Fabricated multifunctional retaining wall structure and construction method thereof
The invention discloses a fabricated multifunctional retaining wall structure and a construction method thereof and belongs to the technical field of retaining walls. The PC piles are sequentially connected, and the adjacent PC piles form a containing space with the reinforcing piles. The construction method comprises the following steps that the PC piles are sequentially connected and then placed into a construction groove, and water stop strips are arranged at the joints; and after reinforcing piles are placed in the placing spaces, curing materials are injected. The construction method of the side wall of the underground structure comprises the following steps: constructing retaining walls on two sides of the channel; a first transverse support is arranged at the upper end of the retaining wall when excavation is conducted by 2 m; when 2/3 of excavation is conducted, a second transverse support is arranged at the 1/2 depth position; when a specified depth is excavated, the bottom plate is constructed and connected with the PC pile into a whole; removing the first transverse support after the bottom plate is formed; a top plate is constructed after displacement deformation of the PC pile is completed; and after the top plate is completed, the second transverse support is detached. The side wall can be used as a side wall of an underground structure for a long time under the working conditions that the population density is large and the surrounding construction environment needs to be strictly controlled, the construction period is shortened, and the construction cost is reduced.
一种装配式多功能挡土墙结构及其施工方法，属于挡土墙技术领域。PC桩依次连接，相邻PC桩构成有加强桩的容置空间。施工方法如下：PC桩依次连接后放入施工槽并在连接处作止水条带；放置空间内置入加强桩后注入固化材料。作为地下结构侧壁的施工方法如下：通道两侧构筑挡土墙；开挖2m时在挡土墙上端设第一道横向支撑；开挖2/3时，在1/2深度处设第二道横向支撑；开挖规定深度时，施工底板并与PC桩连成整体；底板成型后拆除第一道横向支撑；PC桩位移变形完成后施工顶板；顶板完成后，拆除第二道横向支撑。本发明适应人口密度大、周边施工环境须严格控制的工况可作为地下结构的侧壁长期使用，不仅缩短工期，而且降低了建造成本。
