geogrid ,single-direction geogrid,biaxial geogrid Biaxial geogrid ,single-direction geogrid

Propertiesgeogrid is made by pressing and pulling in double-direction the PP(Polypropylene) / HDPE( High Density Polyethylene) especially. The geogrid can decrease the quantiy of the filling, envenly distribue the load stress and has high module in double-direction pulling and tensile strength and high destroying resistance and endurance. It has the property of homogenous structure, low creepage, anti-aging, acid and alkali.and so on.UsageMostly used in soft base disposal and reinforcement of the soil structure and all kinds of reinforcement of soil base. It can divide the load stress, increase uneven settlement. And used in the work of highway, railway, harbor, airport, municipal construction. Packing size detailWidth≤4.0m, length: 50m

1. Brief introduction

Like Uniaxial geogrid, Biaxial geogrid are also made of macromolecule polymer 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 geogrids 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.
