Detailed implementation manners

[0041] Next, in combination with the detailed implementation manners, the present application will be further described. It should be noted that, on the premise of no conflict, any combination can be formed among the following-described embodiments or technical features to form a new embodiment.

[0042] In the description of the present application, it should be noted that for the orientation terms, such as the terms "center", "transverse", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., the orientation and position relationships indicated are based on the orientation or position relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific protection scope of the present application.

[0043] 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 do not necessarily describe a specific order or sequence.

[0044] The terms "including" and "having" and any variations thereof in the description and claims of the present application are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units does not necessarily have to be limited to those clearly listed steps or units, but may include other steps or units that are not clearly listed or are inherent to these processes, methods, products or devices.

[0045] One preferred embodiment of the present application is as follows Figure 1 As shown, a micro-perturbation in-situ geological multi-parameter intelligent monitoring device includes a driving mechanism 2, multi-section modular protection pipes 1, a reference rod 3, and multiple monitoring modules. Any two protection pipes 1 can be detachably and fixedly connected. Thus, when installing the monitoring device of the present application, the number of protection pipes 1 required can be selected according to the depth of the marked hole reserved on the ground; then, under the drive of the driving mechanism 2 installed on the ground, the corresponding number of protection pipes 1 are inserted into the marked hole; and during the insertion process, when each protection pipe 1 is inserted, another protection pipe 1 can be detachably and fixedly connected to the inserted protection pipe 1. Through the sequential connection and insertion of the protection pipes 1, until all the protection pipes 1 are inserted into the marked hole and connected to form a whole, so that the protection holes 120 in the centers of all the protection pipes 1 can be interconnected and aligned. Thus, when installing the reference rod 3, it can be inserted along the protection hole 120 to the bottom of the marked hole for geological settlement monitoring. The multiple monitoring modules are correspondingly installed on each protection pipe 1 and can be opened when each protection pipe 1 is inserted into the set installation position, so as to ensure the stable protection of the reference rod 3 and ensure the accuracy of the monitoring data of the reference rod 3. At the same time, during the opening process of the protection pipe 1, the correspondingly installed monitoring module can be inserted into the soil on the side of the marked hole as the protection pipe 1 opens, so as to realize the monitoring of the fluidity of the soil; and the multiple monitoring modules can monitor the soil at different depths of the marked hole to ensure the monitoring accuracy and monitoring range of the data.

[0046] It should be known that when conducting geological settlement monitoring of the soil, it is necessary to first drill a marked hole with a corresponding depth on the ground. The specific depth of the marked hole can be selected according to the specific geological conditions, generally between 15m and 20m. After the drilling of the marked hole is completed, it is necessary to set up a protection structure to protect the soil on the side of the marked hole to avoid the interference of soil flow during continuous monitoring on the reference rod 3, resulting in inaccurate data for geological settlement monitoring. The traditional protection structure for geological settlement monitoring is generally set up using an expanding structure, that is, after the protection structure is installed at the set position, the expanding structure is opened through the corresponding pull rope on the ground, so that the expanding structure expands to abut against the side of the marked hole. However, the marked hole may not necessarily present a regular circular structure after drilling, which will cause a certain degree of inclination of the protection structure during the expansion process of the expanding structure; and for softer soil areas, the abutment of the expanding structure against the soil on the side of the marked hole may not provide sufficient supporting force to meet the stable support of the protection structure.

[0047] In this embodiment, after the protection pipe 1 is installed at a 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 pipe 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 pipe 1, and further, it can effectively avoid the interference between the protection hole 120 at the center of the protection pipe 1 and the benchmark 3 to ensure the accuracy of the monitoring data of the geological settlement by the benchmark 3.

[0048] Since the protection of the standard hole by the protection pipe 1 requires the support structure to be inserted into the soil, the corresponding monitoring module can be installed on the support structure of the protection pipe 1, so that when the support structure is inserted into the soil, the monitoring module can be carried along and inserted. In this way, while the protection pipe 1 realizes stable protection of the standard hole, it can also monitor the fluidity of the soil on the side of the standard hole through the monitoring module. And because the protection pipe 1 has multiple sections, monitoring modules can be installed on each section of the protection pipe 1. Furthermore, through multiple monitoring modules, the soil at different depths of the standard hole can be monitored. The number of a group of monitoring modules corresponding to each section of the protection pipe 1 is multiple, so as to ensure the accuracy of monitoring through data monitoring in different directions by multiple monitoring modules at the same depth position. Of course, the monitoring module can also detect other parameters of the soil.

