Abstract
The concave herbaceous field structure of sponge the idea of the city, including both sides are green with planting, concave herbaceous field and overfall, and concave herbaceous field is green relative to both sides to plant recessed depth h, and gradient width when concave herbaceous field is recessed is b, makes h：b≤1:3, concave herbaceous field is followed successively by rammed earth layer, small crushed stone layer, geotechnological layer of cloth, plantation layer and aquitard from down to up, fixed range sets overfall between concave herbaceous field, connection overflow well below overfall, overflow well is set with overfall junction cuts dirty net, some water-permeable pipes are connected on overflow well, the bottom of overflow well is connected with big metalling back cover thick 300mm, the bottom of overflow well and the rainwater connecting tube of city planting ductwork.The utility model combination sponge city retaining theory, effectively alleviate urban waterlogging, cut down urban runoff pollutional load and saved water resource simultaneously, concave herbaceous field design improves rainwater-collecting ability, rainfall runoff substantially reduces the pollution of early-stage rainwater after soil and sand stone layer filtering.
Description
Technical field
The utility model is related to Rainwater Resources and utilized and municipal drainage technical field, more particularly to one kind combines sponge
The concave herbaceous field structure of the idea of the city.
Background technology
In recent years, with the quickening of Urbanization in China, the continuous expansion of city size, a large amount of culture cities
Hardened ground increase, the increase of the underlying surface Permeable stratum area of hardened ground causes rainwater to add through flowing coefficient increase, conflux networks
It hurry up, so that the general stream of street flood and groundwater storage are reduced when causing urban storm weather, thereby produce serious municipal water
Soil is lost in and problem of drainning off floodwaters.For runoff pollution is serious, amount of salt in groundwater is higher, facility bottom percolation identity distance from it is seasonal most
Phreatic high or lithosphere are less than 1m and are less than 3m region apart from building foundation level distance, should take necessary antiseepage
Measure, prevents the generation of secondary disaster.
The content of the invention
The utility model is to solve the above problems, there is provided a kind of concave herbaceous field structure of combination sponge the idea of the city.
Technical solution adopted in the utility model：
The concave herbaceous field structure of sponge the idea of the city, including both sides are green with planting, concave herbaceous field and overfall, up concave type
Greenery patches is green relative to both sides to plant recessed depth h, and h is 100~200mm, and gradient width when concave herbaceous field is recessed is b, is made
h：b≤1:3, concave herbaceous field is followed successively by rammed earth layer, small crushed stone layer, geotechnological layer of cloth, plantation layer and aquitard from down to up,
Fixed range sets connection overflow well below overfall, overfall between concave herbaceous field, and overflow well is set with overfall junction
Cut and some water-permeable pipes are connected on dirty net, overflow well, the bottom of overflow well is with big metalling back cover thick 300mm, the bottom of overflow well
The rainwater connecting tube connection of portion and city planting ductwork.
Described plantation layer soil thickness is not less than 250mm, is mixed by sand, compost and loamy soil, and infiltration coefficient >=1 ×
10-5m/s。
Described overfall elevation of top is higher than 50~100mm of concave herbaceous field.
Described small crushed stone thickness degree is not less than 200mm.
Safeguard structure is set around described overfall.
The beneficial effects of the utility model：The utility model combination sponge city retaining theory, effectively alleviates in city
Flood, cuts down urban runoff pollutional load and has saved water resource simultaneously, concave herbaceous field design improves rainwater-collecting ability, rainwater
Runoff substantially reduces the pollution of early-stage rainwater after soil and sand stone layer filtering.

Fig. 1 is longitudinal profile schematic diagram of the present utility model.
Wherein：1- aquitards；2- kinds plant layer；3- geotechnique's layer of cloths；4- small crushed stones layer；5- rammed earths layer；6- rainwater is connected
Pipe；7- overflow wells；The big metallings of 8-；9- water-permeable pipes；10- safeguard structures；11- cuts dirty net；12- overfalls.
Embodiment
The concave herbaceous field structure of sponge the idea of the city, including both sides are green with planting, and concave herbaceous field and overfall 12 are recessed
Formula greenery patches is green relative to both sides to plant recessed depth h, and h is 100~200mm, and gradient width when concave herbaceous field is recessed is b,
Make h：b≤1:3, concave herbaceous field is followed successively by rammed earth layer 5, small crushed stone layer 4, geotechnological layer of cloth 3, plantation layer 2 and from down to up
Fixed range sets overfall 12 between aquitard 1, concave herbaceous field, and the lower section of overfall 12 connects overflow well 7, and overflow well 7 is with overflowing
The junction of head piece 12, which sets to cut, connects some water-permeable pipes 9 on dirty net 11, overflow well 7, the bottom of overflow well 7 is with the big of 300mm thickness
The back cover of metalling 8, the bottom of overflow well 7 and the rainwater connecting tube 6 of city planting ductwork are connected.
Described plantation 2 soil thickness of layer are not preferably less than 250mm, are mixed by sand, compost and loamy soil, and infiltration coefficient >=
1×10-5m/s。
The described elevation of top of overfall 12 is higher than 50~100mm of concave herbaceous field, and surrounding sets safeguard structure 10.
Described small crushed stone 4 thickness of layer are not less than 200mm.
The concave herbaceous field ground of design is less than surrounding ground or road, and concave herbaceous field implants preferably combine local landscape
Drought-enduring, the waterlogging kind of selection, and provided with overfall 12, it is ensured that the overflow discharge of runoff during heavy rain, oozes when under concave herbaceous field
When scarce capacity can not effectively exclude the rainwater of delay, the water-permeable pipe 9 added plays good drainage effect, effectively solves to drain off floodwaters
Problem.
One embodiment of the present utility model is described in detail above, but the content is only of the present utility model
Preferred embodiment, it is impossible to be considered as being used to limit practical range of the present utility model.It is all to be made according to present utility model application scope
Equivalent change with improve etc., all should still belong within patent covering scope of the present utility model.
