#$%^&*AU2020102355A420201029.pdf#####ABSTRACT The present invention discloses an embedded microseismic monitoring device with a TBM, including a supporting shoe arranged on a TBM host; the supporting 5 shoe is provided with microseismic modules at the supporting shoe; an annular slide rail is sleeved on the TBM host; fixed ends of horizontal oil cylinders are arranged on the TBM host; telescopic ends of the horizontal oil cylinders are connected with the annular slide rail; the annular slide rail is connected with fixed ends of bracing oil cylinders; and telescopic ends of the bracing oil cylinders are connected with 10 microseismic modules at a shotcrete bridge through a hydraulic damper. The present invention can realize the continuous whole-process microseismic monitoring in the TBM, and can follow the TBM boring to promote the monitoring interval synchronously to ensure the accuracy of the monitoring results. The present invention avoids frequent drilling, installation and disassembly of sensors in traditional drilling 15 monitoring, reduces the loss rate, and greatly reduces equipment cost and labor cost.6/6 4 103 Fig. 9 18 3 101 1 Fig. 10
