2, cofferdam scheme comprises steel sheet-pile cofferdam and sandstone cofferdam.Steel sheet-pile cofferdam is restive at the sheet pile construction precision, has both caused the big shutoff difficulty in space between sheet pile, may damage pipeline again.Sandstone cofferdam materials enormous amount, the duration is very long, and investment is big, and jackstone may damage pipeline.Cofferdam structure is difficult to remove after maintenance.
Three, summary of the invention
The purpose of this utility model provides a kind of submarine pipeline maintenance construction case, overcome the defective that above-mentioned prior art exists, can safety, reliably, easily treat maintenance department and the seawater of submarine pipeline are isolated, the working environment of formation relatively dry is so that satisfy operation needs such as pipeline welding repairing.
The technical solution of the utility model realizes in the following manner:
The utility model is made up of casing, valve, fixing stake and wave suppression plate structure, it is characterized in that bottom surface does not seal on the casing, opens the inverted U notch in casing front and back sides bottom, so that the submerged pipeline that needs maintenance is embedded wherein; Inboard about the middle part of casing, along continuous straight runs is provided with splits the cone valve, be slidingly matched with case, valve is connected one by bearing pin with the bearing pin seal plate, be arranged with 6 suspension ring in valve inwall bottom, be to have to open and close the wire rope that valve is used on the suspension ring, 6 wire rope symmetries are connected on the center ring; Between valve and maintenance casing, valve and pipeline, two fan valve closing faces, casing and pipeline, respectively be provided with sealing surface; The external side of service kit is provided with stiffening rib, at the welding box-shaped beam in the outside of the left and right sides, casing upper end portion, be provided with the fixing stake guide cylinder of symmetry on vertical in the end of box beam, fixing stake is squeezed into the seabed by guide cylinder, and fix with guide cylinder, be provided with valve centralized positioning plate in casing left and right sides upper center, positioning plate is provided with center hole, the steel wire penetrating center hole of valve opening and closing device is connected with center ring, establish wire rope locking device above the center hole, service kit is provided with the wave suppression plate that is nested with it around the top, and service kit inside is provided with ladder, operating platform, exhaust column.
Have the arc groove of symmetry in valve apposition position upper end.
Compared with the prior art the utility model has the following advantages:
1, the pipeline that is in the seawater can be waited to repair position and seawater isolation, form the working environment of relatively dry, satisfy the needs that impaired pipeline carried out dry type repair by welding operation.
2, service kit is by four fixing stake location and fixing, and by the environmental load that fixing stake is born the casing deadweight and is subjected to, casing can not cause damage to extra large pipe.
3, use is simple to operate, and workload and the facility negligible amounts of employing can the rapid deployment construction operations.
4, remove conveniently the maintenance back, can not cause change to pipeline's surrounding environment.
5, can reuse, be fit to the pipeline of different-diameter, for the maintenance of submarine pipeline offers convenience.

Five, embodiment
For further disclosing the technical solution of the utility model, be described in detail by embodiment below in conjunction with Figure of description:
The utility model is made up of with wire rope 10 maintenance casing 1, fixing stake 2, valve 3, box beam 4, fixing stake guide cylinder 5, bearing pin seal plate 6, bearing pin 7, false bottom seal plate 9, lifting, it is characterized in that bottom surface does not seal on the casing, open the inverted U notch in casing front and back sides bottom, so that the submerged pipeline that needs maintenance is embedded wherein; Inboard about the middle part of casing, along continuous straight runs is provided with splits the cone valve, be slidingly matched with case, valve is connected one by bearing pin with the bearing pin seal plate, be arranged with 6 suspension ring in valve inwall bottom, be to have to open and close the wire rope that valve is used on the suspension ring, 6 wire rope symmetries are connected on the center ring; Between valve and maintenance casing, valve and pipeline, two fan valve closing faces, casing and pipeline, respectively be provided with sealing surface; The external side of service kit is provided with stiffening rib, at the welding box-shaped beam in the outside of the left and right sides, casing upper end portion, be provided with the fixing stake guide cylinder of symmetry on vertical in the end of box beam, fixing stake is squeezed into the seabed by guide cylinder, and fix with guide cylinder, be provided with valve centralized positioning plate in casing left and right sides upper center, positioning plate is provided with center hole, the steel wire penetrating center hole of valve opening and closing device is connected with center ring, establish wire rope locking device above the center hole, service kit is provided with the wave suppression plate that is nested with it around the top, and service kit inside is provided with ladder, operating platform, exhaust column.
