Core Viewpoint - The collaboration between China and Algeria has led to significant advancements in railway construction, showcasing the strength of Chinese enterprises in overseas projects and contributing to the high-quality development of the Belt and Road Initiative [1][11]. Group 1: Project Achievements - The Algeria Western Railway Mining Line project, a joint effort between China Railway Construction Corporation (CRCC) and Algerian state-owned enterprises, involves the construction of a 575-kilometer new route, marking it as the largest single project undertaken by Chinese companies in Algeria [2][13]. - Over 24 months, the project achieved the construction of 575 kilometers of track, produced 1.1 million sleepers, and laid 580 kilometers of rail, completing the track ahead of schedule by three months [4][15]. - The project set several records, including the highest daily earthwork volume of 100,000 cubic meters and the construction of Africa's longest heavy-load railway bridge [4][15]. Group 2: Technological Innovations - The project introduced advanced construction techniques, such as the CPG500 long rail laying machine, which successfully laid rails up to 504 meters in length and achieved a daily welding rate of 4 kilometers [4][15]. - A modern intelligent sleeper factory was established, capable of producing 5,200 sleepers per day, and a fixed flash welding line was built, achieving a maximum of 180 welds per day [4][15]. - The project developed Algeria's first desert heavy-load railway track technology system, integrating Chinese standards with local conditions to create a sustainable technical solution [7][18]. Group 3: Training and Capacity Building - The project has contributed to the training of a significant number of technical professionals in Algeria's industrial manufacturing sector, setting a benchmark for large infrastructure projects in desert regions [6][17]. - The collaboration has fostered a deeper understanding of Algeria's railway technology system, leading to the successful design and certification of prestressed concrete sleepers that meet international standards [10][21].

新华财经达累斯萨拉姆10月7日电(记者华洪立)由中国土木承建的坦桑尼亚中央线米轨铁路轨枕厂近 期顺利建成,即将全面投产。该轨枕厂占地4万平方米,建成一条预应力混凝土轨枕生产线,设计日产 量可达2400根,并配套10万根轨枕存储能力,可充分满足大规模铁路施工的连续供应需求。 中土相关负责人告诉记者,作为该国首个米轨混凝土轨枕厂,项目的落成不仅填补了坦轨枕本地化生产 的空白,更以"中国方案"推动米轨铁路升级改造加快实施,助力提升坦桑尼亚铁路基础设施自主化和现 代化水平。 生产线涵盖张拉、蒸养、脱模等全流程关键工序,严格对标国际铁路工程标准,并通过高自动化控制系 统实现从原料配比到成品检测的精准管控,确保每一根轨枕均契合坦桑尼亚米轨铁路的运营特性,为铁 路长期安全、稳定运行夯实质量根基。 据悉,该轨枕厂是中国土木推动坦中央线米轨铁路由钢枕向预应力混凝土轨枕转型的重要举措。长期以 来,坦桑尼亚米轨铁路普遍使用钢制轨枕,且高度依赖进口,不仅采购成本高、运输周期长,还常常受 到国际供应链波动影响,难以保障铁路修复改造与日常养护的连续性,成为制约铁路发展的供应链瓶 颈。为打破这一困境,中国土木提出并实施轨枕转型的"中国方案 ...
