Blocking system for water seepage crack of basement wall body and construction method thereof

Abstract

The invention discloses a blocking system for a water seepage crack of a basement wall body and a construction method thereof. The blocking system comprises the wall body with the water seepage crack. A groove is formed in the back water surface of the wall body and in the corresponding position of the water seepage crack. Water guiding pipes for guiding the water seepage in the wall body are horizontally arranged in the groove. One ends of the water guiding pipes abut against the internal water seepage crack and fixed to the wall body through a first layer of crack blocking layer buried at the bottom of the groove. A valve is arranged on the part, outside the first layer of crack blocking layer, of pipe bodies, wherein the valve is in an opening state at the time of water guiding and in a closed state after water guiding. A second layer of crack blocking layer is arranged in the interior, outside the first layer of the crack blocking layer, of the groove. The second layer crack blocking layer buries the water guiding pipes after completion of water guiding and the valve inside the groove, and the groove is filled and leveled up. A waterproof layer is laid outside the second layer crack blocking layer. The blocking system has the characteristics of safety, applicability and the like and has good popularization and practical value, and good economic benefit is produced after wide application and popularization.

Description

technical field [0001] The invention relates to the technical field of civil construction, in particular to a sealing system for water seepage cracks in a basement wall and a construction method thereof. Background technique [0002] With the development of society and the advancement of technology, there are more and more large underground parking lots, shopping malls and civil air defense projects. For a large-scale basement, the length of the wall is often longer, and cracks will inevitably appear on the wall after construction, and cracks are likely to cause water seepage. The traditional process generally adopts the "filling method". The crack is enlarged with a pick, steel brazing or a high-speed rotating cutting disc to form a V-shaped or trapezoidal groove. After cleaning, epoxy mortar or cement mortar and asphalt ointment are applied layer by layer. , polymer sealing materials or various finished plugging agents and other materials to seal cracks. However, when th...
