A method for mechanical cleaning of sewer pipeline in which before installation of two hoists over the first and the third pits one installs in those pits thrusts with blocks. The metal container is arranged as hollow semi-cylinder to both ends of which two traverses are connected to connection to cables, to one end of semi-cylinder link is connected, on that one valve is installed, this is arranged as semi-circle with possibility of turn by 90°. The metal container is drawn along canalization pipeline in direction of the first pit with valve forward by distance that provides filling of container, after that filled container is drawn back to the middle pit, emptying of container with removal of mud deposit is carried out in middle pit that is afterwards cleaned with removal of mud deposit. The operations of the metal container drawing in direction of the first pit are repeated till complete pipeline cleaning with removal of mud deposit, after that same operations are repeated in direction of the third pit. |
