UV curing repair of pipelines in Ganzhou City

Non excavation repair of municipal pipelines using CIPP ultraviolet curing inner lining curing repair method

Characteristics and advantages of UV curing repair:

Non excavation CIPP ultraviolet curing repair of pipeline defects in Ganzhou City. Starting from this year, Ganzhou City has implemented the urban center water project, achieving a further improvement of urban water bodies from "good water" to "clear water" and "beautiful water". As of now, the sewage pipe network construction and repair projects included in this year's practical projects have exceeded the annual targets.

The clear water project in the urban center of Ganzhou City mainly includes four projects: source control and sewage interception, expansion of active water surface, dredging and connection, ecological water purification, and long-term management. At present, the construction and repair of the sewage pipeline network in the source control and sewage interception project have completed a total of 285.48 kilometers, exceeding the planned task by 9.6%, of which 224.6 kilometers have been completed this year.

The deputy head of the Supervision Department of the Ganzhou City Water Supply and Drainage Management Office said that 179 kilometers of sewage pipelines have been laid in urban and suburban villages to achieve full coverage of the sewage network. At the same time, we have also carried out interception at 1743 sewage discharge points along the river.

Recently, reporters saw at the construction site that construction workers were inspecting the road network of Changxiangdong Avenue, pumping water from the network and using robots to carefully inspect it.

“CIPP UV cured inner lining curing repairOur team consists of 16 people, and the daily workload for dredging and inspection is about 300 meters. The robot mainly goes down the well to inspect the internal situation of the pipeline, providing effective basis for the next step of repair. ”Mr. Zhang, a construction worker on site, introduced that there are currently 15 teams working on Changxiangdong Avenue, with 8 teams conducting pipeline inspections and 6 teams conducting pipeline repairs.

Then put the ultraviolet lamp group into the pipe network and utilize the curing property of resin when exposed to ultraviolet light,

Ganzhou City pipeline UV curing repair controls the UV lamp to move at a certain speed within the pipeline network, gradually curing it to form an inner lining tube with a certain strength, thereby repairing the pipeline.

XCMG said that curing a 50-60 meter section of pipeline with a UV lamp for one and a half hours is sufficient. "After curing and repairing, the pipeline has the advantages of corrosion resistance and wear resistance, which can prevent groundwater infiltration. It can also improve the structural strength of the pipeline, and the general service life can reach 25 years

It is reported that the total length of the rainwater and sewage pipe network testing and repair project in Ganzhou City is about 190 kilometers, with a total budget investment of 55 million yuan. Mainly targeting the comprehensive renovation of rainwater and sewage pipelines in the main urban area, high-tech industrial park, Guyang Industrial Park, Jingshi Road, and internal sub roads of the university park. The project adopts two technologies: excavation and non excavation repair of the pipeline network. The use function of the rainwater and sewage pipeline network collects basic information of the urban rainwater and sewage pipeline network, providing a basis for the construction of a digital platform for the rainwater and sewage pipeline network. In addition, the project will also carry out rainwater and sewage pipe network diversion renovation for 34 old residential areas.
