Automatic collection and upload, real-time monitoring of construction sites and other functions, project management has successfully transformed from "managing affairs" to "managing data". Combined with the implementation of reconstruction and expansion construction, the project promotes the application of the intelligent ice and snow melting system, realizing the melting of small snow and easy clearing of heavy snow, which greatly guarantees the safety of road traffic in winter; at the same time, the intelligent transformation of toll stations along the line has been carried out, and the Gushan Mountain has been constructed with high quality. The smart demonstration station has greatly improved the traffic efficiency and enriched the connotation of smart expressway construction.
Keep improving to create a road of quality
As the first batch of "Ping An Centennial Quality Project" to create a demonstration project of the Ministry of Transport, the reconstruction and expansion project of the Jitai section of Beijing-Taiwan Expressway adheres to the narrow and tight roadbed, the smooth and compact pavement, and the physical appearance of bridges and culverts. The "five solids" concept of solid and solid disease treatment and durable and solid traffic safety facilities will continue to improve the level of specialization, standardization, refinement, informatization and standardization of engineering quality management, and strive to create "high-quality and durable, safe and reliable, economical and environmentally friendly, "Socially Recognized" brand of Beijing-Taiwan Jitai Reconstruction and Expansion Project. During the construction of
, the reconstruction and expansion project of the Jitai section of Beijing-Taiwan Expressway strictly implemented the "first-item approval system", from the approval, implementation, summary of the construction plan to the preparation of the work instruction, to achieve a standardized and orderly, promote the superior and discard the inferior, and effectively Guide subsequent construction. The project has completed more than 120 first construction projects, and compiled more than 60 work instructions. At the same time, the project attaches great importance to standardization construction, and implements the "44654" quality control system across the entire line, requiring all participating units to strictly follow the "Highway" of Shandong Expressway Group.Standardized Technical Guidelines for Highway Construction and industry construction technical specifications to carry out operations, leading to a steady improvement in the construction quality of the entire line.
is to build the safety management system , and the project has built a "first-line, dual-base, and five modernizations" safety management model. The typical practice is promoted by Shandong Provincial Department of Transportation as a benchmark in the province; in the process of creating a safe construction site The "124" safety inspection system has been established, and more than 300 safety hazards investigation activities have been carried out, and more than 60 safety drills and safety competitions have been organized.
