Anti-seepage structure of kitchen and bathroom reserved hole and construction method

Abstract

The invention relates to anti-seepage structures of building engineering, in particular to an anti-seepage structure of a kitchen and bathroom reserved hole and a construction method. The anti-seepage structure of the kitchen and bathroom reserved hole comprises the pipeline reserved hole formed by cast-in-place concrete, a drain pipe and filling concrete poured between the pipeline reserved hole and the drain pipe are arranged in the pipeline reserved hole, the filling concrete is composed of a first concrete layer and a second concrete layer, the first concrete layer is located below the second concrete layer, the first concrete layer is in a straight cylinder shape, and the second concrete layer is in an inverted-circular-cone shape. The two concrete layers in different shapes are combined, so that the combination area with the pipeline reserved hole (1) is enlarged, and the anti-seepage performance of the plugged hole is improved. Thus, maintenance cost increased by water leakage can be reduced, and resources can be easily saved. An anti-seepage agent is arranged in the filling concrete, and thus the anti-seepage effect is better.

Description

technical field [0001] The invention relates to an anti-leakage structure for construction engineering, in particular to an anti-leakage structure for a reserved hole in a kitchen and bathroom and a construction method for realizing the structure. Background technique [0002] At present, after installing drainage pipes in the reserved openings of cast-in-place concrete floors in kitchens and bathrooms, it is easy to leak water near the drainage pipes. The leakage problem has always been a common quality problem that has not been completely eradicated. Leakage in reserved holes is a building leakage problem. This is a major phenomenon of leakage, and it is also an urgent problem to be solved. Contents of the invention [0003] The object of the present invention is to provide an anti-seepage mechanism and construction method for the reserved hole in the kitchen and bathroom, so as to avoid water leakage after installing the drain pipe in the reserved hole of the concrete f...
