Fully sealed waterproof construction method for side wall and project top surface

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...

AI Technical Summary

Problems solved by technology

[0008] In terms of waterproof and anti-seepage construction of tunnels, subway basements, garage roofs, civil air defense projects, side walls or top surfaces of dams and culverts, laying ordinary waterproof membranes only has physical adsorption and mortise and tenon interactions with the construction base surface. Under the action of the gravity of the coil itself, it is easy to cause the coil to fall off, making the waterproof failure

The existing method is to set a suspender on the coil, use the suspender to connect and fix it on the top of the tunnel, and then pour the secondary lining concrete, but this makes the structure of the coil complicated and the construction is not easy

[0009] Therefore, the construction of the waterproof layer on the top or side walls of tunnels and subway basements is very difficult, and the waterproof layer is also easily damaged, resulting in water leakage.
