Description

Technical Field

[0001] This utility model relates to the field of support technology construction, and in particular to a pipe-cable composite anchoring structure that facilitates the measurement of anchor cable tension. Background Technology

[0002] Anchor cables are structures used to reinforce and support soil or rock. In the construction field, they can play a role in reinforcing and supporting soil or rock, distributing loads, controlling groundwater levels, and improving foundation conditions, thus ensuring the safety and stability of the project.

[0003] However, as anchor cables play an increasingly important role in foundation pit engineering and are closely related to foundation pit safety, it is necessary to monitor the stress changes of anchor rods and anchor cables during foundation pit construction to analyze the safety status of the foundation pit. Currently, anchor cable stress monitoring mostly adopts the method of installing anchor cable stress gauges for measurement. For example, Chinese patent application with publication number CN117147035A discloses an anchor cable tension monitoring device and method, which sets the anchor cable axial force gauge between the end of the anchor cable located outside the ground and the anchor. After the anchor cable axial force gauge is installed and the anchor cable construction is completed, the anchor cable is prestressed and tensioned to record the initial load on the anchor cable axial force gauge, thereby obtaining the stress condition of the anchor cable. This measurement requires tensioning, which is cumbersome to operate and data acquisition is relatively complicated. Utility Model Content

[0004] The purpose of this invention is to provide a tube-cable composite anchoring structure that facilitates the measurement of anchor cable tension, addressing the problems of cumbersome operation and complicated data acquisition required for measuring anchor cable tension.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0006] A tube-cable composite anchoring structure for easy measurement of anchor cable tension includes an anchor cable, a sensor, and a bearing plate, wherein one end of the anchor cable passes through the bearing plate and is anchored by a second anchor.

[0007] The sensor is positioned between the second anchor and the bearing plate, and the sensor abuts against both the second anchor and the bearing plate. The sensor is used to collect the tension force on the anchor cable.

[0008] This application describes a pipe-cable composite anchoring structure for easy measurement of anchor cable tension. One end of the anchor cable passes through a bearing plate and is anchored through a second anchor. A sensor is positioned between the second anchor and the bearing plate, and the sensor is in contact with both the second anchor and the bearing plate. During construction, the end of the anchor cable with the bearing plate is placed at the bottom of the anchor hole. When the anchor cable is used, when it is under tension, the anchor cable drives the second anchor to press against the sensor, enabling the sensor to measure the tension of the anchor cable. By collecting the tension of the anchor cable through the sensor, the real-time stress condition of the anchor cable can be obtained, avoiding the conventional method of measuring the anchor cable stress by prestressing the anchor cable under test, making the operation simpler and more convenient.

[0009] As a preferred embodiment of this utility model, it also includes a data receiving end, to which the sensor can transmit the measured data.

[0010] The real-time stress of the anchor cable is monitored by sensors and the data is transmitted to an external data receiver. This facilitates the acquisition of the real-time stress of the anchor cable through the external data receiver, simplifying subsequent measurement operations and enabling real-time monitoring.

[0011] As a preferred embodiment of this utility model, it also includes a data output line, one end of which is connected to the sensor, and the other end of which is detachably connected to the data receiving end.

[0012] The data output line and the data receiver are detachably connected, which makes it easy to connect the data line to different types and functions of data receivers, thereby facilitating multiple analyses and utilizations of the sensor data.

[0013] As a preferred embodiment of this utility model, the data receiving end is further provided with a wireless signal transmitter.

[0014] By setting up a wireless signal transmitter at the data receiving end, the received data signal can be transmitted to other remote devices or uploaded to the network, thus facilitating remote monitoring.

[0015] As a preferred embodiment of this utility model, a protective tube is also included, which is sleeved on the data output line. Installing a protective tube on the data output line prevents damage or breakage during installation and extends the service life of the data output line.

[0016] As a preferred embodiment of this utility model, a protective cover is further included. The protective cover is disposed on the side of the bearing plate away from the anchor cable, and the sensor and the second anchor are located inside the protective cover. By providing a protective cover on the bearing plate and placing the sensor and the second anchor inside the protective cover, the sensor is protected from grout corrosion during grouting of the anchor hole, thereby ensuring the accuracy of the sensor measurement data during subsequent use in this application.

[0017] As a preferred embodiment of this utility model, it includes an anchor bolt;

[0018] The anchor rod is sleeved on the outside of the anchor cable. One end of the anchor rod abuts against the bearing plate, and the other end of the anchor rod is connected to a fastener for anchoring the anchor rod. A support structure is provided at the bottom of the fastener.

