Description

Automatic sluice gate with buoyancy programmed control

The invention belongs to the water conservancy and hydropower technical field.It belongs to roof weir gate in the classification of hydraulic gate.

It is investigated card, original roof weir gate is to be invented in 1818 by American White (Jasiah White), when beginning to build, has made up a story in order to confuse the masses, advocation is to build the large-scale trap of catching black bear, and must be called bear well gate (Bear-trap gate).Bear well gate is successively built in ten engineerings in the development of the U.S., lasts 88 years, and maximum port size reaches 48.6 * 5m.U.S. engineer Parker (Parker) is in " control of water " (The Contral of water) of works in 1916 book, describe bear well gate in detail in engineering practice, generally occur from floating, self-locking and phenomenon such as asynchronous, and cause destruction, and point out: " failure of this gate has two big reasons: (1) design is bad; the flashboard ratio is improper, easily self-locking when landing; (2), take place serious asynchronous in when landing because lateral stiffness is not enough." after this book publishes, engineering circle of the U.S. just nobody adopt this gate again.

Afterwards, this technology was imported Europe into, became roof weir gate about nineteen thirty by the Hu Bai of Swede (Huber) design improvement.We can say to have the gate of sector-like shape and the drum gate of bleeding edge in modern age, also is on the engineering practice basis of summing up various roof weir gates, and innovation improves and forms.

First bear-trap dam of China is built in September nineteen sixty-eight, and promptly Henan Province faces Huanglong's canal bear-trap dam (8 * 2m) that clever county water conservancy bureau builds.Subsequently this county water conservancy bureau again in July, 1970 build up the Da Guo bear-trap dam (26.5 * 4.5m), put on display in Guangzhou trade fair in autumn in 1971 as the technological innovation achievement, and then in all parts of the country in short several years, successively build up about 23 bear-trap dam engineerings.Hydraulic and electric engineering publishing house has published " bear-trap dam " book in January, 1973 for this reason, and bear-trap dam is used widely throughout the country, and about 50 of bear-trap dam engineering has been built in the whole nation so far.But engineering practice proves, the bear-trap dam built of initial stage all exists serious self-locking, phenomenon such as floating certainly, out of control and asynchronous, and exposes that maintenance is difficult, the life-span is short, water shutoff is poor, operates serious problems such as the bad and flashboard structure destruction of runnability.Afterwards, through the verification document, the bear-trap dam of just finding China was in construction profile, and operation characteristic is upward very similar to the bear well gate of the U.S. with existing problems, and the someone advocates for this reason, and the bear-trap dam of China will have same end with the bear well gate of the U.S..

The inventor has accepted Luoyang City's Gold Water River reservoir spillway bear-trap dam (design objective of 26 * 6m) in 1972, grind the serious problems that expose in the examination at bear-trap dam engineering practice and model, in conjunction with the gains in depth of comprehension of being engaged in the design of hydraulic gate and metal construction, manufacturing, installation for a long time, carry out ten innovations audaciously and improve---set up the hinged inching gear of steel work intermediate chain bar and enhancing integral rigidity; Improve flashboard structure design conditions and gallery valve system; Improve water shutoff connection, construction hoisting and maintenance support etc.This bear-trap dam was completed in August, 1974, just stood once the intense impact check of unexpected " flood breaks down " immediately, and bear-trap dam rises the lock dash apace, lifting nimbly and freely, without any floating certainly, self-locking, out of control and asynchrony phenomenon.After particularly " 75.8 " extraodinary flood disaster appears in Henan Province, the operation performance of high water level is carried out in the managerial decision of Henan Province water conservancy department at this lock, allow the various places, city, the county water conservancy chief that participate in a conference all visit, so that widely popularize on each reservoir spillway.Carried out the high water level operation demonstration on October 17th, 1975, its good runnability of operation is reliably inspired leader's favor at different levels of visit as a result.Thereafter a collection of reservoir spillway has been built bear-trap dam in succession.Grinding of Luoyang Gold Water River reservoir spillway bear-trap dam tries and the design improvement success, indicates the birth of second generation bear-trap dam.So far move more than 20 year, stable and reliable for performance, not overhaul as yet.

It is worth mentioning August 3 nineteen eighty-two, Huixian, Henan Province Shimen Dam flood spillway bear-trap dam (accident destruction of 47 * 6.25-7m), unexpectedly done once most valuable " destructive testing " for design, construction and the operational administrative of second generation bear-trap dam, for the development of bear-trap dam provides the most convictive scientific basis.Because the survey report of the scene of the accident, photo and party's dictated material proves: every principle, principle and the calculation assumption of the design of second generation bear-trap dam are safe and reliable; Every by the various steel work component of design drawing requirement manufacturing and the reinforced concrete member of normal construction, all stand the current special doubly load " destructive testing " and not destruction of surpassing; This bear-trap dam has 18 flashboard unit, be coupled to " semi-rigid " overall structure with powerful " hinged inching gear " and the water shutoff of epoxy resin mortar seam, the result has only destroyed 10 flashboard unit, still there have 8 flashboard unit to keep to be intact, and dropping to design attitude automatically, the super doubly transmission of load does not influence when not destroyed by adjacent flashboard unit; The flashboard unit of destroyed, the position and the shape of its destruction have nothing in common with each other; Every construction, the position of welding, be equipped with hidden danger of quality and steel work weldment have all destroyed; Every construction, welding quality are good does not all have damage.Therefore, construction quality is poor, exists many serious quality accident hidden danger, is the basic reason of this having an accident property of bear-trap dam destruction; Error on the operational administrative then is the external cause that destroys, because as long as the operation operating instructions of observing the instruction of county flood control headquarter and clearly stipulating for many years---forbid the high water level operation to move between flood season or storm period, guarantee reservoir safety, current malicious event can be avoided taking place fully, because this lock rules was in accordance with regulations operated safe operation 6 years, and planned comprehensive maintenance and inspection.But from current unexpected accident destruction, also obtain many useful enlightenments: comprehensively innovation improves design, construction, the installation and operation management condition of bear-trap dam, for the innovation and creation automatic sluice gate with buoyancy programmed control provides new approaches and theoretical, practical basis.

