Soft water pipe with a new pipe inverted filter through the water (row) role to overcome the many ills of other drainage pipe, because of its unique product design principles and the excellent performance of the constituent material, row, seepage effect , the use of "capillary" phenomenon and "siphon" principle, set-absorbent, permeable, drainage wrapped meet the engineering requirements for pressure capacity and water permeability and filtration role. Temperature changes due to geological and geographical break, and can achieve the effect of the discharge of clean water will not cause secondary pollution to the environment, is a new type of environmentally friendly products. Because of its simple construction, no joints, no special requirements on the geology, topography, dark drainage may want to use. Soft water pipe in a rust-proof coil support tube to form a high compressive soft structure, non-woven fabric lined with filter, sediment impurities can not enter the tube, thus net seepage. Polyester yarn around the well-being of cladding has excellent water absorption, quickly collect the excess moisture in the soil. Wall covering layer of rubber ribs and spring steel tubular body become organic integrally, having good all-round water-permeable, water permeate smoothly infiltrated into the pipe, while the sediment impurities are blocked outside the tube, so as to achieve the water-permeable, filtration, drainage coherent purposes. Soft water pipe product characteristics: (1) high carbon steel wire: phosphoric acid rust treatment and covered with PVC to prevent acid corrosion, steel wire spiral skeleton to ensure that the wall surface is flat and pressure. ⑵ non-woven filter layer: ensure effective filter to prevent sediment from entering the tube. (3) synthetic polyester fiber: the warp yarns coated with PVC the high strength Tetoron yarn or nylon yarn, weft use a special fiber to form sufficient tensile strength. Waterproof dam, protection slope and other projects on the one hand by the impact of the water within the dike (slope) precipitation, infiltration, on the other hand by the dike (slope) surface precipitation, causing dams, soil protection slope bearer adhesion reducing capacity and soil, the dead weight of the dike (slope) gradually increased extrusion of water and water base, a long period of time inside the dike (slope), large pore in a certain direction, and gradually increased with the aperture Finally, caused collapse bursts, the piping phenomenon which is often said. The non-woven artificial soft water pipe will completely solve this problem. Weight within the dike (slope) and the basis of internal water in the soil layer under greater pressure to enter the soft water pipe leading away dike (slope), so that the internal pore pressure reduction, can be a long time to keep the soil internal inherent structure, increase the stability of the dike (slope). Has: 1) pore diameter is small, full-permeable, the permeability; 2) compressive resistance high tensile strength, long life; 3) corrosion-resistant and anti-microbial aggressive; 4) overall continuity, joint less convergence; 5) light weight, convenient construction; 6) soft, good and soil combined with the advantages. Apply to: 1) the various types of retaining walls north of the vertical and horizontal drainage; 2) highway, railway embankment, shoulders, soft ground drainage; 3) tunnel, underpass drainage; 4) gray-power dam and water conservancy dam drainage ; 5) highway median strip drainage and the protection of vegetation; 6) outdoor sports venues drainage; 7) lateral horizontal drilling empty drainage; to 8 drainage slope) easy Slump; 9) roof garden and flower bed drainage; 10) hillside Water conservation; 11) for planting underground drainage; 12) low-lying drainage and saline transformation of the system. Drainage mechanism of soft water pipe is coated on the non-woven fabric on top of the spring wire and corrosion-resistant, high-strength synthetic filament the seepage composite layer filtering role, chippings, clay, fine sand, particulate organic substance such as the resistance in the drain outside Engineering harmful permeated water in under pressure, the by permeation composite layer into the seepage conduit, and then by the catheter to drain away, to achieve infiltration, drainage function, to achieve the purpose of the clean water emissions. Tend to be excluded in civil engineering, water conservancy project construction, seepage and groundwater of the soil, rock groups such as the project itself. The presence of water, civil engineering, water conservancy project construction will produce many adverse effects as well as various forms of harm and destruction. The same time, water is an important factor to affect the stability of civil engineering, water conservancy project construction, the presence of water causes the soil softening, increasing soil weight, reduce internal friction and cohesion of soil. In addition, water pooled and impact, would cause soil erosion, dams and protection Dipo facilities construction, new materials have the double effect of filtration and drainage needs to be applied to reduce the adverse impact of the water for a variety of construction projects. The product connection: connection principle of construction in order to facilitate the reliable 50mm permeable tube tunnel ring to length production the vertical 100mm permeable tube length 6-30m through connection with ancillary tees, you can easily connect. Lined with steel wire: high-strength spring hard wire, phosphate antirust treatment, the outer coating PVC (resistance heating Law). Filter layer: non-woven filtering layer. Of permeable and coating materials: the use of high-strength nylon yarn, the warp and weft use a special fiber. Then the material: special strength PVC adhesive.
