Embodiment 1

[0022] A concrete ground waterproof and plugging construction method, comprising the steps of:

[0023] (1) Cut a V-shaped groove with a depth of 4cm at the leakage position, and clean the base layer to ensure no dust, no loose particles and no grease;

[0024] (2) Dilute the first additive with pure water at a weight ratio of 1:1, then mix the diluted mixed water with the plugging agent at a weight ratio of 1:0.5, stir for 3-5 minutes, and mix the resulting mixture Fill to the bottom of the V-shaped groove, the filling thickness is 0.4-0.5cm;

[0025] (3) Mix the first additive with pure water at a ratio of 1:3 by weight, then mix the diluted mixed water with the plugging agent at a ratio of 1:0.8 by weight, stir for 5-10 minutes, and then fill the mixture to In the V-shaped groove, compact and hold the pressure for 3 minutes, and the filling thickness is 1cm;

[0026] (4) After 12 hours, when the surface is dry and there is no obvious water vapor leakage, mix the second ad...

Abstract

The invention discloses a concrete ground water prevention and leakage stoppage construction method. The method fills the leakage stoppage material at a leakage place at three times, and the composition and the proportion of a first additive, a second additive, a leakage stoppage agent and powder adopted are disclosed. The construction method is good in leakage stoppage effects and excellent in anti-leakage performance.

Description

technical field [0001] The invention relates to the technical field of building leak plugging, in particular to a construction method for waterproof leak plugging on a concrete floor. Background technique [0002] The waterproof function of a building is an important indicator that reflects the function of the building after it is completed. A good building should not experience water seepage within the waterproof warranty period after the completion of the project. As a common defect in engineering quality, the building Water seepage problems are not uncommon in houses handed over after the completion of the project. The leakage rate of residential buildings remains high. The problem of building leakage has caused great troubles to people's daily life. What is more serious is that it has affected the safety and use of the overall structure of the house, causing great hidden dangers to personal and property safety. . With the acceleration of the urbanization rate, the numb...
