The construction monitoring unit collects measurement values ​​during tunnel construction and optimizes design details. It is characterized in that the construction monitoring unit includes:

[0044] A mobile module, the mobile module is used to move in the cave after excavation;

[0049] Specifically: The cavern is constructed by conventional excavation. When geological conditions and other conditions meet the excavation requirements, the design platform is designed to directly carry out the excavation of the cavern in one step. First, advance support should be applied to the cavern, which requires full use of the steel frame erected in the previous cycle, that is, mechanical excavation is first performed, and 8cm thick concrete is sprayed on it to seal the face, and 4cm thick concrete is initially sprayed as initial and temporary support, and a temporary steel frame is erected on it; after drilling and setting the system anchor, concrete is sprayed again to make the construction reach the designed thickness; when the geological conditions are not ideal, the design platform first excavates a tunnel with small space and easy to excavate; then the mobile module drives the first monitoring module into the tunnel to conduct on-site inspection of the rock formation and water leakage in the tunnel; then the first monitoring module transmits the collected data to the data sorting module through wired transmission, and the design platform analyzes and sorts the data collected by the first monitoring module as data support for the subsequent secondary shaping of the tunnel expansion cavern, so that the design platform adopts different construction methods and measures for the excavation of the cavern in one step and the secondary shaping, which improves the convenience of use;

The calculation formula is the calculation formula for the conventional engineering survey line layout: the calculation formula for the layout of the triangular survey line network, combined with the monitoring during the construction of the above-mentioned secondary molding cavern, provides a basis for the back calculation of relevant parameters of the underground structure and the correct layout of the survey line network; the so-called independent survey line network refers to a group of survey lines that can uniquely determine the displacement value of each measuring point after excluding the rigid body displacement; that is, using a group of survey lines arranged by an independent survey line network to measure the relative displacement between the measuring points, the displacement of each measuring point can be uniquely determined, the data collection and transmission efficiency of the cavern construction is improved, the real-time monitoring is improved, and the design platform can provide effective guarantee for cavern excavation;

[0051] Moreover, through the mutual coordination of the first monitoring module, the second monitoring module and the special measuring line network layout, the accuracy analysis of the construction dynamic monitoring data can make the layout distribution of the monitoring measuring points and measuring lines more reasonable and reduce bad points and invalid data under the conditions of the same measuring points, measuring equipment and personnel; at the same time, since the accuracy of the measured data is improved, the accuracy of the inverse analysis results is improved, and the basic mechanical parameters obtained by inverse deduction are more accurate and reasonable, laying a good foundation for the numerical calculation of the surrounding rock and supporting structure of the cavern.

[0052] Embodiment 2:

[0053] On the basis of the first embodiment, the data sorting module adopts a three-dimensional design system based on the Skyline platform. The design platform collects data of the cave after excavation through the first monitoring module and sends it to the data sorting module; the continued excavation and construction reinforcement of the cave are changed accordingly according to the data of the first monitoring module; the second monitoring module performs long-term monitoring of the cave after construction reinforcement, and provides data reference for the early excavation design of the cave, the mid-term cave reinforcement design and the later electromechanical design distribution;

[0054] The design process of the 3D design system is:

[0055] Based on the data uploaded by the first monitoring module and the data of the previous cavern information modeling, it is constructed through 3D Max and converted into Skyline's unique lightweight xpl2 data format. It is loaded into the FLY project file through the 3DModel command, and finally the parameters and properties of the model are set to adjust the cavern excavation position, direction, and size and shape of the expansion;

[0056] The FLY project file is generated by TerraExplorer pro and is an index file of three-dimensional data, which contains network space and data address, that is, the data parameters of MPT three-dimensional terrain data address, point data address, model data address, two-dimensional plane map address, and image data address are integrated into a FLY project file, and the display of three-dimensional data, data information tree directory, and information tree display of two-dimensional navigation map are realized through the loading of 3DModel command; after clicking the subnode in the information tree, the unique object three-dimensional positioning fly-in display effect is realized on the Skyline platform;

[0057] The system framework of the 3D design system is designed as a 3-layer structure, namely: presentation layer, middle layer and data layer; the presentation layer is the client system operation interface layer, which implements corresponding functions through user commands; the middle layer provides services for data transmission and Skyline function interface; the data layer uses the database of the cave collection and sorting library at the data sorting module end to store and manage data for extraction by the 3D design system;

[0058] In the three-dimensional design system,

[0059] Design of presentation layer: Use the development tools of visual integrated environment, adopt Java language to develop Web engineering projects, use JavaScript script to call the function in Skyline for secondary development; its page layout adopts the layout of web page and combines with hyperlink framework for layout optimization design;

[0060] Design of the middle layer: Use TerraExplorer Pro secondary development function library to build a 3D data system platform; provide powerful 3D space auxiliary decision support and analysis functions for underground engineering;

[0061] Design of the data layer: Data is stored in the server in the form of FLY files with permission encryption. According to the characteristics of the cavern project, a large amount of excavation construction data information needs to be stored and queried. Therefore, the attribute data of a large amount of spatial objects is stored in the shared PTZ database using storage technology.