[0049] When monitoring the soil data through the monitoring module, since the environment in the standard hole is a humid environment, long-term data monitoring may cause damage to the monitoring module or other related structures. If the protection pipe 1 adopts an integral structure, it is necessary to pull out all the protection pipes 1 from the standard hole and perform all disassembly to complete the repair of the fault. In this embodiment, only the specific fault location needs to be located according to the abnormal data condition of the monitoring module, and then the protection pipe 1 is pulled out of the standard hole by the driving mechanism 2 until the protection pipe 1 corresponding to the fault location is exposed on the ground. At this time, only the protection pipe 1 at the fault location needs to be replaced with a new one, and then the disassembled protection pipes 1 without faults are re-inserted into the standard hole under the drive of the driving mechanism 2. Compared with the integral structure, the multi-section modular protection pipe 1 in this embodiment can effectively reduce the maintenance difficulty of the fault and improve the efficiency of fault maintenance. Specifically, it can be assumed that the protection pipe 1 has fifteen sections, and the fault location is the fifth section from top to bottom. Then the driving mechanism 2 only needs to lift the protection pipe 1 by the height of five sections to disassemble and replace the faulty protection pipe 1.

[0050] It should also be known that the specific length of each section of the protection pipe 1 can be selected by those skilled in the art according to actual needs; the lengths of the protection pipes 1 can be unified, or the lengths of the protection pipes 1 can be non-uniform to facilitate fine-tuning the installation of the protection pipe 1 according to the depth of the standard hole. Generally speaking, the specific length of the protection pipe 1 is between 50 cm and 150 cm.

[0051] In this embodiment, there are various specific structures of the protection tube 1. For the convenience of understanding, one of the specific structures will be described in detail below. As Figures 2 to 4 , Figure 9 and Figure 11 shown, the protection tube 1 includes an outer tube 11, an inner tube 12, and at least one set of insertion plates 13. Adjacent protection tubes 1 can be detachably fixedly connected through the outer tube 11, and when the connection of adjacent protection tubes 1 is completed, the inner tubes 12 between adjacent protection tubes 1 can be inserted in a manner that allows synchronous rotation. The inner tube 12 is rotatably installed inside the outer tube 11, and a protection hole 120 is provided at the center of the inner tube 12. Multiple sets of insertion plates 13 can be arranged at intervals along the axial direction of the outer tube 11, and multiple insertion plates 13 in each set can be arranged in the circumferential direction of the outer tube 11 in the area between the outer tube 11 and the inner tube 12. The insertion plates 13 can be in guiding cooperation with the outer tube 11, and at the same time, the insertion plates 13 can be in traction cooperation with the inner tube 12, and the monitoring module is installed on the insertion plates 13. Thus, when all the protection tubes 1 are inserted into the set positions of the standard holes, the inner tube 12 of the uppermost protection tube 1 can be rotated on the ground to drive all the inner tubes 12 to rotate relative to the outer tube 11, and further, all the insertion plates 13 of each section of the protection tube 1 can be driven to carry the monitoring module to extend out of the corresponding outer tube 11 and insert into the soil at different depths of the standard holes.

[0052] It should be known that the number of sets of insertion plates 13 corresponding to each section of the protection tube 1 and the specific number of insertion plates 13 in each set can be set according to the actual needs of those skilled in the art; for example Figure 4 shown, the number of sets of insertion plates 13 corresponding to each section of the protection tube 1 is one set, and the number of insertion plates 13 in one set is six; this set of insertion plates 13 can be arranged in the middle area of the protection tube 1.

