Description

Technical Field

[0001] The utility model relates to the technical field of cast-in-place pile construction, and more specifically to a device for integrally breaking the pile head of a cast-in-place pile. Background Art

[0002] Bored cast-in-place piles are widely used in bridge engineering because of their reliable quality, simple construction technology and strong adaptability to the strata.

[0003] At present, during the construction of bored piles, it is necessary to use a breaking device to break the bored pile head. However, the breaking device needs to be broken step by step by cutting and drilling during the breaking process, which is time-consuming and reduces work efficiency. In addition, it is also time-consuming and labor-intensive to position the breaking device between the bored pile head, which brings inconvenience to use.

[0004] For example, publication number CN117266154A discloses a bored pile head breaking device and construction method, which includes a mounting frame, which is sleeved on the bored pile head, and a sliding guide unit is provided on the mounting frame, and a cutting machine is provided on the sliding guide unit. The sliding guide unit can drive the cutting machine to rotate one circle along the circumference of the bored pile head.

[0005] It can be seen from the above-mentioned public scheme that when breaking the pile head of the bored pile, it is necessary to rotate the pile head along the circumference of the pile for one circle and then drill a hole. The whole process takes a long time to complete, and the positioning between the mounting frame and the pile head of the bored pile is also cumbersome and time-consuming. Utility Model Content
