Concrete wall construction joint waterproof treatment method

Abstract

The invention relates to a concrete wall construction joint waterproof treatment method which comprises the steps of (1) cleaning a wall, (2) laying a first layer of waterproof coiled material, (3) laying a second layer of waterproof coiled material, (4) laying a third layer of waterproof coiled material and (5) attaching an outer protective layer. Compared with the prior art, the method has the advantages that a mode of stacking multiple layers of coiled materials is adopted, so that wall construction joints with a waterproof requirement are effectively protected, and an underwater leakage phenomenon caused by failure of waterproof measures is avoided; the waterproof coiled materials are not attached to a basic layer within a range and properly reserve expansion amount, so that the ability of a waterproof layer adapting to basic layer deformation is improved, and the waterproof coiled materials are prevented from being bumpy and cracking; the protective layer is additionally disposed outside the coiled materials, so that construction portions are protected from underground water or erosion of corrosive matter; the method is easy and convenient to operate, and people only need to operate according to conventional construction methods.

Description

technical field [0001] The invention relates to the technical field of waterproof treatment in building construction, in particular to a waterproof treatment method for construction joints of concrete walls. Background technique [0002] When constructing a box foundation or a basement, the concrete of the bottom slab and the outer wall slab are poured and tamped separately, and there is a construction joint in the section of the wall slab concrete poured twice. When the position of this joint is below the groundwater level line, Water seepage is easy to occur, so the construction joints must be waterproofed. There are many ways to deal with it. At present, the more common method is to install water-stop steel plates or water-stop strips in the waterproof concrete wall, and at the same time lay a layer of waterproof membrane or paint a layer of penetrating crystal waterproof material on the outer wall. In this construction method, only one waterproof measure is provided on ...

AI Technical Summary

Problems solved by technology

In this construction method, only one waterproof measure is installed on the facing surface of the wall. Under the long-term immersion and corrosion of groundwater, or due to the joint action of uneven settlement of buildings and soil freezing and thawing, once the waterproof membrane cracks or waterproofs If the coating fails, it will lead to waterproof damage and groundwater leakage. Groundwater leakage into the project will accelerate the corrosion of the interior decoration and equipment of the project and affect the normal use of building products. It takes a lot of money to use machinery to remove the leaking water inside the project. A lot of energy and money
