Abstract
A kind of integral type submarine pipeline suspended span restraining device, including：For to submarine pipeline carry out stability counterweight, covering protection and several counterweight blocks of cross processing, by several counterweight attachment devices that several counterweight blocks link together, the unhurried current Anti-scouring device being separately mounted in several counterweight attachment devices, loaded filter device in several counterweight blocks and counterweight attachment device bottom is set; wherein, which includes：Several pedestals, the artificial cursive script being vertically set on pedestal；The counterweight attachment device is equipped with：Several connecting rods of counterweight bulk inner are separately positioned on, which is connected as one；The artificial cursive script is separately mounted on several connecting rods；Several counterweight blocks are docked with several connecting rods and are integrated again.The present invention not only enables submarine pipeline wash away with inhibiting ocean underflow, solves the problems, such as or slow down long-term suspended span risk and harm caused by submarine pipeline；Moreover, improving the efficiency of operation on the sea.
Description
Technical field
The present invention relates to submarine pipeline more particularly to a kind of integral type submarine pipeline for administering submarine pipeline suspended span are outstanding
Across restraining device.Belong to ocean engineering field.
Background technology
Submarine pipeline is the core component in marine oil gas field development engineering.Currently, due to complexity such as seabed scourings
There is hanging phenomenon in the influence of environment, more and more submarine pipelines so that submarine pipeline receives seriously threaten safely, sea
The pipe suspended span improvement of bottom sea has become a urgent problem.
To solve the above-mentioned problems, the measure of the hanging improvement of existing submarine pipeline includes：Underwater stub supporting methods, water
The methods of lower support fixation, flexible hose bridging method, geotextiles method, bionic aquatic weed flexible protective method and briquetting covering protection；
But above-mentioned these method regulation effects are unsatisfactory.Since operation on the sea quantities is larger, construction cost is higher；And
Since long-term regulation effect is bad, cause it that need to carry out repeatedly project treatment repeatedly, it can not the extra large pipe suspended span of once and for all solution
Problem.
Invention content
It is a primary object of the present invention to overcome disadvantages mentioned above of the existing technology, and provide a kind of integral type Submarine Pipeline
Suspended span restraining device in road not only enables submarine pipeline wash away with inhibiting ocean underflow, solves or slow down long-term suspended span pair
Risk caused by submarine pipeline and harm problem；Moreover, being obviously improved the efficiency of operation on the sea, construction risk and expense are reduced
With.
The purpose of the present invention is what is realized by following technical scheme：
A kind of integral type submarine pipeline suspended span restraining device, it is characterised in that：Including：For carrying out stability to submarine pipeline
Counterweight, covering protection and several counterweight blocks of cross processing, by several counterweight blocks link together it is several with reconnection
Device, the unhurried current Anti-scouring device being separately mounted in several counterweight attachment devices, setting in several counterweight blocks and match reconnection
The loaded filter device of connection device bottom, wherein the unhurried current Anti-scouring device includes：Several pedestals are vertically set on pedestal
Artificial cursive script；The counterweight attachment device is equipped with：Several connecting rods of counterweight bulk inner are separately positioned on, several connecting rods
Part is connected as one；The artificial cursive script is separately mounted on several connecting rods；Several counterweight blocks again with several connecting rods
Part docking is integrated.
It is connected and composed as reticular structure between several pedestals.
The connecting rod is the frame-type knot being made of several vertical steel skeletons and several circumferential steel connecting rods
Structure.
The loaded filter device is connected and composed by the high-strength woven fabric of anti-filter and wound and bound rope, for slowing down flow velocity, fixing the sand, and is promoted
It becomes silted up.
Beneficial effects of the present invention：The present invention due to the adoption of the above technical scheme, not only enables submarine pipeline to inhibit
It washes away to ocean underflow, solves the problems, such as or slow down long-term suspended span risk and harm caused by submarine pipeline；Moreover, significantly carrying
The efficiency for having risen operation on the sea, reduces construction risk and expense.
