Round open caisson mechanical correction equipment for bridge pier and abutment construction

Abstract

The invention relates to a circular caisson mechanized correction equipment for bridge pier construction, comprising a hoisting plate, a hoisting frame is installed on the hoisting plate, a hoisting drive motor is installed on the hoisting plate through a motor base, and an output shaft of the hoisting drive motor A hoisting driving plate is installed on the top, and the lower end of the hoisting driving plate is provided with a hoisting adjustment device along its circumferential direction. The present invention can solve the problems in the existing caisson construction and correction process that manual construction of caisson scaffolding is required, manual monitoring of caisson inclination is required, manual construction of caisson scaffolding is complex, time-consuming, and requires a large amount of work, and manual construction of scaffolding is impossible. Mobile, poor flexibility, needs to build suitable scaffolding for caissons of different specifications, high labor intensity, low work efficiency and other problems; it can realize the function of mechanized correction construction of circular caissons.

Description

technical field [0001] The invention relates to the technical field of bridge pier caisson construction equipment, in particular to a circular caisson mechanized correction equipment used for bridge pier abutment construction. Background technique [0002] The caisson is a well-shaped structure. It excavates the soil in the well, relies on its own gravity to overcome the friction of the well wall, and then sinks to the design elevation. Then it is sealed with concrete and the well hole is filled to make it the foundation of the bridge pier. It is the most important process in the construction of bridge piers. The caisson process is as follows: a building or building foundation located at a certain depth underground is first made into a caisson on the surface, and then the caisson is gradually excavated from the well under the protection of the well wall, so that the caisson gradually falls under the action of its own weight. After sinking and reaching the predetermined desi...

Problems solved by technology

[0003] In order to solve the above problems, the present invention provides a circular caisson mechanized correction equipment for bridge pier construction, which can solve the existing caisson construction and correction operations that require manual construction of caisson scaffolding and manual monitoring of caissons. The degree of inclination of the well, the manual construction of caisson scaffolding is complicated, time-consuming, and the amount of work is large. The manual construction of scaffolding cannot be moved and has poor flexibility. It is necessary to build suitable scaffolds for different specifications of caissons, which is labor-intensive and low-efficiency. ; It can realize the function of mechanized correction construction of circular caissons, can monitor the inclination of caissons in real time, and can adjust according to the specifications of caissons, and has the advantages of simple operation, good flexibility, short time-consuming, small engineering quantity and work High efficiency and other advantages
