Description
Technical field
The present invention relates to a kind of groynes, be specifically related to a kind of ecological groynes of water conservancy diversion of new construction.
Background technology
Groynes is also referred to as the T-shaped dam, is the most frequently used a kind of in dredging waterway and the waterway regulation building, is the dam shape building that an end links to each other with the riverbank, the other end stretches to the riverbed, connects into T-shaped with the riverbank in the plane.In river engineering, groynes is avoided washing away with the protection riverbank by choosing stream, water conservancy diversion; In waterway regulation works, the then narrow riverbed of transmitted beam, clearing sands with converging flow and to satisfy boat dark.The kind of groynes is a lot, by the flat shape classification linear, eave tile shape and T-shaped etc. is arranged.With regard to the material of constructing groynes, the most frequently used in the training works is piece stone class groynes, comprises concrete groynes, iron wire gabion groynes, jackstone groynes and combined type groynes etc.
Groynes dam body physical dimension generally meets following requirement: (1) dam body structure: piece stone groynes trapezoidal transverse face, the desirable 1:1 to 1:1.5 of upstream batter, the desirable 1:1 to 1:2.5:(2 of downstream slope) dam crest longitudinal gradient: the wide b of dam crest desirable 1 is to 4m, the regional desirable value bigger than normal that flow velocity is big; Dam crest should be smooth, the desirable 1:100 to 1:300(3 of longitudinal gradient) the abutment structure: the dam crest in abutment 10 to the 20m scopes can suitably be widened, and is smooth curve on the abutment plane, and it should be taken as 1:2.5 to 1:3 to the slope, river.The dam length L of groynes and height of dam H are decided by the regulation line width and the regulated water stage of concrete section respectively, and usually dam length is tens meters and does not wait to hundreds of rice, and height of dam is several meters not to be waited to tens meters.Figure (1) has provided conventional groynes plane and elevation.
After the river course is provided with groynes, the riverbed constriction, the discharge area reduces, and flow velocity strengthens, and towards dark original bed surface, thereby reaches waterway regulation works " clearing sands with converging flow " effect.Major trough is towards dark the time, near abutment, current are squeezed, walking around under the current of groynes and the groynes fluoran stream surface undercurrent interacts and forms a succession of vortex at bed surface, also formed simultaneously strong turbulent flow band, cause abutment downstream local scour (see figure 2), can reach tens of rice, jeopardize the stable of dam body towards dark maximum.The ecological investigation in the Xijiang River is shown carrying out of Xijiang River waterway regulation works reduced the habitat conditions quality even made original biological habitat lose, and can the existence of zoobenthos be had a negative impact thus; Moving of Zhou Tan position also forces the original place of laying eggs of fish destroyed.Therefore, when the satisfied boat of groynes clearing sands with converging flow is dark, has also destroyed and coerced river ecosystem, the formation of abutment scour hole is stablized the new problem of having brought to dam body.
Summary of the invention
Habitat conditions quality that purpose of the present invention has been the reduction that exists at conventional groynes, destroy problem such as fish spawning ground, provide a kind of novel water conservancy diversion ecological groynes.The ecological groynes of this novel water conservancy diversion helps adhering to of various aquatic organisms and survives, and helps playing with water and looking for food of fish.Can satisfy multiple biological nature demand.Prioritization scheme can also provide biology to hide the space of macro-organism predation.
The scheme of finishing the foregoing invention task is, the ecological groynes of a kind of water conservancy diversion, the ecological groynes of this water conservancy diversion is the dam shape building that an end links to each other with the riverbank, the other end stretches to the riverbed, connect into T-shaped with the riverbank in the plane, it is characterized in that, periphery at the ecological groynes dam body of this water conservancy diversion underwater portion is provided with the several layers deflector, to regulate groynes periphery water flow structure, described deflector is a kind of rigid slab, one side of this deflector is fixed on the groynes dam body, and the side of two sides vertical with this fixed edge and other deflectors of its both sides is connected to each other.
The present invention recommends, and the described several layers deflector that is provided with is that two-layer deflector is set, and this two-layer deflector is separately positioned on 1/3 place of height of dam and 2/3 place of height of dam.Referring to Fig. 3.
The above constitutes the rigid slab of deflector, and material can be steel plate, non-ferrous metal board, bamboo plank or plastic plate; It can also be concrete slab.
Be consistent at the bottom of the magnitude range of described deflector and the dam.The ecological groynes of water conservancy diversion of the present invention is compared with the conventional groynes of prior art has (1) ecological effect; (2) high stability; (3) same renovating effect.
Exist tangible unhurried current zone between each deflector around the ecological groynes of water conservancy diversion, help adhering to and surviving of various aquatic organisms, regional high flow rate and low flow velocity are interspersed about the deflector, help playing with water and looking for food of fish.Simultaneously each deflector exists the height turbulence intensity phenomenon that is interspersed in the zone up and down, and low turbulent fluctuation zone helps that aquatic organism stops and absorption, and strong turbulent fluctuation band offers the fish space of playing with water again.No matter vertically turbulence intensity still is that horizontal, vertical turbulence intensity all exists strong and weak conversion waters, can satisfy multiple biological nature demand.Between ecological groynes two dividing plates of water conservancy diversion or the cavity between dividing plate and the dam body can provide biology to hide the space of macro-organism predation.
The ecological effect of the ecological groynes of water conservancy diversion is mainly reflected in following three aspects: various stream effect, protection effect and bait effect.These three kinds of effects connect each other, supplement and complement each other, various stream makes various planktonic organisms and zoobenthos become bait in this delay, provide fish to play and to look for food the place, the enemy can be kept away for meiofaunas such as juvenile fish in the protection space that ecological groynes water-permeable frame forms, become good small habitat, ecological effect is obvious.
Deflector set up the flow-disturbing that has weakened abutment, and blocked undercurrent under the abutment, and to compare with the conventional groynes of prior art, the favourable opposition of the ecological head of groyne of water conservancy diversion is dark, the scour hole scope all reduces to some extent, and scour hole has the trend that moves away from the abutment direction towards downstream, all helps the stable of dam body.
The ecologic structure deflector has been adjusted the partial water flow structure around the dam body, and major trough district current are not had influence substantially, and the general scour in major trough district changes little, and the waterway regulation effect is consistent with conventional groynes.
