DETAILED DESCRIPTION

[0039] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0040] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and cannot be understood as limiting the specific scope of protection of the present application.

[0041] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0042] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0043] One of the preferred embodiments of the present application is as follows: Figure 1 As shown, a micro-disturbance in-situ geological multi-parameter intelligent monitoring device includes a driving mechanism 2, a multi-section modular protection tube 1, a benchmark 3 and a plurality of monitoring modules. Any two sections of the protection tube 1 can be detachably fixedly connected, so that when installing the monitoring device of the present application, the number of protection tubes 1 required can be selected according to the depth of the mark hole reserved on the ground; then, the corresponding number of protection tubes 1 are inserted into the mark hole under the drive of the driving mechanism 2 installed on the ground; and in the process of insertion, each time a section of the protection tube 1 is inserted, another section of the protection tube 1 can be detachably fixedly connected with the inserted protection tube 1, and the protection tubes 1 are connected and inserted in sequence until all the protection tubes 1 are inserted into the mark hole and connected to form a whole, so that the protection holes 120 in the center of all the protection tubes 1 can be connected and aligned with each other. Therefore, when installing the benchmark 3, it can be inserted into the bottom of the mark hole along the protection hole 120 for geological settlement monitoring. Multiple monitoring modules are correspondingly installed on each protection tube 1, and can be opened when each protection tube 1 is inserted into the set installation position, so as to ensure the stability of the protection of the benchmark 3 and the accuracy of the monitoring data of the benchmark 3. At the same time, during the opening of the protection tube 1, the correspondingly installed monitoring module can be inserted into the soil at the side of the marking hole as the protection tube 1 is opened, so as to realize the fluidity monitoring of the soil; and multiple monitoring modules can monitor the soil at different depths of the marking hole to ensure the monitoring accuracy and monitoring range of the data.

[0044] It should be known that when monitoring the geological settlement of soil, it is necessary to first drill a mark hole of corresponding depth on the ground. The specific depth of the mark hole can be selected according to the specific geological conditions, generally between 15m and 20m. After the drilling of the mark hole is completed, a protective structure needs to be set up to protect the soil on the side of the mark hole to avoid the interference of the soil flow on the benchmark 3 during the continuous monitoring process, which leads to inaccurate data of geological settlement monitoring. The setting of the protective structure of traditional geological settlement monitoring generally adopts an expansion structure, that is, after the protective structure is installed at the set position, the expansion structure is opened on the ground by the corresponding pull rope, so that the expansion structure expands to the side of the mark hole. However, the mark hole does not necessarily present a regular circular structure after the drilling is completed, which makes the expansion structure cause the protective structure to tilt to a certain extent during the expansion process; and for softer soil areas, the expansion structure and the soil on the side of the mark hole may not provide sufficient support to meet the stable support of the protective structure.

[0045] In the present embodiment, after the protection tube 1 is installed at the set position, it can be opened so that the corresponding support structure can be inserted into the soil; that is, the overall radial dimension of the protection tube 1 will be significantly increased, so that a larger contact area can be formed with the soil to provide sufficient support force to ensure the installation stability of the protection tube 1, thereby effectively avoiding interference between the protection hole 120 in the center of the protection tube 1 and the benchmark 3 to ensure the accuracy of the monitoring data of the geological subsidence by the benchmark 3.

[0046] Since the protection of the marking hole by the protective tube 1 needs to be inserted into the soil through a supporting structure, the corresponding monitoring module can be installed on the supporting structure of the protective tube 1, so that when the supporting structure is inserted into the soil, the monitoring module can be inserted together. This ensures that the protective tube 1 can achieve stable protection of the marking hole while also monitoring the fluidity of the soil on the side of the marking hole through the monitoring module. And since the protective tube 1 has multiple sections, a monitoring module can be installed on each section of the protective tube 1, and then the soil at different depths of the marking hole can be monitored through multiple monitoring modules. There are multiple sets of monitoring modules corresponding to each section of the protective tube 1, so that the accuracy of monitoring can be ensured by monitoring data in different directions through multiple monitoring modules at the same depth. Of course, the monitoring module can also detect other parameters of the soil.

