Description
Technical field
The present invention relates to offshore wind power foundation structure, particularly a kind of annular subregion waterpower is broken ground grooving apparatus.
Background technology
Offshore wind farm has the advantages, development situation in recent years such as wind field fluidised form is good, be not take up soil, annual utilization hours is high
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 that pile foundation occurs larger transversely deforming.As engineering circles and academia are to sea
The continuous exploration of works and research, it has been found that shallow formula cylindrical foundation wide 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 is gradually goed deep into, and cylindrical foundation structure
Also progressively applied in the middle of the marine wind electric field construction in Deposits in Eastern Coastal China area.
At this stage, thin-wall steel pipe structure is used cylindrical foundation, this is simple and light, it is easy to manufacture, and is also easy to negative pressure more
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 safety and stability of final influence structure.Therefore, cylinder of some scholars suggestion 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 ensure fast and effectively to sink to making
Industry.Therefore, scholars further propose sets the device that breaks ground in steel reinforced concrete cylindrical foundation bottom, such 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 cause the levelness in cylindrical foundation sinking watching unbalance.In addition, not thering is 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 basis
Sinking is inefficient, and there is the risk for expanding soil disturbance region.Therefore, the application proposes that one kind is carried out using hydraulic action
The fluting of the annular subregion for breaking ground breaks ground device, and its regional extent for effectively limiting disturbed soil realizes zonal control, protects
The control of levelness is demonstrate,proved, and has added sand surfing sand discharge apparatus, so as to the heavy of the quick effective and safe of cylindrical foundation has been effectively ensured
Put operation.
The content of the invention
The purpose of the present invention be directed to it is above-mentioned there is problem, propose that a kind of annular subregion waterpower is broken ground grooving apparatus, the dress
The regional extent for limiting disturbed soil is set effective, zonal control is realized, it is ensured that the control of levelness, and added sand surfing
Sand discharge apparatus, so as to the sinking operation of the quick effective and safe of cylindrical foundation has been effectively ensured, effectively increase effect of breaking ground.
Technical scheme：
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
Flow tube plug, high-pressure nozzle, anti-silting sprue, sand surfing pipe, sand discharge pipe constitute, cylindrical foundation side wall bottom by 6-10 blocks subregion every
Plate is separated into 6-10 subregion and breaks ground groove；Subregion breaks ground groove for two enclose steel plate structures, and steel plate thickness 5-10mm is highly 0.5-
1.2m, in the embedded two high pressure spray flow tubes of concrete edge pars intramuralis, two sand surfing Guan Yuyi roots rows that each subregion breaks ground in groove
Sandpipe, sand discharge pipe, high pressure spray flow tube and sand surfing pipe are sequentially arranged to both sides from centre；High-pressure jet pipe diameter 12-15cm, high pressure
Jet pipe top is extended cylindrical foundation side wall and is connected with high-pressure jet device, and 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；In the bottom of the high pressure spray flow tube pipeline section parallel to bottom surface, 5-10, diameter are set
The high-pressure nozzle of 0.8-1.5cm, shower nozzle periphery sets anti-silting sprue；Extend cylinder in sand surfing pipe diameter 12-15cm, sand surfing pipe top
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 pipe top is extended cylindrical foundation side wall and is 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 the corresponding cylindrical foundation of groove wall in, cylindrical foundation side wall top connection
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
It is separate；2) high-pressure water body flow to the side wall bottom of cylindrical foundation 9 by high pressure spray flow tube 3, and sprayed by high-pressure nozzle 5 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 carries the soil body and rushed 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 are applied to heavy wall armored concrete tubular basis sinking construction.
The beneficial effects of the invention are as follows：
The grooving apparatus can effectively reduce the disturbance region of the soil body by setting annular subregion, realize that each interval is broken ground work
Work is independently carried out, so that the levelness control ability effectively in lifting cylindrical foundation sinking watching；High speed jet in subregion
Fluidic system can rapid perturbations subregion inside the soil body, it is ensured that 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
Shower nozzle can be prevented effectively from 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 sinking watching
The safety and stability of cylindrical foundation.
