  The injection amount information acquiring unit 32 is, for example, configured as a flow meter and an integrating flow meter, and the flow rate of the grout material G injected from the injection pump 12 and the integrated flow rate of the grout material G injected into the filling path 22 I am measuring. The injection amount information acquisition unit 32 may be configured only by a flow meter. In this configuration, the control unit 16 calculates the integrated flow rate of the grout material G injected into the filling path 22 based on the flow rate obtained from the flow meter and the elapsed time from the start of injection of the grout material G by the injection pump 12. I'm asking. In the present embodiment, the injection amount information acquiring unit 32 is electrically connected to the network module 38A.

  In the pressure information acquisition unit 34 in the present embodiment, the grout material G is configured to be passed through the inner cylinder 34 b. When the grout material G is passed through the inner cylinder 34b, the grout material G presses the inner cylinder 34b in the circumferential direction, and the inner cylinder 34b expands.

In the injection management information display unit 48, the flow rate, injection amount, pressure and temperature of the grout material G obtained by the injection amount information acquiring unit 32, the pressure information acquiring unit 34 and the temperature information acquiring unit 36 of the injection managing unit 14 Information is displayed in real time.

  On the display screen 26a, below the grout injection information display unit 44, the pressure information display unit 46, and the injection management information display unit 48, information indicating the filling state of the grout material G in the filling path 22 is displayed. . Specifically, a plurality of filling state information display units 52 for displaying the filling state information obtained by the filling path diagram 50 schematically showing the filling path 22 and the filling state information acquiring units 18A, 18B, 18C, 18D It is arranged.

  In the present embodiment, the plurality of filling state information display units 52 include filling state information display units 52A, 52B, 52C, and 52D. In the present embodiment, the filling state information display unit 52A corresponds to the filling state information acquisition unit 18A, the filling state information display unit 52B corresponds to the filling state information acquisition unit 18B, and the filling state information display unit 52C is the filling state information The filling state information display unit 52D corresponds to the filling state information acquiring unit 18D, which corresponds to the acquiring unit 18C.

  In the present embodiment, the path of the filling path 22 is schematically illustrated in the filling path diagram 50, and a portion corresponding to the position where the filling state information acquisition units 18A, 18B, 18C, 18D are arranged in the filling path 22. The notification units 54A, 54B, 54C, and 54D are disposed in the

  In the present embodiment, the notification units 54A, 54B, 54C, and 54D are configured to change the display state according to the filling information in the filling state information acquisition units 18A, 18B, 18C, and 18D. In the present embodiment, the notification unit 54 is configured as a lamp that can switch on and off states on the display screen 26a as an example. Specifically, when the filling state information acquiring unit 18 does not detect the filling state of the grout material G, the notifying unit 54 is turned off, and the filling state information acquiring unit 18 detects the filling state of the grout material G The notification unit 54 is turned on.

  The detection of the filling state in the filling state information acquiring unit 18 and the display of the filling information in the filling state information display unit 52 will be described with reference to FIGS. 5 and 6. In the following description, the filling state information acquisition unit 18B and the filling state information display unit 52B will be described as an example.

  FIG. 5A shows a state in which the grout material G is injected to a position (injection side) before the position where the filling state information acquiring unit 18B is disposed in the filling path 22. In this state, since the grout material G does not reach the detection region R of the filling state information acquiring unit 18B, the filling state information acquiring unit 18B can not detect the reflected light from the grout material G, and the grout material G can not be detected. Is not detected. Therefore, the filling state information acquiring unit 18B transmits a signal to the control unit 16 as the non-filling state. In the present embodiment, as an example, the filling state information acquiring unit 18B changes the voltage of the current sent from the filling state information acquiring unit 18B to the control unit 16 according to the intensity of the reflected light received by the light receiving unit. The control unit 16 detects the filling state and the non-filling state in the filling state information acquiring unit 18B according to the voltage. In the present embodiment, the control unit 16 uses the voltage value as the detection intensity.

  As shown in FIG. 5B, when the control unit 16 receives a signal (voltage according to the non-filling condition) of the non-filling condition of the filling condition information acquisition unit 18B, the control unit 16 enters the non-filling condition in the filling condition information display unit 52B. The detection result is displayed at the position of the corresponding detection intensity. Specifically, the detection intensity corresponding to the non-filling state is displayed as a solid line S extending with time.

  Next, in FIG. 6A, when the filling of the grout material G in the filling path 22 proceeds from the state of FIG. 5A and the grout material G reaches the inside of the detection region R of the filling state information acquisition unit 18B, the grout material Since the light receiving unit receives the light reflected from G, the filling state information acquiring unit 18B detects the grout material G. Thereby, the filling state information acquiring unit 18B changes the voltage of the current to the control unit 16. The control unit 16 determines that the filling state information acquiring unit 18B has switched from the non-filling state to the filling state by the change of the voltage.

  As shown in FIG. 6B, when the control unit 16 receives the signal of the filling state of the filling state information acquiring unit 18B, the display of the solid line S in the filling state information display unit 52B is based on the detection intensity according to the non-filling state. It switches to the position of the detection intensity according to the filling state.

