Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pipe pile processing, in particular to a pipe pile cutting device for building construction. BACKGROUND

[0002] In the foundation and foundation construction of building engineering, the pile of the building is usually a concrete pipe pile. In actual construction, the concrete pipe pile is usually constructed when the foundation is excavated. For the convenience of construction, the concrete pipe pile is usually made longer than the actual length. However, after being driven to the designed depth, the excess part above the foundation bottom must be cut off, which is called pile cutting. The existing pipe pile cutting device for building construction mostly uses a common cutting machine to directly cut off the part of the pipe pile above the design elevation, which is time-consuming and labor-intensive, and cannot guarantee the flatness of the cutting plane, resulting in inaccurate data of the next step of elevation measurement, which directly affects the construction quality and construction efficiency. At the same time, it cannot cut from the inside and outside of the pipe pile, cannot classify the concrete and steel bars of the pipe pile, and cannot prevent the concrete residues cut off from falling into the pipe pile.

[0003] Chinese patent CN111794228B discloses a pipe pile cutting construction system and construction process for building construction, which realizes the simultaneous cutting of the inner and outer walls of the pipe pile through the cooperation of the outer chiseling mechanism and the inner chiseling mechanism, so that a flat gap exists on the pipe pile. Then, the cutting assembly cuts along the gap, ensuring the flatness of the cutting plane, which is beneficial to improve the cutting efficiency and the appearance of the pipe pile after cutting, and is also beneficial to the accuracy of the next step of pipe pile design elevation.

[0004] However, since the outer chiseling mechanism and the inner chiseling mechanism are respectively located inside and outside the pipe pile, when the outer chiseling mechanism and the inner chiseling mechanism work at the same time, it is impossible to ensure that they are at the same horizontal height, which may result in the failure to form a horizontal gap after working. In addition, since there is a height difference between the cutting assembly and the inner chiseling mechanism, the horizontal height of the cutting assembly needs to be adjusted after the outer chiseling mechanism and the inner chiseling mechanism cooperate to chisel out the gap. At this time, the situation inside the pipe pile cannot be observed, so it is not convenient and fast to control the cutting assembly to move to the position level with the gap, which affects the overall working efficiency.
