System and method for partially repairing drainage pipes

Abstract

The invention provides a local repair system and method for a drainage pipeline. a system on the ground comprises a control system, a driving system, a draught fan and a generator set providing a power source for the system on the ground and a downhole system; the downhole system includes a CCTV pipeline inspection robot and a light-curing repairing device; the driving system drives the light-curing repairing device to move inside the pipeline and detect and diagnose the inner part of the pipeline; after breakage points are detected inside the pipeline, a signal is sent to the control system;and after the driving system drives the light-curing repairing device to move to the breakage points, the draught fan conveys the air volume to the light-curing repairing device, and the light-curingrepairing device starts ultraviolet lamps to repair the breakage points inside the pipeline in sequence. In the construction process, a trenchless mode is adopted, the automation degree is high, the strength is low, and the efficiency is high; construction on the ground occupies small space, and the safety is high; no noise and no disturbance to residents exist; the curing efficiency is high; thecuring process is controllable, and can be monitored in real time; the repairing is accurate; and the repairing operation with water is realized through the combination of normal temperature points and ultraviolet ray curing repairing.

Description

technical field [0001] The invention relates to the field of repairing drainage pipes by ultraviolet light curing, in particular to a partial repairing system and method for drainage pipes. Background technique [0002] At present, pipeline ultraviolet repair technology has a history of more than 100 years in many sewage pipelines and tap water pipelines in western developed countries. At present, there are about 5 companies conducting research on pipeline repair technology and equipment in the world, most of which are located in Germany, among which PROKASRO Machinery Co., Ltd. has a relatively high market share. The restoration equipment it produces accounts for about 70% of the global market. Most of the domestic restoration equipment is imported. [0003] Ultraviolet in-situ curing repair technology is an advanced technology in the world. The emergence of ultraviolet in-situ curing and repair technology has greatly reduced the social cost of the entire drainage pipelin...
