Gulley With Permeable Sidewalls And High-Strength Bottom
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gullies have limited storage capacity for storm water and are prone to damage from the impacts of suction tubes during cleaning, leading to frequent replacements.
Innovation Solution
A gulley design featuring a tile-like concrete bottom with higher compressive strength than the liquid-permeable concrete sidewalls, allowing for increased water storage capacity without enlarging the gulley's outer dimensions, and enabling effective infiltration of water into the ground.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If the gulley uses liquid-permeable material for the entire structure including the bottom, then water infiltration into the ground is improved, but the resistance to impact damage from suction tubes during cleaning deteriorates
Solution Approach 1:
The patent applies different material properties to different parts of the gulley structure. The sidewalls are made of liquid-permeable material to enable water infiltration, while the bottom is made of non-permeable, high-strength material to resist impact damage from cleaning operations. This local differentiation of material properties resolves the contradiction between infiltration capability and impact resistance.
2Quantity of substance
If the gulley outer dimensions are increased to provide larger water storage capacity, then storm water storage is improved, but the space required for installation and the cost of materials increase
Solution Approach 1:
The patent utilizes porous, liquid-permeable material for the sidewalls of the gulley. This allows the gulley to store water while enabling infiltration into the surrounding ground, effectively increasing the functional storage capacity without proportionally increasing the outer dimensions. The porous structure allows water to be held temporarily while permitting gradual release into the ground.
3Object-generated harmful factors
If the liquid-permeable material is used for the entire gulley structure, then water infiltration is improved, but the lifespan of the gulley deteriorates due to frequent damage from cleaning operations
Solution Approach 1:
The patent applies different material properties to different parts of the gulley structure. The sidewalls are made of liquid-permeable material to enable water infiltration, while the bottom is made of non-permeable, high-strength material to resist impact damage from cleaning operations. This local differentiation of material properties resolves the contradiction between infiltration capability and impact resistance.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The gulley achieves a larger water storage capacity before diverting water to the stormwater sewer system, while maintaining a comparable lifespan and resisting damage from suction tube impacts.
Implementation Method 1
The sidewall is a tube-like portion of components which form a rigid wall made of liquid-permeable material

AI summary
The application describes Gulley (100) comprising a gulley pot (102) having a bottom (104) and a sidewall (106) provided with an outlet (108) for discharging liquid in the gulley pot to drain piping. The bottom (104) is a tile-like portion (104A) of concrete and the sidewall (106) is a tube-like portion (106A) forming a rigid liquid-permeable wall. Each of the tube-like portion and tile-like portion has a contact surface (106B, 104B) that connects the portions together. The tile-like portion has a crushing strength which is higher than the crushing strength of the tube-like portion.
