Retaining wall drainage system and construction method thereof
The invention provides a retaining wall drainage system and a construction method thereof.The system comprises a drainage channel in a retaining wall body, the drainage channel penetrates through the front portion of a retaining wall, is arranged in front-wall backfill concrete and is connected with a water inlet of a front-wall drainage ditch, and a concrete water-resisting layer is arranged at the position, at an inlet of the drainage channel, of the rear portion of the retaining wall; longitudinal water grooves are formed in the concrete water-resisting layer and connected with a drainage channel through transition water grooves, water-permeable non-fine concrete plates are arranged in three directions of backfill soil behind the wall, and concrete sealing layers are arranged at the tops of the water-permeable non-fine concrete plates on the two sides of the backfill soil. By arranging the longitudinal water tank behind the wall, accumulated water behind the wall is effectively collected, and the discharging and isolating functions are achieved; the drainage channel and the transition water tank are arranged, so that the drainage channel is smooth, and the drainage effect behind the wall is greatly improved; the water flow surface of the drainage channel in front of the wall is lower than the top of the backfill concrete in front of the wall and the top of the ditch, thereby preventing slurry from polluting the wall surface.
本发明提供一种挡墙排水系统及其施工方法，系统包括挡墙墙身内的排水通道，排水通道穿过挡墙墙前，设置于墙前回填混凝土内，并与墙前排水沟的入水口相连，挡墙墙后在排水通道入口处设有混凝土隔水层，在混凝土隔水层内设有纵向水槽，纵向水槽通过过渡水槽与排水通道相连，在墙后回填土三个方向均设置透水无砂混凝土板，回填土两侧的透水无砂混凝土板顶部设有混凝土封闭层。通过设置墙后纵向水槽，有效汇集墙后积水，实现排送及隔离功能；设置的排水通道及过渡水槽，顺畅了排水通道，大幅提高了墙后排水效果；墙前排水通道流水面低于墙前回填混凝土顶部及水沟顶部，防止出现泥浆污染墙面的现象。
