The beijing-shanghai high-speed railway station in nanjing steel structure subject entered into the phase of caps18 points and 11 o 'clock yesterday morning

The beijing-shanghai high-speed railway station in nanjing steel structure subject entered into the phase of caps18 points and 11 o 'clock yesterday morning, high-profile beijing-shanghai high-speed rail station of nanjing Steel structure workshop roof rack to slip for the first time. According to introducing, roof rack slippage practical equivalent of folk building & other On the beam & throughout; , this project started, marking the nanjing south railway station station main body structure construction officially entered the top stage.

Unit 11 pieces of rack & other Spell & throughout; Out of the station roof

Nanjing south railway station steel structure made by zhongjian industrial equipment installation co., LTD is responsible for the installation, the relevant person in charge of the company field introduced yesterday, nearly 110000 tons of total stationsteel structure engineeringWhen completed, the main Steel structure workshop station in the next key project is & other; Roofing & throughout; .

South railway station of the roof is made up of two layers inside and outside: the inner layer is network frame structure; Outer layer is including insulation and waterproof layer of roof panel. Rack installation project is equivalent to south railway station & other; Liang & throughout; , is the focus of the project and the difficulty.

Because of the large span roof space, the entire roof rack will be composed of 11 pieces of independent unit assembled, with a total area of nearly 100000 square meters, equivalent to 13 football fields. 11 piece rack unit total weight of more than 8000 tons, the largest area of about 12000 square meters, weighing about 1000 tons.

The modelling of the whole roof rack & other; Throughout middle & high, around the bottom; , peak height of 58.164 meters, the lowest was 41.2 meters, the north-south and east-west the maximum length of 451 m and 211 m respectively.

It is understood that such a large-scale, DaTiLiang high rack in the domestic rare, the sliding roof rack also is the present domestic high slip the project with the biggest span.

From south to north, 9 rack & other; Slip & throughout; More than three months

Reporters yesterday at the scene to see, with the beginning of the ceremony of the first piece of network frame while began to move, but slowly sliding speed of the human eye is almost feel not to come out. Personnel on-site engineering says, at the beginning of the project in terms of phase, the network frame of the sliding speed is only about 5 meters/hour, can reach 10 meters/hour, until mid slip of the entire project is expected to use more than three months time to finish.

In the nanjing south railway station, 11 piece of roof rack, except for north and south ends of two pieces of bulk ways, among 9 all adopt the slip from the south to the north to implement.

Every & other; Slip & throughout; Step, are made & other; Robot & throughout; Accurate measurement

Crossover operation throughout the south railway station engineering is more, in order to run out of space corresponding to other project, roof rack project was done in the air. After finish assemble in about 40 m high in the sky, again through the article about a total of 4 & other; The air track & throughout; 9 pieces slip to the location on the roof rack unit, finally together as the whole roof rack.

In the process of sliding, to avoid error, both sides keep synchronous orbit must go on. In order to ensure the accuracy and security, construction group to research and development of the digital hydraulic synchronous crawling robot, as propulsion system.

To develop accurate overhead rack slippage scheme, zhongjian installation after careful consultation with the owner, design unit, the scheme also passed a number of domestic leading experts in the collective.

9 all glide rack unit in place, the nanjing south railway station will be roof decoration and m&e installation
