Description
Technical field
Support technology field is fixed the present invention relates to water-bed water-bed pipeline, more particularly, to the support of water-bed pipeline suspended span
Technical field, such as submarine pipeline suspended span support technology.
Background technology
The need for communication and petroleum transportation, generally require in water-bed especially submarine laying communication and petroleum transportation pipeline,
And many factors such as out-of-flatness due to bottom surface, it is also desirable to support meanss are set at pipeline suspended span, otherwise because pipeline
Fracture can cause larger economic loss and social influence, water-bed pipeline the suspended span support such as submarine pipeline suspended span branch of prior art
Support technology typically uses following several ways：1st, sand hill is stacked below pipeline suspended span, this mode is although relatively simple, but nothing
Method forms effective permanent supporting role, performs practically no function；2nd, support base is set to fix by the way of cement grout, this mode
Engineering time is long, and completing Construction Support needs nearly 16 hours, installs trouble, and long-term hard between pipeline and support base
Friction etc., and increase the bending load of pipeline；The building-supporting equipment that this is applied to ocean engineering such as title
(CN201310083643.2), openly (announce) number be CN103114568A, the applying date be 2013.03.17 invention, it includes
Chassis, firm banking, lead column, support tube and support platform are floated, firm banking is fixed on floating chassis, lead column connection
On firm banking, support tube is enclosed within outside lead column, and the gap between support tube and lead column forms mixed mud and pours chamber, is supported
Platform is fixed at the top of support tube.Floating chassis is floated across the sea, while making the fixation of mixed mud on floating chassis
Base, lead column, then support tube is enclosed within outside lead column, whole equipment is still floated across the sea, is then poured into mixed mud and is poured
Build in chamber, when gravity is more than the buoyancy on floating chassis, seabed is sunk on floating chassis, and lead column and support tube length are more than place
What is be located in is sea water advanced, after sinking to seabed completely after floating chassis, continues to pour into mixed mud in chamber toward pouring, then by support platform
It is fixed at the top of support tube, support platform is used to carry offshore engineering equipment.Above-mentioned this structures and methods, equally there is
Disadvantages mentioned above；3rd, by the way of hydraulic pressure support, such as patent name is a kind of structural support for being used to handle submarine pipeline suspended span
Device (CN201510766775.4), openly (announce) number be CN105333227A, the applying date be 2015.11.11 invention it is special
Profit, it include head hydraulic system, main supporting plate, the main telescoping cylinder in leg, mud mat, the lateral telescoping cylinder of supporting leg, grasping mechanism,
Driving cylinder, locating rod, lifting cylinder, oil pipeline, hanger etc. are captured, main telescoping cylinder and lateral telescoping cylinder, which coordinate, realizes overall structure
The lifting of support meanss and angle adjustment, grasping mechanism lifting are controlled by lifting cylinder, and pipeline is determined by locating ring before crawl pipeline
With the distance of grasping mechanism, what crawl driving cylinder control hand was grabbed opens and closes, the pipeline quilt when paw connecting rod is contacted with block
Clamp and realize self-locking, it is ensured that the reliability of clamping.Although this mode is with structure than foregoing second way construction time phase
To shortening, but its high cost, the construction period still needs the relatively long time,
