The base plate made of HIPS, HDPE or PVC is punched into a conical boss or a convex point with stiffening ribs (or a hollow cylindrical porous plate), with a width of 1 - 3 meters and a length of 4 - 10 meters or more. A layer of filtering geotextile is glued to the top surface of the conical boss to prevent soil particles from passing through, thereby avoiding blockage of the drainage channel and making the drainage channel drain smoothly.
