Abstract

When drilling in soil and simultaneous loading of casing tube it is desirable to be able to use casing tubes of plastic material such as PEH-plastic. This is made possible by a special design of a casing shoe (5) giving a strong joint between the casing shoe (5) and the casing tube (4). The casing shoe is made of metal and has a part (62) which is perforated of holes (63) filled with the plastic material. Tube couplings (12A, 12B) between the casing tubes can also be joined to the tubes (4A, 4B) in the same way as the casing shoe, i.e. that they are made of metal and each has one part (12A, 12B) perforated of holes (63A, 63B) filled with the plastic material.
