Pile head breaking device and pile breaking construction method

Abstract

The invention relates to a pile head breaking device and a pile breaking construction method, and belongs to the technical field of pile breaking. The pile head breaking device comprises an upper clamping ring, a breaking positioning ring, a lower clamping ring and a clamping plate. The upper clamping ring, the breaking positioning ring and the lower clamping ring are arranged from top to bottom and connected through two symmetrical connecting plates, the connecting plates are straight plates, opposite bayonets are formed in the connecting plates, the upper clamping ring and the lower clamping ring respectively, the opposite bayonets form clamping grooves, and the clamping grooves are connected with the breaking positioning ring. A clamping groove formed between the upper clamping ring and the connecting plate and a clamping groove formed between the lower clamping ring and the connecting plate are vertically through, and the clamping plate is arranged in the vertically-through clamping groove and can vertically slide in the clamping groove. When the pile head breaking device is used for breaking a pile head, the position of the clamping plate needs to be adjusted, the breaking efficiency of the pile head can be greatly improved, the influence on a lower pile body structure in the breaking process can be reduced to the maximum extent, the broken section is smooth, and the workload of subsequent manual correction is reduced.

Description

technical field [0001] The invention belongs to the technical field of pile breaking, and in particular relates to a pile breaking device and a pile breaking construction method. Background technique [0002] Bored piles are widely used in highway bridges and other engineering fields due to their strong adaptability, high bearing capacity and easy construction. Cast-in-situ piles are concealed projects, but since there are many factors that affect the construction quality of cast-in-place piles, strict requirements must be imposed on every link of the construction process. Usually, the "pile foundation is poured with underwater concrete and the super-filled concrete on the top of the pile is chiseled out" The work is called "breaking the pile head" or "cutting the pile head". "Breaking the pile head" is the last key process in the construction of bored piles, and it is also an indispensable part of the construction of bored piles. When breaking the pile head, it is necessa...

Problems solved by technology

[0003] At present, the mechanical method of removing piles is mainly used, that is, manual use of pneumatic picks to gradually remove them carefully. This method of removal is not only laborious, but also the surface of the pile after removal is not smooth, requiring further fine operations in the subsequent sequence, which consumes a lot of manpower and is low in efficiency.
