Large-diameter sea area pipeline notching device and groove forming method
The invention relates to a large-diameter sea area pipeline notching device. The large-diameter sea area pipeline notching device comprises a notching device steel frame which is arranged on a sea area pipeline and provided with a traction part, and a sea area pipeline containing space used for containing the sea area pipeline is formed at the bottom of the notching device steel frame; spraying and scouring pipes capable of scouring seabed bottom mud are arranged on the two sides of the sea area pipeline containing space, and a water pumping mechanism capable of supplying water to the spraying and scouring pipes is arranged on the notching device steel frame; ditching arms capable of guiding the spraying and scouring direction of the spraying and scouring pipes are further arranged on the two sides of the sea area pipeline containing space, and the ditching arms are located below the spraying and scouring pipes; The large-diameter sea area pipeline notching device further comprises straightening devices mounted on the two sides of the notching device steel frame. Seabed bottom mud below the to-be-embedded pipeline can be scoured through the water pumping mechanism and the spraying and scouring pipes, so that pipeline burying, notching and ditching construction operations after pipeline laying in a sea area are performed, the construction progress is accelerated, and a silt back-silting phenomenon after ditching is avoided.
本发明的一种大直径海域管道冲槽装置，包括置于海域管道上且具有牵引部的冲槽装置钢架，冲槽装置钢架的底部形成用于容纳海域管道所设的海域管道容纳空间；在海域管道容纳空间的两侧设有可对海床底泥进行冲刷所设的喷冲管，所述的冲槽装置钢架上设有可对喷冲管进行供水所设的泵水机构；在海域管道容纳空间的两侧还设有可对喷冲管喷冲方向进行导向所设的开沟臂，开沟臂位于喷冲管的下方；还包括安装在冲槽装置钢架两侧的扶正装置；通过泵水机构和喷冲管可以对待预埋管道下方的海床底泥进行冲刷，以此进行海域管道铺设后的管道埋设冲槽挖沟施工作业，加快了施工进度，并且不会出现挖沟之后的泥沙回淤现象。
