Description
Technical Field
[0001] This invention belongs to the field of design platform technology, specifically a mechatronics design platform for information technology services in underground special caverns. Background Technology
[0002] A cavern is a warehouse or cave excavated underground. These artificial caves are mainly used to store various items, including supplies, equipment, and even vehicles. They are typically used in different fields, such as military, industrial, and civilian applications. The construction of caverns usually requires consideration of various factors such as geology, soil, and water level. The construction process may require the use of techniques such as blasting, excavation, and support. Once completed, the interior of the cavern may also require waterproofing, ventilation, and lighting to ensure the safety of stored items and ease of use. The design platform, by establishing an information model, reflects the underground spatial environment and underground pipeline system layout of the cavern, helping to conduct pre-simulation of multiple 3D models and rationally select the spatial layout and structural form of underground engineering.
[0003] Due to the complex geological conditions of tunnels, the numerous difficulties in design and construction, and the many unpredictable factors, it is crucial to conduct dynamic monitoring and feedback. The key is to optimize the monitoring scheme, improve the accuracy of monitoring, and reduce the monitoring cost, so that the design platform can play a better role and achieve better results in tunnel construction. Summary of the Invention
[0004] To overcome the shortcomings of existing technologies and solve the aforementioned technical problems, this invention proposes an integrated electromechanical design platform for information technology services in underground special caverns.
[0005] The technical solution adopted by this invention to solve its technical problem is as follows: This invention proposes an integrated electromechanical design platform for underground special cavern information technology services, including an information modeling unit, a dynamic design unit, a construction monitoring unit, and a shared pan-tilt unit. The construction monitoring unit collects measurement values during cavern construction and optimizes design details; the construction monitoring unit includes:
[0006] A mobile module for moving within the excavated cavern;
[0007] The first monitoring module collects information about the excavated cavern and is located within the mobile module. The first monitoring module includes a rock stratum detection plate and a leakage detection plate. The rock stratum detection plate is used to detect the rock strata in the initial state of the excavated cavern, providing parameters for cavern expansion. The leakage detection plate is used to detect the internal moisture content of the initial state of the excavated cavern, providing excavation parameters for the cavern.
[0008] The second monitoring module collects information about the excavated tunnel after construction and is installed on the inner wall of the tunnel. The second monitoring module includes a wall monitoring panel, a rock surface monitoring panel, and a seepage monitoring panel. The wall monitoring panel monitors the concrete walls of the tunnel and collects parameters from the construction after excavation. The rock surface monitoring panel monitors changes in rock surface parameters after concrete pouring. The seepage monitoring panel detects seepage parameters on the concrete walls after pouring.
[0009] A data processing module is used to process and analyze the data collected by the first monitoring module and the second monitoring module.
[0010] The transmission module is used to upload data from the second monitoring module to the data processing module. The transmission module is equipped with measuring points evenly distributed, and each measuring point is equipped with a second monitoring module. A triangular measuring line system is used to arrange the measuring line network to connect each measuring point, and the relative displacement between the measuring points is completed through the measuring lines arranged in a set of independent measuring line networks.
[0011] Preferably, the data processing module employs a 3D design system based on the Skyline platform. The design platform collects data on the excavated cavern through the first monitoring module and sends it to the data processing module. The continued excavation and reinforcement of the cavern are adjusted accordingly based on the data from the first monitoring module. The second monitoring module performs long-term monitoring of the reinforced cavern, providing data references for the early excavation design, mid-term reinforcement design, and later electromechanical design of the cavern.
[0012] The design process of a 3D design system is as follows:
[0013] Based on the data uploaded by the first monitoring module and the data from the previous cave information modeling, the data is constructed using 3D Max and converted into Skyline's unique lightweight xpl2 data format. It is then loaded into the FLY project file using the 3DModel command. Finally, the parameters and attributes of the model are set to adjust the location, direction, size, and shape of the cave excavation.
