Abstract
The present invention relates to protecting sinker rank for submarine pipeline and its making process. The protecting sinker rank consists of modules and connecting rope, and each of modules consists of two, one upper and one lower, superposed cuboid blocks. At least 6 modules are arranged in the long axis direction, at least 4 modules are arranged in the short axis direction, and modules are connected with connecting rope to constitute the soft protecting sinker rank. The protecting sinker rank is sunk to cover the submarine pipeline for preventing the erosion of ocean current to the sea bed and preventing the damage of anchor to the pipeline.
Description
Technical field:
The present invention relates to a kind of protection sinking mattress and manufacture method thereof of submerged pipeline.
Background technique:
Along with the progress of engineering under the ocean water, the offshore oil production technology is promoted widely, is finding that along the vast shore line of China the many places offshore oilfield is arranged, and submarine cable/pipeline is widely used.But, the cable of existing floating pipe line, gas pipeline and some seabed broadband connectionss, because they are laid on the sea bed in seabed, because environment is slightly disliked in the seabed, sometimes current can fall the seabed scouring under pipeline and the cable, make section of tubing and cable be in hanging shape, have in addition be moved the position, influenced the safety in production of offshore oil production industry and seabed broadband connections to a certain extent.
Summary of the invention:
The purpose of this invention is to provide protection sinking mattress of a kind of submerged pipeline and preparation method thereof, be used for the fixing or protection of pipeline cable on the sea bed, to remedy the deficiencies in the prior art.
The protection sinking mattress of a kind of submerged pipeline that the present invention relates to, it is made up of module, bridle line, rectangular two the laterally zygomorphic truncated rectangular pyramids that are shaped as of described module are formed by stacking, every row's module is aligned in sequence with the module that is listed as greater than 6 along the long axis direction of module, every row module is aligned in sequence with the module of arranging greater than 4 along the short-axis direction of module, by bridle line module is linked to be a soft fascine mattress.
Described module includes the module housing and the concrete of module upper case, module lower case composition; Be provided with casting gate in the middle of the end face of described module upper case, module upper case spiral-lock and fixes as one on the module lower case, and described concrete casting is in module housing.
The described bridle line that passes module becomes the cross form setting in module housing, and is provided with dozen joint or carries out colligation on the crossover node anyhow at each.
Described module housing and connection cable are made by polypropylene plastics.
The protection sinking mattress manufacture method of a kind of submerged pipeline that the present invention relates to, undertaken by following process step:
1. earlier the module lower case is piled up in the working site by designed mattress sinking specification and spacing;
2. be furnished with bridle line on the module lower case, and all be equipped with the joint button anyhow on the point of intersection in each of bridle line, described bridle line is a polypropylene rope.
3. with module upper case spiral-lock on the lower case of module;
4. the flat board of will casting is placed on the module housing, and the casting gate of discharge port on the flat board and module housing crown center is aligned;
5. the concrete that stirs adds and is contained in the module housing, and smashes the device compacting by shake, and after waiting to harden, the mattress sinking of the submerged pipeline that completes protection can be come into operation.
The protection sinking mattress of submerged pipeline involved in the present invention can be in client's appointed place or client's supply base, or even carries out on the floating marine equipment.When using with the protection sinking mattress gland of submerged pipeline on submerged pipeline, make the protection sinking mattress of submerged pipeline become centipede back of the body shape volt on pipeline.
The protection sinking mattress of submerged pipeline of the present invention, its advantage is:
1. the protection sinking mattress gland by submerged pipeline is on submerged pipeline, can stop mattress sinking gland place seawater current to the washing away of sea bed, and protects the ground of pipeline.
2. the protection sinking mattress gland that passes through submerged pipeline prevents that anchor chain from directly destroying pipeline on submerged pipeline.
Description of drawings:
Fig. 1 is a working state schematic representation of the present invention.
Fig. 2 is a profile schematic representation of the present invention.
Fig. 3 is provided with schematic representation for bridle line of the present invention.
Among the figure: 1 module upper case, 2 module lower cases, 3 modules, 4 casting gates, 5 bridle lines.
