The LDJ400 The LDJ400 series multi-functional tunnel boring machine is an advanced and specialized equipment designed for non-explosive tunnel excavation. It primarily utilizes a high-frequency hammer or breaker hammer to fracture rocks, employing bucket teeth or drill rods to wedge into the surrounding rock. The gravity of the free face under the surrounding rock further assists in breaking through it. High-frequency hammers are ideal for rocks below 40MPa, while breaker hammers are used for harder rocks with poor development. This state-of-the-art machine boasts local control and wireless remote control capabilities, making it adaptable to tunnel excavations spanning 6 to 9.5 meters. Combining functionalities such as high-frequency rock breaking, swift soft soil excavation, contour trimming, and spray dust removal, it is perfectly suited for construction in blasting-restricted areas like airports, residential zones, and wildlife reserves. Exceptionally flexible, it meets the diverse construction requirements of various surrounding rocks, ensuring minimal over-excavation, under-excavation, and preventing landslides and other complications.
Achieves impressive excavation efficiencies of up to 50m³/h for grade IV and V surrounding rocks;Equipped with an efficient dust removal spray system, it effectively manages dust, ensuring a safer construction environment;Features a patented three-toothed or two-toothed base coupled with a high-frequency breaker hammer for rapid rock breaking and robust impact;
Minimal Disturbance to Surrounding Rock: Utilizes a non-explosive excavation method, significantly reducing the impact on surrounding rock;
Precise Over- and Under-Excavation Control: The machine's movements are precisely controlled, ensuring the contour surface's over- and under-excavation is kept within 20 centimeters;
Remote Control: All machine operations are remotely controlled for ease and convenience, allowing the operator to adjust positions flexibly for optimal operation;
Diesel-Electric Dual Power System: Supports diesel-powered emergency operations and electric construction, minimizing construction costs and preventing exhaust gas pollution in the tunnel. Heat accumulation is also significantly reduced during construction;
Efficient Slag Discharge: Select models come equipped with slag collecting and discharging devices, boasting a discharge capacity of 180m³/h. This meets the rapid slag discharge needs of small-section equipment, ensuring no site residue.
