PUNE: The
Maharashtra State Road Development Corporation (MSRDC) has harnessed Italian
and Swiss techniques to control rock falls and landslides in the Bor ghat
section of the Pune-Mumbai expressway, especially during the monsoon.
MSRDC officials are employing techniques like high-tensile
strength wire-nets and rock-bolting at rockfall-prone areas. The MSRDC has
finished installing wire meshes at 85-90% of the critical areas in this
section.
Officials state preventive measures are being undertaken as
per guidelines provided by the IIT-Bombay. “A geo-morphological study and
survey was conducted at Khandala tunnel, Amrutanjan Bridge and Adoshi tunnel to
identify loose rocks. This was followed by loose scaling and removal of such
rocks,” an official said.
While travelling through the ghat section, one can see men and
machinery on engaged in installing meshes or rock-bolting. Shotcreting was done
on a patch between Khandala exit and Khandala tunnel. “This time we are
installing spider mesh, tecco mesh or quorex mesh, depending on the condition
of the rocks. Multiple meshes have been used at certain spots to increase the
holding capacity of the mesh,” said a supervisor working near Khandala tunnel.
MSRDC is also digging gutters where necessary. “We have taken
up de-silting and cleaning of drainage lines across the ghat section of the
expressway. Around 125 people are involved in pre-monsoon works, which cost
Rs52.19 crore,” an MSRDC official said. While one supervisor said the work
would be complete by June, the MSRDC did not commit to this, only stating that
it is in its final stages.
