Active control method for slippage shipment process of large marine structure

Abstract

The invention relates to an active control method for a slippage shipment process of a large marine structure. The method can be used for solving the problem of adjusting the wharf stress in the slippage displacement process and in the shipment process at the same time. The lifting of each jack pile leg can be independently controlled through lifting adjustment of each hydraulic jack pile leg; thestress of each jack pile leg can be coordinated through carrying out lifting adjustment on all jack pile legs as needed, so that the sliding displacement process and the loading process of the structure are controlled to be smoothly carried out; and meanwhile, the phenomenon that the jack pile legs are suspended is prevented, and the problem that the structure is overturned due to the fact that certain jack pile legs damage a wharf due to too large stress is solved.

Description

technical field [0001] The invention belongs to the field of marine engineering equipment, and in particular relates to an active control method for a large-scale marine structure sliding and loading process. Background technique [0002] The slipping and loading process of large marine structures includes the slipping and shifting process and the shipping process. The slipping and shifting process is to continuously lay rectangular concrete sliders on the wharf, and lay continuous steel plates on the sliders to form a slideway. Large ocean structures There are wooden boards under the sliding shoes under the pile legs of the structures, which are in contact with the steel plates on the sliders, and lubricating oil is applied between the two for lubrication. The linear winches drag the large marine structures to slide and shift; the loading process is in A continuous slideway is laid on the barge to meet the top of the slideway on the wharf, so that it is convenient to tow la...

AI Technical Summary

Problems solved by technology

During the sliding displacement and loading process, with the movement of the structure, different positions of the wharf will have different degrees of deformation, resulting in changes in the loads, and it is necessary to adjust according to the deformation of different parts of the wharf, otherwise the wharf will be affected. Excessive force will crush the wharf and even cause large marine structures to tilt. In severe cases, it will lead to capsizing, resulting in huge safety accidents and property losses

At present, there is no method to adjust the force on the wharf during the sliding and displacement of large marine structures. For the loading process, the pressure of the structure on the wharf is adjusted by adjusting the suction and discharge of the ballast water tank of the barge, which is divided into structural Before the center of gravity of the object is on board, when the center of gravity of the structure is on board, and after the center of gravity of the structure is on board, this method is an indirect method of adjusting the force on the wharf. The adjustment process is cumbersome and not timely. And the adjustment effect is not ideal
