Detailed description of the invention
Construction method tidal current energy generating equipment being fixed on the bottom provided according to a first embodiment of the present invention is provided.As shown in Figure 1, in step S11, make outside framework, buoyancy aid is fixed on outside framework, many outer tubes are fixed on outside framework, respectively multiple reduction resistance to water-flow structure is set at the side position that meets water of many outer tubes.
In practical application, make the outside framework be made up of steel on the coast, then in the one-body molded reduction resistance to water-flow in outside framework many places structure.Reducing resistance to water-flow structure in the side that meets water of outer tube by arranging, substantially reducing the lifting surface area that outer tube (just forming stake herein afterwards) bears hydraulic blow, having increased substantially the stability of the stake of follow-up formation simultaneously.In the present embodiment, outer tube is steel pipe, is fixed on outside framework by welding manner.
For in Fig. 4 from left several secondary series four outer tubes, because outer tube has lined up the row being parallel to water (flow) direction, the water flow impact pressure that the outer tube being therefore positioned at downstream bears greatly can reduce after the stop of outer tube being positioned at upstream.Find after experiment, reduce resistance to water-flow structure if do not have, the water flow impact pressure sum that four outer tubes bear is about 2.6 times of being exposed to the water flow impact pressure that the outer tube in water bears.But, after outside framework is provided with reduction resistance to water-flow structure of the present invention, the water flow impact pressure sum that four outer tubes bear be only that is exposed to the water flow impact pressure that the outer tube in water bears 30%.
In the present embodiment, the cross section reducing resistance to water-flow structure is triangle.But the present invention is not limited in any way the concrete shape and structure that reduce resistance to water-flow structure.In other embodiments, this reduction resistance to water-flow structure can be fabricated to streamlined.
In step S12, many inner sleeves are inserted in described many outer tubes accordingly.Specifically, inner sleeve is inserted in outer tube, but can move along the axis of outer tube.A sheathed inner sleeve of outer tube.But the present invention is not limited in any way this.In other embodiment, the quantity of outer tube can more than the quantity of inner sleeve.In this step, inner sleeve in insertion outer tube after, and outer tube is first fixed, the radial and axial movement of restriction inner sleeve.
In step S13, outside framework is inserted in water, in water, pull outside framework to infield.In practical application, because tidal current energy generating equipment will ensure efficient generating, therefore the infield of tidal current energy generating equipment needs to be selected in the larger waters of water velocity, and distance bank, infield has not short distance.
In prior art, be first with ship, whole TRT loading is transported to infield, and then by crane barge ship, TRT hung in water, sink under water.Due to period delivery vehicle and lifting tool bears is the gravity of whole TRT, the therefore scale of the TRT restriction of maximum load that instruments such as being subject to crane barge ship can be born.In addition, tidal current energy generating equipment is fixed on the bottom, as the term suggests TRT will sink, therefore, in prior art, basic nobody is expected in outside framework, increase any thing that can produce buoyancy.But the present invention innovatively arranges buoyancy aid in outside framework, whole TRT first can be suspended in water, then can move horizontally outside framework in water, whole device just can be dragged to infield by the instruments such as steamer easily.
In step S14, after outside framework is transported to infield, one end of every root inner sleeve sinks under water along the axis of outer tube, and the other end stretches out in the water surface.Specifically, because inner sleeve and outer tube fix (such as by modes such as buckles) at the beginning, therefore inner sleeve can not produce relative to outer tube when dragging in water and move.Be dragged to behind infield until outside framework, untie fixing between inner sleeve and outer tube.Now, inner sleeve is inserted toward water-bed direction, until one end of inner sleeve touches the bottom.The length of inner sleeve of the present invention will be longer than the depth of water at infield place, and therefore, the water surface is stretched out in other one end of inner sleeve.
In the present embodiment, step S12, namely inner sleeve is inserted in outer tube is complete on the coast, before being namely positioned at step S13.But the present invention is not limited in any way the order between step S12 and step S13.In other embodiment, can first outside framework be inserted in water, in water, pull outside framework to infield, then by instruments such as crane barge ships, each inner sleeve is sling one by one and inserts in outer tube.Namely step S12 is between step S13 and step S14.No matter be which kind of sequence of steps, all in the scope of protection of present invention.
