The invention provides an auxiliary signal acquisition device and system for seismic wave advanced detection of a double-shield TBM. The device comprises a duct piece and a conduction rod, the duct piece is provided with a pouring hole, one end of the conduction rod is directly attached to surrounding rock through the pouring hole, and the other end of the conduction rod exceeds the inner wall ofthe duct piece to the outer side. According to the technical scheme, the auxiliary signal device suitable for seismic wave advanced detection of a double-shield TBM not only needs to fully utilize anexisting segment structure of a double-shield TBM, but also needs to be easy and convenient to operate and not to affect the construction progress of the TBM. 本公开提出了用于双护盾TBM地震波超前探测的辅助信号采集装置及系统，包括：管片及传导杆，所述管片上开设有灌注孔，所述传导杆一端通过灌注孔与围岩直接贴合，另一端超出管片内壁至外侧。本公开技术方案适用于双护盾TBM地震波超前探测的辅助信号装置，既要充分利用双护盾TBM现有管片结构，还要操作简便，不影响TBM施工进度。
