Arch Storm Water Chamber with Geomembrane Liner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storm water management systems are inefficient and costly due to the use of stone-filled trenches and perforated pipes, which are prone to clogging and occupy valuable land space, and require complex and expensive piping systems for conveying storm water to drainage systems, especially when drainage systems are built away from collection points.
Innovation Solution
A modular storm water chamber system with an arch-shaped design and floor liner, featuring liquid intake openings, reinforcing members, and connector members for connecting multiple units, allowing for efficient storage and conveyance of liquids over large areas without the need for extensive piping, and can be easily installed and expanded.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If stone-filled trenches with perforated pipes are used for storm water infiltration, then water can be directed into the earth, but the system occupies substantial volume and is expensive
Solution Approach 1:
The patent employs a flexible geomembrane liner that forms the walls and bottom of the infiltration trench, replacing the traditional rigid stone structure. This thin film approach provides the necessary containment and directional control for storm water infiltration while occupying minimal volume, directly resolving the contradiction between infiltration reliability and volume occupation
Solution Approach 2:
The invention extracts and eliminates the stone component from the traditional infiltration system, retaining only the essential function of directing water into the earth through a simplified linear trench with flexible membranes. This removal of unnecessary material reduces volume while maintaining the core infiltration capability
2Reliability
If stone-filled trenches with perforated pipes are used for storm water infiltration, then water can be directed into the earth, but the system is expensive
Solution Approach 1:
The flexible geomembrane liner is a cost-effective material that replaces expensive stone and complex pipe systems. This thin film solution provides durable, reliable storm water infiltration at reduced material and installation costs, resolving the contradiction between infiltration reliability and system cost
Solution Approach 2:
By removing the stone component and simplifying the structure to a linear trench with flexible membranes, the invention eliminates unnecessary expenses associated with stone procurement, transport, and installation, thereby reducing overall system cost while maintaining infiltration reliability
3Length of moving object
If traditional piping systems are used to convey storm water to drainage systems, then liquid can be conveyed over distance, but the pipes are susceptible to clogging and require sophisticated expensive systems
Solution Approach 1:
The patent merges the infiltration function directly into the conveyance path by creating a continuous linear trench system that both transports and infiltrates storm water along its length. This integration eliminates the need for separate sophisticated piping systems and intermediate drainage structures, reducing complexity while maintaining conveyance capability over distance
Solution Approach 2:
The linear infiltration trench system is designed as a modular, segmented structure that can be easily installed in sections. This segmentation simplifies the overall system compared to complex piping networks, allowing for straightforward installation and maintenance while achieving the required conveyance distance through cumulative segment length
4Length of moving object
If traditional piping systems are used to convey storm water to drainage systems, then liquid can be conveyed over distance, but the pipes are susceptible to clogging
Solution Approach 1:
By merging the infiltration function with the conveyance path in a single linear trench system, the invention eliminates the clogging problem inherent in traditional pipes. The open-trench design with flexible membranes allows debris to pass through rather than accumulate, maintaining reliability over distance without the clogging susceptibility of enclosed piping systems

AI summary
A drainage system includes a storm water chamber and floor liner assembly for storing and conveying liquids. The storm water chamber comprises a generally elongated arch shape with an arch top and bottom side walls, thereby defining an enclosure, the enclosure having a plurality of liquid intake openings. The floor liner comprises two generally parallel sides each having a plurality of retaining members for connecting the storm water chamber. When the storm water chamber and floor liner are connected with each other, the system provides a substantially enclosed assembly for conveying liquids.
