Geo-synthetic product based systems(Geo-systems) are used for various applications in civil,environmental and other engineering applications.For instance
the thickness of the aggregate layer in a typical cross section for road construction can be reduced by using these systems (by also keeping in view of the provisions in the code, so that less of quarrying is required).
river training works and sea wall construction the use of sand /rocks /stones /aggregates for creating protection structures or barriers could be eliminated to some extent by making use of dredged and reclaimed materials/ locally available slurry or any such
by encasing them in the suitable Geo-systems or in tube form(Geo-tubes)
Geo-systems should ideally facilitate sustainable #construction by reducing the use of natural materials like aggregates, sands and rocks etc apart
from facilitating other functional supports such as filtration, separation and reinforcement qualities.Let us get into the details and see how far these systems are helpful?
(Note:Please do not forget that, apart from facilitating sustainable
construction, Geo-systems serve the precious purpose of protecting life and property from the vagaries of nature by being part of the control systems outlined below)
Flood control: Geo-systems for flood control
Flood control bags, Geo-tubes and other stand alone systems or combination mechanisms.(Huge woven Geo-bags for example)
the specific condition prevailing this need to be designed taking note of the historical data available for flood occurrences previously such as HFL and other engineering considerations.
Erosion Control: Erosion control mechanism with Geo-synthetics
Systems made of Geo-textiles(Woven or non Woven)| Gabions|Grids and other products again independently or combined together as per the specific purpose for which this needs to be designed.
For example river banks, steep slopes on cuttings and beach
side would require different considerations while selecting the system. Geo-tubes would be suitable for beach nourishment and prevention of erosion on the marine front. However the gabions may be more suitable if the height is more because this could be constructed
as a wall by itself to protect the side slopes.
Embankment construction on soft soil: PVD's/Geo-grids and other Geo-systems.
It could be formation for a road or a railway line and in such a cases geo-grids and high strength woven geo-textiles or other products needs to be used again as per a specific design.
In cases where
the soil bearing capacity is negligible there is also a need to do ground improvement in the first place.
If it is a dredged and reclaimed area then it calls for using the vertical drains(Pvd's) to facilitate the process of consolidation relatively
easy to start constructing on a faster basis.
Sub-grade strengthening :Geo products can be made use of in strengthening applications very effectively.
In all such applications depending on the particular site specific data the geotechnical engineer and the consultant in charge of the project need to take a call on the appropriate geo-synthetic system that
would bring in the desirable results.
Often Geotextiles, Geogrids and even Geo-cells would be ideally suitable for these type of applications.
River training works and Sea wall construction:
some of the systems used in this case.
There are soft solutions and hard solutions in these cases again. While mostly in river training Geobags or even Gabions could be made use(of course there are other new systems being developed).
it comes to sea walls the concept is different.Obviously we are tackling a big wave force in these cases and also we need solutions which will sustain even the effect of Tsunami waves if such a situation were to occur.
So seawalls are ideally made in
combinations with large sized rocks/quarry stones which is used also along with appropriate Geo-systems .
In fact the applications of Geo-synthetics in civil engineering being a vast topic only an attempt to touch the very basic aspect is made here.Thanks
