The content of the invention
Present invention aim to address problems of the prior art, there is provided a kind of utilization that can effectively improve water resource
Rate and a kind of urban road both sides sunk type Greenland Irrigation system for saving the maintenance costs in greenery patches.
To achieve the above object, the present invention adopts the following technical scheme that：A kind of urban road both sides sunk type Greenland Irrigation
System, the sunk type greenery patches are arranged between road and pavement, and the row concordant with road surface is provided with road edge
Water window, the draining window connection road and sunk type greenery patches；The sunk type greenery patches close to the edge on pavement be provided with
The draining window of greenery patches flush, the draining window connection sunk type greenery patches and water storage canal；Filling is installed on sunk type greenery patches
Device is irrigate, the irrigation rig connects with water storage canal.
Preferably, the sunk type greenery patches is higher than close to the one end on pavement close to one end of road.
Preferably, some gutters are provided with the sunk type greenery patches, the both ends in the gutter pass through row respectively
Water window connects with road and water storage canal.
Further, draining window is provided with the two side in the gutter.
Further, the surface in the gutter is provided with cover plate.
Preferably, the water storage canal is concrete structure, and it is internally provided with some control sluice, the control sluice and water storage
The bottom and both sides of canal are fixed, and control the top of sluice with being provided with spilling water duct at the top of water storage canal.
Water on road edge setting draining window, road can be automatically flowed into greenery patches；When moisture mistake in soil of greenbelt
It when more, can penetrate into gutter, be flowed into by gutter in water storage canal, it is unnecessary when water storage channel water amount reaches control line
Water river, river, lake nearby can be flowed into by water channel；When road forms the gradient, the subsection setup control sluice in water storage canal can
Effectively control water one-level one-level flows to low area.
Assuming that each sprinkling truck loads 15 tons of water, the watering time is 1.5 hours, and speed is 15,000 ms/h, can be counted
The about sprayable km of greenery patches 22.5 in each sprinkling truck is calculated, i other words each sprinkling truck can complete pouring for 11.25 km roads
Fill work.If greenery patches is designed with the present invention, the abundant area of rainfall can not almost set out sprinkling truck, arid area
Sprinkler can be reduced, saves great lot of water resources.
By taking five million cities as an example：City major trunk roads afforest about 300 kilometers, and expressway greening about 197 is public
In, state's provincial highway afforests about 452 kilometers, and village of counties and townships road afforests about 1700 kilometers, and traffic route greening amounts to about 2649 kilometers, such as
Fruit is all poured once, will be about setting out the train number of sprinkling truck 235 of 15 tons of carrying capacity.Rough calculation, greenery patches is all poured once,
Including labour cost, oil consumption expense, water rate and vehicle wear and tear expenses etc., the funds used are more than 100,000 yuan.If greenery patches is according to this hair
It is bright to be designed, substantial amounts of financial charges will be saved every year.
In addition, sprinkling truck when being worked on road, because speed is slower, has a certain impact to traffic, and the water sprayed
Often it is splashed to the vehicle passed by and pedestrian.With the present invention, it is possible to reduce number is set out on sprinkling truck, reduces sprinkling truck pair
The influence of traffic, reduce exhaust emissions.
The present invention compared with prior art, has the following advantages that：
1st, the utilization rate of water resource is improved.
2nd, reduce sprinkling truck sets out number, reduces the influence to traffic, reduces exhaust emissions.
3rd, the maintenance costs in greenery patches is saved.
1-7 is described in further detail to the present invention below in conjunction with the accompanying drawings:
As Figure 1-3, urban road 1 is central raised, slightly above two edges, and its both sides is sunk type greenery patches 2, people successively
Trade 3, separated between road, sunk type greenery patches and pavement with curb 6, the surface in sunk type greenery patches 2 is less than road 1 and people
Trade 3, and be higher than close to one end of road close to the one end on pavement, it is provided with the curb 6 of road edge and road
The draining window 7 of flush, the draining window 7 connect road 1 and sunk type greenery patches 2；In sunk type greenery patches close to pavement
The draining window 7 with greenery patches flush is provided with curb 6, the draining window 7 connects sunk type greenery patches and water storage canal 8；
Shower tap 4 is poured in installation on sunk type greenery patches 2, and the pouring Shower tap 4 connects with water storage canal 8；Water storage canal is concrete
80 structures, it is arranged at below the earth's surface of pavement 3.
As shown in Fig. 1,4,5, some gutters 5 are provided with sunk type greenery patches, the bottom and two sides in gutter are
The structure of concrete 51, the both ends in the gutter are connected by draining window 7 with road 1 and water storage canal 8 respectively, the gutter
Draining window 7 is provided with two side, the surface in the gutter is provided with cover plate 50, when excess moisture in soil of greenbelt
When, it can be penetrated into gutter 5, be flowed into by gutter in water storage canal 8, when water storage channel water by the draining window 7 in side wall
When amount reaches control line, unnecessary water can flow into river, river, lake nearby by water channel.
As shown in Figure 6,7, when road 1 forms the gradient, the subsection setup control sluice 81 in water storage canal 8, control sluice is with storing
The bottom and both sides of water channel are fixed, and are controlled the top of sluice and are set spilling water duct 82 with the top of water storage canal, can effectively control water
One-level one-level flows to low area.
Above-described embodiment is only the further explanation to the present invention, is not construed as limiting the invention.Between water storage canal
Away from and amount of capacity can be designed according to local rainfall, enrich region for rainwater, the horizontal row of adding on greenery patches
Ditch, lawn watering speed can be accelerated, avoid that greenery patches is flooded and rainwater is diffused on road, gutter size drops according to locality
Rainfall is designed, and during dry season, opens pumping equipment, is extracted the water in water storage canal out automatic spraying to greenery patches, is poured water spray
The quantity of tap is poured scope according to greenery area size and tap and installed；, can be in when road center is provided with greenery patches
Centre greenery patches periphery sets water storage canal.
