Soil Drainage TRIZ Cases
- Perforated Drain Pipe Installation Without Surface Excavation
A pointed perforated pipe is driven underground to drain water and inject sand-gel stabilizer, avoiding trenching, erosion, and surface damage.
- Wrapped Drainage Units for Sunlight and Heat Protection
Film that blocks UV and infra-red protects recycled polystyrene drainage units from sunlight damage while preserving uniform appearance.
- Modular Drainage Body With Nesting Spacers for Stable High-Capacity Stacking
Nesting truncated-cone spacers let modular drainage bodies stack compactly for transport yet assemble into stable, higher-capacity infiltration units.
- MMVF Drainage Binder Composition Without Formaldehyde Leaching
Oxidized lignin binders help MMVF drainage media keep strength and water retention while avoiding formaldehyde emissions and wetting-agent leaching.
- Concrete Channel Extrusion Mold for Continuous Ditch Laying
A piston-driven mold and hopper vibrator automate concrete channel forming in drainage ditches, cutting manual labor while maintaining shape integrity.
- Underground Water Barrier Plowing for Fast Sandy Soil Installation
A plowing-based film laying approach installs underground water barriers in sandy soil faster than trenching while helping retain moisture and nutrients.
- Corrugated Water Storage Chamber Flange Locking for Wall Stability
Interlocking end flanges stabilize solar-heated plastic stormwater chambers during crushed-stone installation.
- Segmental Wick Drain Mandrels for Variable Installation Depths
A shoe coupler joins reusable mandrel segments, extending wick drains beyond fixed rig lengths for adaptable depth installation.
- Drainage Anti-Slide Pipe Pile for Seepage Control in Expansive Soil
Drainage channels collect seepage behind expansive-soil channel slopes while a rock-embedded section transfers slide thrust to stable ground.
- Plastic Retention Boxes With Elastic Clip Joints for Heavy Loads
Elastic clips and non-deformable catches join plastic half-elements while internal columns support water flow under heavy loads.
- Leaching Chamber Locking Swivel Latch for Angular Alignment
Overlapping flanges and locking pins let leaching chambers follow terrain contours without external fasteners or continuous hand labor.
- Plastic Drain Sheet With Crossed Grooves For High Pressure Stability
Crossed grooves and mating grooves in a plastic drain sheet create through-openings that maintain structural stability under high pressure loads.
- Aggregate Replacement Device Radial Pipe Insertion
A permeable drainage board with a radial pipe insertion mechanism streamlines French drain assembly.
- Leaching Chamber Diagonal Ribbed Top Design
Diagonal ribs on a leaching chamber top enhance torsional stiffness, solving sidewall strength issues from infiltration slots.
- Open Channel Condition Index for Storm Water Management
A standardized channel condition index evaluates open water segments using weighted inventory items.
- Modular Drain Panels with Interlocking Tubular Supports
Segmented injection-molded panels with integrated backing grids reduce installation time and transportation costs while maintaining reliable fluid flow.
- Stormwater System Concrete Perimeter Plastic Modules
Concrete perimeter channels confine plastic modular elements to resist lateral forces, enabling deeper installation and improved accessibility for inspection.
- Multi-layer liner assembly for sand trap drainage
A multi-layer liner assembly combines a permeable geotextile fabric with an impermeable polyurea coating to manage water flow in golf course sand traps.
- Trenchless Subsurface Collector Drain for Water Table Control
A trenchless subsurface collector piping system passively draws surface and subsurface water through perforated branch pipes.
- Corrugated Stormwater Chamber Sub-Corrugation and Interlocking Design
Sub-corrugation crests and interlocking end walls resolve water dispersion inefficiency while maintaining structural strength in molded plastic chambers.
- Automated Hydraulic Spool for Drain Tile Coil Adjustment
Hydraulic actuators adjust spool size to secure drain tile coils, eliminating manual handling and reducing deployment time.
- Drainage Bead Geometries for Compressive Strength and Void Volume
Central spine and leg structures maintain compressive strength while maximizing void volume, reducing manufacturing costs associated with higher bulk density.
- Leaching Chamber Slots for Soil Intrusion Prevention
Leaching chamber slots with 0.01-0.17 inch heights prevent soil intrusion and maintain hydraulic capacity.
- Wick Drain Shoe Gasket Prevents Mandrel Contamination
A wick drain shoe gasket seals the interface between the mandrel and base portion during soil insertion.
- Perforated Canopy Leaching Unit for Shallow Trench Installation
Segmented plastic leaching unit with perforated canopy maintains storage capacity while reducing profile height for shallow trench installation.
- Arch Storm Water Chamber with Geomembrane Liner
An arch-shaped storm water chamber employs a flexible geomembrane floor liner to replace stone-filled trenches, reducing land occupation and clogging risks.
- Rectangular Mat With Barbed Prongs For Stacked Fluid Containment
Barbed prongs interlock with receptacles in adjacent mats to resist lateral forces, solving displacement issues in stacked fluid containment systems.
