Description
Technical field
The utility model relates to the waterway regulation structure of water conservancy water transport technical field, especially a kind of local overcurrent is environmental
Groynes.
Background technique
China has a vast territory, and rivers gather.In controlling river and water transportation construction project, groynes is inevitably used
Structure.In river engineering, groynes is one of most widely used building；It in flood control works, can be used for that riverbank is protected to exempt from
It is washed away；In waterway regulation works, it can be used for the narrow riverbed of beam, scouring depth navigation channel, i.e. " clearing sands with converging flow "；In river shoal project of cultivation
In, build groynes (group) first usually to promote to become silted up.
Groynes design only was carried out from hydrodynamics and the angle of structural mechanics in the past, few combination ecology and aquatic
Biological need end carries out the design of groynes structure.Under normal circumstances, silt can deposit behind dam forms dam field, is that fish etc. are aquatic
The good habitat of biology, but often maximized in traditional groynes structured design process in order to seek project benefit, often by groynes
It is designed as continuous, fluid-tight solid groin, on the one hand, ignore that there are inhabit asking for habitat and migration channel for aquatile
Topic, Plants and Animals are difficult to grow at groynes and inhabit, and are difficult to form the unified organic ecosphere with dam field thereafter, are unfavorable for fourth
The maintenance in habitat around dam, in addition, water flow structure is more complicated at groynes, since area of passage is smaller, so that disconnected where groynes
Surface current speed is larger, water flow for a long time wash away under, dam body surface layer block stone easily slides, and causes local buckling, and plant is also difficult to adhere to.
Therefore, there is an urgent need to develop a kind of parts can cross water, environmentally protective, the groynes of hydrophilic close friend in ecology on material
Structure, it is desirable that it can either reduce washing away for river, guarantee the stabilization of dam body, meet the needs of navigation, and can seek for animals and plants
Make good habitat.
Summary of the invention
The utility model is to solve technical problem present in well-known technique and provide a kind of local overcurrent ecotype groynes,
Structure used by the groynes can reduce the local scour at abutment and dam root position, improve floodwater capacity, be conducive to dam field
Siltation forms shoal, is that the rivers biologies such as fish build good habitat.
The utility model is adopted the technical scheme that solve technical problem present in well-known technique: a kind of part mistake
Environmental groynes is flowed, the dam body including bed course and building on it is equipped with an overflow gap at the middle part of the dam body.
The dam body is that stone, the lattice guest are filled in the lattice guest gabion made of lattice guest's gabion code is built
Connection is bound between gabion.
The stone loaded in lattice guest's gabion of part below the overflow gap two sides side slope ordinary water level is fish nest brick.
Alloy steel cage gauze pad I is covered on the bottom surface of the overflow gap, the alloy steel cage gauze pad I is built-in
It is natural pebble.
The bed course is made of the natural material making with water penetration.
It is covered with alloy steel cage gauze pad II in the two sides side slope of the overflow gap for being located at ordinary water level or more, it is described
The lower part of alloy steel cage gauze pad II is quarry bed, and top is ecological pad II, and the ecological pad II is paved by ecology bag II
, soil and vegetable seeds rich in organic matter are provided in the ecology bag II.
It is covered with alloy steel cage gauze pad III in dam crest and abutment surface, the lower part of the alloy steel cage gauze pad III is day
Right rock layers, top are ecological pad I, and the ecological pad I is paved by ecology bag I, is provided in the ecology bag I rich in organic
The soil and vegetable seeds of matter.
The ecology bag I is made of being woven as natural plant material.
The ecology bag II is made of being woven as natural plant material.
Abutment arc slope surface made of being filled as riprap.
The utility model has the advantages and positive effects of:
1. the dam field behind dam body notch and dam can form the metastable space of fluidised form, it is alternate with pool to form shoal
Diversity fluidised form can provide suitable habitat for fish and benthon.It, can be with 2. dam body is built using lattice guest gabion code
The dosage of building stones is reduced, investment is reduced；Mud in lattice guest's gabion in cage between stone gap is conducive to plant growth.3. groynes dam
Body locally crosses water, on the one hand in middle dry season, groynes converging flow into main channel, scouring depth navigation channel；It is worn in flood period a part of water flow from dam body
It crosses, improves floodwater capacity, on the other hand dispersed washing away around dam for water flow, in addition slowed down the flow velocity of dam water flow, thus
The local scour for reducing abutment and dam root is conducive to the siltation of dam field, forms shoal.In conclusion the utility model can rush
Shenzhen Airlines' slot safeguards dimensions of the channel, and can improve fluidised form, reduces dam body and washes away to water flow, while can improve again raw around dam body
State environment is that the rivers biologies such as fish build good habitat, meets engineering construction and protects the needs of environment.
