Construction method of diaphragm wall joint water stop
The invention discloses an underground diaphragm wall joint water stop construction method which comprises the following steps: S1, excavating a first-stage groove section by using a grooving machine, protecting a wall by using slurry during grooving, and cleaning hard objects which do not fall off by using a wall brushing device after the first-stage groove section is completed; s2, a first reinforcement cage is manufactured, I-shaped steel is welded to the first reinforcement cage, and the first reinforcement cage is placed in the first-stage groove section; s3, a second-stage groove section is excavated through the trenching machine, slurry is adopted for protecting the wall during trenching, and after the second-stage groove section is completed, a wall brushing device is used for cleaning hard objects which do not fall off; s4, a second reinforcement cage is manufactured, the second reinforcement cage is placed in the second-stage groove section, then a grouting pipe is arranged at the inner corner, facing one side of the second reinforcement cage, of the I-shaped steel in the adjacent groove section, and grouting treatment is conducted on the second-stage groove section; s5, after all the groove sections are machined, a high-pressure jet grouting pile is installed on the outer side between every two adjacent groove sections so that water can be stopped between every two adjacent groove sections; according to the technical scheme, the water stopping effect at the joint of the underground diaphragm wall is improved.
本发明公开一种地连墙接头止水的施工方法，包括步骤S1、利用成槽机开挖一期槽段，成槽时采用泥浆护壁，一期槽段完成后用刷壁器清理未脱落的硬物；S2、制作第一钢筋笼，并在第一钢筋笼上焊接工字钢，将第一钢筋笼放入一期槽段中；S3、利用成槽机开挖二期槽段，成槽时采用泥浆护壁，二期槽段完成后用刷壁器清理未脱落的硬物；S4、制作第二钢筋笼，将第二钢筋笼放入二期槽段中，然后在相邻的槽段中的工字钢朝向第二钢筋笼一侧的内角处设置注浆管，对二期槽段进行注浆处理；S5、当所有槽段加工完成后，在相邻的两个槽段之间的外侧安装高压旋喷桩，以使相邻的两个槽段之间止水；本发明技术方案提高了地连墙接缝处的止水效果。
