The present invention relates to the field of microseismic monitoring, and more
particularly relates to an embedded microseismic monitoring device with a TBM.
With the continuous improvement of the machinery manufacturing level, the
construction of tunnel projects has gradually developed towards mechanization and
modularization. As mechanized tunnel construction equipment with high integration, a
TBM has the characteristics of high boring speed and high safety, and has been widely
used in the construction of various rock tunnel projects.
Rock burst is one of the main problems during TBM boring. For tunnel projects
with poor rock quality, joint fissures in the rock layer, or large buried depth and high
stress, rock burst occurs easily when rock mass is disturbed by excavation, causing
TBM jamming, equipment damage, or even major personnel and property losses.
Microseismic monitoring has been proven in practice to be an effective technology for
monitoring and early warning of the rock burst. The time, space and energy
distribution of a rock fractures event during TBM boring are monitored to guide the
control of construction progress to a certain extent, so as to prevent the rock burst.
Through inspection of practical projects, it is found that microseismic monitoring
is often required within a certain distance only after the excavation of a tunnel face
during TBM boring. Therefore, considering the necessity and the economy,
microseismic sensors are often alternately installed and removed to promote a
monitoring interval. However, the method requires frequent installation and removal
of the sensors to follow the excavation progress, which is cumbersome in steps,
time-consuming, laborious, and not conducive to the popularization and application of
the microseismic monitoring technology in TBM boring projects.
The purpose of the present invention is to provide an embedded microseismic
monitoring device with a TBM in view of the above defects in the prior art.
To achieve the above purpose, the present invention adopts the following

host.
Each bracing oil cylinder corresponds to two horizontal oil cylinders, and a part
of the annular slide rail connected with the fixing seats of the bracing oil cylinders is connected with the telescopic ends of the corresponding two horizontal oil cylinders.
The inner side of the part connected with the fixed ends of the bracing oil

supporting leg is embedded in a slide rail guide groove; the slide rail guide groove is
arranged on the outer wall of the TBM host; and the extension direction of the slide
rail guide groove is parallel to the axis of the TBM host.

Compared with the prior art, the present invention has the following beneficial
effects:
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 the sensors in
traditional drilling monitoring, reduces the loss rate, and greatly reduces equipment cost and labor cost.

For the convenience of understanding and implementing the present invention
for those ordinary skilled in the art, the present invention will be further described in
detail below in conjunction with the embodiments. It should be understood that the
implementation examples described herein are only used to illustrate and explain the
present invention, not to limit the present invention.
An embedded microseismic monitoring device with a TBM includes a
supporting shoe 102 arranged on a TBM host 101; the supporting shoe 102 is
provided with microseismic modules 2 at the supporting shoe; an annular slide rail 4
is sleeved on the TBM host 101; fixed ends of horizontal oil cylinders 5 are arranged
on the TBM host 101; telescopic ends of the horizontal oil cylinders 5 are connected
with the annular slide rail 4; the annular slide rail 4 is connected with fixed ends of
bracing oil cylinders 8; and telescopic ends of the bracing oil cylinders 8 are
connected with microseismic modules 9 at a shotcrete bridge through a hydraulic
damper 13.
The microseismic sensors 11 are generally arranged in one group with an interval
of 30-50 m, each group including four microseismic sensors. Considering the actual
characteristics of the TBM host 101, a dual-monitoring section arrangement solution
is adopted. When the TBM host 101 bores, a cutter head cuts the rock and produces
strong vibration, which is not conducive for the microseismic sensors 11 to monitor a
rock fracture signal. Therefore, the first section is arranged at the supporting shoe 102,
15-20 m away from a boring surface, where the impact of mechanical vibration is
relatively small. Meanwhile, considering the internal equipment arrangement
conditions of the TBM host 101, the second monitoring section is arranged in front of
the shotcrete bridge, 60-80 m away from the boring surface.
Four microseismic modules 2 at the supporting shoe are arranged. Each
microseismic module 2 at the supporting shoe includes a recovery device 10, a
microseismic sensor 11 and a protecting cover 12; the microseismic sensor 11 is
arranged in a sensor installation hole of the supporting shoe 102 through the recovery
device 10; the protecting cover 12 is arranged at an opening of the sensor installation
hole of the supporting shoe 102; and the inner side of the protecting cover 12 is
connected with the end part of the microseismic sensor 11. As shown in Fig. 1, a
unidirectional sensor is selected as the microseismic sensor 11. In order to facilitate
the maintenance and disassembly of the microseismic sensor 11, the recovery device
10 is used to fix the microseismic sensor 11. The bottom of the sensor installation hole
should be as close to the outer shield surface of the supporting shoe 102 as possible;
and the opening of the sensor installation hole is blocked with the protecting cover 12.
