Abstract
Description
Technical Field
[0001] This invention belongs to the field of anchor bolt testing technology, specifically relating to an anchor bolt pull-out force testing system and method. Background Technology
[0002] In geotechnical engineering, in order to maintain the stability of disturbed engineering structures, it is necessary to use anchor bolt support for the surrounding rock mass. Anchor bolt support technology is a commonly used active support technology in the field of geotechnical engineering. It improves the integrity, peak strength and bearing capacity of the surrounding rock structure by providing certain constraints to the surrounding rock mass. In order to ensure that the anchor bolt can apply the specified anchoring force to the surrounding rock mass, a pull-out test must be carried out.
[0003] Existing pull-out force tests are generally conducted using hydraulic pull-out testing equipment. This equipment applies pull-out force to the anchor rod using hydraulic pressure and detects the displacement of the anchor rod using a single displacement sensor to obtain the pull-out force test data. However, during the pull-out test, the hydraulic loading equipment may cause the concrete foundation to sink in the soil surface due to the reaction force. At the same time, the anchor rod will also deform due to the force during the pull-out test. Therefore, using a single displacement sensor cannot effectively obtain these test data.

Detailed Implementation
[0017] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0018] Example 1: like Figure 1 As shown, an anchor pull-out force detection system of the present invention includes: Anchor rod 003, the lower end of which is fixedly installed inside the concrete base 001, and the upper end of which is located above the concrete base 001; A pad 100 is fitted around the anchor rod 003 and installed on the concrete base 001. A pad bracket 101 is also provided on the pad 100, and the pad bracket 101 extends horizontally outward to the soil base surface 002 outside the concrete base 001. The loading device 102 is installed and fixed to the pad 100. The loading device 102 is sleeved on the anchor rod 003. The lower end of the loading device 102 is fixedly installed on the pad 100. The upper end of the loading device 003 is provided with a force-applying clamp 103 for clamping the anchor rod 003. The first pull-out force detection component is mounted on the pad bracket 101; The second pull-out force detection component is disposed on the outer side of the upper end of the anchor rod 003; The data processing cloud 108, the first pull-out force detection component, the second pull-out force detection component and the loading device 102 are respectively connected to the data processing cloud 108 via signals.
[0019] In this invention, the top bracket 104 is installed on the upper end of the anchor rod 003, and the extension length of the top bracket 104 is greater than the extension length of the pad bracket 101; as an explanation of the installation of the top bracket 104, as follows... Figure 1As shown, the top bracket 104 is installed on the upper end of the anchor rod 003 through the ring clamp 1041; by setting the pad 100 on the concrete base 001, the loading device 102 can be stably installed and fixed. During the test, the loading device 102 applies a pull-out force, which is transmitted to the anchor rod 003 through the force clamp 103, so that the pull-out force test of the anchor rod 003 can be carried out.
[0020] Based on the above structural components, see Figure 1 The first pull-out force detection component includes a first distance sensor 105, and the second pull-out force detection component includes a second distance sensor 106 and a third distance sensor 107. The first distance sensor 105, the second distance sensor 106, the third distance sensor 107, and the loading device 105 are all signal-connected to the data processing cloud 108. The second distance sensor 106 and the third distance sensor 107 are horizontally arranged on the outer side of the upper end of the anchor rod 003. A top support 104 is horizontally arranged at the upper end of the anchor rod. The free end of the top support 104 extends horizontally outward along the anchor rod for a length greater than the extension length of the pad support 101. The first distance sensor 105 is installed on the lower side of the end of the pad support 101, the second distance sensor 106 is installed at the far end of the top support 104, and the third distance sensor 107 is installed at the near end of the top support 104 and corresponds to the upper side of the pad support 101. On the soil surface... 002 is embedded with a first reflective surface 109 and a second reflective surface 110 respectively, which are matched with the first distance sensor 105 and the second distance sensor 106. A third reflective surface 111, matched with the third distance sensor 107, is installed on the upper side of the pad support 101. During the pull-out force test, the second distance sensor 106 sends a distance measurement signal, which is reflected back to the second distance sensor 106 by the second reflective surface 110, thereby detecting the distance between the top support 104 and the soil base surface 002. The first distance sensor 105 sends a distance measurement signal, which is reflected back to the first distance sensor 105 by the first reflective surface 109, thereby detecting the distance between the pad support 101 and the soil base surface 002. The third distance sensor 107 sends a distance measurement signal, which is reflected back to the third distance sensor 107 by the third reflective surface 111, thereby detecting the distance between the top support 104 and the pad support 101. Changes in the above distance measurement data can reflect: First, during the pull-out force test, the reaction force may cause the pad 100 and the concrete base 001 to sink. The change in the distance measurement data of the first distance sensor 105 can reflect the sinking of the pad 100 and the concrete base 001. Secondly, during the pull-out force test, the anchor rod 003 itself deforms in the length direction due to the force, and the change in the distance measurement data of the third distance sensor 107 can reflect the tensile deformation of the anchor rod 003. Finally, during the pull-out force test, the anchor rod 003 was pulled out of the concrete base 001 due to the force. The change in the distance measurement data of the second distance sensor 106 can reflect the overall length change of the anchor rod 003.
