Lol "Houston... we have a problem". The 4" of rain we had this week done her in. l started digging the tunnel in 1983 collapsed about 7 feet long out of the 15' running length. I noticed a couple years ago that the water coming of the nieghbors round top had started to run under my deckagon grainery, last year i could see under it was going down the 15' deep main shaft. Put it on my mental things to do list. I relaced all the timbers in '98, the hard clay down there was still perfect. Haven't looked down there since 2007?
Saturday morning i had a hole about 3' outside the grainery. I called Tom and he happened to have about 7 yrds of dirt on his '58 Viking so he dumped that out lastnight. Came over about noon with his Case "Construction King" backhoe/loader. Not near enough dirt to do the job. I started throwing tire/wheel combos down the main shaft while he made a quick sand damn in the creek bed and started moving sand up. Put 8+ yards in, pushed down worked around and got all except the last 3' out of 15'. It was hard as a rock on the northend where the water hadn't got. Pushed a bit of sand into it, tamped everything down with the backhoe then the dirt and packed it. 15 yards of fill, problem solved
