Description
Technical field
Offshore wind power foundation structure is the utility model is related to, particularly a kind of annular subregion machinery-waterpower, which is combined, breaks ground out
Slot device.
Background technology
In recent years, offshore wind farm development situation is good, and China bank has built up multiple marine wind electric fields in succession.Offshore wind farm
With wind field turbulivity it is low, be not take up advantage, these features such as arable land, annual utilization hours height and cause offshore wind farm to be significantly better than land
Upper wind-powered electricity generation.But, the exploitation of offshore wind farm is also faced with huge challenge.Maritime environment is complicated, the coupling such as wind, wave, stream and corrosion
Cooperation is with significantly.Therefore requirement of the exploitation of offshore wind farm to its foundation structure in construction and running is all higher.At present,
China's offshore wind farm is pile foundation or composite pile foundation with more foundation structure, and it designs simple, technology maturation and is easy to
Construction.But, pile foundation cost is higher, and the level of (wind, wave, stream etc.) is larger to deforming under lateral load, under some environment,
Pile foundation and non-optimal base form.With the continuous development of industrial technology, scientific circles find wide shallow formula tubular with industrial quarters
Basis is effective against the relatively larger transverse load of offshore wind turbine in the course of the work, and its is simple in construction, and cost is relatively low, and construction is just
It is prompt.Thus, the research for offshore wind turbine cylindrical foundation is progressively carried out and gradually goed deep into, and cylindrical foundation structure is also progressively at me
Applied among the marine wind electric field construction of the state coastal region in east China.
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 discharge function, 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 joined using waterpower and machinery
Cooperation is broken ground device with the fluting of the annular subregion to be broken ground, and it effectively limits the regional extent of disturbed soil, realized
Zonal control, ensure that the control of levelness, and add sand surfing sand discharge apparatus, quickly have so as to which cylindrical foundation be effectively ensured
Imitate the sinking operation of safety.
Utility model content
The purpose of this utility model is problem be present for above-mentioned, proposes that a kind of annular subregion machinery-waterpower is combined and breaks ground
Grooving apparatus, the device effectively limit the regional extent of disturbed soil, realize zonal control, ensure that the control of levelness
System, and sand surfing sand discharge apparatus has been added, so as to which the fast and effective safe sinking operation of cylindrical foundation be effectively ensured.
The technical solution of the utility model：

Plate thickness 5-10mm, it is highly 0.5-1.2m, sets bar drag-line to be oriented in the concrete edge pars intramuralis that each subregion breaks ground in groove
Groove, it is through at the top of drag-line guide groove at the top of cylindrical foundation, bottom is led to subregion and broken ground groove；Each drag-line guide groove bottom is set
Fixed pulley, and top sets rotary power system；Drag-line, rotary power system of the drag-line from one end are set inside drag-line guide groove
Connect, the fixed pulley of the side is connected by drag-line guide groove, then reconnect the fixed pulley of the other end, then the drawing for passing through this survey
Rope guide groove connects the rotary power system of the side；Drag-line guide groove top sets guide pad respectively so that the bottom of drag-line can
Moved reciprocatingly along soil body plane；Drag-line bottom sets seven brushes that break ground, and material is flexible steel wire material, length 20-30cm；It is broken
Soil brush both sides set non-coring respectively, the function of persistently breaking ground for the brush that broken ground with guarantee；The concrete to be broken ground in each subregion in groove
A piece sand surfing Guan Yuyi root sand discharge pipe is set respectively inside side wall, set up separately on the outside of drag-line guide groove, sand surfing pipe diameter 12-
15cm, sand discharge pipe diameter 12-15cm；Extend cylindrical foundation side wall and connect with sand surfing device in the top of sand surfing pipe and sand discharge pipe
Connect, bottom extends respectively to side wall lower edge, and is broken ground groove UNICOM with subregion；Grooving apparatus is arranged at subregion and broken ground cylinder corresponding to groove
In the wall on shape basis, connection changeover portion at the top of cylindrical foundation side wall.
The principle of breaking ground of the device is as follows：1) when cylindrical foundation 12 sinks, the soil body that each subregion breaks ground in groove 1 with it is outer
Boundary is separate；2) after opening rotary power system 5, drag-line 6 drives the brush 8 that breaks ground to start to do traverse motion so that the soil body
Disturbance produces mobility；3) water body is rushed to subregion and broken ground in groove 1 in sand surfing pipe 11, further enhances the mobility of disturbed soil,
And carry the soil body and rush to sand discharge pipe 12, the soil body is drained into outside cylinder by sand discharge pipe 12 and corresponding sand discharge apparatus immediately, completes to break ground
Work.
The device is applied to the sinking construction on heavy wall armored concrete tubular basis.
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；It is reciprocating in subregion
Drag-line and the brush that breaks ground can rapidly and uniformly disturb the soil body inside subregion, ensure the mobility of the soil body；Sand surfing, sand discharge dress in subregion
Putting quickly can quickly discharge the soil body after disturbance, improve the sinking efficiency of cylindrical foundation；Break ground brush periphery anti-silting sprue can
Effectively avoid breaking ground brushing and silting occurs in the course of the work；Guide pad in drag-line guide groove, which can effectively ensure that, to be drawn when breaking ground work
The travel track of rope, so as to ensure the operating efficiency broken ground；Machinery breaks ground, and can interact between the devices such as device, sand surfing, sand discharge should
With also can use in conjunction, so as to reach the Comprehensive Control of head and flow during sinking control, and then ensure that
The safety and stability of cylindrical foundation in journey.
