基于TRIZ钢筋套筒灌浆浆体回流问题解决策略探讨

Discussion on Solving Cementitious Grout for Rebar Sleeve Splicing Backflow Problem during Sleeve Grouting Based on TRIZ Theory

针对装配整体式混凝土结构钢筋套筒灌浆连接接头在灌浆过程中,浆体易产生回流这一施工技术难题,首先运用TRIZ理论分析问题解决流程,然后依次运用最终理想解、因果分析、资源分析、矛盾分析、物场分析及创新设计软件等工具,得到创意解。最后,对创意解进行评价,提出灌浆扩大套筒、灌浆料提前置于磁场中、超声波振动浆料、灌浆口自动封堵等一系列简单易行且值得进一步研究的解决方案,为解决浆体回流问题提供思路,同时也为TRIZ理论在土木工程领域的应用提供参考。

In response to the construction technical problem that the grout is prone to backflow during the grouting process of the steel sleeve grouting connection joint of the assembled integral concrete structure,the problem solving process is first analyzed using TRIZ theory,and then the creative solution is obtained using tools such as final ideal solution,causal analysis,resource analysis,contradiction analysis,physical field analysis,and innovative design software.Finally,the creative solution is evaluated and a series of simple and feasible solutions that are worth further research are proposed,such as expanding the grouting sleeve,placing the grouting material in a magnetic field in advance,ultrasonic vibration of the grouting material,and automatic sealing of the grouting opening.This provides ideas for solving the problem of slurry backflow,and also provides a reference for the application of TRIZ theory in the field of civil engineering.
