Problems solved by technology

[0009] 1. When the excavator digs the soil to expose a section of the pile, because there are piles, the efficiency of digging is low
[0010] 2. Manual cutting with cutting machine, low efficiency
[0011] 3. The section of the pile that has been cut needs to be dug out by an excavator. Because it is not a professional bucket but a commonly used soil bucket, the digging efficiency is low

Abstract

The invention belongs to the technical field of pile cutting, and particularly relates to a pile cutting device in the green building pile foundation construction process. The pile cutting device comprises a fixed connecting cylinder, a hydraulic motor, a driving cylinder, a mounting cylinder, a reset plate spring, a reset spring, a cutting fan-shaped plate, an adjusting mechanism and a tightening plate spring. According to the pile cutting device, after the end face of the side, away from the cutting fan-shaped plate, of a limiting shell makes contact with the limiting face of a corresponding limiting clamping block, if a cut pile body cannot fall off through gravity, the cutting fan-shaped plate further clamps the cut pile body, at the moment, only the driving cylinder needs to be continuously rotated, a limiting rod on the driving cylinder continuously drives the limiting clamping block mounted on the limiting rod to move, a second inclined face on the limiting clamping block extrudes the limiting shell, the limiting shell continuously drives the cutting fan-shaped plate to move till the cutting fan-shaped plate completely enters a third mounting shell at the lower end of the mounting cylinder, and after the pile body falls off, the cutting fan-shaped plate enables the limiting clamping block to limit the cutting fan-shaped plate through the limiting face under the action of the tightening plate spring.

Description

[0001] Technical field [0002] The invention belongs to the technical field of pile cutting, and in particular relates to pile cutting equipment in the construction process of green building pile foundations. Background technique [0003] For high-rise buildings, the foundation is often reinforced with poured cement piles. After the pouring is completed, the upper end of the pile is cut off so that the upper ends of all the piles are coplanar and horizontal; the specific operation process is as follows: [0004] 1. Use a small excavator to dig out a section of each pile. [0005] 2. Manually use a cutting machine to cut off a section of the exposed pile to ensure the coplanar level. [0006] 3. Use an excavator to dig out the cut piles. [0007] Afterwards, pressure is applied and then reinforced concrete is added to form the foundation. [0008] As mentioned above, there are the following problems in the pile cutting process: [0009] 1. During the excavation process of ...