[0021] Thus, the detection system of the present invention can detect the displacement changes caused by various factors during the anchor pull-out force test. Compared with the measurement by a single displacement sensor, it provides more test data and improves the detection of various displacement variables during the pull-out force test.
[0022] Based on the above detection system, please continue to refer to Figure 1 , Figure 1 The dashed lines in the diagram represent signal connections. The system also includes: The first ranging sensor 105, the second ranging sensor 106, the third ranging sensor 107, and the loading device 102 are all connected to the data processing cloud 108 via signals. The data processing cloud 108 can receive and process ranging data and perform data processing and analysis.
[0023] As a description of the loading device 102, specifically as follows: Figure 1As shown, the loading device 102 includes a hydraulic loader 1021, a jack 1022, and a hydraulic sensor 1023. The bottom end of the hollow jack is fixedly installed on the pad 100. The force-applying clamp 103 is installed at the movable end of the jack 1022 (hollow jack) and fixedly sleeved on the outer wall of the anchor rod 003. The hydraulic loader 1021 is connected to the hydraulic port of the jack 1022 (hollow jack) through a hydraulic pipeline. A hydraulic sensor 1023 is provided, which is connected to the data processing cloud signal. The hydraulic sensor 1023 is used to detect the pressure generated when hydraulic oil is supplied to the jack 1022 through the hydraulic pipeline, thereby obtaining the force on the jack. The jack 1022 is a commonly used hydraulic jack for pulling the anchor rod. The jack 1022 (hollow jack) is a hollow hydraulic jack. The hydraulic loader 1021 is connected to the jack 1022 through a hydraulic pipeline. 22 are connected. The hydraulic loader 1021 can be a hand pump. During the test, hydraulic oil is applied to the jack 1022 by the hydraulic loader 1021, causing the movable end of the jack 1022 to extend. The movable end of the jack 1022 pushes the force-applying clamp 103 clamped on the anchor rod 003 to generate a pull-out force. The pull-out force is transmitted to the anchor rod 003 through the force-applying clamp 103, thus enabling the pull-out force test of the anchor rod 003. The reaction force of 022 causes the pad 100 and concrete base 001 to sink. The change in the distance measurement data of the first distance sensor 105 can reflect the sinking displacement of the pad 100 and concrete base 001. The anchor rod 003 is pulled out of the concrete base 001 by the jack 1022 due to the force. The change in the distance measurement data of the second distance sensor 106 can reflect the overall length change of the anchor rod 003, thereby detecting the length of the anchor rod 003 that has been pulled out.
[0024] Example 2: The detection method for anchor bolt pull-out resistance is implemented using the detection system of Example 1, such as... Figure 2 As shown, the pull-out force testing method includes the following steps: Step S100: Equipment Installation: In the specific installation process, the pad 100 is first installed and fixed to the concrete base 001. Then, the loading device 102 is installed on the pad 100 and the anchor rod 003 is clamped and fixed by the force-applying clamp 103. Next, a top bracket 104 is installed on the top of the anchor rod 003, and a pad bracket 101 is set on the pad 100. Finally, a first distance sensor 105 is installed on the pad bracket 101, and a third distance sensor 107 and a second distance sensor 106 are installed outward from the top bracket 104 in sequence. Step S200: Obtain initial data: The height of the first ranging sensor 105 from the soil surface 002 of the detection pad bracket 101 is denoted as follows: The second ranging sensor 106 detects the height of the top support 104 from the soil surface 002 and records it as... The third ranging sensor 107 detects the height of the top bracket 104 from the pad bracket 101 and records it as follows: ,in , indicating the number of pull-out tests; Acquired by the first ranging sensor 105 As initial data, it is acquired by the second ranging sensor 106. As initial data, it is acquired through the third ranging sensor 106. As initial data, and , as well as Transmitted to the data processing cloud 108; Step S300: Pull-out test: Multiple sets of pulling forces, ranging from small to large, are applied by the loading device 102. Tests were conducted, and distance test data for each set of pull-out force tests were acquired using the first distance sensor 105, the second distance sensor 106, and the third distance sensor 106, respectively. , as well as ; Step S400: Data Processing Cloud 108 processes the acquired pull-out force and corresponding distance test data to obtain anchor bolt quantitative data under different pull-out forces.
