[0022] In related technologies, when anchor cables experience stress relaxation due to dynamic stress, the common approach is to increase the anchor cable length or replace the anchor cable. However, lengthening or replacing the anchor cable increases construction difficulty and exacerbates stress loss in the surrounding rock. To address this technical problem, this invention discloses an anchor cable grouting device. The core concept of the device is that it includes: an anchor cable; a grouting bag embedded in the anchor cable for storing reinforcing grout; the reinforcing grout is used to control the anchor cable's bearing capacity; a monitoring module located within the anchor cable for monitoring the anchor cable's bearing capacity and location information; the anchor cable's bearing capacity information includes the anchor cable's stress change value; a first grouting pipe connected at one end to the grouting bag; and a grouting supply device connected to the other end of the first grouting pipe for injecting reinforcing grout into the corresponding grouting bag of the anchor cable through the first grouting pipe, based on the anchor cable's location information; the injection volume of the reinforcing grout is determined based on the anchor cable's bearing capacity information. This invention monitors the stress changes and location information of the anchor cables via a monitoring module. When the stress of the anchor cables changes, the grouting supply equipment can determine the grouting volume based on the anchor cable's bearing capacity information and inject reinforcing grout corresponding to the grouting volume into the corresponding grouting bag according to the anchor cable's location information.

[0032] like Figure 4 The diagram shows a structural block diagram of a monitoring module provided in an embodiment of the present invention. The monitoring module 03 may include a load-bearing force sensor 031, which is disposed at one end of the anchor cable 01. The anchor rod 011 can pass through the load-bearing force sensor 031. The load-bearing force sensor 031 can monitor the load-bearing force of the anchor cable 01, which may include the stress, tension, friction, etc. of the anchor cable 01.

[0033] In one embodiment, the anchor grouting device further includes: a signal conversion element 06; the signal conversion element 06 is connected to a load-bearing capacity sensor 031 and is used to receive the load-bearing capacity of the anchor cable 01 sent by the load-bearing capacity sensor 031; determine the load-bearing capacity information of the anchor cable 01 based on the load-bearing capacity of the anchor cable 01, and convert the load-bearing capacity information of the anchor cable 01 into a corresponding first electrical signal; and a grouting supply device 05 is used to receive the first electrical signal sent by the signal conversion element 06 and convert the first electrical signal into the corresponding load-bearing capacity information of the anchor cable 01.

[0034] In this embodiment of the invention, the signal conversion element 06 can be disposed inside or outside the anchor cable 01. The specific location of the signal conversion element 06 is not specifically limited here and can be set according to actual needs. The signal conversion element 06 can be connected to the load-bearing force sensor 031. The connection method can be wired or wireless.

The load-bearing force information may include the stress information of the anchor cable 01, and the force information of the anchor cable 01 is converted into a corresponding first electrical signal. For example, the load-bearing force sensor 031 can monitor the load-bearing force of the anchor cable 01 over a preset time period, wherein the stress in the load-bearing force during the preset time period decreases from 200KN to 150KN. The signal conversion element 06 can receive the load-bearing force within the preset time period sent by the load-bearing force sensor 031 and determine the load-bearing force information of the anchor cable 01 during the preset time period. This load-bearing force signal can be stress change information. The signal conversion element 06 can convert the bearing capacity information into a corresponding first electrical signal.

The anchor rod 011 can pass through the mechanical element 0311. When the load-bearing capacity of the anchor cable 01 changes, the mechanical element 0311 can undergo a corresponding physical change. The greater the change in load-bearing capacity, the greater the physical change in the mechanical element 0311. This physical change can be deformation. When the load-bearing capacity of the anchor cable 01 changes, the mechanical element 0311 can emit a physical signal corresponding to the change in load-bearing capacity through deformation. The mechanical element 0311 can also monitor the load-bearing capacity of the anchor cable 01 through deformation. Different physical changes in the mechanical element 0311 correspond to different load-bearing capacities of the anchor cable 01. The mechanical conversion element 0312 can be connected to both ends of the mechanical element 0311. The mechanical conversion element 0312 can monitor the physical changes in the mechanical element 0311 and then determine the load-bearing capacity of the anchor cable 01 based on the relationship between the physical transformation of the mechanical element 0311 and the load-bearing capacity of the anchor cable 01.

This position information also represents the position information of the corresponding anchor cable 01. The positioning element 0313 can be connected to the signal conversion element 06, and the connection method can be wired or wireless. The signal conversion element 06 can be disposed outside the anchor cable 01.

