problem
Weathered stones, climatic changes, water infiltration, erosion,
cycles of frost and thaw can result in rock particles and stones
falling onto existing roads and civil engineering structures.
solution
When a rock face slope is adjacent to a road, the hazard
of falling rocks may be controlled by cladding the face with a bi-axial
geogrids of the type TENAX RS 320. Lengths of geogrid are fixed
at the top and along the slope with anchors (steel rebars) and a
network of steel ropes, the dimensions of which are determined by
the type of rock strata.
Adjacent lengths of TENAX RS 320 SAMP geogrid are overlapped and
tied together at pre-determined intervals by using HDPE braid. In
respect to other systems, the use of geogrid integrates with the
environment and does not obstruct permeability.
TENAX RS 320 geogrids are manufactured from a unique process of
extrusion and biaxial orientation to enhance their tensile properties
and they are stabilized to withstand long term U.V. exposure, to
be able to guarantee a long term efficient protection.
TENAX RS 320, bi-oriented geogrids, are particularly useful to prevent
rock and debris from falling on roads and railways, due to their
high tensile strength and modulus, excellent resistance to construction
damages and environmental exposure to meet the strict requirements
for this type of work.
Furthermore, the geometry of TENAX RS 320 geogrids allows strong
mechanical interlock and a perfect adherence to whatever kind of
rock slope to be reinforced and contained.
conclusions
The use of TENAX bi-axial geogrids has resulted in a successful
solution for rock fall protection thanks to its integral structure,
flexural rigidity and tensile strength.
Geogrids helped to contain the rock face thus preventing rocks falling
from steep cliffs and cut slopes, and the scheme was completed efficiently
and economically.
Because of its strength and flexibility, TENAX RS 320 geogrids are
suitable to whatever kind of rock, on which it forms a continuous
protection against the falling of stones. |
