Obstructing and water retaining method for residential waterproof construction

Abstract

The invention discloses an obstructing and water retaining method for the residential waterproof construction, which is used for the waterproof construction of the residential housing and sequentially comprises the following steps of: A, constructing a sand bank; B, carrying out closed-water test; C, caulking and repairing the sand bank; D, pouring a concrete cushion layer; E, tunneling the sand bank; F, coating an interface adhesive; and G, constructing a waterproof dam, i.e. pouring anti-leakage fine-stone concrete into a groove, prying up pipelines in the groove one by one to mainly tamp the concrete below the pipelines, simultaneously mainly tamping the concrete at corners of the bottom inside the groove, then continuously pouring the anti-leakage fine-stone concrete until the groove is full, tamping, screeding and finishing constructing the waterproof dam. Due to the adoption of the obstructing and water retaining method, the water environment and the dry environment of the residential housing can be separated, a transverse overflow passage between the water environment and the dry environment is intercepted, the waterproof quality is improved, the cost of the waterproof construction is also obviously reduced, and the construction period is shortened.

Description

technical field [0001] The invention relates to a building waterproof construction method, in particular to a partition water blocking method for residential waterproof construction. Background technique [0002] With the development of the times and the gradual improvement of people's quality of life, the heating mode of winter heating areas in northern China, northeast China, and northwest China has gradually transitioned from traditional radiator heating to floor heating heating, and the laying of floor heating pipelines is Waterproofing construction brings a new twist. In order to adapt to the new situation, two layers of polyurethane waterproof coatings are often used in the waterproofing of residential kitchens and bathrooms: the first layer is polyurethane bottom layer waterproofing, which is located on the cement mortar leveling layer at the bottom of the kitchen and bathroom floor; the second layer is polyurethane surface layer waterproofing, laying After the floor...

AI Technical Summary

Problems solved by technology

[0004] ① Poor waterproof effect: a loose "through layer" with an elevation of 50-100mm is formed between the first and second waterproof layers

[0005] ②High project cost: two layers of polyurethane waterproof construction on the bottom layer and the surface layer, plus two layers of cement mortar leveling layer construction, plus two layers of cement mortar protective layer construction, the cost is very high;

[0006] ③ Long construction period: The construction process is cumbersome and complicated, and organic polyurethane materials cannot be wet-worked, resulting in delays in the construction period and a long construction period

[0007] Chinese patent 200910259429.1 discloses a "Low Temperature Radiant Floor Heating Toilet Waterproof Threshold Waterproof Construction Method". Although the waterproof construction process of setting a watertight threshold at the door of the kitchen and bathroom is adopted, it still uses the traditional waterproof construction method, which is complicated. , the cost does not fall but rises, the construction period does not shrink but increases, and the actual application value is not high

At the same time, in the process of building the water-stop threshold, it adopts the method of one-time construction and molding. This method is prone to leakage at the pipeline passing through the water-stop threshold. Once leakage occurs, the water-stop threshold will completely lose its waterproof value. , the floor must be dug out and re-constructed
