High -speed construction depends on Henan

Henan Daily client reporter Song Min

The raw materials entering the field are automatically collected relevant information from the floor -in system, and self -inspection and sampling inspection in accordance with the prescribed frequency to ensure the quality and traceability of the raw materials; Monitoring and strengthening the control of concrete process; in the construction of prestressed tensile stroke, integrated intelligent tensor stroke grown system to achieve real -time tracking, intelligent control, and timely error correction to ensure the safety and durability of the bridge structure ...

Under the wave of digitalization, how can high -speed construction be more "smart"? The reporter recently interviewed the Xixia -Xichuan section (hereinafter referred to as the West Pyrodia Expressway) from the Ekang to the Xichuan Expressway. The project fully applies the comprehensive information management platform, realizes the entire process of engineering construction, and continues to accelerate the construction progress to ensure that this year's high level is completed and opened to traffic. Essence

On August 26, at the construction site of the Zhangwante Bridge in the west highway, a large pavement machine, 5 pressure road machines, and 5 transport vehicles were undergoing asphalt paving in the middle of the road to crush the construction. Unlike the traditional construction of workers, the paving crushes more with the help of digital power, and can monitor the relevant parameters on the site on the mobile side of the mobile phone.

"In the past, the speed of crushing and the paving speed were mastered at the foot of the construction staff, and it was too slow to run and could not trace back. Use sensors to collect temperature, vibration frequency, acceleration and other construction parameters and upload them to the management platform to achieve real -time on -site control, remote monitoring and data analysis. Sun Lu, the person in charge of the project.

The total length of the West Pyramid Expressway is 52.76 kilometers. It is one of the 12 north -south vertical lines of the province's highway network adjustment plan. The starting point is located at the Shanghai -Shaanxi highway. Essence The project has 46 bridges and 6 tunnels, and the bridge -tunnel ratio is 50.91%. After completion, it will greatly improve the traffic conditions in the southwestern Henan mountainous areas. It is a "enrichment road" for promoting tourism and mining resources along the route and driving the development of southwestern Henan.

Coming to the operating surface of the 3553 -meter -long tunnel, the widening section of 1500 meters from exports, the workers are undergoing two -lining and tunnel road construction, and an engineering vehicle passes through the tunnel from time to time. "The biggest difficulty of the tunnel lies in the shallow buried construction, through local roads, only 7.2 meters from the bottom of the river valley, the surrounding rock is easy to weather, and there are residential houses near the excavation range." Deputy President Shi Fuchun said that in order to prevent the collapse of rocks and the loss of surface water, mechanical excavation and controlling the blasting method, follow the principle of "short -scale ruler, less disturbance, strong support", the shallow burial section of 180 meters is full construction for 6 months for 6 months for 6 months for 6 months for 6 months. Only safely.

"During the project construction process, we always focus on the core of the" Quality Engineering ", creating an informationized comprehensive management platform based on BIM+GIS technology. Through the Internet of Things, cloud computing, big data and other means The process is intelligent and supervised, and a huge database is established to lay the foundation for the construction, management, and supporting 'integrated smart high speed. "Wang Jie, deputy minister of the Quality Supervision Department of the West High Speed ​​Project Company, said.

Material management, process reporting, hidden danger investigation, test management and control ... data supervision and digital empowerment ensure that key data cannot be changed and marks are left at the management process. At present, the 12 digital management systems created by the project have been piloted by Henan Transportation Investment Group The high -speed construction projects are fully promoted and applied.
