Embodiment Construction

[0017] As shown in the figure, it is a construction method for installing a copper sheet water stop between an underground connected wall and a concrete floor, which includes the following steps in sequence:

[0018] 1) Construct the underground conjoined wall 1, and then carry out earthwork excavation to expose the inner wall of the underground conjoined wall 1, and excavate the installation groove of the water stop at the position where the water stop is required on the wall; the depth of the installation groove of the water stop is 6~7cm, limited to not destroying the protective layer of the steel bar, the height of the installation groove of the water stop is 12~15cm;

[0019] 2) After cleaning the inside of the installation groove of the waterstop with high-pressure air, paint the bottom of the groove with epoxy resin paint to form a primer layer of epoxy resin paint 5;

[0020] 3) After the epoxy resin coating primer 5 can be drawn, apply epoxy cement on the upper side o...

Abstract

The invention relates to a copper sheet post-embedding type water stop construction method of an underground waterproof project, and belongs to the field of construction of underground projects. The method comprises the following steps of firstly chiseling a water stop part mounting groove in a built concrete structure; coating epoxy coating at the bottom part of the groove as a bottom layer; coating epoxy grout, and then fixing the copper sheet water stop part; coating epoxy mortar on the copper sheet water stop part, and filling the water stop part mounting groove with epoxy mortar; after initial curing, coating an epoxy resin coating layer at the surface of the epoxy mortar; after curing, detaching a bracket, casting the adjacent structure requiring water stopping, embedding the other side of the copper sheet water stop part in the concrete of the adjacent structure, and enabling the bending part of the copper sheet water stop part to be remained in an expansion joint. The method has the advantages that the method is used for the construction of reverse type underground waterproof projects, the sealing and waterproof effects are good, and the same sealing and waterproof effects as those of the pre-embedding method are realized.

Description

technical field [0001] The invention relates to a construction method of an underground project, in particular to a water-stop construction method of an underground waterproof project. Background technique [0002] In the construction of existing water conservancy or other underground waterproofing projects, the adjacent structures are all embedded with copper sheets to stop water. The currently known construction methods are all "pre-embedded methods", that is, half of the copper sheets are pre-embedded before concrete pouring. , The other half is reserved as a method for connecting adjacent structures. Using the "pre-embedded method" construction requires excavation first, and the excavation operation will cause adverse effects on the surrounding foundations and cause problems such as uneven settlement of surrounding buildings; in order to overcome this problem, there is also a reverse The method of construction is to drill holes of a certain depth from the ground first, ...
