Waterproof structure of underground diaphragm wall

Abstract

The invention relates to a waterproof structure of an underground diaphragm wall, and belongs to the field of building construction. The lower part of a wall body is provided with mounting pipelines which are obliquely arranged, the vertical interval is 0.1 m, the transverse interval is 3 m, the outer sides of the mounting pipelines are provided with stiffening ribs, and the mounting pipelines are connected with permeation pipelines through built-in threads; the mounting pipeline is welded with a reinforcement cage in an inclined manner of 30-60 degrees; an elastic sliding block is arranged in the mounting pipeline, the reinforcement cage is lowered to the bottom of the underground diaphragm wall, after underground soil on the other side is excavated, the elastic sliding block is taken out, and a hexagonal perforated steel plate, a permeable material and waterproof paint of the pipe wall are arranged at the front end in the permeation pipeline. The waterproof structure is convenient to manufacture, easy to mount, easy to disassemble and maintain and good in economic effect, underground water on one side of the underground wall can be conveniently drained under the condition that the wall is not damaged, and the possibility of seepage at the wall joint due to water pressure is reduced.

Description

technical field [0001] The invention belongs to the field of building construction, in particular to an underground continuous wall waterproof structure. Background technique [0002] The underground diaphragm wall is a kind of trenching machine used on the ground for basic engineering. Along the peripheral axis of the deep excavation project, a long and narrow deep trench is excavated under the condition of mud retaining wall. After the trench is cleaned, it is hung in the trench Then use the conduit method to pour underwater concrete to form a unit groove section. In this way, a continuous reinforced concrete wall is built underground as a water interception, seepage prevention, load-bearing, and water retaining structure, while the underground continuous The waterproof performance of the wall is a very important performance. [0003] The waterproofing of the existing underground diaphragm wall is usually to install waterproof boards on the inner and outer sides of the di...

AI Technical Summary

Problems solved by technology

[0003] The waterproofing of the existing underground diaphragm wall is usually to install waterproof boards on the inner and outer sides of the diaphragm wall, and use the waterproof boards to improve the waterproof effect of the underground diaphragm wall. However, the waterproof boards are easily damaged during construction and are not easy to maintain. Groundwater infiltration at the joints of the underground diaphragm wall still occurs due to excessive groundwater pressure