In October, 1988, with the name of Yellow River Water Conservancy Committee of Ministry of Water Resources exploration planning and design institute, published " bear-trap dam technological service explanation ", and pointed out: " my institute has more rich practical experience aspect bear-trap dam engineering design and research.Luoyang City's Gold Water River reservoir spillway bear-trap dam of design in 1972 (26 * 6m) and Huixian Shimen Dam flood spillway bear-trap dam of design in 1975 (47 * 6.25-7m), check through construction and long-time running, prove success.What occur on the past bear-trap dam performance is asynchronous, and problem such as self-locking, floating, out of control certainly, poor durability, maintenance difficulty all is resolved basically.Therefore, it is acknowledged as the sign that second generation bear-trap dam is born.My institute has received relevant personnel's interview in more than 30 provinces in all parts of the country, city, county for this reason, and successively provides the drawing of Analysis of Nested Design more than 100 for relevant department, calculated description with exchange data.In order to reduce cost significantly, simultaneously also in order further to promote the development of bear-trap dam, be China's water resources and hydropower construction cause service better, my institute will bear bear-trap dam technical advice and second and third bear-trap dam design objective in generation.Technological service and standard of charge are as follows: (1) bear-trap dam engineering design (span is greater than more than the 50m), will collect design fee than saving 1/2～1/5 of investment cost by the rubber dam of identical discharge type design; (2) based on the novel small power station engineering of bear-trap dam, will collect design fee than 1/3～1/10 of the small power station's engineering economy investment cost that designs routinely; (3) to the newly-designed bear-trap dam engineering consulting of other unit, if can not propose three above improvement ideas and reduce construction investment, same free answer from.General advisory fee is only collected than 1/3～1/10 of investment cost that former design scheme is saved.Cooperate this Service Description, write " bear-trap dam new technology summary and prospect " by the inventor and printed and distributed national units concerned.This paper more comprehensively sums up the evolution and the experience and lessons of China's bear-trap dam, has tentatively proposed the scenario and the improvement idea of third generation bear-trap dam, and the bear-trap dam engineering is combined with the medium and small-scale water and electricity engineering, proposes some new concepts and new approaches.Subsequently, once the demonstration in conjunction with some object of construction production compared, third generation bear-trap dam is carried out more deep, the more exploratory development of system, and write " development of bear-trap dam technology with apply ", publication is outstanding technical journal " water conservancy and hydropower technology " first phase in 1994 in the whole nation, formal for the first time third generation bear-trap dam design scheme and the accompanying drawing of proposing in the literary composition.In a word, the inventor once reached the exploratory development in 20 years to third generation floating gate, it will more perfect than second generation bear-trap dam, more advanced, more economical and safety and reliability, but regrettably still do not have the engineering practice check, the particular content details is also never published, the maximum mistake of third generation bear-trap dam achievement in research, be traditional concept and the Mechanical Builds of yielding to bear-trap dam, the new results of achieving no breakthrough property just change original design, execution conditions, become better and approaching perfection day by day.But, the development of things always has the process of quantitative change to qualitative change, and follows " what negate negates " rule, and it provides abundant foundation and scheme contrast for creation, the invention of automatic sluice gate with buoyancy programmed control, and it is the teacher of funeral affairs that preceding thing is arranged greatly, and what Failure is the mother of success sighs with deep feeling!

The purpose of this invention, widely collect contemporary science and technology progress achievement and bear-trap dam engineering experience exactly, for Hydraulic and Hydro-Power Engineering is built a kind of novel gate with automatic compatible microcomputer remote control of waterpower of contemporary advanced level of creativity and innovation, substitute and be extensive use of the various conventional gate (containing the ship lock gate type) that falls behind with technical-economic index at present, and, keep in repair the replacement door type easy, that application life is the longest, the construction period is the shortest, comprehensive cost is minimum for the Hydraulic and Hydro-Power Engineering construction of 21st century provides a kind of operation safe and reliable to operation.In addition, this invention and a whole set of new technology, new equipment, new technology combines, create a kind of novel movable gate dam hydroelectric project, substitute concrete gate dam hydroelectric project conventional and that still adopt in a large number present countries in the world, and be middle low water head, the construction diversion of hydroelectric project and disposable cut-off cofferdam water retaining generate electricity in advance and start new way, thereby make China in, the small-sized hydropower projects construction will make a breakthrough: go into operation then, build up flood discharge sand washing gate dam engineering (automatic sluice gate with buoyancy programmed control) then, build up the simplification ship lock then, Construction Closure then, utilize the first batch of unit generation in high cofferdam that dams then, supported electrical rolling with electricity in 1 year and raise funds to build up, beginning energy charge income was paid the principal and interest on the loan in the 3rd year.It will make China the waterpower automatic gate and in, the low water head construction of hydropower plant is in world lead level.

The task of this invention, systematically resolve the ten big technical barriers that expose in the bear-trap dam engineering practice exactly comprehensively, make lifting performance, automation mechanized operation runnability, water shutoff performance, maintainability, endurance quality, the uprising stormy waves impact endurance test shock performance of bear-trap dam, anti-silt alluvial performance, and design art moulding, tourist sight, combined energy dissipater, install miniature self-contained hydroelectric generation unit, comprehensive management management, construction technology, construction period, construction costs etc., create to some extent, advance to some extent.And combine with a whole set of new technology, new equipment, new material, new technology, new policy, new concept, make the comprehensive rolling development improvement of China's rivers, " five certainly " engineering mode of go on fund raising voluntarily rapidly, charging, repay voluntarily, build voluntarily, manage voluntarily voluntarily.

This invention has four big name features: first, what it derived from China's first, second and third floating gate in generation grinds examination achievement and engineering experience widely in a large number, its root and basis are bear-trap dams, its lifting operating principle, five-bar mechanism transmission principle and structural load design condition etc. are fully identical with bear-trap dam.Therefore, it can only " float " by surname, promptly presses operating principle, design, the operating experience of bear-trap dam, needn't do any model testing again, just can directly design the automatic sluice gate with buoyancy programmed control that can guarantee safe and reliable operation.Second, its extensive use hydraulics, the principle of structural mechanics and mechanism's mechanics, problem to the bear-trap dam existence, carry out the innovation of system improvement again comprehensively, we can say, remove standardized screw, outside the nut, 99% component are all different with bear-trap dam, it all is record-breaking innovating the improved degree of depth and range, quantitative change produces qualitative change, therefore, can be renamed as " range control automatic gate ", first word of name is " power ", representing that promptly it all is to be undertaken by mechanics principle that all innovations improve, is not arbitrarily to act by subjective wishes, as multi-functional hinge water shutoff combined unit, gentle floating middle carrier bar, universal maintenance bracing or strutting arrangement, permanent sealing water device etc.The 3rd, it is provided with very complicated perfect again multi-functional gallery valve operation management system, makes it carry out the automatic and microcomputer straighforward operation operation of waterpower according to designing program and various design water levels.It is different from traditional waterpower automatic gate, and all the water recast that increases with design containers is an equilibrant force lift gate automatically; New design is then by filling very plastic bottle, the pulling pullswitch of low capacity the communicating pipe of electric wiring of designing program and various water levels, with the special electromagnetic valve of accumulator jar power supply opening, just can operate Pneumatic butterfly valve lift gate automatically, promptly " PROGRAMMED AUTO " is different from traditional " the heavy balance of water is automatic ".The 4th, it has the prerequisite performance of hydraulic gate and feature one fast opening and closing gate, tight sealing water device reliably, favorable durability energy, good construction, installation, maintenance condition, can install Emergency Gate carries out large repairs etc., thereby its category division genus " gate ", and belong to movable dam or movable weir unlike the type of rubber dam, bear-trap dam.In a word, be that science is rigorous again by this four big feature called after " automatic sluice gate with buoyancy programmed control ".

