Under the blueprint of the national comprehensive three-dimensional transportation network, the Shijiazhuang section of Hengxi Expressway, a key transportation infrastructure project in Hebei Province during the 14th Five-Year Plan, is being rapidly promoted. This project not only connects cities and villages, but also injects new vitality into regional economic development. Against this background, Shijiazhuang Jiaotong Group faced the challenge of gravel aggregate supply. However, they successfully coped with this problem through an innovative production line.

Introduction to gravel aggregate equipment for highways

Project background

As the construction party of the Shijiazhuang section of Hengxi Expressway, Shijiazhuang Jiaotong Group needs to open a 9-kilometer high-speed tunnel. In order to achieve the goals of green environmental protection and cost reduction and efficiency improvement, the project decided to carry out deep processing of the basalt cave slag produced by tunnel blasting to support engineering construction.

Challenges and solutions

The project team faced multiple challenges: tight construction period, limited work site, and large volume and high hardness of basalt cave slag. After in-depth analysis, they chose the MK agglomerate crushing and screening station solution of Shibang Group.

This solution is equipped with three MK series crushing and screening stations - jaw crusher, cone crusher and screening station, and adopts a "C" shaped layout. In the finished product transportation link, the discharge port is designed to be directly connected to the belt conveyor, which solves the problem of narrow site, reduces the transit transportation cost, and truly achieves energy conservation and emission reduction.

Effects and Results

Another advantage of the MK crushing and screening station is its foundation-free installation design. It can be put into use quickly by simply compacting and leveling the site, which greatly shortens the project construction cycle and reduces the initial investment. In addition, in order to deal with the dust problem in the production process, the equipment is also equipped with a spray device, which effectively achieves the expected environmental protection goals.

Through this series of measures, Shijiazhuang Jiaotong Group successfully guaranteed the construction progress of the Hengxi Expressway project, achieved the dual benefits of environmental protection and economy, and added a strong touch to Hebei Province's "14th Five-Year Plan" transportation blueprint.

Conclusion

This case shows how to overcome challenges and promote the smooth progress of projects through innovative production solutions in infrastructure construction. With its high efficiency and environmental protection characteristics, the MK block crushing and screening station provides strong support for future infrastructure construction.
