Highway guardrail role and design condition of highway guardrail out outside

Highway guardrail role and design condition of highway guardrail out outside to prevent runaway vehicle collision obstacles or other facilities outside the road, rushing or median into lane to cause more traffic accidents, but also can make the vehicles returned to normal driving direction, the damage of the smallest, and need to be able to have the effect of inducing the line of sight. Highway guardrail generally divided into flexible guardrail, mesh fence and flexible rigid guardrail guardrail generally refers to the cable guardrail, rigid guardrail generally refers to the cement concrete guardrail, semi-rigid guardrail generally refers to the beam guardrail. Beam guardrail is one of the pillar with a fixed beam structure, rely on the guardrail of the bending deformation and tension resistance of vehicle collision, beam guardrail has certain rigidity and toughness. Through beam deformation to absorb impact energy, its easy to replace damaged parts, has a certain view entrainment, can be coordinated with road alignment, beautiful shape, the wave beam guardrail is applied most widely at home and abroad recently. Raw material: gb q195, low carbon steel plate, etc.; After surface processing methods: extrusion jinsu; After yi ke electric galvanized/hot dip galvanized steel plate stamping forming jinsu or coating; Low carbon steel board after dipping plastic extrusion; Low carbon steel board after extrusion galvanized + jinsu/coating; Jinsu materials for (pvc& PE); Application: highway, large parking lot security collision; Product features: bending which increase the beautiful sex, at the same time increase the intensity of mesh, have it both ways; Automatic production line, extrusion, surface clean without damage, anticorrosion sex is extremely strong; Surface treatment way of mature; Pe& PVC material is non-toxic harmless, anticorrosive, prevent aging, sun resistance, resistance to high and low temperature characteristics of outdoor environment in the service life can reach 10-20 years; Product structure concise, beautiful and practical, easy to transport, installation, good anti-theft performance, restricted by the actual terrain is small, the mountain, slope, bending area adaptability strong, moderate cost, suitable for widespread use. Highway crash barrier is one of the most important transportation infrastructure, the highway in our country developed from the 80 s, it to national economy and social development plays an important role. Highway is important to maintain facilities and security. Highway crash barrier is a typical cold-formed section steel products, the specification is 4320 * 310 * 3 company imported American R425 mill strip automatic leveling, precision punching, feeding slow lane 18 roll forming, scale cutting and other advanced computer technology conditions, maximum limit guaranteed the collisionGuardrail plateThe shape of a size and linear degree. The section size completely meet YB4081-92 standard requirements. Product use: widely used in highway. Material: stainless steel metal of high strengthGuardrail plateTechnical field: guardrail plate, the utility model is mainly used for highway lane segmentation protection. Technical background: now the guardrail board usually is made of galvanized steel plate, the resulting problems include: 1, the steel plate is easy to oxidize, 2, easy to scratch, 3, the production cost is higher, 4 guardrail, the impact of the lighter, easy to cause deformation, 5, and the production process easy to produce pollution. The utility model to solve the technical problem is to overcome the shortcoming of existing technology, and provides a good impact resistance, low cost, long service life, higher security, green environmental protection and good use effect highway guardrail board. Barrier to solve the technical problems of this practical new type is adopted by the technical scheme: the guardrail plate whose character is body adopts high molecular weight of PVC material, during production without corrosion protection, coating processing, truly green, environmental protection, at the same time because the PVC material cost is much lower than steel, the comprehensive cost is low; The guardrail plate mechanical structure is M shape, set up in the board have and exhibition along the direction parallel to strengthen hole plate body, strengthen the hole thermal coated glass fiber as reinforcement, at the same time in the upper plate bodies to strengthen impact strength, the convex set are two rows of holes and reinforcement. A new anti-collision guardrail, mesh fence www.jtwiremesh.com with existing techniques, with good impact resistance, low cost, long service life, higher safety and green environmental protection advantages, such as column board width 310 mm, thickness: 3 mm, 4 mm. 1 t fence panels can be spread: 3 mm thickness of 80 m, 4 mm thick 61 meters. 3 mm thick heavy 12.3 tons per kilometer, 4 mm thick heavy 16.388 tons. Columns: roughness specifications Q114, Q140MM length according to requirement of 1.85 m, 1.95 m, 2 m, 2.15 m, 2.27 m, 4.5 MM thick. 3, with $250 per kilometer barrier plate. Column spacing of 4 meters, with 250 per kilometer, the columns, the end of 2, 250 cap, screw 250 sets, 250 bracket, control block 250.

Urban traffic barrier of development will be less and less
