INTRODUCTION
Trench less technology is basically making a tunnel below the surface and installing services lines like water or gas pipes, electric or telecommunication cables etc with out any disruption to the public. It also makes it possible to install the utilities under rivers, canals and other obstacles with no disruption of flow and with minimum or no damage to the environment
Need for trench less technology
The disadvantages and difficulties encountered in conventional trenching methods have resulted in thinking of the need for trenchless technology.
The advantages of the no-dig technology are also responsible for the need of this technology to be adopted in mainly urban areas
Disadvantage of Open trench method
As the open trench is going to create obstruction roads, busy areas, diversions have to be provided before start of any digging work.
As the obstruction is created, the traffic has to be rerouted causing traffic jams.
Many a time, while cutting deep trenches in congested areas appear in the adjacent buildings.
Another difficulty, which is encountered very often is the damage caused to other service lines or cables present underground.
While cutting open trenches, trees, shrubs, gardens etc. may have to be destroyed damaging the environment.
Advantages
It reduces damage of valuable surface
It reduces the danger of improperly compacted excavations
It saves resources
It is accident free
It avoids traffic jam
It saves underground space
It reduces the impact on the enviornment
It provides a hassle-free road surface
Conclusion
By adopting this technology we can successfully implement pipes under the surface with out making any disruptions to the environment and public.
This enables us to retain our available resources. There by keeping the earth unexcavated
