Description

Technical Field

[0001] This utility model relates to the field of prestressed anchor monitoring technology, specifically to a prestressed anchor monitoring device for slopes. Background Technology

[0002] Prestressed anchors are a widely used slope reinforcement technology that enhances the stability of rock, soil, or concrete structures by pre-applying tension (prestress).

[0003] In the actual installation process, holes need to be drilled on the slope surface first, then the prestressed anchors are placed into the holes, cement is poured into the holes, and finally the prestress is added to the prestressed anchors after the cement dries.

[0004] Over time, the prestress acting on prestressed anchors gradually decreases, reducing their effectiveness in reinforcing slopes and significantly increasing the risk of landslides. Conventional construction management standards require periodic increases in prestress on prestressed anchors to address this issue. However, in practice, factors such as time and distance often prevent the timely and routine implementation of these regular prestress increases. Therefore, the reinforced slopes still face the potential risk of uncontrollable landslides. To address this, the applicant proposes a monitoring system to mitigate these potential risks. Utility Model Content

[0005] In view of this, the present invention provides a slope prestressed anchor monitoring device, which can monitor slopes and reduce the risk of landslides.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A slope prestressed anchor monitoring device includes prestressed anchors arrayed on the slope surface. The device is characterized by a first monitoring component positioned between two adjacent prestressed anchors in the vertical direction. The first monitoring component includes a movable rod and a detection seat. The movable rod and the detection seat are respectively fixedly mounted on the two adjacent prestressed anchors in the vertical direction. The detection seat has a conical hole, and a first detection element is provided on the inner wall of the conical hole. The movable rod passes through the conical hole, and a stop block adapted to the structure of the conical hole is provided at one end of the movable rod near the detection seat. When relative displacement occurs between the two adjacent prestressed anchors in the vertical direction, the stop block can be inserted into the conical hole and compress the first detection element.

[0008] With the above structure, through the design of the stop block and the conical hole, when there is relative displacement between the two prestressed anchors in the vertical direction, the stop block can be forced to gradually move into the conical hole. When the stop block touches the first detection element, it indicates that a landslide has occurred, and the operator can be notified to increase the prestress in time to ensure the stability of the slope surface.

[0009] Preferably, the first detection element is a pressure sensor. With this structure, when the stop block moves into the conical hole, the pressure sensor detects the pressure applied by the stop block, enabling timely feedback on the relative displacement between two adjacent prestressed anchors in the vertical direction.

[0010] Preferably, the movable rod has a support section, which is fixedly mounted on the top of the prestressed anchor. This structure ensures that the movable rod is stably installed on the prestressed anchor.

[0011] Preferably, the movable rod has a rod-shaped portion, one end of which is hinged to the support section, and the stop block is fixed to the other end of the rod-shaped portion. This structure increases the overall structural strength of the movable rod and prevents the rod-shaped portion from breaking off at the support section.

[0012] Preferably, a second monitoring component is provided between two adjacent prestressed anchors in the horizontal direction. This second monitoring component is used to monitor whether relative displacement occurs between the two adjacent prestressed anchors in the horizontal direction. This structure avoids the possibility that two adjacent prestressed anchors in the vertical direction will simultaneously displace downwards, preventing the first monitoring component from failing to detect the displacement in time.

[0013] Preferably, the second monitoring component includes a connecting rod horizontally connected between the two prestressed anchors and a support seat disposed on one of the prestressed anchors, with a second detection element disposed between the connecting rod and the support seat. With this structure, when two adjacent prestressed anchors are positioned relative to each other in the horizontal direction, the connecting rod can move relative to the support seat, thereby allowing the second monitoring element to detect the movement.

[0014] Preferably, the second detection element is a spring, and a pressure sensor is disposed at one end of the second detection element near the support base. With this structure, when relative displacement occurs between two adjacent prestressed anchors in the horizontal direction, the movement of the connecting rod compresses the spring, thereby enabling the pressure sensor to detect the displacement promptly.

[0015] Preferably, the insertion depth of each prestressed anchor into the slope in the same vertical direction decreases gradually from top to bottom, while the insertion depth of each prestressed anchor into the slope in the same horizontal direction is the same. This structure ensures that in the event of a landslide, the lower prestressed anchor will shift, thus enabling the monitoring components to function effectively.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. The slope prestressed anchor monitoring device provided by this utility model uses a first monitoring component set between two adjacent prestressed anchors in the vertical direction. When relative displacement occurs between two adjacent prestressed anchors in the vertical direction, the stop block can be forced to move into the conical hole. When the first detection element is compressed, it can provide timely feedback, thereby reminding the operator to increase the prestress of the prestressed anchor and reduce the risk of slope landslide.

[0018] 2. The second monitoring component installed between two adjacent prestressed anchors in the horizontal direction effectively avoids the phenomenon that two adjacent prestressed anchors in the vertical direction will simultaneously shift downwards, while the first detection element cannot detect it, thus further improving the accuracy of the overall monitoring system.

