Описание: A nice little job for Monday morning. Joe Ward does a lot of road improvements and maintenance for DELWP (Public land managers) and I often give him a hand when rock is encountered. The existing culvert was not functioning well as a lot of water was going under the pipe and not through it. The exit end of the pipe had a massive rock on top of it that had to be reduced in size so it could be removed. The large rock was drilled with 3 holes each 35mm x 600mm deep, each hole was loaded with 1/3 of a plug of 32mm packaged emulsion and fired with det cord. This light load was just enough to break the rock into large pieces that could be used as building material when the culvert is rebuilt.