[0025] In addition, the data processing cloud 108 includes a data processing module, a storage module, a permissions module, a user authentication module, and a reporting module; The data processing module is connected to the first distance sensor, the second distance sensor, the third distance sensor, and the hydraulic sensor signal on the loading device, respectively. It is used to receive each set of pull-out force data and the corresponding monitoring data of the first distance sensor, the second distance sensor, and the third distance sensor, and associate each set of pull-out force data and the corresponding monitoring data as a test dataset. The storage module is used to store each test dataset; The permissions module is used to manage permissions for the storage module; The user verification module is used to verify and save visitor information in the data processing cloud. Visitor information mainly includes user name, ID information and permission level. The reporting module is used to analyze each test dataset, generate test reports, and store each test report in the storage module.
[0026] Specifically, the data processing module of cloud-based data processing platform 108 processes the quantitative data of anchor bolts under different pull-out forces as follows: S410: Calculate the change in height of the support plate 101 from the soil surface 002 between the two consecutive measurements. This reflects the settlement variable of the concrete base 001 during each pull-out force test. Calculate the change in the distance between the top support 104 and the soil surface between the two measurements: This reflects the elongation variable of the anchor rod 003 relative to the soil base surface 002 during each pull-out force test. Calculate the change in height between the top support 104 and the pad support 101 in the two preceding and subsequent measurements: This reflects the deformation of anchor rod 003 under tension during each pull-out force test. It should be understood that the elongation of anchor bolt 003 relative to the soil surface 002 is... The tensile deformation of anchor rod 003 The sum of the actual length pulled out of the anchor bolt and the total length can be calculated. and The difference is used to obtain the actual length of the anchor rod pulled out during each pull-out test. .
[0027] S420: The data processing module receives each set of pull-out force data and the corresponding monitoring data from the first, second, and third distance measuring sensors, and associates each set of pull-out force data and the corresponding monitoring data as a test dataset. ; S430: The report module analyzes each test dataset and generates a test report; S440: Various test datasets All test reports are stored through the storage module, while the permission module manages permissions for the storage module. S450: When a user accesses the data processing cloud, the user verification module verifies the visitor information. Once the verification is successful, the visitor can access the data processing cloud.
[0028] When the permission module manages permissions for the storage module, it can be divided into the following two levels: Level 1 permission: Under this permission, users can only access each test dataset. This level of permission is mainly applicable to ordinary construction workers, so that ordinary construction workers can check the test datasets. Level 2 access: Under this access level, users can access each test dataset and the corresponding test report. This level of access is mainly applicable to construction designers, so that they can view the test dataset and test report and carry out construction design. In this invention, when accessing each test dataset, the permission module receives the user's access request, retrieves the permission identifier assigned to the user's permission level from the storage module, and establishes the correspondence between the user and the permission identifier assigned to the permission level. The allowed data identifiers in the storage areas of the storage modules corresponding to each permission level are parsed into the user authentication module to save the operation request; where the data identifiers are the identifiers corresponding to the test datasets that different users can access; The permission module obtains a data identifier from the user verification module based on the permission identifier. The data identifier corresponds to the test dataset stored in the storage module. The module intercepts the operation request corresponding to the permission identifier and determines whether the user's assigned permission level includes the operation request. If so, the operation request is accepted, allowing the user to inspect the test dataset or access the test reports corresponding to each test dataset. Otherwise, the operation request is rejected, and access to the test dataset and its corresponding test reports is not allowed. This invention enables unified allocation and storage control of access permissions, achieving permission control when accessing each test dataset.

Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.

This reflects the deformation of the anchor rod under tension during each pull-out force test. Elongation of the anchor bolt relative to the soil surface 002 The tensile deformation of anchor rod 003 The sum of the actual length of the anchor bolt pulled out is calculated. and The difference is used to obtain the actual length of the anchor rod pulled out during each pull-out test. ; S420: The data processing module receives each set of pull-out force data and the corresponding monitoring data collected by the first distance sensor, the second distance sensor, and the third distance sensor, and associates each set of pull-out force data and the corresponding monitoring data as a test dataset. S430: The reporting module analyzes each of the test datasets and generates a test report; S440: Each of the aforementioned test datasets and each of the aforementioned test reports are stored through the storage module, and the permission module manages the permissions of the storage module; S450: When a user accesses the data processing cloud, the user verification module verifies the visitor information. When the verification is successful, the visitor can access the data processing cloud.
10. The pull-out force testing method according to claim 8, characterized in that: In step S440, the permission module storage module performs permission management specifically into first-level permissions and second-level permissions: Level 1 access: Applicable to ordinary construction workers, allowing them to inspect the test datasets. Under Level 1 access, users can only access each test dataset. Level 2 access: Applicable to construction designers, allowing them to view test datasets and test reports for construction design. Under Level 2 access, users can access each test dataset and its corresponding test report.
