Description
Technical field
It the utility model is related to water conservancy marine traffic engineering technical field, more particularly to a kind of hydraulic reclamation area gabion discharge opening.
Background technology
With the continuous development of urbanization, the attraction of urban agglomerations population is original stronger, and urban population is more and more, right
In the supersaturation of the density of population on some coastal cities, existing land area, there is an urgent need to increase land area to expire
Sufficient city self-growth and the inhabitation work requirements of increasingly increased population.Many coastal cities use the side of reclamation by pumping filling
Method, to increase the land area in city, first, available by the silt displacement in Coastal beach lake, by pumping, as filler,
Play the effect of dredging environmental protection；Second, reclamation by pumping filling express delivery is fast, technical maturity, cost is relatively low.
Hydraulic reclamation refers to that the applied science technology that soil is transported to land or underwater point bar is filled, narrow sense will be dredged
On then refer to one kind that water front fill burrock, platform etc. by the soil in rivers,lakes and seas, is dug out and be sent to by dredger
Construction method.For Dredger Filling Engineering, hydraulic reclamation number of dropouts is always to perplex the key factor of such engineering cost and profit, for
The Dredged marerial in land on hydraulic reclamation is excavated, it is ensured that it is effectively precipitated and be not lost in, and is the ring of key one of cost control, and discharge opening is set
The success or failure of meter are the key point of hydraulic reclamation number of dropouts control again, and it largely determines the profit and loss situation of Dredger Filling Engineering.Meanwhile
After agitation hydraulic reclamation disembarkation, Yu Shui can be discharged into external environment condition after need to carrying out certain precipitation process for river course or ocean dredging thing,
Effectively control number of dropouts, i.e., the concentration of water more than hydraulic reclamation is effectively controlled, reduce destruction of the Dredger Filling Engineering to marine environment.
A kind of hydraulic reclamation area charge for remittance mouth is buried tube type discharge opening, for buried tube type discharge opening, although it has construction letter
Singly, the advantages of cost is low, but have the following disadvantages：1st, bad adaptability, it is impossible to manual control water level；2nd, easily to discharge opening week skirt
Low bank between fields causes to wash away, and encloses low bank between fields and easily caves in；3rd, barged-in fill number of dropouts is more serious, and it is larger to enter extra large concentration of wastewater, and environment is impacted；
4th, regular maintenance amount is big.
The discharge of existing conventional hydraulic reclamation area tail water but be present, as discharge opening overflow elevation is uncontrollable, be permitted
Multiple-project tail water directly covers cofferdam and is discharged into off-lying sea；For discharge opening without filter effect, the hydraulic reclamation mud mobility after preliminary sedimentation is high, holds
Off-lying sea is easily discharged into by the gap outflow of discharge opening, the hidden danger of pollution is brought to ocean and periphery water system.It is conventional in addition to sluice
Mouth structure stability and bad hydraulic permeability, for the uneven depression of beach landform without self adjustment capability, it is hidden to there is larger safety
Suffer from.
The content of the invention
The purpose of this utility model is to provide a kind of hydraulic reclamation area gabion discharge opening, enable water in hydraulic reclamation area silt and
When discharge, while play filtering tail water in fine grained effect.
To achieve the above object, the utility model uses following technical scheme：A kind of hydraulic reclamation area gabion discharge opening, including let out
Mouth of a river pedestal and gabion.The discharge opening pedestal combination cofferdam is arranged on discharge opening position, and the gabion is in the discharge opening base
Seat stacked on top is into gabion wall.Gabion wall side both sides are connected with cofferdam respectively, described solid block of stone of gabion.The gabion
Loaded filter is set in the middle part of wall on water (flow) direction is blocked, and the gabion wall top portion sets overfall.
Further, the gabion by step slope and is staggeredly stacked into gabion wall above the discharge opening pedestal.
Further, the gabion is to be formed by galvanized steel wire netting colligation and the cuboid of top open-ended.The gabion
Length be 0.8~1.2m, width is 0.8~1.2m, is highly 0.4~0.6m, and mesh size is 10cm × 12cm.Described piece
A diameter of 15cm ~ 20cm of stone.
Further, river bottom protection sand pocket is equipped with above described discharge opening pedestal, one layer is laid above the river bottom protection sand pocket
Non-woven geotextile, the gabion are staggeredly stacked into gabion wall above the non-woven geotextile.
Wherein, described loaded filter folds parcel rubble by non-woven geotextile and formed, and thickness is 0.4 ~ 0.6m.
Further, described discharge opening pedestal is provided with water inlet side into water slope, water inlet slope top
One layer of non-woven geotextile is laid, bank protection sand pocket is laid above the non-woven geotextile.The discharge opening pedestal is in delivery port side
Provided with water outlet slope, bank protection sand pocket is laid on the water outlet slope.
Wherein, described water inlet ramp slope is 1:1.5, the gradient on described water outlet slope is 1:6.The bank protection sand pocket
Height be 0.2 ~ 0.3m.
Further, sand pocket is filled in the junction of the gabion wall side both sides and cofferdam.
The utility model has the advantages that：
（1）, the utility model discharge opening use gabion based on component, both can neatly adjust hydraulic reclamation area tail water
Overflow high level and overflow width, the Stability Analysis of Structures of discharge opening, good water permeability can be ensured again.When hydraulic reclamation water is smaller, due to
The high permeability of gabion, tail water can be directed through gabion discharge.When hydraulic reclamation water is larger, overfall can be flexibly controlled again
Width, tail water is set to discharge in time.
（2）, in the middle part of gabion set geotextiles to wrap up rubble loaded filter, can be with while can making discharge opening continuous draining
The fine particle in tail water is filtered, puts to tail water the pollution to environment.Other gabion itself has excellent structural stability can,
Good water permeability, flexible structure.There is self very strong adjustment capability for uneven depression, more conventional stoplog culverts and water gates discharge opening has
Obvious advantage, avoid the risk that discharge opening collapses.
（3）, gabion by step slope and be staggeredly stacked into gabion wall, tail water that can be larger to flow velocity carries out energy dissipating.
