PROJECT TOPICConstruction, Infrastructure & Maintenance
Pipeline Crack Sealing Crawler
A trenchless utility maintenance concept exploring articulated in-pipe crawlers, rotary pneumatic grinding spindles, and dual-cartridge epoxy resin dispensers to seal internal pipe fractures without excavating roads.
Trenchless Underground Utility Rehabilitation
- ✓Repairs subterranean pipe cracks from the inside out without roadway excavation.
- ✓Prepares damaged pipe walls with motorized pneumatic rotary grinding before resin application.
- ✓Dispenses fast-curing two-part epoxy resin directly into fracture seams.
The Engineering Challenge
Problem / Objective
Repairing leaking underground drainage or sewer lines traditionally requires tearing up active city roads and disrupting traffic.
