The LDJ400 series multi-functional tunnel boring machine stands as a cutting-edge solution for non-explosive tunnel excavation. This innovative machine employs a high-frequency hammer or breaker hammer to efficiently fracture rocks. Utilizing bucket teeth or drill rods, it strategically wedges into the surrounding rock, leveraging the natural gravity of the free face for effortless breakthrough. With high-frequency hammers ideal for rocks below 40MPa, and breaker hammers for harder, less developed rocks, this equipment excels in diverse conditions. It boasts a combination of local control and wireless remote control, adaptable for tunnel diameters ranging from 6 to 9.5 meters. It offers multifaceted capabilities including high-frequency rock breaking, swift soft soil excavation, precise contour trimming, and spray dust removal, making it perfect for construction in restricted blasting zones such as airports, residential areas, and wildlife reserves. Its exceptional flexibility accommodates various rock formations, minimizing over- and under-excavation, and preventing landslides and other complications.
Achieves comprehensive excavation efficiency for grade IV and V surrounding rocks, reaching up to 50m³/h;
Equipped with a comprehensive dust removal spray system, effectively managing dust to ensure a safe construction environment;
Features a patented three-toothed or two-toothed base paired with a high-frequency breaker hammer, delivering rapid rock breaking with powerful impact;
Minimal Disturbance to Surrounding Rock: Employs a non-explosive excavation method, causing negligible disturbance to the surrounding rock;
Accurate Over- and Under-Excavation Control: Precisely controls the entire machine's movements, with contour surface over- and under-excavation accuracy within 20 centimeters;
Remote Control: Facilitates complete machine operation remotely, providing easy and convenient control. Operators can adjust the position flexibly for enhanced operational convenience;
Diesel-Electric Dual Power System: Supports diesel-powered emergency and transmission operations, alongside electric construction, reducing costs significantly. This system prevents exhaust gas pollution in the tunnel and keeps heat accumulation minimal during construction;
Efficient Slag Discharge: Certain models include slag collecting and discharging devices, with a discharge capacity of 180m³/h, catering to small-section equipment needs for rapid slag removal without site departure.