[0019] By installing an anchor rod on the outside of the anchor cable, with one end of the anchor rod abutting against the bearing plate and a fastener connected to the other end of the anchor rod, and a support structure provided at the bottom of the fastener, a pipe-cable composite anchoring structure is formed between the anchor cable and the anchor rod. This allows the sensor to measure the stress on the anchor cable in the pipe-cable composite anchoring structure, so as to better monitor the stress on the pipe-cable composite anchoring structure in real time.

[0020] As a preferred embodiment of the present invention, it further includes an anchor plate, which is located on the side of the support structure near the fastener, and the anchor plate abuts against the support structure, forming a cavity between the anchor plate and the support structure.

[0021] The end of the anchor bolt near the support structure and the fastener are both located inside the cavity, and the end of the anchor cable near the support structure passes through the anchor plate and is fixed to the outside of the anchor plate.

[0022] By setting up an anchor plate, a cavity is formed between the anchor plate and the support structure. The end of the anchor rod near the support structure and the fastener are located in the cavity, while the end of the anchor cable near the support structure passes through the cavity and is fixed to the outside of the anchor plate. This fixes one end of the anchor cable to the outside of the anchor plate, separating the anchor cable from the anchor rod and thus achieving separate stress on the anchor rod and the anchor cable. When it is necessary to apply prestress to the pipe-cable composite anchoring structure, prestress can be applied to the anchor cable on the outside of the anchor plate without affecting the anchor rod.

[0023] As a preferred embodiment of this utility model, it further includes a first anchor, which is disposed on the side of the anchor plate away from the anchor rod and abuts against the anchor plate. The first anchor is used to lock the anchor cable, facilitating the locking of the anchor cable through the first anchor.

[0024] As a preferred embodiment of this utility model, a grouting channel is provided between the anchor bolt and the anchor cable;

[0025] It also includes a data output line and a data receiving end. One end of the data output line is connected to the sensor, and the other end of the data output line passes through the grouting channel and is connected to the data receiving end located outside the anchor bolt.

[0026] A grouting channel is provided inside the anchor bolt, which allows the data output line to pass through the grouting channel and connect to the data receiving end located outside the anchor bolt. This transmits the sensor data to the data receiving end. Furthermore, the data output line passes through the grouting channel, thus avoiding placing the data output line outside the anchor bolt and preventing damage to the data output line during installation.

[0027] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0028] This application describes a pipe-cable composite anchoring structure for easy measurement of anchor cable tension. One end of the anchor cable passes through a bearing plate and is anchored through a second anchor. A sensor is positioned between the second anchor and the bearing plate, and the sensor is in contact with both the second anchor and the bearing plate. During construction, the end of the anchor cable with the bearing plate is placed at the bottom of the anchor hole. When the anchor cable is used, when it is under tension, the anchor cable drives the second anchor to press against the sensor, enabling the sensor to measure the tension of the anchor cable. By collecting the tension of the anchor cable through the sensor, the real-time stress condition of the anchor cable can be obtained, avoiding the conventional method of measuring the anchor cable stress by prestressing the anchor cable under test, making the operation simpler and more convenient.

[0039] Example 1

[0040] like Figures 1-4 As shown in the figure, the tube-cable composite anchoring structure for easy measurement of anchor cable tension described in this embodiment includes an anchor cable 2, a sensor 9 and a bearing plate 7. One end of the anchor cable 2 passes through the bearing plate 7 and is anchored by a second anchor 8.

[0041] Sensor 9 is positioned between the second anchor 8 and the bearing plate 7, and sensor 9 is in contact with both the second anchor 8 and the bearing plate 7. Sensor 9 is used to collect the tension force on the anchor cable 2.

[0042] This embodiment presents a tube-cable composite anchoring structure for easy measurement of anchor cable tension. One end of the anchor cable 2 passes through the bearing plate 7 and is anchored through the second anchor 8. The sensor 9 is positioned between the second anchor 8 and the bearing plate 7, and the sensor 9 abuts against both the second anchor 8 and the bearing plate 7. During construction, the end of the anchor cable 2 with the bearing plate 7 is placed at the bottom of the anchor hole 70. When the anchor cable 2 is used subsequently, when the anchor cable 2 is under tension, the anchor cable 2 drives the second anchor 8 to press against the sensor 9, enabling the sensor 9 to measure the tension of the anchor cable 2 under tension. By collecting the tension of the anchor cable 2 through the sensor 9, the real-time stress condition of the anchor cable 2 can be obtained, avoiding the conventional method of measuring the stress of the anchor cable 2 by prestressing the anchor cable under test, making the operation simpler and more convenient.

[0043] A preferred method, such as Figure 1 As shown, it also includes a data receiver 10, and the sensor 9 can transmit the measured data to the data receiver 10.

[0044] In the actual application of anchor cables, such as after the support construction, the sensor 9 monitors the real-time stress of the anchor cable 2 and transmits the data to the external data receiver 10. This facilitates the acquisition of the real-time stress of the anchor cable 2 through the external data receiver 10 in the later stages, simplifying the subsequent measurement operation and realizing real-time monitoring.

