Open caisson self-balancing device

Abstract

The invention relates to an open caisson self-balancing device which comprises cantilever beams, counter weights, sliding rails and gradienter, and the multiple cantilever beams and the multiple gradienter are arranged on the top of an open caisson in the circumferential direction. Each cantilever beam is connected with a balance weight through a sliding rail, the sliding rails are connected with a sliding rail driving mechanism, the sliding rail driving mechanism drives the sliding rails to drive the balance weights to move, and the sliding rail driving mechanism and the gradienter are connected with a controller. When the gradienter on the open caisson deflects, the controller receives information of the gradienter and then outputs a control signal to the sliding rail driving mechanism, the sliding rail driving mechanism drives the sliding rail to drive the counter weight to automatically move towards the cantilever beam end, and therefore self-balancing of the open caisson is achieved. The method provides convenience for balanced sinking of the open caisson, and has the advantages that the posture of the open caisson is conveniently controlled, and the surrounding environment is protected.

Description

Technical Field

[0001] The invention relates to a caisson device, in particular to a caisson self-balancing device. Background Art

[0002] Caisson is a relatively special construction technology, which can not only retain soil, but also serve as an underground structure after final sinking. However, due to various factors such as soil layer distribution, the caisson is prone to deflection during the sinking process, and even overturned in severe cases. The conventional correction mode is relatively slow and needs to be adjusted according to monitoring data. The construction is relatively cumbersome and the response is not timely. This project sets a cantilever beam, slide rail, counterweight and level at the top of the caisson. The counterweight is driven by a motor, and the level and motor are connected to the computer. When the level shows a large deflection, the computer receives the information and then controls the motor to start the counterweight to automatically move to the end of the cantilever beam through the slide rail to achieve the purpose of self-balancing, which provides convenience for the balanced sinking of the caisson and has the advantages of conveniently controlling the posture of the caisson and protecting the surrounding environment.
