管片检漏和抗弯抗拔试验自控系统的优化设计及应用

Optimal Design and Application of Automatic Control System for Segment Leak Detection,Bending and Pull⁃out Tests

既有预制混凝土管片的检漏、抗弯和抗拔试验装置系统控制精度差,自动化程度低,试验结果不准确,容易造成管片生产质量隐患。文章对该试验装置的整体结构受力方式和系统控制方式进行了优化设计和计算分析。优化后的预制混凝土管片检漏、抗弯和抗拔试验自控装置应用到济南黄河隧道工程中,效果显著,提高了测试精度和自动化程度;有利于预制混凝土管片检验标准的修订,为管片生产质量的提高提供了一种自动化的检测方法。

The system of the existing precast concrete segment has poor control accuracy,low automation and inaccurate test results,which is easy to cause the hidden danger of the production quality of the segments.The optimal design and calculation analysis of the whole structure stress mode and system control mode of the test device were carried out in this paper.The optimized automatic control device for segment leak detection,bending and pull-out tests has been applied to the Yellow River tunnel project in Jinan,with remarkable effect and improved test accuracy and automation.It is helpful to revise the inspection standard of precast concrete segment,and provides an automatic inspection method for improving the quality of segment production.
