Soft water pipe is a rust-proof coil support tube to form a high compressive strength of soft-type structure, non-woven filter liner, so that sediment contamination can not enter the tube, so as to achieve a net effect of water seepage. Polypropylene fiber outer coating layer has excellent water absorption burning, can rapidly collect excess moisture in the soil. Rubber reinforced embassy wall coating layer and the spring steel ring tube into an organic whole, has a good all-round permeable features a smooth penetration of water infiltration tube, while the sediment impurities are blocked at the controls, so as to achieve permeability, filtration, drainage at one go purposes. Is widely used in a variety of civil engineering, in reducing the water table, soft soil, rock and soil to prevent collapse, to improve soil quality and other aspects, tangible results, the design, construction unit the ideal set of drainage reinforcement equipment.
