Jining Tongzhao Machinery Co., Ltd. is one of the most reliable manufacturers and suppliers of tunnel excavation in China. If you're going to wholesale durable tunnel excavation made in China, welcome to get pricelist from our factory. All customized products are with high quality and competitive price.
Core product advantages 1. Efficient and energy-saving, construction speed: Equipped with an upgraded hydraulic control system, the power output is stable, reducing energy consumption by about 15% compared to traditional equipment. The drilling speed is fast and the hole formation is regular. Single arm, double arm, and three arm models can operate synchronously at multiple stations, greatly shortening the tunnel excavation and support construction cycle and adapting to large-scale engineering construction. 2. Accurate and stable, suitable for complex geological formations: Supports fully automatic positioning drilling, computer intelligent control, high drilling accuracy, can accurately complete forward and side wall fan-shaped drilling, effectively solving the problem of collapse holes in soft soil layers and fractured rock layers, with a high pass rate of drilling, ensuring the quality of subsequent support and grouting construction. 3. Strong adaptability to working conditions: divided into track type and wheel type walking structures, the body is compact and flexible, and can adapt to low and narrow working spaces in tunnels; The equipment has strong protection, dust-proof, explosion-proof, and anti vibration characteristics, and can cope with underground construction environments that are humid, dusty, and complex geological conditions. 4. Multi functional integration, one machine for multiple purposes: It can switch multiple drilling processes, taking into account various drilling operations such as blasting holes, anchor holes, grouting holes, drainage holes, geological core holes, etc. At the same time, it supports supporting operations such as tunnel advance geological prediction, surrounding rock reinforcement, and pipe shed construction without the need for equipment replacement, reducing construction costs. 5. Safe, convenient, and easy to maintain: Intelligent remote control reduces the risk of personnel working at high altitudes and rock walls in close proximity; Modular design of equipment structure, easy disassembly and assembly, low failure rate, simple on-site maintenance, suitable for long-term continuous construction. Main model parameters and characteristics: conventional construction aperture of 45-64mm, maximum drilling depth of up to 6m or more; The intelligent model supports automatic drilling and precise positioning, and the multi arm model can synchronize multi station operations, fully adapting to the construction needs of large and small tunnels and underground engineering.
