The GZC-15/D Conveyor and Shotcrete Machine Combination is a core piece of equipment for concrete support/lining in tunnel, mine, and slope engineering projects. Its mobility, continuous operation capability, and high-pressure spraying effect perfectly match the needs of efficient, continuous, and mobile concrete work scenarios.
1. Tunnel Engineering:
Including railway tunnels, highway tunnels, subway tunnels, and water conservancy tunnels, requiring initial support (temporary support) and secondary lining (permanent lining) to prevent surrounding rock collapse and leakage, ensuring tunnel safety.
Core Requirements:
Frequent movement of the tunnel face (working face) necessitates rapid equipment relocation; Continuous spraying of the lining is required (avoiding joints) to improve construction efficiency; The concrete must be dense and non-porous (preventing leakage) to ensure the seepage prevention effect of the secondary lining; Reduced manual material feeding reduces labor intensity.
2. Mine Support:
This includes roadway support in coal mines, metal mines (iron mines, copper mines), and non-metal mines (limestone mines). It requires reinforcement of the surrounding rock to prevent collapses and roof falls, ensuring mine production safety.
Core Requirements:
Mine roadways are mostly composed of soft rock and fractured zones with poor surrounding rock stability, requiring rapid support; Concrete is often wet (15%-20% water content), easily clogging hoppers; Mine environments are mostly open-pit or underground (without power supply), requiring independent equipment operation.
3. Slope Reinforcement:
This includes slopes for highways, railways, hydraulic dams, and open-pit mines. It requires shotcrete reinforcement of the slope surface to prevent landslides and soil erosion, ensuring slope stability.
Core Requirements:
Slopes: Most slopes are steep (1:0.5-1:1.5), requiring concrete to be sprayed to higher elevations;
Large-area continuous work required (slope area can reach thousands to tens of thousands of square meters);
Mobilization of equipment to different locations on the slope (top, middle, bottom).
4. Underground Engineering:
Includes underground parking garages, subway stations, underground shopping malls, underground utility tunnels, etc., requiring support or lining of the foundation pit, side walls, and roof slab to prevent collapse and ensure the safety of the underground space.
Core Requirements:
Underground engineering spaces are limited (e.g., underground parking garages have a floor height of only 3-4 meters), requiring compact equipment;
Rapid support is required (to avoid prolonged exposure of the foundation pit and prevent collapse);
Dense and leak-proof concrete is required (waterproofing is crucial in underground engineering; leakage in the side walls of underground parking garages can lead to steel corrosion).
5. Emergency Repair:
Includes post-earthquake building reinforcement, landslide slope repair, and tunnel repair after collapse, requiring rapid on-site arrival for emergency support or lining to prevent secondary disasters.
Core Requirements:
Rapid relocation is necessary (disaster areas often experience traffic disruptions, requiring equipment to be transported to the site by road or helicopter); No reliance on power supply is required (power outages are common in disaster areas, necessitating independent operation of the equipment); Large-capacity material feeding is required (for rapid repair, such as slope repair which needs to be completed within 1-2 days); High-pressure jetting is needed (for rapid reinforcement of damaged areas to prevent further collapse).