[0047] When the soil data is monitored by the monitoring module, since the environment in the marking hole is a humid environment, long-term data monitoring may cause damage to the monitoring module or other related structures. If the protective tube 1 adopts an integral structure, it is necessary to pull out all the protective tubes 1 from the marking hole and disassemble them completely to complete the repair of the fault. In this embodiment, it is only necessary to locate the specific fault position according to the abnormal data of the monitoring module, and then pull the protective tube 1 out of the marking hole through the driving mechanism 2 until the protective tube 1 corresponding to the fault position is exposed to the ground. At this time, it is only necessary to replace the protective tube 1 at the fault position with a new protective tube 1, and then re-insert the disassembled non-faulty protective tube 1 into the marking hole under the drive of the driving mechanism 2. Compared with the integral structure, the multi-section modular protective tube 1 of this embodiment can effectively reduce the difficulty of fault maintenance and improve the efficiency of fault maintenance. Specifically, it can be assumed that the protective tube 1 has fifteen sections, and the fault position is located at the fifth section from top to bottom. Then the driving mechanism 2 only needs to lift the protective tube 1 up by five sections to disassemble and replace the faulty protective tube 1.

[0048] It should also be known that the specific length of each section of the protection tube 1 can be selected according to the actual needs of those skilled in the art; the length of the protection tube 1 can be uniform or non-uniform, so as to facilitate fine-tuning the installation of the protection tube 1 according to the depth of the marked hole. Generally speaking, the specific length of the protection tube 1 is between 50 cm and 150 cm.

[0049] In this embodiment, the protective tube 1 has a variety of specific structures. For ease of understanding, one of the specific structures will be described in detail below. Figures 2 to 4 , Fig. 9 and Fig.11 As shown, the protective tube 1 includes an outer tube 11, an inner tube 12 and at least one group of plug plates 13. Adjacent protective tubes 1 can be detachably fixedly connected through the outer tube 11, and when the connection of adjacent protective tubes 1 is completed, the inner tubes 12 between adjacent protective tubes 1 can be plugged in so as to rotate synchronously. The inner tube 12 is rotatably mounted inside the outer tube 11, and the protective hole 120 is arranged at the center of the inner tube 12. Multiple groups of plug plates 13 can be arranged at intervals along the axial direction of the outer tube 11, and multiple plug plates 13 of each group can be arranged in the area between the outer tube 11 and the inner tube 12 along the circumferential direction of the outer tube 11. The plug plates 13 can be guided and matched with the outer tube 11, and the plug plates 13 can be pulled and matched with the inner tube 12, and the monitoring module is installed on the plug plates 13. Therefore, when all the protective tubes 1 are inserted to the set positions of the marking holes, the inner tube 12 of the topmost protective tube 1 can be rotated on the ground to drive all the inner tubes 12 to rotate relative to the outer tube 11, and then all the plug plates 13 of each section of the protective tube 1 carrying the monitoring module can be driven to extend out of the corresponding outer tube 11 to be inserted into the soil at different depths of the marking hole.

[0050] It should be known that the number of groups of plug plates 13 corresponding to each section of the protection tube 1 and the specific number of each group of plug plates 13 can be set according to the actual needs of those skilled in the art; for example Figure 4 As shown, each section of the protection tube 1 corresponds to a group of plug plates 13 , and a group of plug plates 13 has six plug plates; the group of plug plates 13 can be arranged in the middle area of ​​the protection tube 1 .

[0051] It is understandable that there are many specific ways to detachably connect adjacent protection tubes 1 through the outer tube 11; one specific example is as follows: Figure 2 and Figure 3As shown, the upper and lower ends of a single outer tube 11 are respectively provided with a connection block 112 and a connection groove 113, the sizes and positions of the connection block 112 and the connection groove 113 are mutually corresponding, and the number of the connection block 112 and the connection groove 113 is provided in multiples, such as three or four; the multiple connection blocks 112 and the connection groove 113 can be arranged at equal intervals along the circumferential direction of the outer tube 11. Therefore, when connecting adjacent protective tubes 1, the connection block 112 at the upper end of the lower protective tube 1 can be correspondingly inserted into the connection groove 113 at the lower end of the upper protective tube 1, and then the pin shaft simultaneously penetrates the plugged connection block 112 and the connection groove 113 along the radial direction of the outer tube 11, so that a detachable fixed connection is formed between the two adjacent protective tubes 1. When disassembly is required, it is only necessary to pull out the pin shaft; of course, in order to ensure stable connection, the two protective tubes 1 can also be detachably connected by threading the screw rod and the screw hole penetrating the connection block 112 and the connection groove 113 to achieve a detachable connection.

