Design of settlement joint provided inside underground continuous wall and construction method thereof

Abstract

The invention relates to a settle joint design of an underground continuous concrete wall and the construction method, wherein the settle joint is vertically positioned in the underground continuous concrete wall and divides the steel reinforcement cage in the underground continuous concrete wall into the left part and the right part; non-uniform settlement can be produced in the underground continuous concrete wall on both sides of the settle joint; the settle joint comprises two parallel common length abnormal steel plates with a spacing from 80 mm to 100 mm; a waterproof fiberboard soaked with asphalt is arranged between the two common length abnormal steel plates and three rubber waterproof belts are arranged on the vertical plane of the two common length abnormal steel plates. The construction methods are simple and universal, comprising working procedures of welding, arranging, hanging and casting the common length abnormal steel plates and the parts with the steel reinforcement cage. The settle joint design of an underground continuous concrete wall has the advantages that the construction of the joint can be carried out synchronously with the construction of the major body of a building, preventing delayed completion of preset joint, which not only provides convenience for construction but also reduces the construction cycle; at the same time the three rubber waterproof belts avoids the problem of water seepage and infiltration.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a design of a settlement joint arranged in an underground continuous wall and a construction method thereof. Background technique [0002] In high-rise buildings, due to the needs of function and shape, the high-rise main building is often connected with the low-rise podium, and the podium surrounds most of the main building. The uneven settlement between the high-rise main building and the low-rise skirt room in a high-rise building is a problem that has plagued construction for a long time. In order to solve the settlement difference between the high-rise main building and the low-rise skirt room, it is usually Seams are reserved between the high-rise main building and the low-rise podium (the "seam" is very wide, also known as post-casting tape), that is, after the main structure of the entire building is completed for a period of time, usually about one year, the high-ris...

However, this method has a long construction period, and the concrete pouring at the post-casting zone needs to be carried out two to three months aft
