Pipeline protection structure and foundation pit construction method
The invention belongs to the technical field of foundation pit construction, and provides a pipeline protection structure and a foundation pit construction method.The pipeline protection structure comprises a plurality of MJS reinforcing bodies and two soil retaining reinforcing modules; the multiple MJS reinforcing bodies are evenly arranged, meshed with one another and located at the positions, corresponding to pipelines, of a foundation pit. The MJS reinforcing body corresponding to the waterproof curtain of the foundation pit is engaged with the waterproof curtain to form a closed waterproof curtain; the two soil retaining reinforcing modules are arranged at the two ends of the pipeline in the length direction correspondingly. Each soil retaining reinforcing module comprises two sets of reinforcing fender posts and a baffle, the two sets of reinforcing fender posts are arranged on the two sides of the end of the pipeline correspondingly, and the baffle is connected between the two sets of reinforcing fender posts. The vertical upper end of the baffle is connected with a top beam on the foundation pit, and the vertical lower end of the baffle extends to the bottom of the foundation pit so as to achieve the soil retaining effect when the foundation pit is excavated. The method is safe and reliable, and pipeline deformation can be effectively controlled.
本发明属于基坑施工技术领域，提供一种管线保护结构及基坑施工方法，其中的管线保护结构包括多条MJS加固体以及两个挡土加强模组；多条所述MJS加固体匀布置且相互咬合，位于基坑位置的管线对应处；与基坑止水帷幕对应的所述MJS加固体与所述止水帷幕相互咬合，以形成封闭式止水帷幕；两个所述挡土加强模组分别设置在管线长度方向的两端；每个所述挡土加强模组均包括两组加强围护桩以及挡板，两组所述加强围护桩分别设置在管线端部的两侧，所述挡板连接在两组加强围护桩之间；所述挡板的竖向上端与基坑上的冠梁连接，所述挡板的竖向下端延伸至基坑底部，以形成基坑开挖时的挡土作用。本发明安全可靠，可有效控制管线变形。
