Description
Technical field
The utility model belongs to Hydraulic and Hydro-Power Engineering field, relates in particular to a kind of ecological earth and rockfill dam.
Background technology
Hydropower Project is made up of the building such as barrage, spillway, water conservancy diversion and flood discharging tunnel, generating diversion tunnel, factory building.Its
In barrage it is mostly important, current guard dam has earth and rockfill dam, concrete dam, earth and rockfill dam, concrete core-wall dam etc..Or
Barrage can be all typically built between river course and arable land, prevents the water in river course from flowing into arable land, or river course rises and rushes in village.
Current barrage has rock-fill dams, concrete dam, earth and rockfill dam, concrete core-wall dam etc..Current earth and rockfill dam is typically employed in
On small river course.This earth and rockfill dam, concrete core-wall after a period of time can crack, barrier performance is poor, once and river course
Rise, its fluid erosion prevention performance is low, it is easy to rushed across.In addition, these current earth and rockfill dams, when stormy waves is larger, water wave is easily covered very much
Earth and rockfill dam, wind wave prevention ability.
The content of the invention
The purpose of this utility model is to overcome a kind of above-mentioned not enough barrier performance of offer and the strong ecology of protecting against shock performance
Earth and rockfill dam.
Mesh of the present utility model is achieved through the following technical solutions：
A kind of ecological earth and rockfill dam, including the native rock layers dam body being arranged on above-ground route and riverbed line, in native rock layers dam body
Outside is provided with rock revetment, is provided with the varying level position of rock revetment upstream face side and chooses stream bank, choose stream bank with
The fill stratum of suitable planting plants is provided between rock revetment, the diverse location in native rock layers dam body back side side is provided with
It is adapted to the fill stratum of planting plants, the centre of native rock layers dam body is provided with the ground below concrete core-wall, concrete core-wall
Concrete core-wall base is embedded with line, concrete core-wall is arranged on concrete core-wall base, in concrete core-wall base
Two-row curtain grout ing layer is just being provided below, the concrete core-wall is up-narrow and down-wide trapezoidal, and concrete core-wall includes coagulation
Soil layer and the reinforcement steel plate being embedded in concrete layer are constituted, and the two ends of every block of steel plate set crimping, and two ends crimping side respectively
To on the contrary, reinforcement steel plate and concrete layer are complex as a whole composition concrete core-wall.
Steel reinforcement cage is provided with above-mentioned ecological earth and rockfill dam, the concrete layer.
Above-mentioned ecological earth and rockfill dam, the reinforcement steel plate is penetrated into concrete core-wall base.
Using above-mentioned technical proposal, the utility model has the advantage that：Due to being provided with one of coagulation in the middle of native rock layers
Native core-wall, concrete core-wall includes concrete layer and is embedded the reinforcement steel plate in concrete within doors, and in the concrete core wall base
Two-row curtain grout ing layer is provided below in seat, the utility model is not only strengthened barrier performance, but also dam body greatly improved
Bulk strength, improve the anti-erosion property of dam body.It is possible that the raising antiseep in soft rock body can also be adapted to simultaneously
Property.In addition, when when blowing, water wave is overflow on rock revetment, choosing stream bank can play a part of stopping and eliminating water wave.Banket
Layer can play effect of ecological, environmental protective again with planting plants while attractive in appearance.
Brief description of the drawings
