Abstract
The utility model discloses a seepage-prevention high-strength composite cover fabric for a water reservoir. The composite cover fabric is formed by a geomembrane (1) and is characterized in that an ultra-high molecular weight polyethylene fiber mesh (3) is bonded on the bottom side surface of the geomembrane (1) through a binding layer (2). Since the geomembrane is bonded with the ultra-high molecular weight polyethylene fiber mesh and the ultra-high molecular weight polyethylene fiber mesh has extremely-high tensile strength, the seepage-prevention high-strength composite cover fabric can effectively prevent seepage, has enough strength and is easy to be laid flat. The seepage problem of the water reservoir and the dam is effectively solved, the service life is increased, and the service efficiency of the water reservoir can be greatly increased.
Description
Technical field
The utility model relates to a kind of improvement of reservoir seepage-proofing material, the compound shop of specifically a kind of reservoir seepage-proofing high strength cloth.
Background technology
Reservoir is the critical facility of water conservancy industry, has the function of flood control, irrigation, generating, shipping, town and country water supply and aquaculture.Along with the development of emerging travel industry, Reservoir Area has also become important tourism resource.Obviously, the water of capacity is arranged throughout the year in construction of reservoir and the guarantee reservoir, can promote the development of local economy.But when building reservoir, prevent that the bottom of the reservior from leaking and dam leaks is a key link, it is related to the success or failure of reservoir, Limestone Mountain Areas reservoir particularly, the serious seepage of bottom of the reservior is a kind of universal phenomenon, this reservoir, do not have water once meeting arid, had a strong impact on the use value of reservoir.At present, the major measure that prevents reservoir leakage is exactly at bottom of the reservior and the inboard geomembrane of laying of dam.From anti-seepage effect, geomembrane anti-seepage will obviously be better than the antiseepage of clay bedding.In recent years, along with the continual renovation and the development of coating materials kind, construction technology is advanced further, and the geomembrane anti-seepage application is also extensive further.But at present used geomembrane be one deck structure only, during use, the bottom of the reservior be flattened, shop one deck clay leveling, as lower protective layer, spread geomembrane after, above geomembrane, repave one deck clay again and flatten, as last topping.From anti-seepage effect, geomembrane anti-seepage will obviously be better than the antiseepage of pure clay bedding.But present employed geomembrane is owing to be single layer structure, and its intensity is lower, when meeting the stone extruding, starts a leak easily, and a leak can cause large-area infiltration, has reduced the anti-seepage effect of geomembrane, has also influenced the application life of reservoir; Simultaneously, in process of deployment, because geomembrane has certain retractility, so be not easy to pave whole.
Summary of the invention
The purpose of this utility model is to provide a kind of can effective anti-seepage effect, and enough intensity is arranged again, but also pave easily whole, can effectively prevent reservoir and dam the infiltration the compound shop of a kind of reservoir seepage-proofing high strength cloth.
For reaching above purpose, the technical scheme that the utility model adopted is: this compound shop of a kind of reservoir seepage-proofing high strength cloth, constitute by geomembrane, and it is characterized in that: the bottom side of described geomembrane is gone up the ultra high molecular polyethylene fleece by the tack coat bonding.
The utility model is also implemented by following measure: the fibroreticulate mesh of described ultra high molecular polyethylene is a square hole, and its length of side is 10cm, is formed by warp-wise ultra high molecular polyethylene fiber and the fibrage of broadwise ultra high molecular polyethylene; Described ultra high molecular polyethylene fiber is a prior art, can directly buy.
This compound shop of a kind of reservoir seepage-proofing high strength cloth can comprise shop geomembrane machine, shop ultra high molecular polyethylene fleece machine and spray cementing agent machine by special equipment production, drying, and clot is standby.
The beneficial effects of the utility model are: compare with present employed geomembrane anti-seepage, one deck ultra high molecular polyethylene fleece because geomembrane has bondd, this ultra high molecular polyethylene fleece tensile strength is high, so, effective anti-seepage effect can be arranged, enough intensity is arranged again, but also even up easily pave whole, can effectively prevent a kind of reservoir seepage-proofing of reservoir and dam infiltration, and long service life can significantly improve the service efficiency of reservoir.
Description of drawings
Fig. 1, be structure elevational schematic view of the present utility model.
Fig. 2, analyse and observe enlarged diagram for structure of the present utility model cross section.
The specific embodiment
Make the utility model with reference to Fig. 1,2.This compound shop of a kind of reservoir seepage-proofing high strength cloth, constitute by geomembrane 1, it is characterized in that: the bottom side of described geomembrane 1 is gone up ultra high molecular polyethylene fleece 3 by tack coat 2 bondings, reach effective antiseepage by geomembrane 1, increase the tensile strength of geomembrane 1 by ultra high molecular polyethylene fleece 3, simultaneously, also prevent to meet stone and crush geomembrane 1, also help tension and pave whole.
As improvement of the present utility model, the mesh of described ultra high molecular polyethylene fleece 3 is a square hole, and its length of side is 10cm, is formed by warp-wise ultra high molecular polyethylene fiber 3a and broadwise ultra high molecular polyethylene fiber 3b braiding; Described ultra high molecular polyethylene fiber is a prior art, can directly buy.
This compound shop of a kind of reservoir seepage-proofing high strength cloth can comprise shop geomembrane machine, shop ultra high molecular polyethylene fleece machine and spray cementing agent machine by special equipment production, drying, and clot is standby.
Claims (2)
1. the compound shop of a reservoir seepage-proofing high strength cloth is made of geomembrane (1), it is characterized in that: the bottom side of described geomembrane (1) is by ultra high molecular polyethylene fleece (3) on tack coat (2) bonding.
2. the compound shop of a kind of reservoir seepage-proofing high strength according to claim 1 cloth, the mesh that it is characterized in that described ultra high molecular polyethylene fleece (3) is a square hole, its length of side is 10cm, is formed by warp-wise ultra high molecular polyethylene fiber (3a) and broadwise ultra high molecular polyethylene fiber (3b) braiding.
