Summary of the invention

The purpose of this utility model is the ecosystem regulation structure providing a kind of water, and allow the surface water infiltrate deeper subsurface water layer, deep water table rises, and may just sink in stratum in unlikely continuation, and when infiltrating the water table of shallow-layer, the groundwater table of shallow-layer rises.

The purpose of this utility model realizes like this, the ecosystem regulation structure of described a kind of water, being included in low-lyingly has surface water place or has the retaining dykes and dams that the riverbed in streams is built, the surface water is stored in retaining dykes and dams, it is characterized in that: in retaining dykes and dams, excavation has a plurality of infiltration well, described infiltration well, down into water table, makes the surface water in retaining dykes and dams connect with water table, and the surface water penetrates into water table after being filtered by the penetration material permeated in well; In infiltration well, put into osmos tube, fill up penetration material between the borehole wall of osmos tube and infiltration well, described osmos tube is provided with permeable hole.

Described retaining dykes and dams comprise first floor retaining dykes and dams, second layer retaining dykes and dams and third layer retaining dykes and dams, described first floor retaining dykes and dams, second layer retaining dykes and dams, third layer retaining dykes and dams are spaced structure with staged from high to low and form, first floor retaining dykes and dams have the biological migration hole of first floor, second layer retaining dykes and dams have the biological migration hole of the second layer, and third layer retaining dykes and dams have the biological migration hole of third layer; The biological migration hole of first floor is greater than the biological migration hole of the second layer; The biological migration hole of third layer can not be greater than the biological migration hole of the second layer.

Feature of the present utility model and advantage are: having the low-lying place of the surface water as lake, pond, river (small stream) bed etc., cutter infiltration well depth enters water table, infiltration well fills up penetration material, as sandstone, permeable haydite etc., and in the bottom in pond, ground, the penetration materials such as surrounding's paving one deck sandstone of infiltration well, allow the surface water can be seeped into water table fast by penetration material, and penetration material also has purifying water quality, the water of the water layer that makes to permeate the ground is purified effect; When infiltration well is dug on river (small stream) bed, the penetration material that fills up of infiltration well, as sandstone, permeable haydite etc., should be filled up to underground stream layer, touch with the sandstone of underground stream layer, and such small stream (river) water will permeate the ground water layer naturally.Rainy season the water yield many, in order to allow, the amount of surface water recurrence water table increases, speed speeds, the water yield is in the sea entered to reduce, osmos tube can be loaded in infiltration well, osmos tube surrounding fills up penetration material equally as sandstone or haydite etc., be in naturally osmotic mode at ordinary times, allow the surface water permeate the ground water layer.The osmos tube of the centre placement of infiltration well, because osmos tube is hollow, also clean water can be allowed directly to enter the bottom of well fast, can be permeated the ground water layer fast, to pick up speed again, then can use artificial pressuring method, surface water energy mat pressure is allowed to infiltrate fast in a large number, the surface water permeates the ground the result of water layer in a large number, and when infiltrating deeper subsurface water layer, deep water table rises, may just sink in stratum in unlikely continuation, when infiltrating the water table of shallow-layer, the groundwater table of shallow-layer rises, then spring in the past may will occur once again.

The ecosystem regulation structure of a kind of water described in the utility model, torrent management is on river (small stream) bed, erect retaining dykes and dams, to retain river (small stream) water (surface water) during rainy season, and flooding causes disaster when preventing heavy rain in rainy season, river (small stream) the bed gradient first should be measured before dike of building a dam, determine to build a dam according to its gradient the drop of levee spacing and each dykes and dams height again, the deposition of the annual sandstone in riverbed should be investigated simultaneously, as determining that the degree of depth of sandstone is excavated in riverbed, make the target that can reach retaining and flood control, the problem of sandstone supply can be solved simultaneously.