In step S15, the buoyancy laying down buoyancy aid makes outside framework sink under water, the level of adjustment outside framework.In the present embodiment, buoyancy aid is the buoyancy tank of buoyancy force adjustable, and the step that the buoyancy laying down buoyancy aid makes outside framework sink under water comprises the valve opening buoyancy aid, buoyancy aid is poured water thus lays down buoyancy.But the present invention is not limited in any way this.In other embodiment, buoyancy aid can be the buoyancy tank that can not regulate buoyancy, now, to lay down the buoyancy of buoyancy aid, can direct labor be removed by buoyancy aid.In practical application, judge whether level can be judged by the degree of depth of inner sleeve submerged for the outside framework that sinks to, the level of adjustment outside framework regulates by the mode such as hoist engine or jack.In other words, in the present invention, one of them effect of inner sleeve judges exactly and regulates the level of outside framework.
In step S16, axially hammering is carried out to the bottom along inner sleeve, in inner sleeve, holed in the bottom, form stake holes, take out inner sleeve, towards outer tube built-in enter splicing sleeve, the upper end, ground of the bottom of splicing sleeve outer sleeve for connecting and water-bed boring, towards outer tube built-in enter reinforcing cage or steel tube profile, concrete perfusion in outer tube.In step S17, the hydraulic turbine and generator are installed on outside framework.In practical application, now the hydraulic turbine can be hung in water and install.In the present embodiment, step S17 is positioned at finally.But the present invention is not limited in any way this sequence of steps.In other embodiment, the hydraulic turbine and generator can just be arranged in outside framework on the coast.Then be dragged to infield with outside framework, carry out the bottom afterwards and fix.No matter be which kind of sequence of steps, all in the scope of protection of present invention.
Construction method tidal current energy generating equipment being fixed on the bottom provided according to a second embodiment of the present invention is provided.The top view be fixed on by tidal current energy generating equipment in water-bed construction method implementation process provided according to a second embodiment of the present invention is provided.The top view of the tidal current energy generating equipment provided according to a second embodiment of the present invention is provided.Figure 5 shows that the elevation when tidal current energy generating equipment provided according to a second embodiment of the present invention is not driven piles.Part outside framework after the tidal current energy generating equipment piling provided according to a second embodiment of the present invention and outer tube schematic diagram are provided.Piling schematic flow sheet tidal current energy generating equipment being fixed on water-bed construction method provided according to a second embodiment of the present invention is provided.The structural representation of outer tube and splicing sleeve during the piling provided according to a second embodiment of the present invention.Please also refer to Fig. 2 to Fig. 7.
In the second embodiment, tidal current energy generating equipment 100 being fixed on water-bed F(the present embodiment is seabed) construction method comprise step S21 to S31.Tidal current energy generating equipment 100 comprises outside framework 1, many outer tubes 3, many splicing sleeves 31, buoyancy aid 2, the hydraulic turbine 81 and generators 82.Outside framework 1 has multiple reduction resistance to water-flow structure 4.The type of the present invention to the hydraulic turbine 81 is not limited in any way.
In step S21, make outside framework 1, buoyancy aid 2 is fixed on outside framework 1, many outer tubes 3 are fixed on outside framework 1, respectively multiple reduction resistance to water-flow structure 4 is set at the side position that meets water of many outer tubes 3.As shown in Figure 6, in practical application, the axial A of some outer tube 3 is perpendicular to horizontal plane, and the axis of other outer tubes 3 and horizontal plane out of plumb, be the outer tube 3 of inclination.When whole outside framework 1 is fixed on water-bed F, the outer tube 3 of inclination will be positioned at the upstream and downstream of outside framework 1, thus strengthens the stability that outside framework 1 is positioned at water-bed F.
Reduce resistance to water-flow structure 4 needs and be arranged on the side that meets water being positioned at outermost outer tube 3.Because direction of tide has flood tide and ebb tide, therefore, as shown in Figure 4, the top and bottom that resistance to water-flow structure 4 is positioned at outside framework 1 is reduced.Being positioned at middle outer tube 3, owing to there being the stop of both sides outer tube 3, reducing resistance to water-flow structure 4 without the need to arranging.In the present embodiment, the quantity of outer tube 3 is 20, and reducing resistance to water-flow structure 4 is 16, and the quantity reducing resistance to water-flow structure 4 is less than the quantity of outer tube 3.But the quantity of the present invention to outer tube 3 and reduction resistance to water-flow structure 4 is not limited in any way.In other embodiments, outer tube 3 can only have four, lays respectively at four drift angles of outside framework 1, reduces resistance to water-flow structure 4 and also correspondingly arranges four.
