Description

Technical Field

[0001] This utility model relates to the field of TBM tunnel technology, and in particular to a TBM tunnel advanced geological prediction system. Background Technology

[0002] In existing technologies, the proportion of full-face tunnel boring machines (TBMs) used in tunnel construction is increasing. TBMs are a new type of advanced tunnel construction machinery that uses rotating cutters to excavate, simultaneously break up the surrounding rock, and excavate to form the entire tunnel cross-section. A significant problem with TBMs is their poor adaptability to changing geological conditions. When encountering faults, fracture zones, lithological interfaces, water-bearing structures, or other adverse geological conditions, serious accidents such as TBMs getting stuck, buried, or even rendered unusable often occur. To reduce the risk of such accidents during TBM construction, the most effective solution is to use advanced geological forecasting technology to identify adverse geological conditions ahead of the tunnel face in advance and to develop reasonable contingency plans and treatment measures based on these conditions.

[0003] Currently, there are two main methods for geological advance prediction technology in TBM tunnel construction: ① One method is to use the advance drilling rig equipped with the TBM for horizontal drilling. This type of drilling rig can only reveal the geological conditions around the borehole, and cannot detect geological bodies that do not intersect with the borehole. It cannot reflect the geological conditions of the entire area in front of the TBM working face, and is prone to missing unfavorable geological conditions, resulting in false alarms, misreporting, and potential disaster risks. Moreover, the economic and time costs of drilling are relatively high. ② The other method is to use the BEAM (Bore-Tunneling Electrical Ahead Monitoring) system developed in Germany. BEAM is a one-dimensional focusing excitation polarization method. The disadvantages of the BEAM method are: firstly, the testing equipment is complex to install and the testing time is long, which seriously affects the construction progress; secondly, the BEAM method uses the curve of each measurement result and the tunnel mileage to infer the water content in front of the tunnel face. The detection distance is small, and it does not use tomographic imaging detection, so it cannot obtain three-dimensional information of the geological bodies in front of the TBM working face, nor can it predict the water volume. Due to the limited detection space, severe electromagnetic interference, and short available time in TBM construction tunnels, there are currently no highly effective and practical advanced geological prediction technologies and devices.

[0004] Chinese utility model patent application number 201420009498.3 discloses a forward cross-hole radar transmission imaging advanced prediction system for TBM construction tunnels. It includes a mechanical telescopic spiral device installed inside the TBM body and behind the TBM cutterhead, composed of multi-stage telescopic elements. The front end of the mechanical telescopic spiral device is detachably connected to a drill bit or an expandable multi-stage tandem radar antenna fixing sleeve. Under the control of the mechanical telescopic spiral device controller, two holes of equal depth are drilled in the surrounding rock in front of the TBM body, and the sleeve is installed. A radar transmitting antenna and a radar receiving antenna are then arranged in the two holes respectively. The radar transmitting antenna and the radar receiving antenna are connected to a multi-channel radar host and a computer. However, this forward cross-hole radar transmission imaging advanced prediction system for TBM construction tunnels requires pre-setting multiple measuring points for geological prediction, and redeploying the radar antennas when detecting radar data at each pre-set measuring point. The operation is cumbersome, the system deployment cycle is long, and it cannot achieve rapid detection of tunnel geology, affecting the construction progress. Utility Model Content

[0037] Working principle:

[0038] Before using a full-face tunnel boring machine for mechanical construction, measuring points are selected at the tunnel face. Geological samples are taken from these points using sampling drilling equipment to obtain soil columns. Based on the specifications of the soil columns, the spacing between two sets of rubber roller assemblies is adjusted using an adjusting component. The soil columns are then placed above the two sets of rubber roller assemblies. Subsequently, the electronic control unit 24 controls the limiting telescopic rod 11 to lower the limiting block 12 and the limiting top plate 13 to limit the soil columns. Then, the electronic control unit 24 controls the detection cylinder 16 and the lifting cylinder 21 to adjust the position of the detection radar 19, moving it to the end of the soil column. Finally, the electronic control unit 24 controls the detection radar 19 to continuously detect the soil columns and record the detection results. This allows for the analysis and prediction of the geology ahead of the tunnel face. The analysis and prediction method can adopt existing geological analysis methods. During the detection process, the soil columns can be rotated by a certain angle via the supporting rubber roller 8 under the action of the rubber roller motor to adjust the detection angle of the soil columns.

[0039] The beneficial effects of this utility model are that it is equipped with a support mechanism and a limiting mechanism, which can provide rotational support for the geological soil column collected by the preset measuring point and divide it into depths. Then, the geological conditions at different depths of the geological soil column can be continuously detected by the detection mechanism. The geological conditions of the target area can be predicted by the detection data. The continuous detection of the geological soil column collected by a single measuring point can quickly and accurately predict the geological conditions in front of the tunnel excavation face. The operation is simple, the system deployment cycle is short, and the construction progress is accelerated.
