Construction improvement method for anti-sloughing grooving of water-rich soft geology
The invention discloses a water-rich soft geology anti-collapse grooving construction improvement method, and relates to the technical field of foundation pit engineering construction.The method comprises the following steps that S1, the hydrogeology and the engineering geology of an interval are determined; s2, selecting a representative geological condition section as a test pile section; s3, field leveling is conducted after pile testing; s4, pile position arrangement is carried out after site preparation; s5, carrying out model selection on grooving equipment; s6, conducting structural arrangement of the guide wall; s7, slurry is prepared; s8, slurry grouting is carried out; and S9, carrying out quality detection. According to the method, the three-shaft stirring piles are used for reinforcing the guide wall and the underground diaphragm wall, the foundation bearing capacity of a foundation pit is improved, meanwhile, due to the fact that mud contains cement, the performance of the mud is greatly improved, and therefore the technical problem that in the water-rich soft geology, hole collapse is likely to happen to grooving of the underground diaphragm wall is effectively solved; the construction quality and efficiency of the underground diaphragm wall are improved, and the construction cost is saved.
本发明公开了一种富水松软地质防塌成槽的施工改进方法，涉及基坑工程施工技术领域，包括以下步骤：S1、明确区间的水文地质和工程地质；S2、选择具有代表性的地质条件段作为试桩段；S3、试桩后进行场地整平；S4、场地整后进行桩位布置；S5、进行成槽设备的选型；S6、进行导墙的结构布置；S7、进行泥浆的制备；S8、进行泥浆的灌浆；S9、进行质量检测。该方法通过使用三轴搅拌桩对导墙和地下连续墙进行加固，提高了基坑的地基承载力，同时由于泥浆中含有水泥成分，大大改良了泥浆性能，从而有效地解决了富水松软地质中地下连续墙成槽容易“塌孔”的技术难题，提高了地下连续墙的施工质量和效率，节约了施工成本。
