Our main products: pot bearings, rubber bearings, bridge expansion joints, rubber water stop, rubber dam, waterproof board, drainage board, geotextiles, geogrids, high-speed guardrail, tunnel fire retardant paint, and high-speed Fence other rubber products. Widely used in railway bridges, roads and bridges projects, tunnels and subway project; water conservancy, power generation and sewage treatment works. Mainly used in railway bridges and drainage, highway guardrails on both sides of the bridge support and engineering and chemical sewage systems. 1. The vent pipe construction design requirements should be implemented, vent pipes protruding bottom surface of the structure should not be less than 30mm, longitudinally spaced not more than 4m. 2. overpasses and bridges on the highway, vent pipes should not be directly linked to the lower plate, the vent pipe can lead directly to the ground through the longitudinal and vertical drains. 2 Features a drainage Safety: orifice located in valleys, peaks and filter fabric due to a two-way effect, orifice clogging, to ensure the smooth flow of permeable system. Second, the combination of strength and pliable: a unique double corrugated structure effectively improves the external pressure strength of the product, the drainage system will not be affected by outside pressure deformation drainage effect. Third, the economy: the same caliber compared to other drains, its price is lower. 3. Uses 1. highway retaining wall on the back and ditches various vertical and horizontal drainage; 2. tunnel underpass of drainage; 3. municipal engineering, water purification plants, sewage plants, landfills and other drainage; 4. 5. The development of hillside slope soil and water conservation;; drainage golf courses, sports fields, parks and other green spaces of underground 6. Xiuxie site preparation works of drainage;