[0014] Preferably, the FLY project file is generated by TerraExplorer Pro and is an index file for 3D data, containing network space and data addresses. That is, it integrates the data parameters of MPT 3D terrain data address, point data address, model data address, 2D plan view address, and image data address into a single FLY project file. By loading the 3DModel command, it realizes the display of 3D data, data information tree directory, and 2D navigation map information tree display. After clicking on a child node in the information tree, a unique object 3D positioning fly-in display effect is realized on the Skyline platform.
[0015] Preferably, the system framework of the 3D design system is designed as a three-layer structure: presentation layer, middleware layer, and data layer. The presentation layer is the client system operation interface layer, which implements corresponding functions through user commands. The middleware layer provides services for data transmission and Skyline function interface. The data layer is used by the data processing module to store and manage data in the database of cave collection and processing, for extraction by the 3D design system.
[0016] Preferably, in the three-dimensional design system,
[0017] Presentation layer design: Web engineering projects developed using a visual integrated development environment and the Java language;
[0018] The design of the middle layer: a 3D data system platform is built using the TerraExplorer Pro secondary development function library;
[0019] Data layer design: Data is stored on the server in the form of FLY files with access control encryption; based on the characteristics of the underground tunnel project, a large amount of excavation construction data needs to be stored and queried. Therefore, the attribute data of a large number of spatial objects is stored in the database of the shared cloud platform using storage technology.
[0020] Preferably, the location of the measuring point within the cave is referred to as the monitoring section. The measurement data of the monitoring section is transmitted to the data processing module, which uses a judgment system to perform a preliminary judgment on the data.
[0021] The ultimate relative displacement value X0 refers to the percentage of the maximum subsidence of the arch within the tunnel relative to the tunnel height, or the percentage of the maximum change in horizontal clearance relative to the tunnel excavation width. The ultimate relative displacement value is mainly used to determine the reliability of measurement data, the stability of initial support, and the end time of monitoring measurements.
[0022] The allowable relative displacement value refers to the allowable relative displacement value of the initial support of the tunnel, which is based on the distance of the measuring point from the excavation face and is obtained through the limit relative displacement of the initial support.
[0023] The span of the cavern is B;
[0024] The judgment is expressed as:
[0025] Allowable relative displacement value: X 1B =65%X0;X 2B =90%X0;X nB =100%X 0; ;
[0026] X represents the measured displacement value:
[0027] When X≦X1B / 3 or X≦X 2B At 3:00, reduce the monitoring frequency and continue construction;
[0028] When X 1B / 3≦X≦2X 1B / 3 or X 2B / 3≦X≦X 2B At 3 o'clock, increase the monitoring frequency and strengthen support measures;
[0029] When X≧2X 1B / 3 or X ≥ 2X 2B At 3 o'clock, increase the monitoring frequency and suspend construction.
[0030] Preferably, the transmission module further includes a local area network and a wireless transmission device, with one wireless transmission device connected to all the measuring points of every five monitoring sections; the data processing module is equipped with a data receiving device for every five wireless transmission devices, the wireless transmission devices send data to the data receiving devices through the local area network, and the data receiving devices send the data to the data processing module through wired transmission.
[0031] Preferably, the construction monitoring unit includes a measuring device, and a second monitoring module is installed inside the measuring device. The measuring device is used for the monitoring work of the second monitoring module.
[0032] The beneficial effects of this invention are as follows:
[0033] 1. The mechatronics design platform for underground special cavern information technology services described in this invention, when geological conditions are not ideal, first excavates a tunnel with a small space that is easy to excavate; then, a mobile module drives a first monitoring module into the tunnel to conduct on-site inspection of the rock strata and water leakage; subsequently, the first monitoring module transmits the collected data to the data processing module via wired transmission. The design platform analyzes and processes the data collected by the first monitoring module, providing data support for the subsequent secondary excavation and formation of the cavern. This allows the design platform to adopt different construction methods and measures for primary and secondary cavern excavation, improving ease of use.
[0034] 2. The mechatronics design platform for underground special cavern information technology services described in this invention, through the coordinated operation of a first monitoring module, a second monitoring module, and a special surveying network layout, enables accurate analysis of construction dynamic monitoring data. Under the same conditions of monitoring points, equipment, and personnel, the platform allows for a more rational distribution of monitoring points and surveying lines, reducing bad points and invalid data. Simultaneously, the improved accuracy of measurement data enhances the accuracy of back-analysis results, leading to more precise and reasonable basic mechanical parameters obtained through back-calculation, thus laying a solid foundation for numerical calculations of the cavern's surrounding rock and support structure.

