Problems solved by technology

[0004] The purpose of the present invention is to provide a strip-shaped positioning clip based on plastic geogrid. By using the positioning snap ring, when the geogrid is gradually laid, the mesh on the geogrid is matched with the positioning snap ring, and then the The buckle plate is fixed, which solves the problems of the existing geogrid laying, because the geogrid is in a curled state, it is not easy to pave, it needs multiple people to fix the position at the same time, the installation efficiency is slow, and the time is long.

Abstract

The invention discloses a strip-type positioning latch based on plastic geogrids. The strip-type positioning latch comprises a positioning ring and a buckling plate, wherein pre-burying rods are annularly and uniformly distributed and fixed on one surface of the positioning ring; first stop blocks are annularly and uniformly distributed and fixed on the other surface of the positioning ring; the buckling plate is in sliding fit with the inner surface of the positioning ring; second stop blocks which are in clearance fit with two adjacent first stop blocks on the positioning ring are uniformly distributed on the periphery of the buckling plate. The positioning ring is designed, when the plastic geogrids are laid gradually, meshes in the plastic geogrids are matched with the positioning ring, the plastic geogrids are fixed by the buckling plate and then laid in the next step uniformly in the manner, the mounting process is simple, the structure is made of a plastic material and is simple in manufacture and low in cost, and laying of the geogrids is effectively guaranteed.

Description

technical field [0001] The invention belongs to the technical field of geogrids, in particular to a strip-shaped positioning latch based on plastic geogrids. Background technique [0002] The grid is a two-dimensional grid or a three-dimensional grid screen with a certain height made of polypropylene, polyvinyl chloride and other polymers through thermoplastic or molded. When used as a civil engineering, it is called geotechnical grille. This product is mainly used for side protection during underground mining of coal mines, and can be used as a support material for bolt roadways, support roadways, anchor shotcrete roadways and other roadways. When used for false roofs, it should be used in conjunction with two or more layers. [0003] When laying the geogrid, because the geogrid is in a curled state, it is not easy to pave it, and it needs multiple people to operate at the same time to fix the position, the installation efficiency is slow, and the time is long. Therefore,...
