The company was invited to participate in the "2019 China Railway Second Bureau Test Work and Testing Technology Exchange Conference"

On November 28, our company was invited to participate in the "2019 China Railway Second Bureau Test Work and Testing Technology Exchange Conference" held in the Guizhou Section of the Guizhou Railway Engineering Bureau's Guizhou Section of the China Railway Second Bureau. Problems; further strengthen the management of experiments; improve the technical level of experiments and testing, about 60 leaders and business backbones attended the meeting.

 

 

 

On the morning of the 28th, the lectures for experts and the exchange of testing technology were conducted. Professor Wu Jiazhen, the chairman of the company, and Luo Jiming, a technical engineer, made a report.

On the afternoon of the 28th, I went to the construction site of the Xinmazhipu Tunnel entrance construction site of the Guizhou Section of the Guizhou Railway Engineering Department of the China Railway Second Bureau to carry out physical inspection and comparison, and did audio frequency inspection of tunnel lining, concrete strength test, CT test of bridge pier, especially tunnel lining Audio frequency detection and geological radar have better detection effect during verification. The tunnel lining audio frequency detection technology uses a non-contact signal acquisition method, which eliminates the resonance frequency caused by the contact and improves the test stability, repeatability and reliability. The analysis method of the IE method is used to improve the detection capability of the structure. And applicable scope; the identification of the test result graph is simple and clear. This technology has good complementarity with the geological radar and has been unanimously approved by the personnel present.

 

 

 

 

 

 

 

This meeting carefully analyzed the problems in project construction quality and test and inspection, learned successful experiences, and promoted advanced information management methods to further improve the test and test technology level, quality control level and management and control capabilities of engineering projects.
