Equipment and method for removing pile head of bridge pile foundation

Abstract

The invention relates to a bridge pile foundation pile head cutting device and method. The bridge pile foundation pile head cutting device comprises a cutting base plate, a supporting air cylinder ismounted at the lower end of the cutting base plate, a supporting circular plate is mounted at the top end of the supporting air cylinder through a flange, embracing devices are symmetrically arrangedon the left side and the right side of the lower end of the cutting base plate, and the lower ends of the embracing devices are connected to a cutting device body. The following difficult problems, existing in the cutting process of an existing pile foundation pile head, that a, as for the existing pile foundation pile head, the pile head of a pile foundation needs to be cut manually by using a cutting machine, the positions of concrete and steel bars cannot be judged accurately in cutting operation, and consequently a disk saw on the cutting machine is prone to being broken off, and b, the labor intensity of breaking and clearing concrete on the pile foundation pile head by manually hand-holding a drilling rig is large, potential safety hazards exist, tools need to be used for fixing during breaking and cutting of the pile foundation pile head, by manually hand-holding the drilling rig, only one point can be broken, the consumed time is long, and the working efficiency is low can be solved.

Description

technical field

[0001] The invention relates to the technical field of construction equipment, in particular to equipment and a method for removing pile heads of bridge pile foundations. Background technique

[0002] In the process of bridge construction, the pile foundation needs to be built first. In order to ensure the quality of the pile head during the pile foundation construction, the elevation of the pile top is generally higher than the design elevation. The pile head in the pile foundation construction is made of reinforced concrete. Excess pile foundation pile heads need to be cut off after completion.

[0003] However, the following difficult problems exist in the cutting process of existing pile foundation pile heads, a. Existing pile foundation pile heads need to be cut off manually using a cutting machine, and the positions of concrete and steel bars cannot be accurately judged during the cutting operation. It is easy to cause the circular saw on the cutting m...
