What is the difference between one-way and two-way geogrid geogrid?

What is the difference between one-way and two-way geogrid geogrid?

Uniaxial geogrid and Biaxial geogrid belong to geogrid, on the side of the roads, ports, airports, mines and other very widely used in subgrade engineering construction, that between what's the difference? 

The following content is easy for everybody to introduce:

1, product appearance

Bidirectional geogrid is two-way rashin, porous structure, square mesh grille.

Unidirectional geogrid is a bearing and drawing, a square mesh is thin.

2, the processing technology

Unidirectional geogrid rashin are fit together on extrusion processing of polymers of open hole, then heating network of shaped structure of raw materials, according to different raw materials can be divided into one-way polypropylene geogrid, 20 kn two-way geogrid, a one-way: high-pressure polyethylene geogrids in azimuth rashin are the characteristics of this kind of raw materials with very high tensile strength and strain rate rashin. It gives layers presented the idealized franchise chain system software, and rashin rate is low. It is at present relatively ideal reinforcement corrosion material.

Is in a one-way two-way rashin gratings rashin again and become basically do have a square hole mesh structure of raw materials, see more polypropylene raw materials, the raw materials in the vertical and horizontal with has great tensile strength and strain rate. This kind of structure in the soil layer showed a more sound franchise chain system software, thus applied in large-scale capital increase permanently installed.

3, in the construction

(A). Place the bidirectional geogrid and soil, the surface or among the layers of material, using the interaction between soil and geogrid, can use sand good compressive capacity and compressive strength properties of plastics, make all sand overall tolerance standard be improved. For one-way geogrid improved the steep slope of the secondary, further improve the steep slope, prevent soil erosion

(B). retaining wall and dark building structural slab culvert belongs to, and take the full load: active earth pressure, load, temperature stress, etc., at the top of the building structure reinforcement materials under the long-term effect is in a lot of support, and under the effect of loads, the formula of raw materials cause fatigue, its features produce attenuation coefficient, accelerate the embrittlement of grille. To prevent structure because of the raw material of the stiffener stress relaxation caused by large deformation, should be selected with high density high pressure polyethylene (HDPE) as the raw material of unidirectional geogrid.
