess, the soil is suitable for building the subway, I don't have to completely when the argument put forward in some places the shield method is adopted, because of shield method is suitable for in humid areas, and xi 'an construction by shield method to add water, if the water is too much loess will form a cohesive soil affect machine operation, can use commonly used in Beijing subway & lsquo; Shallow depth WaFa & rsquo; Throughout the &; .
The accident on shield construction problems, and loss of life, this let wang has some regret, he said & other; Don't know what is the problem & throughout; .
& other; Rob throughout time pressure & cost; The cause or accident
In fact, this is not in xi 'an subway first collapse accident. On August 2, 2009, sprinkle jinqiao station of xi 'an subway construction site collapsed slump have happened accidents, killing 2 homework personnel.
In recent years, in the subway construction under the background of high-speed growth, the subway construction accidents are increasing, the cause of the accident, the most landslides is appeared in the process of the construction site, Shanghai, Beijing, xian, hangzhou and other places have happened this kind of accident.
On December 31, 2012, Shanghai metro line 12 in pudong jinqiao parking lot access library construction collapsed, killing five people. On November 15, 2008, hangzhou customs avenue subway construction site, large area ground subsidence accident killed 21 people.
According to incomplete statistics, at present the country is on the construction of metro lines more than 70, a total investment of more than 8000 one hundred million yuan, if plus has been approved by the project, investment of 1.5 trillion yuan of above. To build metro cities are also growing, wang, new construction is 28 cities last year, behind a batch of the four cities, this move GongJian metro city up to 32.
First planning approval again has become the norm in local subway investment, and even some cities had started too late approval. The accident of xi 'an metro line 3 a project about the alleged & other; Built before shipment & throughout; , the first phase of the line in May 2012 to obtain the approval from the national development and reform commission (NDRC), but a number of projects, including the above bid accident already & other; Construction & throughout; Or & other; Comprehensive construction & throughout; .
Notable is, in the process, the project investment cost is high, the construction cycle is long, weak profitability, and other issues also emerge. Underground of high investment, let the local government is facingfinancingressure, and to build the subway, let local government with greater debt burden. According to metro industry insiders revealed that in the current mode of subway construction, the investment proportion of local government is likely to be accounted for by more than 40%, while the other is by the subway company loans. Under the subway widespread losses, & have sprung up all other In order to to raise iron & throughout; Model, but it's still not enough to solvefinancingThe problem.
& other; Rob period, lower cost, poor management is the main cause of subway construction accident. Throughout the &; Wang ever processing of hangzhou subway accident, his reason for subway accident took four conclusion: unreasonable unreasonable schedule, reasonable cost, unreasonable contract, reasonable solutions.
In addition, different subway lines in the same city, there are multiple units. Such as the construction of the engineering of xi 'an subway accident ZhuZong group in Beijing, and in 2009, construction of the line for the iron 2 bureaus co., LTD., another supervision party supervision company for the Beijing subway.
& other; Some of the construction unit to take the subway is not experienced. Throughout the &; Wang thinks, at present more and more city subways is shenzhen BT construction model, entirely by the big oneConstruction enterpriseTo pay for,standardAnd solutions are completely good, be decided by the company owner party pay,Construction enterpriseBuild the subway to the owner after.
It is understood that the so-called meaning & other BT mode; Construction - transfer & throughout; , is the government using private money for non-business infrastructure projects of a financing mode, refers to the operation of a project by project general contracting company, Steel Structure Warehouse, construction acceptance back to the owner, the owner pay to investors in the project total investment plus a reasonable return process.

Problems and countermeasures of construction steel structure
Problems and countermeasures of construction steel structure industry Steel Sheds http://www.jingtabuilding.com/steel-sheds.html disgn And drawing applications abroad more static strong plasticity analysis is rarely used.
Light steel structure is mainly refers to the palisade structure of gantry light sheetsteel frameLight house structure (hereinafter referred to as "light steel") and the pressed steel sheet roof arch shell, it is of the fastest developing all kinds of steel structure in China in recent years. Light steel structure plant on the number and size has a larger development. This reserve is characteristic of two kinds of structure bearing capacity is low, especially the arched roof half-and-half across the snow load is very sensitive. In recent years, there have been some accident, have a plenty of churning out, have a plenty of collapse in the construction.
Spatial structure mainly USES the rack (geodesic), in addition to cable membrane structure, network structure and other hybrid structure. Rack is widely used in our country, the new trend is to increase in the number of network frame with rectangular steel bar; In recent years, widely used in the terminal space truss, the bar adopts the round steel tube, chord with curved shape; Arch structure and the emergence of caused the people's interests, but it remains to be further discussed the performance and application of scale.
Multi-storey steel structure house beautiful appearance, interior space is large, short time limit, the seismic performance is good, benefits a lot. Development of multi-storey building will open up new areas of construction steel structure, to the industry development bring new opportunities, should as a focal point of recent to accelerate development. Development of multi-storey building should be to locate it at a reasonable cost, and can't ask it like a brick structure of the cost. To prevent churn out on quality, so as not to damage the image of multi-storey building. The development condition, multi-storey steel structure building has should actively promote and promote its rapid development.
Hindering the development of the steel structure industry booming, and the industry as a whole management planning. Must accelerate industry development information network is established. Industry association has been established for many years, because the number is much, various types of structure, development is rapid, industry has yet to establish and improve the statistical work. It is unable to accurately grasp the development of industry, including the countrySteel structure enterpriseNumber and size of the total, all kinds of steel structure building (such as gross tonnage and a building area of the exact number, unable to provide the basis for government decision-making. Steel structure of China construction metal structure association committee of China steel structure association and have done a lot of work in this respect, should speed up the pace in the future, strengthen the establishment of information network and perfect, make it play a bigger role.
Design for light steel enterprise qualification evaluation is an important content of business management, also is enterprise's urgent desire. Plans to start from the steel structure factory of light steel design qualification, under the leadership of the competent department of the ministry of construction, steel structure of China construction metal structure association committee according to the entrusted, assist with the job, and not regulate the behavior of enterprises and market to clean up.
In addition to speed up the design review system is established. When using the steel structure of large public buildings, it is technically feasible, in relation to the safety of the public and the investment is reasonable, social influence is very big. Look from the current situation, the structure scheme is reasonable, organize experts to review is very necessary. Competent authorities shall according to the project scale, build system of hierarchical management as soon as possible, to establish design review expert database, from the source to control, reduce blindness, improve the scientific nature, prompt healthy development of the Steel Sheds industry.
