Environmental condition residing for marine structure is sufficiently complex, under the effect of drive marine, and will around works pile foundation Producing local scour, pile foundation buried depth reduces, and the performance such as stake lateral displacement and vertical bearing capacity is severely impacted, and possibility affect base The stability of plinth.
Utility model content
The purpose of this utility model is to overcome drawbacks described above, it is provided that one can effectively reduce current to Seabed sediments Migration, keep stablizing of sea bed around pile foundation, reduce basis scour depth around, it is ensured that the performance of blower foundation, simultaneously The marine structure anti-scouring system that difficulty of construction is low, good in economic efficiency.
In order to solve above-mentioned technical problem, the technical solution adopted in the utility model is:
A kind of marine structure anti-scouring system, including cover layer and ballast, described cover layer is by having permeable hole Flexible material forms, and the tiling of described cover layer is arranged, and described ballast uniformly or is according to certain rules distributed in above cover layer, institute State the density density more than sea water of ballast.
Further, also include works basis and connector, described cover layer offers through hole, described works base Plinth is arranged in described through hole, and described works basis is connected with each other with cover layer by connector.
Further, described cover layer is geotextile.
Further, described cover layer be shaped as triangle, tetragon, fan-shaped or circular.
Further, described ballast is sand pocket, concrete block, lead, stone or the native stone wrapped up by earthwork grid.
Further, described ballast be shaped as strip or bulk.
The beneficial effects of the utility model are: this new technique scheme is formed protection against erosion system by cover layer and ballast System, reasonable in design, simple in construction, cover layer is covered in sea bed surface and by the fixing compacting of ballast, is not affected by current.This System can effectively reduce current and wash away blower foundation, the sea marine structure such as cable, submerged pipeline, and service life is long, and This anti-scouring system greatly reduces installation, maintenance and maintenance cost, reduces the offshore construction activity duration, reduces construction difficulty Degree, increases economic efficiency.

Detailed description of the invention
By describing technology contents of the present utility model, structural feature in detail, being realized purpose and effect, below in conjunction with enforcement Mode also coordinates accompanying drawing to be explained in detail.
The design of this utility model most critical is: structure is made up of cover layer and ballast, and sea bed surface can be made not to be subject to Or affected by current less, greatly reduce offshore set-up and install, overhaul and maintenance cost.
Referring to shown in Fig. 1 to Fig. 2, the marine structure anti-scouring system of the present embodiment, including cover layer 1 and ballast 2, described cover layer 1 is made up of the flexible material with permeable hole, and the tiling of described cover layer 1 is arranged, described ballast 2 uniformly or Being distributed in above cover layer 1 according to certain rules, the density of described ballast 2 is more than the density of sea water.
Further, cover layer 1 is possessed isolation and the material of filtration or fabric forms by one or more, both may be used So that current are by isolating current and Seabed sediments again, such as materials such as geotextiles.
Further, the through hole on cover layer 1 can be determined by an isolation and filtering material, or by multiple isolation and Filtering material is spliced to form.
Further, the global geometric shape of cover layer 1 can be adjusted according to residing region flow field situation and execution conditions Whole, works or its basis meet the flow direction and the back of the body flow to overall shape can be different, can be triangle, tetragon, sector, The shapes such as circle.
Further, ballast 2 can use sand pocket, concrete block, lead, stone, the native stone that wrapped up by earthwork grid Blocks etc. are more than the suitable material of sea water specific gravity.
Further, the shape of ballast 2 can be other shapes such as strip, bulk, continuous distribution, make cover layer 1 with Sea bed surface is the most sturdy, prevents cover layer 1 from tilting or floating.
Further, ballast 2 and cover layer 1 can be to be consolidated, it is also possible to be separated from each other.
Further, if washing away of safeguard structure thing basis 3, cover layer 1 perforate can be packed into works basis 3, Or utilize connector 4 to be connected fixing with basis by cover layer 1.Can be only with connector 4, it is possible to be aided with weight compacting fixing.
Further, connector 4 can be the flexible members such as chain, rope, rope, cast or forge the metal rigidity structure of processing Part and non-metallic member.
Further, connector 4 can be welding or be embedded near mud face, basis, or is arranged on when laying cover layer 1 On works basis 3.
Further, native system is applicable to all kinds marine structure.
Basis in case is offshore wind farm single-pile foundation, it is also possible to be applicable to the conduit of ocean platform or offshore wind farm The basis of the various types such as frame, three feet (multiway) frame, gravity type, high-rise pile cap, negative pressure cylinder, and sea cable J-type pipe, seabed electricity Cable, submerged pipeline, other marine structures such as bumper piles, under water anchor pier, anemometer tower etc..
In anti-scouring system in case, works stake footpath is 6m, maximum long a width of 60m and 50m of cover layer 1, selects long 50m fabric width is the geotextile 11 (having overlap) of 6m, and ballast 2 is bar shaped sandbag, is consolidated with cover layer 1.Sand pocket Diameter 20cm, is spaced 20cm.
One of which work progress of the present utility model is: fixing device is contained in after the installation of basis basis suitable position in advance Put, lay small-sized spud pile at cover layer 1 boundary, location during in order to lay cover layer 1 and fixing.When every section of laying starts And when being connected with pile foundation, utilize installation apparatus the fixing device of cover layer 1 with spud pile or pile foundation to be fixed fixed Position and consolidation, start to lay.While laying, utilization is filled sand equipment and is filled sand for sand pocket, lays while complete sand washing limit, until paving If completing.Being pulled out by spud pile after completing, around basis, jackstone is reinforced.
Refer to shown in Fig. 1 to Fig. 2, embodiment one of the present utility model is:
A kind of marine structure anti-scouring system, including cover layer 1 and ballast 2, described cover layer 1 is by having permeable hole Flexible material composition, described cover layer 1 tiling arrange, described ballast 2 uniformly or is according to certain rules distributed on cover layer 1 Side, the density of described ballast 2, more than the density of sea water, also includes works basis 3 and connector 4, described cover layer 1 is opened Being provided with through hole, described works basis 3 is arranged in described through hole, and described works basis 3 is by connector 4 and cover layer 1 Being connected with each other, described cover layer 1 is geotextile, described cover layer 1 be shaped as tetragon, described ballast 2 is sand pocket, institute That states ballast 2 is shaped as strip.
In sum, the marine structure anti-scouring system that this utility model provides, it is made up of anti-cover layer and ballast Hitting system, reasonable in design, simple in construction, cover layer is covered in sea bed surface and by the fixing compacting of ballast, not by the shadow of current Ring.Native system can effectively reduce current and wash away blower foundation, the sea marine structure such as cable, submerged pipeline, and service life is long, And this anti-scouring system greatly reduces installation, maintenance and maintenance cost, reduces the offshore construction activity duration, reduces construction Difficulty, increases economic efficiency.
