Soft Permeable Pipe - Good Filtration and Drainage Property
Soft permeable pipe is a new type of pipe that has anti water filtering function. It is supported by the anti rust spring coil, and form into high compressive soft structure, non woven fabric as lining filtering. This is in order to make mud sand impurities can not enter the pipe, so as to achieve the function of net water seepage. The outer coating layer is formed around the polypropylene fiber has excellent water absorption, can quickly collect excess water in the soil. And rubber reinforced wall coating layer and the spring steel tube body become organic integration has a good full range of water permeability function, osmotic water enters into the tube smoothly. But the sand mud impurities are blocked outside the tube, so as to achieve the purpose of water permeability, filtration and drainage.
SPP-1: Soft permeable pipe.
SPP-2: The inner of soft permeable pipe is anti rust spring coil.
Design principle and advantages of soft permeable pipe
Soft permeable pipe overcomes many shortcomings which the other drainage pipes have. Because of its unique product design principle and constituent materials with excellent performance, its drainage and water seepage effect are strong. Use of "capillary" phenomenon and "siphon" principle, set water absorption, permeable and drainage as a whole. With engineering design requirements of pressure resistance, water permeability and anti filtration. It will not because of the geological and geographical temperature changes that occur fracture, and can achieve the effect of discharge clean water. In addition, it will not cause the secondary pollution to the environment, belongs to a new type of environmental protection product. Its construction is simple, no joints, no special requirements on the geology and topography, any places where need subsurface drainage can be used.
