Abstract
The invention provides a rainwater collecting and storing system of a sidewalk and greenbelts on the two sides. The system is composed of the sidewalk, a water permeable pipe and the greenbelts. The sidewalk is a road formed by laying water permeable bricks. The water permeable pipe is embedded in a road under layer, and a base layer, a leveling layer and a brick layer are arranged on the road under layer. The greenbelts are composed of planting base layers, coarse sand filter layers and crushed pebble layers. The planting base layers adopt artificial soil. Nonwoven geofabrics are arranged between the crushed pebble layers and the coarse sand filter layers. Garden bounding walls are built in the positions, from the upper edge of the road under layer to the position higher than the surfaces layers of the greenbelts, of the joints of the greenbelts and the road. The system is suitable for the ground or underground spatial top plates, and water can be filtered, stored and collected while the greenbelt area is increased. Greenbelt planting matrixes are low in weight and capable of holding water and effectively filtering harmful substances in rainwater, plants are not lack of water in the dry season with little rain, the rainwater can be filtered through the layers and is gathered at the water permeable pipe along with the gradient and collected to municipal water collecting pipelines in the heavy rainy season, and thus recycling of the water is promoted.
Description
Technical field
The invention belongs to urban construction design field, specifically provides a kind of footpath, greenery patches and harvests water system.
Background technology
China is the country of a drought and water shortage, but and is the most country of water consumption in the world.In recent years, municipal water
The tensity increasingly significant of resource, but the city that much rainfall is plentiful can not drainage waterlogging prevention in time.Summer in 2015, Hubei,
The ground such as Jiangsu, Anhui, Jiangxi, Zhejiang, Guizhou, Guangxi " a drenching rain ", national 20 provinces（Area, city）Tens of millions of people is disaster-stricken, greatly
Amount crops suffer damage, and storm flood causes the economic loss of tens billion of units directly to us, build compeling for sponge city
Cutting property becomes urgently to treat.Sponge city, is new generation of city storm water man- agement concept, refers to that city is adapting to environmental change and answering
The aspects such as the natural disaster brought to rainwater have good " elasticity ", water suction, water-retention, infiltration, water purification when raining, will when needing
The water " release " that stores simultaneously is used, and the lance of China's short water supply and rainy season flood is effectively alleviated in effective protection ecological environment
Shield.Making " sponge city " answers treatment in accordance with local conditions to be resorted to the measure of own characteristic.City increases Green Space Construction, strengthens greenery patches and stores
Water water-collecting capacity and draining in time, are a kind of thinkings for building sponge city.In addition to greening is increased in ground earth's surface, can also be to city
City's shallow underground engineering such as business, top board of entertainment type suitably carries out Greening Design.
The content of the invention
For the problem that prior art is present, the present invention is intended to provide a kind of footpath is permeable road, Green Space Design is
Water-retention water conservation, can effectively alleviate the product flood of heavy rain, torrential rain, make full use of greenery patches and Route for pedestrians to collect the water-retention for discharging rainwater
System.The present invention is applied to ground or underground space top board, while increasing greenery area, can drainage water-retention catchment.
The technical solution used in the present invention is：A kind of footpath, greenery patches harvest water system, and its composition includes footpath, saturating
Water pipe, greenery patches and garden wall, arrange water-permeable pipe under the footpath, the distribution of green areas is in footpath both sides；
The footpath be water permeable sidewalk, footpath top layer be permeable brick layer, permeable brick layer bottom be followed successively by permeable screed-coat,
Permeable cement stabilized macadam base, granular cushion；The granular cushion is layed on top board or ground, and footpath
Skin surface is apart from top board or ground 500-600mm；
Its bottom of the greenery patches is layed on top board or ground for crushed gravel filtering layer, is equipped with coarse sand filter on crushed gravel filtering layer successively
Layer, plantation basic unit；The plantation substrate surface is higher than water-permeable brick layer surface, and the discrepancy in elevation is 300-600mm；In footpath and greenery patches
Intersection garden wall to the discrepancy in elevation be provided with from granular cushion be higher by 100mm, the edge in greenery patches from ground or
It is also equipped with garden wall on top board, the setting of garden wall enables to the water on top to dirty, it is to avoid water horizontal mobility.
The water-permeable pipe is plastic blind-ditch water-permeable pipe, and it is layed in granular cushion central authorities, graded broken stone along footpath
The high 200-300mm of bed course, permeable bore is 100-140mm, and water-permeable pipe has permeable tube socket.
The crushed gravel thickness of filter bed is 300-400mm, particle diameter 50mm ± 5mm；The coarse sand thickness of filter bed is 200-
300mm, particle diameter is 4mm ± 1mm.
Non-woven geotextile is provided between the crushed gravel filtering layer and coarse sand filtering layer.
The top board or ground are set to edges of regions to center certain slope, and center is relatively low, and edges of regions is higher, slope
Spend for 1%-3% such that it is able to ensure that water collects to center, and be collected by water-permeable pipe.
The greenery patches crushed gravel filtering layer is connected with granular cushion.
The garden wall upper surface is 100mm with the difference in height on greenery patches surface.
The plantation basic unit is a kind of artificial soil, and compounding mass ratio is red soil：Vermiculitum：Perlite：Peat=5：
1：1：3, planting matrix thickness should determine according to planted vegetation pattern.
Compared with prior art, the invention has the beneficial effects as follows：When the present invention is for earth's surface ground or underground space top board, can increase
Plus greenery area, while energy drainage water-retention is catchmented；The planting matrix light weight water conservation in greenery patches, can effectively filter nuisance in rainwater
Matter, in drought season, plant not hydropenia, in heavy showers season, rainwater can be pooled to permeable by filtering layer by layer along the gradient
At pipe, municipal collecting conduit is collected into, promotes the recycling of water.When the present invention is for ground, moreover it is possible to make rainwater penetrate into ground
Lower recharge groundwater, while also a part of water can be collected by water-permeable pipe, heavy rain, continuous rainy weather energy rapid infiltrated, draining,
Avoid surface gathered water.
The planting matrix layer in greenery patches is using water-retention and the preferable Vermiculitum of retentiveness, perlite and common red soil, fertile soil
Compounding, can effectively attract deposit filtration rainwater；The rainwater while water-storage-drainage layer of shallow-layer greenery patches bottom can effectively regulate and store；200mm thickness
The planting matrix water holding time is 4~5d, is 2 times of typical laterite earth.Greenery patches is entered to rain water pollutant COD, NH3-N, TN, TP
Row purification, clearance respectively 54.5%~60.3%, 46.3%~69.3%, 48.5%~61.0% and 46.3%~54.0% it
Between, purification is mainly reflected in planting matrix layer；System arid water conservation, middle light rain water-retention, heavy rain heavy rain integrate draining, and water-retention
With catchment while carry out or water-retention, seep water and catchment while carry out, rainwater under the system by oozing, stagnant storage, purification, reuse, most
Afterwards remainder runoff is collected by pipe network or by arranging outside pumping plant, effectively improves the standard of city drainage system, extenuates city
The pressure of city's waterlogging, protects urban ecological environment.
