Recently, Guinea's first modern railway, the first aluminum ore train of Guinea Dasheng Railway, which was built by China Railway 14th, 18th, 21st Bureau and other units under CRCC, was successfully transported out, marking the countdown to the full opening of the railway. .

As the first modern railway in Guinea, West Africa in nearly half a century, the railway is the "economic artery" of Guinea. The total length of the railway is 112.29 kilometers and the design speed is 80 kilometers per hour. China Railway 14th Bureau Group is responsible for 36.3 kilometers of construction tasks and test and inspection services. The proportion of bridges and tunnels is 21.7%. Among all the bid sections of the whole line, the geology is the most complicated and the construction is the most difficult. The construction of the railway all adopted Chinese standards, Chinese technology, and Chinese equipment. This is the first time that China Railway Construction has entered the West African Guinea market, adding a touch of color to the Chinese railway's global expansion.

Faced with the tight schedule, the lack of materials and equipment, the complex terrain, the difficulty of concrete transportation, and the difficulty of construction in the rainy season, in order to successfully complete various construction and production tasks, the builders of China Railway 14th Bureau Group adopted the inverted schedule and implemented the responsibility contract system. In this way, we use the day and night operation mode to "grab the sunny day and fight the rainy day", which greatly improves the efficiency of construction production. In order to overcome the impact of the epidemic, the builders made overall planning, meticulous organization, unified resource allocation and personnel deployment, and formulated node goals with the overall idea of "guaranteeing excavation, fighting inverted arches, and grabbing secondary linings" to ensure safety and implementation. , The strong linkage "three-in-one" management mode promotes the construction of the project, the epidemic prevention construction is correct, and the maximum monthly excavation of a single entrance is 160 meters.

In recent years, China Railway 14th Bureau Group has implemented the "Overseas Priority" strategy, actively explored overseas markets, focused on overseas, supported overseas, participated in overseas, and continuously improved international business capabilities, continuously improved and strengthened, and the Guinea Dasheng railway project was successfully opened to traffic. It is a solid step taken by the company to become the best in the industry.

It is reported that after the completion of the Guinea Dasheng Railway, it will further strengthen Guinea's dominant position in the global bauxite market. The long-term prospects will be for third-party services, driving the further development of Guinea's domestic modern railway network, and even the entire West African railway network. , Thereby promoting the economic and social development of the entire African region.
