Leadcrete Equipment can supply you with high quality dry mix shotcrete machine for tunnel works, its ability to work in confined spaces and adapt to varying geological conditions makes it indispensable for enhancing safety, mitigating rockfall risks, and accelerating construction timelines in underground projects. By eliminating the need for traditional formwork and enabling continuous application, shotcrete machines significantly reduce labor and material costs while delivering superior durability and load-bearing capacity.

The LZ-5 series shotcrete machine is a typical example of this type of machine, with an output of 5m3/h and a horizontal conveying distance of up to 200m. They are capable of handling aggregates up to 15 mm in diameter, ensuring durability while maintaining a small footprint. For example, the electric version of the LZ-5E (5.5kW motor) strikes a balance between power and energy efficiency, making it an ideal choice for projects with limited diesel resources.



Designed to operate efficiently in narrow tunnels, these machines are equipped with adjustable nozzle angles and flexible hose lengths to easily reach challenging areas. They are equipped with a lightweight and sturdy frame to ensure ease of transportation and on-site installation. Key features include:
High-pressure concrete delivery (up to 6-8 MPa) ensures that concrete adheres firmly to irregular surfaces.
Dust suppression system minimizes environmental impact and improves operator safety.
Automated controls ensure consistent material mixing and application rates, reducing human error.
Accelerator (optional) speeds up concrete hardening, which is critical for time-critical projects.
Remote operation capabilities (advanced models) for hazardous environments.
Applications span joint filling, slope consolidation, and structural reinforcement in mines or tunnels. Their versatility extends to refractory lining in industrial kilns, demonstrating adaptability across sectors. By eliminating the need for formwork and enabling continuous application, these machines significantly reduce construction time and labor costs while enhancing safety through immediate stabilization of loose substrates.
