Arrangement of any well is not limited to drilling of the well, creation of trunk of well and the clay lock. Creation of head of well – upper part in which convenient approach to well has to be provided is of great importance. Usually the well is made out lodge (central, Ural and Siberian regions of Russia) and crane (southern areas).
Instruction
1. The mechanism of crane consists of the basis – the thick log having fork on the top termination or opening and thinner log or pole balance weight. Among themselves they are connected by means of metal rod. The rod is driven in into the balance weight at such level that one end of log balance weight always outweighed. For this purpose attach additional cargo to it. On the thin and easy end the long pole, rope or rope with bucket is attached.
2. For the basis pull out near well hole the more deeply the better. Do not dig too close, otherwise it is possible to damage the clay lock which you did for protection of well against hit in it melt and rain waters. Insert log into hole and fill in with concrete. To one here of course not to cope. That the balance weight did not loosen log basis tie the heavy end to support. Until concrete grabs, do not remove log balance weight from support.
3. As we see, the crane device very simple, strong and economic, but it has also minuses. Most important is that the well is not protected from hit in it of dust and dirt. It can be overcome, having established cover on the mine. However practice shows that the cover in such wells is seldom closed because very inconveniently constantly to close and open it.
