Real-time management of tunnel cross-section shape and ground evaluation during excavation.
This technology is a tunneling support system that enables real-time management of tunnel excavation shape and quantitative evaluation of ground conditions during excavation using a free-section excavator. In this system, the position and posture of the excavator are monitored using a high-speed 3D scanner installed on the machine, allowing for the real-time visualization of excavation position information (the position of the cutter tip) while simultaneously quantitatively evaluating the characteristics of the excavated ground based on the amount of electrical energy consumed during excavation. As a result, it becomes possible to grasp the tunnel excavation shape and the stability of the ground in real-time during excavation work, thereby improving the efficiency and safety of the excavation operations. 【Features】 ■ Measurement of machine position and posture using a high-speed 3D scanner ■ Improvement of excavation efficiency and safety ■ Three-dimensional quantitative evaluation of the excavated ground ■ Real-time monitoring from remote locations ■ Integration with CIM *For more details, please download the PDF or contact us.
