Sanjiang fully protects the "sea dragon"

With a total length of 55 kilometers, the Hong Kong-Zhuhai-Macao Bridge is the most technically complex and most difficult "super project" in the history of Chinese bridge construction. The land transportation time between Hong Kong and Zhuhai has been shortened from the original 3.5 hours to 30 minutes, which greatly improves the efficiency of commuting and promotes more efficient circulation and intensive deployment of economic factors.


The artificial island of the Zhuhai-Macao Port is one of the most important supporting projects of the Hong Kong-Zhuhai-Macao Bridge with the largest reclamation area. It plays an important role in connecting the main project of the Hong Kong-Zhuhai-Macao Bridge with Zhuhai and Macau. The two border crossing ports are set up on the island. Realize "city transit". After completion, it will become a regional transportation hub and a multi-functional urban complex integrating travel inspection, cargo inspection, comprehensive commerce, business support, and logistics support.


As one of the few national brands selected for the fire protection project at Zhuhai Port, the gas extinguishing system independently developed by Sanjiang has been fully applied in the project. The system is deeply integrated with dedicated fire alarm and fault signal active upload technology, which increases the response time of the host to 2 seconds, and leads the industry in terms of safety performance; on the other hand, the wiring design of the non-polar two buses also provides a link for the system construction great convenience.

In addition, as the artificial island is located in the southern subtropical maritime monsoon climate zone, the climate is complex and changeable, and the typhoon weather is frequent, the system meets severe challenges in terms of stability and reliability.Fanhai Sanjiang gas extinguishing system adopts fuzzy control theory to avoid the occurrence of false alarms and false alarms. The system has excellent stability performance. Through high-performance products and technical solutions, as well as high-standard and high-demand product manufacturing processes, the adverse effects of the complex environment of high temperature, high humidity and high salt in Lingdingyang are effectively reduced.

After the Hong Kong-Zhuhai-Macao Bridge is officially put into use, Sanjiang will provide important safety guarantees for vehicles, passengers, and goods passing through the Zhuhai Port, and will spare no effort to guard this "sea dragon".
