Summary:
In modern tunnel construction projects, concrete wet-spraying rigs have become crucial equipment for enhancing the efficiency and quality of initial support. The ZXP4517 wet-spraying rig from Zhengxun Heavy Industry boasts outstanding advantages in various tunneling applications thanks to its comprehensive performance—efficiency, flexibility, and stability. This equipment not only demonstrates strong environmental adaptability but also enables continuous and precise operations even under complex geological conditions, providing robust support for the safe advancement and schedule control of tunnel projects.
The patented boom design offers wider coverage and enhanced operational stability. The ZXP4517 wet spray carriage is equipped with a patented boom system independently developed by Zhengxun Heavy Industry, which supports 360° horizontal rotation and large-angle pitch adjustment, enabling flexible coverage of critical areas such as tunnel arches, sidewalls, and curves. This design helps address the issue of uneven force distribution commonly found in traditional equipment, improving the smoothness and service life of the boom’s operation while reducing phenomena like spray leakage and over-spray, thereby enhancing the overall quality of spraying operations. 
For large-diameter conveying pipelines, smoother pumping and reduced failure rates are achieved. This equipment utilizes high-strength conveying pipelines with an inner diameter of no less than 125 mm. Compared to conventional pipelines, the larger diameter helps reduce concrete flow resistance, enhance pumping efficiency, and ensure continuous and uniform concrete spraying, thereby improving the compactness and strength of the initial support layer.
With efficient power and intelligent control, the ZXP4517 is designed to handle complex construction environments. Equipped with hydrostatic four-wheel drive and a hydraulically assisted steering system, coupled with engineered off-road tires, this machine delivers excellent passability and stability even when navigating slopes, curves, and uneven surfaces inside tunnels. The intelligent control system supports remote operation and parameter adjustment, simplifying the construction process, reducing operational complexity, and significantly enhancing tunneling accuracy and response speed.
From the precise coverage of tunnel vaults to the flexible adaptation to curved sidewalls, the ZXP4517 wet spray carriage from Zhengxun Heavy Industry consistently delivers stable performance, safeguarding engineering quality and serving as a core support for cost reduction, efficiency improvement, and safe advancement in tunnel construction.
