Transmission rod assembly, TBM-mounted advanced drill visualization device and application method thereof

Abstract

The invention belongs to the technical field of tunneling, and relates to a transmission rod assembly, a TBM-mounted advanced drill visualization device and an application method thereof. The device is characterized in that tunnel face advance surrounding rocks are drilled through a TBM-mounted advance drill; after drilling is completed, a probe and the transmission rod assembly is pushed into a TBM advanced drill hole through an advanced drill pushing system to conduct panoramic imaging, video recording, key part snapshot, drill hole track measurement and the like in the hole; and informationdetected by the probe is processed through an image editing processor in an imaging device host, and the processed result is displayed on a display, so that geological information such as hole wall cracks, cavities, water outlet positions of aquifers and fault structures in the full-length range of the TBM advanced drill hole is obtained. According to the device and the application method thereof, surrounding rock lithology, stratum fracture tectonic zones, geological disasters and the like in front of the tunnel face subjected to tunneling by a TBM can be qualitatively and quantitatively judged and interrupted, and a basis is provided for imaging accurate recognition.

Description

technical field [0001] The invention belongs to the technical field of tunneling, and relates to a transmission rod assembly, a TBM airborne advanced drilling visualization device and an application method thereof. Background technique [0002] With the continuous improvement of my country's national economic level, the quality and safety requirements of tunnel engineering are also increasing. More and more hard rock tunnels are constructed using the safer, more reliable and faster TBM construction method, and the TBM random supporting The role of advanced drilling rigs in the advanced geological exploration of tunnels is also becoming more and more important. However, the identification and analysis of advanced geological drilling results, surrounding rock lithology, geological disasters, etc. by the advanced drilling rig randomly matched with the existing TBM only stays at the level of the mechanical parameters of the drilling rig itself and the judgment of manual experienc...

AI Technical Summary

Problems solved by technology

However, the identification and analysis of advanced geological drilling results, surrounding rock lithology, geological hazards, etc. by the advanced drilling rig randomly matched with the existing TBM only stays at the level of the mechanical parameters of the drilling rig itself and the judgment of manual experience, and it is still impossible to achieve qualitative, Quantitative identification of surrounding rock lithology and geological hazards in front of the tunnel face with image recognition

In addition, the use of mechanized operation and detection methods is still in the blank, and the limitations of construction space and human cognition are becoming more and more prominent. The evaluation and judgment of traditional TBM advanced drilling experience can no longer meet the needs of hard rock tunnels, especially complex geological conditions. Requirements for rapid and precise mechanized construction of lower tunnels
