Underground building water-proof structure with fabricated temporary protective wall, construction method and building

Abstract

The invention belongs to the field of water-proof technical devices of underground building corners and particularly relates to an underground building water-proof structure with a fabricated temporary protective wall, a construction method and a building. The underground building water-proof structure comprises a cushion layer used for protecting a structural base plate and laid on a ground foundation; the border of the cushion layer is provided with a border guide wall, and the border guide wall is provided with the temporary protective wall which is used for supporting pouring of concrete and dismantled after pouring is completed; internal corners used for surrounding the underground building corner are constituted through matching of the cushion layer and the border guide wall, and elastic water-proof felts are installed in the internal corners; the cushion layer is covered with one ends, used for paving, of the elastic water-proof felts, and the other ends of the elastic water-proof felts extend between the border guide wall and the temporary protective wall and are fixed to the upper surface of the border guide wall; a structural wall is installed on the upper side of the cushion layer, and the structural wall comprises the structural base plate installed on the upper sides of the elastic water-proof felts and structural side walls installed on the inner side of the temporary protective wall; and the structural base plate and the structural side walls are connected into a whole, and connecting external corners of the structural side walls and the structural base plate correspond to the internal corners where the cushion layer and the border guide wall are connected.

Description

technical field [0001] The invention belongs to the technical field of underground building bottom and wall corner waterproofing, and in particular relates to an underground building waterproof structure with an assembled temporary protective wall, a construction method and a building. Background technique [0002] At present, in the building construction process, it has always been a difficult problem to waterproof the external corners of the underground building, especially the waterproofing of the external corners of the connection between the bottom plate and the side wall of the underground part. At present, in the process of casting or building side walls and bottom surfaces, brick walls are generally used for enclosure and function as retaining walls. The post-fill brick wall is also used as an outer protective structure in the waterproofing construction. For the waterproof layer, improper design or incorrect operation of the brick wall, scratches and punctures of th...

AI Technical Summary

Problems solved by technology

In the underground engineering system, the mutual stress between the brick permanent guide wall and the structural side wall is relatively large, resulting in the largest structural deformation at the lap joint between the structural side flagpole and the structural bottom plate, and structural damage is most likely to occur, which directly affects the waterproofing. Function

Compared with the concrete structural side wall, the protective effect of the brick protective wall is not great, and its bricks are easy to loosen under external force, and collide with the waterproof layer to damage the waterproof

Moreover, the use of masonry brick walls increases economic investment and increases working hours, which is inconsistent with the current advocacy of greening and environmental protection, high efficiency and energy saving
