Embodiment Construction

[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0025] The polyester fiber node injection-molded geogrid of the present invention includes a transverse strip and a longitudinal strip, and the transverse strip and the longitudinal strip are all composed of a polyester fiber inner core and a polypropylene or polypropylene coated outside. The coating is composed of vinyl, the polyester fiber core of the inner layer is the main stress layer, which improves the strength of the strip, and the outer layer of polypropylene or polyethylene is the protective layer, which protects the stress layer from damage, and the double-layer structure design , while effectively improving the strength of the strips, it significantly prolongs its service ...

Abstract

The invention discloses a polyester fiber joint injection molding type geogrid and a processing method thereof. The polyester fiber joint injection molding type geogrid comprises transverse strips andlongitudinal strips; each of the transverse strips and the longitudinal strips consists of a polyester fiber core arranged inside and a polypropylene or polyethylene coating arranged outside; the transverse strips and the longitudinal strips intersect to form a grid shape; joints are formed at the intersecting positions of the transverse strips and the longitudinal strips; a reinforced block which is integrally injection-molded and is made of a polyethylene material is arranged at each joint, the joint is positioned in the center of the reinforced block, and the reinforced block is of a square structure with a slope at each edge. The geogrid has the advantages that the tensile strength is high, the joints are not liable to peeling-off and corrosion, the interlocking with a soil body is strong, and the cost is saved.

Description

technical field [0001] The invention relates to the technical field of geogrids, in particular to a polyester fiber node injection-molded geogrid and a processing method thereof. Background technique [0002] Geogrids are widely used in the construction of roadbeds, dams, slope protection and other projects. They can protect roadbeds, slope protection and prevent soil erosion. The existing integrated geogrids have poor tensile capacity and the node positions are easy to peel off. A polyester fiber node injection-molded geogrid with high strength and its processing method that can solve this problem still needs further research and development. Contents of the invention [0003] The object of the present invention is to provide a polyester fiber node injection-molded geogrid and its processing method in view of the technical defects in the prior art. [0004] The technical scheme adopted for realizing the purpose of the present invention is: [0005] The polyester fiber n...
