Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing grouting methods face challenges in ensuring deep penetration and uniform distribution of reinforcing materials into ground pores and fine cracks due to rapid curing and fluidity deterioration, leading to inadequate reinforcement of structures.
Innovation Solution
A grouting apparatus that incorporates vibration wires tightly coupled to injection pipes, generating vibrations to enhance the penetration force and fluidity of reinforcing materials, allowing for deeper and more uniform injection into boreholes and cracks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If reinforcing material is injected only depending on pressure, then injection force is sufficient, but fluidity deteriorates rapidly and penetration depth is limited
Solution Approach 1:
The patent introduces a vibration wire coupled to the injection pipe that generates mechanical vibrations during reinforcement material injection. This vibration prevents rapid fluidity deterioration by keeping the material in a more fluid state, enabling deeper penetration into ground pores and fine cracks while maintaining sufficient injection force through the combined effect of pressure and vibration.
2Force
If reinforcing material is injected at high pressure, then penetration force increases, but uniform distribution into pores and fine cracks is compromised
Solution Approach 1:
The vibration wire generates mechanical vibrations that accompany the high-pressure injection process. These vibrations help distribute the reinforcement material uniformly into pores and fine cracks by preventing material segregation and ensuring consistent flow patterns, thereby achieving both deep penetration and uniform distribution simultaneously.
3Length of stationary object
If vibration wires are coupled to each injection pipe, then penetration depth improves, but device complexity increases
Solution Approach 1:
The vibration generating unit is designed as a separate modular component that can be coupled to multiple injection pipes through standardized vibration wire connections. This multi-functional design allows a single vibration generating unit to serve multiple injection operations, improving penetration depth across different boreholes while avoiding the need for separate vibration systems for each pipe, thereby controlling overall device complexity.
