Abstract
The purpose of the present invention is to provide a kind of tortoise shape flexibility submerged pipeline clump weight, counterweight block body is turtleback, and turtleback can effectively reduce the horizontal force of flow；Clump weight body lower part is equipped with several tortoises foot, tortoise is equipped with to overhanging toe can be inserted into seabed enough, side-friction can be increased, increase pipeline lateral stability, counterweight block body is equipped with flexible pipe line channel, flexible pipe line is covered with rubber pad in channel, rubber pad increases the friction of counterweight block body and flexible pipe, reduce sliding of the counterweight block body on flexible duct, counterweight block body is divided into dismountable two pieces up and down, upper and lower two pieces are bolted, and upper and lower two pieces are centrally formed flexible pipe line channel when being bolted together.It is good in submarine laying flexible pipe line stability of channel the beneficial effects of the invention are as follows simple in structure.
Description
Technical field
The invention belongs to undersea pipe-laying technical fields, are related to a kind of tortoise shape flexibility submerged pipeline clump weight.
Background technology
Flexible submarine pipeline such as PE pipelines, tubing relative density is smaller than seawater, and pipeline can under the conditions of full water
Floating so must add enough clump weights in submarine laying flexible duct can just make its sinking, and is anchored on design routing
On.For the flexible duct for not requiring trench-digging to set, pipeline can be acted on by flow force and wave force, more pipeline be made to float easily
It rises, is detached from its position, loses its stability in place.General rectangle clump weight, shape itself can increase the active force of flow,
It is unfavorable for the stabilization of pipeline.Round clump weight, friction coefficient is smaller, is usually used in groove, for the pipeline of not ditching, stability
It is bad.
Invention content
The purpose of the present invention is to provide a kind of tortoise shape flexibility submerged pipeline clump weights, and the beneficial effects of the invention are as follows structures
Simply, good in submarine laying flexible pipe line stability of channel.
The technical solution adopted in the present invention be include counterweight block body, counterweight block body is turtleback, and turtleback can have
Effect reduces the horizontal force of flow；Clump weight body lower part is equipped with several tortoises foot, and tortoise is equipped with to overhanging toe can be inserted into enough
Seabed can increase side-friction, increase pipeline lateral stability, and counterweight block body is equipped with flexible pipe line channel, flexible pipe line
Rubber pad is covered in channel, rubber pad increases the friction of counterweight block body and flexible pipe, reduces counterweight block body in flexible duct
On sliding, counterweight block body is divided into dismountable two pieces up and down, and upper and lower two pieces are bolted, and upper and lower two pieces pass through bolt
Flexible pipe line channel is centrally formed when linking together.
Description of the drawings
Fig. 1 is tortoise shape flexibility submerged pipeline clump weight side schematic view；
Fig. 2 is tortoise shape flexibility submerged pipeline clump weight front schematic view.
In figure, 1. counterweight block bodies, 2. tortoises foot, 3. flexible pipe line channels, 4. rubber pads, 5. bolts.
Specific implementation mode
The present invention is described in detail With reference to embodiment.
A kind of tortoise shape flexibility submerged pipeline clump weight of the present invention is as depicted in figs. 1 and 2, including counterweight block body 1, counterweight
Block body 1 is turtleback, and turtleback can effectively reduce the horizontal force of flow；1 lower part of counterweight block body is equipped with several tortoises foot
2, tortoise foot 2, which is equipped with to overhanging toe, can be inserted into seabed, can be effectively increased side-friction, increase pipeline lateral stability,
Counterweight block body 1 is equipped with flexible pipe line channel 3, is covered with rubber pad 4 in flexible pipe line channel 3, rubber pad 4 can increase
Add the friction of counterweight block body 1 and flexible pipe, reduces sliding of the counterweight block body 1 on flexible duct.Counterweight block body 1, which divides, is
Dismountable two pieces up and down, upper and lower two pieces are connected by bolt 5, and upper and lower two pieces are centrally formed when being linked together by bolt 5
Flexible pipe line channel 3 is connected flexible submerged pipeline by upper and lower two pieces direct flexible pipe line channels 3 when use with bolt 5
Counterweight block body 1 is sunk to seabed by good counterweight block body 1, and the toe of the tortoise foot 2 of counterweight block body 1 is inserted into seabed, completes flexible
The submarine laying of pipeline passway 3.
The above is only the better embodiment to the present invention, not makees limit in any form to the present invention
System, every any simple modification that embodiment of above is made according to the technical essence of the invention, equivalent variations and modification,
Belong in the range of technical solution of the present invention.
