Embodiment 1: a kind of artificial lawn water-storing device for sponge city, including turf 1, the bottom of the turf 1
For pedaline base fabric 2, it is clathrum 4 in the lower section of pedaline base fabric 2, several mesh 5 is distributed on clathrum 4；Described
The lower section of clathrum 4 is to be laid with smooth pebble layer 6, and the lower section of pebble layer 6 is to be laid with smooth metalling 7, metalling 7
Lower section be sand stone layer 8, the lower section of sand stone layer 8 is the water purification layer 10 with several water seepage holes, water purification layer 10 and sand stone layer 8 it
Between be equipped with permeable geotextile layer 9, the water purification layer 10 is the channel design that brick mix structure is built, the top of water purification layer 10
It is provided with several water seepage holes, the lower section of water purification layer 10 is the drainage blanket 11 that the channel that brick mix structure is built is constituted, wherein in water purification
The lower layer upper surface of layer 10 and drainage blanket 11 is equipped with anti-seepage geomembrane 13.It is arranged between the pedaline base fabric 2 and clathrum 4
There is PE turf fibre plate 3.The clathrum 4 is laid with using Ceramic water-permeable brick.The drainage blanket 11 is protruded by aqueduct 12
Into pedaline base fabric 2.The distribution density of the aqueduct 12 is 5/square meter, using double-wall corrugated pipe.The turf 1 uses
Water resistant plant.The ratio between height between the water purification layer 10 and drainage blanket 11 is H1:H2=1:1.5.Between the aqueduct 12
Distance A is not less than 30cm.
As shown in Figure 1, the artificial lawn water-storing device for sponge city described herein, the skill mainly solved
Art problem is the infiltration and filtering how realized to natural precipitation, and how to realize and relieve in the biggish situation of natural precipitation
Urban waterlogging.
In order to realize the infiltration and filtering to natural precipitation, the turf 1 that water-fast plant forms is used in this application,
The planting density of turf 1 should be controlled in 25 ~ 30 plants/square meter, and preferably selected and carried out consolidating for turf 1 on pedaline base fabric 2
Fixed and constraint, the destruction of turf 1 caused by avoiding rainwater excessive.Pedaline base fabric 2 uses three-decker, respectively PP cloth, nothing
Woven fabric, grid cloth three-decker are combined.Wherein the PP cloth is that terylene material weaves, with elasticity is good, is not afraid of
The features such as extruding, quick-drying, easy cleaning, non-woven fabrics have it is moisture-proof, ventilative, flexible, quality is light, it is not combustion-supporting, be easy decomposition, nontoxic nothing
It is irritation, also recyclable；Grid cloth then has high intensity, anti-tortuous, waterproof heat resistant, good permeability, and coating bonds jail etc.
Advantage.The pedaline base fabric 2 that above-mentioned three-decker is compounded to form can guarantee enough service life in use, in turn
Guarantee the integrality of turf 1.
It is latticed plate body structure for the PE turf fibre plate 3 being laid with below pedaline base fabric 2, turf can be used as
1 support substrate, in latticed structure filled with compacting factor be 0.95 plain soil layer, thus be better achieved support with
Precipitation water body is sunk down into clathrum 4.After the PE turf fibre plate 3 and clathrum 4 of filling soil layer of being always or usually as specified contact, also need to adopt
Use permeable geotextiles as the isolation of soil layer.Clathrum 4 is the plate body structure for being layed in 6 top of pebble layer, is distributed with thereon
Several mesh 5 passed through for water body.By PE turf fibre plate 3 and the dual baffle of clathrum 4, turf 1 can be effectively reduced
In the particles such as the soil that is scattered enter or blocking mesh 5.
The pebble layer 6 uses the substantially uniform cobblestone composition or close with cobblestone of size in this application
Material constitute.Its role is to can effectively improve the supporting role of turf 1, avoid by the supporting role of cobblestone 6
Matrix caused by precipitation is excessive or fluid is excessive collapses.And the gap between pebble layer 6 should control and occupy
The average grain diameter of the 25 ~ 35% of its volume, the cobblestone used in pebble layer 6 should be in 20 ~ 50mm.
In the metalling 7 that the lower section of pebble layer 6 is compared with small particle.The effect of metalling 7 be to the water body of infiltration into
Row secondary filter.Its metalling 7 use partial size should be the 30 ~ 40% of the used partial size of pebble layer 6, i.e., 6 ~ 20mm it
Between, gravel particle there are void space occupation rate should control the 30 ~ 35% of its unit volume.
Be generally more short grained sand stone layer 8 in the lower section of metalling 7, sand stone layer 8 be used for the water body of natural precipitation into
The further filtering of row.Further filtered water body enters in the water purification layer 10 of lower section.Water purification layer described herein
10 be the channel passed through for water body built using brick mix structure, the channel can in urban pipe network recirculated water pipe network or
Secondary pipe network carries out connection.It should be noted that due to using the 8 smaller filter layer of this particle of sand stone layer, so needing
Permeable geotextile layer 9 is equipped between the water seepage hole above water purification layer 10 and sand stone layer 8.Permeable geotextile layer 9 can have
Effect prevents the sandstone of sand stone layer 8 to be lost, and can guarantee to permeate the unobstructed discharge of water, and can effectively ensure that not by sand stone layer
8 fine earth particle silting.
When precipitation is smaller, rainwater a part of can be absorbed by turf 1, and rest part penetrates into water purification layer 10.
And when precipitation is larger, rainwater need other device carry out absorb rainwater can be prevented to be flowed into hardening road surface make
At runoff.
The lower section of the water purification layer 10 is additionally provided with the identical drainage blanket 11 of structure therewith in this application.Drainage blanket 11
Inside it is provided through above structure, including water purification layer 10, permeable God in charge of the Earth's layer of cloth 9, sand stone layer 8, metalling 7, pebble layer 6, net
Compartment 4, PE turf fibre plate 3, pedaline base fabric 2, aqueduct 12.Aqueduct 12 uses double-wall corrugated pipe to make to better ensure that
Use performance.In this application, the aqueduct 12 is hollow tube, and the end face on top extend into the upper surface of turf 1 simultaneously
It is concordant therewith.The structure being arranged in this way can be relieved effectively under the biggish weather condition of the precipitation such as heavy rain, 1 surface water flow of turf
Inflow to bottom discharge layer 11.And when 1 surface of turf does not become biggish runoff, the water body on turf 1 is will not
Into aqueduct 12, flowing or lesser runoff are flowed into aqueduct 12, do not interfere with normal water body infiltration.
And the water body entered in water purification layer 10 and drainage blanket 11 in order to prevent is interpenetrated by brick mix structure, net
The lower surface of water layer 10 and the lower surface of drainage blanket 11 are covered with anti-seepage geomembrane 13.Anti-seepage geomembrane 13 has erosion resisting,
It has good effect in acid, the erosion of alkali, salt, and its tensile strength is high, low elongation, vertically and horizontally uniformly, tearing toughness is high, resistance to for deformation
The features such as mill function admirable, water-resisting property is strong, the discharge of water body can be effectively facilitated, reinforce the isolation to water body.In this application,
In view of the difference using operating condition, the specification for needing to use needs the anti-seepage geomembrane in 300g/ square meter or so.
