Row pile and concrete wall combined support and construction method thereof
The invention discloses a row pile and concrete wall combined support and a construction method thereof, a row pile structure, a pre-stressed anchor rod structure and a cast-in-place concrete wall structure are combined to form a combined support body, after construction of the row pile structure is completed, the cast-in-place concrete wall structure is poured on the side, close to a foundation pit, of a row pile, and the cast-in-place concrete wall structure and the row pile structure are connected through embedded steel bars; pre-stressed anchor rod through-wall steel sleeves are pre-buried in a cast-in-place concrete wall structure, after earth is excavated to the elevation of the pre-stressed anchor rods, the pre-stressed anchor rods are constructed through the steel sleeves, and after the strength of anchor rod grouting bodies meets the requirement, bearing plates are installed at orifices for direct tensioning. According to the method, traditional inter-pile sprayed concrete simple retaining walls are replaced, a steel waist beam is omitted, inter-pile soil is supported through the reinforced concrete wall, the bearing plate is directly pressed on the concrete wall, the double requirements of inter-pile supporting in row and underground water interception are met, foundation pit dewatering or a waterproof curtain does not need to be adopted, the construction efficiency is high, pollution to the surrounding environment is small, and the construction cost is low. Meanwhile, construction period is saved and cost is reduced.
本发明公开了一种排桩和混凝土墙联合支护及其施工方法，排桩结构、预应力锚杆结构与现浇混凝土墙结构组合联合支护体，排桩结构施工完成后，在排桩靠基坑侧浇筑现浇混凝土墙结构，现浇混凝土墙结构与排桩结构间采取植筋连接，现浇混凝土墙结构内预埋预应力锚杆穿墙钢套筒，土方开挖至预应力锚杆标高后，通过钢套筒施工预应力锚杆，锚杆注浆体强度满足要求后在孔口安装承压板直接进行张拉。本发明代替传统桩间喷射混凝土简易护壁，取消钢腰梁，利用钢筋混凝土墙支护桩间土，通过承压板直接压在混凝土墙上，实现排桩桩间支护和地下水截水的双重要求，无需采取基坑降水或止水帷幕，施工效率高，对周边环境的污染小，同时节约工期、降低造价。
