Mounting and constructing method for deepwater comb-shaped slide cross beam

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 of slipway, in particular to a deep-water comb-shaped slipway well-shaped beam installation and construction method based on short-segment matching prefabrication, rolling pre-assembly and underwater high-precision installation. Background technique [0002] With the continued prosperity of the water transportation market and the increase in the size of ship structures, the number of track groups of the transverse comb slides has increased, and the depth of the slides’ water penetration has also increased. This raises the issue of the installation accuracy of the rails on the chute beams of the slides. higher requirement. [0003] In the prior art, the traditional construction technology for the underwater installation of the cross-comb berth slideway is to use a hoisting boat to lift the hoisting beam from the transport barge and then move the hoisting boat to a set position to slide the ho...

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
