Method used for underground construction side wall and bottom plate water seepage treatment

Abstract

The invention discloses a method used for underground construction side wall and bottom plate water seepage treatment. The method includes the following steps that side wall and bottom plate cracks are subjected to leakage blocking, and then thorough cleaning is conducted; a water conveying plate is comprehensively laid on a cleaned side wall and a cleaned bottom plate, and the water conveying plate communicates with a draining system of the underground construction; and a concrete layer is poured on the laid water conveying plate in a covering manner. By means of the method, leakage blockingis firstly conducted on water leakage positions of the cracks on the side wall and the bottom plate firstly, and the water discharging amount of the cracks can be greatly reduced; the water conveyingplate is arranged on the side wall and the bottom plate so that seeping water between the water conveying plate and the side wall and between the water conveying plate and the bottom plate can be discharged through the draining system of the underground construction; the concrete protection layer is poured on the water conveying plate in the covering manner, and the water conveying plate is prevented from being damaged in the use process; and by means of the method, the side wall and bottom plate water seepage problem is dealt with in a blocking and conveying draining combined manner, and therefore water seepage parts can be isolated, and water leaking accidents are prevented from happening to the underground construction.

Description

technical field [0001] The invention relates to the field of concrete construction, in particular to a water seepage treatment method for side walls and bottom plates of underground engineering. Background technique [0002] In order to develop and utilize underground space resources, people have built underground projects such as underground houses, underground railways, highway tunnels, underwater tunnels, underground common trenches and underpasses for crossing streets. In underground engineering construction, concrete pouring is often carried out in order to isolate the underground space from the original formation. When cracks appear in the concrete side wall and bottom plate during later use, since the outside of the side wall and bottom plate are stratum soil, which has relatively rich groundwater, groundwater will penetrate into the underground project through the cracks in the side wall and bottom plate , causing water leakage accidents in underground works. For t...
