Beijing Portable DN1600 Concrete Pipeline Rehabilitation
Location: Shunyi District, Beijing, China
Asset: DN1600 reinforced concrete pipeline
Key Project Parameters & Critical Challenges
- Compact Manhole & Large Diameter Constraint: Extra-small manhole design with a 680mm diameter opening, far smaller than standard manhole specifications, posing strict access limitations for large-diameter pipeline repairs
- Deep Burial Condition: Pipeline buried at a depth exceeding 5 meters, increasing construction difficulty and operational safety requirements
- Urgent Project Timeline: Tight emergency delivery schedule requiring accelerated construction and prompt response
- Last-Minute Process Adjustment: Unplanned temporary modification to the rehabilitation technique to adapt to site constraints and meet emergency delivery targets
