Construction method of deep foundation pit adjacent to subway
The invention discloses a construction method of a deep foundation pit adjacent to a subway, and relates to the technical field of foundation pit construction, and the construction method comprises the following steps: surveying surrounding environment conditions, engineering geological conditions and hydrogeological conditions of a to-be-excavated area, and obtaining comprehensive construction conditions of the to-be-excavated area; surveying and setting out, and after a foundation pit excavation sideline is drawn, carrying out excavation; after excavation is completed, the side wall of the foundation pit is supported through a supporting device; the two sets of supporting devices are symmetrically arranged in the foundation pit body and used for supporting the two side walls of the foundation pit body correspondingly, and each set of supporting device comprises a supporting plate used for supporting the side walls of the foundation pit. The supporting device further comprises a positioning plate used for abutting against the bottom of the foundation pit. When the foundation pit body is supported, firstly, the supporting plate is installed to abut against the side wall of the foundation pit so as to support and reinforce the side wall, and then the positioning plate is installed to abut against the corresponding bottom of the side wall so as to position and fix the supporting plate, so that the stability of the supporting plate is higher.
本发明公开了一种邻近地铁深基坑的施工方法，涉及基坑施工技术领域，包括如下步骤：勘察待开挖地区的周边环境条件、工程地质条件以及水文地质条件，获得待开挖地区的综合施工条件；测量放线，画出基坑开挖边线后实施开挖；开挖完成后通过支护装置对基坑侧壁进行支护；所述支护装置于基坑主体中呈对称布设有两组，分别用于对基坑主体两侧壁进行支撑，各组支护装置均包括用于支撑基坑侧壁的支撑板；所述支护装置还包括用于与基坑底部抵接的定位板；在对基坑主体进行支撑时，首先安装支撑板与基坑侧壁抵接，以实现对侧壁的支撑加固，而后安装定位板与侧壁相应的底部抵接，实现对支撑板的定位固定，以使支撑板稳定性更高。
