Abstract
The utility model relates to an impermeable film with an exhaust device used for a reservoir, which comprises an upper layer of non-woven fabrics (1), a lower layer of non-woven fabrics (2) and an intermediate plastic membrane (3), and is characterized in that a non-return valve (4) is arranged on the impermeable film, threads (5) are formed at the upper part of the non-return valve (4) and is fixed on the impermeable film via a nut (6), a gasket (7) and an upper gasket (8), exhaust holes (9) are formed at the bottom and the side wall of the bottom of the non-return valve (4), an extending pipe (10) is connected to the upper part of the non-return valve (4), and the extending pipe (10) with threads formed thereon is tightly screwed on the non-return valve (4). The utility model has the advantages of simple structure, convenient production and construction, and remarkable effect of exhaustion and pressure reduction, thereby greatly reducing the engineering cost, and shortening the construction period.
Description
Technical field:
The utility model 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 purpose of this utility model 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 purpose of this utility model 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 utility model 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 utility model;
Fig. 2 is the schematic diagram that the utility model 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 utility model is described further: 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).
