Description

Introduction

Uniaxial plastic technical grid is a kind of technical material with high strength that uses high molecular polymer asmain rawmaterial, adds certain ultraviolet proof and aging resistance agent and makes messy chain shape molecules have drectionallayout and from linear status by unidirectional extension. Plastic technical grid makes directional tension undercertain temperature condition according to physical features of high molecule polymer,so its strength is very high in tension direction, tension resistance reaches 100-200Mpa,yield elongation rate is only 4-10%, it is near to the level of low carbon steel and much better than traditional or current reinforcement materials, and is very ideal synthetic material forstrengthening andreinforcement of civil projects.

Applications

Uniaxial plastic geogrid used to strengthen river and sea embankmentIt can be made into a gabion, and then used together with a grid to prevent the dam from being washed by sea water and cause collapse. The gabion is permeable, can slow down the impact of waves, prolong the life of the dam, save manpower and material resources, and shorten the construction period.
Unidirectional geogrid for cement pavement Geogrid is laid on the bottom of the cement pavement, which can reduce the rut depth, prolong the anti-fatigue life of the pavement, and reduce the thickness of the cement pavement to save costs.
