A transparent cover is provided at the front end of the pipe sleeve 7, and the rear end of the pipe sleeve 7 communicates with the front end of a conduit 9. An imager 2 and a transceiver integrated radial transducer 5 are fixedly installed in the pipe sleeve 7. The measuring end of the imager 2 is located inside the transparent cover. The imager 2 and the transceiver integrated radial transducer 5 are respectively connected to an ultrasonic analysis video display device 12 through a first line 3 and a second line 6 passing through the conduit 9. The device further includes a plurality of guiding assemblies. Each guiding assembly includes more than two telescopic sleeves 11. A guiding wheel 10 is installed at the movable end of the telescopic sleeve 11. An elastic member is arranged inside the telescopic sleeve 11. Two ends of the elastic member are respectively connected to the fixed end and the movable end of the telescopic sleeve 11. The guiding assemblies are distributed on the pipe sleeve 7 and the conduit 9. The telescopic sleeves 11 of the guiding assemblies located on the pipe sleeve 7 are evenly distributed along the circumferential direction of the pipe sleeve 7, and the fixed ends of the telescopic sleeves 11 are installed on the pipe sleeve 7. The telescopic sleeves 11 of the guiding assemblies located on the conduit 9 are evenly distributed along the circumferential direction of the conduit 9, and the fixed ends of the telescopic sleeves 11 are installed on the conduit 9.

[0022] The current methods for detecting the surrounding rock geology during the excavation of vertical shafts / inclined shafts are divided into advanced geological forecasting or on-site forecasting by the design geological engineer for each footage. There are certain problems with both of the above forecasting methods. The on-site forecasting by the geological engineer is carried out manually, with high labor intensity for personnel and potential safety hazards, so it is not often used. The working principle of advanced geological forecasting is to predict geological conditions by using the reflection wave characteristics generated by seismic waves in inhomogeneous geological bodies. The current problems are: limited forecasting distance and insufficient forecasting accuracy due to the influence of the actual geological conditions of vertical shafts / inclined shafts.

[0023] The improvement of the present utility model lies in: a pipe sleeve 7 and a transparent cover are provided, and the imager 2 for detection and the integrated transceiver radial transducer 5 are installed in the pipe sleeve 7. The imager 2 and the integrated transceiver radial transducer 5 are connected to the ultrasonic analysis video display device 12 through wires. The pipe sleeve 7 is inserted into the pilot hole by means of propulsion. Video information is collected by the imager 2, and the integrated transceiver radial transducer 5 emits and receives ultrasonic waves in real time to detect the surrounding rock conditions. The upper horizontal section and the lower horizontal section of the pressure pipeline are connected through the pilot hole. The ultrasonic analysis video display device 12 is placed at the upper horizontal section of the pressure pipeline. The collected video information and ultrasonic data are fed back to the ultrasonic analysis video display device 12 through wires, providing geological exploration data of the inclined shaft / vertical shaft surrounding rock for the next-step geological design engineers and construction personnel. The detection method of the present utility model is to insert the imager 2 for detection and the integrated transceiver radial transducer 5 into the pilot hole for detection, with high accuracy of the detection results and a longer detection distance under the geological conditions of the vertical shaft / inclined shaft. It also includes a plurality of guiding components installed on the outer sides of the pipe sleeve 7 and the conduit 9. The guiding components are composed of guiding wheels 10 and telescopic sleeves 11 with elastic members inside. They are arranged on the outer sides of the pipe sleeve 7 and the conduit 9 to support the pipe sleeve 7 and the conduit 9, and the telescopic sleeves 11 with elastic members inside adapt to the uneven inner wall of the pilot hole, reducing the sway when the present utility model advances, enabling the imager 2 and the integrated transceiver radial transducer 5 to be in a stable state for detection, and reducing the errors generated during the detection process. Moreover, it makes the present utility model convenient to retract and extend, facilitating the real-time collection and analysis of video and acoustic data.

[0024] As Figure 4 shown, further, it also includes a data line displacement measuring wheel 13. The first wire 3 and the second wire 6 are wound around the data line displacement measuring wheel 13 and then connected to the ultrasonic analysis video display device 12.

The data line displacement measuring wheel 13 records the descending depth through the displacement of the wires, providing data on the advancing depth of the present utility model.

[0025] Preferably, the transparent cover is a glass imager protection cover 1, and the glass imager protection cover 1 has a better imaging effect.

[0026] Preferably, the elastic member is a compression spring.

The fixing frame 4 is provided for installing the imager 2 and the integrated transceiver radial transducer 5 to ensure stability during use.

[0028] Further, two rubber sealing rings 8 are arranged inside the pipe sleeve 7. The rubber sealing rings 8 are respectively arranged at both ends of the transceiver integrated radial transducer 5 to enclose the space where the transceiver integrated radial transducer 5 and the imager 2 are located, so as to prevent the dust at the rear end of the catheter 9 from affecting the working imager 2 and the transceiver integrated radial transducer 5.