Necessary technical characterictic of the technical scheme of this invention and additional technical feature have following ten:

1. initiate multi-functional permanent hinge water shutoff combined unit, this is a technical and professional very strong patent of invention technology, also is the important symbol that automatic sluice gate with buoyancy programmed control has contemporary advanced level.Bear-trap dam is propped up the combination of hinge form of structure and seal water structure device, once spending more than 20 year time carries out exploratory development, also once conceived many form of structure schemes, but because the constraint of traditional concept and technology, fail to make a breakthrough, in working out manual of the present invention and drawing course in recent years, just progressively improve and be comparatively ideal achievement: the technology that 1. breaks traditions gate props up hinge and transmits point load, the hinge steel pipe that changes communication type into rotates the contact surface supporting, transmit evenly distributed load, eliminate stress to concentrate and destroy a difficult problem; 2. utilize the hinge steel pipe to rotate the tangent line bearing surface, increase the protection of brush chromium layer,, solved the hinge constructional device problem that combines with the seal water structure device as permanent water shutoff; 3. utilize " minute surface sealing " new technology, Molykote, the stainless copper coin of nickel chromium triangle, stainless steel parts and electrodeposited chromium layers antirust etc., at parting place, flashboard unit, sealed-for-life hinge transmission tensile device has been designed in the end that is the hinge steel pipe, and the permanent water shutoff problem of solution seam and plane of rotation, its maximum characteristics are transmission hinge and face mirror obturator, after the program general assembly by design, can not change taking-up, guarantee permanent safe operation, be total to the life-span with reinforced concrete structure, greatly simplified the construction and installation and the maintenance of a hinge water shutoff combined unit; 4. only depending on the hinge at hinge two ends and seat board embedded part to bear the main gate-board hydraulic pressure component (pulling force) that makes progress is safety inadequately, overlap cambered surfaces and end the common tension of axillare weldment so each flashboard unit sets up three, and double notched sill energy dissipating; 5. energy dissipation by aeration and the energy dissipating of water jets bump in order to increase a hinge steel work deflecting flow dam, and with the energy dissipating of main gate-board Lower Half beam and slab structure, the energy dissipating of absorption basin notched sill, form less expensive reasonably novel " combined energy dissipater ", welding triangular prismatic type cast iron detal and taper discharge jet on the hinge welding I beam, and bury underground and carry compressed-air actuated aeration pipe; 6. handling with a water shutoff of hinge plane of rotation intersection, end in the water shutoff of gate pier side is a technical barrier, and present various gates all do not have successful experience, and serious leakage jetting phenomenon all takes place.Use the welded steel structure garden dish of fine finishining and brush chromium layer protection for this reason instead, utilize " minute surface sealing " principle to eliminate Lou jetting phenomenon, and reach permanent water shutoff and long-term maintenance free requirement; 7. install three cover tumblers in the end of gate pier one side hinge: the one, press water is carried sealing device; The 2nd, the compressed air delivery sealing device; The 3rd, gatage discharge indicator.More than the assembling of every structure and process conditions see explanatory note one joint of Fig. 1, Fig. 2.

2. adopt novel main gate-board structure.A large amount of engineering practices of bear-trap dam prove, main gate-board form of structure and shape, lifting performance and security reliability influence to bear-trap dam are very big, brightness tool Shimen Dam flood spillway bear-trap dam particularly, storm wave impact and strong vibrations test have been stood, powerful stormy waves impacts and makes bed rearrangement door body structure and lock wall construction generation sharp pounding and sound, the huge sound is on tenterhooks administrative staff with rocking, though considered the coefficient of impact 1.5 that stormy waves impacts on the structure design, but rupture failure (main gate-board rising 50mm) still takes place in the steel work intermediate chain bar of welding, main gate-board props up hinge stress and concentrates the bulb shape crack that produces to develop to some extent, the epoxy resin sand of seam water shutoff, slurry local failure, the existing bear-trap dam main gate-board design condition incompatibility storm wave impact endurance test shock of proof thus; Secondly, be the prefabricated and unsuitable complexity of hoisting restriction main gate-board shape of construction of main gate-board, size is unsuitable excessive, and it is big to do big improvement difficulty.The main gate-board of automatic sluice gate with buoyancy programmed control improves and moulding at these two technical barriers exactly.At first, the installation technology of main gate-board is improved to clay model moulding pouring construction in place on the spot and the disposable steel work weldment of burying underground, greatly simplify and accelerate construction and installation, and main gate-board cell width, structure length and geomery etc. are not subjected to the hoisting machine tool condition restriction.Next changes the main gate-board top into broken line type, and the high about 800mm of broken line is to satisfy auxiliary gate-board and gentle minimum maintenance requirements of installation space of floating middle carrier bar on the flexible combination type.Its top curve is then by vacuum weir overflow curve condition setting, to reach maximum discharge coefficient.These two conditions combine, certainly leading to main gate-board puts at the most high-grade water level, the about 400mm in underwater will be slipped in its top, when storm wave impacts like this, its retaining hit rigid body plane that face is not the main gate-board cantilever end and with reinforced concrete structure on auxiliary gate-board form the horn shape rigid body, but sharp mouth shape curved body, the first half of storm impact climbs along curved surface and crosses the top and descend like this, do not produce the reaction force of storm impact, the Lower Half of storm impact is then made tangential motion along auxiliary gate-board on the flexible combination type, and defeat a force with a tenderness, the reaction force of generation is obviously very little.But also produce a very big side effect, promptly huge repeatedly storm wave fluctuation, certainly will drive main gate-board fluctuates, the last auxiliary gate-board of bullet flexibility wants the bigger elasticity of specific rigidity structure generation to shake distortion altogether, therefore, one time storm wave just may be the hydraulic type rubber water shutoff wear-out failure of gate pier both sides, for this reason, adopted three remedial measures: the one, in the main gate-board top-side uprising stormy waves impact elasticity locking stopping means is set, limit significantly free floating of main gate-board, and unite anti-resistance with the water shutoff of hydraulic type rubber; The 2nd, descending auxiliary gate-board to prop up on the hinge free bearing girder steel weldment, cambered surface is set ends the axillare elastic limit device, and restriction is descended freely swinging of secondary lock flashboard and is produced covibration; The 3rd, effective measures are in time to utilize the about 500mm of microcomputer remote handling system landing automatic sluice gate with buoyancy programmed control, local unlatching earial drainage, and storm wave just is difficult to impact gate.In a word, uprising stormy waves impacts and shaking device is to alleviate its influence as far as possible, is major action of automatic sluice gate with buoyancy programmed control design model.Once more, the main gate-board Lower Half is made into the beam and slab type energy-dissipating structure, both saved reinforcing bar and concrete amount, be beneficial to again and form novel " combined energy dissipater ", but then should make the continuous hollow plated construction in high water head earial drainage condition, and utilize " combined energy dissipater " of choosing the aerial energy dissipating of stream bank.Also have, the support pattern of main gate-board improves to some extent, and main gate-board is droped to the ground the position top-supported at following auxiliary gate-board hinge weldment, and steel to steel line contact supporting is eliminated the problem of stress concentration of point load, and set up old tire rubber tile elastic cushion block, eliminates impact load.In addition, supporting beam forward the moving of trying one's best in middle part reduced the top-supported span, adapts to the big characteristics of overflow depth of water flowing pressure.Its specification specified is seen the relevant explanatory note of Fig. 1, Fig. 3, Fig. 4.

