Description

Water stopping wall for tunnel excavation

Technical Field

The utility model is suitable for the technical field of tunnel excavation assistance, and particularly relates to a water stop wall for tunnel excavation.

Background

At present, during tunnel construction, underground water easily flows into a construction area, and then a corresponding water stop wall is needed to be used for plugging and draining the underground water.

According to a patent (publication number is 'CN 211924193U'), the outer wall of the right side surface of the water-stopping wall is fixedly connected with a soil-retaining cover, the inside of the soil-retaining cover is movably connected with a mounting plate, the upper surface of the mounting plate is provided with a through groove, the inside of the through groove is respectively and fixedly connected with a filter screen and a filter plate, and the filter screen is positioned below the filter plate; the inside fixedly connected with overflow pipe of retaining wall cover, the one end of overflow pipe runs through the stagnant water wall and extends to the outside of retaining wall cover, and the other end sets up in the mounting panel top. According to the water stop wall for tunnel excavation, the mounting plate is arranged in the retaining cover, so that the retaining cover can effectively block soil, silt is precipitated under the action of self gravity, water flow which is precipitated with the soil sequentially passes through the filter screen and the filter plate and then enters the retaining cover, the filter screen and the filter plate can effectively filter impurities which cannot be precipitated in the water flow, and the impurities are prevented from entering the overflow pipe.

However, there are still some disadvantages in the above patents: because block drainage to the filter screen surface of below with groundwater at the use stagnant water wall and carry out when earth filters, because groundwater is inside can adulterate a large amount of silt, and then lead to the filter screen surface to pile up a large amount of silt fast, thereby in order to guarantee the filter screen to the filtration quality of drainage water, need the operator in time quick scrape the clearance to it, thereby increase personnel's labour consumption, one denier clearance is not timely moreover, very easily leads to silt to block up the filter screen and influence the circulation of drainage water. Therefore, we propose a water stop wall for tunnel excavation.
