Although the problems of the traditional hard drainage system can be solved, the root of the plant continuously erodes the geotechnical bag in the growth process of the plant, so that the geotechnical bag is easy to collapse along with the growth of the plant, and the drainage ditch is filled or even cannot be used.
On the other hand, in the construction process of the side slope, particularly under the working condition that the surface runoff is large and the water source is higher, the surface drainage function of the side slope must be considered in the construction process, and conventionally, drainage is extracted from a high place to a low place through a water pump and a drainage pipe, but one of the methods is that the electric power dependence is large, the drainage efficiency is not as high as that of a drainage ditch, and personnel are required to nurse.
