Abstract
The utility model provides a mud sand-rushing device for maintaining a submarine pipeline, which can be used for rushing the mud sand when a submarine pipeline and a submarine cable pipeline are maintained, can effectively avoid the back settling, and can meet the construction requirement under the condition of large embedded depth. The device comprises a water supply pipe, wherein a gas supply pipe and the water supply pipe are fixed outside a mud discharge pipe; and the front end of the water supply pipe is provided with a nozzle assembly, the nozzle assembly is welded at the front of the mud discharge pipe, and the front end of the gas supply pipe penetrates through the nozzle assembly and is bent towards the inner of the mud discharge pipe. The gas supply pipe offers high-pressure gas, so that the mud sand is discharged to a far place through the mud discharge pipe, and the back silting can be avoided. The mud sand-rushing device is simple in structure and convenient to operate, a plurality of nozzles can be welded on the nozzle assembly, the mud sand-rushing device is high in rushing capability, the rushed mud sand can be discharged to the far place through the mud discharge pipe by the negative pressure generated by the high-pressure gas provided by the gas supply pipe, and the problem such as the back silting caused by rushed mud sand can be effectively solved. The large-embedded-depth pipeline can not be reburied by the rushed mud sand even if being rushed to remove the mud sand, so that the construction efficiency can be improved.
Description
Technical field
The utility model belongs to the underwater maintenance equipment of submarine pipeline, and particularly submarine pipeline maintenance is towards the silt particle device, dashes the silt particle operation when can be used for submarine pipeline, submarine cable pipeline maintenance, can effectively prevent to back-silt, and satisfies the construction requirement under the big buried depth situation.
Background technology
Embedding manner is all adopted in the laying of submarine cable pipeline at present, all need be towards the silt particle operation in the maintenance process in later stage.Currently dash silt particle operation, the mode that all adopts giant to fling for submarine pipeline.Use this kind mode towards the silt particle clearing of pipeline, low, the length consuming time of constructing of its efficiency of construction.Owing to just silt particle is washed open,,, can't do not satisfied the construction requirement under the big buried depth situation so can not prevent effectively to back-silt with silt particle suction displacement.
Summary of the invention
The purpose of the utility model provides submarine pipeline maintenance towards the silt particle device, solves towards the silt particle operation to back-silt and towards the problem of silt particle depth as shallow.Improve operating efficiency, satisfy pipeline under the big buried depth situation towards the construction requirement of silt particle.
The technical solution of the utility model is: the submarine pipeline maintenance comprises feed pipe towards the silt particle device, and air supply pipe and feed pipe all are fixed on the outside of mud pipe; The front end of feed pipe is an injector assembly, and injector assembly is welded on the front portion of mud pipe, and the front end of air supply pipe passes from injector assembly and bends towards in the mud pipe.Air supply pipe provides gases at high pressure, and silt particle is drained at a distance through mud pipe, avoids back-silting.
Compared with prior art; The utility model is simple in structure, easy to operate, has following useful effect, on injector assembly, can weld a plurality of nozzles; It is strong to wash away ability; The negative pressure that the silt particle of being washed open can be produced by the gases at high pressure that air supply pipe provides drains at a distance through mud pipe, efficiently solves the problem of back-silting towards silt particle.Even towards silt particle, the silt particle that its pipeline also can not be washed open is buried once more, has improved efficiency of construction, has tangible economic benefit to the pipeline of big buried depth.
