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
The invention belongs to the jackstone device of immersed tube foundation construction in the waters, concrete relate to a kind of jackstone elephant trunk extension and retraction system that can carry out the immersed tube foundation construction of folding and unfolding the jackstone device.
Background technology
Along with domestic and international coastal development upsurge, corresponding coastal engineering construction increases, and need carry out the construction of island, cofferdam when carrying out the tunnel construction of island, cofferdam in the marine site; Adopt steel pipe pile to make up island, cofferdam wall; Carry out the jackstone operation of rockfilling then, ram flatly again, form firm island wall cofferdam structure.Because construction at sea; Corresponding immersed tube operation, jackstone are filled out the sea and rammed flat operation all needs plurality of devices to cooperate; If adopt a plurality of ships to carry out the operation of difference in functionality, then the operation place is difficult to satisfy the demand and also has simultaneously complex operation, shipping traffic and positioning security problem.In addition, jackstone is filled out extra large operation needs a large amount of cubic meters of stone, not only will satisfy delivery and require also will accomplish that the jackstone operation in accurate place, existing equipment can't satisfy efficient and construction period.This case inventor has invented the technology that the elephant trunk that adopts tubulose carries out jackstone, and it adopts the metal tub pipe that satisfies the jackstone diameter guiding device as the fixed point jackstone, and the metal tub pipe extends to underwater dumped rockfill basis district, carries out the jackstone operation then.Because the length of this metal tub pipe is bigger, when barge carries out non-jackstone operation its deeply under water part can have potential safety hazard.
Summary of the invention
The invention provides a kind of jackstone elephant trunk extension and retraction system of simple and efficient to handle, the immersed tube foundation construction that can effectively realize the elephant trunk folding and unfolding; It is reasonable in design; It is little to take up room, and can realize the folding and unfolding operation of elephant trunk on the water surface simultaneously by the driving force that Liu manages dolly, but and repeatable operation.The production method of this extension and retraction system is simple, does not influence the normal use of jackstone elephant trunk, can guarantee the safety under the non-jackstone state again.
The technical scheme that the present invention adopted is following:
A kind of jackstone elephant trunk extension and retraction system of immersed tube foundation construction; It is characterized in that said extension and retraction system comprises jackstone elephant trunk and folding and unfolding drag cable; The upper end of said jackstone elephant trunk articulates and is provided with; Its lower end and the traction of said folding and unfolding drag cable are provided with, and this jackstone elephant trunk its lower end under the traction of said folding and unfolding drag cable articulates the position rotary setting in the vertical direction and the horizontal direction spaced winding of elephant trunk.
In the specific embodiment, the upper end of said jackstone elephant trunk is provided with otic placode, and said jackstone elephant trunk articulates through otic placode and is provided with; The lower end of said jackstone elephant trunk also is provided with otic placode, and said otic placode is provided with by the folding and unfolding drag cable traction of oblique setting.
In one embodiment, said jackstone elephant trunk is the more piece tube-shaped tube that movable set is provided with, and settings dock in the upper end of inboard tube-shaped tube with the lower port of jackstone funnel, and this is the top and the elephant trunk dolly pivot joint setting of the tube-shaped tube of inboard.
In another embodiment, the lower end of said outermost tube-shaped tube is provided with otic placode, and said otic placode is provided with by the traction of folding and unfolding drag cable.
In one embodiment, said jackstone elephant trunk is arranged on the elephant trunk dolly, and the assembling of this elephant trunk dolly and a track is provided with, and is arranged at intervals with a pulley in a side of elephant trunk dolly, and the other end of said folding and unfolding drag cable is provided with by haulage gear traction behind this pulley.
In the embodiment, the distance of said elephant trunk dolly and pulley spare is more than or equal to the length of said elephant trunk again.
The lower end that the jackstone elephant trunk extension and retraction system of this immersed tube foundation construction is utilized in the jackstone elephant trunk is provided with the folding and unfolding drag cable.Affect the lower end of jackstone elephant trunk to realize rotation through this folding and unfolding drag cable, thereby realize the folding and unfolding operation of jackstone elephant trunk around the articulated section of jackstone elephant trunk upper end.The jackstone elephant trunk can realize around the pivot joint position of its upper end level to traction, when non-jackstone operation, stretch into existing potential safety hazard and course obstruction under water thereby eliminate the jackstone elephant trunk.The tube-shaped tube that the jackstone elephant trunk can adopt the more piece suit to be provided with can extend to darker foundation bottom under water when carrying out jackstone.When carrying out the folding and unfolding operation; Can be earlier the tube-shaped tube of suit be shunk; Then with the lower end of jackstone elephant trunk through the folding and unfolding drag cable to the skew back tractive that makes progress; The jackstone elephant trunk is under the draw of this folding and unfolding drag cable, and whole elephant trunk is rotated around the articulated section of its upper end, draws to the appropriate location until the folding and unfolding drag cable.The oblique traction of folding and unfolding drag cable can be passed through the pulley setting, and pulley plays the effect that changes folding and unfolding drag cable direction, makes the pulling equipment that is positioned at jackstone elephant trunk dolly opposite side to connect driving to this folding and unfolding drag cable.
Beneficial effect of the present invention is; The jackstone elephant trunk extension and retraction system of this immersed tube foundation construction is simple and efficient to handle, can effectively realize the elephant trunk folding and unfolding, and it is reasonable in design, and it is little to take up room; Can realize the folding and unfolding operation of elephant trunk on the water surface simultaneously by the driving force that Liu manages dolly, but and repeatable operation.The production method of this extension and retraction system is simple, does not influence the normal use of jackstone elephant trunk, can guarantee the safety under the non-jackstone state again.
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is done further elaboration.