3. the auxiliary gate-board structure replaces the reinforced concrete structure flashboard on the employing flexible combination type.It derives from the engineering practice of rubber dam and gentle abdomen bear-trap dam and grinds the examination achievement, but not that simple the transplanting applied mechanically, but maximize favourable factors and minimize unfavourable ones, and in conjunction with the runnability of automatic sluice gate with buoyancy programmed control, support maintenance condition and installation technology characteristics, innovated and formed a complete set of, float fixedly connecting device of middle carrier bar, chain form hydraulic type rubber sealing water device, special arc steel work as gentle, thereby produce qualitative leap, have very big novelty, creativeness and practicality.Its technical characterictic is: 1. flexible flashboard is that the wire rope bonding by the thick nylon cloth rubber tile of 7～12mm and diameter 6.2～12.5mm is combined into, rubber tile is regardless of the flashboard unit, the bonding view picture that is unified into, its width equate that with the gate overall width other widens 600mm and uses as side seal water is folding; But the configuration of wire rope is then divided by the flashboard unit, each flashboard unit is provided with 4, mainly satisfy the service requirement that uprising stormy waves impacts, and prevent the aging permanent deformation that produces of nylon rubber plate, make the dash height of gate constantly increase variation through the long-time running meeting.The full-length of wire rope must strictly be controlled, and every wire rope needs to be woven into ring-type by the experienced operator, the arc steel work that is fixed on two ends with 4 special pulleys is connecting device fixedly, when impacting in order to adapt to the uprising stormy waves of wire rope, produce powerful concentrated pulling force, set up the shearing resistance burnished bolt and strengthen connection, and with 120 * 5mm nylon cloth rubber tile that the wire rope bonding is fixing.2. its two ends connect with special arc steel work connecting device, and this device also has flashboard and turns to tension, bending resistance, side seal water arc transition, the fixing hinged and multiple function of main gate-board top elastomeric bearing of fine motion of strengthening of wire rope.In addition, the length that must be pointed out its every joint only is 2.2m, so that stagger with the seam of flashboard unit, part plays strengthens the hinged globality connection effect of fine motion.3. the side seal water of auxiliary gate-board connection processing is a technical barrier on the flexible combination type, should satisfy flashboard plastic deformation condition, side seal water with main gate-board and following auxiliary gate-board has continuity and bending again, rotate, stretching good linking, through multi-scheme research relatively, adopt chain form hydraulic type rubber side seal water device at last, it is to utilize the two pass bolt, two sleeve backing plates, double-layer rubber plate and long bar steel plate connect fixedly hydraulic type rubber water shutoff, and enhancing lateral stiffness, prevent excessive Free Transform and leak, utilize the anticaustic power of hydraulic type rubber water shutoff and frictional resistance supporting-point again as flexible flashboard, thereby improve the stability of sealing water device, the Free Transform that unlikely generation is excessive and leaking in a large number.4. as the ingredient of auxiliary gate-board on the flexible combination type, be exactly gentle floating middle carrier bar, both interdependences, mutual restriction, moulding mutually, inseparable.Its structure assembling and process conditions are seen the explanatory note of Fig. 4.

4. adopt gentle floating middle carrier bar to come instead of steel structure intermediate chain bar.The most high-grade water level at automatic sluice gate with buoyancy programmed control is put, and it is the ingredient of auxiliary gate-board on the flexible combination type, only in the gate lifting process neutralization position of droping to the ground, just demonstrating the shape and the function of gentle floating centre carrier bar.It has similar function with the steel work intermediate chain bar of the second generation five connecting rod bear-trap dams: be convenient to be connected upper and lower auxiliary gate-board and water shutoff; Constitute five side rod motion of mechanism mechanism, transmit the buoyancy and the water pressure of each member respectively; Through a large amount of model investigations and electronic computer computing check, it greatly improves lifting, the runnability of bear-trap dam; It can cancel reservoir water-filling start gate, rises gate automatically and used the dynamic head design instead; Strengthen bear-trap dam globality rigidity, help eliminating the serious asynchrony phenomenon of bear-trap dam.But steel work intermediate chain bar handles for construction, manufacturing, installation, the seam water shutoff of bear-trap dam, and uprising stormy waves impact and vibrations, operational management and maintenance etc. bring numerous unfavorable conditions, and the rupture failure of having an accident property.This invention is maximized favourable factors and minimized unfavourable ones, and resolve these technical barriers with flying colors, it is characterized in that: 1. the height of gentle floating middle carrier bar is about 800～1000mm, to grow one times than the steel work intermediate chain bar of bear-trap dam, help eliminating " reignition head ", and when satisfying universal maintenance bracing or strutting arrangement and using, auxiliary gate-board under the unlikely drive is also created the better space condition for maintenance; 2. the effect of plastic pipe is to strengthen lateral stiffness and buoyancy moulding, and the two ends of every joint plastic pipe will seal with the hard plastic board hot weld, and stick on securely on the nylon rubber plate with bonding agent and rubber tile; 3. in gentle floating middle carrier bar scope, ageing-resistant foamed plastic buoyancy aid, the about 400 * 100mm of its cross dimensions is cemented on the nylon rubber plate with bonding agent and rubber tile, to reach buoyancy moulding effect; 4. special arc steel work weldment is a straight forming and transmit to divide key parts to water pressure, and its cambered surface length is slightly than the arc steel work at top fixedly about the long 100mm of connecting device.The structure assembling and the process conditions of gentle floating middle carrier bar are seen the relevant explanatory note of Fig. 4.

5. adopt novel auxiliary gate-board down, substitute the board-like structure of steel concrete of four-point supporting.The four-point supporting structure not only produces huge point load at a hinged bearing place, need a large amount of radiation reinforcing bar of configuration, and, adjust requirement in order to satisfy cracking resistance because flashboard thickness is limited, need a lot of two-way concrete slab of configuration, reinforcing bar density is very big, difficulty of construction is also big, once causes serious quality accident and rupture failure, if the flashboard cell width adds is twice, then problem can give prominence to and be difficult to handle more, must improve a form of structure and a hinge form.The present invention improves and clay model molding construction process modification staff in place on the spot from a hinge, be improved to the board-like reinforced concrete structure of optimization type simply supported beam, it is characterized in that: 1. high accuracy standard unit mould prefabrication and lifting technology, be improved to clay model moulding continuity construction technology in place on the spot, this is the innovation and the breakthrough of most critical, thereby greatly simplify construction and installation, reduction of erection time and reduction cost; The evenly distributed load transmission of 2. permanent hinge water shutoff combined unit and gentle floating middle carrier bar, for selecting for use of optimization type simply supported beam plated construction created essential precondition, the height of beam slab can be selected by optimum reinforcement ratio like this, expectation can be saved amount of reinforcement more than 50%, checks also very favourable to cracking resistance; 3. the vertical and horizontal section shape of beam and slab structure is seen Fig. 4, shown in Figure 5, the span of its position supporting-point of droping to the ground, and this is one of flexural strength essential condition, will dwindle more than 1/3 than traditional design; 4. the supporting of main gate-board top-supported and universal maintenance support all is located at down on the auxiliary gate-board hinge weldment, and be convenient to stress diffusion and simplified structure and arrange, also be a key character.

