Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional anti-seepage wall construction technologies cause significant disturbance and damage to soil embankments, are costly, and have long construction periods, making them unsuitable for small projects due to large equipment requirements and inefficiencies in material usage.
Innovation Solution
A thin-slotting lifting synchronous grouting device that integrates slotting and grouting processes, using thin cutting plates and a hollow force-bearing column with a feeding pipe and spraying device, minimizing soil disturbance and material consumption, and allowing for the construction of continuous, uniform anti-seepage walls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional anti-seepage wall construction technologies (slotting, stirring, spraying, vibrating independently) are used, then anti-seepage walls can be built, but the equipment is too large for small embankments and causes great disturbance and damage to the embankments
Solution Approach 1:
The patent combines slotting, spraying, and grouting operations into a single integrated device that performs all functions simultaneously through one insertion hole, eliminating the need for multiple separate operations and reducing disturbance to the embankment structure
Solution Approach 2:
The device is designed as a compact, modular system that can be inserted through a small hole and performs multiple functions within a confined space, making it suitable for small embankments where large equipment cannot be deployed
2Reliability
If conventional anti-seepage wall construction technologies are used, then impervious bodies can be formed in soil, but the construction period is long and the cost is high
Solution Approach 1:
The device enables continuous operation by performing slotting, spraying, and grouting in one continuous process without interruption or repositioning, significantly reducing construction time compared to sequential operations
Solution Approach 2:
The device pre-forms the slot and delivers grouting material simultaneously in the same operation, eliminating the need for separate preparation and execution phases
3Reliability
If conventional anti-seepage wall construction technologies are used, then anti-seepage walls can be built, but the equipment is expensive and inconvenient
Solution Approach 1:
The single device performs multiple functions (slotting, spraying, grouting) that previously required separate equipment, reducing overall equipment cost and simplifying operation for a single operator
Solution Approach 2:
The device is designed to be self-contained with all necessary components integrated, requiring minimal external equipment or personnel for operation
4Reliability
If conventional technologies form impervious bodies through independent slotting, stirring, spraying and vibrating, then anti-seepage walls can be built, but great disturbance and damage occurs to the embankments
Solution Approach 1:
By combining slotting, spraying, and grouting into a single simultaneous operation, the device minimizes the number of times the embankment structure is disturbed, reducing cumulative damage to the soil mass
