Flexible device of underground continuous wall for preventing concrete circuitous flowing

Abstract

The invention relates to a flexible device of continuous concrete wall for preventing concrete flow around, which is characterized in that the flexible device comprises a capsule and filling in the capsule, wherein the capsule is located between the connector of the first-period groove and the second-period groove and the earth of the second-period groove, and the periphery of the capsule can contact with the inner walls of the connector of the first-period groove and the second-period groove after the capsule is filled with filling. The flexible device has the characteristics of excellent compactness, convenient construction and high efficiency, solves the problem that a rigid device can not be pulled out expressing in the background technology, and can effectively prevent the concrete flow around to the second-period groove section to affect the construction of the second-period groove section when used on the first-period groove section construction of the continuous concrete wall.

Description

technical field [0001] The invention relates to an underground diaphragm wall in the fields of civil engineering, construction, municipal engineering, water conservancy and the like, and in particular to a flexible device for preventing concrete from bypassing the underground diaphragm wall. Background technique [0002] When the existing underground diaphragm wall is constructed in the first-stage trough section, the phenomenon of concrete flowing around the second-stage trough section often occurs. The conventional treatment method is to use elastic steel sheets, colored strips or foam at the joints of the first-stage trough section And other ways to prevent concrete circumvention, but the effect is not ideal. The main problems are as follows: first, the concrete in the first-stage trough will flow around to the second-stage trough, wasting a lot of concrete; second, the steel bars in the second-stage trough cannot be installed in place; third, the construction of the seco...

Problems solved by technology

[0002] When the existing underground diaphragm wall is constructed in the first-stage trough section, the phenomenon of concrete flowing around the second-stage trough section often occurs. The conventional treatment method is to use elastic steel sheets, colored strips or foam at the joints of the first-stage trough section and other methods to prevent concrete flow around, but the effect is not ideal

The main problems are as follows: first, the concrete in the first-stage trough will flow around to the second-stage trough, wasting a lot of concrete; second, the steel bars in the second-stage trough cannot be installed in place; third, the construction of the second-stage trough For a period of time, it is necessary to use methods such as impact to clean up the bypassed concrete, which is time-consuming and laborious; fourth, the use of foam as an anti-concrete bypass construction is not only costly, cannot be reused, and is inconvenient to construct

The anti-concrete bypass device described in this patent is a rigid component, which has the advantages of reusability, low cost, convenient construction, high efficiency, less concrete flowing into the second-stage tank, and convenient handling during the construction of the second-stage tank, but there are The disadvantage is that once the rigid component device cannot be pulled out, the second-stage groove will be difficult to construct, which will have a great impact on the subsequent construction of the diaphragm wall
