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 positio

Embodiment Construction

[0019] Such as figure 1 and figure 2 As shown, the immersed tube foundation construction barge is a non-self-propelled barge 10, and one side of the main deck 11 of the barge is provided with a track 14 extending along the direction of the hull. A traveling mechanism is arranged on it, and the traveling mechanism includes a pipe slide car 20 and a ramming car 30, and the number of the pipe chute car and the ramming car can be set according to the size of the hull and actual construction needs. The bottoms of the pipe slide car and the tamping car are provided with a sliding body matched with the pre-track, the sliding body is embedded in the inside of the two rails, and slide plates are provided on the contact surfaces of the sliding body and the rail. The pipe slide car and the leveling car are driven and set by the cable winch 40, the pipe slide car 20 is connected to the pipe slide system on one side of the barge, and the leveling car is equipped with a vibratory hammer a...

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...
