Waterproof outer wall and construction method

Abstract

The invention relates to a waterproof outer wall and a construction method. The waterproof outer wall comprises a wall body and a grouting device. The bottom end of the grouting device penetrates through the backfill soil and extends to the exterior of the backfill soil, the top end of the grouting device is buried in the wall body, a grouting opening of the grouting device penetrates through the wall body and extends to the exterior of the wall body, and the grouting device is used for leaking stoppage of a later leakage area; a combed joint is arranged on one side, facing outdoors, of the wall body, and the combed joint is arranged at a construction joint between the wall body and the bottom plate; the construction process comprises the steps of pre-burying a grouting device, reserving combed joints, pouring cushion layer concrete and joint layer concrete, laying a waterproof layer and pouring bottom plate concrete. On one hand, the grouting device is arranged, leakage stoppage is conducted on the construction joint in the later stage in the mode that the grouting device sprays and grouts, and therefore manpower and material resources generated by later reworking are reduced; and on the other hand, the combed joints are arranged on the wall body, so that the water seepage path is effectively increased, the water seepage probability is effectively reduced, and the water resistance of the wall body is improved.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a waterproof exterior wall and a construction method. Background technique [0002] At present, the waterproofing of basement walls is a partial waterproofing project to ensure that the structure of the building is not invaded by water and the interior space is not harmed by water. The exterior wall waterproofing project occupies an important position in the entire construction project. [0003] The exterior wall waterproofing project involves many exterior wall structures such as the basement exterior wall of the building and the exterior wall of the house. Corrosion, to ensure that the building structure and internal space are not polluted, and provide a comfortable and safe living environment for people. Generally, the waterproofing project of building external walls adopts the structure of setting waterproof layer on the outer side of the external wall. ...

AI Technical Summary

Problems solved by technology

[0004] However, when the waterproof layer is installed on the outside of the outer wall, many buildings still have local water seepage on the outer wall. When reworking and plugging leaks in the later stage, a lot of manpower is added, which reduces the construction efficiency and prolongs the construction period.
