Title: Method for trenchless replacement of underground service lines
Inventor: PORVATKIN N N
IPC: F16L1/024
Filed: 1996-10-09
Granted: 1999-02-27
Abstract: FIELD: construction engineering. SUBSTANCE: method can be used for trenchless replacement of existing underground pipelines including those made of steel in process of repair and reconstruction of underground engineering service lines. This also can be used in trenchless laying of housings made of steel pipes. According to method, laid is new pipeline which embraces existing pipeline. This is achieved by forcing into ground of pipe with open front end. Forced sinking of pipe with open front end is effected by applying impact load to rear end of this pipe. Then old pipeline is removed, new pipeline is cleaned of ground remained in it. Application of aforesaid method allows for easier removal of old pipeline due to fact that pipeline being sunken is preliminarily made with narrowed front end. Removal of ground is made easier because attached to internal surface of pipe being sunken is auxiliary pipe. In process of operation, periodically delivered through this auxiliary pipe is water under pressure so as to wash out ground penetrated into pipe in process of sinking. EFFECT: higher efficiency. 1 cl, 2 dwg

Algorithm compares modeled result with that obtained as result of measurements and evaluates comparison proceeding from remainder which is created by subtraction of corresponding signals. Diagnostic supervisor analyses remainder and determines whether motor runs without troubles or functions under some other mode. With detection of coming trouble diagnostic supervisor evaluates variables of motor generated as result of measurements, determines deviation from reference value and works out diagnostics of probable faulty or injured component.