The ecosystem regulation structure of a kind of water described in the utility model, the retaining dykes and dams of its torrent management are different from general check dam, general check dam is tackled completely by the water of river (small stream), river, downstream (small stream) bed is caused to dry up, stream spill-over during heavy rain, do not reach the self-regulation effect that part rainwater is trapped, will inevitably come down in torrents toward downstream after the water yield spill-over that heavy rain increases totally, there is no the effect cushioned, so that cause disaster, destroy ecological, burst the dikes or bridge.Retaining dykes and dams of the present utility model, on river (small stream) bed, erect retaining dykes and dams retain river (small stream) water, the tornado when raining in upstream, fling downstream, design because of retaining dykes and dams is middle low, increase toward embankment limit with staged or ramp type gradually again, so just can according to water yield size, automatically spillway discharge is adjusted with spill-over height, when the water a large amount of when heavy rain will be dumped and enter downstream, because of low in the middle of retaining dykes and dams, again gradually with the design that staged or ramp type increase toward embankment limit, water can partly be dammed, these retaining dykes and dams are with spill-over principle design, so when water is larger, store the water yield more, the spill-over water yield also can be more, reach the balanced of automatically adjustment water retention capacity and spilling water amount, make that a large amount of rapid water yield increased is unlikely came down in torrents toward downstream in moment, so that cause disaster, at home because basin is long, flood peak is often had to occur, if there are the self-adjusting retaining dykes and dams of segmentation throttling of the present utility model to arrange, flood peak will reduce peak grease head highness, even not there will be.Retaining dykes and dams are because there being automatic overflow regulatory function, and therefore retaining dykes and dams are also without the danger of avalanche.The design of retaining dykes and dams is middle low, then increases toward embankment limit with staged or ramp type gradually, and wash away great efforts therefore, the dynamics of washing away on embankment limit is just very little, and embankment would not be washed and avalanche certainly.

The ecosystem regulation structure of a kind of water described in the utility model, the retaining dykes and dams that automatic regulating water flow amount and water retention capacity are built in torrent management, for maintaining the ecological homeostasis, organism in water is allowed to be migrated to the former habitat of upstream, the migration hole of an organism in water can be stayed below retaining dykes and dams, communicate with the river in downstream.If retaining dykes and dams are not high, the migration Kong Shangke of this biology plays a role, if retaining dykes and dams make water levels of upstream and downstream drop excessive, the hydraulic pressure in biological migration hole is excessive, current are too urgent, and organism in water just cannot adverse current be swum toward upstream, and retaining dykes and dams just become the killer of fish ecological disruption, lay eggs in fish former cache, upstream of cannot migrating, destroy original ecological homeostasis, just lose the meaning stayed and establish biological migration hole, correct retaining dykes and dams should utilize the skill of design, water ladder is built by the structure technology of retaining dykes and dams, organism in water is allowed to be able to adverse current trip above dam, this technology is exactly with the different retaining dykes and dams of multilayer height, be spaced retaining with staged and be built into water ladder, water ladder becomes mild bottom horizontal flow sheet with the current in the biological migration hole of slow landing official post, fish or other organism in water is allowed to be able to pass through retaining dykes and dams by the inverse trip in biology migration hole easily.The drop of retaining dykes and dams and the number of plies, then determine with the drop height of storage dam, when drop is large, the number of plies is just many, drop hour, the number of plies is just few, be so just unlikely to make the flow velocity of the flow in biological migration hole and pressure excessive, cause organism in water to flow upstream against the current and difficulty occurs, that thus loses this biological migration hole arranges object.The setting in biological migration hole on retaining dykes and dams, the biology migration hole of last layer retaining dykes and dams must lower than the minimum overfall of secondary one deck retaining dykes and dams, when not having a minimum overfall (as check dam and so on), is exactly its minimum overflow height, from the number of upstream, the biology migration hole of first retaining dykes and dams must be greater than the biology migration hole of second retaining dykes and dams, if had abundant water resources, when its water yield is greater than the bleeder quantity in biology migration hole of first retaining dykes and dams, will inevitably produce overflow phenomena, this overflow phenomena produces, the biology migration hole of second retaining dykes and dams is just greater than as the biology migration hole of first retaining dykes and dams, there is identical effect, now the biology migration hole of first retaining dykes and dams is just not necessarily greater than the biology migration hole of second retaining dykes and dams, no matter but below the biology migration hole of second retaining dykes and dams, have the biology migration hole of how many retaining dykes and dams, as long as the biology migration hole being not more than second retaining dykes and dams is just passable, but the perforate in the biology migration hole of every one deck retaining dykes and dams all must lower than the minimum overfall of the lower retaining dykes and dams of secondary one deck or minimum overflow height.The biology migration hole of last one deck retaining dykes and dams, the biology migration hole with communicating downstream, under downstream water plane must be arranged on, facilitate organism in water can easily by biology migration hole successively by retaining dykes and dams, in stair climbing mode by retaining dykes and dams, the inverse former habitat swimming over to upstream.

