Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail:
As shown in Figure 1, present embodiment has disclosed a kind of underwater dry-type repairing work cabin that is used for shallow water area, comprises vertical cabin body, and cabin body skeleton comprises four standpipes 1, is welded with the crossbeam 2 that multistage is made by channel-section steel between adjacent two standpipes 1.Body skeleton top, cabin open-ended makes cabin body open-top, and body bottom, cabin is provided with the sealing bottom door, is used to make the cabin body to straddle submarine pipeline to be keeped in repair 7.
Body skeleton four sides in cabin are welded with panel, panel directly integral solder at cabin body skeleton outer surface, also can be divided into upper panel 3 and lower panel 4 as shown in Figure 1, upper panel 3 is welded in cabin body skeleton inner surface, and lower panel 3 is welded in cabin body skeleton outer surface.Like this, make upper panel 3 be arranged at body inside, cabin, reducing cabin body volume, thereby reduce the suffered buoyancy of cabin body as much as possible; Make lower panel 4 be arranged at the cabin external body, in limited space, increased service clearance as far as possible.
The both sides of body bottom, cabin are welded with counterweight platform 6 respectively, and counterweight platform 6 is the quadras that are welded by I-steel.Also be welded with reinforced structure 12 between cabin body skeleton and the counterweight platform 6, reinforced structure 12 can be stiffening rib or deep floor etc.Above the every counterweight platform 6 balancing weight 13 is set, counterweight platform 6 and balancing weight 13 are convenient to overcome buoyancy and are carried out counterweight.Because the standpipe 1 that cabin body skeleton is four jiaos is a pipe structure, therefore when counterweight can not satisfy cabin body stability, can overcomes buoyancy and improve cabin body stability by pitching pile in standpipe 1.In addition, also can not use balancing weight 13, and come work chamber is fixed with the form of pitching pile separately.
The lower surface of every counterweight platform 6 is welded with orifice-plate type mud mat 11, and orifice-plate type mud mat 11 is steel plates of offering some through holes.Because silt is soft under water, if directly contacting with soil under water, cabin body skeleton can cause the cabin body to sink, orifice-plate type mud mat 11 has increased the area of contact of cabin body and subaqueous soil, better prevents the sinking of counterweight rear deck body.
As shown in Figure 2, being provided with that body front side, cabin and cabin body bottom rear are corresponding respectively seals side door 5, and sealing side door 5 comprises the door-plate of peripheral hardware doorframe, and doorframe is connected with cabin body lower panel 4.For the ease of installing, sealing side door 5 is formed by two-part butt joint up and down, and joint is respectively arranged with 14, two semi-circular recesses 14 of semi-circular recesses and is spliced into a circular hole, is used for submarine pipeline ccontaining to be keeped in repair 7.
Be provided with locking member around the sealing side door 5, be used to compress sealing side door 5 edges, prevent that better seawater from infiltrating.Particularly, sealing side door 5 engages three limits with lower panel 4 locking member is a hilt formula compact heap 9, and it is embedded compact heap 8 that sealing side door 5 engages locking member on one side with the sealing bottom door.
Above-mentioned hilt formula compact heap 9 comprises " L " shape press strip, the minor face end of " L " shape press strip is supported in lower panel 4, long limit is pressed on the doorframe of sealing side door 5, long limit offers a hole, the clamping bolt that is welded in lower panel 4 is passed in the silk hole, clamping bolt is furnished with nut, screws nut and makes " L " shape press strip compress sealing side door 5.Above-mentioned embedded compact heap 8 comprises " Contraband " font press strip, " Contraband " font press strip strides across the doorframe thickness of sealing side door 5, one end is embedded on the channel-section steel skeleton of sealing bottom door, the other end is pressed in the doorframe outside and is coated with clamping bolt, clamping bolt is furnished with nut, screw clamping bolt and make " Contraband " font press strip produce certain deformation, will seal bottom door and 5 lockings of sealing side door.
As shown in Figure 3, between sealing side door 5 and the submarine pipeline 7, promptly semi-circular recesses 14 inboards are provided with the linear sealing structure 15 of two projectioies, and herein linear sealing structure 15 is made by round steel, and linear sealing structure 15 is bonded with seal rubber pad; Between sealing side door 5 and the lower panel 4, also promptly seal the linear sealing structure 15 that side door 5 edges also are provided with two projectioies, linear sealing structure 15 is bonded with seal rubber pad.Like this, inside and outside twice linear sealing also cooperates the form of rubber cushion sealing, has greatly strengthened the sealing between sealing side door 5 itself and sealing side door 5 and the submarine pipeline 7, prevent that better seawater from infiltrating, easy for installation when not only using, and satisfactory for result, the reliability height.During processing and fabricating, the linear sealing structure 15 of semi-circular recesses 15 is to weld round steel respectively one section channel-section steel web both sides, afterwards channel-section steel is curved semicircle, and with channel airfoil plate and the welding of sealing side door 5 preformed holes, round steel is promptly as linear sealing structure 15 again; And sealing side door 5 be two edges of a wing by its doorframe I-steel just in time as two linear sealing structures 15, satisfy the twice linear sealing requirement between sealing side door 5 and the lower panel 4, design ingenious.
The bottom, front side and/or the bottom rear of cabin body are provided with counterweight valve 10, and counterweight valve 10 can be positioned at sealing side door 5 next doors.After the work chamber operation is finished, before unloading balancing weight 13, open counterweight valve 10, make the water in the working environment slowly enter body inside, cabin, stressed with inside and outside, balance cabin, avoid the cabin body when unloading counterweight, to float some unnecessary destructions and the trouble that causes rapidly like this, be beneficial to the work chamber lifting is reclaimed owing to be subjected to buoyancy.
The overall dimensions of cabin body (L * W * H) be controlled at usually (2m~3m) * (2m~3m) * (in the scope of 2m~12m), (L * W * H) is 2.6m * 2.6m * 9m to the cabin body size of present embodiment, can satisfy the required spatial requirement of maintenance as far as possible again when reducing cabin body volume.
The concrete fitting operation step of brief description the utility model when construction:
1, cleaning needs submarine pipeline 7 surrounding environment of maintenance, and definite soil conditions;
2, remove submarine pipeline 7 counterweight anticorrosive coats;
3, this work chamber is lifted into the seabed, straddle submarine pipeline to be keeped in repair 7 tops;
4, the sealing bottom door in installment work cabin under water;
5, work chamber is carried out counterweight or pitching pile, with sealed cabin body (if counterweight can not satisfy the stability requirement, can cooperate, also can directly fix work chamber) with pile pitching method by pitching pile;
6, the sealing side door 5 in installment work cabin under water;
7, utilize the shallow water pump with the water emptying in the work chamber, form the dry type environment;
8, work chamber feeds pressurized air, makes and forms malleation in the cabin, and the waste gas that produces during with construction is in time discharged, to satisfy workmen's operating conditions;
9, to submarine pipeline 7 cut, polish, weld, check and work such as anticorrosion;
10, work chamber reclaims.
Although in conjunction with the accompanying drawings preferred embodiment of the present utility model is described above; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment only is schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away under the scope situation that the utility model aim and claim protect, can also make the concrete conversion of a lot of forms, these all belong within the protection domain of the present utility model.
