Rapid construction method for stripping excavation of foundation pit on subway tunnel
The invention provides a rapid construction method for strip-drawing excavation of a foundation pit on a subway tunnel. The rapid construction method is used for solving the technical problems that during strip-drawing excavation of the foundation pit, the excavation width is generally conservative, the project input cost is high, the construction period is long, and the foundation pit cannot be rapidly excavated in a strip-drawing mode. According to the method, the automatic monitoring network and the model grid are adopted as the basis, subway tunnel deformation monitoring data are combined, the stripping width is increased after specialist argumentation, normal operation of an existing subway is effectively guaranteed, the construction period is shortened, considerable economic benefits are achieved, and the method is worthy of popularization and application. Conservative construction and restriction on the construction period due to the fact that construction is carried out simply according to the designed stripping width during stripping excavation of the foundation pit are avoided.
本发明提出了一种用于地铁隧道上基坑抽条开挖的快速施工方法，用以解决基坑抽条开挖时开挖宽度一般比较保守、工程投入成本高、工期较长，基坑无法快速化抽条开挖的技术问题。本发明通过采用自动化监测网与模型网格为基础，结合地铁隧道变形监测数据，经专家论证后增加了抽条宽度，有效保障了既有地铁的正常运营，缩短了施工周期，具有可观的经济效益，避免出现基坑抽条开挖时单纯按照设计给出的抽条宽度进行施工，导致施工相对保守，制约施工工期。