The ecosystem regulation structure of a kind of water described in the utility model, its retaining dykes and dams, the reason that organism in water can be allowed to swim over to the former cache of upstream in stair climbing mode allows water can produce ladder effect with dykes and dams structure technology, first floor retaining dykes and dams (the general check dam of retaining dykes and dams, dam) on biology migration boring ratio second layer retaining dykes and dams on biology migration hole large, and below the minimum overfall height of the biology migration Kong Yingkai of first floor retaining dykes and dams on second layer retaining dykes and dams or minimum overflow height, the water flowing through first floor retaining dykes and dams all cannot flow into the water storage space between the second layer and third layer retaining dykes and dams by the biology migration hole on second layer retaining dykes and dams, the water that cannot flow into the water storage space between the second layer and third layer retaining dykes and dams will stay water storage space between first floor and second layer retaining dykes and dams and toward going up, increase to the overfall of second layer retaining dykes and dams or minimum overflow height, the water storage space flowed between the second layer and third layer retaining dykes and dams will be overflowed.Biology migration Kong Yingkai on second layer retaining dykes and dams is below the minimum overfall or minimum overflow height of third layer retaining dykes and dams, biology migration Kong Yin on third layer retaining dykes and dams is large unlike the biology migration hole on second layer retaining dykes and dams, therefore the water flowed into by the overfall on second layer retaining dykes and dams or minimum overflow height, and the water that the biology migration hole on second layer retaining dykes and dams flows into, downstream cannot be flowed into completely.[water in downstream cannot being flowed into, water storage space between the second layer and third layer retaining dykes and dams will being accumulated in toward going up, increase to the minimum overfall of third layer retaining dykes and dams or minimum overflow height inflow downstream.Biology migration Kong Yingkai on third layer retaining dykes and dams is under the horizontal plane in downstream, by that analogy, no matter how high the drop of retaining dykes and dams have, have how many layers, all can allow organism in water as people's stair climbing, ladder swims across a ladder easily and swim go back to the former cache of upstream smoothly, if the water yield at water source is greater than the water yield by biology migration hole, when being enough to overflow, then, just need not there be the difference of size in the biology migration hole on all retaining dykes and dams.The function of dark opinion retaining dykes and dams of the present utility model, is not limited to storage dam of the present utility model, the storage dam of general debris dam or other type again, as long as have this height arrangement as the retaining dam configuration technology of ladder, organism in water just can be allowed to swim go back to upstream.Such as have three layers to illustrate with storage dam, organism in water can enter water storage space between the second layer and third layer retaining dykes and dams by downstream through the biology migration hole on third layer retaining dykes and dams, then float up, again by the biology migration hole on second layer retaining dykes and dams through the water storage space entered between first floor and second layer retaining dykes and dams, float up again, enter upstream by the biology migration hole on first floor retaining dykes and dams through first floor retaining dykes and dams, so, storage dam would not have influence on biological ecology.

The ecosystem regulation structure of a kind of water described in the utility model, its retaining dykes and dams, for maintaining normal current during dry season, the water flow of water head site during dry season should be investigated, as the foundation of biology migration hole design discharge, when discharge is very large, a plurality of biological migration hole also can be set, when biological migration hole design discharge should be less than dry season in principle, the water flow of water head site, could maintain the life and growth in nature of current during dry season like this.When the water flow of water head site is not enough, or when being consumed by use, the water stored in retaining dykes and dams will be consumed, for maintaining the life and growth in nature of current, the hole count in adjustable biological migration hole, if be only the height that single creature migration Kong Shike turns down hole, adjustable thing migration hole size of being born simultaneously, to reduce the flow of water, there is sufficient water source in order to regulate during dry season, make small stream (river) bed unlikely dry.

The ecosystem regulation structure of a kind of water described in the utility model, erect retaining dykes and dams on river (small stream) bed, to retain river (small stream) water during rainy season, river (small stream) water is by inflow downstream, biology migration hole at ordinary times, when the water yield is many, then naturally fill up the water yield that dry season surpasses, after filling up, just automatic spill-over flows into downstream by minimum overfall, the tornado when raining in upstream, water level increases, then part sequentially flows into downstream by overfall height, part is retained in storage dam by retaining dykes and dams, with regard to not reason heavy rain and the rainwater exploded make tornado fling downstream and cause disaster, if sectionalized regulation can be flowed with regard to whole piece small stream (river), just there is no the crisis of lack of water, and the danger that tornado is inrushed, also the protection of certain degree can be obtained to ecology, there is flood control results again, and multinomial resource resources profit can be increased.

