Ground-Work TRIZ Cases
- Drainage Channel Functional Region With Fine-Resin Sealing Surface
A fine-filled reaction resin in the channel’s functional region creates a smooth, low-pore sealing surface without added coating steps.
- Hydraulic Winch Scraper for No-Entry Culvert Clearing
A hydraulic winch, pulley, and toothed scraper remove culvert debris bidirectionally without personnel entering confined spaces.
- Roll-Formed Reinforcement Rib for Overhead Structures
Replacing extrusion with roll-forming, the nested rib design reduces manufacturing costs while maintaining structural integrity for large spans.
- Pre-stressed Box Culvert Segmentation for Long Spans
A pre-stressed concrete box culvert divides into three-sided segments with male and female connectors to enable longer structural spans.
- Culvert Ditch Transitioning Device Embankment Lining
Panel lining eliminates lawn care maintenance by stabilizing culvert ends and side embankments with textured surfaces.
- Drainage Insertion with Vertical Anchor Plate for Slope Stability
Vertical ground anchor plate stabilizes concave tray insertion, preventing pipe damage from mowing and vegetation obstruction.
- Knitted Geotextile With Capillary Yarns for Roadway Drainage
A knitted geotextile uses capillary active yarns to transport fluid through layered strength and knitting yarns.
- Pre-sloped Modular Trench Drain for Level Installation
Modular trench sections with pre-sloped interior channels enable gravity drainage in level trenches without custom excavation.
- Culvert Pipe Inlet With Nested Frictional Sleeve
A nested inlet sleeve prevents slope erosion by eliminating gaps between the pipe and end sections.
- Precast L-Wall Stormwater Detention System
Segmented precast L-wall and double-T assemblies reduce excavation labor while increasing detention capacity.
- Hinged Plastic Stormwater Chamber Segmentation
Segmented plastic stormwater chambers use fusion welding at a hinge joint to reduce injection molding costs and improve shipping efficiency.
- Basalt FRP Rebar Corrosion Resistance in Concrete
Basalt fiber reinforced polymer rebar eliminates corrosion risks while maintaining structural integrity and bond strength.
- Road Structure Reconstruction Using Segmented Underground Garage Design
Segmented road structure reconstruction preserves underground garage roof plates using layered construction and lightweight materials.
- Box Culvert Assembly Pivoting Mechanism for Leak-Free Sealing
Pivoted box culvert assembly joins segments via angled ledges, preventing dirt accumulation and leakage caused by ground sliding during installation.
- Trench Drain Alignment Bracket for Precise Section Joining
Alignment bracket connects adjacent trench drain sections using guide pins and fasteners to eliminate manual measurement during installation.
- Drainage Grate Transition for Synthetic Turf Anchoring
Concrete anchors poured into the channel replace decomposing wood, eliminating warping and reducing installation time.
- Culvert Marker With Wire Rope Deflection
A culvert marker uses a wire rope to support a mast that deflects under lateral forces.
- Segmented Pavement Drain with Central Aperture and Debris Plate
Segmented drainage units match paver gaps to eliminate cutting, while a protective plate prevents debris entry into the central aperture.
- Culvert Air Vent Pressure Equalization
Air vent system equalizes gas pressure between culvert interior and atmosphere, preventing fluid flow restrictions.
- Modular Storm Water System Using Corbel Columns
Connecting columns with corbels support slabs to create segmented flow paths that reduce urban runoff contamination while maintaining construction efficiency.
- Dome Stormwater Chamber with Continuous Curvature
Continuous curvature distributes dead and live loads, eliminating internal supports that reduce void space for stormwater storage.
- Underdrain Gas-Liquid Distribution for Filter Media
A gas-liquid distribution technique uses concurrent flow through underdrain blocks to move air and water evenly across filter media.
- Precast Concrete Culvert with Tapered Walls and Haunches
Tapered side walls and optimized haunch thickness resolve the trade-off between hydraulic opening area and structural bending moment.
- MMVF Drain Elements for Surface Water Management
Porous expanded metal drainage elements replace gravel systems to prevent soil contamination while maintaining high buffering capacity.
