A construction method for the installation and construction of well-shaped beams in comb-shaped slideway in deep water

Abstract

The invention discloses a mounting and constructing method for a deepwater comb-shaped slide cross beam, which is based on and integrates short section matched prefabrication, rolling pre-assembly and underwater mounting and construction, and solves the difficult problems in the traditional construction method that the construction risk is higher as long-time diving operation of divers is required, besides, the elevation and axis alignment are difficult to control and the requirement for high-precision mounting of rails on the slide cross beam cannot be met as the slide cross beam is simultaneously influenced by storms and water flows. According to the method, the prefabricating line type, the pre-assembly line type and the mounting line type of the slide cross beam are dynamically adjusted and controlled in a real-time manner, no error accumulation is generated during the whole beam construction, so that the beam is precise in size and line type; the method has the advantages of high technological content, high degree of factory-like and mechanized operation, environmental protection and the like, and facilitates the organic integration of the advanced computer technology and electrical and mechanical manufacturing technology with the slipway slide construction technology.

Description

technical field [0001] The invention relates to the technical field of slipway construction technology, in particular to a construction method for deepwater comb-shaped slide way well-shaped beams based on short-segment matching prefabrication, rolling pre-assembly and underwater high-precision installation. Background technique [0002] With the continuous prosperity of the water transportation market and the increase of the ship structure scale, the number of rail groups of the horizontal comb slideway increases accordingly, and the water entry depth of the slideway also deepens. higher requirement. [0003] In the prior art, the traditional construction technology of the underwater installation of the well-shaped girder of the transverse comb-type slipway slideway is to use the crane barge to hoist the well-shaped beam away from the transport barge and then move the crane barge to the set position, so that the sliding well-shaped beam After sinking into the water, the di...

AI Technical Summary

Problems solved by technology

The traditional construction method requires divers to dive for a long time, and the crane can only leave after the well-shaped beam is installed in place. The construction risk is high and the energy consumption is high; the slideway well-shaped beam is affected by wind waves and currents at the same time, and the elevation and axis alignment It is difficult to control and cannot meet the high-precision installation requirements of the track on the well-shaped beam of the slideway
