Abstract
The proposed pipeline is made up of pipe sections connected in succession by elastic outer coupling elements having their entire surface brought into intimate contact with pipe section joints. Provided at the ends of the pipe sections are recesses for accommodating coupling elements therein. The method for laying the above pipeline involves successive joining of its pipe sections by means of continuously placing several layers of a binder-impregnated tape onto the joints. The pipeline is lowered into a trench before the binder sets. The machine for carrying out the method includes a carriage with a frame on which there is mounted a mechanism for connecting, pressure-sealing, and insulating pipe sections of the pipeline. This mechanism is arranged at an angle to the path of travel of the carriage and capable of reciprocating and rotating relative to the pipe sections being joined into a pipeline.
