    Product description

    Uniaxial Tensile Plastic Geogrid is a kind of high molecular polymer as the main raw material, adding certain anti-ultraviolet and anti-aging additives, after unidirectional stretching, the original scattered chain molecules are reoriented and arranged in a linear state high-strength geotechnical materials. Much better than traditional or existing reinforced materials, it is an ideal composite material for civil engineering reinforcement and reinforced reinforcement. According to different raw materials, it can be divided into unidirectional stretched polypropylene geogrid and unidirectional stretched high-density polypropylene Vinyl geogrid.

    Uniaxially stretched polypropylene geogrid is made of polypropylene (PP), which is plasticized and extruded, punched, heated and stretched. The stretched geogrid has quite high tensile strength and elastic modulus, and the uniaxially stretched polypropylene geogrid is suitable for the construction of roads, railways, ports, and reinforced retaining walls along rivers, lakes and coasts. For dams, bridge decks, steep slopes and other projects, this kind of unidirectional geogrid can greatly improve the bearing capacity of the project, prolong the service life, reduce the occupied area, facilitate construction, shorten the construction period, reduce the cost and reduce the maintenance cost.

    Uniaxially stretched high-density polyethylene geogrid is made of polyethylene (PE), which is plasticized and extruded, punched, heated and stretched. The creep resistance of uniaxially stretched high-density polyethylene (HDPE) geogrid is 2-3 times that of uniaxially stretched polypropylene (PP) geogrid, so uniaxially stretched high-density polyethylene (HDPE) The creep resistance of geogrid is better, and this kind of unidirectional geogrid is generally used in the construction of "100-year project". These two geogrids are referred to as unidirectional geogrids for short, and belong to plastic geogrids.

     

    Features of Uniaxial Tensile Plastic Geogrid:

    1. High unidirectional tensile strength, good creep resistance and stable chemical properties;

    2. The coefficient of friction with sand and gravel is large.

     

    Application range of Uniaxial Tensile Plastic Geogrid;

    1. Mainly used for retaining walls, abutments, steep slope projects, etc.;

    2. Retaining walls and bridge abutments are stressed structures that bear all external loads: active earth pressure, dynamic loads on the upper part of the structure, temperature stress, etc. The reinforced material is under long-term tension, and the dynamic load Under repeated action, the molecular structure of the material will be fatigued, its performance will be attenuated, and the aging of the grid will be accelerated. In order to avoid large deformation of the structure due to the creep of the reinforced material, a unidirectional geogrid made of high-density polyethylene (HDPE) should be selected.
