Description
Technical field
The utility model relates to the waterway regulation structure of water conservancy water transport technical field, in particular to a kind of anti-impact ecotype fourth
Dam.
Background technique
China has a vast territory, and rivers gather.Groynes is inevitably used in controlling river and water transportation construction project
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, and " clearing sands with converging flow "；In river shoal project of cultivation
In, build groynes (group) first usually to promote to become silted up.For traditional groynes structure, under long-term current scour, surface layer block stone is sliding
It falls, dam body erosion is serious, especially abutment and dam root position, and since flow velocity is very fast at this, basis is easy to be destroyed by rush of water, and leads to part
Unstability loses regulation function.In addition under groynes clearing sands with converging flow effect, silt can back-silt to form dam field behind dam, herein fluidised form
Relatively slow, it is the good habitat that aquatile inhabites that the depth of water is shallower, but in traditional groynes design, it is aquatic for often ignoring
Biology inhabites construction and inhabites space, and Plants and Animals is difficult to grow at groynes and inhabit.Therefore, there is an urgent need to develop a kind of protections
Dam body slows down destruction of the water flow to dam body, and stability is good, and the novel groynes knot in good habitat can be built for periphery aquatile
Structure.
Summary of the invention
The utility model is to solve technical problem present in well-known technique and provide a kind of anti-impact ecotype groynes, the fourth
Dam can reduce water flow and wash away to dam body, build good habitat for periphery aquatile.
The utility model is adopted the technical scheme that solve technical problem present in well-known technique: a kind of anti-impact is raw
State type groynes is fixed with anti-including building dam body and abutment on bed course in the surface side that meets water of the dam body and the abutment
Steel plate is rushed, is equipped on the dam body multiple positioned at design water level hole below.
The top mark height of the anti-impact steel plate is higher than regulated water stage, is lower than dam crest, and riverbed is inserted into the bottom of the anti-impact steel plate
Following certain depth.
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.
Interval is equipped between the dam body and riverbank.
The bed course is made of the natural material making with water penetration.
It is covered with alloy steel cage gauze pad in dam crest and abutment surface, the lower part of the alloy steel cage gauze pad is natural stone
Layer, top is ecological pad, and the ecological pad is paved by ecology bag, is provided with the soil rich in organic matter in the ecology bag
And vegetable seeds.
The ecology bag is made of being woven as natural plant material.
Abutment arc slope surface made of being filled as riprap.
The width at the interval is 3~10m.
The utility model has the advantages and positive effects of:
1. anti-impact steel plate can reduce water flow directly washing away to dam body, safeguards dam stabilization, be conducive to the operation in navigation channel
With maintenance.
2. the mud between stone gap in lattice guest's gabion is conducive to plant growth.
3. the hole on dam body is capable of forming the metastable space of fluidised form, it is suitable to provide for fish and benthon
Habitat.
4. dam body is built using lattice guest gabion code, the dosage of building stones can be reduced, a large amount of construction investments can be saved, especially used
Expect more, the biggish river of the depth of water, benefit is especially pronounced.
Dam body is washed away in conclusion the utility model can reduce water flow, improves dam stability, while can change again
Ecological environment around kind dam body, is that the rivers biologies such as fish build good habitat, provides growth attachment condition for plant, meets work
The needs of Cheng Jianshe and protection environment.
Detailed description of the invention
Fig. 1 is profilograph of the utility model along the axis of dam；
Fig. 2 is the top view of the utility model；
Fig. 3 is the drawing in side sectional elevation at the utility model hole.In figure: 1, lattice guest gabion, 2, riprap, 3, alloy-steel wire

Specific embodiment
For the invention, features and effects that can further appreciate that the utility model, the following examples are hereby given, and cooperates
Detailed description are as follows for attached drawing:
Please refer to FIG. 1 to FIG. 3, a kind of anti-impact ecotype groynes, including building dam body and abutment on bed course 5, in institute
The surface side that meets water for stating dam body and the abutment is fixed with anti-impact steel plate 6, on the dam body be equipped with it is multiple be located at design water level with
Under hole 4.Above-mentioned anti-impact steel plate 6 can reduce water flow directly washing away to dam body, safeguard dam stabilization.The shape in hole 4
At the metastable space of fluidised form, suitable habitat can be provided for fish and benthon.
In the present embodiment, in order to guarantee anti-impact effect, recommend the top mark height of the anti-impact steel plate 6 be higher than regulated water stage,
Lower than dam crest, the bottom of the anti-impact steel plate 6 is located at soil body certain depth.In order to save construction investment, building stones dosage is reduced,
The dam body is to be filled with stone made of 1 yard of lattice guest gabion is built in the lattice guest gabion, maintain by self gravity
The stability of dam structure, stress unit of the lattice guest gabion as total main body bind connection between lattice guest's gabion,
To ensure the globality of structure.Dam body uses gabion laid dry structure, and the mud between stone gap is conducive to plant growth.Lattice guest's stone
Cage 1 is to be woven using with improved corrosion, high intensity, the malleable mild steel wire of tool using machinery, has netting knot
Structure.In the present embodiment, interval, the migration channel as fish are equipped between the dam body and riverbank.Above-mentioned interval pushes away
Recommending width is 3~10m.The bed course 5 is made of the natural material making with water penetration, can be groynes structure
Installation provides smooth convenient execution conditions, while material is more environmentally-friendly, hydrophilic, has good ecological.For construction party
Just, abutment arc slope surface made of being filled as riprap.Alloy steel cage is covered in dam crest and abutment surface
The lower part of gauze pad 3, the alloy steel cage gauze pad 3 is quarry bed, and top is ecological pad, and the ecological pad is spread by ecology bag
At, soil and vegetable seeds rich in organic matter are provided in the ecology bag.The aperture of alloy steel cage gauze pad 3 cannot surpass
The partial size of jackstone block stone is crossed, alloy steel cage gauze pad 3 can protect abutment from current scour, while can provide for plant
Adhere to space, builds good habitat, while enhancing groynes stability, improve the ecological of groynes.In order to improve environmental protection
Property, the ecology bag is made of being woven as natural plant material.
It when construction, successively carries out from bottom to top: being laid with bed course 5, code builds lattice guest gabion 1, pell mell construction abutment, is laid with alloy-steel wire
Then cage gauze pad 3 installs fixed anti-impact steel plate 6.When code builds lattice guest's gabion 1, takes below design water level and alternately take in length and breadth
It connects, forms hole 4, be that there are inhabit habitat for the aquatiles such as fish.
Although being described above in conjunction with preferred embodiment of the attached drawing to the utility model, the utility model is not