6. adopt novel sealing water device to substitute conventional sealing water device.One of maximum characteristics of bear-trap dam are that the seal water structure device is of a great variety, and it is big to make installation difficulty, and application life is short, and maintenance changes inconvenience, and the total cost of seal water structure device accounts for about 1/3 of door body structure total cost.This invention breaks through the process conditions of traditional concept and technology, seal water structure more than 90% is improved to permanent seal water structure device, can move continuously for a long time, need not keep in repair and change, has the feature that is total to the life-span with reinforced concrete structure, thereby greatly simplify construction and installation, reduce maintenance management personnel and expense, have very high practicality and economic benefit, it is characterized in that: 1. a hinge seal water structure device of main gate-board and following auxiliary gate-board, be improved to the double permanent seal water structure device of steel to steel line contact supporting, and " the minute surface sealing " of the stainless copper washer of supporting employing nickel chromium triangle, the permanent sliding agent of molybdenum bisuphide, new technologies such as stainless steel parts and brush chromium layer make the durability of whole hinge water shutoff combined unit reach hundreds of years; 2. the seam water shutoff between the main gate-board unit is improved to steel mesh reinforcement and cooperates the shutoff of steel fibre coloured cement mortar arch, the colored bulb decoration reaches and the requirement in life-span altogether of steel concrete flashboard, in case local damage also is easy to repair.It derives from the practical experience of bear-trap dam epoxy resin mortar shutoff, impacts and the vibrations check through strong storm wave, has only a small amount of damage, and is most intact.3. the side seal water of auxiliary gate-board on main gate-board and the flexible combination type, be improved to hydraulic type rubber seal water structure device, during gate lifting operation, the closing presure water source makes the water shutoff rubber separate with the lock wall, reduces the wearing and tearing and the frictional resistance of water shutoff rubber; When the closing gate dash, open pressure water source, make water shutoff rubber jam-packed, and reach good water sealing effect, this is the technical new breakthrough of large-scale activity gate water shutoff, particularly a main gate-board side seal water and the permanent sealing water device of a steel disc structure use that matches of hinge plane of rotation intersection, end will make the buoyancy programmed control lock eliminate Lou jetting phenomenon fully, and this is that present various gate all is difficult to accomplish.4. descend the sealing water device of auxiliary gate-board unit seam crossing more to simplify, central space is the formwork for placing that the type of making is mixed in the prefabricated thick bamboo tube skeleton pitch wood chip heating of steel form, and the top seam is then used the shutoff of branded oil felt.5. descend the side seal water of auxiliary gate-board, because loading and unloading change condition restriction, should not adopt the water shutoff of hydraulic type rubber, use the seal water structure device of ageing-resistant plastic pipe and rubber cushion blocks elastic compression instead, wherein imbed the STAINLESS STEEL NUTS in the concrete, need to be cemented on the angle steel weldment with powerful bonding agent earlier, and in the end of nut with the bonding shutoff of stamping forming tin plate cap.The assembling of novel seal water structure and process conditions are seen the explanatory note of Fig. 6.

7. initiative main gate-board i beam rotary type construction platform mould is the fan-shaped water shutoff work plane service of the high-quality high accuracy of gate pier both sides.The engineering practice of bear-trap dam proves: no matter workman's technical level how, well construction howsoever, because the accumulated error of the deviation of the rotational plane of main gate-board side seal water steel knot embedded part and the construction deviation of the fan-shaped water shutoff work plane of gate pier, often cause the fan-shaped water shutoff work plane generation of side seal water steel work embedded part and gate pier part to bump card and cause the scratch that is difficult to see, and make water shutoff rubber squeeze and destroy, the dash height of bear-trap dam is big more, and problem is outstanding more, serious more.It is consistent with the installation deviation of rotating construction platform mould that this invention is exactly the planeness deviation that the large tracts of land work high above the ground of the fan-shaped water shutoff work plane of gate pier is produced, this is easy to accomplish, because the planeness of gate pier shape water shutoff work plane is to wipe mensuration off by rotating construction platform mould, later stage, with second stage concrete main gate-board i beam rotary type construction platform mould is connected with main gate-board, can guarantees its high-quality high-precision requirement.Must be pointed out, in order to adapt to the execution conditions of turntable mould, the wall body structure and the technological process of the fan-shaped water shutoff work plane of gate pier must be improved: in the standard size scope of fan-shaped working face, reserve the dark steel mesh reinforcement second stage concrete hole groove of about 50mm, and bury the joint bar of sufficient amount underground; Before the construction basal plane hacking flushing, after weld fixedly steel mesh reinforcement immediately, and with thicker fine concrete (need mix the early strength admixture of some) placement in layers to the steel mesh reinforcement inner face; And then layering metal binding wire net from bottom to top, and the floating cement mortar of standard baseline of pressing the turntable mould is in time checked its planeness with turntable mould standard plank basal plane after the initial set, and local failure in time repairs; Every layer of initial setting time and begin to fill period of upper strata cement mortar is according to temperature condition at that time, by the technician on duty decision of signing; Whole fan-shaped working face, must be that three-shift system is worked continuously, the centre does not allow to hold up work for lack of material, after all construction is finished, check planeness by the quality inspection inspector with the turntable mould immediately, to in time polish processing if the partial deviations value surpasses permissible value, can't handle, then need destroy construction again if deviate is very big; Be up to the standards, hang up straw mat watering maintenance seven days immediately; The smoothness of this fan-shaped water shutoff work plane is brushed ageing-resistant, the anti-new coating that tans by the sun and is guaranteed.The feature that this cover rotates construction platform mould is: standing tree mould 1. in place is on the spot built the wide steel concrete I-shaped beam of 800mm, its appearance profile and main gate-board are just the same, and have buried water shutoff angle steel weldment and the uprising stormy waves steel structure support weldment towards the elastic locking stopping means underground by designing requirement; 2. install with the screw of side seal water angle steel and fix a straight wooden lath datum, as the main foundation of rotating construction platform modulo n check and the fan-shaped water shutoff work plane of control; Welding simultaneously is temporary rod, scaffold fixedly, safety net and pedal; 3. reserve a hole for hoist and frame bolt built-in fitting at gate pier top outrigger base, install the manual and electric dual-purpose hoist engine of an about 1000kg of pulling force,, operate and rotate construction platform mould by being installed in 4 multiplying power assembly pulleys on the steel structure support weldment.Also must point out emphatically, in order to prevent just in case, on the gate floor of steel concrete I-shaped back portion bearing position, place a collection of old tire, prevent the impact damage of degenerating, and be used round log and support auxiliaryly, guarantee construction safety.

