1. Brief introduction of biaxial geogrid

Like Uniaxial geogrid, Biaxial geogrid are also made of the PP(Polypropylene) / HDPE( High Density Polyethylene )by the process of being stretched out, formed into lamella, punched regularly and then longitudinal and transverse elongated, which have much higher longitudinal and transverse tensile strength, especially in its prophase. These structures can provide soil a perfect and efficient standing and diffusing chain system chain moduli, which be used broadly to enable the permanent bearing capacity of roadbed.

2. Applications Biaxial geogrid can be used to enhancement of permanent bearable toft including roads and railways embankment, slope, tunnel, airfields, parks, docks and ground which cargo lays on their main usage are as follows:

1.                               Enhance the bearing capacity of road foundation and extend the duration of maintenance.

2.                               Prevent road surface from collapse, crack and being dirty.

3.                               Be convenient for construction, timesaving and cut down the cost of maintenance.

4.                               Prevent tunnel from crack occurring.

5.                               Further solidity slopes to proof water and soil from losses.

6.                               Reduce the surface thickness of the ground.

7.                               Consolidate the net for growing grass on the slope so as to stabilization surrounding evanescence.

8) Can be replaced by metal net for the coal mine off the top network. 3. Specification and performance parameter

4. Construction Notes:                                                                                                       

Excavation-bed, set up sand cushion (height of not more than 10cm), rolled into a platform for laying grille, the vertical axis should be the main force in the same direction, the vertical lap 15-20cm, horizontal 10cm, lap Service With plastic wrap and lay in the grille of every 1.5-2m with U-nail on the ground, laying the geogrid should be expected to fill back in time, the laying of the geogrid rise as the technical requirements.
