How many people died in Jingguang Tunnel in Zhengzhou?

Up to now (on the evening of July 26th, 2002 1 year), in the field investigation of Zhengzhou, Guangzhou, Beijing and expressway tunnels, * * * found 6 victims, including 5 males and 5 females1person.

Jingguang tunnel:

Jingguang Tunnel is1835m. The total length of Jingguang Road Tunnel in Zhengzhou is1835m, and the total height of the tunnel is 6m. The first phase was completed and opened on April 28th, 20 12, and the second phase was completed in September, 20 17. It is a "throat" of Beijing-Guangzhou Expressway in Zhengzhou, running through the north and south. Along this road, Zhengzhou has many important transportation hubs, from Zhengzhou North Station in the north to Zhengzhou Bus Terminal in the south.

Second, Zhengzhou Jingguang Tunnel Waterlogging Event:

In the face of such a big flood, there are indeed some places where the so-called wisdom tunnel has not played a very good role, and there are indeed some places where the most basic life support effect is worth improving. In particular, taking effective measures for specific traffic projects in combination with weather forecast can also improve the disaster reduction effect in the project responsibility area. It is necessary to improve the resilience and reliability of intelligent transportation facilities, especially disaster prevention and mitigation equipment. The layout of equipment, communication and power cables and cable joints should be considered comprehensively to improve the ability to resist the influence of fire, flood and collision. It is necessary to compare and analyze the communication and power cable layout between tunnel roadside cable trench and tunnel side wall high cable trench. Cables laid in different positions should be waterproof and sealed according to different technical indexes.

In addition, for the tunnel intelligent transportation system, it is necessary to clarify what is life-saving and what is icing on the cake, and spare no effort to improve the reliability of the foundation and life-saving system. This requires that the tunnel and even the comprehensive traffic information service system must aim at the actual effect, not stay at the theoretical level, let alone pursue conceptual innovation.

Cables laid in different positions should be waterproof and sealed according to different technical indexes. Any system will have its upper limit of disaster resistance. Assuming that the expressway tunnel is low-lying, if it is completely filled with rain in the rainstorm, in this case, if the system is required to work normally, it is reluctant. But disasters often develop gradually and have a process.
