Compared with traditional drilling and blasting methods, TBM has a “mechanized automation degree”. It has significant advantages such as high speed, fast excavation speed, high quality of hole formation, small construction disturbance, high comprehensive economic and social benefits, safety, civilization and environmental protection. However, the TBM construction method has poor adaptability to geological conditions. In the TBM construction, disasters such as water inrush and mud inrush, landslides, and large deformations are often encountered, resulting in major accidents such as jamming, damage, scrapping, and even casualties of the roadheader. It is extremely important to implement advanced geological forecasting during TBM construction.

在TBM开始掘进且切削下来的岩渣被TBM主传送带1传送到该装置的下方后，在TBM主控室按下整个***的工作按钮，该装置开始工作。首先是机械轮机构5开始工作，液压泵和液压控制阀控制液压立柱11收缩，从而控制机械轮下降至合理高度。随后机械轮5中的伺服电机12开始工作，转轮13开始逆时针缓慢转动，当转动到最下方时，斗舱17将会挖取到TBM主传送带上的岩块，此时，在转轮缓慢转动过程中液压杆16伸长直至斗舱中岩块与上方的楔形座18相接触时停止。随后液压立柱会伸长从而控制机械轮上升，此时冲洗机构4会开始工作，喷出高压水流对斗舱17与楔形座18之间夹有的岩块进行清洗。随着机械轮机构上的斗舱转动到传送机构6上方合适位置时，液压杆的收缩会使斗舱中的岩块掉落到传送机构6上。当岩块运移到烘干机构7的正下方时，传送机构6停止工作，控制装置10开始控制风干装置7进行工作，吹出热风，在2分钟后，待测岩块的表面即被烘干，烘干机停止工作。随后传送机构6再次开始工作，将待测岩块传送到打印机构8的下方，传送机构6再次停止工作，打印机构8开始工作，将从TBM主控室微机中获取到的掌子面里程信息打印到下方的岩块上。随后传送机构6继续工作，将待测岩块传送到后方的装样箱9中，一次取样工作即完成。After the TBM starts to dig and the cut slag is conveyed to the bottom of the device by the TBM main conveyor 1, press the working button of the entire system in the TBM main control room, and the device starts to work. First, the mechanical wheel mechanism 5 starts to work, and the hydraulic pump and hydraulic control valve control the hydraulic column 11 to contract, thereby controlling the mechanical wheel to descend to a reasonable height. Then the servo motor 12 in the mechanical wheel 5 starts to work, and the runner 13 starts to slowly rotate counterclockwise. When it rotates to the bottom, the bucket 17 will dig up the rock block on the TBM main conveyor belt. During the slow rotation, the hydraulic rod 16 extends until the rock block in the bucket comes into contact with the wedge seat 18 above it and stops. Subsequently, the hydraulic column will extend to control the mechanical wheel to rise. At this time, the washing mechanism 4 will start to work, spraying high-pressure water to clean the rock blocks sandwiched between the bucket 17 and the wedge seat 18. As the bucket on the mechanical wheel mechanism rotates to a proper position above the transfer mechanism 6, the contraction of the hydraulic rod will cause the rock in the bucket to fall onto the transfer mechanism 6. When the rock block is moved directly below the drying mechanism 7, the conveying mechanism 6 stops working, and the control device 10 starts to control the air drying device 7 to work and blow out hot air. After 2 minutes, the surface of the rock block to be tested is dried , The dryer stops working. Then the transfer mechanism 6 starts to work again to transfer the rock mass to be tested to the bottom of the printing mechanism 8. The transfer mechanism 6 stops working again, and the printing mechanism 8 starts to work. The palm surface mileage information obtained from the microcomputer in the TBM main control room Print on the rock block below. Then the transfer mechanism 6 continues to work and transfers the rock block to be tested to the sample loading box 9 at the rear, and one sampling is completed.
