Secant pile water seepage treatment method
The invention provides a secant pile water seepage treatment method, and relates to the technical field of underground construction engineering. The secant pile water seepage treatment method includesthe steps that S1, a plurality of grouting holes are formed in secant pile plain piles on the outer side of the wall of a vertical shaft, and the grouting holes penetrate through the secant pile plain piles to be communicated with a foundation at the outer end; S2, grouting pipes inserted into the inner ends of the formed grouting holes; S3, grouting is conducted on the outer side of the verticalshaft through the grouting pipes by using a grouting machine; and S4, decompressing and dewatering wells are dug on a foundation on the outer side of a vertical shaft awning, and the number of the dug decompressing and dewatering wells in each direction is determined according to the water gushing degree in the wells and site construction conditions. When the secant pile water seepage treatment method is used for construction, and special equipment is not needed, the construction method is simple, so that the water seepage problem of vertical shaft secant piles can be effectively solved, waterless operation of the vertical shaft is guaranteed, and meanwhile the reinforcing effect on an enclosure structure is achieved.
本发明提供一种咬合桩渗水的处理方法，涉及地下建筑工程技术领域。该咬合桩渗水的处理方法，包括以下步骤：S1.在竖井井壁外侧的咬合桩素桩上开设多个注浆孔，注浆孔穿过咬合桩素桩通至外端的地基；S2.在开设好的注浆孔内端插入注浆管；S3.使用注浆机通过注浆管在竖井外侧进行注浆；S4.在竖井罩棚外侧的地基上打设减压降水井，各方位减压降水井的打设数量根据井内涌水程度以及现场施工条件而定。通过该方法施工时，无需特殊设备，工法简单，可有效解决竖井咬合桩渗水问题，保证竖井的无水作业，同时具有对围护结构的补强作用。