[0052] It is also understandable that there are many ways to rotatably connect adjacent inner tubes 12 to each other. A specific example is as follows: Figure 4 and Figure 7 As shown, the upper end of the inner tube 12 is a plug connector 123 with a non-circular cross section, and the lower end of the inner tube 12 is a plug slot 124 with a non-circular cross section and adapted to the plug connector 123. There are many common specific shapes of non-circular cross sections, such as ellipse and polygon, etc. In this embodiment, the plug connector 123 and the plug slot 124 with a regular hexagonal cross section are preferably used. Therefore, when two adjacent protective tubes 1 are connected, the inner tubes 12 corresponding to the two adjacent protective tubes 1 will be plugged into the plug slot 124 of the other inner tube 12 through the plug connector 123 of one inner tube 12 respectively; and then when the inner tube 12 located at the top of the ground rotates, the plug connector 123 and the plug slot 124 can drive all the inner tubes 12 to rotate relative to the outer tube 11. In the process of the inner tube 12 rotating relative to the outer tube 11, all the outer tubes 11 can be restricted to be stationary by the driving mechanism 2, or the outer tube 11 located at the top of the ground can be restricted to be stationary in other ways.

[0053] In this embodiment, Figure 5 , Figure 8 , Fig. 9 and Fig.11As shown, a plurality of arc-shaped baffles 116 are arranged equidistantly in the middle of the outer tube 11 along the circumferential direction. The specific number of baffles 116 corresponds to the number of plug-ins 13 in each group. For example, if the number of plug-ins 13 is six, the number of baffles 116 is also six. The baffles 116 are arranged eccentrically relative to the outer tube 11 so that the distance from each position of the baffle 116 to the center of the outer tube 11 is closest and largest along the extension direction of the plug-ins 13; and then adjacent baffles 116 are arranged at intervals to form an opening slot 114 for extending the plug-ins 13. The middle of the outer tube 11 is provided with guide slots 115 located on the inner side of the baffle 116 at both ends of the baffle 116, and the guide slots 115 are arranged concentrically with the outer tube 11. The plug-ins 13 are arc-shaped corresponding to the baffle 116, and the inner end of the plug-ins 13 is slidably matched with the guide slot 115 through the slide bar 131. When the plug plate 13 is in the retracted state, the outer end of the plug plate 13 is located in the opening groove 114 and close to the outer side of the baffle 116. When the plug plate 13 slides along the guide groove 115 through the inner end through the slide bar 131 under the rotation traction of the inner tube 12, the plug plate 13 rotates around the axis of the slide bar 131 by abutting against the baffle 116 to extend out of the opening groove 114 and insert into the soil.

[0054] It should be known that the longer the length of a single plug plate 13 is, the greater the support force it can provide to the protective tube 1. As for the circular structure of the protective tube 1, the maximum support force for the protective tube 1 is achieved by setting the plug plate 13 in an arc shape, and the arc-shaped plug plate 13 has the smallest installation requirement for the protective tube 1, and will not interfere with the inner tube 12 to affect the buried installation of the benchmark 3. At the same time, in order to ensure that the plug plate 13 can be stably extended to the outside of the outer tube 11, the opening size of the opening groove 114 is for the thickness of the plug plate 13. Then, after the plug plate 13 is extended to the outer tube 11, there is a gap between the plug plate 13 and the opening groove 114, which will cause moist soil and the like to enter the interior of the outer tube 11, making the internal environment of the outer tube 11 become humid and harsh, thereby accelerating oxidation; therefore, Figure 5 , Fig.11 and Fig.12 As shown, a mudguard 118 can be provided on the side of the opening slot 114, and the mudguard 118 is made of a flexible material, such as rubber. After the plug plate 13 extends out of the opening slot 114, one side of the plug plate 13 will be fitted and supported with one side of the opening slot 114 to achieve extension, and the other side of the plug plate 13 will be in contact with the mudguard 118, so that the opening slot 114 can be sealed to a certain extent after the plug plate 13 is extended, so as to reduce or prevent moisture, mud and sand from entering the interior of the outer tube 11.

[0055] For ease of understanding, the specific extension process of the plug board 13 will be described in detail below.

