Moreover, a large number of materials and processes are required, a large amount of labor is needed, the construction period is long, and the cost is high. The inner side layer of the groove is generally made of plain concrete, the surface friction is large, dirt is easily accumulated in the ditch, the normal drainage is affected, and the workload of the later maintenance and cleaning is large. For the ordinary brick-laid foundation concrete drainage ditch, only the concrete surface layer is used for anti-seepage, and it is difficult to guarantee the anti-seepage capacity.
