Screw piles are a type of piles that is buried in the ground using a method of combining screwing and denting. Screw piles consist of the shaft and the blade (or blades). They are made of molten or welded steel pieces. Screw piles are used widely in the construction of different kinds of buildings and facilities, which is attributable to high installation speed, reduced vibrations when dented and ability to conduct installation works in winter seasons.

Drilling boreholes for cathode protection
Deals with corrosion of gas pipelines from stray currents and soil corrosion.
Drilling boreholes for cathode protection is a measure of active protection of pipelines, dealing with problems like:
Suppression of stray currents on the pipeline;
Stray current drain
Cathode protection is one of the ways of protecting underground facilities and communications from current-induced corrosion. Usually this measure is used to protect pipelines and trunk cable lines. For cathode protection to function properly, it is required to install anodes, which will conduct electrical currents into the ground. Anodes are installed into the boreholes drilled specifically for this purpose. When there is a big number of boreholes to be made, mobile drilling rigs are being utilized.
