Description
Technical field
The utility model is related to bank of river construction field, the bank of river structure of more particularly to a kind of flood control.
Background technology
Sponge city, is new generation of city storm water man- agement concept, refers to that city is adapting to environmental change and reply rainwater band
The aspects such as the natural calamity come have good " elasticity ", also referred to as " water elasticity city ".
The water suction when Constructing ideas in " sponge city " emphasize rainfall, retaining, infiltration, water purification, it is necessary to when the water that will store " release
Put " and be used.Currently known bank of river is generally stone masonry embankment, armored concrete embankment etc., by concrete, slurry
Stone-laying forms soil-baffling structure will be kept apart after river course and dike, with ensureing riverbank security stabilization, room for promotion utilization rate, but levee body
Lower water and river poor connectivity, backfill material and use cohesive soil, poor permeability more in addition after barricade, levee body lacks Regulation capacity, difficult
Built with regulating and storing naturally with meeting modern city, the requirement in " sponge-type " city of naturally osmotic and self-purification function, and
Directly near water, the decline of Regulation capacity easily causes river flood rises suddenly and sharply and breaks bank of river, forms city flood.
Utility model content
The purpose of this utility model is to provide a kind of bank of river structure of flood control, with river course Regulation capacity is improved, drops
The advantage that low flood occurs.
Above-mentioned technical purpose of the present utility model technical scheme is that：
A kind of bank of river structure of flood control, including embankment and concrete dykes and dams, the embankment include successively from top to bottom
Embankment road surface, metalling, coarse sands layer and natural soils layer, the closed conduit connected with coarse sands layer is provided with the natural soils layer,
It is connected with reverse osmosis passage between the closed conduit and bottom of river channel, connection metalling is provided with the concrete dykes and dams and river course is let out
Big vast passage.
Using said structure, when water level rises to flood stage in river course, that is, when exceeding flood discharge passage, current in river course
Can be flowed into metalling by flood discharge passage, due to there are many holes in metalling, while space is accommodated, water can pass through
Hole penetrates into coarse sands layer, and the hole in coarse sands layer diminishes, and can reduce lower infiltration rate degree, reaches the effect of buffering so that in metalling
Substantial amounts of water is saved, slows down water level rise；And the water in metalling after being buffered by coarse sands layer can be penetrated into slowly slightly
Layer of sand, the water for reaching coarse sands layer bottom enters closed conduit, is saved in closed conduit, to reach the effect of dual flood discharge, works as river water level
During less than flood stage, during water in closed conduit can send back to river course by reverse osmosis passage.
More preferably：The embankment road surface is provided with vegetation side slope away from the side in river course, and the vegetation side slope includes
Cultivated plant soil horizon above coarse sands layer.
Using said structure, plant can be planted at vegetation side slope, meanwhile, plant soil horizon by ploughing in rainy day rainwater
After can penetrate into coarse sands layer, and feed the water into closed conduit, finally send into river course, play a part of water delivery.Located at coarse sands layer top
Plant the moisture in soil horizon to supply plant strain growth for keeping ploughing.
More preferably：The vegetation side slope is provided with creepage concrete road surface away from the side in river course, and the infiltration is mixed
Solidifying soil surface is located at metalling top.
Using said structure, in rainy day rainwater can penetrate into metalling, then coarse sands layer is penetrated into, and in coarse sands layer, had
Effect reduces the problem of surface gathered water；Wherein, because metalling side is to plough to plant soil horizon, coarse sands layer during lower section can extend rain
Savings time of the water in metalling and coarse sands layer so that after the rain in the metalling and coarse sands layer below creepage concrete road surface
Water can also play moisten plough plant soil horizon effect.
More preferably：It is provided between coarse sands layer and natural soils layer below the creepage concrete road surface
Waterproof geotechnique's layer of cloth.
Using said structure, creepage concrete road surface is blocked and penetrates into the water on ground penetrating into the soil below coarse sands layer,
The effect for keeping resistance of soil is played first, secondly water can be made to import closed conduit in being stored in coarse sands layer.
More preferably：The thickness of the metalling and coarse sands layer from creepage concrete road surface to embankment road surface is passed successively
Increase, and coarse sands layer bottom below the vegetation side slope is inclined to set.
Because the fractured-rock layer thickness below road need not be too thick, and the metalling below embankment road surface needs to play retaining
The effect of flood discharge, so thickness requirement is larger, therefore uses said structure, reduces cost input, while in can improving coarse sands layer
Water imports the speed of closed conduit.
More preferably：The flood discharge passage is set diagonally downward in river course towards metalling.
Using said structure, being obliquely installed can increase the speed that water is entered into metalling by hydraulic pressure, and raising is let out
The speed of flood.
More preferably：The upper and lower two side of the closed conduit is poured using creepage concrete, and is also set up in lower wall
There are unidirectional osmosis geotextiles, arranged on left and right sides wall is poured using water-proof concrete and formed.
Using said structure, in realizing that coarse sands layer water returns to river course into closed conduit and closed conduit reclaimed water.
More preferably：The lower wall bottom of the closed conduit is provided with the rubble passage connected with river course.
Using said structure, the speed that closed conduit reclaimed water returns to river course can be slowed down using rubble passage, it is ensured that flood discharge speed
Much larger than back-flow velocity.
In sum, the utility model has the advantages that：With metalling, coarse sands layer and the road retaining of closed conduit three
Set, reservoir storage is big；Simultaneously closed conduit reclaimed water is reduced using the control to seepage velocity to be back in river course to have guaranteed
To the effect of useful storage, excellent flood discharge effect is reached with this.