[0045] A preferred method, such as Figure 1 As shown, it also includes a data output line 20, one end of which is connected to the sensor 9, and the other end of which is detachably connected to the data receiver 10.

[0046] The data from the sensor 9 is transmitted to the data receiver 10 via the data output line 20. Furthermore, the data output line 20 and the data receiver 10 are detachably connected, which facilitates the connection of the data line with different types and functions of data receivers. This allows for various analyses and multiple uses of the sensor data. For example, the data output line 20 can be connected to a receiver with a display screen to observe the stress data of the cable-tube composite anchorage structure, or the data output line 20 can be connected to a receiver with analysis functions to perform statistical analysis on the stress of the cable-tube composite anchorage structure during actual use.

[0047] In a preferred embodiment, the end of the data output line 20 near the data receiving end 10 is provided with an encapsulation head;

[0048] The data receiver 10 has a connector, and the encapsulation head mates with the connector. The mate between the encapsulation head and the connector allows for the installation and removal of the data output line 20 and the data receiver 10.

[0049] In a preferred embodiment, the sensor 9 and the data receiver 10 transmit data wirelessly.

[0050] In a preferred embodiment, the data receiver 10 is also equipped with a wireless signal transmitter. By equipping the data receiver 10 with a wireless signal transmitter, the data receiver 10 can transmit the received data signals to other remote devices or upload them to the network, thereby facilitating remote monitoring.

[0051] A preferred method, such as Figure 3 As shown, it also includes a protective tube 30, which is sleeved on the data output line 20. The protective tube 30 is installed on the data output line 20 to prevent damage or breakage during installation and to extend the service life of the data output line 20.

[0052] like Figure 1 , Figure 3 As shown, it also includes a protective cover 80, which is disposed on the side of the bearing plate 7 away from the anchor cable 2, and the sensor 9 and the second anchor 8 are located inside the protective cover 80. By setting the protective cover 80 on the bearing plate 7 and placing the sensor 9 and the second anchor 8 inside the protective cover 80, during construction, the end of the anchor cable with the bearing plate is placed at the bottom of the anchor hole 70, and then concrete grout is injected into the anchor hole 70. At this time, the protective cover 80 can protect the sensor 9 and the second anchor 8 from grout corrosion, thereby ensuring the accuracy of the measurement data of the sensor 9 during subsequent use in this application.

[0053] In a preferred embodiment, the lower end of the anchor cable 2 is located inside the protective cover 80, that is, the lower end of the anchor cable 2 does not penetrate the protective cover 80, but is set in the area between the protective cover 80 and the bearing plate 7.

[0054] In this embodiment, the protective cover 80 refers to the enclosed area between the protective cover 80 and the support plate 7.

[0055] In a preferred embodiment, the lower end of the anchor cable 2 extends outside the protective cover 80, i.e., the lower end of the anchor cable 2 passes through the protective cover 80.

[0056] Example 2

[0057] like Figures 1-4 As shown, based on Embodiment 1, the pipe-cable composite anchoring structure of this application, which facilitates the measurement of anchor cable tension, includes an anchor rod 1;

[0058] An anchor rod 1 is sleeved on the outside of the anchor cable 2. One end of the anchor rod 1 abuts against the bearing plate 7, and the other end of the anchor rod 1 is connected to a fastener 4 for anchoring the anchor rod 1. A support structure 3 is provided at the bottom of the fastener 4.

[0059] An anchor rod 1 is fitted on the outside of the anchor cable 2. One end of the anchor rod 1 abuts against the bearing plate 7, and the other end of the anchor rod 1 is connected to a fastener 4. A support structure 3 is provided at the bottom of the fastener 4, so that the anchor cable 2 and the anchor rod 1 form a pipe-cable composite anchoring structure. This allows the sensor 9 to measure the stress on the anchor cable 2 in the pipe-cable composite anchoring structure, so as to better monitor the stress on the pipe-cable composite anchoring structure in real time later.

[0060] A preferred method, such as Figure 2 As shown, it also includes an anchor plate 5, which is located on the side of the support structure 3 near the fastener 4, and the anchor plate 5 abuts against the support structure 3, forming a cavity 90 between the anchor plate 5 and the support structure 3.

[0061] The end of the anchor bolt 1 closest to the support structure 3 and the fastener 4 are both located inside the cavity 90. The end of the anchor cable 2 closest to the support structure 3 passes through the anchor plate 5 and is fixed to the outside of the anchor plate 5.