[0025] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0026] like Figure 1 , Figure 3 and Figure 4As shown, a slope prestressed anchor monitoring device includes prestressed anchors 1 arrayed on the surface of a slope 7. A first monitoring component A is installed between two adjacent prestressed anchors 1 in the vertical direction. The first monitoring component A includes a movable rod 2 and a detection seat 3. The movable rod 2 and the detection seat 3 are respectively fixedly installed on two adjacent prestressed anchors 1 in the vertical direction. A conical hole 3a is formed on the detection seat 3. The movable rod 2 passes through the conical hole 3a. A first detection element 8 is formed on the inner wall of the conical hole 3a. A stop block 2b adapted to the structure of the conical hole 3a is formed at one end of the movable rod 2 near the detection seat 3. When two adjacent prestressed anchors 1 in the vertical direction experience relative displacement, the stop block 2b can be forced to move toward the inside of the conical hole 3a. When the stop block 2b approaches the first detection element 8 and applies force to it, the operator can know that the corresponding prestressed anchor 1 needs to be increased, thereby preventing landslides on the slope 7.

[0027] With this design, the first monitoring component A, which is set between two adjacent prestressed anchors 1 in the vertical direction, can force the stop block 2b to move into the conical hole 3a when there is relative displacement between the two adjacent prestressed anchors 1 in the vertical direction. After the first detection element 8 is subjected to pressure from the stop block 2b, it can promptly provide feedback to the operator, thereby reminding the operator to increase the prestress of the prestressed anchor 1 and reduce the risk of landslide on the slope 7.

[0028] In this embodiment, the first detection element 8 is a pressure sensor. The pressure sensor is electrically connected to a wireless transmission module. The wireless transmission module can collect the data detected by the pressure sensor and wirelessly transmit it to a computer or mobile device, thereby facilitating operators to monitor the status of the slope 7 and each prestressed anchor 1 in real time.

[0029] like Figure 2 As shown, the movable rod 2 also has a rod-shaped part 2a and a support section 2c. The support section 2c is fixedly installed on the top of the prestressed anchor 1, the rod-shaped part 2a is hinged to the support section 2c, and the stop block 2b is fixedly installed on the end of the rod-shaped part 2a away from the support section 2c. This design, through the hinge design, can increase the structural strength of the entire movable rod 2 and prevent the rod-shaped part 2a from breaking at the support section 2c.

[0030] like Figure 1 As shown, a second monitoring component B is installed between two adjacent prestressed anchors 1 in the horizontal direction. The second monitoring component B is used to monitor whether there is a relative displacement between two adjacent prestressed anchors 1 in the horizontal direction. This design avoids the first detection element 8 failing to detect synchronous displacement between two adjacent prestressed anchors 1 in the vertical direction, thereby ensuring the detection effect of the entire monitoring device.

[0031] Specifically, such as Figure 5As shown, the second monitoring component B includes a connecting rod 4 horizontally connected between two prestressed anchors 1 and a support seat 5 fixedly installed on one of the prestressed anchors 1. A second detection element 6 is installed between the connecting rod 4 and the support seat 5. The end of the connecting rod 4 away from the support seat 5 is fixedly installed on the other prestressed anchor 1.

[0032] In this embodiment, the second detection element 6 is a spring. The second detection element 6 is disposed on the side of the support base 5. A pressure sensor is also disposed at the end of the second detection element 6 near the support base 5. The pressure sensor is also electrically connected to a wireless transmission module. When there is a relative displacement between two adjacent prestressed anchors 1 in the horizontal direction, the connecting rod 4 can be positioned relative to the support base 5, thereby causing the spring to be compressed. The spring pressure can be detected by the pressure sensor and finally sent to a computer or mobile terminal through the wireless transmission module to remind the operator to increase the prestress in time.

[0033] like Figure 6 As shown, the insertion depth of each prestressed anchor 1 into the slope 7 in the same vertical direction gradually decreases from top to bottom. With this design, because the insertion depth of each prestressed anchor 1 in the vertical direction is different, the prestress applied by each prestressed anchor 1 is located at different levels of the slope 7. When a landslide occurs, the lower prestressed anchor 1 will deflect first due to the stress loss in the slope 7, thus enabling the first monitoring component A to play a monitoring role. The depth difference between two adjacent prestressed anchors 1 in the vertical direction is mainly determined by the specific dimensions of the slope 7 and the number of prestressed anchors 1 in the vertical direction of the slope 7. In this embodiment, the preferred depth difference between two adjacent prestressed anchors 1 in the vertical direction is 20 cm.

[0034] In addition, the depth to which each prestressed anchor 1 is inserted into the slope 7 in the same horizontal direction is the same. This design ensures that the detection accuracy of the first monitoring component A in each vertical direction remains consistent.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model. Those skilled in the art, under the guidance of the present utility model, can make various similar representations without departing from the spirit and claims of the present utility model, and such modifications all fall within the protection scope of the present utility model.
