Expansive soil cutting retaining wall
The invention belongs to the technical field of slope support engineering, and particularly relates to an expansive soil cutting retaining wall. The expansive soil cutting retaining wall comprises a side ditch and a retaining wall body, wherein the foundation burial depth of the retaining wall body is not less than 1.5m, and is not less than 0.3m lower than the bottom surface of a side ditch masonry; the side ditch and the retaining wall body are constructed synchronously; a mortar rubble platform is used for sealing the space between the side ditch and the retaining wall body; the bottom of the mortar rubble platform is backfilled and sealed by using mortar rubbles; the wall back of the retaining wall body is continuously provided with a permeable woven bag sand gravel inverted filter andis paved with a composite drainage network; a water-resisting layer is arranged in a range of 0.3m below a drainage hole at the bottommost of the wall back; and concrete with the same mark number asthe retaining wall body is adopted for sealing. The expansive soil cutting retaining wall has good stability, the deformation of the wall surface can be reduced, and the occurrence of landslide is reduced.
本发明属于边坡支护工程技术领域，具体涉及膨胀土路堑挡土墙；包括侧沟和挡土墙本体，挡土墙本体基础埋深不宜小于1.5m，且低于侧沟砌体底面不小于0.3m，侧沟和挡土墙本体应同步施工，侧沟和挡土墙本体之间使用浆砌片石平台封闭，浆砌片石平台底部使用浆砌片石回填封闭，挡土墙本体墙背连续设置有透水编织袋装砂砾石反滤层并铺设有复合排水网，墙背最底排泄水孔以下0.3m范围内设隔水层，采用与挡土墙本体同标号砼封闭；本发明具有较好的稳定性，能够减小墙面变形，并且减少滑坡的发生。
