Drain main functions: a guide water drainage: drainage water protection board in a prominent circular flat Taichung empty structure, capped with geonet, geotextile form a sandwich drainage space, rainwater drainage into the interlayer space from geotextile rapid discharge, greatly eliminate hydrostatic water phenomenon waterproof layer, the active principle of water can be achieved through the initiative waterproof effect. 2, waterproof performance: HDPE drainage water protection board material itself is a good waterproof material, through a reliable way of welding or bonding, so the drainage water board into a good secondary waterproof material. 3, protective performance: HDPE drainage water protection board material with high toughness and tensile strength, corrosion resistance, effectively protect buildings and waterproof layer, and resistance to various types of soil pH and plant thorn in the basement wall When the backfill, the protection of buildings and waterproof layer from damage. Schomburg up drain works: drainage board flapper machine insert soft ground, in the upper part of preloading loads, soft ground in pore water discharged by the drainage board level upper bedding sand or plastic pipes, and by Other local exhaust to accelerate the consolidation of soft foundation. In soft soil treatment, the role of the drainage board design, construction equipment basically the same bag sand well. Drainage Board Application: domestic and international highways, railways, airports, power plants, yards, ports, land reclamation, sewage treatment plants, landfills, land reclamation, water conservancy and hydropower, port construction and other projects in the soft ground treatment project.