  In FIG. 6B, as an example, the filling state information acquiring unit 18B detects the grout material G at time t2, and the control unit 16 does not display the solid line S at a position corresponding to the time t2 in the filling state information display unit 52B. Switch from the filling state to the filling state. Thereby, the worker who monitors the filling management system 10 can grasp that the filling state information acquiring unit 18B has detected the grout material G at time t2, and as a result, the operator can change the filling state information acquiring unit in the filling path 22. It can be determined that the grout material G is filled at the position where the 18B is disposed. Note that times t1, t2, t3, and t4 in the filling state information display unit 52 indicate, for example, the elapsed time from the start of the injection of the grout material G.

  Referring again to FIG. 4, the display screen 26a displays the temporal transition of the integrated injection amount of the grout material G in the grout material injection amount information display unit 44, the filling path diagram 50, and the filling state information display units 52A, 52B, 52C. , 52D are displayed. Thereby, while confirming the temporal transition of the injection amount of the grout material G injected into the filling path 22, the filling state of each filling state information acquiring unit 18 disposed in the filling path 22 is the filling state information display portion 52A. , 52B, 52C, 52D. As a result, the filling state of the grout material G in the filling path 22 can be confirmed in real time in the injection of the grout material G in the filling path 22 and the filling operation.

  In the present embodiment, the accumulated injection amount of the grout material G filled in the filling path 22 and the filling state in the filling path 22 can be simultaneously confirmed on the display screen 26a in real time. As a result, when any abnormality (for example, leakage etc.) is detected during the grout material G injection operation, the operator can confirm the abnormality condition more quickly and appropriately, thus eliminating the abnormality condition. To control the injection speed of the grout material G or temporarily interrupt the injection of the grout material G to wait for the residual air to escape from the filling path 22 or to perform appropriate processing such as confirmation of the leakage point Can.

  Further, in the present embodiment, in the filling route diagram 50, the notification unit 54 is provided in the portion corresponding to the position where the filling condition information acquiring unit 18 is disposed in the filling route 22, and the filling condition information acquiring unit 18 When the filling state is detected, the display state of the notification unit 54 changes on the display screen 26a, so that the grasping of the filling state can be easily grasped visually.

<<< Example of Modification of Embodiment >>>
(1) In the present embodiment, the filling state information acquisition unit 18 detects only the switching between the non-filling state and the filling state, but instead of this configuration, for example, filling state information acquisition in the filling path 22 The liquid level of the grout material G at the position where the section 18 is disposed may be detected, and the temporal transition of the detection distance between the filling state information acquiring unit 18 and the liquid level may be displayed on the filling state information display unit 52 .

  Specifically, in the filling state information acquiring unit 18, the distance between the filling state information acquiring unit 18 and the liquid surface of the grout material G is measured, and the voltage of the current sent to the control unit 16 is changed according to the distance. Thus, the filling state of the grout material G is reflected on the filling state information display unit 52.

  In FIG. 8A, the grout material G reaches the detection region R of the filling state information acquiring unit 18B in the filling path 22, and the liquid level of the grout material G is detected by the filling state information acquiring unit 18B. In this state, since the liquid level of the grout material G is immediately after being detected by the filling state information acquiring unit 18B, the filling state of the grout material G in the filling state information display unit 52 shown in FIG. The solid line S shown starts to extend from the unfilled state toward the filled state.

  Next, as shown in FIG. 9A, when the filling of the grout material G in the filling passage 22 proceeds and the liquid surface of the grout material G rises at the position corresponding to the filling state information acquiring unit 18B, the filling state information is acquired The distance between the portion 18 and the liquid surface of the grout material G becomes short. As a result, the voltage of the current sent from the filling state information acquiring unit 18B toward the control unit 16 changes, and the solid state S indicating the filling state of the grout material G in the filling state information display unit 52 shown in FIG. Extends further from the state shown in FIG. 8 (B) toward the filling state.

  As shown in FIG. 10A, when the filling of the grout material G in the filling path 22 proceeds and the filling of the grout material G at the position corresponding to the filling state information acquisition unit 18B is completed, the state shown in FIG. In the filling state information display unit 52, a solid line S indicating the filling state of the grout material G extends along the level of the filling state in which the grout material G is filled.

  In this modification, the grout material at the position where the filling state information acquiring unit 18 is disposed is not to detect that the change of the filling state in the filling state information acquiring unit 18 is merely switched from the non-filling state to the filling state. It is possible to measure the filling situation of G with time transition. Then, the control unit 16 causes the filling state information display unit 52 to reflect the temporal transition of the obtained filling state of the grout material G. Thereby, the worker who monitors the filling management system 10 can confirm the change of the filling state in each filling state information acquisition unit 18 in real time, and the injection of the grout material G in the filling path 22 and the filling operation are more appropriate. Can be monitored.

(2) In the present embodiment, the notification unit 54 is provided in the portion corresponding to the position provided in the filling state information acquiring unit 18 of the filling path diagram 50 of the display screen 26a, but the notification unit 54 is not provided. It is also good.

(3) In the present embodiment, the filling path diagram 50 is displayed on the display screen 26a, but instead of this configuration, the filling path diagram 50 is not displayed as shown in FIG. The material injection amount information display unit 44, the pressure information display unit 46, the injection management information display unit 48, and the filling state information display unit 52, which is filling information, may be displayed.

(4) In the present embodiment, the filling state information acquiring unit 18 is configured as a reflection type optical sensor, but may be configured by another detection sensor such as an ultrasonic sensor or an electric signal (electrode type).
