Abstract
The utility model provides a butyl dam structure, including the spur dike body, the spur dike body is establish in the river, and the head -end of spur dike body extends to the ordinary water level line outside in river, low reaches end position in the river middle part of spur dike body, it is regional that the first rivers passageway of one side for supplying continuous rivers to pass through of spur dike body, the opposite side of spur dike body be the pool, the spur dike body be close to the head -end and position that be located the bank line on be equipped with the mill weir, cross mill weir formation second rivers passageway between pool region and first rivers passageway. The utility model provides an under the circumstances that keeps the pool environment as far as possible, satisfy the contradiction of drift gamogenetic egg fish roe drift condition again simultaneously, kept the pool in the river course, unhurried current habitat, keep the habitat diversification of habitat protection section, set up the mill weir, keep in the pool connectivity in water exchange and habitat.
Description
Technical field
The utility model relates to Hydraulic and Hydro-Power Engineering field, particularly relates to the structure of groynes structure.
Background technology
Some produce Drifting egg fish, and embryonated egg needs could hatch after drifting about in the continuous flowing water section of sufficient length; When flow velocity in river course be less than fish-egg rise drift about speed time, fish-egg can sink and dead.Along with the construction of China's Hydraulic and Hydro-Power Engineering, pool region in river increases, section, flowing water habitat is subject to continuous compression, because pool flow velocity is often less, can not meet the requirement of Drifting egg fish fish-egg drift required flow rate, the existence of producing Drifting egg fish is subject to further threat, therefore, how while meeting Drifting egg fish fish-egg drift flow velocity, retaining pool environment is as far as possible the difficult problem faced at present.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of groynes structure, can build various hydrophytic habitat in common flowing water environment.
The technical scheme that the utility model technical solution problem adopts is: a kind of novel groynes structure, comprise groynes body, described groynes ontology construct is in river, the upstream extremity of described groynes body extends to outside the normal water line in described river, the downstream of described groynes body is positioned at described midchannel, the side of described groynes body is the first water stream channel passed through for solid stream of water, the opposite side of described groynes body is pool region, described groynes body near upstream extremity and the position being positioned at bank line was provided with mill weir, described mill weir of crossing forms the second water stream channel between pool region and the first water stream channel.
While employing technique scheme, the utility model can also adopt or combine and adopt following further technical scheme:
Described groynes body is overflow dam, the elevation of its dam crest higher than ordinary water level, lower than flood season level.
Described first water stream channel and described pool region are collected in the downstream of described groynes body.
Described groynes body is cyclopean dam or concrete dam.
The beneficial effects of the utility model are: the utility model solves when retaining pool environment as far as possible; meet the contradiction of Drifting egg fish fish-egg drift condition again simultaneously; can provide continuous stream aquatic border for protection section, habitat; meet the condition of producing Drifting egg fish fish-egg and drifting about; for it provides the primary condition of the history of life; while meeting flowing water habitat; remain the pool in river course, unhurried current habitat; keep the habitat diversification of protection section, habitat; mill weir was set, kept the connectedness in water body exchange and habitat in pool.Structure of the present utility model can be widely used in the structure of modification in the region such as river course, current, to suffering that the habitat that artificial engineering destroys has great repair.

Fig. 1 is overall structure top view of the present utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is the B-B sectional view of Fig. 1.
Detailed description of the invention
With reference to accompanying drawing.
The utility model comprises groynes body 1, groynes body 1 is based upon in river 2, groynes body 1 be on the whole Parallel to the flow direction build, in the present embodiment, groynes body 1 adopts cyclopean to pile the groynes of form, arranges deal pile to strengthen the stability of cyclopean heap bottom riverbed.The upstream extremity 3 of groynes body 1 extends to outside the normal water line 7 in river, play the effect stopping current, the downstream 4 of groynes body 1 is positioned at midchannel, the side of groynes body 1 forms the first water stream channel 5 passed through for solid stream of water, first water stream channel 5 can provide the primary condition of existence for drifting egg fish, the opposite side of groynes body 1 is pool region 6, groynes body 1 near upstream extremity 3 position being positioned at normal water line 7 had been provided with mill weir 8, cross mill weir 8 and form the second water stream channel 9 between pool region 6 and the first water stream channel 5, the water body in pool is kept to exchange, and ensure the connectedness of itself and upper river.First water stream channel 5 and pool region 6 are collected at downstream 4 place of groynes body 1.
Groynes body 1 is overflow dam, and its crest elevation, higher than field water level, lower than flood season level, when water level is higher in flood season river course, can cross water from dam crest, ensures that the construction of groynes does not affect river course flood requirement.
In figure, the direction of arrow is water (flow) direction, and label 10 is bank form line.
Claims (4)
1. a novel groynes structure, comprise groynes body, it is characterized in that: described groynes ontology construct is in river, the upstream extremity of described groynes body extends to outside the normal water line in described river, the downstream of described groynes body is positioned at described midchannel, the side of described groynes body is the first water stream channel passed through for solid stream of water, the opposite side of described groynes body is pool region, described groynes body near upstream extremity and the position being positioned at normal water line was provided with mill weir, described mill weir of crossing forms the second water stream channel between pool region and the first water stream channel.
