Technical field
The present invention relates to ocean sealing skirt pile sleeve installing area, more particularly to a kind of fiber for being used to seal skirt pile sleeve
Strengthen barrier film and moulding process, belong to composite structure device formation technical field.
Background technology
The installation of water is typically installed using Shipping under current ocean jacket, skirt pile sleeve and stake, with sea
A large amount of exploitations of foreign petroleum resources, its jacket, skirt pile sleeve and the volume and weight of stake are constantly increasing, and Shipping is not only
Construction costs is only increased, ample resources is also wasted；Fiber reinforcement barrier film is the sealed skirt in the pioneering application Yu Haiyang of China
The installation of water under pile protection cylinder progress jacket, skirt pile sleeve and stake.The fiber reinforcement barrier film uses the electrodeless hole geodetic of continuous fiber
Line winding shaping process, achievable dry fibers continuously strengthen, and fiber reinforcement barrier film can obtain more stable structure；The production technology
It is high with production efficiency, raw material are saved, Forming Quality is high, and product structure is stable, flexible, is difficult layering, light weight, life-span
Long, reliability is high, the excellent properties such as central area is easily punctured.
Most of sealing barrier film is using multilayer rubber structure at present and is generally to lay multilayer cord fabric by hand again through vulcanizing shape
Into.Also small part moulding process is Wrapping formed using being interrupted by fiber cord fabric, and is generally to carry out by hand.Its two kinds into
Type mode production efficiency is low, and shaped article quality is poor, easily layering, and structural instability, discontinuity is low using reliability,
The air-tightness and globality of its product can not ensure.
CN102261463A discloses a kind of long-life rubber diaphragm, and its diaphragm of rubber is made up of diaphragm and barrier film screw.
Diaphragm is overlapped by rubber slab and impregnation polyamide fibre screen cloth, and wherein rubber slab and a piece of impregnation polyamide fibre screen cloth are located at barrier film screw
Ailhead below, remaining rubber slab and impregnation polyamide fibre screen cloth pass through barrier film screw bar portion and are stacked and placed on above ailhead, then through molding
Vulcanization；It is poor to there is Forming Quality in long-life rubber diaphragm, easily layering, the serious problems such as structural instability, so that stress when in use
Uneven, influence is entirely sealed every film strength and service life；Its technological process of production is complicated, labor intensity is big, production effect
Rate is low, and the diaphragm of rubber is difficult to meet the installation that sealing skirt-structurE carries out water under ocean jacket, skirt pile sleeve and stake.
The content of the invention
It is an object of the invention to solve sealing diaphragm forming technique, to there is labor intensity big, low production efficiency, structure easy
There is provided a kind of fiber reinforcement barrier film and moulding process for being used to seal skirt pile sleeve, its work for the problems such as layering and service life are short
Dry fibers are wound skill into dry fibers enhancement layer and polyurethane gel cladding dry fibers enhancement layer solidify to form two kinds of protective layer
Moulding process is effectively combined, and gives full play to material and winding process each characteristic；Its product flexibility is good, light weight, saving former material
Material, long lifespan, enhancing structure are stable, central area is easily punctured, in equivalent specifications product its product can bear it is high-quality substantially
The installation of water under long-pending skirt-structurE.
A kind of fiber reinforcement barrier film for being used to seal skirt pile sleeve, wherein the next enhancing barrier film is wound by dry fibers
Dry fibers enhancement layer and polyurethane gel cladding dry fibers enhancement layer curing molding protective layer are constituted for two layers.
A kind of fiber reinforcement barrier film and moulding process for being used to seal skirt pile sleeve, is first adopted dry fibers by wind
With continuous electrodeless hole Geodesic winding moulding process, winding fiber is covered with mandrel surface, forms dry fibers enhancement layer；Secondly
Polyurethane glue is coated into dry fibers enhancement layer, progress solidify to form protective layer；Finally the fiber reinforcement barrier film after solidification is entered
The row demoulding.
Described core is that with thread-laying device mould, and bottom has on the dry fibers transition zone extended internally, transition zone
The Needle with hanging thread being circumferentially arranged in order is provided with as winding revolving support point, the electrodeless hole geodesic curve of continuous fiber is easy to implement and twines
Around moulding process.
The electrodeless hole Geodesic winding moulding process of described continuous fiber, according to the skirt-structurE of specified specification, to determine
Dry fibers wind the number of plies（Such as 10-12 layers）And winding tension（Such as identical tension 50N）Deng technological parameter；It winds the number of plies and winding
Two kinds of technological parameters of power are mutually used, it is ensured that fiber reinforcement seals barrier film each point bearing capacity；The sealed skirt encapsulation of different size
The different electrodeless hole Geodesic winding mode of cylinder selection.
The number of plies of the dry fibers enhancement layer and the thickness of protective layer can be set according to skirt pile sleeve specification size；Institute
While stating protective layer and can improve fiber reinforcement barrier film bearing capacity, the dry fibers enhancement layer of fiber reinforcement barrier film is also protected.
Beneficial effects of the present invention：Because fiber reinforcement barrier film uses the electrodeless hole Geodesic winding moulding process of continuous fiber
Winding is covered with mandrel surface formation dry fibers enhancement layer, so as to obtain more stable enhancing structure, you can bear more substantially
Product and heavier skirt pile sleeve jacket；Dry fibers enhancement layer is coated by polyurethane glue, curing molding formation protective layer can
Realizing strengthens the sealing of fiber reinforcement barrier film, the also protection to dry fibers enhancement layer；Fiber reinforcement diaphragm forming technique can
Using automatic processing, its processing efficiency is higher than lay rubber cord fabric by hand, enhancing structure is more steady than laying rubber cord fabric structure
It is qualitative good, it is less prone to layering and ruptures.The product flexibility is good, light weight, saves raw material, and cost is low, and service life is long, increases
Strong structure is stable, the certainly floating lower water operation of sealing skirt pile sleeve can be achieved, after installing in place, center is easily punctured, without prejudice to piling
Work, and skirt pile sleeve is provided with the readily removable fixing tool removed, it can provide convenient for later stage skirt piles jacket dismantling operation,
Construction costs is substantially reduced, the fiber reinforcement barrier film for sealing skirt pile sleeve can be recycled, reach environmental requirement；With steady
Determine enhancing structure and good sealing, more volume can be born and heavier skirt pile sleeve jacket.