As shown in Fig. 2, four microseismic modules 9 at the shotcrete bridge are
arranged. Each microseismic module 9 at the shotcrete bridge includes an arc-shaped
supporting plate 22, a protecting sleeve 1501, a sealing cover 24, a recovery device 10
and a microseismic sensor 11; one end of the protecting sleeve 1501 is connected with
the inner wall of the arc-shaped supporting plate 22, and the other end of the
protecting sleeve 1501 is connected with the sealing cover 24; and the microseismic
sensor 11 is arranged in the protecting sleeve 1501 through the recovery device 10.
The unidirectional sensor is selected as the microseismic sensor 11. The section at the
shotcrete bridge has no established equipment to be continuously close to the tunnel
wall. Thus, the bracing oil cylinders 8 are required to be installed at the section of the
shotcrete bridge. Four bracing oil cylinders 8 are evenly distributed along the annular
slide rail 4. The telescopic direction of the telescopic ends of the bracing oil cylinders
8 is the radial direction of the TBM host 101. The bracing oil cylinders 8 are used to
lift the microseismic modules 9 at the shotcrete bridge on the section of the shotcrete
bridge to attach to the tunnel wall, so as to ensure the quality of the monitored
microseismic signal. A protecting sleeve rib plate 1502 is arranged between the side
wall of the protecting sleeve 1501 and the arc-shaped supporting plate 22.
When the microseismic module 2 at the supporting shoe is installed, firstly, the recovery device 10 is installed on the microseismic sensor 11, and then the microseismic sensor 11 is installed into the sensor installation hole. The microseismic sensor 11 is rotated so that the recovery device 10 (the recovery device 10 is the prior art, e.g., the recovery device disclosed in the patent document of Application Publication No. CN105818538A) braces the hole wall to ensure that the protecting cover 12 is installed after fastening. The protecting cover 12 is connected to the supporting shoe 102 by using screws, and the fixed cylinder on the inner side of the protecting cover 12 is closely attached to the microseismic sensor 11. An extension electric cable 16 of the microseismic sensor 11 penetrates from a hole reserved in the protecting cover 12 and is connected to a collector 17. The telescopic end of each bracing oil cylinder 8 is connected with a damper connecting plate 23; the telescopic end of the hydraulic damper 13 is connected with the damper connecting plate 23; the fixed end of the hydraulic damper 13 is connected with the sealing cover 24; a spring 14 is sleeved outside the hydraulic damper 13; and both ends of the spring 14 are respectively abutted against the damper connecting plate 23 and the sealing cover 24. The hydraulic damper 13 has the functions of reducing vibration and reducing the influence of mechanical vibration on the microseismic sensor 11 during TBM operation. The spring 14 has the function of bearing the pressure of the bracing oil cylinder 8 and transmitting the pressure to the protecting sleeve 1501. The protecting sleeve 1501 has the functions of receiving microseismic waves and realizing dust sealing. The protecting sleeve rib plate 1502 has the function of dispersing the pressure to the arc-shaped supporting plate 22 so that the entire arc-shaped supporting plate 22 is close to the tunnel wall. The recovery device 10 has the functions of fixing the microseismic sensor 11 and conducting the microseismic wave to the microseismic sensor 11. During installation, firstly, the recovery device 10 is installed on the micro-seismic sensor 11, and then the microseismic sensor 11 and the recovery device 10 are put into the protecting sleeve 1501. The microseismic sensor 11 is rotated so that the recovery device 10 braces the inner wall of the protecting sleeve 1501. The protecting sleeve 1501 is connected with the sealing cover 24; the electric cable 16 penetrates from the hole reserved on the side of the protecting sleeve 1501; meanwhile, the spring 14 is installed on the hydraulic damper 13; the fixed end of the hydraulic damper 13 is connected with the sealing cover 24; the spring 14 is sleeved outside the hydraulic damper 13; both ends of the spring 14 are respectively abutted against the damper connecting plate 23 and the sealing cover 24; and the damper connecting plate 23 is connected with the telescopic end of the hydraulic damper 13 to complete the installation work of the microseismic module 9 at the shotcrete bridge.
The inner side of the part of the annular slide rail 4 connected with the fixed ends
of the bracing oil cylinders 8 is provided with a supporting leg 21; the supporting leg
21 is embedded in a slide rail guide groove 103; the slide rail guide groove 103 is
arranged on the outer wall of the TBM host 101; and the extension direction of the
slide rail guide groove 103 is parallel to the axis of the TBM host 101. Both sides of
the supporting leg 21 are provided with rollers 7 that can roll along the slide rail guide
groove 103, and a roller limiting plate 6 is arranged at a notch of the slide rail guide
groove 103.
