Reinforced pressure-resistant geogrid

Abstract

The invention discloses a reinforced pressure-resistant geogrid. The reinforced pressure-resistant geogrid is used for solving the problems that an existing geogrid is poor in pressure resistance, prone to breakage and free of water retention performance, water retention is not carried out on the road surface, and the use effect is influenced. The reinforced pressure-resistant geogrid comprises ageogrid body, the geogrid body is composed of a plurality of longitudinal grid bars and transverse grid bars, nodes are arranged at the joints between the longitudinal grid bars and the transverse grid bars, the outer surface of the geogrid body is adhered with a water absorption film through a bonding agent, a plurality of protruding points are integrally formed on the upper surface of the waterabsorption film, a woven net is arranged inside the geogrid body, the woven net is formed by weaving a plurality of reinforcing ribs, the reinforcing ribs comprise inner cores, a plurality of steel rings are uniformly arranged on each inner core in a sleeving mode, polyphenylene sulfide sleeves are wrapped on the outer surfaces of the inner cores and the outer surfaces of the steel rings, and eachinner core is formed by twisting a plurality of thin steel wire ropes. The geogrid has good tensile property, pressure resistance and water retention performance.

Description

technical field [0001] The invention relates to the technical field of geogrids, in particular to a reinforced pressure-resistant geogrid. Background technique [0002] Geogrid is a major geosynthetic material, which has unique performance and efficacy compared with other geosynthetics. It is often used as reinforcement for reinforced soil structures or reinforcement for composite materials. Geogrids are divided into four categories: plastic geogrids, steel-plastic geogrids, glass fiber geogrids and polyester warp-knitted polyester geogrids. 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. The existing anti-compressive performance is poor and easy to break, and has no water retention performance, and does not retain water on the road surface, which affects the use effect...
