Underground outer wall construction joint water-stopping structure and construction method thereof

Abstract

The invention discloses an underground outer wall construction joint water-stopping structure and a construction method of the underground outer wall construction joint water-stopping structure. The underground outer wall construction joint water-stopping structure comprises water-stopping steel plates, the water-stopping steel plates are vertically buried in the middle position of a horizontal construction joint along the length direction of an outer wall, each water-stopping steel plate is formed by bending an entire steel plate and is divided into an upper part and a lower part in the vertical direction along the horizontal construction joint, each upper portion is provided with a reverse U-shaped right-angle bent hook which exposes out of the upper surface of the horizontal construction joint and is bent towards one side of a water-facing surface, each lower portion is provided with an inclined bent edge which is embedded in outer wall pre-poured concrete, is bent towards one side of the water-facing surface, and a water expansion water-stopping strip is filled in each right-angle bent hook. The water-stopping steel plates are connected into a whole along the length direction of the outer wall, every two adjacent water-stopping steel plates are connected in an abutted welding mode, and a connector water-stopping connection steel plate is sleeved and overlapped in the middle of the outer side of the abutted welding joint, and the shape of the connector water-stopping connection steel plate is the same as that of the water-stopping steel plates in full welding. The underground outer wall construction joint water-stopping structure and the construction method resolves the problems that a traditional steel plate water-stopping belt is short in water seepage length along the steel plates and short in water seepage time along the water-facing surface, water leaks easily, the construction quality is not easy to control, and the later period use is affected.

Description

technical field [0001] The invention relates to a waterproof structure and a construction method for construction joints of basement exterior walls during construction engineering construction. Background technique [0002] At present, the water stop of the construction joints of the underground external wall in the construction of the building generally adopts a single-layer steel plate water stop. If it is not handled properly, water seepage will often occur, and the construction quality will not be easy to control, which will affect the later use. [0003] The joints of single-layer steel plate waterstops generally use lap joints, and sometimes lap welding is also used. However, as the water seepage time increases, it is possible to bypass the steel plate waterstop along the steel plate, causing water seepage at the construction joints, which directly affects the later stage. use. [0004] At present, the soil quality, particle size and backfill quality of the backfill ...
