In the grouting process, gas may exist, and when the gas appears, the grouting fullness is not accurately judged by only observing the overflow condition of the grouting liquid through the first auxiliary pipeline, so that the embodiment is further provided with the monitoring mechanism 11, and the accurate judgment of the grouting material fullness in the drilling hole 13 is realized by the cooperation of the monitoring mechanism 11 and the slurry discharging mechanism 7.
The monitoring mechanism 11 consists of a second shell 11-1, a third shell 11-2, a second connecting rod 11-3, a metal rod 11-4, a magnet 11-5, an electric signal monitoring mechanism 11-6, a signal conversion and emitter 11-7, a lead 11-8, a piezoelectric ceramic plate 11-9, an electric signal excitation device 11-10 and a power supply device 11-11.
When the monitoring mechanism is used, the second shell 11-1 is fixedly arranged at the upper edge of the inner wall of the drilling hole 13, the third shell 11-2 is connected with the second shell 11-1, the second shell and the third shell are combined together to form an outer shell of the monitoring mechanism 11, the size of the third shell 11-2 is slightly smaller than that of the second shell 11-1, and the third shell 11-2 can move relative to the second shell 11-1.
The two magnets 11-5 are symmetrically arranged at the upper end and the lower end of the inner side wall of the second shell 11-1, the electric signal monitoring mechanism 11-6 and the signal conversion and emission device 11-7 are fixedly arranged at the upper end of the inner side wall of the second shell 11-1, the electric signal excitation device 11-10 and the power supply device 11-11 are fixedly arranged at the lower end of the inner side wall of the second shell 11-1, and the piezoelectric ceramic plate 11-9 is fixedly arranged on the inner side wall of the closed end of the second shell 11-1.

When the detection is carried out, the power supply device 11-11 transmits electric quantity to the electric signal excitation device 11-10, the electric signal excitation device 11-10 stimulates the piezoelectric ceramic plate 11-9 to vibrate, and in the vibration process of the piezoelectric ceramic plate 11-9, the second connecting rod 11-3 drives the third shell 11-2 and the metal rod 11-4 to move;
when the third shell 11-2 is in different media (air, unset slurry and set slurry), the operation of the third shell 11-2 is hindered to different degrees, the speed of the metal rod 11-4 for cutting the magnetic induction line is changed, the current generated in the metal rod 11-4 is changed, the current is transmitted to the electric signal monitoring mechanism 11-6 through the lead 11-8, the electric signal detected by the electric signal monitoring mechanism 11-6 is converted into a digital signal by the signal conversion and transmitter 11-7, the digital signal is transmitted to the display and control system 4, and the display and control system 4 judges whether grouting is full and slurry is set according to the change rule of the digital signal.
As shown in fig. 9 (a), when the monitoring mechanism 11 is in the air, the generated current is relatively large; as shown in fig. 9 (b), when the monitoring mechanism 11 is in the slurry, the vibration of the third housing 11-2 is blocked, and the generated current is reduced; as shown in fig. 9 (c), when the slurry is solidified, the metal rod 11-4 cannot cut the magnetic induction line, and thus no current is generated.

as shown in fig. 10 (c), in the process of discharging large bubbles, firstly, the discharging three-way ball 7-13 is rotated to enable the opening end of the main pipeline of the slurry discharging mechanism to be communicated with the second auxiliary pipeline, the repairing material on the upper layer of the drilling hole 13 is discharged through the slurry discharging mechanism 7, and then the grouting channel 8 and the slurry discharging mechanism 7 work simultaneously until the slurry discharging mechanism 7 discharges the uniform repairing material and the monitoring mechanism 11 detects that the repairing material is full;
as shown in fig. 10 (d), in the process of cleaning the pipeline, the discharge ball position adjusting rod 7-14 and the filling ball position adjusting rod 8-3 are rotated to enable the inside of the slurry discharging mechanism 7 and the inside of the grouting channel 8 to be communicated with air, and the inside of the pipeline is flushed by clean water.
