An anti-collapse hole device and method for synchronous waterproofing

Abstract

The present application relates to a synchronous waterproof anti-slump hole device and method, which includes a casing body, the casing body includes several casing panels spliced ​​with each other, and the casing body is connected with a device for expanding and contracting the casing body The expansion assembly is detachably connected to the casing main body, and a locking assembly is arranged between adjacent casing plates. The application has the effect of making the outer wall of the casing main body collide with the inner wall of the pile hole by controlling the anti-collapse hole device, thereby reducing the probability of pile hole collapse and reducing construction costs.

Description

technical field [0001] The present application relates to the field of building construction, in particular to a synchronous waterproof anti-collapse hole device and method. Background technique [0002] Cast-in-situ cast-in-situ piles have a high bearing capacity. During construction, bored cast-in-place piles are often used as the foundation. Since bored cast-in-place piles are mostly below the groundwater level, they are difficult to survey and control during construction. When there is groundwater flow Or when quicksand passes through, the phenomenon of hole collapse often occurs, which directly affects the construction progress and construction safety of the whole project. [0003] To solve such problems, the traditional hole-forming process is usually used to add a steel casing to protect the wall, and the steel casing is hammered into the soil by a pile driver to reduce the phenomenon of hole collapse. [0004] In view of the related technologies mentioned above, the...

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that when the pile hole is deep, the steel casing is difficult to press in and the construction cost is relatively high.
