Seeking advice for farm fence post erection on rock surface

[Ashwin]

I am setting up electric fencing on the farm perimeter using stone fence posts of 5.5-ft height. The stone quarry is nearby so I get a good price including transportation. The posts are erected by digging using an earth augur with a bit size of 9 inches to a depth of just above 1 feet.

I have a section of the premiere (approx 1200 running feet or 150-175 pillars approx) which is hard rock. The area is non-cultivable but I hold the rights to the area and intend to fence it in along with rest of the farm. No augur machine would work on rock surfaces and general tractor-mounted drill but sizes are .75 inches. The rock drill bit is too thin for a GI pipe of 1.5 inches. On the other hand, erecting the same stone poles with concrete is a setting/centring problem initially until the concrete sets and cured.

Have you seen any ideas or examples or have yourself solved this problem in a cost-effective way? My landed cost of a stone pillar is 225 per piece of 5.5ft, and the additional charge of shifting and fitting is approx 75-100 rs per pillar into medium hard laterite/limestone mix soil

Please share your ideas on how to set up fence post on rock?

ThnQ for Providing an Opportunity in Advising for your Farm Fencing. Because your land is Rocky are you can put PILE FOUNDATION by putting MS Rods of 12 MM of 1 Foot to lay the Rock Poles / Iron Poles / Cement P{oles. I am sincerely advising you to go for Barbed Wire Fencing Instead of Solar Fencing (Costlier), because yours only to safe Guard your Land. .

Finally got the rock surface drilled using 1.5 inch drill bit that comes with a tractor mounted air compressor. Put in 1.5inch GI pipe with some cement to hold it firmly in place.

GI Pipes come in 20ft units costing roughly 690Rs, so per pole cost is around 230Rs and 80 per 1feet hole and cement+labour.