[0053] It can be understood that there are various specific ways for adjacent protection tubes 1 to be detachably connected through the outer tube 11; one specific example is as Figure 2 and Figure 3As shown, a connection block 112 and a connection groove 113 are respectively provided at the upper end and the lower end of the single outer tube 11. The sizes and positions of the connection block 112 and the connection groove 113 correspond to each other, and the numbers of the connection block 112 and the connection groove 113 are both set to be multiple, such as three or four, etc.; the multiple connection blocks 112 and connection grooves 113 can be arranged at equal intervals along the circumferential direction of the outer tube 11. Thus, when connecting adjacent protection tubes 1, the connection block 112 at the upper end of the lower protection tube 1 can be correspondingly inserted into the connection groove 113 at the lower end of the upper protection tube 1, and then a pin shaft penetrates through the inserted connection block 112 and connection groove 113 along the radial direction of the outer tube 11 at the same time, so as to form a detachable fixed connection between two adjacent protection tubes 1. When disassembly is required, only the pin shaft needs to be pulled out; of course, for stable connection, the detachable connection of the two protection tubes 1 can also be realized by screwing a screw into the screw holes penetrating the connection block 112 and the connection groove 113.

[0054] It can also be understood that there are also various ways of rotatable insertion between adjacent inner tubes 12. One specific example is as Figure 4 and Figure 7 shown. The upper end of the inner tube 12 is an insertion joint 123 with a non-circular cross-section, and the lower end of the inner tube 12 is a socket 124 with a non-circular cross-section and adapted to the insertion joint 123. There are various specific shapes of common non-circular cross-sections, such as ellipse and polygon, etc. In this embodiment, the insertion joint 123 and the socket 124 with a regular hexagon cross-section are preferably adopted. Thus, when connecting two adjacent protection tubes 1, the corresponding inner tubes 12 of the two adjacent protection tubes 1 will be respectively inserted through the insertion joint 123 of one inner tube 12 and the socket 124 of the other inner tube 12; furthermore, when the inner tube 12 at the uppermost position on the ground rotates, through the insertion of the insertion joint 123 and the socket 124, all the inner tubes 12 can be driven to rotate relative to the outer tube 11. During the rotation of the inner tube 12 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 at the uppermost position on the ground can be restricted to be stationary in other ways.

[0055] In this embodiment, as Figure 5 、 Figure 8 、 Figure 9 and Figure 11As shown in the figure, a plurality of arc-shaped baffles 116 are equidistantly arranged along the circumferential direction in the middle of the outer tube 11. The specific number of the baffles 116 corresponds to the number of the insertion plates 13 in each group. For example, if the number of the insertion plates 13 is six, the number of the baffles 116 is also six. The baffles 116 are eccentrically arranged relative to the outer tube 11, so that along the extending direction of the insertion plates 13, the distance from each position of the baffles 116 to the center of the outer tube 11 increases at the nearest; and then the adjacent baffles 116 are spaced apart to form an opening groove 114 for the insertion plates 13 to extend out. At both ends of the baffles 116 in the middle of the outer tube 11, guide grooves 115 located inside the baffles 116 are provided. The guide grooves 115 are concentric with the outer tube 11. The insertion plates 13 are in an arc shape corresponding to the baffles 116. The inner ends of the insertion plates 13 are slidably matched with the guide grooves 115 through sliding rods 131. When the insertion plates 13 are in a contracted state, the outer ends of the insertion plates 13 are located in the opening groove 114 and close to the outside of the baffles 116. When the insertion plates 13 slide along the guide grooves 115 through the sliding rods 131 under the rotational traction of the inner tube 12 at the inner ends, the insertion plates 13 rotate around the axis of the sliding rods 131 by abutting against the baffles 116 to extend out of the opening groove 114 and insert into the soil.

[0056] It should be known that the longer the length of a single insertion plate 13 is, the greater the supporting force that can be provided for the protection tube 1. For the circular-structured protection tube 1, by arranging the insertion plates 13 in an arc shape, the maximum supporting force for the protection tube 1 can be achieved, and the installation requirement of the arc-shaped insertion plates 13 for the protection tube 1 is the smallest, and there will be no interference with the inner tube 12 to affect the pole embedding installation of the benchmark 3. At the same time, in order to ensure that the insertion plates 13 can stably extend to the outside of the outer tube 11, the opening size of the opening groove 114 is for the thickness of the insertion plates 13. Then, after the insertion plates 13 extend to the outside of the outer tube 11, there is a gap between the insertion plates 13 and the opening groove 114, which will cause wet soil and the like to enter the inside of the outer tube 11, making the internal environment of the outer tube 11 become wet and harsh and accelerating oxidation; therefore, as Figure 5 、 Figure 11 and Figure 12 shown, a mud guard 118 can be provided on the side of the opening groove 114. The mud guard 118 is made of a flexible material, such as rubber, etc.; after the insertion plates 13 extend out of the opening groove 114, one side of the insertion plates 13 will be in contact and supported with one side of the opening groove 114 to achieve extension, and the other side of the insertion plates 13 will contact the mud guard 118, so that a certain degree of sealing can be ensured for the opening groove 114 after the insertion plates 13 extend out, so as to reduce or avoid wet mud and sand and the like from entering the inside of the outer tube 11.

