Description

Technical Field

[0001] The utility model relates to the technical field of pile foundation construction, in particular to a pile body cutting construction device. Background Art

[0002] In order to solve the problem of pile cutting after the construction of cast-in-place piles is completed, the following equipment is currently available on the market:

[0003] 1. Hydraulic ring pile cutter

[0004] For example, the existing patents CN103374914A "A Fully Automatic Hydraulic Pile Cutting Machine" and CN209779624U "Combined Hydraulic Pile Cutting Machine" have high construction efficiency, but their working principle is to use a hydraulic system to squeeze the cutter, which can be regarded as a pile tip breaking technology. The cross section after the pile is cut is rough, and the pile head broken by squeezing has a certain impact on the quality of the pile body. In addition, the hydraulic system is expensive. If one of the hydraulic systems fails, it can no longer be used and needs to be repaired.

[0005] 2. Hand-push pile cutter

[0006] The hand-push pile cutter is a machine that fixes the motor and cutter on a two-wheel or four-wheel trolley, and uses a belt drive to apply the kinetic energy generated by the motor to the cutter. Although it is easy to construct and has low cost, its disadvantage is that the level of the cutter depends entirely on the support wheel. During the cutting process, as the wheel moves, the cutter can move up and down during the cutting process. For a high-speed rotating cutter, there is a risk of the cutter getting stuck or even breaking. The risk factor is high. Even if the cut is completed, the cut may not be level. This will affect the vertical bearing test of the pile foundation.

[0007] 3. Hoop-type pile cutter

[0008] The clamp-type pile cutter uses its own clamp to connect the pile cutting equipment to the pile, and uses the motor to drive the tool to cut. The cross section cut by this cutting method can ensure the cross section is flat, but this type of pile cutter is subject to the limitation of the clamp. It can only act on piles with relatively regular pile bodies, such as prefabricated pipe piles. Piles with regular pile bodies can ensure the normal installation of the clamp. However, for irregular pile bodies such as cast-in-place piles, the use of this type of pile cutter is limited.

[0009] Therefore, the current hydraulic annular pile cutter, hand-push pile cutter, and hoop-type pile cutter all have certain disadvantages and are not suitable for use with irregular pile bodies such as cast-in-place piles. Utility Model Content
