Solution Overview
Problem
Current methods for high-pressure non-destructive water excavation generate a heavy liquid content slurry that requires specialized tankers for disposal, leading to high transportation costs and potential inefficiencies in water usage.
Innovation Solution
A water separating residue filtration unit with a container and mesh screen system, utilizing a fabric filtration liner to separate water from the slurry, allowing filtered water to be recycled and reducing the weight of residual content for cost-effective transportation on conventional flatbed trucks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If specialized tankers are used to transport slurry, then the slurry can be transported, but transportation costs increase
Solution Approach 1:
The invention extracts and removes water from the slurry using a filtration system, separating the liquid content from the residue. This reduces the volume and weight of material that needs to be transported, thereby reducing transportation costs while still being able to dispose of the residual content.
Solution Approach 2:
The invention changes the physical state and composition parameters of the slurry by filtering it through a mesh screen and fabric liner, transforming it from a liquid slurry into a drier residue. This parameter change allows standard trucks to transport the material instead of requiring specialized tankers.
2Loss of energy
If water is separated from slurry, then transportation costs reduce, but water may be wasted
Solution Approach 1:
The invention recovers the separated water through collection hoses that channel the filtered water back into the excavation site where it can be reused. This prevents water wastage while still achieving the weight reduction necessary for cost-effective transportation of the residual content.
Solution Approach 2:
The system implements a feedback loop where the filtered water is collected and returned to the excavation process. The collection hoses connect the drain to the excavation site, creating a closed-loop system that recycles water and reduces the need for additional water input.
3Adaptability or versatility
If conventional flatbed trucks are used instead of specialized tankers, then transportation flexibility improves, but the trucks cannot handle wet slurry
Solution Approach 1:
The invention extracts water from the slurry before transportation, leaving only the drier residual content. This transformed material can be loaded onto conventional flatbed trucks that are not designed for wet slurry, thereby increasing transportation flexibility and vehicle versatility.
Solution Approach 2:
The filtration system performs preliminary processing of the slurry by removing water before the material is loaded for transportation. This preliminary action prepares the residue for transport on standard vehicles, avoiding the need for specialized tankers and improving logistical flexibility.
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 reduces transportation costs by separating water from the slurry, allowing for the use of standard trucks and recycling of filtered water, thereby minimizing water wastage and optimizing excavation processes.
Implementation Method 1
The liquid content of the slurry seeps through the fabric filtration liner and the screen into the void and exits the drain
Implementation Method 2
residual liquid content slurry sucked during high-pressure non-destructive water excavation can be pumped into the container and allowed to settle

AI summary
A water separating residue filtration unit has an outer container has container walls surrounding a container floor. A screen is located within the container, the screen having a screen floor supported above the container floor thereby defining an inner void between the screen floor and the container floor and at least one drain drains from the inner void and an exterior of the container. A fabric filtration liner covers the screen. Non-destructive high-pressure water excavation residual liquid slurry may be pumped into the unit, allowed to settle such that water filters therefrom through the fabric filtration liner and the screen whereafter the unit having residual content therein may be transported for dumping.