[0056] like Figure 5As shown, the front and rear ends of the baffle 116 can be defined along the extending direction of the plug plate 13; since the baffle 116 is eccentrically arranged, the front end of the baffle 116 is closer to or directly flush with the outer edge of the outer tube 11, and the rear end of the baffle 116 is away from the outer edge of the outer tube 11, that is, there is a certain spacing area between the rear part of the baffle 116 and the outer edge of the outer tube 11.

[0057] like Fig. 9 As shown, when the plug plate 13 is in a retracted state, most of the structure of the plug plate 13 will be located inside the outer tube 11 and close to or in contact with the corresponding baffle 116. At this time, the outer end of the plug plate 13 can be located in the interval area between the rear part of the previous baffle 116 and the outer edge of the outer tube 11, so that the previous baffle 116 can guide the extension of the subsequent plug plate 13.

[0058] like Fig.11 As shown, when the plug plate 13 needs to be extended, the inner tube 12 will rotate relative to the outer tube 11, so that the inner end of the plug plate 13 will slide along the guide groove 115 through the slide bar 131 under the drive of the inner tube 12. As the plug plate 13 slides, the plug plate 13 will be resisted by the rear end of the previous baffle 116, so that the plug plate 13 as a whole slides toward the previous baffle 116 through the slide bar 131; at the same time, the plug plate 13 resists the rear end of the previous baffle 116 and rotates around the axis of the slide bar 131 away from the previous baffle 116 until the plug plate 13 moves to the radial direction of the outer tube 11. The fully opened position of the plug plate 13 can be determined as the tangent of the plug plate 13 passes through the center position of the outer tube 11.

[0059] When the plug plate 13 needs to be retracted, the inner tube 12 only needs to be rotated in the opposite direction, so that the plug plate 13 is rotated around the axis of the slide rod 131 close to the previous baffle 116 by abutting against the front end of the corresponding baffle 116, until the plug plate 13 is reset to Fig. 9 The status shown is OK.

[0060] In this embodiment, Figure 8 and Fig.11 As shown, the outer end of the plug plate 13 is set at a sharp angle so that the plug plate 13 can be smoothly and easily inserted into the soil on the side of the marked hole. At least one side of the plug plate 13 is provided with a recessed cavity 130; the monitoring module includes a sensor installed in each recessed cavity 130 and a communication bus installed in the inner tube 12. The thickness of the sensor is less than the depth of the recessed cavity 130, and the adjacent protection tubes 1 are connected to the communication bus through the plugging of the inner tube 12, and then all the monitoring modules transmit signals through the communication bus.

[0061] It should be known that by setting the depth of the recessed cavity 130 to be greater than the thickness of the sensor, the extrusion force between the soil and the sensor can be reduced along the insertion direction of the plug board 13 during the insertion of the plug board 13 into the soil, thereby reducing or avoiding the extrusion damage of the soil to the sensor, so as to improve the service life of the sensor. In addition, for the stability of data transmission, a communication bus can be set in the inner tube 12, and the communication bus can be connected between adjacent protective tubes 1, so that the monitoring data of all sensors can be transmitted to the ground collection device in a wired manner. The recessed cavity 130 can be set on both sides of the plug board 13, or on one side of the plug board 13, and can be determined according to actual needs. In order to facilitate the description of the subsequent content, the subsequent content will be described by taking the setting of the sensor on one side of the plug board 13 as an example. The specific structure and working principle of the sensor for measuring parameters such as soil fluidity are well-known technologies for those skilled in the art, so they will not be elaborated in detail here.

[0062] It should also be known that there are many ways to connect the communication bus between adjacent protection tubes 1. A specific example is as follows: Figure 7 As shown in (1) and (2), the two ends of the inner tube 12 are respectively provided with a plug 1231 and a socket 1241 connected to the two ends of the corresponding communication bus. Therefore, when connecting adjacent inner tubes 12, one inner tube 12 can be plugged into the socket 1241 of another inner tube 12 through the plug 1231 to transfer data.

[0063] In this embodiment, Figure 7 As shown, there are multiple communication buses corresponding to a single monitoring module, and the multiple communication buses are electrically connected to all sensors at the same time; by setting up multiple communication buses, they can be used as backup communication buses, so that when one of the communication buses fails, the remaining communication buses can still transmit data. In two adjacent protection tubes, all the communication buses of one of the protection tubes are simultaneously connected to each of the communication buses of the other protection tube. When monitoring data is lost, the type of fault is determined and the specific fault location is located by analyzing the number of data transmissions of all monitoring modules, and then the protection tube 1 at the fault location is replaced; wherein, the types of faults include sensor damage and communication bus disconnection.

