Testing Technology for Grouted Density and Empty Hole of Prestressed Corrugated Pipe Based on Ultrasonic Wave Qingzhou Wang 1,2,a, Hao Qian 1，b, Shibin Ma 1,2，c, Tengfei Ma 1，d 1Institute of Civil Engineering, Hebei University of Technology, Tianjin 300401, China 2 Civil Engineering Technology Research Center of Hebei Province, Tianjin 300401, China awqz1718@126.com,b573154388@qq.com, c286563105@qq.com, d279914585@qq.com Keywords:corrugated pipe; ultrasonic wave; empty hole; detection Abstract: In order to explore detecting function for grouted density and empty hole of corrugated pipe, the paper proposes a method.
According to the above test data,the phonation time of concrete area is smaller than the phonation time of dense area,while the volatility of concrete is biger than the Volatility of hole area.The reason is that wave will scatter, reflect and lose a part of the energy,when it meet with corrugated wall in spreading process.As a result, phonation time and volatility can be chosen as determining test site parameters in the practical engineering detection. 4 Conclusion Through to a series of nondestructive testing and the analysis of test data analysis in the default defect prestressed corrugated pipe, finally the result is consistent with the set of actual situation, thus get the following conclusion.
Based on analysis of ultrasonic data,we found that the larger phonation time or smaller volatility apper at empty area, and phonation time would be smaller or volatility would be larger in the dense area and concrete area , mainly because of ultrasonic diffraction happens on the hole area.To locate grouted defect in corrugated pipe though the difference between phonation time and volatility,phonation time and volatility can be chosen as determining test site parameters in the practical engineering detection.

In this work, we analyze the behavior of NiTi wires intended for use as dampers in Civil Engineering or as actuators.
The 2.46 mm diameter NiTi wire is intended for practical use to build dampers in Civil Engineering, as the forces it can support in transforming are in the range 1-3 kN, while the thinner wires, suggested for use in small actuators, have been included for comparative purposes.
