Abstract

The invention provides a system and a method for advanced geological prediction of TBM-carried radioactive radon. The radon concentration testing module mounted on the TBM comprises an air radon concentration testing unit and a water radon testing unit; the air radon concentration testing unit comprises an air collecting bag and a first drying pipe which are connected in sequence, a filter membrane is arranged between the air collecting bag and the first drying pipe, an aspirator pump is arranged at one end of the first drying pipe, and the other end of the first drying pipe is communicated toa continuous radon measuring instrument through a pipeline; the water radon testing unit comprises a diffusion bottle; a water taking device is arranged in the diffusion bottle, the diffusion bottleis connected with one end of a second drying pipe, and the other end of the second drying pipe is connected to the continuous radon measuring instrument through a pipeline; the continuous radon measuring instrument measures the radon content in air and water, transmits the radon content to the data processing and analyzing module so as to analyze and calculate the radon concentration, thus monitoring the radon concentration in the TBM tunnel for a long time, and providing a radon concentration curve graph and an abnormal lower limit in real time.

Description

technical field [0001] The disclosure belongs to the field of advanced detection and prediction of tunnels, and in particular relates to a system and method for advanced geological prediction of TBM-mounted radioactive radon. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] The internationally recognized tunnel boring machine construction method has the advantages of "fast excavation speed, small construction disturbance, and high comprehensive economic benefits". When the construction of TBM tunnels encounters bad fault geology, it is very likely to induce serious geological disasters such as jamming, water inrush and landslides under construction disturbances. Therefore, in the process of TBM tunnel construction, it is necessary to accurately predict the occurrence of adverse geological conditions. [0004] The existing advanced geolog...
