Bulkheads/Piles TRIZ Cases
- Helical Blade Plugging Device for Micropile Grout Sealing
A helical blade plugging device anchors into borehole soil to provide immediate mechanical sealing during micropile construction.
- Automated Foundation Driver Stall Detection and Mitigation
A rotary driver uses hydraulic pressure monitoring to detect drill stalls in automated foundation assembly machines.
- Integrated Brace Connector for Manufactured Building Foundations
An integrated connector resists lateral and longitudinal wind forces without altering support beams, merging vertical bracing into a single unit.
- Soil Nail Coupler Projections for Centering and Bonding
Radially extending projections on a soil nail coupler center the member within drilled holes while expanding surface area for improved grout bonding.
- Planar Anchoring Member Curved Contour Manufacturing Cost
A planar anchoring member with a curved contour and elliptical passage enables simple press production.
- Pile Joint Locking Mechanism With Guidance Pipe
A pile joint coupling system uses a guidance pipe to align transverse holes for precise locking pin insertion.
- Mechanical Hammer Rack and Pinion Drive Low Clearance
A mechanical hammer replaces gravity operation with a motor-driven rack and pinion system, enabling consistent impact energy in confined spaces.
- Deformable Hose for Jet Grouting Depth Monitoring
Replacing rigid rods, a flexible hose records pressure shifts to monitor jet grouting at depths exceeding five meters without signal distortion.
- Precast Concrete Foundation Anchoring via Solidifying Backfill
A precast concrete foundation anchors into ground using a solidifying backfill material and filler layer to secure the structure.
- Low Poisson's Ratio Pile for Underwater Noise Reduction
Geometric features and isolation structures reduce sound coupling to water and sediment, mitigating wildlife harm.
- Anchor Reinforcement Apparatus Centering and Friction
A multi-purpose anchor reinforcement apparatus uses fixed wings with vertical slits to center the cable and increase frictional resistance.
- Double-Walled Pile Silencer Air Gap Noise Reduction
An air gap between concentric tubes blocks sound propagation from the pile to water without increasing required hammer blows.
- Anchor Arrangement with Internal Fixing for Rock Bolts
An anchor arrangement uses an internal fixing arrangement to secure an elongate body within a rock hole.
- Threaded Ground Inclusions for Load Distribution
Threaded inclusions distribute loads while preventing ground heave during installation.
- FRP Shell System for Encapsulating Piles Below Ground
An FRP shell system with an auger annulus eliminates excavation by driving the structure into the ground, reducing installation complexity and cost.
- Gyroscopic Drill String Monitoring for High-Pressure Injection Body Precision
Gyroscopic sensors on the drill string detect movement direction during injection medium ejection to determine output orientation.
- Underpinning Pile Assembly with Nested Steel Pipe and Concrete Segments
Nested steel pipes inside concrete segments resolve corrosion and torque contradictions while enabling deeper penetration into dense soils.
- Diesel Hammer Guide System with Detachable Channel Adapters
A diesel hammer guide system uses detachable channel adapter assemblies to adjust spacing distances for different support structures.
