Novel underground diaphragm wall and construction method thereof

Abstract

The invention relates to a novel underground diaphragm wall and a construction method thereof. A novel underground diaphragm wall body is divided into a supporting section and an embedding section, wherein convex bodies are arranged on the two sides of the embedding section wall body at intervals; and convex bodies are arranged on the soil facing surface of the supporting section wall body. The novel underground diaphragm wall is suitable for a two-wall-in-one type underground diaphragm wall, the depth of a traditional two-wall-in-one type underground diaphragm wall can be effectively reduced,and meanwhile, the settlement of the wall body can be effectively controlled.

Description

technical field [0001] The invention relates to the technical field of underground engineering, in particular to a novel underground diaphragm wall and a construction method thereof. Background technique [0002] Diaphragm wall is a commonly used construction technology in the field of underground engineering. It is often used for ultra-deep underground space enclosure construction, and also for underground space construction in complex environments or key protection areas. It mainly has the functions of water interception, seepage prevention, and soil retaining. . It has the advantages of high safety and good ability to control deformation, but it also has the disadvantages of high cost and high site requirements. [0003] The underground diaphragm wall in the form of "two walls in one" not only has the functions of water interception, seepage prevention, and soil retaining, but also has load-bearing requirements. The traditional "two walls in one" underground diaphragm wa...

It has the advantages of high safety and good deformation control ability, but it also has the disadvantages of high cost and high site requirements.

[0003] The underground diaphragm wall in the form of "two walls in one" not only has the functions of water interception, seepage prevention, and soil retaining, but also has load-bearing requirements. The traditional "two walls in one" underground diaphragm wall adopts ultra-deep wall width at the bottom The hard bearing layer is used to solve the problems of load bearing and settlement, but it also brings about an increase in project cost.