[0064] It should be noted that the specific number of communication buses can be determined according to actual needs, for example Figure 7 As shown in (1) and (2), the number of communication buses corresponding to each monitoring module is three. When adjacent protection tubes 1 are connected, data is transmitted from bottom to top. For a single protection tube 1, the lower end of each communication bus can simultaneously input three data signals, and the upper end can output one communication signal.

[0065] For ease of understanding, the following describes in detail the process of determining and locating the specific fault type of the monitoring module.

[0066] S1: Each section of the protection tube 1 can be marked from top to bottom as protection tube #1, protection tube #2, ..., protection tube #N; at the same time, the sensors set on different plug boards 13 on any k-th protection tube 1 can be marked as sensor #k_1, sensor #k_2, ..., sensor #k_n. The communication bus corresponding to any k-th protection tube 1 can be marked as communication bus #k_1, communication bus #k_2, ..., communication bus #k_x. The values ​​of N, n and x can be set according to actual needs, for example, N is 15, n is 6, and x is 3.

[0067] S2: When the data of sensor #k_i is lost, it means that sensor #k_i is faulty; at this time, the faulty protection tube 1 can be located as protection tube #k, and the specific position of protection tube 1 can be determined according to the value of k to facilitate subsequent replacement.

[0068] S3: When multiple copies of the data of sensor #k_1, sensor #k_2, ..., sensor #k_n corresponding to protection tube #k are all lost, it can be said that a communication bus in a certain protection tube 1 has failed; at this time, the specific position of the failed protection tube 1 can be located according to the number of lost data to facilitate subsequent replacement.

[0069] It should be known that the data of all sensors in protection tube #k can form multiple groups as the data is transmitted, that is, the number of data groups can be expanded during the bottom-up transmission of data. For a group of sensors in protection tube #k, the number of data groups when it is transmitted to the ground acquisition equipment is x(k-1); that is, each time the data passes through a protection tube 1, the group of data will be expanded by x copies, so that when it passes through k-1 protection tubes 1 and is transmitted to the ground acquisition equipment, the group of data will be expanded by x(k-1) copies. If the number of data lost by a group of sensors is y, the specific position of the faulty protection tube 1 can be located according to [x(k-1)-y] / x.

[0070] In this embodiment, Figure 4 , Figures 14 to 16As shown, the protection tube 1 further includes at least one group of positioning components 15; the positioning components 15 are slidably mounted with the inner tube 12 in the radial direction, and the multiple positioning components 15 of each group are equidistantly arranged along the circumferential direction of the inner tube 12. When the benchmark 3 is buried, the inner tube 12 is rotated to drive the positioning components 15 to cooperate with the outer tube 11, and then the multiple positioning components 15 of each group are approached along the radial direction of the inner tube 12 to form a positioning hole corresponding to the diameter of the benchmark 3; thereby, the benchmark 3 is improved in rigidity of the buried rod by cooperating with the positioning hole.

[0071] It should be known that the specific number of groups of positioning components 15 and the specific quantity of each group can be selected according to the actual needs of those skilled in the art. Figure 4 As shown, there are two groups of positioning components 15 , which are respectively arranged at the upper and lower parts of the inner tube 12 . There are three positioning components 15 in each group, and the three positioning components 15 are evenly spaced along the circumferential direction of the inner tube 12 .

[0072] It is understandable that when burying the benchmark 3, in order to ensure the accuracy of the subsequent monitoring of the benchmark 3, a gap needs to be maintained between the protective hole 120 of the protective tube 1 and the benchmark 3 to avoid interference between the benchmark 3 and the side wall of the protective hole 120. The burying of the benchmark 3 requires that the benchmark 3 be fully inserted into the marking hole first, and then the benchmark 3 is inserted into the soil at the bottom of the marking hole to a certain depth on the ground by hydraulic drive. However, the depth of the marking hole is generally 15m to 20m. If a gap is maintained between the benchmark 3 and the protective hole 120, when the benchmark 3 is pressed and buried, the benchmark 3 will be too long to cause insufficient rigidity and bend easily, which will inevitably cause interference between the benchmark 3 and the protective hole 120, and even for harder geology, the burying of the benchmark 3 may not be completed. Therefore, when burying the marker 3, the positioning assembly 15 is provided to position and support the marker 3, and at least one supporting point of the marker 3 is positioned through each section of the protective tube 1 to ensure that the marker 3 has sufficient rigidity to be inserted into the soil at the bottom of the marker hole.

