Foundation pit excavation supporting method based on excavation compensation method and complete equipment thereof
The invention relates to the technical field of foundation pit construction, in particular to a foundation pit excavation supporting method based on an excavation compensation method and complete equipment thereof.The foundation pit excavation supporting method comprises the following steps that a foundation pit is longitudinally segmented and vertically arranged in a layered mode, and fender post construction is conducted; a lining component is placed along the excavation inner contour of the foundation; excavation supporting equipment is fixedly installed in the first layer, and when the first layer is excavated, excavation compensation agents are injected along with excavation; after the excavation operation of the first layer is finished, slurry in the foundation pit is pumped away through the foundation pit excavation supporting equipment, and the deslagging work of the first layer is completed; a lining piece is additionally arranged on the lining piece, and supporting of a second layer is completed; and the next step is circulated for second-layer excavation. Non-blasting low-disturbance excavation of the foundation pit is achieved on the basis of excavation supporting equipment, meanwhile, water and soil loss in the excavation process is reduced to the maximum extent on the basis of an excavation compensation agent, and effective supporting of the foundation pit is achieved through auxiliary prefabricated pipe pieces and wall thickness filling grouting.
本申请涉及基坑施工技术领域，具体而言，涉及一种基于开挖补偿法的基坑开挖支护方法及其成套装备，包括如下步骤：将基坑纵向分段、竖向分层设置并进行围护桩施工；将衬砌构件沿所述基础的开挖内轮廓放置；并在其内部固定安装开挖支护设备，在进行第一层开挖时，随挖随注入开挖补偿剂；当第一层的开挖作业结束后，通过所述基坑开挖支护的设备抽去所述基坑内的泥浆，完成第一层除渣工作；在所述衬砌件上加装衬砌件，完成第二层的支护；循环下一步骤进行第二层开挖。本发明基于开挖支护装备实现基坑的非爆破低扰动开挖，同时基于开挖补偿剂最大限度的减少了开挖过程中的水土流失，辅助预制管片和壁厚充填注浆实现了基坑的有效支护。
