Discussion on the scale and development trend of engineering detection industry in China On the scale and development trend of China's engineering detection industry, the scale of China's inspection industry showed a growth trend from 2013 to 2016, and all indicators achieved year-on-year growth. By the end of 2016, there were 33235 inspection and testing institutions in China, with 1.02 million employees and operating income of 206.5 billion yuan per capita [2019-03-08] View details -
Ultrasonic pile testing: detection is an effective measure to improve engineering quality The inspection work is an effective measure to improve the quality of the project. In the construction of highway bridges, the raw materials, semi-finished products and finished materials required by the project should be in accordance with the relevant test and detection procedures. In addition to routine tests, the ultrasonic pile testing indicates that in order to investigate whether the materials can really meet the construction technology requirements, it is necessary to carry out routine tests on various raw materials [2019-03-08] View details -
Discussion on the influence factors of acoustic detection Discussion on the influencing factors of acoustic testing in pile foundation quality testing with the acoustic transmission method, the acoustic time value read by the acoustic instrument may be the acoustic time value when the ultrasonic wave meets the steel bar in the propagation path of the concrete. At this time, the measured acoustic time value may be part or all of the ultrasonic transmission time in the reinforcement [2019-03-08] View details