[0057] For the convenience of understanding, the specific extending process of the insertion plates 13 will be described in detail below.

[0058] As Figure 5As shown, the front and rear ends of the baffle 116 can be defined along the extending direction of the insertion 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 interval area between the rear part of the baffle 116 and the outer edge of the outer tube 11.

[0059] As Figure 9 shown, when the insertion plate 13 is in the retracted state, most of the structure of the insertion 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 insertion 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 subsequent extension of the insertion plate 13.

[0060] As Figure 11 shown, when the insertion plate 13 needs to extend, the inner tube 12 will rotate relative to the outer tube 11, so that the inner end of the insertion plate 13 will slide along the guide groove 115 through the slide bar 131 under the drive of the inner tube 12. As the insertion plate 13 slides, the insertion plate 13 will be resisted by the rear end of the previous baffle 116, so that the whole insertion plate 13 slides towards the direction close to the previous baffle 116 through the slide bar 131; at the same time, the insertion plate 13 rotates away from the previous baffle 116 around the axis of the slide bar 131 by resisting against the rear end of the previous baffle 116 until the insertion plate 13 moves to tend to the radial direction of the outer tube 11. For the fully open position of the insertion plate 13, it can be determined that the tangent line of the insertion plate 13 passes through the central position of the outer tube 11.

[0061] When the insertion plate 13 needs to be retracted again, just rotate the inner tube 12 in the reverse direction, so that the insertion plate 13 rotates around the axis of the slide bar 131 towards the previous baffle 116 by resisting against the front end of the corresponding baffle 116 until the insertion plate 13 is reset to Figure 9 the state shown.

[0062] In this embodiment, as Figure 8 and Figure 11 shown, the outer end of the insertion plate 13 is provided with a sharp angle so that the insertion plate 13 can be smoothly and easily inserted into the soil on the side of the marking hole. At least one side of the insertion plate 13 is provided with a recessed cavity 130; the monitoring module includes sensors 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. Adjacent protection tubes 1 are connected by inserting the inner tube 12 to connect the communication bus, and then all the monitoring modules transmit signals through the communication bus.

[0063] It should be known that by setting the depth of the concave cavity 130 to be greater than the thickness of the sensor, during the process of inserting the insertion plate 13 into the soil, along the insertion direction of the insertion plate 13, the extrusion force between the soil and the sensor can be reduced, thereby reducing or avoiding the extrusion damage of the soil to the sensor and improving the service life of the sensor. And for the stability of data transmission, a communication bus can be arranged in the inner tube 12, and the communication buses can be connected between adjacent protection tubes 1, so as to transmit the monitoring data of all sensors to the ground acquisition device in a wired manner. The concave cavity 130 can be arranged on both sides of the insertion plate 13 or on one side of the insertion plate 13, and can be specifically determined according to actual needs. For the convenience of subsequent description, the subsequent content will take the example of arranging the sensor on one side of the insertion plate 13. The specific structure and working principle of the sensor for measuring parameters such as soil fluidity are well-known technologies to those skilled in the art, so they will not be elaborated in detail here.

[0064] It should also be known that there are various connection methods for the communication buses between adjacent protection tubes 1. One specific example is as Figure 7 shown in (1) and (2) in the figure. Plugs 1231 and sockets 1241 connected to both ends of the corresponding communication bus are respectively arranged at both ends of the inner tube 12. Thus, 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 for data transition transmission.

[0065] In this embodiment, as Figure 7 shown in the figure, 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 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. Among two adjacent protection tubes, all the communication buses of one of the protection tubes are connected to each communication bus of the other protection tube at the same time. When monitoring data is lost, by analyzing the data transmission quantity of all monitoring modules, the type of the fault is determined and the specific fault location is located, and then the protection tube 1 at the fault location is replaced; among them, the types of faults include sensor damage and communication bus open circuit.

