Water side is also increased considerably, that is, increased lifting surface area of each pile by water flow impact pressure.Due to water side increase,
Reduce on the contrary and even counteract the firmness that overstriking stake brings, and difficulty of construction is also greatly increased.Therefore, it is existing to be fixed on
It is fixed not firm that water-bed tidal current energy generating equipment is all present, the problem that construction is complicated, dangerous, cost is too high.
In addition, existing tidal current energy generating equipment is typically for its framework to be hung in installation ground by instruments such as crane barge ships
The bottom of point.Because tidal current energy generating equipment needs long period of soaking in water and to bear the impact of current, in order to increase tide
In water-bed stable degree, its framework is most of to be made stream energy TRT of reinforcing bar and concrete, and usual whole device can build

Specific embodiment
Fig. 1 show the construction party that tidal current energy generating equipment is fixed on the bottom for providing according to a first embodiment of the present invention
Method.As shown in figure 1, in step S11, making outer framework, floating body is fixed on outer framework, many outer tubes are fixed on housing
Frame, respectively in many multiple reduction resistance to water-flow structures of side position setting that meet water of outer tubes.
In practical application, the outer framework being made up of steel is made on the coast, be then integrally formed in outer framework many places and subtracted
Weep resistance structure.Reduce resistance to water-flow structure in the side that meets water of outer tube by setting, substantially reduce outer tube（Afterwards
Stake is just being formed herein）The lifting surface area of hydraulic blow is born, while the stability of the stake being subsequently formed is greatly improved.In
In the present embodiment, outer tube is steel pipe, is fixed on outer framework by welding manner.
As a example by Fig. 4 from four outer tubes of left several secondary series, because outer tube has lined up parallel to water (flow) direction
Row, the water flow impact pressure born therefore in the outer tube in downstream can be greatly reduced after the stop positioned at the outer tube of upstream.
By being found after experiment, if without resistance to water-flow structure is reduced, the water flow impact pressure sum that four outer tubes bear is one
2.6 times or so of the water flow impact pressure that the outer tube being exposed in water bears.However, being provided with of the invention subtracting on outer framework
After weep resistance structure, the water flow impact pressure sum that four outer tubes bear is only that an outer tube being exposed in water bears
Water flow impact pressure 30%.
In the present embodiment, the section for reducing resistance to water-flow structure is triangle.However, the present invention is to reducing resistance to water-flow
The concrete shape and structure of structure are not limited in any way.In other embodiment, the reduction resistance to water-flow structure can be fabricated to stream
Line style.

The larger waters of degree, infield has not short distance apart from bank.
In in the prior art, being that whole TRT first is loaded into transport to infield with ship, crane barge is then passed through again
Ship hangs in TRT in water, sinks under water.What is born due to period delivery vehicle and lifting tool is whole TRT
Gravity, therefore TRT scale restricting the peak load for being subject to the instrument such as crane barge ship to bear.In addition, by tide
Stream energy TRT is fixed on the bottom, as the term suggests, TRT will sink, therefore, it is basic not any in the prior art
People expects increasing in outer framework any thing that can produce buoyancy.However, the present invention innovatively sets floating body in outer framework,
Whole TRT is first suspended in water, the instruments such as outer framework, steamer then can be moved horizontally in water easily just
Whole device can be dragged to infield.
In step S14, after outer framework is transported to infield, every one end of inner sleeve is sunk to along the axial direction of outer tube
The bottom, the other end stretches out in the water surface.Specifically, because inner sleeve at the beginning is mutually fixed with outer tube（For example by buckle etc.
Mode）, therefore inner sleeve will not produce movement when dragged in water relative to outer tube.Treat that outer framework is dragged to installation ground
After point, the fixation between inner sleeve and outer tube is untied.Now, by inner sleeve toward bottom direction insertion, until the one of inner sleeve
End touches the bottom.The length of inner sleeve of the present invention will be longer than the depth of water at infield, therefore, the other end of inner sleeve is stretched
Go out the water surface.
In the present embodiment, it is to complete on the coast that step S12, i.e. inner sleeve are inserted in outer tube, i.e., positioned at step S13
Before.However, the present invention is not limited in any way to the order between step S12 and step S13.In other embodiments, can be first
Outer framework is inserted in water, outer framework is pulled in water to infield, then by instruments such as crane barge ships, by each inner sleeve
Sling one by one and insert in outer tube.That is step S12 is located between step S13 and step S14.Either which kind of sequence of steps,
All in the scope of protection of present invention.
In step S15, laying down the buoyancy of floating body makes outer framework sink under water, and adjusts the level of outer framework.In this implementation
In example, floating body is the buoyancy tank of buoyancy force adjustable, to lay down include the step of the buoyancy of floating body makes outer framework sink under water and opens floating body
Valve, floating body is poured water so as to lay down buoyancy.However, the present invention is not limited in any way to this.In other embodiments, floating body
Can be that can not adjust the buoyancy tank of buoyancy, now, the buoyancy to lay down floating body, can direct labor floating body is removed.Should in reality
In, whether level can be judged the outer framework that judgement is sunk to by the depth of inner sleeve submerged, adjust the level of outer framework
Can be adjusted by modes such as hoist engine or jack.In other words, one of effect of inner sleeve is exactly to sentence in the present invention
Break and adjust the level of outer framework.
In step S16, axially the bottom is hammered along inner sleeve, the bottom is drilled in inner sleeve, formed
Stake holes, takes out inner sleeve, and the ground of connection sleeve pipe, the bottom of connection sleeve pipe outer sleeve for connecting and water-bed drilling is built into towards outer tube
Face upper end, steel reinforcement cage or steel tube profile are built into towards outer tube, towards outer tube in concrete perfusion.In step S17, by water
Turbine and generator are installed on outer framework.In practical application, installed in now the hydraulic turbine being hung in into water.In this implementation
In example, step S17 is to be located at finally.However, the present invention is not limited in any way to this sequence of steps.In other embodiments, water
Turbine and generator just can be arranged in outer framework on the coast.Then infield is dragged to outer framework, water-filling is entered afterwards
Bottom is fixed.Either which kind of sequence of steps, all in the scope of protection of present invention.

