The drainage mechanism of the water pipe is through the filtration function of the water seepage composite layer which is composed of the non-woven fabric coated on the spring steel wire and the corrosion-resistant and high-strength synthetic fiber filament, so that various fine gravel, clay, fine sand, Organic matter and the like are blocked outside the drainage pipe, and permeable water harmful to the project enters the seepage water guiding pipe through the infiltrating composite layer under the pressure, and then is drained away by the pipe to realize the function of seepage and drainage to reach the discharge of clean water purpose. In civil engineering and water conservancy projects, seepage and groundwater of soils, rock-based projects and so on are often excluded. The existence of water can have many adverse effects on civil engineering, water conservancy and other construction projects as well as various forms of harm and destruction.
