Galvanized bridge guardrails, quality guaranteed, from the source factory, with novel styles. Longbang Traffic Facilities
Galvanized bridge guardrails, quality guaranteed, from the source factory, with novel styles. Longbang Traffic Facilities The music guardrail posts are embedded with resonance boxes. The tire vibration is converted into MIDI signals by sensors to drive the speakers. Each post corresponds to a note, and the vehicle speed determines the playing speed. The volume is controlled below 60 decibels to avoid disturbing residents. The pet guardrails for rivers are set in specific areas, with the height reduced to 0.8 meters, and crossbars are added at the bottom to prevent pets from getting out. The distance between the guardrail posts is reduced to 1 meter to increase stability. At the entrance, a pet waste bag dispenser and a trash can are set up to facilitate pet owners to clean up feces. The surface of the guardrail is painted with pet-friendly signs to guide citizens to walk their pets in a civilized manner. This user-friendly design is welcomed by pet owners, reducing the incidents of pets getting lost or falling into the water, and also avoiding the impact of pets defecating everywhere on environmental sanitation.
Galvanized bridge guardrails, quality guaranteed, from the source factory, with novel styles. Longbang Traffic Facilities The cable-anchored flexible protection system for cliff plank road guardrails. The main cable wire rope has a diameter of 22 mm and a breaking tension of 350 kN, and is anchored in the rock mass. The secondary cables are spaced 1 meter apart and have a diameter of 16 mm, forming a net. The height is adjusted according to the terrain to ensure the safety of tourists. The Chinese-style garden landscape guardrails pay attention to the combination of virtual and real and the creation of artistic conception, and commonly use ice crack or a Chinese character-shaped pattern for hollowing out. The precast concrete components are made of GRC material, formed by mold pressing, with a pattern fineness of up to the millimeter level. The component size is 60×60 cm, with a thickness of 5 cm, and the surface is sprayed with antique copper paint. The posts are finished with stone-like paint to match the architectural style. The guardrail is 1.2 meters high, and a palace lantern-shaped garden light is set every 3 meters. At night, after being lit, the light and shadow are projected on the ground through the hollowed-out pattern, forming a wonderful light and shadow effect.
Galvanized bridge guardrails, quality guaranteed, from the source factory, with novel styles. Longbang Traffic Facilities The river ice protection guardrail has a triangular cross-section with the sharp corner facing the water flow direction to break up the ice. The H-shaped steel posts are spaced 1 meter apart. In the sections with severe ice, ice-breaking cones 2 meters high are added at intervals of 2 meters, and buffer springs are used to absorb the impact energy. An inspection is carried out every spring. The ecological river guardrail abandons traditional hard materials and adopts a combined structure of living willow piles and wooden row piles. The willow piles have a diameter of 10 - 15 cm and will take root and sprout after being inserted into the river bank, forming a green barrier. The wooden row piles are made of larch after anti-corrosion treatment, and willow branches are interspersed between the piles to form a fence. This 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 in the initial stage to form a complete protection, and temporary fences need to be supplemented during this period.
