Embodiment Construction

[0019] The specific implementation process of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0020] A kind of waterproof structure outside the underground laminated wall, such as Figure 1-3 As shown, it includes a parapet wall 1 and a side wall 7 , and the side wall 7 is arranged inside the parapet wall 1 .

[0021] Such as figure 1 and image 3 As shown, firstly, leveling and basic water-stop treatment are carried out on the completed parapet wall 1 according to the regulations, and the leveling and basic water-stop treatment are carried out according to the relevant construction acceptance specifications of parapet piles and diaphragm walls respectively; The pre-laid anti-adhesive roll material 3 is laid to the superposition of the side wall 7 and the parapet wall 1, and the pre-laid anti-adhesive roll material 3 is not less than 0.7mm thick PE film composited with a height of not less than 0.5mm thick Molecular f...

Abstract

The invention discloses an underground composite wall external water-proofing structure. The structure adopts concrete mixed with cement-based permeated crystal waterproofing agent, and is applied to a side wall and a floor slab at the composite place, and forming not less than 200 mm overlap joint with a pre-paved (anti-sticky) coiling material paved and hung on the side wall before, and thereby the continuous external water-proofing is realized. The underground composite wall external water-proofing structure solves project difficulties existed all the time by a simple technology, and is not only applicable to deep and shallow basements incapable of performing external water-proofing work but also to a composite wall of a subway.

Description

technical field [0001] The invention belongs to the technical field of building waterproofing, and in particular relates to a waterproof structure outside laminated walls of underground engineering. Background technique [0002] In areas with dense urban buildings and structures, the construction of underground projects requires that the side walls (or inner lining walls) be constructed close to the parapet walls, so that the external waterproofing can only be done with pre-laid (anti-adhesive) coils. The waterproof layer has to be disconnected at the place where the side wall and the retaining wall need to be superimposed, resulting in local weakness. The waterproofing cannot be solved by simply painting and penetrating the crystalline waterproof coating, because the coating should be directly applied to the concrete structure body. , and here can only be painted on the parapet wall. [0003] The retaining walls of deep foundation pits, whether continuous walls or retainin...
