Embodiment Construction

[0025] Those skilled in the art should understand that the embodiments in this section are only used to explain the technical principle of the present invention, and are not used to limit the protection scope of the present invention. For example, although the present embodiment describes the demolition method of the present invention in conjunction with pile heads, the demolition method of the present invention can also be used in other occasions, the demolition of cylindrical objects of rock-based hard and brittle materials. Technicians can make adjustments as needed to suit specific applications. Obviously, the adjusted technical solution will still fall into the protection scope of the present invention.

[0026] It should be noted that, in the description of the present invention, the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" etc. Terms indicating directions or positional relationships are based on the directions or pos...

Abstract

The invention belongs to the technical field of detachment of brittle solid, and particularly provides a pile head breaking method in order to solve the problems that pile head detachment efficiency is low, the cost is high, and pollution is serious. The pile head breaking method comprises the steps that a plurality of operation holes are formed in a to-be-broken axis surface of a pile head; an intra-hole cylinder type hydraulic stone breaker is provided and comprises a set of expansion devices matched with the operation holes; and the set of expansion devices are inserted into the multiple corresponding operation holes so that the intra-hole cylinder type hydraulic stone breaker can act, and the pile head is expanded and broken along the to-be-broken axis surface. By means of the pile head breaking method, the breaking efficiency of the pile head is improved, the breaking cost is saved, and breaking pollution is reduced.

Description

technical field [0001] The invention belongs to the technical field of demolition of brittle solids, and specifically provides a method for demolition of a pile head. Background technique [0002] The pile heads are made of concrete with an internal steel cage. At present, in the demolition construction of the pile head, the manual method or the pile breaker construction method is usually used. The artificial method is to first chisel off the protective layer concrete outside the pile head reinforcement with a pick to expose the reinforcement, and then wedge the steel drill along the concrete circumference inside the reinforcement cage at the same horizontal plane, taking advantage of the fact that the compressive strength of the concrete is much greater than the tensile strength With the help of the tension of the steel drill wedge, a section of the pile head on the upper part of the pile head is separated from the expansion crack of the lower part, and then cleared out wi...
