Abstract

The invention discloses a rain collecting project. A green belt in a city is used for planting flowers and plants, and is reformed. The green belt is dug to have the depth of several meters to form a pit (1), bricks are built at the periphery (2) of the pit (1) and cement is applied, and cement is applied to the bottom (3), so that the pit (1) is waterproof; and earth which is dug out is refilled, and flowers and plants (4) are planted. When rain falls, rain is stored in the pit (1), and water cannot flow out of the pit (1) because the periphery (2) and the bottom (3) are protected by the cement. Therefore, water in the pit (1) can be used for supplying water to the flowers and plants, and an urban heat island effect can be lightened due to the evaporation of the water in the pit (1).

Description

A kind of rainwater collection project

Technical field

The present invention relates to green technology, particularly administer " urban heat land effect " method.

Background technology

" urban heat land effect ", in other words: the heat that human lives, production produce; Building structure and underlying surface characteristic cause the absorption heat many; City atmosphere pollution substrate concentration is big, has played reasons such as certain insulation effect, has caused the temperature in city to raise.

Alleviate one of the method for " urban heat land effect ", increase water body and evaporation of water amount in the city exactly, still, the city is because building and road all are brick and tile, cement works, and when raining, rainwater can't permeate the ground, and has all flowed away along sewer; On the contrary, because the finite capacity of sewer, rainwater is big a bit just can't be drained, and has caused road ponding, and vehicle and pedestrian can't walk, even ponding pours in down a chimney into house, causes any property loss.Such incident, of common occurrence in the many cities of China, comprise Beijing, these metropolis, Shanghai, newspaper, TV are reported often.

Existing collection rain method mainly is with storing in roof and the ground rainwater inflow cellar, for use when rainy.

Summary of the invention

The objective of the invention is: propose a kind of new collection rain method, both can increase the evaporated quantity of water in city, can economize on water again and water the flowers and plants trees.

The technical scheme that the present invention adopted is: have greening to bring the plantation flowers and plants on the city; Greenbelt is transformed (shown in accompanying drawing 1); It is dark that greenbelt is deep-cut some rice downwards; Become a hole (1), the hole (1) around (2) lay bricks and smear cement, cement is also smeared in bottom (3), makes hole (1) waterproof; And then with the earthen backfill of digging out, flowers, plants and trees on the kind (4).When raining, rain will be stored in the hole (1), because there is the cement protection (2), bottom (3) all around, water can not flow out outside the hole (1).

Characteristics of the present invention are: the interior ponding in hole both capable of using (1) supplies flowers, plants and trees required moisture, can alleviate " urban heat land effect " through hole (1) inner product evaporation of water again.

Points for attention: be sure not sewage is flowed into or pours in the hole (1), otherwise this hole (1) will become cesspit, the foul smell that distributes is with contaminated environment.

Fig. 5: the longitudinal sectional view that the hole of vertical shaft is arranged.

Among the figure: (1) hole; (2) around cheating; (3) bottom in hole; (4) flowers, plants and trees; (5) road surface; (6) sewer pipe; (7) pipeline; (8) edge; (9) aperture; (10) vertical shaft.

The specific embodiment

First embodiment: combine accompanying drawing 1 to describe.Greenbelt is done to transform, and it is dark that greenbelt is deep-cut some rice downwards, can reach 3-5 meters deeply, even reach more deeply more than 10 meters, forms a hole (1), around cheating (2) lay bricks and smear cement, cement is also smeared in bottom (3), makes hole (1) waterproof; And then with the earthen backfill of digging out, flowers, plants and trees on the kind (4).

Its characteristics: when raining, rain will be stored in the hole (1), because there is the cement protection (2), bottom (3) all around, water can not flow out outside the hole (1).Like this, the interior ponding in hole both capable of using (1) supplies flowers, plants and trees (4) required moisture, can alleviate " urban heat land effect " through evaporation of water again.

Second embodiment: the improvement on the basis of first embodiment.Describe in conjunction with accompanying drawing 2.The sewer pipe (6) that the house was originally had is laid a pipeline (7) more on the ground and is flowed to this greening hole (1), and when rainy, the rainwater that the sewer pipe (6) through the house flows down just flows to greening and cheats in (1).

Its characteristics: the sewer pipe (6) that makes full use of the house flow into the interior rainwater in greenbelt hole (1) and supplies flowers, plants and trees (4) required moisture, can keep that sufficient water is arranged in the hole (1); Simultaneously, the rainwater that has also reduced the house flows to ground, has increased road ponding and has been difficult for pouring in down a chimney the into possibility in house from sewer drainage, ponding.

The 3rd embodiment: the improvement on the basis of first embodiment.Describe in conjunction with accompanying drawing 3.Equally greenbelt is deep-cut hole (1), still, go across the road 0.5-1 meter in face of the edge in this hole (8) course slabstone or brick, height, the level of the edge in backfill and hole (8); There are several apertures (9) at the place on the ground at edge, let road surface (5) with cheat (1) in communicate.In addition, these apertures (9) are explained in conjunction with accompanying drawing 4.On the road surface aperture of (5) more greatly, 3-5 centimetres, aperture in (1), hole is littler, 1-2 centimetres; And aperture (9) tilts, and road surface (5) are high, and is low in the hole (1).Like this, both can prevent that the dirt in the rainwater from flowing in the hole (1), can prevent again that the soil in the hole (1) from flowing out, flow on the road.

Its characteristics: because there are several apertures (9) at place, the ground at edge, let communicate in road surface (5) and the hole (1), like this, the rainwater when raining on the road can inject through the aperture (9) at edge cheat in (1); And, during the dilutional hyponatremia of hole in (1) (exceeding on these apertures), can flow out from aperture (9) again, flow on the road surface (5), it is too much so just can not cheat (1) interior ponding, causes the flowers and plants woods to rot root.

The 4th embodiment: the improvement on the basis of first embodiment.Describe in conjunction with accompanying drawing 5.Build several vertical shafts (10) in hole (1), there are several apertures (9) at downward 0.5-1 rice, vertical shaft (10) top.Equally again with the earthen backfill of digging out, flowers, plants and trees on the kind (4).In addition, these apertures (9), more greatly, 3-5 centimetres, the aperture in the hole (1) is littler, 1-2 centimetres in the aperture of vertical shaft (10); And aperture (9) tilts, and vertical shaft (10) is located high, and is low in the hole (1).Like this, the rainwater that both can cheat high small holes in (1) flows into vertical shaft (10), can prevent that again the soil in the hole (1) from flowing in the vertical shaft (10).

Its characteristics: when rainwater in hole (1) too much the time, the aperture (9) that can pass through vertical shaft (10) top flows into vertical shaft (10), can prevent excessive rainfall and root is rotted in the root system generation of soaking flowers, plants and trees; Simultaneously, when arid, the water that also can extract vertical shaft (10) waters flowers and plants trees (4).

Second embodiment can combine with the 4th embodiment; The 3rd embodiment can combine with the 4th embodiment.