[0073] It should be known that the embedding of the benchmark 3 is carried out after the installation of the protective tube 1 is completed, and the driving of the positioning component 15 and the plug-in plate 13 are both achieved by the rotation of the inner tube 12; therefore, in order to ensure that the positioning of the benchmark 3 by the positioning component 15 does not interfere with the plug-in of the plug-in plate 13, the driving structure of the inner tube 12 needs to be intermittently designed to meet the needs of both at the same time.

[0074] In this embodiment, there are multiple structures of the inner tube 12 that can simultaneously drive the positioning assembly 15 and the plug board 13. For ease of understanding, one of the structures will be described in detail below. Figure 6 , Figures 9 to 16As shown, a hinge groove 121 is provided in the middle of the inner tube 12, and the inner end of the plug plate 13 is hinged to the hinge groove 121 through the traction assembly 14, and the size of the hinge groove 121 is larger than the corresponding end size of the traction assembly 14. The upper and lower inner walls of the outer tube 11 are both provided with a plurality of pressing blocks 117 corresponding to the number of the positioning assemblies 15 along the circumferential direction, and the plurality of pressing blocks 117 can be driven and matched with the corresponding positioning assemblies 15.

[0075] When the plug plate 13 is in a retracted state, the positioning assembly 15 and the corresponding pressing block 117 are spaced apart in the circumferential direction. When the inner tube 12 is against the traction assembly 14 through the first side of the hinge groove 121 to drive the plug plate 13 to fully extend, the positioning assembly 15 is synchronously rotated forward with the inner tube 12 to pass over the corresponding pressing block 117. When the benchmark 3 is buried, the inner tube 12 is reversely rotated to the second side of the hinge groove 121 to abut against the traction assembly 14, so that the positioning assembly 15 is synchronously rotated with the inner tube 12 to face the pressing block 117, and then the positioning assembly 15 is squeezed by the pressing block 117 to move radially to form a positioning hole. After the burying of the benchmark 3 is completed, the inner tube 12 is rotated forward again to the first side of the hinge groove 121 to abut against the traction assembly 14.

[0076] It should be known that the pressing block 117 needs to facilitate the positioning assembly 15 to pass smoothly, so both sides of the pressing block 117 are arc surfaces or inclined surfaces. At the same time, in order to ensure that the pressing block 117 squeezes the positioning assembly 15 stably, a corresponding smooth section needs to be provided on the pressing block 117. The number of traction assemblies 14 corresponds to the number of plug boards 13.

[0077] Specifically, Figure 6 , Figures 14 to 16 As shown, the pressing block 117 includes a first pressing section 1171, a second pressing section 1172 and a third pressing section 1173 arranged in sequence along the circumferential direction. The first pressing section 1171 and the third pressing section 1173 are inclined surfaces or arc-shaped surfaces, and the second pressing section 1172 is an arc section in the same direction as the inner tube 12. For ease of understanding, the specific working process of the inner tube 12 will be described in detail below in conjunction with the accompanying drawings.

[0078] (1) When the protective tube 1 is in the set position, such as Fig. 9 and Fig.14 As shown, the insert plates 13 are now retracted inside the outer tube 11, and the positioning assembly 15 is spaced apart from the corresponding pressing block 117 in the circumferential direction, and a reference line a can be set. At this time, the first side of the hinge groove 121 on the inner tube 12 abuts against the traction assembly 14.

[0079] (2) If Fig.10 and Fig.11As shown, when the inner tube 12 rotates clockwise, the inner tube 12 can abut against the traction assembly 14 through the first side of the hinge slot 121 to drive the plug plate 13 to extend. When the plug plate 13 is in a fully extended state, the inner tube 12 rotates clockwise by an angle α to reach the position of the reference line b. At the same time, as shown in FIG. Fig.15 As shown, the rotation of the inner tube 12 will drive the positioning assembly 15 to rotate by an angle α, so that the positioning assembly 15 passes over the first pressing section 1171 and the second pressing section 1172 of the corresponding pressing block 117 to reach the position of the third pressing section 1173. At this time, the positioning assembly 15 is basically in a state away from the protective hole 120, so that the protective hole 120 has enough space for inserting the benchmark 3.