[0062] Specifically: Skyline platform mainly consists of three components: TerraBuilder, TerraExplorer, and TerraGate; TerraBuilder is responsible for the construction of 3D terrain model data and spatial object model data; TerraExplorer is mainly responsible for the implementation of 3D data operation and analysis functions; TerraGate is the release of a 2D data sharing platform on the server side, and client users can log in to access the database through the Internet; Skyline supports development in multiple languages ​​and provides a rich API interface, which can not only realize the creation and management of 3D data browsing operations, information trees, layers, objects, etc., but also includes a database extension module to achieve connection with other databases and perform data storage, query and update operations. It has the ability to accommodate massive data, avoid problems with massive monitoring data storage during large-scale cavern construction, improve the stability of monitoring data storage and extraction, and facilitate the development of the design platform during cavern construction;

[0063] The storage technology uses Nhibernate storage technology, which is an object-relational database mapping tool for NET development environment. Object-relational mapping technology can be used to correspond objects to SQL-based relational table structures, and table data can be used as objects to operate and develop object instantiation, that is, to implement table data query, addition, deletion, and update functions through object methods, thereby avoiding too many cumbersome SQL statements, improving the efficiency of data interaction in the database of the three-dimensional design system, and improving the efficiency of use; the method of use is: first establish a database relational table, define the corresponding shell object according to the database table, create a mutually related mapping file by combining the relational table and the object persistence class, and then connect to access the database and database table through configuration files such as app and web; define the object operation function in the application program to implement the addition, deletion, and modification of database table data. The cumbersome SQL statements and database access interface details are encapsulated in the Nhibernate framework. In the development and utilization process, you only need to pay attention to the database table, object persistence class and the corresponding mapping file to store a large number of database tables and improve the operation efficiency of the system;

[0064] Furthermore, starting from the construction of 3D model data, combined with NHibernate technology for data storage management, and centering on Skyline's powerful interface service system, the underground cave system function is developed to meet the application needs in engineering practice. The camera components form the path roaming function and the fixed-point surround function in the cave, which provides a good reference for observing underground projects. At the same time, a large number of monitoring data storage and two-dimensional linkage query modules are integrated to provide workers with an information management system that integrates 3D underground cave loading display, data storage and query, thereby improving the practicability of the design platform.

[0065] Embodiment three:

[0066] On the basis of the second embodiment, the position where the measuring point is located in the cave is called the monitoring section, and the measurement data of the monitoring section is transmitted to the data sorting module, and the data sorting module uses the determination system to make a preliminary determination on the data;

[0067] The limit relative displacement value X0 refers to the percentage of the maximum value of the vault sinking in the cavern relative to the cavern height, or the percentage of the maximum value of the horizontal clearance change relative to the cavern excavation width; the limit relative displacement value is mainly used to judge the reliability of the measurement data, determine the stability of the initial support, and judge the end time of the monitoring measurement;

[0068] The allowable relative displacement value refers to the relative displacement value allowed for the initial support of the tunnel according to the distance between the measuring point and the excavation surface, and the value of the initial support limit relative displacement;

[0069] The span value 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 is the measured displacement value:

[0073] When X ≦ X 1B / 3 or X≦X 2B / 3, reduce the monitoring frequency and continue construction;

[0074] When X 1B / 3≦X≦2X 1B / 3 or X 2B / 3≦X≦X 2B / 3, increase monitoring frequency and strengthen support measures;

[0075] When X≧2X 1B / 3 or X≧2X 2B / 3:00, increase monitoring frequency and suspend construction;

[0076] The transmission module also includes a local area network and a wireless transmission device, and all the measuring points of every five monitoring sections are connected to one wireless transmission device; a data receiving device is provided near each of the five wireless transmission devices in the data sorting module, and 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 sorting module through wired transmission;