The ecosystem regulation structure of a kind of water described in the utility model; retaining dykes and dams erected by river (small stream) bed; to retain river (small stream) water; the tornado when raining in upstream; because storage dam has multilayer retaining dykes and dams with the flow velocity of moderate water; and have multilayer retaining dykes and dams stop and protect organism in water, to be unlikelyly swept away by the torrent, to safeguard normal ecological.

The ecosystem regulation structure of a kind of water described in the utility model, is erect retaining dykes and dams on river (small stream) bed, to retain river (small stream) water, makes riverbed be unlikely to dry up when dry season and endanger breeding and the existence of organism in water.

The ecosystem regulation structure of a kind of water described in the utility model erects retaining dykes and dams on river (small stream) bed, to retain river (small stream) water, also can be appropriate as purposes such as cultivating, fish, have a rest, and beautify the environment simultaneously.

The ecosystem regulation structure of a kind of water described in the utility model; erect retaining dykes and dams on river (small stream) bed; to retain river (small stream) water; if this project is constructed in the bridge pier upstream and downstream of bridge, storage dam have protection bridge pier do not washed away by river and exposed sink, rock stratum planted deeply by bridge pier; there is again the effect of strengthening retaining dykes and dams; complement each other, bridge security is safeguarded, can obtain sandstone according to the riverbed degree of depth of design and unlikelyly jeopardize bridge pier again.

The ecosystem regulation structure of a kind of water described in the utility model, another technology that its streams (river course) is renovated is sinking shaft on small stream (river) bed, because there are many underground water active layer on stratum, the water of underground water active layer is after leaning on the rain penetration stratum on earth's surface and tree root tree branches when rainy to inhale full moisture, disengage from tree root, because ground surface environment is destroyed, the woods are cut down, earth's surface impervious layer increases, add the unconfined extraction of the mankind, groundwater table is caused to decline, peter out in water source, fault sag, the spring be in the past found everywhere is shown in no longer again, current mankind's science and technology is flourishing, for asking development in science and technology and comfortable life, water requirement is anxious to be increased, then destroy and be further intensified, ecological great calamity will be caused, develop into human catastrophe, nearest unusual weather conditions, as there is the world of ice and snow in 49 states in National 50 state, the floods etc. of Australia province of Queensland, natural disaster keeps pouring in, this is the result of ecological disruption, therefore countermeasure must be thought as early as possible, avoid ecological great calamity, natural disaster is not allowed to continue again and again to occur, there are enough water resources again, unique method is exactly by the water resource reservation of surplus in rainy season, it is not allowed to run quickly fast into sea, do not overflow, allow well human use and ecodevelopment, and prevent fault sag.So the ecosystem regulation structure of a kind of water described in the utility model erects retaining dykes and dams on river (small stream) bed, to retain river (small stream) water, storage rainwater, during for arid, infiltration well can be cut a hole again on riverbed, utilize the sandstone of underground stream layer as filtering material, small stream (river) water making rainy season clean can return the water layer that permeates the ground in a large number, when abundant water in rainy season, when wanting have more substantial water to be stored in water table, also Manual pressurizing mode can be used, by means of pressure, more substantial water can be permeated the ground fast water layer, to prevent fault sag, appropriateness use can be extracted again when lack of water, fault sag is caused with regard to not being afraid of excessive extraction, so just can supplement water supply during arid, solve the problem of insufficient water sources.

Detailed description of the invention

Below in conjunction with drawings and Examples, structure of the present utility model is described in detail:

As Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Fig. 5, the ecosystem regulation structure of a kind of water described in the utility model, for the method for water resource retaining surplus in summer be low-lying have on the surface water 1 place or small stream (river) bed build retaining dykes and dams, to store the surface water, a plurality of infiltration well 2 is cut a hole there being the surface water 1 place, go deep into each water table 3, fill up as the penetration material such as sandstone or permeable haydite 4 in infiltration well, the surface water 1 is connected with water table 3, the surface water 1 enters water table 3 by penetration material 4 filtration and infiltration in infiltration well 2, the surface water after raining is stored in water table, groundwater table can be allowed like this to raise, prevent fault sag, also appropriateness use can be extracted when dry season lack of water.Infiltration well in retaining dykes and dams also can connect the water source of various separate sources, rainwater as clean in roof or spring etc., equally can reach identical effect, during rainy season, rainwater becomes large number of ground water again, for making surface water energy mass storage in water table, osmos tube 5 can be put in infiltration well, osmos tube 5 is same with between the borehole wall 6 permeating well 2 to be filled up as sandstone, the penetration materials such as permeable haydite 4, usually be in naturally osmotic mode, the surface water 1 is allowed to permeate the ground water layer 3 through penetration material 4 in naturally osmotic mode, if when the surface water is clean, also osmos tube 5 can directly be entered, by bottom directly through penetration material 4, the water layer 3 that permeates the ground fast stores, to more rapid, high volume, the surface water 1 water layer 3 that permeates the ground is stored, by Manual pressurizing mode by the surface water through osmos tube 5, osmos tube is provided with permeable hole 10, directly again to be permeated the ground water layer 3 through penetration material 4 by its bottom high-pressure.