[0080] (3) After completing the insertion of the marker 3, Fig.10 and Fig.12 As shown, the inner tube 12 will rotate counterclockwise by an angle of β to reach the position of the reference line c; because the size of the hinge groove 121 is larger than the size of the traction assembly 14, there is an intermittent space in the process of the inner tube 12 rotating counterclockwise, that is, in the process of the inner tube 12 rotating counterclockwise to the reference line c, the hinge groove 121 just fits with the connecting end of the traction assembly 14 through the second side, so that the traction assembly 14 is basically inhibited during this process, and the plug board 13 can be kept in the maximum stable open state. At the same time, Fig.16 As shown, the positioning assembly 15 will rotate counterclockwise to the position of the reference line c synchronously with the inner tube 12. At this time, the positioning assembly 15 will be offset against the second pressing section 1172 of the pressing block 117, so that the positioning assembly 15 is in a state closest to the protective hole 120 to form a positioning hole corresponding to the size of the benchmark rod 3 to realize the positioning of the benchmark rod 3.

[0081] (4) After the burying of the pole 3 is completed, in order to ensure the accuracy of the pole 3 in the subsequent data monitoring process, the positioning assembly 15 needs to be reset to a state away from the protection hole 120 to avoid contact interference with the pole 3. That is, the inner tube 12 is rotated clockwise to the position of the reference line b again; during this process, the hinge groove 121 contacts the traction assembly 14 again through the first side to ensure that the traction assembly 14 remains basically stationary during this process.

[0082] In this embodiment, there are various specific structures of the traction assembly 14 that can achieve the above functions. One specific structure of the traction assembly 14 is as follows: Figures 9 to 12As shown, the traction assembly 14 includes a first traction plate 141 and a second traction plate 142 which are hinged to each other at their ends; the other end of the first traction plate 141 is hinged to the inner middle part of the plug plate 13, and the other end of the second traction plate 142 is hinged to the hinge groove 121 on the inner tube 12. Therefore, when the inner tube 12 performs the above steps (3) and (4), the relative position change between the first traction plate 141 and the second traction plate 142 can further compensate for the movement trend driven by the rotation of the inner tube 12, so as to further maintain the plugging stability of the plug plate 13 in the above process.

[0083] In this embodiment, there are various specific structures of the positioning component 15 that can realize the above functions. One specific structure of the positioning component 15 is as follows: Figures 14 to 16 As shown, the positioning assembly 15 includes a slide plate 151, a spring 152 and a roller 153. The slide plate 151 is slidably mounted on the slide groove 122 arranged radially on the inner tube 12 and is elastically slidably connected to the inner tube 12 in a radial direction through the spring 152. The end of the slide plate 151 away from the protective hole 120 is an arc head 1510, so that when the positioning assembly 15 rotates with the inner tube 12, the slide plate 151 will be squeezed and matched with the pressing block 117 through the arc head 1510 to reduce wear. The roller 153 is rotatably mounted on the end of the slide plate 151 close to the protective hole 120, so that each group of positioning assemblies 15 can form a positioning hole by fitting with the marker 3 through the roller 153. Therefore, when the marker 3 is buried, the relative rolling of the roller 153 along the marker 3 reduces the obstruction of the positioning assembly 15 to the marker 3 in the buried direction.

[0084] Those skilled in the art should know that, for soil monitoring, it is necessary to monitor the forces of the soil at the same depth in the horizontal and vertical directions. Figure 4 , Figure 8 and Fig.13 As shown, the sensors of the monitoring module include a first sensor 41 and a second sensor 42; the first sensor 41 is installed in the recessed cavity 130 of the plug plate 13 to monitor the force of the soil in the horizontal direction as the plug plate 13 is extended; the second sensor 42 is installed in the extension component 16, and the extension component 16 can be extended and retracted along the through hole 119 set on the side wall of the outer tube 11 under the drive of the inner tube 12, so as to drive the second sensor 42 to extend to the outside of the outer tube 11 to realize the monitoring of the force of the soil in the vertical direction.

