        soft permeable pipe is a kind of filter down through the (row) of new pipe water action, because of its unique design principle of products and excellent properties of the constituent materials, it ranks, seepage effect, the use of "capillary" phenomenon and the "siphon" principle, set the water absorption, permeability to make smooth reading, drainage, meet with pressure resistance and permeability and filtration effect of engineering design requirements.
    mainly applies to: 1) all kinds of retaining wall on the north side of the vertical and horizontal drainage; 2) highway, railway subgrade, shoulder, drainage of soft soil foundation; 3) drainage tunnel, underground drainage; 4) electric ash dam and water conservancy dam highway; 5) the central isolation belt drainage and protection of vegetation 6) outdoor sports venues; drainage; 7) horizontal drilling drainage; 8) to landslide drainage slope; 9) Roof garden and flower bed drainage; 10) slope land and water conservation; 11) underground drainage site preparation works; 12) the low-lying saline alkali land drainage and modification system.
