Shanghai Yangtze River Bridge Modal Force Test

Before the bridge's use in 2011, Tongji University conducted modal experiments using DE5907A, confirming the design's frequency and vibration. DE5906B tested the cable tension, matching the design calculations, ensuring the bridge's safety.

Shanghai Lupu Bridge is the world's first steel structure arch bridge. After the completion of the bridge, SE-860 was used to evaluate its performance about the bridge static load.

Guizhou Qianzhong Reservoir Gate Test

We tested the time-averaged and pulsating pressure of the radial gate under various operating conditions to analyze its safety, providing data for rational gate operation.

Qingdao Cross-Sea Bridge Test

We conducted dynamic and static tests, along with sports car and modal experiments. Despite the long testing period and large data volume, our company efficiently processed and analyzed the data to successfully complete the task before the bridge's opening.

West-East Gas Pipeline Pigging Monitoring
Using the DE-944 system and sensors, we monitored pipeline pressure and diameter during the pigging process. Remote monitoring ensured safety, providing real-time data to prevent accidents and ensure smooth completion.

Three Gorges Cofferdam Blasting Test

After the completion of the Three Gorges Dam, the cofferdam was demolished. The explosion created a water hammer wave impacting the dam, requiring monitoring of vibration and displacement data before and after the blast to assess the effect.

Shanghai Expo Axis Online Monitoring
Tongji University used the DE-944 system for long-term online monitoring of vibration, wind speed, and pressure on the Expo Axis, ensuring structural safety throughout the event.

Beijing-Shenyang Line Construction

Blasting in complex terrains near cultural relics required vibration monitoring. Using the DE-884U system and DH610 sensors, vibration data was collected to assess the impact on surrounding structures, ensuring safety and progress.

Load Test on Wuyi Flyover, Anshan City

In July 2016, DE-944 and WZ-88S were used to conduct a load test on the Wuyi Flyover. The test measured strain, displacement, counterforce, and inclination to assess the bridge's design, construction quality, and carrying capacity. The results provided crucial data for evaluating the bridge's safety and guiding future maintenance and reinforcement.

PetroChina Pipeline Explosion Test

On Dec 30, 2015, China’s first full-scale pipeline explosion test was conducted in Hami, Xinjiang, under extreme conditions. Over 600 synchronized channels captured data in real time, using Dynatronic’s equipment. The test provided crucial insights for improving pipeline safety and rupture control.

Hong Kong-Zhuhai-Macao Bridge Buried Pier Installation

On June 20, 2013, the first integrated buried pier was successfully installed. Strain gauges monitored cable forces during lifting and alignment. The installation met strict verticality requirements (0.014–0.019), ensuring precision and structural stability for future bridge construction.
