Abstract
The utility model provides a kind of attracting groynes, including groynes and fish pass entrance；The groynes and fish pass entrance are arranged at the both sides on riverbank, and groynes has multiple, and fish pass entrance is arranged on the lower section of end groynes；The dam heart of the groynes is equipped with reinforced-concrete, and the both sides dam slope of groynes is set to ladder；Plastic bottle is equipped in the ladder, soil and plant are equipped in plastic bottle.The utility model can improve flow condition with stable bank slope, and the planting plants in fish nido ladder dam slope form graceful landscape so that entire design structure is stable, simple, and practicability is stronger.
Description
Technical field
The utility model is related to a kind of attracting groynes, belong to ecological water conservancy project structure technical field in hydroelectric project.
Background technology
In recent years, the theory of ecological, environmental protective is introduced into groynes design by many researchers, the ecological, environmental protective function of groynes
It is mentioned higher status.
Such as Chinese patent " ecological percolating type water purification groin system (publication number：CN101973638A, publication date：
2011.2.16 groynes system disclosed in) ", there is provided biological reinforced region, block stone body, steel wire cobble body, submerged plant and kinds
The structures such as bag, blotter, cobble filtrate body are planted, there is preferable purification of water quality and improve quality of water environment, still
Complicated, construction and maintenance cost are higher.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of attracting groynes, the attracting groynes is with reinforcement coagulation
Soil is the groynes dam heart, using fish nido ladder as dam slope, arranges that different water plants build artificial fish nests according to water level, and by fourth
Dam is designed as double cluster formula structures, and the effect slowed down is played to transverse direction and longitudinal direction torrent.
The utility model is achieved by the following technical programs.
A kind of attracting groynes provided by the utility model, including groynes and fish pass entrance；The groynes and fish pass entrance are equal
It is arranged on the both sides on riverbank, groynes has multiple, and fish pass entrance is arranged on the lower section of end groynes；The dam heart of the groynes, which is equipped with, to be added
Reinforced concrete, the both sides dam slope of groynes are set to ladder；Plastic bottle is equipped in the ladder, soil and plant are equipped in plastic bottle.
The groynes is double cluster formula groynes structures.
The ladder is fish nido ladder.
The ladder is made of wire mesh cage, iron wire and stone, and stone is put into wire mesh cage, and wire mesh cage is fixed simultaneously by iron wire
It is close-coupled on dam slope.
The internal diameter of the stone is 1m, has filled gravel and soil between stone gap, the grain size of gravel for 5~
10cm。
The crest elevation of the groynes is between average of normal water-levels and average flood position.
Kind submerged plant is implanted in plastic bottle below water level line, kind has floating leaf in the plastic bottle of water level line fluctuation zone
Plant, kind of emergent aquactic plant in the plastic bottle more than water level line.
The beneficial effects of the utility model are：
1. groynes monomer is double cluster formula structures, has for transverse direction and longitudinal direction current and preferably slow down effect, optimize under fish pass
It swims domain part water body fluidised form, is provided for fish and good have a rest, hide enemy space；
2. groynes dam slope adheres to the design concept of close natural water, ratchel is fixed with wire mesh cage and constructs ladder dam slope,
Planting aquatic plants in the matrix environment of gravel and soil are filled, further provide good egg-laying environment for fish；
3. arranging double cluster formula groynes different in size on the longitudinal direction of riverbank, diversified fish habitat space is built, induces fish
Class progressively adapts to fish pass import downstream water environment, finally and successfully to find fish pass import realization uplink；
4. can improve flow condition with stable bank slope, the planting plants in fish nido ladder dam slope form graceful landscape,
So that entire design structure is stable, simple, practicability is stronger.

Specific embodiment
Be described further below the technical solution of the utility model, but claimed scope be not limited to it is described.
As depicted in figs. 1 and 2, a kind of attracting groynes, including groynes 1 and fish pass entrance 2；The groynes 1 and fish pass entrance 2
It is arranged at the both sides on riverbank, groynes 1 has multiple, and fish pass entrance 2 is arranged on the lower section of end groynes 1；The dam heart of the groynes 1
Equipped with reinforced-concrete 3, the both sides dam slope of groynes 1 is set to ladder 4；Plastic bottle 8 is equipped in the ladder 4, is equipped in plastic bottle 8
Soil 9 and plant.
The groynes 1 is double cluster formula groynes structures, groynes 1 it is different in size.
The ladder 4 is fish nido ladder.
The ladder 4 is made of wire mesh cage 10, iron wire 11 and stone, and stone is put into wire mesh cage 10, and wire mesh cage 10 passes through
Iron wire 11 is fixed and is close-coupled on dam slope, as shown in Figure 3.
The internal diameter of the stone is 1m, has filled gravel and soil 9 between stone gap, the grain size of gravel for 5~
10cm。
For the crest elevation of the groynes 1 between average of normal water-levels and average flood position, when flood period, can be used as shallow water
Groynes 1 will not excessively hinder current, avoid abutment is too deep from washing away.
According to fish nido ladder 4 and water level relative position relation, different plants are planted in rank 4, below water level line
Interior kind of plastic bottle 8 is implanted with submerged plant 7, and interior kind of the plastic bottle 8 in water level line fluctuation zone has floatingleaved plant 6, more than water level line
Plastic bottle 8 in kind of emergent aquactic plant 5, as shown in Figure 4.