In, the axial A of some outer tubes 3 perpendicular to horizontal plane, as incline by axial direction and the horizontal plane out of plumb of other outer tubes 3
Oblique outer tube 3.When whole outer framework 1 is fixed on water-bed F, inclined outer tube 3 will be located at the upstream of outer framework 1 with
Trip, so as to increase stability of the outer framework 1 positioned at bottom F.
Reduce the side that meets water that resistance to water-flow structure 4 only needs to be arranged in outermost outer tube 3.Due to trend
There are flood tide and ebb tide in direction, therefore, as shown in figure 4, reduction resistance to water-flow structure 4 is positioned at the top of outer framework 1 and bottom.
Positioned at middle outer tube 3, due to the stop for having both sides outer tube 3, resistance to water-flow structure 4 is reduced without setting.In this implementation
In example, the quantity of outer tube 3 is 20, and it is 16 to reduce resistance to water-flow structure 4, reduces the quantity of resistance to water-flow structure 4
Less than the quantity of outer tube 3.However, the present invention is not limited in any way to the quantity of outer tube 3 and reduction resistance to water-flow structure 4.
In other embodiment, outer tube 3 can only have four, respectively positioned at four drift angles of outer framework 1, reduce resistance to water-flow structure 4
Also four are correspondingly set.
Outer framework 1 includes at least one platform 11, and the length direction of platform 11 is parallel to water (flow) direction D, the number of outer tube 3
It is at least four to measure, and at least four outer tubes 3 are respectively arranged at four drift angles of platform 11.By setting platform 11, increased
The fixed-area of whole outer framework 1, improves the firmness that outer framework 1 is fixed on water-bed F.In the present embodiment, outer framework 1 is wrapped

In step S22, many inner sleeves 5 are inserted correspondingly into many outer tubes 3.The internal diameter of outer tube 3 is only bigger
Can be provided with fixed structure to limit the movement radially of inner sleeve 5 in the external diameter of inner sleeve 5, outer tube 3.In practical application
In, multiple rubber rings can be first cased with the outer wall of inner sleeve 5, inner sleeve 5 is inserted after outer tube 3, and rubber ring had both limited interior
Moving radially for sleeve pipe 5, forms the sealing ring between inside and outside sleeve pipe so that inside and outside sleeve is integral, common stress again.In
In second embodiment, after the insertion outer tube 3 of inner sleeve 5, by modes such as buckles, axle of the inner sleeve 5 with respect to outer tube 3 is first limited
Moved to A.
In the present embodiment, construction method is also included in step S23, sets many fixed wireropes 6, the one of fixed wirerope 6
Outer framework 1 is fixed at end.The present embodiment is not limited in any way to the sequencing of step S23 and step S22.In step S24,
Outer framework 1 is inserted in water, outer framework 1 to infield is pulled in water.After step S24, in step S25, will be solid
The other end for determining wirerope 6 is fixed, and is strained and fixed wirerope 6 to fix lateral attitude of the outer framework 1 parallel to horizontal plane.It is specific and
Speech, is provided with multiple fixed towers 61 with water on the coast, and the two ends of fixed wirerope 6 are individually fixed in fixed tower 61 and outer framework 1.
In step S26, the level of outer framework 1 is adjusted by floating body.When tentatively securing outer framework by fixed wirerope 6
After 1 horizontal level, next using level meter, the horizontality of outer framework 1 is detected.If the not level of outer framework 1, by adjusting
The buoyancy for saving both sides floating body 2 carries out Level tune.When floating body 2 is the buoyancy tank of buoyancy force adjustable, can directly by pour into water come
The water level in buoyancy tank is adjusted to change buoyancy, so as to reach the purpose of adjustment level.When floating body 2 is the buoyancy tank with fixed buoyancy
When, the horizontal adjustment in water can be realized to outer framework 1 by increasing or removing buoyancy tank.
In step S27, after having adjusted the level of outer framework 1, by every one end of inner sleeve 5 along outer tube 3 axial A
Sink under water F, and the other end stretches out in the water surface.In step S28, laying down the buoyancy of floating body 2 makes outer framework 1 sink under water F, adjustment
The level of outer framework 1.Because the present embodiment has using fixed wirerope 6, so now first loosen fixed wirerope 6, then will be whole
Outer framework 1 sinks.
In the present embodiment, the outer wall of inner sleeve 5 is identified with scale（It is not shown）.Therefore, by reading the outside of inner sleeve 5
Scale change numerical value, you can know the depth of water everywhere and judge sink after outer framework 1 horizontality.When finding the not water of outer framework 1
After flat, the level of outer framework 1 is adjusted.Specifically, in the present embodiment, one end of inner sleeve 5 passes through hoist engine 9 and outer framework
1 mutually fixes.When the outer framework 1 of side is relatively low, can now drive hoist engine 9, it is lifted the outer framework of this side 1, when
Read on the water surface up to after the special value of inner sleeve 5, that is, represent the level of outer framework 1, the continuation for now stopping hoist engine 9 is adjusted

