Description
Technical field
The utility model belongs to engineering construction material technology field, particularly relates to a kind of geotechnique of the oil-stain-preventing type for engineering construction pad.
Background technology
The environmental problem causing due to Oil spills is reported in media often, and the main method of existing oil-stain-preventing seepage is the rigidity antiseepage of being combined with cement with geomembrane, once this mode seepage just thoroughly lost efficacy, oil plant occurs and reveal.The method of processing oil plant leakage is that emergency is processed, and from occurring that greasy dirt is leaked to have administered, needs the regular hour, has produced during this period serious environmental pollution.
Sodium bentonite geotechnique pad is widely used in the fields such as municipal administration, tunnel, water conservancy, refuse landfill, mine because of features such as its excellent barrier performance, easy constructions.Common bentonite geotechnique cushion function is comparatively single, just moisture is had to good absorption and control ability, and oil is mainly the organic mixture that aromatic hydrocarbon forms by alkane, cycloalkane, a little less than conventional sodium bentonite geotechnique pad absorption greasy dirt ability, its application is restricted; Meanwhile, sodium bentonite geotechnique pad unit are grammes per square metre is greater than 4500g conventionally, and larger grammes per square metre is unfavorable for transportation and construction.
Summary of the invention
In view of this, the utility model embodiment provides a kind of oil-stain-preventing type geotechnique pad, and main purpose is that the existing geotechnique's pad of solution oil-stain-preventing pollutant performance is poor, is not easy to the problem of transportation and construction.
In order to solve the problems of the technologies described above, the utility model has adopted following technical scheme:
On the one hand, the utility model embodiment provides a kind of oil-stain-preventing type geotechnique pad, and it comprises:
Nonwoven layer, geotextile layer and organobentonite layer;
Organobentonite layer is between nonwoven layer and geotextile layer;
The fiber of nonwoven layer, through bentonite and geotextile layer, connects nonwoven layer and geotextile layer.
Oil-stain-preventing type geotechnique pad as above, further, described geotextile layer is nonwoven or woven cloth.
Oil-stain-preventing type geotechnique pad as above, further, described nonwoven is polypropylene short fiber nonwoven; Described woven cloth is polypropylene flat-filament woven cloth.
Oil-stain-preventing type geotechnique pad as above, further, every square metre of described bentonite weight is at 1000g～1400g; The weight of every square metre of described nonwoven layer is at 200g～240g; The weight of every square metre of described geotextile layer is at 110g～150g.
Oil-stain-preventing type geotechnique pad as above, further, the fracture strength of described geotechnique's pad is greater than 10kN/m, and percentage elongation is greater than 10%, and peel strength is greater than 65N/10cm.
Compared with prior art, the beneficial effects of the utility model are:
Organobentonite layer is fixed between nonwoven layer and geotextile layer, makes geotechnique's pad of preparation possess waterproof, two kinds of functions of oil-stain-preventing simultaneously.In addition, the fiber of nonwoven layer passes bentonite and geotextile layer, and is fixed on geotextile layer, makes the standby peel strength preferably of geotechnological spacer.
Meeting (adsorbable >=14 of every square meter geotechnique pad under oil-stain-preventing requirement prerequisite, 000 milliliter of gasoline), the Weight control that every square metre of oil-stain-preventing type geotechnique is padded is between 1310g～1790g, compare (every weight per square meter is greater than 4500g conventionally) with common bentonite geotechnique pad, the oil-stain-preventing type geotechnique pad weight of the utility model embodiment is lighter, is convenient to transportation and construction.
The preparation method of oil-stain-preventing type geotechnique pad, comprise: organobentonite uniform spreading is located on geotextile layer, on organobentonite, use non-textile mulch, then acupuncture utilizes the fiber of nonwoven layer that organobentonite is fixed between nonwoven layer and geotextile layer.
Accompanying drawing explanation
Accompanying drawing described herein is used to provide further understanding of the present utility model, forms the application's a part, and schematic description and description of the present utility model is used for explaining the utility model, does not form improper restriction of the present utility model.In the accompanying drawings:
A kind of oil-stain-preventing type geotechnique pad schematic diagram that Fig. 1 provides for the utility model embodiment.
In accompanying drawing, the list of parts of each label representative is as follows:
1, nonwoven layer, 2, organobentonite layer, 3, geotextile layer, 4, fiber.
The specific embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail, but not as to restriction of the present utility model.
The utility model embodiment technical problem to be solved is that existing geotechnique's pad oil-stain-preventing pollutant performance is poor, is not easy to carry.As shown in Figure 1, be a kind of oil-stain-preventing type geotechnique pad schematic diagram that the utility model embodiment provides, it comprises:
Nonwoven layer 1 is 110g/m
2polypropylene short fiber nonwoven;
