Abstract
The utility model relates to a high strength bar-providing earth work film which belongs to the class of waterproof roll. Impregnant soaked in non-woven fabric or fibre fabric forms a rib. Plastic film sticks and covers one side face of the rib to form an earth work film which is foundation. Plastic film also sticks and covers the other side face of the rib. The impregnant in the rib is impregnant using coal tar as a raw material, polyvinylchloride as a converted material, chlorinated polyethylene as a further converted material, and attached with antiager and fillers. The earth work film has the advantages of high intensity, strong resistance to penetration, and long service life.
Description
Originally be with novel genus waterproof roll class.
For waterproof, antiseep, used the reinforcement geomembrane widely at dykes and dams, sluice, channel, roofing at present.Existing reinforcement geomembrane, it by be soaked with muscle that impregnant forms in the non-woven fabrics fiber worker fabric, in a side of muscle and cover by plastic foil and form, wherein impregnant is pitch or resembles glue.The problem of this geomembrane is: insufficient strength height, permeability resistance are strong inadequately.Application life is short.
The purpose of this utility model is: provide a kind of higher by force, the high strength reinforcement geomembrane of the strong and long service life of permeability resistance.
Technical measures of the present utility model are: with by being soaked with the muscle that impregnant forms in nonwoven or the fabric, covering the geomembrane of being made up of plastic foil in a side of muscle is the basis, has also covered plastic foil in another side of muscle.
Geomembrane of the present utility model has the good effect of the strong and long service life of intensity height, permeability resistance.
Accompanying drawing is a section structure schematic diagram of the present utility model.
Drawing explanation and embodiment are described below.2 is muscle among the figure, and muscle is soaked with impregnant and forms in nonwoven or fabric, and impregnant generally is to adopt pitch and rubber at present.A side at above-mentioned muscle 2 has covered one deck plastic foil 1, and this just constitutes the structure of existing geomembrane.The problem of this geomembrane is; Insufficient strength height, permeability resistance are strong inadequately, application life is short.The utility model is based on above-mentioned geomembrane, has also covered one deck plastic foil 3 in another side of muscle.Anti-permeability performance is significantly improved, and intensity also can increase.In order better to improve geotechnological film strength, increase the application life of geomembrane, impregnant in nonwoven or fabric, preferably adopt with coal tar be raw material, with polyvinyl chloride be material modified, be material modified, and the attached impregnant made from antiager and filler again with haloflex.The general width of this geomembrane is 2 meters, length be 12 meters practical, also can determine wide according to actual needs and long.
Claims (1)
1, a kind of high strength reinforcement geomembrane is by being soaked with the muscle that impregnant forms in nonwoven or the fabric, in a side of muscle and cover and be made up of the film formed geomembrane of plastics; It is characterized in that: another side at muscle has also covered plastic foil.
