Abstract

The invention discloses a tunnel boring machine airborne resistivity advanced detection real-time collection electrode system and method. The system comprises a variable direction electrode mechanism, an elastic expansion device and a variable resistance positioning mechanism. The variable direction electrode mechanism comprises a contact electrode piece and a variable direction transmission piece. The contact electrode piece is freely rotated around a center axis through the variable direction transmission piece, and sliding friction in contact with a rock surface is converted into rolling friction. The retraction and ejection of an electrode are ensured by the elastic expansion device. The variable resistance positioning mechanism comprises a sliding rheostat, the positioning is carried out with a polar coordinate system as a coordinate axis, and with the center of a cutter as the center of the polar coordinate system, through detecting the change of the resistance value of the sliding rheostat, different positions of the cutter are determined so as to calculate and track the position of the electrode. According to the system and the method, the detection in a cutter boring process can be effectively realized.

Description

technical field [0001] The invention relates to an electrode system and method for advanced detection and real-time acquisition of an airborne resistivity method of a tunnel boring machine. Background technique [0002] The rapid development of my country's economy and society in the 21st century has promoted the rapid development of science and technology. In recent years, tunnel engineering construction has achieved fruitful results. Among them, tunnel boring machine, as a kind of tunnel construction and excavation equipment with many advantages such as fast excavation speed, high construction safety, small surface disturbance, low labor cost and high degree of mechanical automation, is widely used in the construction of major tunnels at home and abroad. Greatly improved the mechanization and automation level of tunnel construction. [0003] However, due to the uncertainty of the geological body ahead of the excavation, during the forward excavation process of the tunnel...
