Summary:
In modern tunnel construction, initial support is a critical stage for ensuring construction safety and structural stability. As the core equipment for this stage, concrete wet spray rigs—thanks to their efficient, environmentally friendly, and precise operational capabilities—have become essential equipment widely used in various tunnel projects.
1. Wet spraying is highly efficient and provides comprehensive coverage.
The wet spray carriage is specially designed for tunnel applications. It uses a high-pressure pumping system to deliver pre-mixed wet concrete to the nozzle, where it is rapidly sprayed onto the excavation face after being mixed with a rapid-setting admixture. This process quickly forms a dense, uniform, and high-strength concrete layer. The ZXP4017/4517/5517 concrete wet spray carriages launched by Zhengxun Heavy Industry are exemplary products that integrate advanced hydraulic technology with intelligent control concepts. They not only significantly enhance construction efficiency but also fully meet the stringent requirements for high-quality support under complex geological conditions.
II. Arm frame stability, precise operation
The reason why the ZXP4517 wet spray carriage can operate continuously and stably in harsh environments lies in its multiple innovative designs. The entire machine is equipped with a highly flexible boom system that supports 360° horizontal rotation and large-angle pitching and swinging motions, ensuring precise and thorough spraying. By adopting a patented boom structure independently developed by Zhengxun Heavy Industry, the equipment effectively avoids uneven stress distribution, enhancing overall stability and extending service life. Key components, such as the slewing bearing, feature a large-diameter internal gear design for more reliable engagement. Additionally, the reducer is positioned above, optimizing maintenance space and facilitating daily upkeep.
3. Powerful performance, reliable operation
To enhance conveying efficiency, the entire machine uses high-strength conveying pipelines with an internal diameter throughout the entire system, significantly reducing pumping resistance and ensuring smooth concrete flow and uniform spraying. The chassis features hydrostatic four-wheel drive and a hydraulically assisted steering system, paired with heavy-duty off-road tires and a composite braking system, enabling flexible maneuverability and stable operation even in tunnels with steep slopes and rough road surfaces.
As a representative of domestically produced high-end wet spraying equipment, the ZXP4517 concrete wet-spraying carriage from Zhengxun Heavy Industry not only showcases the company’s professional expertise in the field of construction machinery but also drives tunnel construction toward greater mechanization, intelligence, and sustainability through its proven performance. In the future, as infrastructure development continues to raise demands for safety and efficiency, such high-performance wet-spraying equipment will play a critical role in an increasing number of key tunnel projects, providing solid support for the construction of major national projects.