[0066] It should be known that the specific number of communication buses can be determined according to actual needs. For example, Figure 7 shown in (1) and (2) in the figure, the number of communication buses corresponding to each monitoring module is three. When connecting adjacent protection tubes 1, data is transmitted from bottom to top. For a single protection tube 1, three data signals can be input simultaneously at the lower end of each of its communication buses, and one communication signal can be output at the upper end.

[0067] For the convenience of understanding, the judgment and positioning processes of the specific fault types of the monitoring module will be described in detail below.

[0068] S1: Each protection tube 1 can be marked as protection tube #1, protection tube #2, …, protection tube #N from top to bottom; at the same time, the sensors arranged 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 taken as 15, n is taken as 6, and x is taken as 3.

[0069] S2: When the data of sensor #k_i is lost, it can be indicated that sensor #k_i has a fault; 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.

[0070] S3: When the data of all sensors #k_1, sensor #k_2, …, sensor #k_n corresponding to protection tube #k is lost in multiple copies, it can be indicated that there is a fault in the communication bus in a certain protection tube 1; at this time, the specific position of the faulty protection tube 1 can be located according to the number of lost data copies to facilitate subsequent replacement.

[0071] It should be known that for the data of all sensors in protection tube #k, multiple groups can be formed during data transmission, that is, during the bottom-up data transmission process, the number of data groups can spread. For a group of sensors in protection tube #k, the number of data groups when it is transmitted to the ground acquisition device is x(k - 1); that is, every time the data passes through a protection tube 1, this group of data will be expanded by x copies. Thus, when it is transmitted to the ground acquisition device after passing through k - 1 protection tubes 1, this group of data will be expanded by x(k - 1) copies. If the number of lost copies of a certain group of sensor data is y, the specific position of the faulty protection tube 1 can be located according to [(x(k - 1) - y) / x].

[0072] In this embodiment, such as Figure 4 、 Figures 14 to 16As shown, the protection tube 1 further includes at least one set of positioning components 15; the positioning components 15 are slidably installed along the radial direction with the inner tube 12, and multiple positioning components 15 in each group are equidistantly arranged along the circumferential direction of the inner tube 12. When burying the benchmark 3, by rotating the inner tube 12 to drive the positioning components 15 to cooperate with the outer tube 11, and then multiple positioning components 15 in each group approach along the radial direction of the inner tube 12 to form positioning holes corresponding to the diameter of the benchmark 3; thus, the benchmark 3 is matched with the positioning holes to improve the stiffness of the buried pole.

[0073] It should be known that the specific number of groups of the positioning components 15 and the specific quantity in each group can be selected according to the actual needs of those skilled in the art. For example Figure 4 As shown, the number of groups of the positioning components 15 is two, and they are respectively arranged at the upper and lower parts of the inner tube 12. The number of positioning components 15 in each group is three, and the three positioning components 15 are equidistantly arranged along the circumferential direction of the inner tube 12.

[0074] It can be understood that when burying the benchmark 3, in order to ensure the accuracy of subsequent monitoring of the benchmark 3, a gap needs to be maintained between the protection hole 120 of the protection tube 1 and the benchmark 3 to avoid interference between the benchmark 3 and the side wall of the protection hole 120. When burying the benchmark 3, the benchmark 3 needs to 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 by hydraulic drive on the ground. However, the depth of the marking hole is generally between 15m and 20m. If a gap is maintained between the benchmark 3 and the protection hole 120, when pressing and burying the benchmark 3, the benchmark 3 will have insufficient stiffness due to its excessive length and is prone to bending, which will inevitably cause interference between the benchmark 3 and the protection hole 120, and even the benchmark 3 may not be buried in relatively hard geology. Therefore, in this embodiment, when burying the benchmark 3, the positioning components 15 are set to position and support the benchmark 3, and each section of the protection tube 1 positions the benchmark 3 at at least one support point to ensure that the benchmark 3 has sufficient stiffness to be inserted into the soil at the bottom of the marking hole.

[0075] It should be known that the burying of the benchmark 3 is carried out after the installation of the protection tube 1 is completed, and the driving of both the positioning components 15 and the plug board 13 relies on the rotation of the inner tube 12; therefore, in order to ensure that the positioning of the benchmark 3 by the positioning components 15 does not interfere with the insertion of the plug board 13, the driving structure of the inner tube 12 needs to be designed intermittently to meet the requirements of both.

