Abstract
A greenhouse water storage device comprises a water tank and a dike arranged on the water tank, wherein, the bottom and the walls of the water tank are covered with waterproof soil engineering films; a plurality of small holes filled with fines stones and crude sands are formed at the lower parts of the soil engineering films at the bottom of the tank; a collecting well is arranged outside the water tank and used for storing underground seepage water; and water pipes are arranged on the bottom parts of the small holes and communicated with the collecting well. The utility model has the advantages that the greenhouse water storage device reduces bubble pressure on the waterproof soil engineering film through the small holes filled with the fines stones and crude sands and formed on the bottom part of the water tank, collects ground water to the bottom part of the small holes and leads the water to the collecting well through the water pipes; the waterproof soil engineering film can be prevented from destroyed by ground water; the utility model has the advantages of simple structure, low cost and high usability; and the device can storage extra water from ordinary irrigation.
Description
Technical field
The utility model belongs to rainwater and stores technical field, relates to a kind of greenhouse water-storing device.
Background technology
In the greenhouse system, in order to make full use of natural resources---rainwater, then generally on the large greenhouse limit, build reservoir, to collect the rainwater in the greenhouse roofing and the reservoir sky.Rainwater is scrubbed etc. through promptly can be used for the irrigation in the greenhouse after the water treatment, can save the greenhouse use cost.
Reservoir generally is to dig a bottom surface on the ground at earth to be lower than about 1 meter on ground for saving cost, and dykes and dams are above the ground level about 1 meter, and the rectangle mud pit on slope at 45, and simultaneously with rammed earth, the PE geomembrane of waterproof is spread on inner surface in the mud pit.Because the mud pit is dug when being lower than 1 meter on ground deeply, often there is underground water to ooze out, when weather is hot, also has bubble and emerge, this not only can reduce the retaining volume of reservoir, also the geomembrane top might be split, and can cause striding of reservoir to collapse when serious.
The utility model content
The purpose of this utility model is to provide a kind of greenhouse water-storing device, and is floating easily with the waterproofing geomembrane that overcomes existing reservoir inside, pushed up and splits the defective of collapsing easily with reservoir.
The problem that the utility model solved can realize by the following technical solutions:
A kind of greenhouse water-storing device comprises the pond, is arranged on the dykes and dams on the pond, it is characterized in that: at the bottom of the pond, described pond and be coated with waterproofing geomembrane on the pool wall, geomembrane bottom at the bottom of the pond is provided with a plurality of apertures that microlith, coarse sand are housed.
Outside, described pond is provided with the collecting well that is used for storing underground infiltration, and the bottom of described aperture is provided with the water pipe that is connected with collecting well.
In described aperture, coarse sand comes the top of microlith.
The top of described dykes and dams is provided with notch, and described waterproofing geomembrane covers on the interior pool wall of the whole and dykes and dams at the bottom of the pond.
Be coated with the ground cloth of support, reinforce dikes and dams effect on the waterproofing geomembrane in described pond, described ground cloth covers on inside and outside two pool walls of dykes and dams, has been coated with the fragment of brick of fixation on the two ends of ground cloth.
Beneficial effect: a kind of greenhouse of the utility model water-storing device, only by be provided with a plurality of apertures that microlith, coarse sand are housed in basin bottom, not only reduced the pressure of bubble to waterproofing geomembrane, also underground water is accumulated in the aperture bottom, and these water are caused collecting well by water pipe, and can prevent that waterproofing geomembrane from being split by the underground water top, simple in structure, cost is low, and usability is strong.And the device that can also store as unnecessary water when irrigating at ordinary times.
Description of drawings
Fig. 1 is the cross-sectional view of a kind of greenhouse of the utility model water-storing device.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
With reference to Fig. 1, at the bottom of the pond in described pond 1 and on the interior pool wall 3, be coated with waterproofing geomembrane 4, waterproofing geomembrane 4 continues up to notch 9 places at dykes and dams top, and the water of inside, pond just can not be seeped into underground like this; Bottom from interior pool wall 3, on waterproofing geomembrane 4, continue up to the outer pool wall and the ground line intersection of dykes and dams 2, be coated with ground cloth 5, be coated with fragment of brick 6 on the two ends of ground cloth 5, ground cloth 5 can make dykes and dams 2 become more firm, prevents that it from collapsing, fragment of brick 6 can make ground cloth 5 cover more securely on the dykes and dams 2, improves the anti-pressure ability of dykes and dams 2.
At the bottom of the pond, be provided with below the waterproofing geomembrane 4 microlith, rough sand aperture 8 are housed, microlith is in the bottom of rough sand, the microlith that aperture is 8 li, rough sand, can prevent that underground bubble rises to waterproofing geomembrane 4 from aperture 8 bottoms when it is warm, thereby reduced the pressure of underground water to waterproofing geomembrane 4, microlith rough sand can also be drawn aperture 8 underground water on every side simultaneously, and waterproofing geomembrane 4 is split by the top when preventing the groundwater table rising; Under gravitational effect, long-time after, the underground water of drawing in microlith, the rough sand can accumulate in the bottom of aperture, and flows in the collecting well 7 by the strong water pipe 10 (as bellows) of anti-pressure ability, collecting well 7 interior water can be extracted out as required at any time.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the manual just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
