The helmet equipped with a positioning chip, high-definition camera 24 hours real-time monitoring, advanced geological forecasting monitoring ... ... this morning, the author saw in the construction site of the Chengjiagou tunnel of the Qinhuangdao section of the Chengqin expressway, a modern technology means applied to the safety management In the past, safety ropes were attached to the lives of the front line workers. Bridge and tunnel ratio up to 45% safe production is facing severe test Chengqin Expressway is the first line of “Five Vertical and Six Horizontal Lines†in Hebei Expressway Network, and is also an important part of the road network planning of Qinhuangdao and Chengde. “The Qinhuangdao-Qinhuangdao-Qinhuangdao route has a total length of 99.2 highways. There are 69 bridges and 17 tunnels across the board. The ratio of bridges to tunnels is as high as 45%.†Long Xiutang, project manager of the Qinhuangdao section of Chengqin expressway, stated to the author. As the project is located in the hilly area, the terrain conditions are complex and the technical difficulty is high. There are many safety risks in the construction, both the risk of the surrounding rock in the tunnel excavation road and the risk of high-altitude operations in the bridge construction. There are also great risks in the construction of high-filled and excavated roadbeds and the stability of high slopes. Positioning chip loading helmet workers distribution see "big screen" “This is a helmet with a positioning chip. As long as the wearer enters the tunnel, his identity and location can be displayed on the 'big screen' at the tunnel entrance.†Yang Yongzhan, deputy section chief of the Engineering Department of Chengqin Expressway Construction Department said. Electronic screen display data information Yang Yongzhan said that it is the safety management system for the construction workers installed in the tunnel. The system can carry out identification and dynamic monitoring of the construction personnel behind the tunnel, and through automatic alarms, prevent outsiders and people without helmets from entering the tunnel. The LED display at the tunnel entrance displays the construction personnel in the tunnel in real time and in groups, making it easy for inspectors to check the movement and distribution of construction personnel in the tunnel at any time. At the same time, by monitoring the network, it is ensured that the project department 4 kilometers away from the tunnel can keep abreast of the dynamics of the construction personnel in the tunnel. It is truly that all personnel entering and exiting the tunnel are fully recorded by computers, ensuring the safety management of construction personnel. 24-hour real-time security monitoring via 3G network At the construction site of the No. 11 tender section of the Qinhuangdao section of the Chengqin Expressway, the author saw the surveillance camera at each tunnel entrance and bridge construction site. According to reports, the bid section realized 24-hour real-time monitoring through a remote monitoring system. These cameras can be zoomed in high-definition and rotated 360°. The Qinhuangdao Expressway Construction Office, the Office of the Superintendents Office, and the project department can all be viewed via the 3G network to supervise the safety production and project quality. The monitoring records will be saved and can be viewed at any time. Safety helmet mounted positioning system Preceding Geological Forecast Monitoring Finds Dangerous Persons Evacuate Immediately In order to effectively prevent the occurrence of accidental accidents, before the tunnel excavation in the 11th section of the Qinhuangdao section of the Qinhuangdao Expressway, the surrounding rock in front of the face is detected by advanced geological prediction. Forecast conditions, strengthen monitoring and inspection, and strengthen support if necessary. During the monitoring process, when abnormal or sudden changes were found in the measured data and abnormal cracks occurred on the excavated surface or on the surface of the cave, the personnel were immediately evacuated. In response to unexpected safety incidents, the bid section also set up an emergency rescue escape channel at the tunnel face, and stored rescue items such as food, water, and emergency lighting in the escape channel, and at the same time, reserved emergency emergency supplies within a safe distance.
