Drilling wells on clay soils often passes using a tin. At the same time, experts recommend using a heavy tool, and drag the lower part of the pipe. There were situations when, when performing these works, a light shock and scissors were attached to it. To accelerate the process carried out in viscous and strong clays, a couple of buckets of strong crushed stone should be filled up. By the way, if there is such a problem as storing things during the repair, then we advise you to follow the exiled link.
During cleaning the tin, water from buckets is added to the structure. For successfully done work in this basis, it is recommended to use a collapsible tool. In some cases, two elements with a similar diameter are used, while one works on the fence, and the second at this time is freed from rocks. In clay of medium density and loamy soils, an elongated tool is used, with which they work using a tool drum. The earrings bolt are unscrewed, and the earring itself is attached to the second element. This contributes to the rapid conduct of this process.
Worms of wells in sandy soils are carried out using a tin with flattened valves. At the same time, this tool cannot be allowed below the shoe. Approximately it should be at the level of pipes. For work on sand soil, the diameter of the tool should be less than the diameter of the pipes.
