PROJECT OVERVIEW
Provide full-process dredging, testing, and trenchless repair services for municipal rain and sewage pipe networks to ensure smooth drainage of the pipe network and reduce the risk of waterlogging.
Maoyuan Environmental Protection for Guangzhou Tianhe District to provide municipal pipe network dredging repair project, covering 200 kilometers of municipal pipe network, through intelligent dredging and trenchless repair process, a comprehensive solution to pipe network blockage, leakage, damage and other issues.
✅Project Background
Some municipal pipe networks in the jurisdiction have been built for a long time, and there are problems such as siltation and blockage, pipeline damage, leakage and so on.
✅Project Programme
- Using high-pressure water jet dredging technology, the pipe network for a comprehensive dredge, remove silt, debris and blockage.
- The introduction of CCTV pipeline inspection robot, the pipe network defects for accurate positioning, issued a professional inspection report.
- The use of UV curing non-excavation repair process, the damaged pipeline repair, without a large area of excavation of the road surface.
✅Project effectiveness
- Pipe network dredging rate of 98%, drainage capacity recovery rate of 100%
- After repair, the pipeline leakage rate drops to 0, and the service life is extended by more than 20 years.
- Preventive maintenance significantly reduced pipe network blockage and waterlogging accident rates, down 80% year-on-year.
- Trenchless construction to reduce the impact on traffic and residents' lives, construction efficiency increased by 70%
