12月15日，随着最后一方混凝土顺利浇筑到位，焦洛平高铁控制性工程——邙山隧道的盾构始发井地连 墙施工全部完成，世界最大直径土压平衡盾构隧道施工进入加速阶段。 中铁十一局有关负责人说，此次完成地连墙施工的盾构始发井是盾构机组装、调试及始发掘进的核心场 地。始发井基坑长57.9米、宽27.8米、深23.7米，围护结构由32幅地下连续墙组成，最大成槽深度达36 米。 项目建设过程中，上软下硬地层、地下水压环伺等复杂地质，给施工带来极大挑战。传统成槽工艺效率 低下，安全风险高，难以满足施工需求。为破解工程瓶颈，项目团队组建了专项技术攻关小组，经过多 轮方案论证与现场试验，创新采用"成槽机抓槽+旋挖钻引孔+冲击钻修槽"的复合循环成槽方案。该方 案有针对性地解决了上部软土地层易塌槽、下部硬岩地段成槽困难等问题，在保证工程安全质量的同 时，有效推进了施工进度。 "下一步，我们将持续梳理优化施工方案，科学协调各施工单元，确保设备无缝转换与工序有序衔接， 保证后续工程高标准建设。"现场工区经理陈建告诉记者。 作为焦洛平高铁全线长度最长且唯一采用盾构法施工的工程，邙山隧道全长6340米，由中国铁设总承 包，中铁十一局负责承建。 ...

Group 1 - The core focus of the news is on the development of high-speed rail projects in Henan Province, specifically the construction of the Huo-Luo-Ping high-speed rail segment and the Ping-Luo-Zhou high-speed rail, which are crucial for enhancing regional connectivity and transportation efficiency [1][2][3]. - The Huo-Luo-Ping high-speed rail is part of the national high-speed railway network and is a significant infrastructure project planned during the 14th Five-Year Plan period in Henan Province, with construction having officially commenced in June 2023 [1][3]. - The Ping-Luo-Zhou high-speed rail will connect several key cities, including Pingdingshan and Zhoukou, spanning a total length of 199.7 kilometers, and is expected to improve travel times significantly [1][2]. Group 2 - The completion of the Huo-Luo-Ping high-speed rail is anticipated to break the transportation barriers in the western mountainous areas of Henan, linking resource-rich cities like Jiyuan and Ruzhou, and reducing travel time between Luoyang and Pingdingshan to approximately 40 minutes [3][5]. - The ongoing construction of these high-speed rail lines is part of a broader vision for a "Central Plains Urban Circle High-Speed Rail," which aims to connect multiple cities in the region, enhancing economic integration and development [5][6]. - The concept of a circular high-speed rail network is supported by examples from other regions, such as the "Yangtze River Delta Super Ring High-Speed Rail," which has successfully connected major urban centers and promoted balanced urban development [5][6].

Core Viewpoint - The construction of the Jiaoluo-Ping High-Speed Railway (焦洛平高铁) marks a significant development in the transportation infrastructure of Henan Province, enhancing connectivity and economic growth in the region [1][16][17]. Group 1: Project Overview - The Jiaoluo-Ping High-Speed Railway is a key segment of the Hunan-Guangdong High-Speed Railway, connecting the cities of Jiaozuo, Jiyuan, Luoyang, and Pingdingshan, with a total length of 230.488 kilometers and a design speed of 350 km/h [7][17]. - The project includes the construction of five new stations and the reconstruction of existing ones, with a total construction period planned for four years [7][17]. Group 2: Economic Impact - The railway is expected to significantly enhance the economic landscape of the western Henan region, facilitating the integration of various industries and resources, and creating a "two-hour industrial collaboration circle" that connects with neighboring provinces [14][18]. - The project is projected to improve supply chain response times by 40% for key industries in Luoyang, Pingdingshan, and Jiyuan, thus stimulating regional economic development [14][18]. Group 3: Transportation Network Enhancement - The Jiaoluo-Ping High-Speed Railway will fill the gap in the vertical high-speed rail network in western Henan, transforming the transportation framework from a single-center model to a multi-hub network [17][18]. - The railway will connect with existing lines, enhancing the overall capacity and efficiency of the high-speed rail network in the province [17][18]. Group 4: Cultural and Tourism Development - The railway is anticipated to boost tourism by improving access to cultural sites, such as the Longmen Grottoes, and promoting a "high-speed rail + cultural tourism" model [6][13][18]. - Increased connectivity is expected to attract more visitors from surrounding regions, thereby enhancing local hospitality and cultural industries [12][13].
