Water-saving roof planting pond
The utility model relates to a kind of planting bed, relates in particular to a kind of water-saving roof planting pond, belongs to garden engineering technology neck.
Along with urban population sharply expands, but reduce year by year in the greenery patches of answering in contrast.The environmental deterioration grievous injury that various pollutions, tropical island effect etc. cause the physical and mental health of urban human.When the urban ground that can be used to afforest is less and less, people start to recognize the 5th face---roof of building.Utilize plant characteristic and its distinctive environment regulatory function alleviate city underlying surface harden urban heat land effect that phenomenon brings, alleviate a series of "urban disease"s that affect urban sustainable development such as municipal pollution, adverse weather.Therefore,, in the city of an inch of land is an inch of gold, roof greening is imperative.
Existing roof planting device generally comprises pond body, can planting plants in the body of pond, beautify the environment, and purify air; But roof planting plant, by manpower, irrigate to a great extent, waste time and energy.The easy ponding of excessive rainfall on rainy day, causes plant root to rot; Meanwhile, because roof planting soil is generally thinner, a little less than water-holding capacity, as the long period does not have rainwater, easily cause again the arid of roof plants, cause plant dead or malnutritive, affect the effect of roof greening.Roof has sufficient sunlight and sufficient rainwater resource, if can, by rainwater-collecting for irrigating the plant of roof planting, will greatly reduce the manpower maintenance cost of the artificial greening in roof.
Utility model content
The utility model, in order to overcome the deficiencies in the prior art, provides a kind of water-saving roof planting pond without manual operation, realizes whose supply self-loopa in roof planting pond.
For this reason, the utility model is by the following technical solutions:
A water-saving roof planting pond, comprises pond body, in the body of described pond, is provided with a header tank, and header tank has separated irrigation district and ponding holds district, and irrigation district holds district with ponding and is communicated with by siphon pipe; Bottom-up stopping area, aquifer, the nutrient planting layer of being provided with successively of pond body, also comprise a water-supply-pipe, water-supply-pipe has and is positioned at the body of aquifer, the water inlet being connected with bottom, irrigation district and holds with ponding the water side that district is connected, the water inlet of water-supply-pipe is higher than water side, in water-supply-pipe, be filled with rubble, water-supply-pipe is provided with apopore.The utility model by irrigation district is set, ponding holds district and water-supply-pipe, utilize to irrigate and to go to collect and storing rainwater, and by water-supply-pipe, plant is supplied water, in the body of pond during excessive rainfall, can rainwater be introduced to ponding by water-supply-pipe and hold district, prevent the generation of rotten root; Irrigation district holds district with ponding and is connected by siphon pipe, has guaranteed that irrigation district and ponding hold the water-head existing between district; Automatic irrigation and the anti-ponding of realizing roof plants, without manual operation, time saving and energy saving, also saved water resource.
Further, described header tank and pond body are structure as a whole.It is more firmly stable that this arranges structure, and to manufacture simple, convenient simultaneously.
Further, described body is continuous U-shaped, arranging in interior week along pond body in aquifer.This setting makes water-supply-pipe water outlet more even, more abundant to the irrigation of plant.
Further, described internal diameter of tube body is 5cm, and described rubble diameter is 0.5cm.This size is conducive to settle rubble in body, can not affect outlet effect simultaneously.
Further, described irrigation district and ponding hold district and form by dividing plate is set in header tank.This is simple in structure, and water capacity is larger.
In sum, the utility model can be realized the catchmenting of roof planting, automatic irrigation and anti-ponding, has greatly reduced intensity and the frequency of artificial interference, arranges simple, easy to use.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is section plan of the present utility model;
Fig. 3 be in Fig. 2 A-A to cut-away view.
In order to make those skilled in the art person better understand the utility model scheme, below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out to clear, complete description.
As Figure 1-3, a kind of water-saving roof planting pond, comprise pond body 1, in described pond body 1, be provided with a header tank 2, header tank 2 has separated irrigation district 3 and ponding holds district 4, irrigation district 3 and ponding hold district 4 and are communicated with by siphon pipe 8, and moisture can be carried to soil in irrigation district, and irrigation district can hold moisture unnecessary in soil; Bottom-up stopping area 11, aquifer 12, the nutrient planting layer 13 of being provided with successively of pond body 1, described stopping area 11 is for stopping net, and stopping that online surface arranges layer of copper alloy film, for stopping that plant root grows downwards, described aquifer 12 is stone sand bed, the runner that is conducive to moisture, irrigates more fully, and water guide is effective, rainy day is easily guided to ponding by unnecessary water and holds district, and nutrient planting layer, the rotten cauline leaf of lower position plant, and top is soil; The water-supply-pipe 5 that also comprises a circle, water-supply-pipe 5 is for delivery of moisture and plant irrigating, water-supply-pipe 5 has and is positioned at the body 51 of aquifer 12, the water inlet 52 being connected with 3 bottoms, irrigation district and holds with ponding the water side 53 that district 4 is connected, the two ends of body 51 connect respectively water inlet 52 and water side 53, the water inlet 52 of water-supply-pipe 5 is a little more than water side 53, in water-supply-pipe 5, be filled with rubble 7, water-supply-pipe 5 is provided with apopore.
Described water inlet 52 is arranged at 3 bottoms, irrigation district, can carry out automatic irrigation moisturizing by hydraulic pressure like this, also can make full use of the water in irrigation district; For fear of lasting moisturizing, cause soil excessively to wet and cause rotten of plant, be also provided with the amount that water control valve is controlled moisturizing, further reach water saving object.
Described header tank 2 is structure as a whole with pond body 1, certainly in other embodiments, also header tank 2 and pond body 1 can be arranged to Split type structure; Described irrigation district 3 and ponding hold district 4 by forming at the interior dividing plate that arranges of header tank 2, and also in interior two inner sleeves that arrange of header tank 2, one to be 3, one of irrigation districts hold district 4 for ponding.
The shape of described body 51 can also have multiple, conventionally body 51 is arranged to a large U-shaped, and in the present embodiment, described body 51 is continuous U-shaped setting in aquifer 12.
The internal diameter of body 5 is the more than 8 times of rubble 7 diameters, and water delivery is effective, and in the present embodiment, in order to make water delivery effect reach best, described body 51 internal diameters are 5cm, and described rubble 7 diameters are 0.5cm.
Obviously, described embodiment is only a part of embodiment of the present utility model, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all should belong to the scope of the utility model protection.