Both sides of the supporting leg 21 are connected with the rollers 7 through a
spherical roller bearing. The rollers 7 are placed in the slide rail guide groove 103 and
can slide along the direction of the slide rail guide groove 103. At the same time, a
pulley limiting plate 6 is used to limit the rolling direction of the rollers to prevent the
rollers 7 from falling out of the slide rail guide groove 103. The pulley limiting plate 6
is connected to the notch of the slide rail guide groove 103 by screws.
A horizontal oil cylinder supporting ring 104 is fixedly sleeved on the TBM host
101; a plurality of horizontal oil cylinders 5 are uniformly distributed along the
circumferential direction of the TBM host 101; a fixing seat of each horizontal oil
cylinder 5 is connected with the horizontal oil cylinder supporting ring 104; and the
telescopic direction of the horizontal oil cylinders 5 is parallel to the axial direction of
the TBM host 101. Preferably, each bracing oil cylinder 8 corresponds to two
horizontal oil cylinders 5, and the part of the annular slide rail 4 connected with the
fixing seat of the bracing oil cylinder 8 is connected with the telescopic ends of the
corresponding two horizontal oil cylinders 5. The protecting sleeve rib plate 1502 is arranged between the side wall of the protecting sleeve 1501 and the arc-shaped supporting plate 22. In order to prevent eccentric loads from causing rapid wear on the equipment during long-term operation, the installation of the components at the shotcrete bridge shall ensure that the central axes of the microseismic modules 9 at the shotcrete bridge, the bracing oil cylinders 8 and the supporting legs 21 at the shotrete bridge are coincident, perpendicular to the central axis of the TBM host 101 and intersectant with the central axis of the TBM host 101. In order to ensure that the horizontal oil cylinder 5 pushes or pulls back the annular slide rail 4 smoothly without twisting, each bracing oil cylinder 8 corresponds to two horizontal oil cylinders 5, and the part of the annular slide rail 4 connected with the fixing seat of the bracing oil cylinder 8 is connected with the telescopic ends of two corresponding horizontal oil cylinders. The central axes of the two horizontal oil cylinders 5 are symmetrically arranged on both sides of the central axis of the corresponding bracing oil cylinder 8. Four microseismic sensors 11 of the microseismic modules 2 at the supporting shoe and four microseismic sensors 11 of the microseismic modules 9 at the shotcrete bridge are connected with an 8-channel data collector 17, and the 8-channel data collector 17 is arranged near the shotcrete bridge. The microseismic sensors 11 are installed and then connected to the data connector 17 through the electric cable 16; eight microseismic data collected by the data connector 17 are transmitted to a server 19 on the ground surface through an optical cable 18; and the server 19 transmits the eight microseismic data to a display terminal 20. A complete TBM boring cycle includes a boring travel and a step change travel. The step change travel generally takes only a few minutes to complete. Therefore, the present invention mainly focuses on microseismic monitoring in the boring travel. In the TBM boring travel, the supporting shoe 102 braces the tunnel wall, and a supporting shoe oil cylinder pushes the TBM host 101 to move forward. At this time, the microseismic module 2 at the supporting shoe depends on the close attachment between the supporting shoe 102 and the tunnel wall to receive the microseismic wave. The microseismic module 9 at the shotcrete bridge depends on the pressure applied by the bracing oil cylinder 8 to attach to the tunnel wall and receive the microseismic wave. The annular slide rail 4 and the rollers 7 ensure that the bracing oil cylinder 8 and the microseismic modules 9 at the shotcrete bridge can move relative to the TBM host 101, and the horizontal oil cylinder 5 controls the moving distance of the annular slide rail 4. During TBM boring, the bracing oil cylinder 8 applies sufficient pressure; and the telescopic end of the horizontal oil cylinder 5 contracts and keeps synchronous with the movement of the TBM host 101 to ensure that the microseismic module 9 at the shotcrete bridge is stationary relatively to the tunnel wall. In the TBM step change travel, the telescopic end of the bracing oil cylinder 8 contracts; a piston rod of the horizontal oil cylinder 5 is extended and reset; and then the telescopic end of the bracing oil cylinder 8 is re-extended to brace the microseismic module 9 at the shotcrete bridge to the tunnel wall. This process is cycled in this way. In the TBM boring travel, after the microseismic signals received by all the microseismic sensors 11 are sent back to the server 19, the microseismic monitoring software automatically realizes the identification, filtering and noise reduction, onset time picking, positioning and energy calculation of the microseismic signal waveform. After the step change travel is ended, the position coordinates of the microseismic modules 9 at the shotcrete bridge and the microseismic modules 2 at the supporting shoe are automatically updated according to the moving distances of the supporting shoe 102 and the annular slide rail 4 to realize the automatic whole-process microseismic monitoring of the TBM. The specific embodiments described herein are merely examples to illustrate the spirit of the present invention. Those skilled in the art of the present invention can make various modifications or supplements to the described specific embodiments or replace the embodiments in similar ways, without departing from the spirit of the present invention or going beyond the scope defined by the appended claims.