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0042] Example 1:
[0043] An integrated electromechanical design platform for information technology services in underground special caves, as shown in the attached drawings of the specification. Figures 1-4 As shown, it includes an information modeling unit, a dynamic design unit, a construction monitoring unit, and a shared pan-tilt unit. The construction monitoring unit collects measurement values during the construction of the tunnel and optimizes design details. The construction monitoring unit is characterized by comprising:
[0044] A mobile module for moving within the excavated cavern;
[0045] The first monitoring module collects information about the excavated cavern and is located within the mobile module. The first monitoring module includes a rock stratum detection plate and a leakage detection plate. The rock stratum detection plate is used to detect the rock strata in the initial state of the excavated cavern, providing parameters for cavern expansion. The leakage detection plate is used to detect the internal moisture content of the initial state of the excavated cavern, providing excavation parameters for the cavern.
[0046] The second monitoring module collects information about the excavated tunnel after construction and is installed on the inner wall of the tunnel. The second monitoring module includes a wall monitoring panel, a rock surface monitoring panel, and a seepage monitoring panel. The wall monitoring panel monitors the concrete walls of the tunnel and collects parameters from the construction after excavation. The rock surface monitoring panel monitors changes in rock surface parameters after concrete pouring. The seepage monitoring panel detects seepage parameters on the concrete walls after pouring.
[0047] A data processing module is used to process and analyze the data collected by the first monitoring module and the second monitoring module.
[0048] The transmission module is used to upload the data in the second monitoring module to the data processing module. The transmission module is uniformly equipped with measuring points, and each measuring point is equipped with a second monitoring module. A triangular measuring line system is used to arrange the measuring line network to connect each measuring point. The relative displacement between the measuring points is completed through the measuring lines arranged in a set of independent measuring line networks.
[0049] Specifically: The tunnel is constructed using conventional excavation methods. When geological conditions meet the excavation requirements, the design platform directly performs the excavation of the tunnel in one go. First, advance support is installed for the tunnel, which requires full utilization of the steel frame erected in the previous cycle. This involves mechanical excavation followed by spraying an 8cm thick layer of concrete to seal the tunnel face, and then spraying an initial 4cm thick layer of concrete as initial and temporary support. A temporary steel frame is then erected on top. After drilling and installing system anchor bolts, concrete is sprayed again to achieve the designed thickness. When geological conditions are not ideal, the design platform first excavates a tunnel with a small space that is easy to excavate. Then, the moving module carries the first monitoring module into the tunnel to conduct on-site testing of the rock strata and water leakage. Subsequently, the first monitoring module transmits the collected data to the data processing module via wired transmission. The design platform analyzes and processes the data collected by the first monitoring module, providing data support for the subsequent tunnel expansion and secondary tunnel construction. This allows the design platform to adopt different construction methods and measures for primary and secondary tunnel construction, improving ease of use.
[0050] The triangular surveying system, through the conventional triangular surveying network layout, utilizes singular value decomposition combined with analytical methods for estimating solution resolution and variance. For independent surveying network layout schemes, it derives a calculation formula using the minimum norm as the optimal surveying network criterion. This formula is consistent with conventional engineering surveying network layout calculations. By combining this triangular surveying network layout calculation formula with monitoring during the secondary formation of the underground tunnel construction process, a basis is provided for the back-calculation of relevant parameters of the underground structure and the correct layout of the surveying network. An independent surveying network refers to a set of survey lines that uniquely determines the displacement value of each measuring point after excluding rigid body displacement. In other words, using a set of independently laid-out surveying lines to measure the relative displacement between measuring points uniquely determines the displacement of each measuring point, improving the data acquisition and transmission efficiency of tunnel construction, enhancing the real-time performance of monitoring, and enabling the design platform to provide effective support for tunnel excavation.
