Description
Technical field
Offshore wind power foundation structure is the utility model is related to, particularly a kind of annular subregion waterpower is broken ground grooving apparatus.
Background technology
Offshore wind farm has the advantages such as wind field fluidised form is good, be not take up soil, annual utilization hours height, development situation in recent years
It is very good.However, maritime environment is complicated, the requirement to foundation structure is general higher.At present, the basis knot being most widely used
Structure surely belongs to pilework or spreading out for pilework stretches structure.But, the cost of pile foundation is higher, and economy is not good.Simultaneously as
The lateral load of blower fan is larger, easily causes pile foundation that larger transversely deforming occurs.As engineering circles and academia are to sea
The continuous exploration of works and research, it has been found that wide shallow formula cylindrical foundation is effective against offshore wind turbine in the course of the work
Relatively larger transverse load.Thus, the research for offshore wind turbine cylindrical foundation is progressively carried out and gradually goed deep into, and cylindrical foundation structure
Also progressively applied among the marine wind electric field construction in Deposits in Eastern Coastal China area.
At this stage, cylindrical foundation uses thin-wall steel pipe structure more, and this is simple and light, easily fabricated, is also easy to negative pressure
Sink.But, for some geological conditions, the sinking operation of cylindrical foundation needs to apply very big negative pressure, and excessive negative pressure
The bending deformation of barrel can be caused, the final safety and stability for influenceing structure.Therefore, some scholars suggest the cylinder using steel and concrete structure
Shape basis.But steel reinforced concrete cylindrical foundation is thick-walled structure, the end resistance of sinking watching is very big, it is impossible to ensures fast and effectively to sink to making
Industry.Broken ground device therefore, scholars further propose to set in steel reinforced concrete cylindrical foundation bottom, as fluting breaks ground or high pressure spray
Penetrate and break ground.However, the current device that breaks ground all is overall structure, integrally break ground.Once the geology of the different parts of cylindrical foundation
Structure has differences, it is easy to causes the levelness in cylindrical foundation sinking watching unbalance.In addition, there is not one kind to break ground at present
Device has sand surfing or sand flushing system, and after soil disturbance, the soil body of disturbance still has cylindrical foundation bottom so that basic
Sinking is inefficient, and the risk for expanding soil disturbance region be present.Therefore, the application proposes that one kind is carried out using hydraulic action
The fluting of the annular subregion to break ground breaks ground device, and it effectively limits the regional extent of disturbed soil, realizes zonal control, protects
The control of levelness has been demonstrate,proved, and has added sand surfing sand discharge apparatus, cylindrical foundation is fast and effective safe to sink so as to be effectively ensured
Put operation.
Utility model content
The purpose of this utility model is problem be present for above-mentioned, proposes that a kind of annular subregion waterpower is broken ground grooving apparatus,
The device effectively limits the regional extent of disturbed soil, realizes zonal control, ensure that the control of levelness, and adds
Sand surfing sand discharge apparatus, so as to which the fast and effective safe sinking operation of cylindrical foundation be effectively ensured, effectively increase effect of breaking ground.
The technical solution of the utility model：
A kind of annular subregion waterpower is broken ground grooving apparatus, is broken ground groove, subregion dividing plate, high pressure spray flow tube, high pressure spray by subregion

Plate is separated into 6-10 subregion and broken ground groove；Subregion breaks ground groove as two circle steel plate structures, steel plate thickness 5-10mm, is highly 0.5-
1.2m, two high pressure spray flow tubes, two sand surfing Guan Yuyi roots rows are buried in the concrete edge pars intramuralis that each subregion breaks ground in groove
Sandpipe, sand discharge pipe, high pressure spray flow tube and sand surfing pipe are sequentially arranged from centre to both sides；High-pressure jet pipe diameter 12-15cm, high pressure
Extend cylindrical foundation side wall at the top of jet pipe and be connected with high-pressure jet device, bottom extends to side wall lower edge, then occurs
90 ° of knuckles so that duct orientation is perpendicular to side wall and parallel to bottom surface；In high pressure spray flow tube transverse end head, high pressure spray flow tube is set
Plug, water body continues to move ahead in blocking tube；5-10, diameter are set in the bottom of the high pressure spray flow tube pipeline section parallel to bottom surface
0.8-1.5cm high-pressure nozzle, shower nozzle periphery set anti-silting sprue；Cylinder is extended in sand surfing pipe diameter 12-15cm, sand surfing tube top portion
Shape basis side wall is simultaneously connected with sand surfing device, and bottom extends to side wall lower edge, and is broken ground groove UNICOM with subregion；Sand discharge pipe diameter
15cm, sand discharge tube top portion extend cylindrical foundation side wall and are connected with sand discharge apparatus, and bottom extends to side wall lower edge, and and subregion
Break ground groove UNICOM；Grooving apparatus be arranged at subregion break ground cylindrical foundation corresponding to groove wall in, connect at the top of cylindrical foundation side wall
Changeover portion.
The principle of breaking ground of the device is：1) when cylindrical foundation 9 sinks, the soil body and the external world that each subregion breaks ground in groove 1
Independently of each other；2) high-pressure water body flow to the side wall bottom of cylindrical foundation 9 by high pressure spray flow tube 3, and by high-pressure nozzle 5 spray and
Go out, immediately high-pressure jet disturbed soil so that the soil body is produced compared with large fluidity；3) water body is rushed to subregion and broken ground groove 1 in sand surfing pipe 7
It is interior, the mobility of disturbed soil is further enhanced, and carry the soil body and rush to sand discharge pipe 8, the soil body passes through sand discharge pipe 8 and phase immediately
Answer sand discharge apparatus to drain into outside cylinder, complete work of breaking ground.
The grooving apparatus is applied to heavy wall armored concrete tubular basis sinking construction.
The beneficial effects of the utility model are：
The grooving apparatus realizes that each section is broken ground work by setting annular subregion effectively to reduce the disturbance region of the soil body
The independent progress of work, so as to effectively lift the levelness control ability in cylindrical foundation sinking watching；High speed jet in subregion
Fluidic system can the soil body inside rapid perturbations subregion, ensure the mobility of the soil body, overcome Underwater Pressure；Sand surfing, row in subregion
Husky device quickly can quickly discharge the soil body after disturbance, improve the sinking efficiency of cylindrical foundation；Anti-silting sprue around shower nozzle
Effectively it can avoid shower nozzle that silting occurs in the course of the work；Can interactive application between the devices such as jet flow, jet, sand surfing, sand discharge
Can use in conjunction, so as to reach the Comprehensive Control of head and flow during sinking control, and then ensure that in sinking watching
The safety and stability of cylindrical foundation.
