SUBSTANCE: method comprises setting the pipe into the outer shell, setting plugs in the faces of the shell, and supplying cement-sand mixture into the space between the pipe and shell. The bearing centering rings are mounted in advance throughout the pipe length. The rings are covered with a polyethylene shell, excluding the pipe ends, the pipe is inclined, and cement-sand mixture is supplied under pressure through the opening in the plug from the bottom face until the mortar appears in the opening of the plug at the opposite face. After the solidification of the mixture, the plugs are removed.
