Longbang Traffic Facilities, a physical factory for non-standard viaduct safety guardrails with a long service life.
Longbang Traffic Facilities, a physical factory for non-standard viaduct safety guardrails with a long service life. The modern and simple stainless - steel square tube guardrail is 30×30 mm in size, with a wall thickness of 2 mm, and has a brushed finish. The spacing is 15 cm, and it is semi - transparent. The columns are hidden in the green belt with the bottom 10 cm off the ground to create a floating feeling. It costs about 800 yuan per meter and is suitable for modern squares. The bridge guardrails in ice - prone areas need to be equipped with ice - melting and snow - removing functions. The built - in carbon fiber heating cable has a power density of up to 300 watts per square meter, which can maintain the surface temperature of the guardrails above 5 degrees Celsius in an environment of minus 30 degrees Celsius. The control system automatically starts and stops according to the data from meteorological sensors, and the energy consumption is 25% lower than that of traditional electric tracing. The surface of the guardrails is sprayed with a super - hydrophobic coating, with a contact angle greater than 150 degrees and an ice adhesion strength of less than 0.1 MPa. The ice can fall off with a slight vibration. In terms of structural design, anti - uplift piles are added at the bottom of the guardrail columns to prevent frost heave damage, and the pile length extends 1 meter below the frozen soil layer. In addition, the guardrail cross - beams use an open - section design to facilitate the natural sliding of snow and avoid deformation caused by overload due to snow accumulation.
Longbang Traffic Facilities, a physical factory for non-standard viaduct safety guardrails with a long service life. The urban viaduct guardrails use aluminum alloy hollow carvings combined with LED light strips, which not only ensure safety but also enhance the recognition of the skyline. Engineers optimize the column spacing through finite element analysis to control the deformation of the guardrails within 50 cm after being impacted by an 80 - ton heavy vehicle. A slidable structure is adopted at the expansion joints to avoid temperature stress. The guardrails along mountain streams and rivers need to withstand the huge impact force during flash floods. They use a gravity - type grouted rubble structure, with a bottom width of 1.5 meters, a top width of 0.6 meters, and a height of 1.5 meters. The rubble has a particle size of 30 - 50 cm and is masonry with M10 cement mortar. A settlement joint with a width of 2 cm filled with asphalt hemp is set every 2 meters. The top of the wall is poured with a C25 reinforced concrete coping with a thickness of 15 cm, and cast - iron railing columns are pre - embedded. This kind of guardrail relies on its own weight to resist the flood thrust, has good stability, but occupies a large area and has a long construction period. At sharp bends and concave banks, the wall foundation is deepened to 1 meter below the scouring line, and large - sized stones are thrown to prevent scouring.
Longbang Traffic Facilities, a physical factory for non-standard viaduct safety guardrails with a long service life. The floating steel anti - collision box for river anti - ship - collision guardrails is 3×1.5×1 meters in size and filled with closed - cell foam. The steel plate is 6 mm thick. The red - and - white warning paint is connected to the river - bottom anchor through a chain. The deformation of the box absorbs energy to protect the bridge piers. The self - repairing bridge guardrail adds a microbial mineralizer to the concrete. When cracks appear, bacteria metabolize to produce calcium carbonate crystals to fill the cracks. Cracks within 0.5 mm in width can be completely healed within 28 days, and the strength after repair can recover to 85% of the original strength. The microorganisms can survive in the dormant period for up to 200 years, which is suitable for the 100 - year design life of bridges. This technology greatly reduces the frequency of crack repair and reduces the full - life - cycle maintenance cost by about 40%. It is currently in the pilot stage before large - scale promotion and is expected to become the standard configuration in the industry within five years.