One end of the first pipe body 041 may be detachably connected to the grouting bag 02, and the other end of the first pipe body 041 may be movably connected to one end of the second pipe body 042. The other end of the second pipe body 042 may be connected to the grouting supply device 05. The first pipe body 041 and the second pipe body 042 may transport the reinforcing grout in the grouting supply device 05 to the grouting bag 02.

[0045] In this embodiment of the invention, there can be two first grouting pipes 04. One first grouting pipe 04 is connected to the first sub-bag 021, and the other first grouting pipe 04 can be connected to the second sub-bag 022. In this way, reinforcing grout can be injected into the first sub-bag 021 and the second sub-bag 022 through the two first grouting pipes 04 respectively. Furthermore, by adjusting the volume of reinforcing grout in the first sub-bag 021 and / or the volume of reinforcing grout in the second sub-bag 022, the anchoring section 015 of the corresponding relaxed anchor cable 01 can be reinforced. At the same time, the stress of the anchoring section 015 in the grouting area of ​​the anchor cable 01 can be precisely controlled, which makes up for the technical defect of the grouting technology of the grouting bag 02 in the prior art, which is limited to one-time grouting.

[0046] In one embodiment, the grouting supply device 05 includes: a second grouting pipe 051 connected to the other end of the first grouting pipe 04 for transmitting reinforcing grout; and a grouting module 052 connected to the second grouting pipe 051 for injecting reinforcing grout into the grouting bag 02 corresponding to the location information through the first grouting pipe 04 and the second grouting pipe 051.

[0047] In this embodiment of the invention, the grouting supply device 05 may include a second grouting pipe 051 and a grouting module 052. The second grouting pipe 051 may be connected to a plurality of first grouting pipes 04 for transmitting reinforcing grout.

The analysis module 053 can receive the bearing capacity information and location information sent by the monitoring module 03, and then perform analysis based on the bearing capacity information and location information to obtain the analysis result. The analysis result indicates how much reinforcing grout is injected into the grouting bag 02 corresponding to the location information of the anchor cable 01.

[0050] In one embodiment, the grouting supply device 05 is used to determine the amount of reinforcing grout to be injected based on the stress change value and the preset grouting mapping relationship when the stress change value is greater than the preset change value; the preset grouting mapping relationship characterizes the relationship between the stress change value and the grouting amount.

[0051] In this embodiment of the invention, the grouting supply device 05 can determine the amount of reinforcing grout to be injected into the grouting bag 02 based on the stress change value and the preset grouting mapping relationship.

[0052] In this embodiment of the invention, the specific process of injecting reinforcing grout into the grouting bag 02 can be as follows: After an earthquake occurs in a certain place, the anchor cable 01 will become loose, which will lead to stress relaxation. At this time, the monitoring module 03 can obtain the bearing capacity information and location information of the anchor cable 01. The location information can represent which anchor cable 01 in which place, that is, the location information can represent the monitoring point of the anchor cable 01 set in the tunnel support. The detection module can send the position information and bearing capacity information to the signal conversion element 06. The signal conversion element 06 can convert the bearing capacity information into a corresponding first electrical signal and the position information into a corresponding second electrical signal. Then, the first and second electrical signals are sent to the analysis module 053. The analysis module 053 can convert the first electrical signal into the corresponding bearing capacity information and the second electrical signal into the corresponding position information, thereby obtaining the position information and bearing capacity information of the anchor cable 01. Then, the analysis module 053 can determine the amount of reinforcing grout to be injected into the grouting bag 02 based on the bearing capacity information. Then, the analysis module 053 can control the grouting module 052 to inject the reinforcing grout corresponding to the injection volume into the grouting bag 02 corresponding to the anchor cable 01 through the first grouting pipe 04 and the second grouting pipe 051 according to the position information of the anchor cable 01.

[0053] Alternatively, when the monitoring module 03 detects that the bearing capacity of the anchor cable 01 is less than a preset threshold, it can send the detected bearing capacity and position information of the anchor cable 01 to the signal conversion element 06. The signal conversion element 06 converts the bearing capacity and position information of the anchor cable 01 into signals and sends them to the analysis module 053. The analysis module 053 can control the grouting module 052 to inject reinforcing grout into the grouting bag 02 corresponding to the anchor cable 01 according to the position information of the anchor cable 01. At this time, the monitoring module 03 can monitor the bearing capacity of the anchor cable 01 in real time and send it to the analysis module 053. When the bearing capacity of the anchor cable 01 meets the preset threshold, the analysis module 053 can control the grouting module 052 to stop injecting reinforcing grout into the grouting bag 02.