[0077] Specifically: One of the characteristics of this determination method is that it focuses on on-site monitoring and measurement, which allows the surrounding rock to have a certain deformation, prevents the surrounding rock from having excessive deformation, and uses the test results to supplement the design and guide the construction in a timely manner; grasps the dynamics of the surrounding rock, understands the stress state of the support structure under different circumstances, and makes a preliminary evaluation of the stability of the rock formation during subsequent cave excavation; and can also verify the rationality of the support structure type and support parameters, and evaluate the rationality and safety of the support structure and construction methods; and can also optimize the construction organization design, provide a scientific basis and technical guarantee for saving engineering investment using the design platform, and improve the design and construction level of the cave;

[0078] Furthermore, the first monitoring module collects cave excavation data in the tunnel and feeds it back to the data sorting module. After modeling by the three-dimensional design system in the design platform, the tunnel is excavated forward to expand the cave for secondary molding. Subsequently, a measuring point is set every other span, and the monitoring section of the cave is monitored by the second monitoring module to complete the collection of cave stability data after excavation, which is conducive to more effective excavation ahead. Moreover, as the cave is excavated, the length of the cave increases, and the distance from which the second monitoring module sends data to the data sorting module at the cave entrance increases accordingly. Wired transmission signals are stable, but are easily affected by transmission distance. Wireless transmission signals are not as stable as transmission signals, but are less affected by transmission distance than wired transmission.

[0079] Therefore, through the cooperation of wireless transmission devices, data receiving devices and local area networks, for example: 5 second monitoring modules form a monitoring section, and 5 monitoring sections are connected to a wireless transmission device. These 5 monitoring sections transmit data to a wireless transmission device through wired transmission, and then the 5 wireless transmission devices form a group to wirelessly transmit the data to a data receiving device through the local area network, and then the data receiving device transmits the data to the data sorting module through a wired method, that is, the data is transmitted to the data sorting module through a combination of wired-wireless-wired; the monitoring section is close to the construction site and is easily affected by various situations such as excavation. Wired transmission is used to improve the stability of data transmission; the distance between the monitoring section and the data sorting module is far away from the construction. Wireless transmission is used to avoid data packet loss caused by long-distance wired transmission, thereby improving the stability of data transmission; the place close to the data sorting module is close to the cave entrance, and many electrical appliances and other equipment are installed, so it is switched to wired transmission to further improve the stability of data transmission, thereby improving the accuracy of data received by the three-dimensional design system, which is more conducive to the use of the design platform.

[0080] Embodiment 4:

[0081] Based on the third embodiment, as shown in the accompanying drawings of the specification Figure 2-Figure 4As shown, the construction monitoring unit includes a measuring device, in which a second monitoring module is installed, and the measuring device is used for monitoring the second monitoring module;

[0082] The measuring device comprises a pressure box 1, which is located in the concrete. The middle part of the pressure box 1 is made of elastic material, such as rubber, and the two ends of the pressure box 1 are made of hard material, such as metal. A spring is arranged in the pressure box 1, and a sensor 11 is arranged 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 contraction of the concrete wall surface after solidification of the cavern or the stress of the concrete itself, so as to avoid the occurrence of hidden cracks in the concrete wall surface, which cannot be discovered by workers in time.

[0083] A pre-buried pipe 12 is provided on one side of the elastic material of the pressure box 1, one end of the pre-buried pipe 12 is located in the concrete, and the other end is located outside the concrete. The pre-buried pipe 12 is fixed by the concrete. The pre-buried pipe 12 is a conical tube, and the end with a larger diameter of the pre-buried pipe 12 faces the inside of the pressure box 1, and the inside of the pre-buried pipe 12 is connected with the inside of the pressure box 1, and the pre-buried pipe 12 faces the power supply replacement part of the sensor 11; a mounting rod 13 is slidably connected in the pre-buried pipe 12, and the mounting rod 13 is connected to the pre-buried pipe 12 through a shock absorber, and a camera assembly 14 and a displacement detector 15 are installed at one end of the mounting rod 13, the camera assembly 14 is used for video monitoring of the tunnel construction, and the displacement detector 15 is used to detect the cross-sectional deformation displacement;

