Perforated French Drain Pipe with Flushing Conduits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
French drain systems often clog due to the buildup of iron ocher, a byproduct of iron oxidation in groundwater, which can lead to under-performance or failure of the drainage system.
Innovation Solution
A perforated pipe with built-in conduits for receiving pressurized wash fluid, allowing for the discharge of wash fluid both into and exterior of the pipe to flush out iron ocher from the pipe and surrounding gravel, utilizing hose fittings for connection to a water source and strategically positioned orifices to direct the flow effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional perforated pipe is used in a French drain system, then the pipe can collect and redirect water effectively, but iron ocher builds up in the pipe and perforations causing clogging and system failure
Solution Approach 1:
The patent incorporates built-in conduits with orifices during pipe manufacturing that enable preliminary and periodic flushing actions. These conduits allow wash fluid to be introduced into the pipe interior and surrounding gravel before complete clogging occurs, preventing iron ocher accumulation and maintaining drainage performance over time.
2Productivity
If the pipe is pitched to allow water flow to discharge point, then water can be redirected effectively, but iron ocher deposit builds up in the channel and perforations
Solution Approach 1:
The patent utilizes hydraulic principles by introducing wash fluid through built-in conduits under pressure. The orifices discharge wash fluid into the pipe interior and surrounding gravel, creating hydraulic flow that removes iron ocher deposits without requiring system disassembly or manual intervention.
3Device complexity
If conventional pipes without flushing capability are used, then the system structure remains simple, but removal of iron ocher requires system disassembly and manual cleaning
Solution Approach 1:
The patent merges the flushing function directly into the pipe structure by integrating built-in conduits and orifices during manufacturing. This combination eliminates the need for separate external flushing systems or manual disassembly, as the cleaning capability is embedded within the pipe itself while maintaining relatively simple overall structure.
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 solution effectively prevents clogging by regularly flushing out iron ocher, maintaining the system's performance and extending its lifespan through efficient removal of deposits without disturbing the surrounding gravel, and allows for chemical treatment options.
Implementation Method 1
a built-in conduit for receiving wash fluid; said conduit comprising an outlet for discharging wash fluid into said perforated pipe
Data Source
AI summary
A French drain drainpipe with built-in means for flushing iron ocher out of the drainpipe, out of the perforations, and out of the gravel surrounding the drainpipe. Said means may include chambers for receiving pressurized washing fluids and exit orifices from the chambers. Fittings are provided for connecting the chambers to a pressurized source of washing fluids, such as hose fittings for connecting to a normal household water supply.
