Abstract
The utility model relates to a nonwoven geotextile, which is mainly used for maintaining road surfaces, and is characterized in that: the geotextile employs a three-layer structure, a middle layer is a polyester short fiber layer (1), an upper surface layer and a lower surface layer are polypropylene long fiber layers (2), and the three layers are combined tightly. The utility model has the advantages of the polyester short fiber layer, has enhanced tensile strength and resistance to deformability due to the existence of the polypropylene long fiber layers, and has low cost on the basis of the same thickness.
Description
Technical field
The utility model relates to a kind of nonwoven, relates in particular to a kind of non-woven geotextile, is mainly used in the maintenance of highway pavement.
Background technology
The maintenance of highway pavement is used terylene short fiber acupuncture geotextiles usually with geotextiles.Its effect is:
1: isolate
Utilize terylene short fiber acupuncture geotextiles that the constructional materials (as the soil body and the grains of sand, the soil body and concrete etc.) with different physical properties (particle size, distribution, denseness and density etc.) is isolated.Two or more storerooms are not run off, do not mix, keep the overall structure and the function of material, structure are carried, and the ability of holding is strengthened.
2: filter
When water flows into the coarse fodder soil layer by the fines soil layer, utilize terylene short fiber acupuncture geotextiles air permeability and good and water permeability, current are passed through, and current-carrying soil particle effectively, fine sand, gravelstone material etc., stable with the engineering that conserves water and soil.
3: draining
Terylene short fiber acupuncture geotextiles has good water guide performance, and it can form drainage channel by inside soil body, and unnecessary liquids and gases in the soil structures are effluxed.
4: reinforcement
Utilize terylene short fiber acupuncture geotextiles to strengthen the tensile strength and the non-deformability of the soil body, the stability of enhancing building structure is to improve soil body quality.
But its tensile strength of terylene short fiber acupuncture geotextiles and non-deformability are relatively poor, and compared to nonwoven polypropylene fabric, its cost is higher.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of tensile strength and non-deformability strong, lower-cost non-woven geotextile.
The purpose of this utility model is achieved in that a kind of non-woven geotextile, it is characterized by: described geotextiles is a three layer construction, and its intermediate layer is the terylene short fiber layer, and upper and lower top layer is the long fine layer of polypropylene fibre,, described three layer construction closely is combined with each other.
Compared with prior art, the beneficial effects of the utility model are:
The utility model non-woven geotextile, it had both had the advantage of terylene short fiber layer, and because the existence of the long fine layer of polypropylene fibre has improved its tensile strength and non-deformability, on the basis of condition of equivalent thickness, its cost is low again.
Description of drawings
Fig. 1 is the section structure schematic diagram of the utility model non-woven geotextile.
Wherein:
Terylene short fiber layer 1, the long fine layer 2 of polypropylene fibre.
The specific embodiment
Referring to Fig. 1, a kind of non-woven geotextile that the utility model relates to is three layer construction, and the intermediate layer is a terylene short fiber layer 1, and upper and lower top layer is the long fine layer 2 of polypropylene fibre, and three layer construction is combined with each other by needling process.
Claims (1)
1. non-woven geotextile, it is characterized by: described geotextiles is a three layer construction, and its intermediate layer is terylene short fiber layer (1), and upper and lower top layer is the long fine layer of polypropylene fibre (2), and described three layer construction closely is combined with each other.
