Improve Subgrade Stability with Column Point of Roughened
Geomembrane
Product Introduction
Uniaxial plastic geogrid is a kind of high strength of geosynthetic
materials. It is made of polymer by extrusion pressure into a
sheet,then rules mesh,and then formed by longitudinal tensile
treat. The process make the polymer being directional linear state,
and long oval mesh structure with homogeneous distribution, high
intensity nodes.This kind of structure has a very high tensile
strength and tensile modulus. To provide the ideal soil and
diffusion of chain system.The product with high tensile strength
(> 150 mpa),is a widely used reinforcement material adapt to a
variety of soil.
Product Properties
* Strengthening roadbed, can effectively spread of distribution
load, improve the stability and bearing capacity of subgrade,
prolong service life.
* Can bear larger alternating load;
* Prevent subgrade deformation and cracking caused by subgrade
material loss;
* Making the filled retaining wall improve filled soil bearing
capacity, reduce the soil pressure,save costs,prolong service life,
reduce maintenance costs;
* Slope maintenance with spray anchor concrete construction method,
not only can save 30% - 50% cost of the investment, but also can
shorten the cycle more than double;
* Adding geogrid in highway roadbed and road surface,can reduce the
deflection, track, delay cracking (3-9 times), 36% thickness of
structure layer.
* Suitable for all kinds of soil, no need different materials, save
work time;
* Simple construction,greatly reduce the construction cost.
Product Application
Widely used in dams,tunnels,ports,roads,railways,buidings,etc
constructions.
