Subway station construction method, foundation pit excavation method and foundation pit
The invention relates to a subway station construction method, a foundation pit excavation method and a foundation pit. The subway station construction method comprises the following steps that (1), a subway station is divided into a plurality of rectangular subunits in the length direction of the subway station; (2), tunneling construction is carried out on each subunit by adopting a vertical shaft tunneling machine, concrete side walls and temporary side walls are constructed in the tunneling process, and an inner support is constructed between the two concrete side walls and/or an inner support is constructed between the concrete side walls and the temporary side walls; (3), when the concrete side wall is constructed to a set height, a temporary retaining wall is constructed at the top of the concrete side walls; (4), tunneling is continuously carried out to the set depth of the foundation pit, tunneling is stopped, and the vertical shaft tunneling machine is withdrew from the foundation pit; (5), a concrete bottom plate, a concrete middle plate and a concrete top plate are sequentially constructed from bottom to top, and the inner supports are sequentially dismantled from bottom to top; and (6), the temporary retaining wall, the temporary side wall and the remaining inner support are dismantled, and the ground is restored.
本发明涉及一种地铁车站施工方法、基坑开挖方法及基坑。地铁车站施工方法，包括以下步骤：（1）将地铁车站沿其长度方向分割成若干个呈矩形的子单元；（2）采用竖井掘进机对各个子单元掘进施工，在掘进过程中施工混凝土侧墙和临时侧壁，同时在两个混凝土侧墙之间施工内支撑，和/或混凝土侧墙与临时侧壁之间施工内支撑；（3）在混凝土侧墙施工至设定高度时，在混凝土侧墙的顶部施工临时挡墙；（4）继续掘进至基坑的设定深度，停止掘进，将竖井掘进机从基坑内退出；（5）由下向上依次施工混凝土底板、混凝土中板以及混凝土顶板，并由下向上依次拆除内支撑；（6）拆除临时挡墙、临时侧壁以及剩余内支撑，恢复地面。
