Galvanized and plastic-sprayed bridge anti-collision barriers with impact resistance for urban expressways, Longbang Traffic Facilities
Galvanized and plastic-sprayed bridge anti-collision barriers with impact resistance for urban expressways, Longbang Traffic Facilities. Anti-glare barriers are specially used for highway median strips, with a steel plate punched louver structure. The shading angle is 30 degrees to block the light of oncoming vehicles. The height is 1 meter with galvanized treatment to ensure night driving safety. River ice protection barriers are installed in cold northern regions. They use steel barriers with a triangular cross-section, with the sharp corner facing the water flow direction to break up ice floes and reduce the impact force. The height of the barrier is 1.5 meters, and the spacing between columns is 1 meter, using an H-shaped steel cross-section. In river sections with severe ice conditions, ice-breaking cones are added in front of the barriers. The height of the cones is 2 meters, and they are arranged at intervals of 2 meters. Buffer springs are installed between the ice-breaking cones and the barriers to absorb the impact energy of ice floes. Check the barriers for frost heave and deformation before the beginning of spring every year, and repair damaged parts in time. This kind of barrier can effectively protect the safety of downstream bridges and dams.

In severe ice sections, ice-breaking cones with a height of 2 meters are added at intervals of 2 meters. Buffer springs absorb the impact energy. Check them every spring.
The shared pedestrian and non-motor vehicle barriers on municipal bridges need to balance the passage needs of pedestrians and non-motor vehicles. Usually, a three-beam structure is adopted. The bottom beam is 30 centimeters from the ground to prevent bicycle wheels from getting stuck. The middle beam is at a height of 60 centimeters for people to lean on when pushing a bicycle. The top beam is 1.1 meters high to ensure pedestrian safety. The barrier columns adopt a variable cross-section design, with the bottom width of 12 centimeters gradually tapering up to 8 centimeters, which not only saves materials but also enhances the sense of stability. In the bus stop area, the barrier protrudes outward by 1.5 meters to form a bay-style parking space. The protruding section of the barrier is changed to an openable type for the convenience of buses to enter the station temporarily. All corners are polished into a R20-millimeter rounded corner to prevent sharp edges from scratching pedestrians' clothes or vehicles.
Galvanized and plastic-sprayed bridge anti-collision barriers with impact resistance for urban expressways, Longbang Traffic Facilities. Bridge barriers need to balance collision prevention and visual transparency. Corrugated beam steel barriers buffer the vehicle impact through energy absorption and deformation. The hot-dip galvanizing treatment can withstand the weather for more than 20 years. The height of the median strip barrier is not less than 110 centimeters. The roadside barriers are differentially configured according to the traffic flow to ensure the structural integrity under extreme working conditions. The river barriers beside the ancient city wall ruins need to be coordinated with the style of the city wall. They use terracotta railings in the color of city bricks, with the surface being aged to imitate the texture of the ancient city wall. The terracotta railings are fired at a temperature of 1200 degrees Celsius, with a compressive strength of 50 MPa and a water absorption rate of ≤8%. The railing shape imitates the stone railings of the Ming Dynasty, with scroll grass patterns carved on the balustrade panels and lotus seats on the top of the balusters. During installation, the traditional mortise and tenon structure is adopted, and tung oil mortar is used for caulking. The foundation of the barrier is hidden underground to avoid damaging the ruins' style. Each terracotta railing has an antique mark, blending in with the ancient city wall.
