Description
Technical field
The present invention relates to marine jacket installation technical field, especially a kind of first stake formula packer.
Background technology
" first drive piles " construction method, is mainly used in offshore wind farm field at present, at sea in platform using less, in wind
Electrical domain is again in the majority with single pile type foundation." first drive piles " construction method is：Steel-pipe pile is squeezed into seabed first to fix, then lifts by crane and leads
Steel-pipe pile port is inserted into jacket support leg end by pipe support, is placed to jacket, leveling and grouting, uses concrete
Steel-pipe pile and jacket support leg are bonded together, packer mainly will be between steel-pipe pile and support leg before concrete setting
Gap seal, prevent concrete from flowing out, cause bonding loosely and the waste of material such as concrete.
It is the schematic diagram of " a kind of grouting form on existing basis of first driving piles ", the sealing for sealing cement mortar shown in Fig. 1
Circle be fixed on steel-pipe pile, in this way the problem is that：When the piling length of steel-pipe pile is there are when deviation, grouting height can also be sent out
Changing；Vibrations during piling simultaneously can make the fixing bolt of sealing ring generate loosening, the weld seam of flange and steel-pipe pile
It destroys, to influence the performance of sealing ring, or even keeps its entirely ineffective；And it is dropped through sealing ring area in jacket support leg
When domain, there are the possibility that support leg and sealing ring or flange are collided, this can cause sealing ring and flange to be destroyed and fail.
Invention content
The technical problem to be solved in the present invention is to provide a kind of first stake formula packers, can solve the deficiencies in the prior art,
Improve the rigidity and survivability of packer.
In order to solve the above technical problems, the technical solution used in the present invention is as follows.
A kind of elder generation's stake formula packer, includes the cone rubber cylinder between steel-pipe pile and jacket support leg, taper rubber
It is evenly arranged with band at the top of packing element, grouting mouth is provided between adjacent ribbons, between cone rubber cylinder and jacket support leg
Cement mortar accommodating cavity is formed, cement mortar accommodating cavity is communicated with grouting mouth, and interior strips are provided with skeleton, and skeleton extends to taper rubber
The bottom of packing element, the top of band and the bottom of cone rubber cylinder are fixed by fixed mechanism and jacket support leg respectively to be connected
It connects.
Preferably, cone rubber cylinder includes the first thick section and the second thick section, the first thick section connects with steel-pipe pile
It touches, the second thick section is in contact with jacket support leg, and fixed mechanism is mounted on the second thick section.
Preferably, second thick section is evenly arranged with several flutings.
Preferably, the skeleton is flexible material.
Preferably, the skeleton is aramid fiber cord fabric or woven wire or steel cord or polyamide cord fabric.
Preferably, the laying direction of the skeleton is identical as the axis direction of jacket support leg.
Preferably, the fixed mechanism includes pressing plate and collet threaded component, collet threaded component runs through pressing plate and leads
Pipe support support leg connects.
Preferably, the collet threaded component is bolt or screw.
Preferably, the cone rubber cylinder is sector structure in a pre-installation, sector structure is provided at both ends with clinch.
Preferably, the clinch is by rivet or gluing or wears steel wire and is connected as one.
It is using advantageous effect caused by above-mentioned technical proposal：Invention increases the strength and stiffness of packer,
Have the function that strengthen sealability.Band stiffness by itself provides the sealability of Early filling stage, with the increase of grouting quantity,
Cement mortar oppresses cambered surface portion, so that cambered surface portion and the increase of steel-pipe pile laminate pressure, sealability raising, while packer is had enough
Intensity makes packer not tumble.
