[0030] In summary:

[0031] 1. A ground-penetrating radar 24 is installed on one side of the rotary tunneling head 22, and a laser scanner 14 is installed on one side of the support body 6. This enables the drive motor 20 to power the rotary tunneling head 22 for breaking and excavating the rock ahead. During the excavation process, the detection system operates continuously, monitoring changes in geological conditions in real time. The ground-penetrating radar 24 continuously detects information such as the degree of rock breakage and water content ahead, while the laser scanner 14 acquires real-time three-dimensional topographic data of the tunnel face. This data is transmitted to the control system in real time, and the central processing unit 16 adjusts the excavation parameters, such as the rotation speed of the drive motor 20 and the advance speed of the tunneling head, based on the changes in the data, thus ensuring the support effect.

A right-side support plate 8 and a left-side support plate 10 are respectively installed on one side of the first telescopic rod 7 and the second telescopic rod 9. A front support plate 12 is installed at the front end of the support body 6. A pressure sensor 13 is installed on one side of the front support plate 12. When the pressure sensor 13 detects pressure changes between the right-side support plate 8 and the left-side support plate 10 and the surrounding rock, it feeds the pressure data back to the control system. The central processing unit 16 judges the stability of the surrounding rock based on the pressure data and adjusts the extension and retraction of the second telescopic rod 9, the first telescopic rod 7, and the third telescopic rod 11 through the hydraulic system, thereby changing the contact pressure between the support plate and the surrounding rock and the support position.
