UV CIPP: Pipeline Rehabilitation Project for Sewage Pump Station
The project involved the establishment of a new sewage pump station with a capacity of 45,000 tons per day, along with the upgrade of an existing facility to enhance its capacity to 55,000 tons per day.
Xiamen, October 20, 2023 — Recognizing the increasing significance of urban infrastructure, Anyue has successfully completed the rehabilitation of a sewage pump station in Xiamen. This project highlights Anyue’s expertise in trenchless pipeline repair and contributes to the ongoing efforts in maintaining essential urban facilities.
Project Background
The project involved the establishment of a new sewage pump station with a capacity of 45,000 tons per day, along with the upgrade of an existing facility to enhance its capacity to 55,000 tons per day. As urbanization progressed, the demand for effective wastewater management intensified, particularly in densely populated residential and commercial areas. The existing DN800 backup discharge pipe and main pipeline had suffered considerable degradation due to prolonged exposure to corrosive wastewater, necessitating prompt repairs. In addressing this challenge, the Anyue team employed UV CIPP (UV Cured-in-Place Pipe) technology to ensure the project was completed efficiently and sustainably.
Advantages of UV CIPP Technology
UV CIPP technology provided substantial benefits, particularly through its trenchless approach, which minimized disruptions to the surrounding environment and reduced construction timelines. This method utilized uv light to rapidly cure the liners within the existing pipeline, enhancing its corrosion resistance and structural integrity. The implementation of this technology not only improved the efficiency of wastewater treatment but also contributed to a safer living environment for nearby communities.
Rehabilitation Process
The rehabilitation process included the following key steps:
1. Pre-Cleaning Inspection: Conducted a comprehensive CCTV inspection to assess the pipeline’s condition.
2. Pipeline Cleaning: Employed high-pressure water jets to eliminate sediment from the interior of the pipe.
3. Material Preparation: Reviewed the rehabilitation materials and laid a base membrane to ensure the materials are protected from damage.
4. Material Unloading and Bundling: Safely unloaded materials and prepared them for installation.
5. Material Insertion: Utilized a pull rope to guide the materials into the pipeline.
6. Equipment Check: Verified that the uv curing lamps were functioning correctly.
7. Insertion of Light Chain and End Plug: Prepared for the curing process.
8. Pressurization and Curing Initiation: Initiated the curing process, ensuring the material tightly adheres to the original pipeline and fully is cured.
9. Curing Process Monitoring: Continuously monitored the curing effectiveness to maintain quality control.
10. Post-Repair Inspection and Acceptance: Conducted a final CCTV inspection to confirm the integrity and functionality of the rehabilitated pipeline.
Results
The successful execution of this rehabilitation project restored the pipeline’s functionality and significantly enhanced the efficiency of wastewater management. The Anyue team ensured that all aspects of the project adhered to established standards.
Anyue remains committed to advancing pipeline rehabilitation technology, focusing on innovation and professionalism to support sustainable urban development.
