Longbang Traffic Facilities with optional materials for overpass guardrails, suitable for urban expressways with impact resistance
Longbang Traffic Facilities with optional materials for overpass guardrails, suitable for urban expressways with impact resistance. Bridge guardrails need to balance anti-collision and line-of-sight transparency. W-beam steel guardrails buffer vehicle impacts through energy absorption and deformation. Hot-dip galvanized treatment can withstand the weather for more than 20 years. The height of the median guardrail is not less than 110 cm. The roadside guardrails are configured differently according to traffic flow to ensure the structural integrity under extreme conditions. The ecological river guardrail abandons traditional hard materials and uses a combined structure of living willow piles and wooden piles. The diameter of the willow piles is 10 - 15 cm. After being inserted into the river bank, they take root and sprout, forming a green barrier. The wooden piles are made of larch with anti-corrosion treatment, and willow branches are interspersed between the piles to form a fence. This kind of guardrail not only plays an isolation role, but also can fix the soil, protect the slope and purify the water quality. The willow roots can absorb nitrogen and phosphorus nutrients, reducing the risk of water eutrophication. The cost per meter is about 500 yuan, far lower than that of concrete guardrails, and the protection effect will be enhanced year by year as the trees grow. The disadvantage is that it takes 2 - 3 years to form a complete protection in the initial stage, and temporary barriers need to be supplemented during this period.

The folding angle of the zigzag guardrail is 150 - 170 degrees, and the radius at the turning point is not less than 300 mm. Each section is 3 - 6 meters long, continuously welded and then cut in sections. The color of the fluorocarbon spray changes with the light. The anti-collision calculation needs to consider the torque effect to strengthen the column section. As the core part of highway traffic safety facilities, the design of bridge guardrails not only needs to consider the anti-collision level and structural strength, but also needs to balance the line-of-sight transparency of driving and the comfort of driving psychology. Modern bridge guardrails mostly use W-beam steel guardrails or concrete composite structures, which can effectively buffer the vehicle impact through energy absorption and deformation, preventing out-of-control vehicles from rushing out of the road and causing secondary accidents. In terms of material selection, the hot-dip galvanized steel has excellent weather resistance, which can resist rain, snow erosion and ultraviolet aging, and has a service life of more than 20 years. At the same time, the height setting of bridge guardrails needs to meet the requirements of the "Design Specification for Highway Traffic Safety Facilities". Generally, the height of the median guardrail is not less than 110 cm, and the roadside guardrails are configured differently according to the bridge span and traffic flow to ensure the structural integrity under extreme conditions.
Longbang Traffic Facilities with optional materials for overpass guardrails, suitable for urban expressways with impact resistance. The riverside promenade guardrail has double handrails: the high one is 1.1 meters and the low one is 0.7 meters. The nylon-coated stainless steel has a warm touch. The spacing between the H-shaped steel columns is 2.5 meters. The tempered laminated glass panel is 10 + 1.52+10 mm, and there is a 20 cm green belt at the bottom. The mountain stream river guardrail needs to withstand the huge impact force during flash floods, and uses a gravity-type grouted block stone structure. The bottom width of the wall is 1.5 meters, the top width is 0.6 meters, and the height is 1.5 meters. The particle size of the block stones is 30 - 50 cm, and they are masonry with M10 cement mortar. A settlement joint is set every 2 meters, with a width of 2 cm filled with asphalt hemp. The top of the wall is poured with C25 reinforced concrete capping, with a thickness of 15 cm, and cast iron railing columns are pre-embedded. This kind of guardrail resists the flood thrust by its own weight, has good stability, but occupies a large area and has a long construction period. At the sharp bend and concave bank, the foundation of the wall is deepened to 1 meter below the scouring line, and large stones are thrown to prevent scouring.
