Demo location 1:The intersection of Bigo Road and Sports Park Road (Xinguang Branch)

Pipeline problem: The 400mm horizontal pipe is completely blocked, the upstream water level is high, and the downstream manhole observes no water flow. Previous attempts to use conventional models could not dredge.

Construction process: Using Wellcome dredging vehicles and special nozzles to puncture and dredge the blockage points. After dredging, obvious water flow can be seen downstream, and the upstream water level has dropped significantly.

Construction time: 1 hour (excluding preparation and rest time)
