How to ensure construction safety in steel construction?

d an exclusive monitoring platform for Steel Structure projects, integrating stress monitoring, wind speed warning, personnel positioning and other functions. When the wind speed exceeds grade 6, the system automatically suspends the lifting operation and issues an alarm. By implanting 386 intelligent sensors in a bridge project, real-time monitoring of stress changes in key components has successfully warned of three abnormal loading situations and avoided structural instability.

Capacity Building of Personnel to Build a Strong Safety Foundation

The company has implemented the “dual certification + annual retraining” system, requiring welders to hold both special operation certificates and AWS certificates, and lifting commanders to pass the VR accident simulation test. An assembly building project innovated the “safety point system”, where workers can exchange rewards for correctly wearing PPE and timely reporting of hidden dangers, prompting a 67% drop in the rate of unauthorized work.

The company established a three-dimensional visualization delivery system for steel structure projects, and transformed the complex node construction process into interactive animation. A metro hub project utilized AR technology to enable workers to practice the order of applying high-strength bolts in a virtual scene, and the passing rate of the training and assessment was raised from 75% to 96%. The introduction of smart helmets, with alarms for hat removal and fatigue monitoring, has corrected the behavior of unfastened seat belts for a total of 1,670 times.

Emergency management system for risk prevention and control

Prepared a special emergency plan for steel structure project, focusing on preventing 7 types of dangerous situations such as component overturning and fire. Quarterly joint drills for multiple work types are carried out to ensure that an emergency response is formed within 15 minutes. The self-propelled firefighting and rescue platform configured for a super high-rise project can reach the 200-meter working surface in 30 minutes, which is 5 times more efficient than the traditional ladder truck.

Establishing a regional emergency material sharing library for steel structure projects, and centralizing the reserve of hydraulic jacking equipment, temporary support frames and other special equipment. During the transit of Typhoon Meihua in 2023, 12 under-construction projects in the Yangtze River Delta region quickly obtained 300-ton counterweight blocks through the material transfer system, which effectively guaranteed the wind stability of the suspended structures.

Conclusion

According to the statistics of China Steel Structure Association, the safety accident rate of the industry decreased by 28% year-on-year in 2023, but fall from height still accounted for 53% of the total number of accidents. In the future, the safety control of steel structure project will show three major trends: digital twin technology to realize the risk of over-warning, modular construction to reduce the amount of work at height, and smart wearable devices to build an active protection system. Only through the deep integration of technological innovation and management innovation can we promote the safety level of steel structure project to realize a qualitative leap, and build a solid cornerstone for the high-quality development of the construction industry.
