FIELD: construction, pipeline.
SUBSTANCE: invention pertains to construction and repair of lineal part of transit pipelines, mostly underwater. Caisson for repair of underwater pipelines contains a case - shaped chamber with open bottom and one of the lateral walls, in two other opposite side walls whereof there are segmental grooves arch radius whereof corresponds to the radius of the repaired pipeline providing a possibility of adhesion of the chamber to the outer surface of the pipeline along the forming lines and circular arcs forming a diving - bell, a fixture holding the chamber of the pipeline and a fixture holding the chamber against the ground connected with the chamber turning around the axis of the pipeline.
