Full-seal waterproof construction method for side wall and engineering top face

Abstract

The invention discloses a full-seal waterproof construction method for a side wall and an engineering top face, and relates to the field of building waterproof construction. The method comprises the steps that (1), leveling treatment of a building envelope is carried out; (2), waterproof rolls are laid, wherein the waterproof rolls are fixed to the side wall through a temporary fixing method; (3), joints are strengthened; and (4), a waterproof protection layer is made. The waterproof rolls are waterproof rolls capable of generating the chemical crosslinking reaction and the physical mortise and tenon function with cast-in-place concrete. Sealant is waterproof sealant capable of being in chemical crosslinking reaction and physical mortise and tenon cooperative binding with cement or concrete. According to the operation and construction characteristics of the side wall of underground engineering, the method of fixing the waterproof rolls in advance and then pouring side wall concrete to be bound with the waterproof rolls is adopted, bonding of large-area rolls is ensured, seamless bonding of each joint and each seam is ensured through the full-seal technology, and the waterproof effect of full-seal water prevention and leakage eradication is achieved.

Description

technical field

[0001] The invention relates to the field of building waterproof construction, in particular to a fully sealed waterproof construction method for side walls and engineering top surfaces. Background technique

[0002] Waterproof construction is of great significance to underground engineering. If the waterproofing is not done properly, the basement will leak. In severe cases, the space will be unusable or catastrophic collapse, such as subways, culverts, and civil air defense projects, will cause huge losses. With the rapid development of the basic construction industry, the development and application of building waterproof engineering technology and various waterproof new materials and new processes are also emerging. However, there are still some problems in the current waterproof system, which lead to the failure of waterproofing. The specific reasons are:

[0003] 1. The waterproof effect of the waterproof membrane is not good

[0004] First of all, the...

[0043] Construction of a tunnel in Nanning City, Guangxi, in October 2013. There are yin and yang corners, gutters, deformation joints, construction joints, wall pipes and other nodes on the construction site. The Chinese patent product that was applied for and authorized on October 9, 200910114456. No. is the sealing paste in CN201210446557.9.

[0044] Firstly, the enclosure structure is leveled, and the underground engineering enclosure structure is leveled by methods such as shotcrete, cement mortar or brick walls;

[0045] Then pre-lay the waterproof membrane on the side wall and top surface of the tunnel. When laying a section or a piece of double-sided adhesive waterproof membrane, the composite nailing method is used to stick a gasket on the surface of the waterproof membrane, and then use the injection The nail gun shoots nails into the sealing gasket and waterproof membrane, and fixes them on the top surface or side wall of the project, so that the waterproof membran...