The ecosystem regulation structure of a kind of water described in the utility model, when the infiltration well 2 excavated on small stream bed in its embodiment gos deep into water table 3, as shown in Figure 2, with the sand stone layer of the very thick underground stream layer 7 of one deck on small stream bed, very abundant current are had in sand stone layer with underground stream layer 7, the underflow water be commonly called as exactly, this underflow water is clean water source the most, is the best approach using this underflow water as the water source of the water layer that permeates the ground.So the penetration material 4 of infiltration well should fill up the sand stone layer close contact with underground stream layer 7, the water of underground stream layer 7 also can be made to infiltrate osmos tube 5 and to enter water table 3 fast.At ordinary times, small stream (river) water allows the water naturally osmotic in underground stream layer 7 enter water table 3 by the penetration material 4 such as surrounding's sandstone of osmos tube 5, the sandstone that underflow water is through underground stream layer filters, so permeate the ground, the water of water layer is clean water, and rainy season, water was many, then can not rain, when stream clarification is clean, utilize Manual pressurizing, to permeate the ground water layer to accelerate stream, the osmos tube 5 of small stream (river) water through permeating well 2 is penetrated into the aquifer storage of each underground.If desired in the scope in its distributed area, also can extract use, during extraction, note amount of seepage and water level, also just be unlikely to the problem having groundwater table decline or fault sag.

