Abstract

The invention provides a construction method for treating water leakage of a wall joint of a ground connecting wall, which comprises the following steps of: S1) from two sides of the wall joint of theground connecting wall with water leakage to a given distance, constructing a plurality of grouting holes with given depths according to a given distance, wherein each grouting hole obliquely penetrates through the wall joint according to a given included angle with the wall joint and intersects with the wall joint in the depth direction of the wall joint; S2) embedding a grouting nozzle into each grouting hole; S3) injecting double-liquid slurry from any grouting nozzle through a grouting machine, and sealing all the grouting nozzles except for the grouting nozzles for injecting the double-liquid slurry when the double-liquid slurry comes out form each grouting hole, continuously grouting until the grouting machine cannot pump the double-liquid slurry, and stop grouting; S4) after the double-liquid slurry solidifies, removing all the grouting nozzles and completing the leakage treatment of the wall joint of the ground connecting wall. According to the construction method, the water leakage position is accurately blocked according to the water leakage position of the ground wall joint, so that the problems of overhigh blocking cost and blocking waste in the prior art can be solved.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a construction method for water leakage treatment of joints between ground and walls. Background technique [0002] In the process of building construction, the cracks on the building wall are one of the most common diseases of concrete buildings. Some serious cracks not only endanger the stability of concrete buildings, but also cause water leakage. With the rapid advancement of my country's infrastructure construction, there are more and more deep foundation pit projects. For deep foundation pits with high groundwater levels, especially in confined water strata, ground wall enclosure structures are often used, which are subject to geological conditions, construction process control, etc. Affected by various factors, the risk of water leakage from the ground connection wall of deep foundation pits caused by pressurized water increases, especially when cracks appear on the wal...