Outside framework 1 comprises at least one platform 11, and the length direction of platform 11 is parallel to water (flow) direction D, and the quantity of outer tube 3 is at least four, and at least four outer tubes 3 are arranged at four drift angles of platform 11 respectively.By arranging platform 11, adding the fixed-area of whole outside framework 1, improve the firmness that outside framework 1 is fixed on water-bed F.In the present embodiment, outside framework 1 comprises two platforms 11.Preferably, the straight line that platform 11 rearranges along the hydraulic turbine is symmetrical arranged.But the present invention is not also limited in any way this.
In the present embodiment, the setting direction of buoyancy aid 2 is parallel to water (flow) direction D, and part outer tube 3 is preferably located between two buoyancy aids 2.By this set, buoyancy aid 2 by outer tube 3 " parcel " wherein, reduces the water flow impact pressure that outer tube 3 bears further.
In step S22, many inner sleeves 5 are inserted in many outer tubes 3 accordingly.The internal diameter of outer tube 3, only slightly larger than the external diameter of inner sleeve 5, can be provided with fixed structure to limit inner sleeve 5 movement radially in outer tube 3.In practical application, first can overlap on the outer wall of inner sleeve 5 and have multiple rubber ring, after inner sleeve 5 inserts outer tube 3, rubber ring had both limited moving radially of inner sleeve 5, form again the sealing ring between inside and outside sleeve pipe, make inside and outside sleeve-shaped integral, jointly stressed.In the second embodiment, after inner sleeve 5 inserts outer tube 3, by modes such as buckles, first limit inner sleeve 5 and move relative to the axial A of outer tube 3.
In the present embodiment, construction method also comprises in step S23, arranges many fixing wireropes 6, and outside framework 1 is fixed in one end of fixing wirerope 6.The sequencing of the present embodiment to step S23 and step S22 is not limited in any way.In step S24, outside framework 1 is inserted in water, in water, pull outside framework 1 to infield.After step S24, in step S25, fixed by the other end of fixing wirerope 6, the wirerope 6 that is strained and fixed is parallel to the lateral attitude of horizontal plane with fixing outside framework 1.Specifically, be provided with multiple fixed tower 61 on the coast with in water, the two ends of fixing wirerope 6 are individually fixed in fixed tower 61 and outside framework 1.
In step S26, regulated the level of outside framework 1 by buoyancy aid.After tentatively securing the horizontal level of outside framework 1 by fixing wirerope 6, next utilize level gauge, detect the level of outside framework 1.If outside framework 1 is out-of-level, then by regulating the buoyancy of both sides buoyancy aid 2 to carry out Level tune.When buoyancy aid 2 is buoyancy tanks of buoyancy force adjustable, can directly regulates the water level in buoyancy tank to change buoyancy by pouring into water, thus reach the object of adjustment level.When buoyancy aid 2 is the buoyancy tanks with fixed buoyancy, by increasing or remove buoyancy tank to realize in water horizontal adjustment to outside framework 1.
In step S27, after having adjusted the level of outside framework 1, to be sunk under water F along the axial A of outer tube 3 one end of every root inner sleeve 5, the other end stretches out in the water surface.In step S28, the buoyancy laying down buoyancy aid 2 makes outside framework 1 sink under water the level of F, adjustment outside framework 1.Adopt fixing wirerope 6 because the present embodiment has, so now first loosen fixing wirerope 6, then whole outside framework 1 is sunk.
In the present embodiment, the outer wall mark of inner sleeve 5 has scale (not shown).Therefore, by the scale change numerical value outside reading inner sleeve 5, i.e. the level of the known depth of water everywhere rear outside framework 1 and judgement is sunk.After discovery outside framework 1 is out-of-level, the level of adjustment outside framework 1.Specifically, in the present embodiment, one end of inner sleeve 5 is fixed by hoist engine 9 and outside framework 1.When the outside framework 1 of side is on the low side, now can drive hoist engine 9, make the outside framework 1 that it lifts this side, after read the special value arriving inner sleeve 5 on the water surface, namely represent outside framework 1 level, now stop the continuation of hoist engine 9 to regulate.But the mode of the present invention to the level of adjustment outside framework 1 is not limited in any way.In other embodiment, realize the Level tune of outside framework 1 by arranging jack.By the outer wall mark scale at inner sleeve 5, constructor can intuitively and the whole outside framework 1 that forms a prompt judgement comprises platform 11 whether level, thus instruct and further construct.But the present invention is not limited in any way this.When there is no scale outside inner sleeve 5, still judge the level of outside framework 1 by the degree of depth of actual measurement inner sleeve 5 submerged.The inner sleeve 5 of the present embodiment can play adjustment horizontal force.