[0051] Furthermore, through the coordinated operation of the first monitoring module, the second monitoring module, and a special surveying network layout, the accuracy analysis of construction dynamic monitoring data allows for a more rational distribution of monitoring points and surveying lines under the same conditions of measuring points, equipment, and personnel, while reducing bad points and invalid data. Simultaneously, the improved accuracy of the measurement data enhances the accuracy of the back-analysis results, making the derived basic mechanical parameters more precise and reasonable, thus laying a solid foundation for the numerical calculation of the tunnel's surrounding rock and support structure.
[0052] Example 2:
[0053] Based on Example 1, the data processing module adopts a 3D design system based on the Skyline platform. The design platform collects data on the excavated cavern through the first monitoring module and sends it to the data processing module. The continued excavation and reinforcement of the cavern are adjusted accordingly based on the data from the first monitoring module. The second monitoring module conducts long-term monitoring of the reinforced cavern, providing data references for the early excavation design, mid-term reinforcement design, and later electromechanical design of the cavern.
[0054] The design process of a 3D design system is as follows:
[0055] Based on the data uploaded by the first monitoring module and the data from the previous cave information modeling, the data is constructed using 3D Max and converted into Skyline's unique lightweight xpl2 data format. The data is then loaded into the FLY project file using the 3DModel command. Finally, the parameters and attributes of the model are set to adjust the location, direction, size, and shape of the cave excavation.
[0056] The FLY project file, generated by TerraExplorer Pro, is an index file for 3D data, containing network space and data addresses. Specifically, it integrates data parameters such as MPT 3D terrain data addresses, point data addresses, model data addresses, 2D plan view addresses, and image data addresses into a single FLY project file. Through loading with the 3DModel command, it displays 3D data, a data information tree directory, and a 2D navigation map information tree. Clicking on a child node in the information tree enables a unique 3D object positioning and fly-in display effect on the Skyline platform.
[0057] The system framework of the 3D design system is designed with a three-layer structure: presentation layer, middleware layer, and data layer. The presentation layer is the client system operation interface layer, which implements corresponding functions through user commands. The middleware layer provides services for data transmission and Skyline function interface. The data layer is used by the data processing module to store and manage data in the database of cave collection and processing, for extraction by the 3D design system.
[0058] In the three-dimensional design system
[0059] Presentation layer design: The development tools of the visual integrated environment are used to develop web projects using the Java language. JavaScript is used to call the functional functions in Skyline for secondary development. The page layout adopts the layout of a web page and combines it with a hyperlink frame for layout optimization.
[0060] The design of the intermediate layer utilizes the TerraExplorer Pro secondary development function library to build a three-dimensional data system platform, providing powerful three-dimensional spatial auxiliary decision support and analysis functions for underground engineering.
[0061] Data layer design: Data is stored on the server in the form of FLY files with access control encryption; based on the characteristics of the underground tunnel project, a large amount of excavation construction data needs to be stored and retrieved. Therefore, the attribute data of a large number of spatial objects is stored in the database of the shared cloud platform using storage technology.
[0062] Specifically, the Skyline platform mainly consists of three components: TerraBuilder, TerraExplorer, and TerraGate. TerraBuilder is responsible for constructing 3D terrain model data and spatial object model data. TerraExplorer mainly implements functions such as 3D data operation and analysis. TerraGate is a server-side platform for publishing 2D data sharing, and client users can log in and access the database via the Internet. Skyline supports development in multiple languages and provides rich API interfaces. It can not only realize 3D data browsing operations, information tree, layer, and object creation and management, but also includes a database extension module to connect with other databases and perform data storage, query, and update operations. It has the capacity to accommodate massive amounts of data, avoiding problems with the storage of massive monitoring data during the construction of large caverns, improving the stability of monitoring data storage and retrieval, and facilitating the deployment of the design platform during the cavern construction process.
