Embodiment Construction

[0016] Such as figure 1 and figure 2 As shown, the riprap chute retracting system for the immersed tube foundation construction can be set on the immersed tube foundation construction barge 20, which mainly consists of a riprap chute 10 and a retractable traction cable 17. The riprap chute 10 is a multi-section cylindrical tube set in a movable suit, the upper end of the innermost cylindrical tube is connected to the lower port of the riprap funnel 14, and the upper part of the innermost cylindrical tube is pivotally connected to the chute trolley. . The upper part of the innermost cylindrical tube of the riprap chute is pivotally connected to the chute trolley through the ear plate 12; Set retractable traction rope 17 traction settings. The riprap chute is arranged on a chute trolley 13, which is assembled with a track, and a pulley 15 is arranged at intervals on one side of the chute trolley, and the other end of the retractable traction cable 15 passes through the pulle...

Abstract

A rip-rap lephant trunk retraction system for immersed tube foundation construction is characterized in that the retraction system comprises a rip-rap lephant trunk and a retraction pulling cable, wherein the upper end of the rip-rap lephant trunk is arranged in a pivotally connected manner, the lower end of the rip-rap lephant trunk and the retraction pulling cable are arranged in a traction manner, and the lower end of the rip-rap lephant trunk is arranged in a rotating manner around the pivoted part between the vertical direction and the horizontal direction of the lephant trunk. The rip-rap lephant trunk retraction system for immersed tube foundation construction is simple and fast to operate, can effectively achieve lephant trunk retraction, is reasonable in design, occupies a small area, meanwhile can achieve the retraction operation of the lephant trunk on water in virtue of the driving force of a lephant trunk trolley, and can be operated repeatedly. The manufacturing manner of the retraction system is simple, the normal use of the rip-rap lephant trunk cannot be impacted, and also the security under a non-riprap state can be ensured.

Description

technical field [0001] The invention belongs to a riprap device for immersed tube foundation construction in water areas, and in particular relates to a riprap chute retractable system for immersed tube foundation construction that can retract and retract the riprap device. 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 cumbersome. Ship traffic and posit...
