Foundation construction barge for immersed tube

Abstract

The invention discloses a foundation construction barge for an immersed tube, which is characterized in that a rail extending in the barge direction is arranged on one side of the barge main deck; a travelling mechanism is arranged on the rail and driven by a cable winch; the travelling mechanism comprises an elephant trunk trolley and a flat rammer trolley; the elephant trunk trolley is connected with an elephant trunk system located on one side of the barge; and the flat rammer trolley is loaded with a vibratory hammer and a vibratory hammer lifting system. The foundation construction barge for the immersed tube is reasonably designed in structure, has multiple functions, and meets the engineering requirements of stone transportation, accurate riprap and hammering. The barge is highly effectively to operate, flexible and can realize the area construction requirement of a fixed point. The barge can be formed by modifying the prior ship; each device on the barge is reasonably distributed; and the barge can meet the requirements of island tunnel construction, construction safety and reliability.

Description

technical field [0001] The invention belongs to the immersed tube construction technology in the construction process of bridge and tunnel engineering, and in particular relates to an immersed tube foundation construction barge used for immersed tube construction in offshore island and tunnel engineering. Background technique [0002] With the upsurge of coastal development at home and abroad, the construction of corresponding coastal projects has increased. When the cofferdam island tunnel construction is carried out in the sea area, it is necessary to carry out the cofferdam island construction. Ramping is carried out to form a solid island wall cofferdam structure. Due to offshore construction, the corresponding immersed pipe operation, riprap sea reclamation and tamping process all require a variety of equipment to cooperate. If multiple ships are used for operations with different functions, the work site will be difficult to meet the needs and the operation will be cum...

AI Technical Summary

Problems solved by technology

Due to offshore construction, the corresponding immersed pipe operation, riprap sea reclamation and tamping process all require a variety of equipment to cooperate. If multiple ships are used for operations with different functions, the work site will be difficult to meet the needs and the operation will be cumbersome. Ship traffic and positioning security issues

In addition, the riprap reclamation operation requires a large amount of stonework, not only to meet the loading requirements, but also to perform the riprap operation at a precise location and the subsequent underwater compaction. The existing equipment cannot meet the requirements of high efficiency and construction period
