Abstract
The invention discloses anti-skid short-fiber needle-punched geotextile which comprises a geotextile body formed by needle punching of short fibers, wherein strengthening ribs are uniformly arranged on one side surface of the geotextile body, and adopt strip-shaped structures; anti-skid protrusions are uniformly distributed on the other side surface of the geotextile body, and adopt cuboid structures with grooves; each groove adopts a frustum structure with a wide upper end and a narrow lower end. The anti-skid short-fiber needle-punched geotextile has the advantages that the structure is simple; not only is the advantage of short-fiber needle-punched non-woven geotextile fully utilized, but also the tensile strength and the deformation-resistant capability of the anti-skid short-fiber needle-punched geotextile in each direction are enhanced due to the strengthening ribs arranged on the side surface of the geotextile body; as the anti-skid protrusions are arranged on the other side surface of the geotextile body, relative sliding between the anti-skid short-fiber needle-punched geotextile and ambient media in all directions can be hindered.
Description
Technical field
The present invention relates to a kind of geotextiles, relate in particular to the chopped fiber needle-punched geotextiles of a kind of anti-slip type.
Background technology
Synthetic staple fibers needling nonwoven geotextiles is by carding after synthesising fibre shredding, utilizes thorn repeatedly to pierce through up and down for fibre web, makes the fiber set of mutually tangling become cloth. Product thickness is generally more than 1mm, and porosity is high, and permeability is large, and anti-filter drainage performance is all good, very wide in water conservancy and highway engineering application. Can also with the geomembrane formation composite that is combined with each other, provide reinforcement and protective effect to film.
Traditional conventional geotextiles structure is single, and tensile strength and non-deformability are low, and in use geotextiles medium easily and around it is because of the little relative sliding of frictional force. In order to improve intensity and the non-skid property of geotextiles, technical staff arranges respectively reinforcement and tread plate in geotextiles both sides. But the tread plate weak effect of this geotextiles, and in use procedure, only there is the skidproof effect to single direction.
Summary of the invention
The object of the invention is to overcome the above-mentioned problems in the prior art, provide a kind of anti-slip type chopped fiber needle-punched geotextiles.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
The chopped fiber needle-punched geotextiles of a kind of anti-slip type, comprise the chopped fiber needle-punched geotextiles body forming, one side surface of described geotextiles body is equipped with reinforcement, described reinforcement is strip structure, the opposite side surface of described geotextiles body is evenly equipped with anti-skidding projection, described anti-skidding projection is the rectangular structure with groove, and described groove is frustum structure wide at the top and narrow at the bottom.
Further, the lower end of described reinforcement caves inward and is formed with triangular prism connected in star, makes reinforcement also have good skidproof effect.
Further, described reinforcement is made up of high-density polyethylene material.
Further, described reinforcement equates with the height of anti-skidding projection, and interlaced distribution, is convenient to stack transport.
The invention has the beneficial effects as follows:
The present invention is simple in structure, when making full use of synthetic staple fibers needling nonwoven geotextiles advantage, on one side surface, is provided with reinforcement, has increased tensile strength and the non-deformability of short fiber geotextiles all directions; The anti-skidding projection being provided with on its opposite side surface, utilizes the structure of anti-skidding projection to hinder the relative sliding of short fiber geotextiles and its surrounding medium all directions.
Brief description of the drawings
Fig. 1 is the structural representation that the present invention is positioned at anti-skidding convex side;
Fig. 2 is the structural representation that the present invention is positioned at reinforcement side;
Fig. 3 is side view of the present invention.
Detailed description of the invention
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.
The chopped fiber needle-punched geotextiles of anti-slip type described in the present embodiment, as shown in Figures 1 to 3, comprise the chopped fiber needle-punched geotextiles body 1 forming, one side surface of described geotextiles body 1 is equipped with reinforcement 4, described reinforcement 4 is strip structure, the opposite side surface of described geotextiles body 1 is evenly equipped with anti-skidding protruding 2, described anti-skidding protruding 2 for the rectangular structure with groove 3, and described groove 3 is frustum structure wide at the top and narrow at the bottom.
Reinforcement 4 is made up of high-density polyethylene material, and intensity is high; Lower end caves inward and is formed with triangular prism connected in star 5, makes reinforcement 4 also have good skidproof effect. Reinforcement 4 equates with anti-skidding protruding 2 height, and interlaced distribution, is convenient to stack transport.
The present invention is simple in structure, when making full use of synthetic staple fibers needling nonwoven geotextiles advantage, is provided with reinforcement 4 on one side surface, has increased tensile strength and the non-deformability of short fiber geotextiles all directions; What on its opposite side surface, be provided with is anti-skidding protruding 2, utilizes anti-skidding protruding 2 structure to hinder the relative sliding of short fiber geotextiles and its surrounding medium all directions.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
