Summary:
In tunnel and underground engineering support construction, the pumping efficiency, stability, and reliability of the wet-mix shotcrete process are critical determinants of project schedule, construction costs, and support quality. Zhengxun Heavy Industry’s wet-mix shotcrete boom system takes the pumping system as the central focus of technological optimization and, through comprehensive, systematic upgrades across the entire workflow, effectively addresses longstanding industry challenges such as frequent pipe blockages, high material consumption, and cumbersome maintenance, thereby delivering an efficient, stable, and cost-effective wet-mix shotcrete solution for construction projects.
To address the industry challenges associated with traditional wet-spray equipment—namely, frequent hose blockages and high consumable losses—Zhengxun Heavy Industry’s wet-spray trailer is equipped with a dedicated rigid-pipe conveying system that replaces conventional flexible hoses with wear-resistant steel pipes. This design significantly reduces pumping resistance, fundamentally minimizing the risk of blockages and enabling each unit to achieve substantial annual savings in consumable costs. Moreover, the use of an advanced wear-resistant material for the rigid pipes markedly lowers the likelihood of blockages, ensuring stable, continuous operation. In addition, the equipment delivers guaranteed performance for large-volume concrete delivery and boasts dramatically enhanced durability, thereby reducing pipeline maintenance and energy consumption costs for users while providing a robust foundation for efficient pumping. 
To further ensure smooth pumping operations, Zhengxun Heavy Industry’s wet-spray rig is equipped with a dedicated desert-filter cartridge filtration system that efficiently performs primary filtration of large sand and gravel particles as well as other impurities, significantly enhancing filtration efficiency. Featuring a multi-stage design, this system markedly improves airflow smoothness and reduces power fluctuations. In addition, the inclusion of a transparent dust-collection cup enables visual monitoring and easy cleaning, thereby minimizing on-site maintenance time. By preventing impurities from entering the pumping system at the source, it effectively mitigates the risks of pipeline wear and blockage, adding an extra layer of protection for stable pumping performance. 
For high-intensity, continuous construction operations, Zhengxun Heavy Industry’s wet-spray boom truck is equipped with large-capacity quick-setting-agent and water tanks, significantly enhancing the storage and supply capacity of the quick-setting agent, reducing the frequency of replenishment, and markedly improving construction continuity and operational efficiency. The equipment also eliminates the need for frequent water refills, further bolstering operational consistency and effectively meeting the demands of large-scale, high-intensity projects by minimizing work interruptions caused by consumable resupply and ensuring the uninterrupted progression of pumping operations. 
Zhengxun Heavy Industry’s wet-spraying carriage centers on enhancing pumping efficiency, delivering multidimensional breakthroughs in operational productivity, maintenance costs, and construction stability. It provides an efficient, cost-effective, and reliable solution for wet-spraying operations in tunneling and underground engineering, making it a trusted, professional piece of equipment for structural support construction.
