{RELEASING PREVENTING BLOCK FOR MARINE PIPE}

The present invention relates to a marine pipe flotation prevention block, and more particularly, it relates to a marine pipe flotation prevention block, which is capable of preventing airtightness of a pipe joint while preventing floating of the pipe, Shaped file is fixedly installed on the upper surface of the water pipe so as to prevent the water pipe from being easily floated against the lift force.

In general, pipelines are installed on the seabed when pipelines, gas pipelines or water pipelines cross continents and continents or continents and islands across the sea. As a cooling water for the power plant, a pipeline is laid down to the sea floor to get low temperature seawater.

Pipelines of pipelines, gas pipelines, gas pipelines, water supply pipelines, and power plant intake pipelines have a diameter of at least 2 m and a length of several tens of meters or more and are large in size and work in the sea. Therefore, natural conditions such as wind, tide, There are a lot of restrictions on the work of laying.

As a method for laying offshore pipelines, a bottom-pooling method is known widely, in which pipelines constructed onshore are pulled down to the seabed.

Conventional subsea pipeline laying method using a submarine pulling method is a method in which pipelines are formed by continuously welding pipes seated on a series of bogies in a workshop on the ground and pulling pipelines from the barges on the sea, As the cargo moved to sea, the pipeline was settled down to the seabed.

However, as mentioned above, pipelines installed on the sea floor may flow or float due to algae, waves or other external forces, and a means for preventing the flow of pipelines installed on the sea floor is urgently required.

As a prior art for solving the above problems, Korean Patent Application Publication No. 10-2011-078286 (name: marine pipe lifting prevention block) (hereinafter referred to as prior art) can be exemplified .

The present invention relates to a marine pipe flotation prevention block installed on the sea floor, comprising a block body having a rectangular shape, a pipe body through which a marine pipe is inserted, And a plurality of flushing fins detachably fitted in the fitting hole, wherein the fitting holes are formed on the both sides of the block body so as to be vertically spaced apart from each other by a predetermined distance, So that it can be fitted in any one of the fitting holes.

However, the pipes installed in the seabed are usually connected to each other in a state where they are connected to each other in a state where they are connected to each other in a unit of a pipe having a length of about 6 m. The prior art block may have the effect of preventing the floating of the pipe, A separate airtight means must be attached to the connection portion of the pipe and the pipe, and the operation of attaching the airtight member is performed in the deep sea floor, which causes a lot of inconvenience to work.

Specifically, the upper block 110 has a rectangular parallelepiped shape, and semicircular first and second insertion grooves 112a and 112b are formed in the lower surface thereof. The first and second insertion grooves 112a and 112b are formed in the main pipe 100 And the spare pipe 200, respectively.

A fastening hole 114 is vertically formed at both sides of the upper block 110 and a lower block 120 positioned below the upper block 110 is inserted into the upper block 110 as the fastening hole 114. [ A bolt 116 serving as a fastening means for fastening and fastening the bolts 116 is provided.

The lower block 120 is a block located below the upper block 110 and has a rectangular parallelepiped shape and has semicircular first and second insertion grooves 122a and 122b recessed from the upper surface thereof. The main pipe 100 and the spare pipe 200 pass through the first and second pipes 122a and 122b, respectively.

A coupling groove 124 is formed on both sides of the upper surface of the lower block 120. The coupling groove 124 is fixedly installed in a state of being fitted with a nut 126 by welding or the like.

A bolt 116 inserted through the fastening hole 114 of the upper block 110 is fastened to the nut 126 inserted into the fastening groove 124 of the lower block 120, And the upper and lower blocks 110 and 120 that surround the outer surface of the preliminary pipe 200 are fastened and fixed to each other.

The main pipe 100 and the main pipe 100 and the auxiliary pipe 200 and the auxiliary pipe 200 are arranged to be opposed to each other at the time of assembling the marine pipe flotation prevention block composed of the upper and lower blocks 110 and 120 having the above- I.e., the connecting portion 102 of the main pipe 100 and the connecting portion 202 of the spare pipe 200. [ And the upper and lower blocks 110 and 120 are connected to each other so that the connection parts 102 of the main pipe 100 are inserted into the insertion grooves 112 and 122 of the upper and lower blocks 110 and 120, And the bolt 116 is passed through the fastening hole 114 of the upper block 110 in this state, the bolt 116 is inserted into the fastening hole 114 of the upper block 110, The connecting portion 102 of the main pipe 100 and the connecting portion 202 of the auxiliary pipe 200 are fastened to the nut 126 inserted into the fastening groove 124 formed on both sides of the upper surface of the upper pipe 120, The upper and lower blocks 110 and 120 are connected and fixed to each other.

On the inner circumferential surfaces of the first and second insertion grooves 112a and 112b of the upper block 110 and the inner circumferential surfaces of the first and second insertion grooves 122a and 122b of the lower block 120, , 128 are installed. The upper and lower packing members 118 and 128 are connected to the insertion grooves 112a, 112b, 122a and 122b of the upper and lower blocks 110 and 120 with the connection portions of the main pipe 100 and the spare pipe 200 The upper and lower packing members 118 and 128 provided on the inner circumferential surfaces of the insertion grooves 112a and 112b and 122a and 122b are inserted into the connection portion 102 of the main pipe 100 and the auxiliary pipe 200 So that leakage is prevented from occurring in the connection part 102 of the main pipe 100 and the connection part 202 of the spare pipe 200 .