[0063] The storage technology used is NHibernate, an object-relational database mapping tool for the .NET development environment. This technology maps objects to SQL-based relational table structures, allowing operations on table data as objects. Object instantiation enables functions like querying, adding, deleting, and updating table data through object methods, thus avoiding excessive and cumbersome SQL statements and improving the efficiency of data interaction in the 3D design system. The usage is as follows: First, establish the database relational tables. Define corresponding shell objects based on the database tables. Then, create interrelated mapping files by combining the relational tables and object persistent classes. Finally, connect to and access the database and database tables through configuration files in the app and web applications. Define object operation functions in the application program to implement CRUD operations on the database tables. The complex SQL statements and database access interface details are encapsulated within the NHibernate framework. During development, only the database tables, object persistent classes, and corresponding mapping files need to be considered, allowing for the storage of large numbers of database tables and improved system efficiency.
[0064] Furthermore, starting from the construction of 3D model data, and combining NHibernate technology for data storage management, the underground cave system functions were developed around Skyline's powerful interface service system, which well met the application needs in engineering practice. The camera components formed a cave path roaming function and a fixed-point panoramic view function, providing a good reference for observing underground engineering. At the same time, a large amount of monitoring data storage and 2D linkage query module were integrated, providing workers with an integrated information management system for 3D underground cave loading and display, data storage and query, improving the practicality of the design platform.
[0065] Example 3:
[0066] Based on Example 2, the location of the measuring point inside the cave is referred to as the monitoring section. The measurement data of the monitoring section is transmitted to the data processing module, which uses a judgment system to make a preliminary judgment on the data.
[0067] The ultimate relative displacement value X0 refers to the percentage of the maximum subsidence of the arch within the tunnel relative to the tunnel height, or the percentage of the maximum change in horizontal clearance relative to the tunnel excavation width. The ultimate relative displacement value is mainly used to determine the reliability of measurement data, the stability of initial support, and the end time of monitoring measurements.
[0068] The allowable relative displacement value refers to the allowable relative displacement value of the initial support of the tunnel, which is based on the distance of the measuring point from the excavation face and is obtained through the limit relative displacement of the initial support.
[0069] The span of the cavern is B;
[0070] The judgment is expressed as:
[0071] Allowable relative displacement value: X 1B =65%X0;X 2B =90%X0;X nB =100%X 0; ;
[0072] X represents the measured displacement value:
[0073] When X≦X 1B / 3 or X≦X 2B At 3:00, reduce the monitoring frequency and continue construction;
[0074] When X 1B / 3≦X≦2X 1B / 3 or X 2B / 3≦X≦X 2B At 3 o'clock, increase the monitoring frequency and strengthen support measures;
[0075] When X≧2X 1B / 3 or X ≥ 2X 2B At 3:00, increase monitoring frequency and suspend construction.
[0076] The transmission module also includes a local area network and a wireless transmission device. All the measuring points of every 5 monitoring sections are connected to one wireless transmission device. The data processing module is equipped with a data receiving device for every 5 wireless transmission devices. The wireless transmission device sends data to the data receiving device through the local area network, and the data receiving device sends the data to the data processing module through wired transmission.
[0077] Specifically, one of the characteristics of this judgment method is its emphasis on on-site monitoring and measurement. It allows for a certain degree of deformation in the surrounding rock while preventing excessive deformation, and utilizes the test results to promptly supplement the design and guide construction. It helps to understand the dynamics of the surrounding rock, the stress state of the support structure under different conditions, and makes a preliminary assessment of the stability of the rock strata during subsequent tunnel excavation. Furthermore, it can verify the rationality of the support structure type and parameters, and evaluate the rationality and safety of the support structure and construction methods. Moreover, it can optimize the construction organization design, providing a scientific basis and technical guarantee for saving project investment and improving the design and construction level of tunnels by using a design platform.
[0078] Furthermore, the first monitoring module collects excavation data within the tunnel and feeds it back to the data processing module. After modeling using the 3D design system on the design platform, the tunnel is excavated further to expand the cavern into a secondary structure. Subsequently, a measuring point is set up at every span, and the second monitoring module monitors the monitoring section of the cavern, completing the collection of stability data after excavation, which is beneficial for more effective excavation ahead. Moreover, as the cavern is excavated and its length increases, the distance from which the second monitoring module sends data to the data processing module at the cavern entrance also increases. Wired transmission signals are stable, but are easily affected by transmission distance; wireless transmission signals are not as stable as wired transmission signals, but are less affected by factors related to transmission distance than wired transmission.
