Problems solved by technology

[0002] Because the underground project is buried deep in the ground, it is always subject to the infiltration of groundwater. If the waterproof problem is not handled properly, the groundwater will seep into the interior of the building or the building body, which will bring a series of problems: such as affecting the work and life of personnel; Accelerate the rate of building corrosion and shorten the service life
[0004] However, the common practice of overlapping parts of different waterproof materials in existing underground projects has the following defects: ①The materials of the waterproof layer of the side wall and the waterproof layer of the roof are incompatible, so that the waterproof layer of the side wall cannot be overlapped with the roof to form a closed waterproof; ②The side wall The overlapping parts of the waterproof layer and the roof waterproof layer are not well treated, which may easily lead to water leakage; ③The waterproof material of the roof cannot be well integrated with the roof, which is easy to channel water, resulting in water leakage from the roof

Embodiment 1

[0031] The method for overlapping the different waterproof materials of the basement side wall and the planting roof provided in this embodiment comprises the following steps:

[0032] 1) see figure 1 As shown, the anti-sagging MPU polyurethane waterproof coating is applied to the side wall 1 multiple times to form a 2.0mm thick side wall waterproof coating film 3, and the coating film extends to the top plate 2 through the joint between the side wall 1 and the top plate 2 , the width of the coating film extending to the top plate 2 is 150mm;

[0033] 2) In step (1), after the last pass of anti-sagging MPU polyurethane waterproof coating is applied, when the last pass of the coating is not cured, the joints of side wall 1 and roof 2 are respectively along the length direction of side wall 1 and roof 2 Spray clean medium-fine sand on the side wall waterproof coating film 3 on both sides of the male corner to form a sand layer 5, and the range of sandblasting is within 150mm fr...

Embodiment 2

[0038] Repeat the test with the method of Example 1. After testing, the bonding strength between the roof waterproof coiled material 6 and the roof waterproof coating film 4 at the lap joint and the side wall waterproof coating film 3 reaches 2.2 MPa, and the side wall is waterproof. The coating film 3, the roof waterproof coating film 4 and the roof waterproof coiled material 6 can form a long-term effective sealing waterproof layer.

Abstract

The invention relates to a method for overlapping different waterproof materials of a side wall and a roof, comprising: coating a side wall waterproof paint on the side wall to form a side wall waterproof coating film and extending to the roof; when the side wall waterproof paint is not cured, On the side wall waterproof coating on both sides of the connection between the side wall and the top plate, sand grains are laid along the length direction of the side wall and the top plate to form a sand layer; On the side walls, the roof waterproof coating film is covered on the sand layer, wherein the roof waterproof coating is non-cured rubber asphalt waterproof coating; the waterproof membrane is laid on the roof and extended to the side wall, and the waterproof membrane is covered on the roof waterproof on the film. This method can effectively bond the incompatible side wall waterproof coating and roof waterproof coating together, and has high bonding strength, and also solves the problem of incompatibility between the side wall waterproof coating and the roof waterproof coating due to different materials , to avoid leakage problems caused by a long time.

Description

technical field [0001] The invention belongs to the technical field of structural waterproofing, and in particular relates to a method for overlapping different waterproofing materials of a side wall and a top plate. Background technique [0002] Because the underground project is buried deep in the ground, it is always subject to the infiltration of groundwater. If the waterproof problem is not handled properly, the groundwater will seep into the interior of the building or the building body, which will bring a series of problems: such as affecting the work and life of personnel; Accelerate the rate of building corrosion and shorten the service life. [0003] According to the national standard "Technical Specifications for Waterproofing of Underground Engineering" GB50108-2008, fully enclosed and partially enclosed waterproof and drainage designs should be adopted for single-building underground projects. Forms a closed waterproof layer. The overlapping length of the join...
