Pile steel support construction method
The invention discloses a construction method for a pile steel support. The construction method comprises the following steps that firstly, fender posts are formed; step 2, pile steel support; thirdly, the bottom of the foundation pit is excavated; step 4, constructing a lower half main body; 5, constructing an upper half main body; and sixthly, pile steel replacement supports are dismantled. And in the fourth step, the lower half main body is constructed, specifically, the lower half main body is constructed above the soil body between the two fender posts, and a pile steel replacement support is constructed on the inner face side of the lower half main body. In the fifth step, the construction of the upper half main body is that after the lower half main body and the pile steel support are replaced to reach the strength, the pile steel support is dismantled; and constructing an upper half main body on the lower half main body. Due to the fact that after the lower half body is constructed, the upper half body is constructed on the basis that the lower half body is constructed, rapid forming of the track space is achieved, construction efficiency is improved, and the problem that at present, station side walls and bottom plates are poured separately, and then vaults are poured at the upper ends of the station side walls to form the station space, and construction efficiency is low is solved.
本发明公开了一种桩钢支撑施工方法，包括如下步骤：步骤一、围护桩成型；步骤二、桩钢支撑；步骤三、开挖基坑底；步骤四、下半主体的构建；步骤五、上半主体的构建；步骤六、拆除桩钢换撑。所述步骤四、下半主体的构建为：在两个围护桩之间的土体上方构建下半主体，并在下半主体内面侧构建桩钢换撑。所述步骤五、上半主体的构建为：待下半主体和桩钢换撑达到强度后拆除桩钢支撑；在下半主体上施工作业构建上半主体。由于在下半主体构建后，上半主体在下半主体构建完成的基础上构建，实现了轨道空间的快速成型，提高了施工效率，解决了目前车站边墙和底板分开浇筑，再在车站边墙的上端浇筑拱顶构成车站空间施工效率低的问题。
