FIELD: construction.
SUBSTANCE: segment is formed as a unified whole from at least a plate of inner surface which forms inner surface in a circumferential direction of recovering pipe, and side plates with a mounting hole, the plates are located on both sides of inner surface plate so that to pass in a circumferential direction of recovering pipe. Coupling tool includes tubular joint pin designed with possibility of pin dividing in halves and introduction of the first segment into the mounting hole in side plate with a part of joint pin which is outside the first segment. In addition coupling tool contains dividing pin which may be introduced into tubular joint pin in order to divide joint pin in halves and to press them to the first segment for attachment to it. The pin halves which are outside the first segment, are introduced with latching in the second segment through the mounting hole of its side plate thus coupling the first and the second segments in longitudinal direction of recovering pipe.
EFFECT: improving the method.
