Carrying device of three advance geology forecasting instruments on TBM (Tunnel Boring Machine)

Abstract

The invention discloses a carrying device of three advance geology forecasting instruments on a TBM (Tunnel Boring Machine). The carrying device comprises a transmission supporting and shock absorption device, a telescopic transmission system and an instrument cabin protection device, wherein the transmission supporting and shock absorption device is convenient for carrying power supplying/measuring electrodes, and installing seismic wave vibration exciters and a seismic wave sensor on a TBM cutter disk; the telescopic transmission system is convenient for carrying an oblique single-hole geology radar transmitting and receiving antenna above a TBM rear support; the instrument cabin protection device plays a protection role when the TBM is in boring operation and is convenient for carrying an instrument cabin controlling the whole detection work at the inner part of the TBM rear support. According to the carrying device disclosed by the invention, the integration of detection instruments and the TBM is realized, the detection space and the detection time of a full-face excavation tunnel are fully utilized, the detection instruments are automatically and quickly distributed on a working surface of the TBM, an advance detection hole is drilled, the three advance geology forecasting instruments are successfully carried, the detection efficiency of advance geology forecasting and the automation and rapidity level are increased, and the advance geology forecasting capacity of the TBM is obviously enhanced.

Description

Technical field [0001] The invention relates to a carrying device on a full-face tunnel boring machine (TBM), and mainly relates to a special carrying device for three advanced geological forecast instruments on the TBM, belonging to the technical field of TBM. Background technique [0002] In recent years, tunnel boring machine construction methods are mostly used in tunnel construction in the United States, Japan, Norway, Switzerland and other countries with strong tunnels, and tunnel boring machine construction methods are increasingly used in tunnel construction in my country. Compared with traditional drilling and blasting construction projects, the roadheader construction method has many advantages of "fast construction speed, little excavation disturbance, safety and environmental protection", but the tunnel boring machine has poor adaptability to geological conditions. When TBM encounters bad geological conditions, geological disasters such as water bursts, landslides and...
