Description
Technical field
The invention belongs to immersed tube foundation construction equipment in the waters, concrete relate to a kind of waters employed jackstone elephant trunk of immersed tube basis jackstone operation system that is used for.
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.The important step of immersed tube Foundation Design when jackstone is filled out extra large operation because the water depth and the environment in the marine site of jackstone operation have very big-difference, also can cause bigger influence to the precision of jackstone operation.Jettisoning if directly carry out building stones from rotating device, then jackstone precision poor efficiency is not high yet, and this has influenced the jackstone safety to a great extent.How can carry out the jackstone operation effectively and to improve the jackstone operating efficiency becoming present major issue to be solved.
Summary of the invention
The invention provides a kind of jackstone elephant trunk system that can satisfy the immersed tube foundation construction of efficient and location jackstone requirement; It is reasonable in design; Simple and efficient to handle; Through the accurate location that the elephant trunk of movable set setting has been realized the jackstone place and the degree of depth, can realize the simple and direct first folding and unfolding of elephant trunk simultaneously, guaranteed efficiency of construction and construction quality requirement.
The technical scheme that the present invention adopted is following:
A kind of jackstone elephant trunk system of immersed tube foundation construction is characterized in that said jackstone elephant trunk system comprises the elephant trunk that movable set is provided with, and the upper end of a said elephant trunk is provided with lifting portion, and the lower end of another elephant trunk also is provided with lifting portion; The upper and lower side of each elephant trunk is provided with limiting section.
In the specific embodiment, said elephant trunk is a tube-shaped tube, and a plurality of tube-shaped tube partner movable sets are provided with, and the outside, upper end of said the most inboard tube-shaped tube is symmetrical set otic placode, and the lower end of said the most inboard tube-shaped tube is provided with the limiting section of evagination.
In one embodiment, elephant trunk comprises an outermost tube-shaped tube, and the lower outside of outermost tube-shaped tube is symmetrical set otic placode, and the upper end of said outermost tube-shaped tube is provided with the limiting section of convex.
In one embodiment, the upper end of the adjacent tube-shaped tube of said outermost tube-shaped tube also is provided with the up limiting section of outermost tube-shaped tube.
In one embodiment, the lower end sidepiece of said outermost tube-shaped tube also is provided with hauling block, and this hauling block is symmetrically arranged two groups.
In another embodiment, the sidepiece of said elephant trunk offers through hole, and said through hole is distributed in the middle and upper part sidewall of each elephant trunk.
In one embodiment, the lateral wall of said elephant trunk is fixed with a floor, and said floor is along the outer wall setting perpendicular to elephant trunk of the bearing of trend of elephant trunk.
In the another embodiment, said elephant trunk has an outermost tube-shaped tube, and the inwall of this outermost tube-shaped tube offers the groove that the floor of the tube-shaped tube that is adjacent matches.
The elephant trunk that the jackstone elephant trunk system of this immersed tube foundation construction adopts the more piece suit to be provided with is formed; Elephant trunk is a tube-shaped tube; Limiting section through the setting of tube-shaped tube upper and lower side can suit shrinks also can extend to be opened, and the most inboard elephant trunk is positioned at topmost, this upper end of inboard elephant trunk be jackstone funnel connector; This on the upper end outer wall of inboard elephant trunk welding otic placode is set, this jackstone elephant trunk system can realize fixing or articulates through this otic placode.Otic placode is symmetrically arranged two groups, and the outside, lower end of corresponding outermost elephant trunk is also welded otic placode is set, the traction end when this otic placode is perhaps packed up as fixed end.Outer wall also is provided with the two symmetrical groups pulley in the lower end of this outermost elephant trunk, can be through drag cable by this pulley, and the downward telescopic movable of control elephant trunk is realized carrying out the control of elephant trunk length according to the jackstone condition of construction.Building stones move caused pressure variation in the jackstone process in elephant trunk in order to eliminate, and can on the sidewall of elephant trunk, offer through hole, to realize permeable or ventilative compensation.
Beneficial effect of the present invention is; The jackstone elephant trunk system of this immersed tube foundation construction can satisfy efficient and location jackstone requirement; It is reasonable in design, and is simple and efficient to handle, has realized the accurate location of the jackstone place and the degree of depth through the elephant trunk of movable set setting; The simple and direct first folding and unfolding of elephant trunk be can realize simultaneously, efficiency of construction and construction quality requirement guaranteed.
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is done further elaboration.