8. initiate universal maintenance bracing or strutting arrangement, this is that automatic sluice gate with buoyancy programmed control is applied and " maintenance packet " promises to undertake indispensable technical characterictic.The engineering practice of bear-trap dam shows that bear-trap dam is independently to be assembled into the flashboard unit by dozens of, and weight reaches hundreds of tons and even goes up kiloton, once uses traditional crane lifting maintenance, and difficulty is very big, and expense is very high, and is chronic.Afterwards, once be improved to extensive manually-operated rotary type bracing or strutting arrangement, but poor effect, once having an accident property destruction.Therefore, will be the huge heavy again flashboard unit of dozens of, need not any lifting facility, only depend on floating and lifting of gate self, while is support fixation equably, and drop to exactly on the special self-aligning spherical support plate, this high precision universal maintenance bracing or strutting arrangement must have a whole set of strict process flow process to guarantee.So-called universal is exactly tens of seats and even up to a hundred automatic sluice gate with buoyancy programmed control, a shared cover maintenance bracing or strutting arrangement, and periodic maintenance is changed wearing terrain manage streamlined socialized service system does not need management unit to work hard and starts.Its technical characterictic is: 1. universal steel pipe supporting member, by the high-quality seamless steel pipe and the accurately machined self-aligning spherical support plate of full-length, welding mounting, micrometer adjusting screw junction plate, WELD NUTS etc., on special high accuracy platform mould, assemble and be welded into, must strict control and eliminate welding deformation, this is standardized high precision universal member, it is common to all automatic sluice gate with buoyancy programmed control in certain serial scope, except that first gate, other needn't reproduce, and use from special warehouse to get final product; 2. accurately machined spill self-aligning spherical support seat board is wanted strict being welded on down on the hinge of auxiliary gate-board by the design centre distance between centers of tracks, and is cooperated welding with the elasticity limiting plate, the sphere of brush chromium layer protection after the assay was approved; 3. on the platform mould of standard, the fixed earlier firmly fixing following auxiliary gate-board that welds that assembled props up hinge water shutoff combined unit, the shown standard obliquity of plank sectional model by 1: 1, the universal steel pipe of fit on supports, adjust positioning and fixing main gate-board top girder steel weldment then, through after the assay was approved, fix connecting the steel plate welding, use 3 the temporary fixed support seat board of bolt weldments simultaneously.Here the technological process of most critical is: because the steel work weldment is transported, move, bump, influences such as the temperature difference, add the distortion that concreting is vibrated and produced, and the cumulative departure of alignment error etc., cause each universal steel pipe fulcrum ball face central point that identical air coordinates position can not be arranged, what have may substantially exceed deviation allowable value, therefore, each buoyancy programmed control gate is before construction finishes to check and accept, once design the operation operation test of dash position, universal steel pipe is installed after qualified immediately to be supported, and with each fulcrum ball surface bearing central point adjustment point-blank with micrometer adjusting screw, open a sluice gate the upper pond level that lands then, at this moment automatic sluice gate with buoyancy programmed control will land and corresponding landing with upper pond level, when dropping to apart from the design maintenance, main gate-board top curve section supports height mark (red setting-out) when still 50mm being arranged, stop to land and wearing the deviate that sphere central point and spill self-aligning spherical support central point are respectively supported in the diving dress submarine inspection, place on record one by one by the diver; If it is excessive that deviate all exceeds standard, then barrier gate rises gate, raises at the water surface and integrates lattice; If have only the minority deviate big; it is qualified then to be adjusted under water by the diver; slowly landing supports subsequently, but main gate-board has only the fraction weight supporting stressed also at water float; at this moment the diver can knock with weight; make the bearing surface normotopia that fits like a glove, so that upper pond level is when dropping to lowest water level, the electric welder goes down each is supported the seat board weldment and connects steel plate and weld; and 3 temporary fixed bolts are changed weldering be shearing resistance anchor weldering screw, brush the protection of novel antirust material at last.Last barrier gate rises gate, and measures the deviate that respectively supports sphere central point and standard straight-line, and number record is on record one by one, during for periodic inspection support later on, the foundation of adjusting is installed.But operation operation and storm wave impact endurance test shock through decades may produce the structure permanent deformation deviation of accumulation, and therefore, when each thereafter maintenance was supported, all needing did not have too great deviations by diver's submarine inspection, and the side allows the emptying water level to overhaul support.Here it is guarantees that this overlaps whole technological processes of the safe and reliable use of universal maintenance bracing or strutting arrangement.If run counter to this technological process, must cause supporting individually overburden and destroy and the local failure of main flow plate.

9. create a kind of novel two pass cable wire nylon rubber plate Emergency Gate, this is an additional technical feature.When the design automatic sluice gate with buoyancy programmed control, manage also can regularly overhaul support and change the damage component without the Emergency Gate dash as far as possible, for example match with the electromechanical equipment overhaul phase, scheduled overhaul in 20～30 years once empties to upper pond level below the gate floor and to get final product.But the river course that some is low-lying, the gate dam engineering of shipping, lake, seashore, it is a lot of that lowest water level will exceed gate floor, and Emergency Gate must be set could periodic inspection be supported.Still do not have a good method type of becoming reconciled in the world today and solve the access door problem of large span shutter.According to the engineering experience of external cable wire veneer rubber dam, in conjunction with the condition of applying and the design model characteristics of automatic sluice gate with buoyancy programmed control, concept design should the invention.This is an additional technical feature, does not have its automatic sluice gate with buoyancy programmed control also can exist, and just limits its extent of spreading amd application.It is characterized in that: 1. two bearer cables are fixed by manpower stretch-draw on the reinforcement anchoring part with special stretching screw, and the connection of cable wire and nylon rubber plate is fixed with special bent plate weldment and double nut; 2. for the ease of installing, transportation and keeping, the nylon rubber door-plate can be assembled into by 1～7, and its assembly mode sees that Fig. 8 assembles sketch, and the junction compresses water shutoff with standard bolt and packing ring and gets final product; 3. special doorframe built-in fitting is set, and nylon rubber plate and the bolted on connection and the dismounting of built-in fitting are under water finished by the workman who wears diving dress; 4. utilize buoyancy programmed control gate main gate-board top curve surface shape and special arc steel work weldment, special wooden voussoir is installed, directly bear a part of water pressure, the force-bearing situation and the load that can improve nylon rubber plate and cable wire preferably distribute, and improve its security reliability; 5. this invention can be used for span 12～152m, and the sluicing aperture of dash height 2～8m is as Emergency Gate; But if can form the seriation standard fitting, unified preparation, keeping and socialization overhaul service then can be common to all automatic sluice gate with buoyancy programmed control.

