Rapid repairing structure for shallow landslide of above-second-level soil slope and construction method thereof
The invention discloses a rapid repairing structure for a shallow landslide of an above-second-level soil slope and a construction method thereof. According to the repairing structure, a step is excavated on a landslide part of a landslide body, multiple layers of backfill bagged soil are constructed on the step in a filling manner, and geogrids are laid at the bottom of each layer of backfill bagged soil; reserved parts of the geogrids are reversely wrapped along the backfill bagged soil on the upper portions of the geogrids and tensioned to the required tensile strength, the geogrids are fixed to the top face of the backfill bagged soil through U-shaped nails to form reverse wrapping, and the reverse wrapping geogrids and the geogrids adjacent to the upper layer are fixedly connected through U-shaped nails and are both fixed to the top face of the corresponding backfill bagged soil; and a plurality of steel bars are implanted into the bottom of a reinforced body formed by combining the backfill bagged soil and the geogrids. The repairing structure plays a supporting role, meanwhile, energy dissipation is achieved on expansion deformation generated by soil in the slope through self deformation, the repairing effect is good, construction is easy and convenient, the technical requirements for personnel are low, the construction period is short, the number of machines is small, risks are low, cost is low, and environment friendliness is achieved.
本发明公开了一种二级以上土质边坡浅层滑坡快速修复结构及其施工方法，修复结构为：滑坡体的滑塌部开挖有台阶，台阶上填筑有多层回填袋装土，每层回填袋装土的底部均铺设有土工格栅，土工格栅的预留部沿土工格栅上部的回填袋装土反包并张拉至所需抗拉强度，通过U型钉将土工格栅固定于回填袋装土的顶面，形成反包，反包的土工格栅与邻近上层的土工格栅通过U型钉固定连接且均固定于对应的回填袋装土顶面，回填袋装土与土工格栅组合的加筋体底部植入多个钢筋。本发明修复结构起支护作用的同时通过自身变形对坡内的土质产生的膨胀变形实现消能，修复效果好，施工简便，人员技术要求低，工期短，机械少，风险低，成本低，绿色环保。
