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

Embodiment 1

[0048] The construction of a tunnel in Nanning City, Guangxi, started in November 2013. After the concrete cushion and protective wall were completed in the underground project of sloping excavation, the construction was carried out with a fully sealed waterproof construction method. The waterproof membrane used was the application for this application. The Chinese patent product that was applied for on October 9, 2009 and has been authorized, the waterproof membrane in the patent application number 200910114456.X; the node sealing paste used is the Chinese patent application submitted by the applicant on November 10, 2012 , the application number is the sealing paste in CN201210446557.9. Carry out construction according to the following construction sequence:

[0049] The treatment of the base surface: the concrete base surface is repaired and leveled, the garbage is cleaned and watered to moisten, and the inner and outer corners are filled with cement mortar to form obtuse o...

Embodiment 2

[0059] The construction of a tunnel in Guangxi, started in May 2014, is a slope excavation underground project. After the concrete cushion and protective wall are completed, the waterproof construction method of the basement is fully sealed. The waterproof membrane used is the applicant's The Chinese patent product that was applied for on October 9, 2009 and has been authorized, the waterproof membrane in the patent application number 200910114456.X; the node sealing paste used is the Chinese patent application submitted by the applicant on July 3, 2013, The application number is the sealing paste in CN201310276909.5.

[0060] The treatment of the base surface: the concrete base surface is repaired and leveled, the garbage is cleaned and watered to moisten, and the inner and outer corners are filled with cement mortar to form obtuse or rounded corners; the repair agent used is a mixture of cement and water in a weight ratio of 2.5:1 The cement slurry is then prepared by adding...

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 ...
