Embodiment 1

[0047] Embodiment 1: A kind of three-dimensional plastic stretching net, comprises rib, rib and the square, rectangle, circle, ellipse, rhombus, right triangle or equilateral triangle grid hole formed by rib and rib intersecting, its It is characterized in that: on the intersection node of the rib 1 / rib 2 of the unidirectional, bidirectional, three-directional or four-directional three-dimensional plastic stretched net or on the rib 1 / rib 2, there is a fusion with the rib 1 / rib 2 An integral flange, the shape of the flange includes a hemispherical flange, a conical flange, a truncated conical flange, a polygonal pyramid flange, and a pyramidal truncated flange with a polygonal table top. The height of the flange is 3-110mm .

[0048] The flange includes a flange perpendicular to the rib 1 / rib 2, or a flange inclined to the rib 1 / rib 2, or a flange 5 with a curved arc, and the polygonal pyramid flange includes a triangular pyramid flange , a quadrangular pyramid flange and a 5-...

Embodiment 6

[0054] Embodiment 6 is attached Figure 6 Shown: a unidirectionally stretched double-faced rib is provided with a three-dimensional plastic stretch net with a rectangular pyramidal truncated flange on the table surface, and the rectangular pyramidal truncated flange on the mesa continuously penetrates both sides of the rib 2.

Embodiment 7

[0055] Embodiment 7 is attached Figure 7 Shown: The two-roll calender directly forms the initial strip with a single-sided flange, the lower roll is a smooth roll, and the surface of the upper roll is provided with concave holes for pressing the flange, and the plastic extruder is fed between the upper roll and the lower roll The melted plastic, the upper roller rotates clockwise, directly forms the initial strip with a single-sided flange.

Abstract

The invention relates to a three-dimensional plastic tensile net comprising bars, ribs and square, rectangular, circular, oval, rhombic, right-angled triangle-shaped or regular triangle-shaped grid holes formed by cross separation of the bars and the ribs, wherein flanges which are fused with the ribs / bars into a whole are arranged on cross nodes of the ribs / bars of the single-way, two-way, three-way or four-way three-dimensional tensile net or the ribs / bars, and the flanges can be hemispherical flanges, tapered flanges, circular truncated cone-shaped flanges, polygonal pyramid-shaped flanges or truncated pyramid-shaped flanges with polygonal table tops. The manufacturing method comprises the steps of preparing an initial material strip with the flanges, punching, heating, stretching longitudinally, stretching transversely and rolling a finished product. The three-dimensional plastic tensile net is used for road widening and reinforced retaining walls, can be laid at the bottom or side slopes of river courses and can improve withdrawal resistance, earth fixing ability, anti-scouring ability and collapse resistance; and compared with a traditional two-dimensional planar tensile net, the three-dimensional plastic tensile net can enhance the earth fixing effect and the vertical pressure resistance performance, improve the tensile strength at break and increase the drainage flux.

Description

technical field [0001] The invention relates to a geotechnical reinforcement material used in engineering fields such as embankment, road and railway embankment or slope treatment, in particular to a three-dimensional plastic stretched net and a manufacturing method thereof. Background technique [0002] Plastic geogrid is a geotechnical reinforcement material widely used in engineering fields such as embankment, road and railway embankment or slope treatment, and the effect is remarkable. The traditional one-way, two-way, three-way (such as patent No. CN03154700.1), four-way (such as patent No. CN201020061351.0) plastic geogrids are all made of smooth plastic sheet as the initial material, after punching, heating stretched, as attached figure 1 As shown, it is a two-dimensional planar network structure, and the effects of pullout resistance and soil consolidation still need to be improved in engineering practice.