The ecosystem regulation structure of a kind of water described in the utility model, on small stream (river) bed, retaining dykes and dams are constructed with bridge place in its embodiment, as Fig. 3, Fig. 4 and Figure 5 shows that three ply formula retaining dykes and dams 8, horizontal plane 9 is had at the downstream water surface of retaining dykes and dams, retaining dykes and dams 8 have first floor retaining dykes and dams 8-1, second layer retaining dykes and dams 8-2, third layer retaining dykes and dams 8-3, it forms with height such as the trapezoidal structure that is spaced, in order to store the surface water, and make water form shape as trapezoidal, allow organism in water energy adverse current swim across retaining dykes and dams and enter upstream, to remain ecological, the first floor being counted retaining dykes and dams 8 by upstream is called first floor retaining dykes and dams 8-1, and the second layer is called second layer retaining dykes and dams 8-2, and third layer is called third layer retaining dykes and dams 8-3.First floor retaining dykes and dams 8-1 has the biological migration hole 8-1-1(of first floor to see Fig. 4), second layer retaining dykes and dams 8-2 has the biological migration hole 8-2-1(figure of the second layer not draw, its structure and Fig. 4 similar), third layer retaining dykes and dams 8-3 has the biological migration hole 8-3-1(figure of third layer not draw, its structure and Fig. 4 similar).The biological migration hole 8-1-1 of first floor must be greater than the biological migration hole 8-2-1 of the second layer, if when water source current are greater than the bleeder quantity of first floor biological migration hole 8-1-1, the biological migration hole 8-1-1 of first floor is just not necessarily greater than the biological migration hole 8-2-1 of the second layer.The biological migration hole 8-3-1 of third layer can not be greater than the biological migration hole 8-2-1 of the second layer, no matter has how many biological migration holes again, as long as the biological migration hole 8-2-1 of the second layer being not more than second layer retaining dykes and dams 8-2 is just passable.When dry season, the water yield at water source is greater than the water yield by the biological migration hole 8-1-1 of first floor, water must be had to accumulate and in retaining dykes and dams 8, water level is gone up.When the water level in retaining dykes and dams 8 go up exceed the first floor of first floor retaining dykes and dams 8-1 minimum overfall 8-1-2 time, natural overflow will flow into water storage space between first floor retaining dykes and dams 8-1 and second layer retaining dykes and dams 8-2, by the biological migration hole 8-1-1 of first floor by the water after first floor retaining dykes and dams 8-1, enter the water storage space between first floor retaining dykes and dams 8-1 and second layer retaining dykes and dams 8-2, because the biological migration hole 8-2-1 of the second layer is less than first floor biological migration hole 8-1-1, just cannot completely the water by the biological migration hole 8-1-1 of first floor all be released by the biological migration hole 8-2-1 of the second layer, then and by the water of first floor minimum overfall 8-1-2 overflow will do not accumulated the water storage space between first floor retaining dykes and dams 8-1 and second layer retaining dykes and dams 8-2 by the water released, water level is gone up gradually.When water level increases to the minimum overfall 8-2-2 of the second layer higher than second layer retaining dykes and dams 8-2, water natural overflow will enter water storage space between second layer retaining dykes and dams 8-2 and third layer retaining dykes and dams 8-3, because the biological migration hole 8-3-1 of third layer is not more than again the biological migration hole 8-2-1 of the second layer, the biological migration hole 8-3-1 of third layer just all cannot release by the biological migration hole 8-2-1 of the second layer and from the water that the minimum overfall 8-2-2 of the second layer flows into, will accumulate in the water storage space between second layer retaining dykes and dams 8-2 and third layer retaining dykes and dams 8-3, the water level of the water storage space between second layer retaining dykes and dams 8-2 and third layer retaining dykes and dams 8-3 can not made equally to go up gradually by the water released, when increasing to the minimum overfall 8-3-2 of the third layer higher than third layer retaining dykes and dams 8-3, water will enter on the riverbed in downstream from third layer minimum overfall 8-3-2 overflow.Certainly larger than the second layer biological migration hole 8-2-1 at the biological migration hole 8-1-1 of the first floor counted from upstream, as long as biological migration hole 8-2-1 is large unlike the biological migration hole of front one deck, the second layer, just can there is this effect equally in biological migration hole 8-3-1 (no matter several) of third layer.The height of the biological migration hole 8-1-1 of first floor must lower than the minimum overfall 8-2-2 of the second layer of second layer retaining dykes and dams 8-2, the height of the biological migration hole 8-2-1 of the second layer must lower than the minimum overfall 8-3-2 of third layer retaining dykes and dams 8-3, and the height of the biological migration hole 8-3-1 of third layer must lower than the horizontal plane 9 in retaining dykes and dams downstream.Like this, organism in water just can pass third layer retaining dykes and dams 8-3 by the biological migration hole 8-3-1 of third layer easily, enter the water storage space between second layer retaining dykes and dams 8-2 and third layer retaining dykes and dams 8-3, then up float, second layer retaining dykes and dams 8-2 is passed again by the biological migration hole 8-2-1 of the second layer, enter the water storage space between second layer retaining dykes and dams 8-2 and first floor retaining dykes and dams 8-1, then up float again, first floor retaining dykes and dams 8-1 is passed again by the biological migration hole 8-1-1 of first floor, enter upstream, no matter retaining dykes and dams have how many layers, organism in water all mode can swim go back to upstream from downstream adverse current according to this.

First floor retaining dykes and dams 8-1 described in the utility model has the biological migration hole 8-1-1 of first floor, the design of this first floor biological migration hole 8-1-1 openings of sizes, the water yield at water source when must make to be less than dry season by the water yield of first floor biological migration hole 8-1-1 opening, the water of river (small stream) bed so just can be made unlikely dry, during some seasons, the water yield at water source is too small or do not have, just must use the water storage in retaining dykes and dams, the now biological migration hole 8-1-1 of first floor, the biological migration hole 8-2-1 of the second layer, the biology migration hole of the biological migration hole 8-3-1 of third layer etc. will down adjust, and reduce bleeder quantity, ecological to maintain river (small stream) bed.

As shown in Figure 5; for a kind of setting position schematic diagram of retaining dykes and dams and bridge pier; retaining dykes and dams have been built between bridge pier 11; retaining dykes and dams have protection bridge pier do not washed away by river and exposed sink; bridge pier plants rock stratum deeply, has again the effect of strengthening retaining dykes and dams, complements each other; bridge security is safeguarded, can obtain sandstone according to the riverbed degree of depth of design and unlikelyly jeopardize bridge pier again.

Above-mentioned retaining dykes and dams structure of the present utility model is not only applicable to retaining dykes and dams of the present utility model; the retaining dykes and dams of other any pattern; as check dam, dam etc. the structure of retaining dykes and dams of the present utility model all can be set; because of in many styles; cannot repeat one by one; therefore there is the same person of Structure type with retaining dykes and dams of the present utility model, all belong to the protection domain of the utility model.