[0079] Therefore, through the coordination of wireless transmission devices, data receiving devices, and local area networks (LANs), for example: five second monitoring modules form a monitoring section, and the five monitoring sections are connected to one wireless transmission device. These five monitoring sections transmit data to one wireless transmission device via wired transmission. Then, the five wireless transmission devices, as a group, transmit the data wirelessly to one data receiving device via the LAN. The data receiving device then transmits the data to the data processing module via wired transmission. That is, the data is transmitted to the data processing module through a combination of wired-wireless-wired transmission. The monitoring section is close to the construction site and is easily affected by excavation and other factors, so wired transmission is used to improve the stability of data transmission. The distance between the monitoring section and the data processing module is far from the construction site, so wireless transmission is used to avoid data packet loss caused by long-distance wired transmission, thereby improving the stability of data transmission. The area near the data processing module is close to the cave entrance and has many electrical and other equipment, so switching to wired transmission further improves the stability of data transmission, thereby improving the accuracy of data received by the 3D design system and making it more conducive to the use of the design platform.
[0080] Example 4:
[0081] Based on Embodiment 3, as shown in the accompanying drawings of the specification. Figures 2-4As shown, the construction monitoring unit includes a measuring device, and a second monitoring module is installed inside the measuring device. The measuring device is used for the monitoring work of the second monitoring module.
[0082] The measuring device includes a pressure box 1, which is located inside the concrete. The middle part of the pressure box 1 is made of an elastic material, such as rubber, while the two ends of the pressure box 1 are made of a hard material, such as metal. A spring is installed inside the pressure box 1, and a sensor 11 is installed at the center of the pressure box 1. The two ends of the sensor 11 contact the inner walls of the two ends of the pressure box 1. The sensor 11 is conventionally used to monitor the force generated by the shrinkage of the concrete wall after the cavern wall has solidified or the stress of the concrete itself, so as to avoid the situation where the concrete wall has hidden cracks that cannot be detected by workers in time.
[0083] The pressure box 1 has an embedded pipe 12 on one side of its elastic material. One end of the embedded pipe 12 is located inside the concrete, and the other end is located outside the concrete. The embedded pipe 12 is fixed by the concrete. The embedded pipe 12 is tapered and has a larger diameter end facing the inside of the pressure box 1. The inside of the embedded pipe 12 is connected to the inside of the pressure box 1. The embedded pipe 12 faces the power replacement part of the sensor 11. An installation rod 13 is slidably connected inside the embedded pipe 12. The installation rod 13 is connected to the embedded pipe 12 through a vibration damper. A camera assembly 14 and a displacement detector 15 are installed at one end of the installation rod 13. The camera assembly 14 is used for video monitoring of the tunnel construction, and the displacement detector 15 is used to detect cross-sectional deformation displacement.
[0084] A rotating plate 16 is provided near the mounting rod 13 on the pre-embedded pipe 12, and a sliding box 2 is rotatably connected to the rotating plate 16. The sliding box 2 rotates around the rotating plate 16 in a circle, and an electromagnet 21 is provided between the sliding box 2 and the rotating plate 16. A detection rod 22 is provided inside the sliding box 2, with one part of the detection rod 22 located inside the sliding box 2 and the other part located outside the top of the sliding box 2. The end of the detection rod 22 inside the sliding box 2 is spherical, and the surface of the spherical shape is provided with a rubber layer. The detection rod 22 contacts the sliding box 2 through the rubber layer. A rotating ball 23 is provided inside the sliding box 2, and the rotating ball 23 contacts the spherical end of the detection rod 22. The surface of the rotating ball 23 is provided with a rubber layer. The rotating ball 23 contacts the detection rod 22 through two layers of rubber. The electromagnet 21 contacts the bottom of the rotating ball 23 without a rubber layer. When the electromagnet 21 is energized, it fixes the rotating ball 23, the sliding box 2, and the rotating plate 16. The detection rod 22 is a conventional rod with telescopic function, and a detection device is installed at the end of the detection rod 22 away from the sliding box 2.
