biaxial geogrid materials:PP roll size:4m*50m tensile strength:30-150KN/M PP biaxial geogrid

PPbiaxial geogrids

 materials:PP roll size:4m*50m tensile strength:30-150KN/MPP biaxial geogrid

It has much higher longitudinal and transverse tensile strength.The structure can supply alinking system to soil.

                                           

      Biaxial geogrids are made of macromolecule polymer by the process of being stretched out, formed into lamella, punched regularly and then longitudinal and transverse elongated. They have much higher longitudinal and transversetensile strength. These structures can supply alinking system to soil, which be used broadly to enable the permanent bearing capacity of roadbed.

      Usage: 1)Suitable for strengthening road and railway base. Improve loading of road and railway base.

2) extending usage validity. Prevent surface of road and railway from breaking.

3) Reducing maintaining charges. Shorten construction time.

4) Increase loading capacity of base. Prevent land soil from sinking; including embankment, slopes, tunnel, airfields, parks, docks and so on.

5) Tighten slopes to proof water and soil from losses.

6) Reduce the surface thickness of the ground.

7) Prevent tunnel from crack occurring.

8) Save construction time and cut down the cost of maintenance.

 

 

The spreading surface should be even. After it is checked and accepted, in order to avoid the vertical deflection, line out the while line or the seton in the spreading surface according to the width, spread it, and then fix the end of the geo-grid by the iron nail (8 nails per meter in width).

After fixing the end of the geo-grid, use the spreading machine drawing and spreading forward, strain and make it straight by manpower when spreading per 10m till spreading a reel of geo-grid. The following operation is the same when spreading others.

After spreading a reel, use the 6T-10T road roller grinding the total road. (If it is spread on the middle plane, it is best to use steel-roller road roller; if it is spread on the concrete road, it is best to use the glue-roller road roller).

Constant spreading: Take the length of the reel as the spreading section, after spreading, inspect the spreading quality completely, and then spread the following section. Keep 10-15cm between two grids, fix it by the iron nail or the chock, continue to spread the second section.
