Underground Chambers TRIZ Cases
- Pipe Segment Coupler With Expanding Claws for Fast Longitudinal Joining
Elastic coupler claws expand through side-plate holes to clamp pipe segments quickly, replacing bolts and nuts while maintaining strong joints.
- Insulating Weld Inspection Using a Burnable Conductive Layer
A burnable conductive layer turns weld inspection in waterproofing insulation into a fast electrical check that pinpoints poor joints and adhesion.
- Cross Control Fitting Layout for Easier Concrete Line Cleaning
A retractable control member opens hard-to-reach fitting regions for sponge-ball cleaning, reducing concrete residue and downtime.
- Strap-Mesh Rockfall Panel for Energy-Absorbing Tunnel Containment
A buckle-linked strap mesh and perimeter frame absorb rockburst energy by plastic deformation while simplifying tunnel panel installation.
