Abstract
A self-adapting deflating geomembrane mainly resolves the problem that a common geomembrane is easy to be damaged through 'blowout' and comprises the geomembrane, wherein a one-way deflating device is inserted on the geomembrane, a deflating pipe and a rubber pipe are arranged on the one-way deflating device, the rubber pipe is sleeved on an air outlet end of the deflating pipe, a plurality of one-way deflating devices are arranged in a proper distance range, and the thickness of the rubber pipe can be arranged according to water levels and soil conditions. The one-way deflating device has simple structure and low cost, can guarantee air accumulated on the bottom of the geomembrane to be discharged to a reservoir through a one-way deflating valve, and can prevent blowout phenomenon of the geomembrane, thereby prolonging the service life of the geomembrane and avoiding water seepage of the reservoir. Moreover, the one-way deflating device is low in cost and simple in construction and has no influence on the laying of the geomembrane.
Description
Technical field
The utility model relates to a kind of geomembrane, specifically a kind of reservoir seepage-proofing, the anti-geomembrane that breaks.
Background technology
In recent years, geomembrane is as a kind of novel impervious material, be widely used in the earth and rockfill dam seepage control project, particularly experienced after the Changjiang river in 1998, the Song Hua River great flood, Ministry of Water Resources has issued that relevant geosynthetics is used and the industry standard of test, test, the design and construction of geomembrane are had regulations to abide by, greatly promoted its application in hydraulic engineering, traffic engineering and construction work.In recent years along with geomembrane in hydraulic engineering reservoir reinforcement engineering and the application in the Wall in Plain Reservoir, tailing dam application in engineering in refuse landfill in the Environmental Engineering and the mineral products department, also expose some problems gradually, for example the geomembrane large tracts of land is layed in Wall in Plain Reservoir or other storehouses and (comprises mine tailing storehouse or refuse landfill), because phreatic effect or other organic chemical reactions, inevitably will be in the reservoir area underground generation gas, accumulation along with gas, will be in the some positions or the accumulation of some position of geomembrane, when running up to a certain degree, bubble makes, be easy to make the geomembrane explosion, be commonly called as in this phenomenon engineering and be " blowing out ".Generation for fear of " blowing out " phenomenon, and prevent the seepage of reservoir area, " nanometer expansive soil waterproof blanket " or " nanoclay waterproof blanket " have been developed in the engineering, waterproof blanket thickness is generally between 0.5mm-1.0mm, after " blowing out ", utilize the self-healing function of nanometer expansive soil or nanoclay to repair geomembrane.But because the quantity of anti-rice material seldom, nanometer expansive soil or nanoclay often run off in the water of storehouse with air-flow, so repairing effect is unsatisfactory, and construction costs is very expensive.
The utility model content
At the problem of existing reservoir with geomembrane bottom easy " blowing out " destruction; the utility model provides a kind of novel being suitable for to be laid on the geomembrane of reservoir bottom; it by be provided with on the geomembrane a kind of can be according to air pressure size automatic air eliminator under the film; to solve " blowing out " problem of large tracts of land antiseepage; thereby the protection geomembrane can not broken through by gas, increases the application life of geomembrane, guarantees that reservoir does not seep water; cost is low, is suitable for use of large-scale production.
The concrete technical scheme that the utility model adopts is: a kind of self adaptation venting geomembrane, comprise geomembrane, it is characterized in that described geomembrane is inserted with the single-way gas-discharge device, the single-way gas-discharge device is provided with bleeder pipe and rubber tube, and rubber sleeve is located at the nose end of giving vent to anger of bleeder pipe.Can on geomembrane, certain at interval distance be provided with, as a single-way gas-discharge device being set every 1.0 meters or 2.0 meters, put aside when the gas under the geomembrane under the situation of certain pressure, gas can be by the upwards venting of single-way gas-discharge device, to reduce the damage of gas to geomembrane.
Described bleeder pipe is provided with first bealock and second bealock, first bealock is located at the bleeder pipe middle part, second bealock is located at the first bealock top, the venthole of described bleeder pipe is located at the second bealock top, the inlet end of described bleeder pipe is provided with at least one air inlet, by after first bealock be set guarantee that bleeder pipe plugs geomembrane, geomembrane is stuck on first bealock, because the viscoelastic properties of geomembrane, geomembrane will tightly surround first bealock, increase the steadiness of bleeder pipe, by second bealock can be better fixing rubber tube, prevent that rubber tube breaks away from.
Described bleeder pipe is fixed on the geomembrane by nut, by the fixing bleeder pipe of nut, can pad be set at nut and geomembrane interface, guarantees that the connectivity of bleeder pipe and geomembrane is better.
The beneficial effects of the utility model are: this self adaptation venting geomembrane is by being provided with a plurality of single-way gas-discharge devices in suitable distance range, and the thickness of rubber tube is set according to water level and soil regime, this single-way gas-discharge apparatus structure is simple, the gas that has guaranteed geomembrane bottom savings can be discharged in the reservoir by the single-way gas-discharge valve, preventing that geomembrane from producing blows out phenomenon, both increased the application life of geomembrane, can prevent that again reservoir from having water leakage, cost is low, construction is simple, does not influence the laying of geomembrane.