10. multi-functional gallery, pipeline, valve, electromechanical equipment Operational Management System are set, are the modernization operation operation of gate, comprehensive management management and tourist sight are created essential condition.Bear-trap dam and all waterpower automatic gates all have own unique collector drain and valve operation management system of filling, but too simply extensive, function is imperfection very, and it is many because of difficult and inconvenient to cause for the operation operational management.This Innovation System will be the most advanced and the most perfect Operational Management System of function in the world today: its existing hydraulic automatic (unattended) operation operational system and microcomputer straighforward operation management system; Miniature self-contained hydroelectric generation unit (self-powered's power supply) is arranged again, diving pump station, pipeline booster station, high pressure water pot and pressure water pipe net, for water shutoff rubber press water, living water, agricultural sprinkling irrigation are supplied water, the tourist sight injection water, regular channel sand-flushing desilting jetting etc. provides cheap water source; Also have mini air compressor group, high pressure tank and gas transmission pipeline network, prevent that for Pneumatic butterfly valve, pressure-air spray freezing and compressed air aeration provides safe and reliable source of the gas; Also have traffic, observation, draining, irrigation gallery system, fill collector drain valve operation management system and gate floor hollowcore slab system.The layout of this cover valve, gallery Operational Management System, section grade separation layout and thin portion assembly relation are seen Fig. 9, Figure 10, shown in Figure 11 and relevant explanatory note.Its technical characterictic is: 1. novel hydraulic automatic operating system and device are set, realize the water discharging valve that fills of hydraulic automatic operation operation, use inflatable type Pneumatic butterfly valve (LCL-10 type without exception instead with contemporary advanced level, Jiangsu Province's Yixing City first Machinery Plant of Light Industry's innovation product, latus rectum  50mm～ 500mm), so only needs the very storage battery of low capacity, open ventilating pipe with electromagnetic valve, just can operate many cover inflatable type Pneumatic butterfly valves, thereby realize waterpower automatic lifting gate.Simple designing program is: when normal operation, all water discharging valves are all closed, and inlet valve is opened, and automatic sluice gate with buoyancy programmed control is the automatic lifting dash with the variation of upper pond level, does not need personal management; When coming the water yield to surpass water supply volumes such as generating irrigation water supply, water level surpasses door top overflow, and the autobalance turnover water yield does not need personal management yet; When flood comes amount bigger, water level reaches design flood discharge water level, at this moment current flow into plastic bottle by ad hoc communicating pipe automatically, water-filled weight can be drawn back pullswitch automatically, thereby special electromagnetic valve is opened, just can close the Pneumatic butterfly valve of water-filling automatically, and open a Pneumatic butterfly valve of hinge jet water course bump energy dissipating gutter and the Pneumatic butterfly valve in gate pier draining duct simultaneously, automatic sluice gate with buoyancy programmed control just can be carried out landing flood discharge automatically; After the flood peak or in normal earial drainage process, when upper pond level is reduced to minimum emerging sharp limiting water level, device with float in ad hoc communicating pipe can draw back pullswitch automatically, thereby by predetermined designing program, one after the other the special electromagnetic valve of appendix is opened, closed the Pneumatic butterfly valve in relevant draining duct earlier, after open the Pneumatic butterfly valve of inlet channel, automatic sluice gate with buoyancy programmed control can rise dash fast, and with the variation of water level free floating, do not need personnel to manage; If just in case extra torrential rain and flood attack occur, reservoir level soars to extreme high water, at this moment, though the opened operation of the first cover hydraulic automatic device, but because sinking speed slowly or chance failure occurs, gate is not standard-sized sheet flood discharge as yet, in order to ensure the engineering flood control safety, designed the 3rd cover hydraulic automatic operating means (the waterpower automatic gate in past does not generally all have this cover safeties), current flow into plastic bottle by ad hoc communicating pipe, water-filled weight can be drawn back pullswitch automatically, the power supply opening that is provided by the miniature self-contained hydroelectric generation unit of installing in the gate pier is by the disk jet gate slot cantilever fixed wheel gate of electronic cylinder operation, this gate is arranged on the large-scale inertia drainage pipe that waits and chooses the Liu Kan exit, can guarantee that the buoyancy programmed control automatic brake steadily drops to the end apace and carries out safe flood discharge, adopting the large-scale inertia drainage pipe that waits in the waterpower automatic gate is initiative.2. microcomputer straighforward operation management system and corollary apparatus are set, not only whole operational administratives of automatic sluice gate with buoyancy programmed control can be by the microcomputer straighforward operation, other facilities such as hydroelectric generation unit, relevant pumping plant, row's silt sand surfing pipe special valve, the feed ditch diversion, the energy dissipating of injection water bump, energy dissipation by aeration, the pressure pipeline sprinkling irrigation, tourist sight lamp decoration etc., also by the microcomputer straighforward operation, also have hydraulic automatic system and device also can promptly when reservoir level does not reach the automatic design water level of waterpower as yet, can shift to an earlier date straighforward operation and open a sluice gate earial drainage by microcomputer remote control dual operation, emptying goes out bigger storage capacity, so that increase the flood detention benefit.But the electric part of this cover microcomputer straighforward operation management system is installed, generally do not carry out (except the Important Project) synchronously with engineering construction, its expense is disregarded the investment of people's engineering, but after engineering is built up the operation several years, extend installation by the fund that rolling development is raised, and carry out specialized designs and examination is installed according to the practical operating conditions of every engineering by the Electrical Engineer.Also to point out, the significant feature of this cover microcomputer straighforward operation, be that automatic sluice gate with buoyancy programmed control can be realized soon fruitfully, lifting and local the unlatching are moved flexibly at a slow speed, and control by the disk jet gate slot cantilever fixed wheel gate of inertia drainage pipe outlet such as large-scale, this gate is operated by the electric cylinder, and this is the new technology of an initiative.3. miniature self-contained hydroelectric generation unit is installed in the headspace of gate pier, carry out low water head, small-power generating, for gate automation mechanized operation operation and gate dam engineering management unit carry out the comprehensive management service, cheapness power supply reliably again is provided, this is initiative on world's gate construction history.Tentatively select " the miniature self-contained hydraulic generator unit of full-tubular " of the development of water machine teaching and research room of Gansu Polytechnical Univ for use, its head 1～7m, unit capacity 1～100kW; When head is higher, " the full-automatic self-contained minitype wheel generator group of MAA-1 type " that then can adopt Hubei Province automation equipment factory of Lu Shui multi-purpose project office to produce, its head 6～20m, unit capacity 5～40kW.In addition, consider from the development strategy of small watershed and step engineering rolling development, on the gate pier limit of a bank, reserve small hydropower station unit position, see and raise fund with comprehensive management rolling development and mortgage loan shown in Figure 11 mark 8～12, by the water amount of power generating that small watershed is planned and little multi-reservoir can provide, small power station's engineering that design-build is supporting provides new model for water conservancy industry and water project management move towards commercial running.Electricity is arranged, water is arranged, have to roll and raise fund and the technician, a kind of newborn enterprise-power supply of socialist market economy, waters supply, for feed, for food, cooling storehouse, in conjunction with modernization breed, the comprehensive industrial corporation of planting, it is flourishing to be bound to.This is maximum economic benefit and the social benefit that is caused out by emerging electricity.4. living water and industrial or agricultural water supply Operational Management System, utilize submersible pump, pipeline force (forcing) pump, normal pressure water pot and the pipeline system of automatic sluice gate with buoyancy programmed control operation operation, carry out small-scale, life tap water among a small circle and the service of farmland sprinkling irrigation water earlier, after progressively promote the expansion service zone, after treating that supporting small hydropower station builds up, then develop into specialized living water, indusqtrial water supply and agricultural sprinkling irrigation, drip irrigation socialized service system, the advantage of performance basic industry of water conservancy.5. the development modernization is cultured and the plantation system of operation and management, utilize cheap power supply reliably, the pressure sprinkling irrigation, the mist irrigation source, waters, reservoir area and absorption basin waters, doing medium scale net cage and absorption basin earlier breeds fish, investment then, make a lot of money then, work as tap with this and drive other biological chain aquaculture and brooder, fruit-bearing forest plant husbandry, it is managed the layout scope and is clearly stipulated by the planning and designing file, in principle with the technology investment joint venture of relevant universities and colleges, and near resident is carried out technical training manage with demonstration, also be that the water conservancy industry worker moves towards the enterprise management only way.6. tourist sight and tourist service facility, this is the new problem that contemporary Hydraulic and Hydro-Power Engineering construction must think better of.Automatic sluice gate with buoyancy programmed control is in conjunction with the gate pier management house, pumping plant, road bridge, the fruit-bearing forest green area, the building artistic design of culture zone, constituted a landscape engineering that ornamental value is arranged very much, particularly main gate-board overflow, the energy dissipating of injection water bump, the high-pressure water spray facility, cooperate modern rainbow color lamp to shine mutually again, constitute the very magnificent dynamic solid tourist sight of a width of cloth, and the fund of utilizing rolling development to raise is built some amusement on water places again, the park of fishing, the perpetual bloom park, dining room waterborne, the village etc. of spending holidays will form the water conservancy and hydropower benefit, the new model of modernization breeding and planting benefit and three combinations of social tourism benefit.7. traffic, inspection, observation gallery system, each gate pier increases two stair wells and corresponding access gallery and scope, and administrative staff can operate, check and observe that this is that design in the past is unprecedented easily to relevant position.8. impinging jet energy dissipating and channel sand-flushing desilting pipeline valve system, this is seldom to consider in the general gate design.In order to guarantee that the impinging jet energy dissipating has enough pressure water sources, the hemisphere valve that the special pressure waterpipe is set and operates by diving sealing electric cylinder.When automatic sluice gate with buoyancy programmed control rise dash, but copper nozzle on the spiral cover repacks the spraying view into, and injecting time and length can be controlled by the microcomputer straighforward operation.End on the gate floor is provided with the channel sand-flushing desilting pipeline, in the exit of bank gate pier, the control of disk jet gate slot cantilever fixed wheel gate is set, by electronic cylinder operation.In order to improve the channel sand-flushing desilting effect, can cooperate the jet pumping station regularly to open a sluice gate the flood discharge channel sand-flushing desilting, make it have anti-silt alluvial performance.9. the problem that is provided with of traffic highway bridge is not built road bridge in principle simultaneously, because its cost is approaching or surpass automatic sluice gate with buoyancy programmed control, and one of great advantage of this gate is exactly a large span waterpower automatic lifting, saves many gate piers and frame bridge engineering quantity.But consider the needs of socio-economic development, reserve the condition of bridge construction on the gate pier, this bridge can only be large-scale arch bridge, novel prestressed reinforced concrete box shaped bridge or cable stayed bridge, and promptly middle should not have gate pier.If more bridge pier must be set, can change into the power of disappearing and let out end and build the simply-built highway bridge.

