Reinforcement equipment and reinforcement construction technology for bridge piers

Abstract

The invention relates to a bridge pier rebar-embedding reinforcement device and a reinforcement construction technique thereof. The bridge pier rebar-embedding reinforcement device comprises an executive mounting frame, wherein an executive telescopic cylinder is mounted on the side wall of the executive mounting frame; the top end of the executive telescopic cylinder is mounted on an executive mounting plate by a flange; executive telescopic rods are arranged between the executive mounting frame and the executive mounting plate; executive telescopic springs are sleeved on the executive telescopic rods; an executive driving mechanism is mounted at the middle of the side wall of the executive mounting plate; two executive auxiliary mechanisms are mounted on the side wall of the executive mounting plate; and a drill rod body is clamped on the executive driving mechanism. The bridge pier rebar-embedding reinforcement device can solve the difficult problems in an existing pier rebar-embedding reinforcement process that the drilling operation needs to be performed manually with the aid of existing drilling tools, that the verticality between a drilling hole and a working surface needs to be manually controlled, that a drill rod can not be manually guaranteed to be always perpendicular to the working surface, that the drill rod is prone to vibration, malposition and the like when thedistance of the drilling hole is too long, and that the drill rod is prone to be broken to cause hidden dangers.

Description

technical field [0001] The invention relates to the field of construction and bridge equipment, in particular to reinforcement equipment for planting bars on bridge piers and a reinforcement construction process thereof. Background technique [0002] The pier is an important part of the bridge. The pier is located in the middle of the bridge and supports the upper structure of the two adjacent spans. Its function is to transfer the load from the superstructure to the foundation reliably and effectively. The service life of the pier will be seriously affected under the pressure of external forces and natural disasters if the pier is used for too long. Certain measures need to be taken to strengthen the pier. Building reinforcement mainly uses carbon fiber, bonded steel, planting bars, and high-pressure grouting to strengthen the building. Planting bars requires drilling on the surface of the pier. During the drilling process, the drill bit and the column surface must always b...

Problems solved by technology

[0003] In order to solve the above-mentioned problems, the present invention provides a kind of bridge pier reinforcement equipment and its reinforcement construction technology, which can solve the need to manually carry out drilling operations with the help of existing drilling tools in the existing bridge pier reinforcement process. The verticality between the drilling hole and the working face is manually controlled, and the stability of the drilling operation is poor with the help of existing drilling tools, and it is impossible to ensure that the drill pipe and the working face are always vertical, and when the drilling distance is too long, the drill pipe It is prone to vibration and dislocation, and it is easy to cause the drill pipe to break, which poses a safety hazard. When drilling holes with different specifications, it is necessary to replace the drill pipe. The operation is complicated, the effect of sound strength reinforcement, manual drilling is labor-intensive, and work efficiency is low. It can realize the function of automatic and precise drilling of reinforced bridge piers without manual operation, no potential safety hazards, and has the advantages of good stability, low labor intensity and high work efficiency.
