Embodiment Construction

[0039] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0040] A basement waterproof construction process, comprising the steps of:

[0041] S1, clean the base, check the flatness of the base, use cement mortar to smooth the parts with unevenness or large pits, and use a flat shovel to level the foreign objects and laitance that protrude from the wall, and clean them up.

[0042] When filling the pit, first remove the debris inside the pit and wash it with water, then prepare cement mortar, and add sealant to the cement mortar.

[0043] Then knead the mixture into a cone with a size similar to that of the pit, then quickly plug it into the pit with force, and squeeze it tightly around it. After 2-3 minutes after curing, let it go to fill the pit.

[0044] Then the moisture content of the surface of the base layer is tested. When the moisture content of the base layer is detected, a 1 square meter coiled material ...

Abstract

The invention discloses a waterproof construction process for a basement, and relates to the field of building construction. The waterproof construction process for the basement comprises the following steps of S1, cleaning a base layer; S2, performing corner treatment; S3, conducting primer coating; S4, trial laying of a coiled material; S5, heating the surface of the coiled material; S6, pavingand pasting the coiled material; S7, scraping and sealing an interface; S8, pasting lap seams; and S9, constructing a protective layer. The waterproof construction process for the basement has the following advantages that cement mortar is made into a circular arc or a 135-degree break angle at the corner position, so that the waterproof coiled material can be flatly attached to the surface of thebase layer, the phenomena of hollowing and wrinkling are avoided, perfect sealing of all positions is achieved, and the waterproof effect of the whole basement is improved.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a basement waterproof construction process. Background technique [0002] A basement is a room in a building that is below the outdoor ground. Building a basement below the ground floor of a house can improve the efficiency of building land use. The foundations of some high-rise buildings are deeply buried, and making full use of this depth to build basements has good economic and practical effects. [0003] Chinese patent CN108532646A discloses a basement waterproofing construction method, which includes the following steps: S1 excavating a trench; S2 building a guide wall along the inner wall of the trench; S3 laying a base waterproof membrane in the trench; S4 erecting a formwork, pouring Diaphragm wall; S5 remove formwork; S6 lay façade waterproof membrane overlapped with base waterproof membrane on the outside of diaphragm wall. [0004] When adopting the above-mention...