Of the present invention excellent with conspicuous characteristics, have eight: it is safe and reliable 1. to operate runnability, under any pernicious disaster scenarios it, (arrange ice, serious silt alluvial, the bed load of flood tide as violent earthquake, extraodinary flood, ice flood, power circuit interruption etc.), can both carry out normal running operation and hydraulic automatic fast lifting, and can be stabilized in different opening control discharge; 2. application life is very long, wear-resisting anti-freezing property was very high, generally can use continuously 100～500 years, wherein changed auxiliary gate-board on side seal water rubber and the flexible combination type every 20～30 years, and to a small amount of steel work embedded part surface brush coating protection, maintenance capacity and maintenance cost are all less; 3. the design span of gate can reach 100～150m, and the dash height can reach 10-20m, can be built into the waterpower automatic gate of maximum port size in the world; 4. the duration the shortest, about 3～6 months of the duration of a large-scale automatic sluice gate with buoyancy programmed control engineering (containing the water conservancy project structure), the construction and installation of gate can be carried out with hydro-structure continuous productive process and in place on the spot the intersection, other gates can't be accomplished; 5. cost is minimum, countries in the world are consistent at present generally acknowledges, rubber dam is most economical a kind of gate dam, generally than conventional gate dam saving investment 30～70%, save steel 30～75%, cement 30～50%, timber about 60%, but contrast according to one's analysis, the automatic sluice gate with buoyancy programmed control (containing the water conservancy project structure) of same flood discharge scale (non-port size) will also reduce investment outlay 10～30% than rubber dam; 6. the discharge coefficient and the novel combined energy dissipater benefit that have the vacuum weir promptly reduce by 30% lock hole width and absorption basin length than the broad crested weir form that conventional gate adopted; 7. have higher comprehensive management and rolling development benefit, owing in gate pier, installed the miniature self-contained water generator group of easy full-tubular, living water and industrial or agricultural water supply pumping station system, and in the overall plan design, tourist sight, industrial and commercial market, traffic road and bridge and modernization breed, planting base have been set up, utilize water, electricity, fund, science and technology, talent advantage, be comprehensive management and rolling development creation ten minutes advantage, estimate to pay off in 2～4 years financing of projects principal and interest, can roll in 5～8 years and to build up water conservancy type integrated farm-industry-commerce enterprise; 8. have practicality and very high promotional value widely, the barrage sluice that not only can be used for various river courses, area, river mouth tide-block sluice, the large-scale ship lock of modernization, also be specially adapted to detention basin flood-diversion sluice, reservoir spillway sluice, the irrigation water-drawing gate of fully-loaded stream, check gate, and the multi-functional barrage of novel hydroelectric project, water conservancy diversion, flood discharge, towards the silt lock.In addition, not only can on middle-size and small-size Hydraulic and Hydro-Power Engineering, be applicable, also can on large-scale, huge Hydraulic and Hydro-Power Engineering, be applicable.
