Description
Technical Field
The utility model relates to the technical field of geotextiles, in particular to a geotextile.
Background
Geotextiles are also called woven geotextiles, are generally applied to reinforcement and reinforcement of geotechnical engineering projects (such as water and soil conservation and ecological restoration projects of river courses and embankments), have plane isolation and protection functions, and are materials commonly used in modern ecological projects. Geotextile in the related prior art is generally woven by single flat wires, and because the hardness of the flat wires is high, the woven geotextile has larger pores at the cross-shaped part (namely the cross-bending part of the flat wires) and sand filling is easy to exude from the pores.
In view of the above, there is a need in the art for geotextiles that are less porous, are capable of preventing the seepage of sandy soil fillers, and have excellent tensile strength as a result of braiding.
Disclosure of Invention
The utility model aims to provide geotextile which can prevent sand filling from exuding, has higher tensile strength and is not easy to damage.
In order to achieve the above object, the present utility model provides a geotextile formed by braiding a plurality of first filaments and a plurality of second filaments, each of the first filaments including a plurality of filaments, and the first filaments not being twisted.
Specifically, the width of the second filaments is 1mm to 3mm; each strand of the first filaments comprises at least 50 filaments, the filaments having a diameter of less than 0.1mm.
Specifically, the width of the second filaments is 1.5mm to 2.5mm; each strand of the first filaments comprises at least 100 filaments, the filaments having a diameter of less than 0.05mm.
Specifically, the geotextile comprises a plurality of the first filaments woven in a first direction and a plurality of the second filaments woven in a second direction; or the geotextile comprises a plurality of the first filaments and a plurality of the second filaments each woven in a first direction and a plurality of the second filaments woven in a second direction; or the geotextile comprises a plurality of the first filaments and a plurality of the second filaments each woven in a first direction and a plurality of the first filaments and a plurality of the second filaments each woven in a second direction, wherein the first direction and the second direction are perpendicular to each other.
Specifically, the number ratio between the plurality of strands of the first filaments woven in the first direction and the plurality of strands of the second filaments woven in the first direction is 1 to 1; the ratio of the number of the plurality of first filaments woven in the second direction to the number of the plurality of second filaments woven in the second direction is 1 to 1.
Specifically, the ratio of the elongation of the first filaments to the elongation of the second filaments is 0.8 or more and 1.2 or less.
Specifically, the ratio of the elongation of the first filaments to the elongation of the second filaments is 0.95 or more and 1.05 or less.
In particular, the first and second filaments are both made of the same material.
In particular, the same material is plastic.
Specifically, the plastic is one of polyester, polypropylene and nylon.
The geotextile of the utility model can obtain the following technical effects:
Each first filament can function well to fill the gaps between the second filaments because each first filament includes more than a certain number of filaments, and the filaments have smaller diameters and are not twisted, and a filter structure composed of dense filaments can be formed between two second filaments. The structural gap is smaller than the diameter of sediment, so that water can smoothly pass through the structure to block the sediment from passing through, if twisting is performed, the diameter of each strand of first yarn is uneven, and the thin yarns cannot be sufficiently dispersed, so that the gaps between part of the first yarns and the second yarns are too large to block the sediment from passing through.
The second filaments with certain width in the geotextile of the present utility model can improve the tensile strength and durability of the geotextile as a whole, and each filament can be uniformly stressed in the extending direction thereof as each first filament is not twisted, thereby improving the tensile strength of the geotextile as a whole.
The geotextile of the utility model has the similar elongation between the first silk and the second silk, so that the whole tensile strength of the geotextile is higher. If the elongation difference is large, stress concentration is easily generated at the plastic wires with small elongation when the geotextile is stretched, so that the whole tensile strength of the geotextile is reduced.
The geotextile can more effectively prevent sand and soil fillers from exuding in the application of hydraulic engineering, and has good air permeability, water permeability, tensile strength and durability.
Additional features and advantages of the utility model will be set forth in the detailed description which follows.