[0084] The embedded pipe 12 is provided with a rotating plate 16 at a position close to the mounting rod 13, and a sliding box 2 is rotatably connected to the rotating plate 16, and the sliding box 2 rotates in a circle around the rotating plate 16, and an electromagnet 21 is provided between the sliding box 2 and the rotating plate 16; a detection rod 22 is provided in the sliding box 2, and a part of the detection rod 22 is located in the sliding box 2, and the other part is located outside the top of the sliding box 2, and the end of the detection rod 22 located in the sliding box 2 is spherical, and a rubber layer is provided on the spherical surface, and the detection rod 22 contacts the sliding box 2 through the rubber layer; a rotating ball 23 is provided in the sliding box 2, and the rotating ball 23 contacts the spherical end of the detection rod 22, and a rubber layer is provided on the surface of the rotating ball 23, and the rotating ball 23 contacts the detection rod 22 through two layers of rubber layers, and the electromagnet 21 contacts the bottom of the rotating ball 23 without the rubber layer, and the electromagnet 21 is energized to fix the rotating ball 23, the sliding box 2 and the rotating plate 16; the detection rod 22 is a conventional rod with a telescopic function, and a detection device is installed at the end of the detection rod 22 away from the sliding box 2;

[0085] Specific work flow: when pouring the concrete wall of the cavern, the pressure box 1 and the embedded pipe 12 close to the pressure box 1 are fixed in the concrete layer in a conventional manner, so that the embedded pipe 12 far away from the pressure box 1 in the entire measuring device is located outside the cavern wall; when the concrete shrinks, the pressure box 1 is squeezed, and the two ends of the pressure box 1 are squeezed and contracted toward the middle, and the sensor 11 in the pressure box 1 monitors the pressure change and uploads it, so as to achieve the purpose of real-time monitoring. At the same time, the pressure box 1 blocks the concrete for the sensor 11 to avoid corrosion and crushing caused by long-term contact of the concrete with the sensor 11, thereby increasing the protection of the sensor 11 and improving the monitoring stability; in addition, rubber and conventional metals are low in price and suitable for large-scale placement and installation; in addition, the measuring device is installed during the pouring process to avoid a large number of holes after pouring, which affects the stability and support of the cavern wall, and a large number of holes will also affect the installed second monitoring module or data transmission;

[0086] By setting the embedded pipe 12, when the sensor 11 is out of power, the mounting rod 13 and the conventionally used shock absorber can be removed, and the worker can use tweezers and other tools to reach into the pressure box 1 through the conical tubular embedded pipe 12, and replace the power supply in the sensor 11 without damage, thereby extending the monitoring time and improving the convenience of using the measuring device, thereby improving the practicality of the design platform; when the camera assembly 14 and the displacement detector 15 are monitored on the mounting rod 13 for a long time, the shock absorber can filter the tiny vibrations generated by the construction, improve the stability of the monitoring and the accuracy of the monitoring data, so that the measuring device can filter the invalid data generated by the tiny vibrations through the shock absorber, and improve the working efficiency of the design platform;

[0087] When it is necessary to detect the rock formation, the detection is carried out by using a detection device, such as a conventional laser radar device for detecting rocks; a small number of parts such as rotating plates 16 can be set at each monitoring section to avoid overlapping monitoring ranges; the detection method is as follows: the slide box 2 is rotated along the center of the rotating plate 16 to drive the detection rod 22 to rotate, the slide box 2 is rotated to the specified position and then stands still, and the detection rod 22 begins to swing; the detection rod 22 rotates at the top of the slide box 2, and the spherical part of the detection rod 22 rotates to drive the rotating ball 23 to rotate, and the two are in contact with each other through the rubber layer for transmission; until the detection rod 22 swings to the detection device reaches At a designated position, a conventional electromagnet 21 is powered by an external power supply, and a portion of the detection device that is far from the electromagnet 21 is subjected to magnetic isolation treatment to prevent the on and off of the electromagnet 21 from affecting the entire detection device; the electromagnet 21 is energized to generate magnetic attraction, which fixes the rotating ball 23, the slide box 2 and the rotating plate 16, and the friction force generated by the contact between the rotating ball 23 and the spherical portion of the detection rod 22 through the rubber fixes the detection rod 22, so that the detection device can be fixed at any position for a long time, which is convenient for detection and rock formation data collection, and improves the accuracy of 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 slide box 2 through rubber, the detection rod 22 is in flexible contact with the slide box 2 through rubber, and rubber has a good vibration reduction effect, so that when the embedded pipe 12 vibrates due to the influence of construction vibration, the detection rod 22 reduces vibration through the rubber, thereby 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 further improving the practicality of the design platform; even in the later stage of cave excavation, the cave wall poured in the early stage of excavation no longer needs to be monitored by the design platform, and the workers can also remember to disassemble the detachable parts in the measuring device, leaving the pressure box 1 and the embedded pipe 12 in the cave wall, saving costs; and, the workers can also add concrete to the embedded pipe 12, fill the embedded pipe and the pressure box, increase the support, thereby supplementing the integrity of the cave wall, improving the support of the cave wall, and further improving the practicality of the design platform.