It is limited in any way.When there is no scale outside inner sleeve 5, still can judge outer by the depth of the actual measurement submerged of inner sleeve 5
The horizontality of framework 1.The inner sleeve 5 of the present embodiment can play regulation horizontal force.
In step S29, axially water-bed F is hammered along inner sleeve, water-bed F is drilled in inner sleeve 5, shape
Into stake holes 33, take out inner sleeve 5, connection sleeve pipe 31 be built into towards outer tube 3, the bottom of the outer sleeve for connecting 3 of connection sleeve pipe 31 and
The bottom drilling ground upper end, be built into steel reinforcement cage 32 or steel tube profile towards outer tube 3, towards outer tube 3 in concrete perfusion.
Preferably, before concrete perfusion, steel reinforcement cage 32 and steel tube profile are all put into outer tube 3, and steel tube profile can be by inner sleeve 5
Segmentation is obtained, and so both saves raw material, causes that the stake for being formed is steel-pipe pile again, increases the withdrawal resistance of whole stake.
As shown in fig. 7, because water-bed F is uneven, inner sleeve 5 after submerged, the bottom of inner sleeve 5 can not and water
Bottom F is all contacted.Beaten to stretch into stake first and hammered to water-bed F in inner sleeve 5, after beating out hole, inner sleeve 5 pressed down,
The bottom of inner sleeve 5 is set to be slightly embedded under water-bed F.Now, in addition to open top, one is formd in inner sleeve 5 substantially
Closed space, so completes to prepare before spudding in.Then drilling machine is stretched into inner sleeve 5, axially towards the horizon d of water-bed F
Drilled, the depth for meeting construction requirement is got into always, formed stake holes 33.In practical application, the depth of stake holes 33 is in 6m
Left and right, so can just make pile foundation be embedded into horizon d so that the stake of formation is more consolidated.Inner sleeve 5 is then taken out, by adapter sleeve
Pipe 31 is built into from outer tube 3, the ground upper end of the bottom of the outer sleeve for connecting 3 of connection sleeve pipe 31 and water-bed drilling, again shape
Into closed space.Then steel reinforcement cage 32 or steel tube profile are put into the outer tube 3, towards outer tube 3 in concrete perfusion, shape
Into deposited reinforced concrete pile.
Because water-bed injustice, outer framework 1 sink under water after F, the bottom of outer tube 3 also will not all touch the bottom certainly
F.Therefore, if without inner sleeve 5, will be unable to form confined space, current and stone outside stop also cannot just be realized boring
Hole.Meanwhile, the soil and stone for getting out are discharged by being sucked away in inner sleeve 5 from the upper end open of inner sleeve 5.Inner sleeve 5 is extracted
Afterwards, connection sleeve pipe 31 is set in piling, still ensures that and form confined space under water, prevent concrete from leaking so that coagulation
Native bored concrete pile is formed.If inner sleeve 5 is not pulled out away when stake is formed, directly the concrete perfusion in inner sleeve 5, due to interior
There is gap between sleeve pipe 5 and outer tube 3, then can cause there is gap between outer tube 3 and concrete-pile, prevent the two from having
Effect it is fixed together, ultimately causing outer framework 1 can opposite concrete stake slide downward.
