Speedy excavation of trestle tower base in remote areas

Excavation by drilling and blasting is the conventional method of casting foundation on rocky soil. But these technologies have their drawbacks e.g. getting statuary permission for blasting, potential for damages to nearby slopes, structures and area due to vibration. Transportation of excavator to an area at higher elevations, in thick vegetation covered with trees and bushes, not connected by proper roads poses many practical problems of remote area access. This paper attempts to present techniques and methods to overcome these problems. This need-based, objective specific professional interest paper reveals that in remote areas where trestle towers of high tension power lines are erected, speedy construction is possible despite lack of infrastructure. Without much destruction of the jungle and negative impact on wildlife, considerable project cost and time could be saved. Bottlenecks of statuary permission problems are possible to remove thereby bringing ease for the project executing company. Without many extra inputs, impetus can be given to such ongoing and planned construction works. The ensuing technical communication also concludes that knowledge of excavation and mining is useful and applicable in the power sector too, though both areas are sharply different from one another.
