Construction device and method for anti-seepage of continuous wall

Abstract

The invention discloses an anti-seepage construction device and method for a continuous wall. The anti-seepage construction method comprises the following steps that (A) the size of a prefabricated connector pipe is selected according to the thickness of the continuous wall, and a waterproof groove is fixedly formed in the outer side wall of the prefabricated connector pipe; (B) after steel bars are installed on the construction section of the continuous wall, concrete is poured; (C) after the concrete is solidified, a grouting pipe is inserted into the waterproof groove, grouting holes are evenly formed in the pipe wall of the grouting pipe, a grouting machine is connected with the grouting pipe, and anti-seepage grout is injected into the waterproof groove; and (D) after the anti-seepage grout is solidified, construction of the next continuous wall is started. The anti-seepage construction device and method for the continuous wall have the advantages that concrete pouring is convenient, the construction efficiency is improved, and the interlocking force of the continuous walls on the two sides is improved through the waterproof groove; and by changing the seam structure of traditional continuous walls and injecting the anti-seepage grout into the waterproof groove, the waterstop effect is achieved, and the anti-seepage performance is improved.

Description

technical field [0001] The invention relates to a leak-proof construction device and method of a continuous wall. Background technique [0002] The construction of the connecting wall is generally made of self-sealing concrete with high water resistance. The continuous wall itself generally has little leakage, and the leakage generally comes from the joint joint. Since the diaphragm wall is constructed in sections, when each section of concrete is poured, a joint pipe with a diameter that basically matches the thickness of the diaphragm wall is inserted vertically at the section of the diaphragm wall as a connection joint with the construction of the next section of the diaphragm wall . After the concrete pouring of the previous section of the continuous wall is completed, when the concrete is solidified, the joint steel pipe is pulled out. This method is generally used to improve the contact surface of the joint joint and improve the leakage resistance. However, the anti-s...

Problems solved by technology

After the concrete pouring of the previous section of the continuous wall is completed, when the concrete is solidified, the joint steel pipe is pulled out. This method is generally used to improve the contact surface of the joint joint and improve the leakage resistance. However, the anti-seepage effect of the joint joint by the traditional construction method is not good. Ideal, with frequent build quality issues requiring secondary reprocessing