[0085] Specific workflow: During the pouring of the concrete wall of the cavern, the pressure box 1 and the pre-embedded pipe 12 near the pressure box 1 are fixed in the concrete layer using conventional methods, so that the pre-embedded pipe 12, which is far from the pressure box 1 in the entire measuring device, is located outside the cavern wall. When the concrete shrinks, it squeezes the pressure box 1, and the two ends of the pressure box 1 are squeezed and contracted towards the middle. The sensor 11 inside the pressure box 1 detects the pressure change and uploads it, achieving the purpose of real-time monitoring. At the same time, the pressure box 1 acts as a shield for the sensor 11, preventing the concrete from contacting the sensor 11 for a long time and causing corrosion, damage, etc., thus increasing the protection of the sensor 11 and improving the stability of monitoring. In addition, rubber and conventional metals are inexpensive and suitable for mass installation. Moreover, the measuring device is installed during the pouring process, avoiding the need for a large number of holes after pouring, which would affect the stability and support of the cavern wall. A large number of holes would also affect the already installed second monitoring module or the transmission of data.
[0086] By setting up the pre-embedded pipe 12, when the sensor 11 is without power, the mounting rod 13 and the conventionally used vibration damper can be removed. Workers can use tweezers and other tools to insert into the pressure box 1 through the tapered tube 12 and replace the power supply in the sensor 11 without damage, extending the monitoring time and improving the ease of use of the measuring device, thereby improving the practicality of the design platform. When the camera component 14 and displacement detector 15 monitor for a long time on the mounting rod 13, they can filter out the minor vibrations generated during construction through the vibration damper, improving the stability of monitoring and the accuracy of monitoring data. This allows the measuring device to filter out invalid data generated by minor vibrations through the vibration damper, improving the working efficiency of the design platform.
[0087] When rock strata need to be inspected, inspection is performed using a detection device, such as a conventional lidar device for rock inspection. A small number of rotating plates 16 and other components can be installed at each monitoring section to avoid overlapping monitoring ranges. The inspection method is as follows: the sliding box 2 rotates along the center of the rotating plate 16, causing the detection rod 22 to rotate. After the sliding box 2 rotates to the designated position and remains stationary, the detection rod 22 begins to swing. The detection rod 22 rotates at the top of the sliding box 2, and the spherical part of the detection rod 22 rotates, causing the rotating ball 23 to rotate. The two are transmitted through contact via a rubber layer until the detection rod 22 swings to the position reached by the inspection device. At a designated location, a conventional electromagnet 21 is powered by an external power source. The parts of the detection device located away from the electromagnet 21 are magnetically shielded to prevent the switching on and off of the electromagnet 21 from affecting the entire detection device. When the electromagnet 21 is energized, it generates magnetic attraction, fixing the rotating ball 23, the sliding box 2, and the rotating plate 16 together. The frictional force generated by the rubber contact between the rotating ball 23 and the spherical part of the detection rod 22 fixes the detection rod 22 in place. This allows the detection device to be fixed in any position for an extended period, facilitating detection and the collection of rock strata data, and improving the accuracy of the collected data.
[0088] Furthermore, since the bottom of the spherical part of the detection rod 22 contacts the rotating ball 23 through rubber, and the top also contacts the top of the sliding box 2 through rubber, the detection rod 22 makes flexible contact with the sliding box 2 through rubber. Rubber also has a good vibration damping effect, so when the embedded pipe 12 vibrates due to construction vibration, the detection rod 22 dampens the vibration through rubber, improving the stability of the detection device when collecting data, further improving the accuracy of the collected data, thereby improving the data accuracy of the second monitoring module, and thus improving the practicality of the design platform. Even in the later stages of tunnel excavation, the tunnel walls poured in the early stages of excavation no longer require monitoring by the design platform. Workers can also disassemble the removable parts inside the measuring device, leaving the pressure box 1 and the embedded pipe 12 in the tunnel wall, saving costs. Furthermore, workers can add concrete to the embedded pipe 12, filling the embedded pipe and pressure box to increase support, thereby improving the integrity of the tunnel wall, enhancing the support of the tunnel wall, and thus improving the practicality of the design platform.
