Pachhi-Pakke road section
Removal of loose hanging materials from the crown part, and accumulated debris from the toe portions. Construction of lined hillside drainage. If possible wire mesh net can be installed. Also retaining wall of suitable height can be constructed.
High degree of weathering of rocks coupled with daylighting of adverse orientation of geological discontinuities due to steep slope cut. Also the percolating rainwater have further degraded the stability of the slope face.
