Lining pipe attaching device and method for CIPP elbow repair

Abstract

The invention discloses a lining pipe attaching device and method for CIPP elbow repair. The lining pipe attaching device comprises sphere mechanisms capable of expanding. The multiple sphere mechanisms communicate through a pipeline mechanism. An attaching mechanism is arranged on the pipeline mechanism in a sliding manner. A traction assembly is arranged in each sphere mechanism. The traction assemblies in two adjacent sphere mechanisms are connected with the attaching mechanism through traction ropes, and thus the traction assemblies can drive the attaching mechanism to move in a reciprocating manner in the length direction of the pipeline mechanism through the traction ropes. The attaching mechanism comprises sliding rings sleeving the pipeline mechanism, a supporting disc, a first crank, a second crank and a rolling sphere. One end of the first crank is hinged to the supporting disc, and the rolling sphere is arranged at the other end of the first crank in a rotating manner. One end of the second crank is hinged to the siding rings, and the other end is hinged to the first crank. The device and the method solve the problem that after a traditional CIPP technology is utilized for repairing an elbow, a lining pipe cannot be effectively attached to the inner wall of a pipeline.

Description

technical field [0001] The invention relates to the field of repairing CIPP pipelines, in particular to a liner fitting device and method for repairing CIPP elbows. Background technique [0002] CIPP in-situ curing method is an underground pipeline repair process in the non-excavation industry. CIPP technology is widely used and is suitable for non-excavation repair of gravity flow pipelines, water supply, gas and other pressure pipelines; its principle is: the outer layer is coated with poly The lining pipe of ester resin or epoxy resin is turned over into the sewer or sewage pipe by water gravity or compressed air pressure, and then heated with water, or steam, or ultraviolet UV heating, so that the resin undergoes a chemical reaction and solidifies. After the lining pipe is cured , will form a new continuous lined pipeline with full structural strength in the original pipeline, and can repair the damage of the underground pipeline without excavating the road. In the exis...