[0062] By setting up an anchor plate 5, a cavity 90 is formed between the anchor plate 5 and the support structure 3. The end of the anchor rod 1 near the support structure 3 and the fastener 4 are both located in the cavity 90. The end of the anchor cable 2 near the support structure 3 passes through the cavity 90 and is fixed to the outside of the anchor plate 5, thereby fixing one end of the anchor cable 2 to the outside of the anchor plate, so that the anchor cable 2 and the anchor rod 1 are fixed separately, thus realizing the separate force of the anchor rod 1 and the anchor cable 2. When it is necessary to apply prestress to the pipe-cable composite anchoring structure to increase the structural performance due to engineering needs, prestress can be applied to the anchor cable 2 on the outside of the anchor plate 5 without affecting the anchor rod 1.

[0063] In a preferred embodiment, the support structure 3 is preferably a pad or a frame beam.

[0064] like Figure 2 As shown, the anchor plate 5 has a sidewall 51, which is arranged in a ring and abuts against the support structure 3. The anchor plate 5 abuts against the support structure 3 through the sidewall 51, forming a cavity 90 between the support structure 3 and the anchor plate 5. The sidewall 51 abuts against the side of the support structure 3 closest to the fastener 4. When the anchor plate 5 is subjected to external pressure, it can transmit the external pressure to the support structure 3, which then transmits it to the anchor rod 1 or the ground, thus achieving force distribution.

[0065] Furthermore, some existing prestressing devices, when applying prestress to the anchor cable 2, abut against the side of the anchor plate 5 away from the anchor rod 1. This results in an external force being applied to the anchor plate 5 when applying prestress to the anchor cable 2. In this application, since the side wall 51 abuts against the support structure 3, the anchor plate 5 transmits the external force it receives to the support structure 3 through the side wall 51, preventing the external force from being transmitted to the anchor rod 1 or fastener 4. This achieves the goal of applying prestress to the anchor cable 2 outside the anchor plate 5 without affecting the anchor rod 1 and fastener 4, making the structural stress of this application more reasonable and the prestressing application safer and more convenient.

[0066] like Figure 2 As shown, the fastener 4 is located on the side of the support structure 3 away from the anchor rod 1 and abuts against the support structure 3. The fastener 4 is used to anchor the anchor rod 1. By setting the fastener 4 in the cavity to lock the anchor rod 1, the anchor rod 1 abuts against the support structure 3 at intervals, so that the anchor rod 1 and the anchor cable 2 are fixed separately.

[0067] In a preferred embodiment, the upper part of the anchor rod 1 is provided with external threads, and the fastener 4 is provided with internal threads. The fastener 4 is threadedly connected to the anchor rod 1, and the fastener 4 is preferably a nut.

[0068] In a preferred embodiment, a first anchor 6 is further included. The first anchor 6 is located on the side of the anchor plate 5 away from the anchor rod 1 and abuts against the anchor plate 5. The first anchor 6 is used to lock the anchor cable 2. By locking the anchor cable 2 with the first anchor 6, the anchor cable 2 is fixed to the outside of the anchor plate 5, allowing the anchor cable 2 to be fixed separately from the anchor rod 1. This facilitates the separate stress distribution between the anchor cable 2 and the anchor rod 1 when prestressing needs to be applied to the anchor cable 2 for subsequent construction purposes.

[0069] like Figure 1 , Figure 3 As shown, there is a grouting channel 11 between the anchor bolt 1 and the anchor cable 2;

[0070] It also includes a data output line 20 and a data receiving end 10. One end of the data output line 20 is connected to the sensor 9, and the other end of the data output line 20 passes through the grouting channel 11 and is connected to the data receiving end 10 located outside the anchor rod 1.

[0071] An anchor bolt 1 is provided with a grouting channel 11, which allows the data output line 20 to pass through the grouting channel 11 and connect to the data receiving end 10 located outside the anchor bolt 1, so as to transmit the data of the sensor 9 to the data receiving end 10. The data output line 20 passes through the grouting channel 11, thereby avoiding the data output line 20 being placed outside the anchor bolt 1, and thus avoiding damage to the data output line 20 during installation.

[0072] When installing the pipe-cable composite anchoring structure described in this application, the end of the anchor rod 1 with the bearing plate 7 is placed at the bottom of the anchor hole 70, and then grout is injected into the anchor hole 70 to complete the installation of the pipe-cable composite anchoring structure.

[0073] like Figure 2 As shown, a grout-stopping ring 50 is connected to the side of the support structure 3 away from the anchor plate 5. The grout-stopping ring 50 is circumferentially arranged on the outside of the anchor rod 1, as shown. Figure 4 As shown, an anchor hole 70 is drilled in the soil layer 60, and then the anchor rod 1 and its auxiliary structure are installed in the anchor hole 70. After installation, grout is injected into the anchor hole 70, and the grout stop ring 30 can prevent the grout from overflowing from the anchor hole 70, thus avoiding environmental pollution.

[0074] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
