Underground structure internal pile-replacing-column construction method
The invention provides an underground structure internal pile-replacing-column construction method, and relates to the technical field of underground structure construction. Comprising the steps of field leveling and measurement positioning; piling operation is carried out according to the construction sequence of first outer piles and then prefabricating high-strength concrete pipe piles; the prefabricated high-strength concrete pipe piles entering the field are planted according to sections, and all the sections of the prefabricated high-strength concrete pipe piles are connected through spherical flange hoops; earth is excavated to the negative first layer through a reverse construction method, an assembly type outer wall is installed to serve as an outer wall support, a waterproof part is arranged outside, joint concrete is poured, and pile head steel bars, column-plate connecting steel bars and plate haunching steel bars are connected to connecting joints of columns and plates to form plate-column combined joints; the step 3 is repeated, earth is excavated to the negative second layer, the step 4 is repeated, and downward excavation is completed in sequence; cleaning and polishing the surface of the outer pile to meet use conditions; the underground structure is formed after the pile replaces the column. According to the construction method for replacing the column with the pile in the underground structure, the overall stability of the component can be effectively improved, the construction procedure is simplified, and the construction efficiency is improved.
本发明提供一种地下结构内部桩代柱施工方法，涉及地下结构施工技术领域。包括场地整平，测量定位；按照先外桩，后预制高强混凝土管桩的施工顺序进行打桩作业；进场的预制高强混凝土管桩按节植桩，每段预制高强混凝土管桩之间通过球体型法兰套箍相连；利用逆作法挖土至负一层，安装装配式外墙做外墙支护，外设防水，浇筑节点砼，在柱与板的连接节点上连接桩头钢筋、柱板连接钢筋、板加腋钢筋形成板柱结合节点；重复步骤3，挖土至负二层，重复步骤4，依次下挖完成；清理打磨外桩表面，达到使用条件；自此桩代柱完成，地下结构形成。本发明使用的本地下结构内部桩代柱施工方法，可有效提高构件整体稳定性，减化施工工序，提升施工效率。
