    The Snow and Avalanche Study Establishment (SASE), a DRDO laboratory based here, has developed a cost-effective model for repairing the fence along the Line of Control in Jammu and Kashmir which gets damaged due to excessive snow loads and cold weather every year.

    The new design, also referred as the Anti-Infiltration Obstacle System, consists of hollow section steel posts of pre-determined specifications and concreting with a special grout mix-up to the required depth. A double-twisted galvanized mesh has been added to either side of the concertina wire coils to cater to the snow load and even the method of fixing the concertina coils to the posts has been modified.

    Field trials for the new design were conducted in certain specific sectors along the LoC during winter and the impact of snow and weather on the structure was analysed after snow melt. The SASE and the Army are working out on optimisation of certain parameters and design specifications, sources said.

    The design has met the requirement for installation on the ground and along the vertical slope, that is, from top of a hill to the bottom. The next stage is to develop a structure suitable for fixing horizontally across the slope, that is, from left to right. The snow load on the fence which lies across the slope is heavier than the weight it has to bear when placed along the slope.

    Most of the frontier with Pakistan, including the international border and the 743-km LoC is fenced to check infiltration. Several hundred kilometers of the fence runs through areas that remain heavily snowbound in winters. The damage to the fence was largely due to its rudimentary design and poor foundations of the posts. This resulted in deployment of large manpower for yearly maintenance and repairs, leading to high recurring costs.
