Xiongxin High-speed Railway as an important transport link, China Railway 12th Bureau and Liming Group join hands to build a high-quality sand and gravel aggregate project in Shanxi section, which makes full use of the raw materials of cave dregs and adopts advanced processing technology to meet the demand of high-speed railway construction. The project focuses on environmental protection and process design to ensure stable operation of the production line and improve production efficiency. The co-operation between the two sides once again proves the professional strength and helps the national infrastructure construction.

The Xiongxin high-speed railway, as an important transport link connecting Xiongan and Xinzhou, is not only a key link of the Beijing-Kunming corridor in the national "eight longitudinal and eight transverse" high-speed railway network planning, but also a new engine for regional economic development. China Railway 12th Bureau and Liming Group join hands again to build a high-quality sand and gravel aggregate project in Shanxi, which is another successful cooperation model after the Yukun railway project.

1. Source of raw materials and processing technology

Located in Wutai County, Shanxi Province, the project makes full use of the cave slag produced during the railway construction as raw materials. Through the advanced feeder, jaw crusher, single-cylinder hydraulic cone crusher, impact crusher and vibrating screen and other equipments, the cave dregs are processed into high-quality sand and gravel aggregate with different specifications, such as 0-5-10-20-32.5mm, which ensures the demand of materials for high-speed railway construction.

2. Environmental protection and process design

Facing the complex terrain of North Taihang Mountain and the environmental protection requirements of Wutai Mountain and other cultural protection areas, the project team carefully designed the wet production line that meets the local terrain and environmental protection requirements through several on-site surveys. This not only ensures the stable operation of the production line, but also improves the production efficiency while protecting the environment.

3. Project Management and Implementation

In order to ensure that the project is completed on schedule, the project manager is personally stationed at the site, coordinates the deployment of resources, and rationally deploys the construction programme. In the face of heavy construction tasks, cross-construction and other unfavourable factors, all construction personnel rose to the challenge and worked strictly according to the construction plan to ensure the quality and progress of the project.

Project significance

The construction of Xiongxin High-speed Railway is of great significance to improve China's railway transport network and promote regional economic development. The successful implementation of this high-quality sand and gravel aggregate project not only provides strong support for the construction of the Shanxi section of the Xiongxin High-speed Railway, but also promotes the vigorous development of railway construction in Shanxi and contributes an important force to the national infrastructure construction.

The cooperation between China Railway 12th Bureau and Liming Group has once again proved the professional strength and service capability of both parties in the field of high-speed railway construction. In the future, both parties will continue to work together to provide high-quality sand and gravel aggregates for more high-speed railway projects, and jointly help the national infrastructure construction to create a better future.