[0085] It should be noted that the specific structure and working principle of the first sensor 41 and the second sensor 42 are well known to those skilled in the art, so they will not be elaborated in detail here; at the same time, a fender 118 can be provided on the side of the perforation 119 to reduce or prevent wet mud from entering the outer tube 11. There are many specific structures of the extension assembly 16 that can achieve the above functions. For the convenience of setting, a structure similar to the traction assembly 14 can be adopted; that is, Fig.13 As shown, the extension assembly 16 includes a third traction plate 161 and a fourth traction plate 162. The installation method of the third traction plate 161 is consistent with the installation method of the second traction plate 142. One end of the fourth traction plate 162 is hingedly installed on the outer end of the third traction plate 161 relative to the inner tube 12, and the other end of the fourth traction plate 162 faces the corresponding through hole 119; the second sensor 42 is installed on the upper surface of the fourth traction plate 162, so that the second sensor 42 monitors the force of the soil in the vertical direction after the fourth traction plate 162 is extended. In order to ensure the accuracy of the monitoring results, the number of second sensors 42 can also be set to multiple, and the multiple second sensors 42 are arranged along the circumferential direction of the outer tube 11, and each second sensor 42 is installed on the corresponding extension assembly 16.

[0086] In this embodiment, Figure 1 , Figure 2 , Figures 17 to 19 As shown, the driving mechanism 2 includes a base 21, a plurality of transmission components 22 and a driving member. The base 21 is fixedly arranged on the ground and its center is aligned with the mark hole; the transmission components 22 are installed on the base 21 at equal intervals along the circumferential direction, and the transmission components 22 can be meshed with the rack plate 111 arranged axially on the outer side of the protection tube 1 through the gear 226. The driving member can drive the transmission component 22 to drive the gear 226 to rotate, thereby driving the protection tube 1 to move down or up along the mark hole.

[0087] It should be known that the specific number of the transmission assembly 22 and the rack plate 111 can be selected according to the actual needs of those skilled in the art, for example Fig.17 and Fig.19 As shown, there are three corresponding transmission components 22 and rack plates 111. The rack plates 111 are axially equal in length and arranged outside the outer tube 11 of the protection tube 1. The three rack plates 111 are arranged at equal intervals along the circumferential direction of the outer tube 11, thereby ensuring the stability of the driving mechanism 2 in lifting and lowering the protection tube 1.

[0088] In this embodiment, there are many specific structures of the transmission assembly 22 that can achieve the above functions, one of which is as follows: Figures 17 to 19As shown. The driving member is a ring gear 23, and the transmission assembly 22 includes a housing 221, a worm 222, a worm wheel 225, and a gear 226. The worm wheel 225 and the gear 226 are coaxially rotatably mounted on the housing 221 through a rotating shaft 224, the worm 222 is rotatably mounted on the housing 221 and meshes with the worm wheel 225, and the ring gear 23 can pass through the avoidance groove 2210 provided on each housing 221 to mesh with the gear shaft section 223 provided on each worm 222, and then the worm 222 is driven by rotating the ring gear 23 to drive the worm wheel 225 and the gear 226 to rotate synchronously.

[0089] It should be known that the self-locking of the transmission assembly 22 is achieved by utilizing the cooperation of the worm wheel 225 and the worm 222, and the protection tube 1 can be suspended at any position to facilitate the docking or disassembly of two protection tubes 1. The ring gear 23 can be driven manually, such as by setting a plurality of handles 231 on the outer side of the ring gear 23 along the circumferential direction, and by rotating the handles 231, the ring gear 23 can be rotated in the positive and negative directions, thereby achieving the lifting and lowering of the protection tube 1. Of course, the ring gear 23 can also be driven to rotate around the center of the base 21 by electric or other non-manual methods.

[0090] It should also be known that the lifting and lowering drive of the protection tubes 1 of different sizes can be satisfied by simply adjusting the installation position of each transmission assembly 22 relative to the base 21. At the same time, the rotation of the inner tube 12 can be manual, such as using a special hexagonal wrench to drive the inner tube 12 to rotate, or it can be driven by electric or other non-manual methods. If the rotation of the inner tube 12 and the gear ring 23 is non-manual, since the two do not need to rotate at the same time and the rotation center of the two is the same, the two can be driven separately by the same driving device.

[0091] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application. The present application may have various changes and improvements without departing from the spirit and scope of the present application, and these changes and improvements fall within the scope of the present application for which protection is sought. The scope of protection claimed by the present application is defined by the attached claims and their equivalents.
