1. Complex environmental conditions: Involves multiple transportation facilities (railways, highways) and water bodies, posing significant challenges for construction coordination;
2. High urgency for emergency repairs: As a critical emergency repair project, restoration must be completed within an extremely tight schedule;
3. Coastal terrain adaptation: Requires addressing construction variations across three distinct topographical tiers: mountainous, flat, and coastal.
1. Completed the repair of a 2.6-kilometer main water supply pipeline in just three days, setting a new benchmark for emergency repair efficiency;
2. The entire construction process caused no disruption to residents or industrial operations along the route;
3. Served as a model case for trenchless repair in complex crossing scenarios in coastal areas;
4. Received extensive coverage and promotion by local official media, enhancing industry influence.
