Description
Technical field
This utility model relates to water and soil seepage control project technical field, particularly to a kind of geomembrane.
Background technology
Along with the development of the world today, in all multiple-project construction process, need to do bottom waterproof, seepage control such as water conservancy, dykes and dams, channel, draining, refuse landfill etc. and process, existing main employing geomembrane carries out waterproof, seepage control.Existing geomembrane is mainly made up of geotextiles and geomembrane, takes the technical approach of monolayer impervious barrier, is made up of high density polyethylene (HDPE), this geomembrane, and its extexine is relatively smooth, and coefficient of friction is less, it is adaptable to the engineering that place is the most smooth.If this kind of geomembrane is laid in the seepage control project that grade of side slope is bigger, geomembrane and be laid on geomembrane fill thing because of between surrounding medium interface the deficiency of frictional force easily along side slope glide, cause seepage control project failure.The most existing geomembrane structure is single; tensile strength and non-deformability are low; cause it damaged so that Seepage is inevitable due to reasons such as engineering explosion, the puncture of pointed object and scuffings during geomembrane construction or use; in addition; by being simply adhesively fixed between geotextiles and geomembrane; this design is when hard thing is more, it is impossible to guaranteeing its protected effect to geomembrane, geomembrane bulk life time is on the low side.Therefore it is badly in need of wanting a kind of tension and ability of anti-deformation to be applicable to by force various angle of inclination and constitutionally stable geomembrane to solve the problems referred to above.
Utility model content
The deficiency existed for prior art, in order to overcome the deficiencies in the prior art, it is provided that a kind of tension and ability of anti-deformation are applicable to by force various angle of inclination and constitutionally stable geomembrane, the following is concrete technical characteristic:
A kind of geomembrane, including film body and geotechnique's layer of cloth,
The both sides of described film body are provided with geotechnique's layer of cloth, and between described film body and geotechnique's layer of cloth, at least side is provided with grid layer, and grid layer is structure sheaf, enhances tensile strength and the ability of anti-deformation of geomembrane；
Described geotechnique's layer of cloth inner homogeneous is provided with crisscross reinforcement, reinforcement further enhancing tensile strength and the ability of anti-deformation of geomembrane, described reinforcement forms uniform semi-cylindrical hill on described geotechnique layer of cloth surface, projection adds the coefficient of friction on geomembrane surface so that this utility model is adapted to the use environment at multiple angle of inclination；
Described grid layer side heat is compounded on described film body, the connected mode that heat is combined enhances the structural stability of geomembrane, described grid layer opposite side is bonded on described geotechnique's layer of cloth, described film body is connected with described geotechnique's layer of cloth, and the mode being connected is conducive to the splicing of geomembrane to use in the case of ensure that geomembrane Stability Analysis of Structures.
As preferred technical scheme, the width of described film body is less than the width of geotechnique's layer of cloth, the width of described grid layer is identical with the width of described film body, formation breach is separated in the side of described geotechnique's layer of cloth and film body, opposite side forms the connection-peg corresponding with breach, and breach and connection-peg are conducive to the splicing of geomembrane to use.
As preferred technical scheme, described grid layer is formed by organizing cellosilk braiding more, and described often group cellosilk is including at least two fibers repeatly.
As preferred technical scheme, described geotechnique's layer of cloth is woven acupuncture chopped fiber geotextiles.
As preferred technical scheme, described reinforcement is entwined by cellosilk.
As preferred technical scheme, described film body material is ethylene-vinyl acetate copolymer.
Owing to have employed technique scheme, a kind of geomembrane, the geotechnological layer of cloth of outer surface is provided with the semi-cylindrical hill being made up of reinforcement, coefficient of friction increases, make geomembrane be applicable to the place at various angle of inclination, thus solve geomembrane and the thing that fills that is laid on geomembrane glides along side slope because of what deficiency because of frictional force between surrounding medium interface caused；This utility model geomembrane various structures simultaneously; tensile strength and non-deformability are high; the structure of grid layer and geotechnique's layer of cloth can effectively alleviate geomembrane construction or during using owing to the reasons such as engineering explosion, the puncture of pointed object and scuffing cause it damaged so that the problem of seepage; in addition; connected mode between geotextiles, geomembrane and grid layer, it can be ensured that it improves geomembrane bulk life time to the protected effect of geomembrane.
