METHOD FOR CLEANING PIPELINES AND RACES OF THE SEWERAGE NETWORK

摘要

1. A method of cleaning pipelines and risers of the sewer network, including the formation of a self-destructing piston and the implementation of its movement, characterized in that on a clogged section of the pipeline network into the inspection sewer well from the inlet of the water drains into the pipeline, a guide tube overpass with a total height of at least twice the depths of the well and its lower end of the compliant part of the overpass, for example in the form of a bellows, are inserted into the pipeline, and then into the outer edge of the undeformable smooth boat of the canal part of the overpass or riser, a pre-formed self-destructing piston of a diameter comparable to it is introduced with it and, due to gravity forces, provide it with accelerated movement in the overpass-pipeline system or riser and counter impact with blockage in the pipeline or riser until it is removed. 2. The method according to claim 1, characterized in that a self-destructing piston is formed by freezing aqueous solutions of known concentrations of detergents used to clean pipelines and risers. The method according to claim 1, characterized in that the self-destructing piston as a whole is formed in the form of a garland of separate component pistons with a central hole in them, placing the latter one after the other through their central holes on a flexible suspension, and along the length of the extracted suspension section when cleaning the pipeline judge the place of blockage in it. 4. The method according to claim 1, characterized in that the self-destructing piston is formed as a whole from individual disks of various compositions by freezing through a layer of water between them due to their internal cold content. The method according to claim 1, �
