Bubble run
Hey guys
It’s winter, or “vinter” as the boondockers around here say it.
One of the seasonal annoyances is “bubble run”, when the ground is frozen and the tripod legs melt down, and the instrument is out of level and refusing to work. It usually happens when you are on your longest shot, hence the longest walk back.
The problem stems from, what I’m able to understand, the pressure on the legs which melt the frozen ground much like an ice skate, as well as the metal leg caps heating up and conducting heat to those points.
The solution has always been to “bank” the legs with snow, which is an effective way to stop it.
The problem is, like around here now, when there’s no snow.
Yesterday I tried to “shadow” one leg with the total station box, and used a couple of rags for the other two, but that didn’t work.
Does anyone have a solution to this problem other than using snow?
Thanks.
