Abstract

The invention relates to the field of tunnel construction, and discloses a tunnel geological exploring method and system and a mini-type heading machine. The positions of at least two exploring holes are determined on a tunnel face of a tunnel; the mini-type heading machine is placed in the exploring holes, a tunneling path and a positioning program are input through a computer in a control chamber of a shield tunneling machine, the mini-type heading machine is started, and a rock mass is broken; and when a bad stratum is encountered or rock mass parameters need to be measured, the geological condition of the rock mass is measured; and measuring data are sent to the computer in the control chamber of the shield tunneling machine, and accordingly the analysis is conducted. The running performance of the tunnel geological exploring method and system and the mini-type heading machine is stable, the interference resisting capability of data transmission is high , surrounding rock information parameters can be accurately obtained, the tunnel geological exploring method and system and the mini-type heading machine can be combined with the shield tunneling machine, and the advanced prediction of the real-time geological condition is achieved.

Description

technical field [0001] The invention relates to the field of tunnel construction, in particular to a tunnel geological exploration method, system and miniature boring machine. Background technique [0002] At present, the commonly used technical methods for advanced geological prediction in tunnel engineering construction are advanced drilling exploration and geophysical advanced geological prediction. The occurrence of landslide accidents. Therefore, in order to accurately detect the unfavorable geological conditions in front of the tunnel and ensure the safety of tunnel construction, a device that can continuously explore the geological conditions in front of the tunnel face and transmit the geological condition information in time is needed. [0003] Some technical solutions have been proposed in the prior art, for example: Patent 1: CN103603669A discloses a shield tunnel bad geological forecasting device, the forecasting device includes: a radar system, the radar system...
