Deviation rectifying device suitable for sinking process of steel cofferdam

Abstract

The invention provides a deviation rectifying device suitable for the sinking process of a steel cofferdam. The deviation rectifying device comprises a fixing frame, rails and a transferring mechanism. The rail is fixedly arranged below the fixing frame in the circumferential direction of a fixing base. The transferring mechanism is connected with the side walls of the rails in a rolling mode. Thetransferring mechanism comprises two roller sets, a telescopic shell and a telescopic air cushion. The roller sets are connected with the side walls of the rails in a rolling mode, the telescopic shell is connected with the roller sets, the telescopic shell can move along the rails, meanwhile, the telescopic shell drives the roller sets to abut against the fixing frame under the buoyancy acting force, and the fixing frame bears upward buoyancy. Based on the sinking direction of the steel cofferdam, the telescopic shell moves to the lowest position of the steel cofferdam along the rails, the telescopic shell stretches out and draws back along with stretching out and drawing back of the telescopic air cushion, and therefore the buoyancy of the telescopic shell can be adjusted in time, the steel cofferdam bears upward buoyancy opposite to the sinking direction in the sinking process, balance of the steel cofferdam is guaranteed, the construction cost of deviation rectification of the steel cofferdam is greatly reduced, and the working efficiency is high.

Description

technical field [0001] The invention relates to the field of steel cofferdam engineering machinery, in particular to a deviation correcting device suitable for the sinking process of steel cofferdams. Background technique [0002] As a water retaining structure for bridge cap construction, steel cofferdams are widely used in deep water foundation construction and foundation pit support engineering. The steel cofferdam needs to be lowered to the soil through the positioning guide device after the assembly is completed. [0003] In related technologies, steel cofferdams tend to incline during positioning and sinking. Faced with the inclination of the steel cofferdam, it can be adjusted through external pulling and jacking, mainly controlled by external equipment, which requires high equipment, and the overall deviation correction project costs are high and work efficiency is low. Contents of the invention [0004] In order to solve the above technical problems, the present...
