PURPOSE: A polyethylene honeycomb drain system in a rear part of a retaining wall around an apartment house complex under earth work is provided to prevent collapse under a landslide by draining rainwater and water efficiently and quickly and restricting the polyethylene honeycomb structure from being clogged. CONSTITUTION: A polyethylene honeycomb drain system(900) is composed of a retaining wall(100) having a lower drain hole, a lower gutter(200) contacted to a lower rear part of the retaining wall, a waterproof mat(300) contacted to the rear part of the retaining wall to prevent moisture from being infiltrated into the concrete retaining wall, a honeycomb drain member(400) contacted to the waterproof mat to obtain a drain space, a cleaning tube(500) penetrating a center of the honeycomb drain member, and a wood fiber formed of a grille net in a rear part of the honeycomb drain member to restrict earth and sand outflow. An end of a drain passage(160) is placed in a drain connecting pipe(230). |