In step S29, axially hammering is carried out to water-bed F along inner sleeve, in inner sleeve 5, water-bed F is holed, form stake holes 33, take out inner sleeve 5, in outer tube 3, insert splicing sleeve 31, the bottom of splicing sleeve 31 outer sleeve for connecting 3 and the upper end, ground of water-bed boring, reinforcing cage 32 or steel tube profile is inserted, concrete perfusion in outer tube 3 in outer tube 3.Preferably, before concrete perfusion, reinforcing cage 32 and steel tube profile all put into outer tube 3, and steel tube profile can be split obtained by inner sleeve 5, so both saves raw material, make again the stake formed be steel pipe pile, increase the uplift resistance of whole stake.
As shown in Figure 7, because water-bed F is uneven, inner sleeve 5 is after submerged, and the bottom of inner sleeve 5 all can not contact with water-bed F.First beat to stretch in inner sleeve 5 with stake and carry out hammering to water-bed F, after beating out hole, by inner sleeve 5 toward pressing down, under making the bottom of inner sleeve 5 be embedded into water-bed F a little.Now, except open top, in inner sleeve 5, define a substantially airtight space, so complete before spudding in and prepare.Then stretched into by auger in inner sleeve 5, the horizon d vertically towards water-bed F is holed, and gets into the degree of depth meeting construction requirement always, forms stake holes 33.In practical application, the degree of depth of stake holes 33, at about 6m, so just can make pile foundation be embedded into horizon d, makes the stake of formation more firm.Take out inner sleeve 5 subsequently, inserted by splicing sleeve 31 in outer tube 3, the bottom of splicing sleeve 31 outer sleeve for connecting 3 and the upper end, ground of water-bed boring, form airtight space again.Then in outer tube 3, put into reinforcing cage 32 or steel tube profile, concrete perfusion in outer tube 3, form deposited reinforced concrete pile.
Due to water-bed uneven, outside framework 1 sinks under water after F, and the bottom of outer tube 3 also can not all touch water-bed F certainly.Therefore, if there is no inner sleeve 5, cannot confined space be formed, and stop current and the stone of outside, also just cannot realize boring.Meanwhile, the earth got out and stone, by being sucked away in inner sleeve 5, are discharged from inner sleeve 5 upper end open.After inner sleeve 5 is extracted, splicing sleeve 31 being set when driving piles, still ensureing to form confined space under water, preventing concrete from leaking, cast-in-place concrete pile is formed.If do not pull out away inner sleeve 5 when forming stake, directly concrete perfusion in inner sleeve 5, owing to there is gap between inner sleeve 5 and outer tube 3, then can cause between outer tube 3 and concrete pile and there is gap, make the two effectively not be fixed together, finally cause outside framework 1 meeting opposite concrete stake slide downward.
In the present embodiment, the construction method that tidal current energy generating equipment 100 is fixed on water-bed F is also comprised step S30.In step S30, in outer tube 3 after concrete perfusion, fixed head 34 is set on concrete top, fixed head 34 is welded mutually with outer tube 3.In practical application, fixed head 34 is circular steel plate, is welded on the inwall of outer tube 3, is placed in the top of concrete pile.Due to the weight very heavy (up to more than 3000 tons) of outside framework 1, but outer tube 3 is round steel cylinder, and frictional force between concrete pile is less, after Long-Time Service, outer tube 3 can slide in opposite concrete stake, causes outside framework 1 constantly to sink, even produce inclination, affect generating efficiency.By arranging fixed head 34, further outside framework 1 and concrete pile are fixed together, if outside framework 1 will sink, then can stop by stake, thus keep the permanent position of whole outside framework 1.Preferably, above fixed head 34, go back extension supporting pin 35 to be connected and fixed plate 34 and outer tube 3 further.
