Concrete retaining wall revetment is an important revetment way, and seepage drainage structure is an important part of concrete retaining wall revetment. The seepage pipe of the general concrete retaining wall revetment is directly perpendicular to the bank slope every several tens of meters, to drain away soil permeable water, prevent soil permeable water from accumulating, and reduce the pressure of concrete retaining wall revetment structure.
