Description

A kind of Rain Garden
Technical field
The utility model relates to a kind of garden, is specifically related to a kind of Rain Garden.
Background technology
Plant in garden can utilize rainwater to irrigate, and can economize on resources, environmental protection.But garden of the prior art is not considered when designing and is maximizedly utilized rainwater resource, and the later stage needs manpower or equipment to irrigate again.
Utility model content
The purpose of this utility model is to provide a kind of Rain Garden, by oozing recharge of groundwater under rainwater delay and reduce heavy rain surface flow flood peak, and can also by process decreasing pollution such as absorption, degradeds.
For solving the problems of the technologies described above, the technical scheme that the utility model provides is:
A kind of Rain Garden, comprise rainwater-collecting mouth, shelves mill weir, plantation soil layer, pervious layer and sidewalk, described rainwater-collecting mouth is again as overfall, and described rainwater-collecting mouth is arranged on the lower recess on ground, around described rainwater-collecting mouth, be equipped with cobble as overfall; Rain Garden surface layer for plantation soil layer, plantation soil layer below region be pervious layer; Be provided with rainwater collection pool in described pervious layer, described rainwater collection pool is connected with rainwater-collecting mouth by rainwater collection collector, and described rainwater collection collector is perforated pipe; Described sidewalk is provided with drain hole, and described drain hole is communicated with rainwater collection pool; Also comprise hydrolase pond, rainwater collection pool top is located in described hydrolase pond, passes through pipeline communication with rainwater collection pool.
Described pervious layer is layer of gravel.
Also plant around described rainwater-collecting mouth and be implanted with hygrophyte.
In described Rain Garden, be provided with retaining well, described retaining well is arranged on overfall side, is connected with overfall.
Described planting soil layer depth is 20cm, and the described pervious layer degree of depth is 30cm, the downward recessed 5cm-25cm of lower recess on described ground.
It is ventilation anti-seepage layer of sand below pervious layer.Add ventilation anti-seepage layer of sand at the bottom of Rain Garden, solve rotten of existing Rain Garden plant, problem that survival rate is low.
Described side, rainwater collection pool lower end is provided with discharge culvert, and the outlet of discharge culvert is communicated with road municipal administration storm sewer and arranges.
Beneficial effect:
The lowered zones of Rain Garden of the present utility model in Garden Greenland, is covered by ground quilt, hygrophyte etc., by oozing recharge of groundwater under rainwater delay and reduce heavy rain surface flow flood peak, and can also by process decreasing pollution such as absorption, degradeds.Wherein shallow hole part can accumulate certain rainwater, delays the rainwater catchment time, and planting soil and pervious layer can increase rainwater infiltration, alleviates surface pond phenomenon.The rainwater of accumulation can supply plant and utilize, and reduces the duty in greenery patches.
Rainwater collection pool is also communicated with hydrolase pond, and larger molecular organics in mud can be resolved into rapidly the small organic molecule be convenient to antimicrobial absorbent and utilized by hydrolase, stimulates indigenous microorganism growth and breeding, enhancement microbiological decomposition function; The toxic compounds such as rapid decomposition ammonia nitrogen, nitrite, hydrogen sulfide.
Accompanying drawing explanation
Fig. 1: the structural representation of Rain Garden of the present utility model.
Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described in further detail.
A kind of Rain Garden, comprise rainwater-collecting mouth 1, shelves mill weir 2, plantation soil layer 3, pervious layer 4 and sidewalk 5, described rainwater-collecting mouth 1 is again as overfall, and described rainwater-collecting mouth 1 is arranged on the lower recess on ground, is equipped with cobble as overfall 2 around described rainwater-collecting mouth 1; Being plantation soil layer 3 at the surface layer of Rain Garden, is pervious layer 4 at plantation soil layer 3 with lower area; Be provided with rainwater collection pool 6 in described pervious layer 4, described rainwater collection pool 6 is connected with rainwater-collecting mouth 1 by rainwater collection collector, and described rainwater collection collector is perforated pipe; Described sidewalk is provided with drain hole, and described drain hole is communicated with rainwater collection pool; Also comprise hydrolase pond 7, rainwater collection pool 6 top is located in described hydrolase pond 7, passes through pipeline communication with rainwater collection pool 6.Described pervious layer 4 is layer of gravel.Also plant around described rainwater-collecting mouth and be implanted with hygrophyte 8.In described Rain Garden, be provided with retaining well 9, described retaining well 9 is arranged on overfall side, is connected with overfall.Described plantation soil layer 3 degree of depth is 20cm, and described pervious layer 4 degree of depth is 30cm, the downward recessed 5cm-25cm of lower recess on described ground.It is ventilation anti-seepage layer of sand 10 below pervious layer.Described side, rainwater collection pool lower end is provided with discharge culvert, and the outlet of discharge culvert is communicated with road municipal administration storm sewer and arranges.
The above; it is only preferred embodiment of the present utility model; not any pro forma restriction is done to the utility model; any those skilled in the art; do not departing within the scope of technical solutions of the utility model; according to technical spirit of the present utility model, any simple amendment that above embodiment is done, equivalently replace and improve, within the protection domain all still belonging to technical solutions of the utility model.
