Hermetically sealing waterproof construction method for basement

Abstract

The present invention discloses a hermetically sealing waterproof construction method for a basement, and relates to the field of building waterproof construction. The method comprises the steps of: successively performing construction of waterproof materials to a base plate, side walls and a top plate for slope excavation underground construction after concrete cushion, the side walls and the top plate are completed, then making waterproof protective layers to prevent waterproof layers from being destroyed when assembling reinforcement subsequently, and finally performing waterproof construction of the top plate. A four-side surrounded waterproof coiled material layer is formed in the basement, every node and seaming positions are ensured to be sealed and firmly bonded by adoption of the hermetically sealing technology, the hermetically sealing waterproof effect is achieved, and leakage is completely prevented.

Description

technical field [0001] The invention relates to the field of building waterproof construction, in particular to a fully sealed waterproof construction method for a basement. Background technique [0002] Although the waterproofing project budget of the basement accounts for only a small part of the construction budget, its role is extremely huge. If the building is not waterproofed, the basement will leak, resulting in unusable space or catastrophic collapse, such as subways, culverts, and civil air defense projects, which 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 ...

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.
