Problems solved by technology

The existing outer ring pipe pile cutting process is limited by the uneven excavation depth of the earthwork and the height of the pipe piles. The cutting of the pipe piles needs to be repeated many times, which is time-consuming and laborious. The risk of pipe pile damage seriously affects the quality of the pile body, which in turn affects the overall quality of the project

Abstract

The invention relates to PHC tubular-pile internal-expansion-type cutting equipment and a using method thereof. The PHC tubular-pile internal-expansion-type cutting equipment comprises a rotation driving mechanism, a double-sleeve-tube tool post and a tool bit. One end of the double-sleeve-tube tool post is connected with the rotation driving mechanism, the other end of the double-sleeve-tube tool post is connected with the tool bit, the double-sleeve-tube tool post comprises an inner tool post rod and an outer tool post tube which sleeves the inner tool post rod, and the length of the inner tool post rod is adjustable. According to the PHC tubular-pile internal-expansion-type cutting equipment, cutting of tubular piles before an earthwork is excavated can be achieved, so that the influence of the lateral pressure of earthwork excavation on the tubular piles is avoided fundamentally, perturbation of earthwork excavation on the tubular piles is avoided, and the engineering quality is ensured; and the tool bit integrates the four functions of hole drilling in a soil layer, inner hole deslagging, cutting-off at a fixed point and tool retracting through inward contraction, using is convenient, and the practicability is high.

Description

technical field [0001] The invention relates to a PHC pipe pile internal expansion cutting device and a using method thereof, belonging to the field of construction machinery. Background technique [0002] With the development of the construction industry at home and abroad, high-rise super-high-rise has become the mainstream. PHC pipe pile foundation is widely used in the foundation construction of high-rise buildings because of its high bearing capacity and many advantages such as uniform settlement. Pile foundation construction is an important link in building construction, and its construction quality has decisive significance for the overall performance of buildings. At present, the main quality problems in the construction technology of PHC pipe piles are pile position offset, inclination, and fracture. The existing outer ring pipe pile cutting process is limited by the uneven excavation depth of the earthwork and the height of the pipe piles. The cutting of the pipe ...
