海南“第一长隧”鹦哥岭隧道全线贯通

Core Viewpoint - The completion of the Yinggeling Tunnel marks a significant milestone in the construction of the Shiyun to Baisha Expressway, enhancing transportation infrastructure in Hainan Province and supporting the development of the Hainan Free Trade Port [1][2]. Group 1: Project Overview - The Yinggeling Tunnel is the longest highway tunnel in Hainan, with a total length of over 8.2 kilometers, featuring dual four-lane construction standards and a design speed of 80 km/h [1]. - The project is a key control project for the Shiyun to Baisha Expressway, funded and constructed by Hainan Provincial Transportation Investment Group [1]. Group 2: Environmental Considerations - The project adheres to the "ecological priority, green construction" principle, implementing measures to protect the regional ecological environment, including a wastewater purification system and real-time noise monitoring devices [1][2]. - Efforts include full closure management of temporary sites, recycling of tunnel spoil, and the relocation and protection of precious trees, aiming for a construction model that minimizes ecological disruption [1][2]. Group 3: Technological Innovations - The construction process employs new technologies, processes, materials, and equipment, promoting full mechanization of tunnel operations and utilizing multi-source data for precise geological assessments [2]. - Advanced techniques such as digital twin modeling and rapid rock strength acquisition are applied to enhance safety and efficiency in blasting operations [2]. Group 4: Regional Impact - The tunnel's completion will improve the road network in central Hainan, accelerate the development of ecological tourism resources and specialty agricultural products, and provide new momentum for rural revitalization [3].
