The LDJ400 series of multi-functional tunnel boring machines is a state-of-the-art solution for non-explosive tunnel excavation. Utilizing a high-frequency hammer or breaker hammer, these machines efficiently break rocks. The mechanism involves using bucket teeth or drill rods to wedge rocks, leveraging the gravity of the surrounding rock to create an automatic breakthrough. High-frequency hammers are ideal for rocks below 40MPa, while breaker hammers are perfect for harder rocks. Controlled both locally and remotely, this equipment adapts to tunnels ranging from 6 to 9.5 meters. It excels in high-frequency rock breaking, swift soft soil excavation, contour trimming, and spray dust removal, making it an excellent choice for construction in blasting-restricted zones like airports, residential areas, and wildlife reserves. This versatile machine is engineered to handle various rock types, minimize over- and under-excavation, and prevent landslides and other complications.
Excavation Efficiency: Achieve a comprehensive excavation efficiency of up to 50m³/h for grade IV and V surrounding rocks.
Minimal Disturbance to Surrounding Rock: The non-explosive excavation method ensures minimal disturbance to the surrounding rock.
Precise Excavation Control: Accurately controlled machine movements allow for over- and under-excavation control within 20 centimeters.
Spray Dust Removal: Equipped with a dust removal spray system to effectively manage dust, ensuring a safe construction environment.
High-Frequency Rock Breaking: Features a patented three-toothed or two-toothed base and a high-frequency breaker hammer for rapid rock breaking and strong impact.
Remote Control: All machine movements are controlled remotely, offering ease of operation and flexibility in positioning.
Diesel-Electric Dual Power System: Supports both diesel-powered emergency operations and electric construction to minimize costs and prevent exhaust gas pollution in tunnels, while also controlling heat accumulation.
Efficient Slag Discharge: Some models come with slag collecting and discharging devices, boasting a capacity of 180m³/h, ideal for rapid slag removal in small-section equipment without site departure.
