Waterproof method for joint of TRD and drilling secant pile
The invention relates to the technical field of foundation pit support, and discloses a waterproof method for the joint of TRD and a drilling secant pile, which comprises the following steps of: S1, leveling a site, and measuring and setting out; s2, a high-pressure jet grouting drilling machine is in place, a drill bit is aligned with the center of the pile position, and drilling is conducted; s3, a sleeve is inserted into the hole, and a grouting pipe with a nozzle is inserted into the sleeve; s4, a high-pressure grouting machine is started, cement paste is injected, and the grouting pipe is lifted while the cement paste is injected; s5, after high-pressure grouting is completed, static pressure grout supplementing is conducted; and S6, after the high-pressure jet grouting pile is completed, the high-pressure jet grouting drilling machine, the high-pressure grouting machine and the grouting pipe are moved, and construction of the next pile position is conducted. The construction progress is accelerated, the construction safety performance is improved, and the construction cost is reduced.
本发明涉及基坑围护技术领域，且公开了TRD与钻孔咬合桩衔接处防水方法，包括：步骤S1，场地平整，测量放样；步骤S2，高压旋喷钻机就位，使钻头对准桩位中心，进行钻孔；步骤S3，在孔内插入套管，套管内插入带有喷嘴的注浆管；步骤S4，打开高压注浆机，注入水泥浆，边注水泥浆边提升注浆管；步骤S5，高压注浆完成后进行静压补浆；步骤S6，高压旋喷桩完成后，对高压旋喷钻机、高压注浆机和注浆管移位，进行下一根桩位施工。本发明不仅加快了施工进度，提高了施工安全性能，还降低了施工成本。
