Abstract
The invention relates to an impermeable membrane for a reservoir with exhaust function, comprising an impermeable membrane which is composed of an upper layer non-woven fabric (1), a lower-layer non-woven fabric (2) and a middle plastic membrane (3); the impermeable membrane is characterized in that: a one-way valve (4) is arranged on the impermeable membrane, the upper part of the one-way valve (4) is provided with screw threads (5), the one-way valve (4) is fixed on the impermeable membrane by a nut (6) and an upper gasket (7) and an upper gasket (8), air vent holes (9) are arranged at the bottom end of the one-way valve (4) and the side wall of the bottom end of the one-way valve (4), the upper part of the one-way valve (4) is connected with an extension pipe (10), screw threads are arranged on the extension pipe (10), so as to lead the extension pipe (10) to be screwed on the one-way valve (4); the impermeable membrane has simple structure, convenient construction and production and obvious venting decompression effect, and can greatly reduce the engineering cost and shorten the construction period.
Description
Technical field:
The invention belongs to reservoir or catch basin articles for use technical field, especially a kind of reservoir antiseepage film with exhaust plant
Background technology
China mostly is sandy soil ground along a yellow band or some plains regions, builds reservoir in these regions, and its reservoir bottom and sidewall will be laid antiseepage film and cause water to run off in a large number to prevent the seepage in the water storehouse.Some gas is difficult for discharging under film or there is organic humus the bottom of the reservior and produces biogas when laying antiseepage film.Under the pressure of reservoir water, the gas under the antiseepage film is subjected to the back-pressure actuating pressure increasing, and powerful gas pressure often causes the antiseepage film explosion water in the reservoir to leak a large amount of the loss.In recent years, for exhaust decompression, the normal employing laid stack under antiseepage film, and stack need lead to outside the reservoir dam, this pressure discharge method, and not only engineering quantity is big, also causes a large amount of equipment to drop into expense.
Summary of the invention
The objective of the invention is to overcome existing deficiency in the prior art, and a kind of simple in structure, cost is low, service-strong has exhaust plant reservoir antiseepage film is provided.The objective of the invention is to be achieved through the following technical solutions; This reservoir comprises the antiseepage film that is made of upper strata nonwoven, lower floor's nonwoven and middle plastic foil with antiseepage film, one way valve is set on antiseepage film, one way valve top is provided with screw thread, utilizes nut to add the cushions and is fixed on the antiseepage film, and the bottom of one way valve and bottom sidewall are provided with steam vent.Nonwoven is set again being provided with under the antiseepage film of one way valve.Said one way valve top is connected to extension, and extension is provided with screw thread and is tightened on the one way valve.
The present invention is simple in structure, and production and construction is convenient, and the exhaust decompression effect is obvious, and greatly reduces engineering cost, has shortened construction period.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the schematic diagram that the present invention uses in reservoir.
Among the figure, 1, the upper strata nonwoven, 2, lower floor's nonwoven, 3, middle plastic foil, 4, one way valve, 5, screw thread, 6, nut, 7, go up liner, 8, lower liner, 9, steam vent, 10, nonwoven, 11, extension, 12, reservoir, 13, the ridging layer.
The specific embodiment
With reference to accompanying drawing, the present invention will be further described: this reservoir comprises the antiseepage film that is made of upper strata nonwoven 1, lower floor's nonwoven 2 and middle plastic foil 3 with antiseepage film, one way valve 4 is set on antiseepage film, one way valve 4 tops are provided with screw thread 5, utilize nut 6 to add that liner 7 and last liner 8 are fixed on the antiseepage film, the bottom of one way valve 4 and bottom sidewall are provided with steam vent 9.Nonwoven 10 is set under the antiseepage film that is provided with one way valve 4 again.The top of said one way valve 4 is connected to extension 10, and extension 10 is provided with screw thread and is tightened on the one way valve 4.
During use, this reservoir is laid on reservoir 12 bottoms and side with antiseepage film, spinning upper extension tube 11 on one way valve 4 is established ridging layer 13 again on antiseepage film, and the mouth of pipe of extension 11 is stayed outside the ridging layer 13.During the pressure of gas produces greater than reservoir water under antiseepage film like this pressure, gas can be discharged at any time.Can prevent that antiseepage film is by explosion.
Claims (2)
1. reservoir antiseepage film with exhaust plant, comprise the antiseepage film that constitutes by upper strata nonwoven (1), lower floor's nonwoven (2) and middle plastic foil (3), it is characterized in that on antiseepage film, being provided with one way valve (4), one way valve (4) top is provided with screw thread (5), utilize nut (6) to add that liner (7) and last liner (8) are fixed on the antiseepage film, the bottom of one way valve (4) and bottom sidewall are provided with steam vent (9).
2. according to the said reservoir antiseepage film with exhaust plant of claim 1, it is characterized in that the top of said one way valve (4) is connected to extension (10), extension (10) is provided with screw thread and is tightened on the one way valve (4).
