Description

Snag structure dry type handling labor cabin and operation ship thereof

The present invention relates to underwater structure (being made by steel or concrete material), particularly safeguard with dry-type working cabin and transport operation ship thereof the tidal range region.

Development along with marine cause and sea-freight, structures are used more and more widely in the water, for example: marine oil drilling platform piling bar or the like under water of piling bar, inland river or coastal dock (or trestle) under water, these are the anticorrosion problem that just becomes a necessary attention day by day of the pilework of (particularly under the seawater) under water.These underwater structures generally adopt coating (the topped thing of anti-corrosion paint or resin under water) in advance during fabrication, and measures such as cathode protection are set under water protect.And in the tidal range region; promptly at the incoming tide under water; and this a part of pilework that surfaces during ebb tide then can't adopt cathode protection, and; this part is easy to be subjected to ultraviolet irradiation, ozone chemistry effect; the fresh water (or seawater) that also is subjected to containing saturated oxygen splashes and the impact of wave, and the bump of floater, therefore; filming when pilework is made is impaired easily, causes its base material to be easy to be corroded.

At present, generally be after after a while to filming of tidal range band pilework, again coated once, method is to adopt the coating of constrictive type under water, its kind has polyamide solidified type epoxy class or polyester-type etc.By diver's brushing such as trowel method or roller method by hand that pulls the plug, but this method relatively is suitable under water or in the more clear water of water quality of fresh water, if in the higher or muddy seawater of silt content, then because the unclear quality that will influence brushing greatly of sight line; And brushing materials amount also big (general coating is more sticking) in the water, loss are also big.This is not optimal scheme! Also having, is to establish framedly in the steel pipe pile outer ring as " the framed antisepsis of steel pipe pile " of the clear 61-102919 of Japanese Patent, injects the water hardening resin, makes its sclerosis back form preservative coat; And for example British patent 1494072, and its method is to adorn an overcoat around stake, and polyethylene is injected in the space between venting stake and the overcoat, forms a protective cover, and these methods all have its limitation.

Essential characteristic of the present invention is, the expensive expense of avoid brushing anticorrosive paint under water, saving diver's underwater operation also needn't be with special cured coating under water; But, tidal range region in pilework, make the dry type environment of a part, in this dry type environment, operating personal can be checked the quality of the original coating of pilework, reject the stump of original coating and the pilework surface carried out operations such as drying, and in the dry type environment, under situation about detecting by an unaided eye, anticorrosive paint is under water brushed on the pilework surface, to guarantee the brushing quality of anticorrosion coating, reach the anticorrosion maintenance of special quality snag structure, no matter be tidal range band or certain degree of depth district under water.

The present invention is made of three parts, and a part is the dry type handling labor cabin of pilework being realized the local dry-type environment; Another part is to make the handling labor cabin adapt to the interlock door frame of various differing heights needs and piles with different locations of structures needs; Third part is work chamber to be transported and the operation ship of mobile usefulness.Work chamber is (when pilework is the garden tubular) as shown in Figure 1, it is by fixed body 2 and left mobile 19, right mobile 23 constitutes a left side, each is connected by four hinges between right mobile and the fixed body, the folding of two mobiles is realized by left folding oil cylinder 4 and right folding oil cylinder 14, making work chamber and pilework centering location is to realize radially fixing by four following radial location devices 7 and four last radial location devices 18, following radial location device is fixed, realize (seeing the part 3 among Fig. 2) by bolt rubber, last radial location device then is adjustable, as Fig. 3, it is to realize fixing and dismounting by the rubber of ram cylinder (Fig. 3 spare 7) drive top board (Fig. 3 spare 1) front end.Near pilework transported to work chamber by the operation ship; embrace pilework and by last by two mobiles and fixed body; following radial location device is after radial location; upward axial jacking mechanism 20(can be by manual leading screw or air pressure to regulate two; oil hydraulic cylinder is realized); make it to withstand on the end face equipment or platform of pilework; make work chamber can overcome buoyancy unlikely on; under float; at this moment; energized; start the diving pump 9 of work chamber bottom the ponding in the cabin is discharged work chamber by discharge port; combination sealing arrangement shown in Figure 2 is adopted in sealing between work chamber bottom and the pilework; it is by opotism formula sealed skirt 1; connect base plate 2; following radial location device 3; elastic sealing device cladding 4 and this high elastic rubber of high elastic rubber 5(are high bipeltate; outer wearing layer again) forms; its sealing is by rubber and high elastic rubber 5 on the following radial location device 3; surrounding the pilework periphery realizes; if the pilework periphery is with cable; cable is during with channel-section steel or other supplementary structure; because the toughness of high elastic rubber protection; can realize preferably that still the sealing between work chamber bottom and the pilework is (if poorly sealed; cause some infiltration; as long as unit time internal drainage amount surpasses water percolating capacity, can form the dry type environment in the work chamber equally).After the dry type environment in the work chamber formed, operating personal can enter space in the work chamber from hand-hole, and it is collapsible to stand in upper footboard 15() or steel net plate 10 on clear up, the operation of dry pilework and brushing anticorrosion coating.For alleviating influence to operation ship balance, improve safe reliability, on work chamber, be provided with 8 air tanks, make work chamber have certain buoyancy (3 among Fig. 1 and 5), the section structure of this work chamber should constitute with steel, and the combination shape cabin body of the also available antiseep canvas of more small-sized work chamber or glass-felt plastic and steel constitutes.And, in order to be suitable for the anticorrosion of a large amount of pileworks, should be behind the anti-corrosion treatment of finishing a pile structure, work chamber is moved to rapidly on another pile structure, and therefore, side is equipped with four self-locking type hooks outside work chamber fixed body 2, see Fig. 4, it is made of catch gear 1, hook body 2, shackle 3 and locating dowel pin 4, and after work chamber hung on the operation ship interlock door frame, shackle 3 will be anchored on work chamber on the interlock door frame automatically.