[0076] In this embodiment, there are various structures of the inner tube 12 that can simultaneously drive the positioning components 15 and the plug board 13. For the convenience of understanding, one of the structures will be described in detail below. As Figure 6 、 Figures 9 to 16As shown in the figure, a hinge groove 121 is provided in the middle of the inner tube 12. The inner end of the insertion plate 13 is hinged to the hinge groove 121 through a traction assembly 14, and the size of the hinge groove 121 is larger than the corresponding end size of the traction assembly 14. On the inner walls of the upper and lower parts of the outer tube 11, a plurality of pressing blocks 117 corresponding to the number of the positioning assemblies 15 are arranged along the circumferential direction, and the plurality of pressing blocks 117 can be in driving cooperation with the corresponding positioning assemblies 15.

[0077] When the insertion plate 13 is in a contracted state, the positioning assembly 15 and the corresponding pressing block 117 are arranged at intervals in the circumferential direction. When the inner tube 12 abuts against the traction assembly 14 through the first side of the hinge groove 121 to drive the insertion plate 13 to fully extend, the positioning assembly 15 rotates forward synchronously with the inner tube 12 until it passes over the corresponding pressing block 117. When burying the benchmark 3, the inner tube 12 is rotated reversely until the second side of the hinge groove 121 abuts against the traction assembly 14, so that the positioning assembly 15 rotates synchronously with the inner tube 12 until it faces the pressing block 117, and then the positioning assembly 15 moves radially under the extrusion of the pressing block 117 to form a positioning hole. After the benchmark 3 is buried, the inner tube 12 is rotated forward again until the first side of the hinge groove 121 abuts against the traction assembly 14.

[0078] It should be noted that the pressing block 117 needs to be able to facilitate the positioning assembly 15 to pass smoothly. Therefore, both sides of the pressing block 117 are arc surfaces or inclined surfaces. At the same time, in order to ensure the stable extrusion of the pressing block 117 on the positioning assembly 15, a corresponding smooth section needs to be provided on the pressing block 117. The number of the traction assemblies 14 corresponds to the number of the insertion plates 13.

[0079] Specifically, as Figure 6 、 Figures 14 to 16 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. Among them, the first pressing section 1171 and the third pressing section 1173 are inclined surfaces or arc surfaces, and the second pressing section 1172 is an arc section in the same direction as the inner tube 12. For the convenience of understanding, the specific working process of the inner tube 12 will be described in detail below with reference to the accompanying drawings.

[0080] (1) When the protection tube 1 is in the set position, as Figure 9 and Figure 14 shown, at this time, the insertion plates 13 are all contracted inside the outer tube 11, and at the same time, the positioning assemblies 15 are arranged at intervals in the circumferential direction with the corresponding pressing blocks 117. At this time, 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.

[0081] (2) As Figure 10 and Figure 11As shown, when the inner tube 12 rotates clockwise, at this time, the inner tube 12 can push against the traction assembly 14 through the first side of the hinge slot 121 to drive the plug board 13 to extend. When the plug board 13 is in the 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 Figure 15 shown, the rotation of the inner tube 12 will drive the positioning assembly 15 to also rotate by an angle α, so that the positioning assembly 15 crosses 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 protection hole 120, so that there is enough space in the protection hole 120 for the insertion of the benchmark 3.

[0082] After the insertion of the benchmark 3 is completed, as Figure 10 and Figure 12 shown, the inner tube 12 will rotate counterclockwise by an angle β to reach the position of the reference line c; since the size of the hinge slot 121 is larger than the size of the traction assembly 14, there is an intermittent space during the counterclockwise rotation of the inner tube 12, that is, during the counterclockwise rotation of the inner tube 12 to the reference line c, the hinge slot 121 just fits the connection end of the traction assembly 14 through the second side, so that the traction assembly 14 remains basically stationary during this process, and thus the plug board 13 can remain in the maximum stable open state. At the same time, as Figure 16 shown, the positioning assembly 15 will rotate counterclockwise synchronously with the inner tube 12 to the position of the reference line c. At this time, the positioning assembly 15 abuts against the second pressing section 1172 of the pressing block 117, so that the positioning assembly 15 is in the state closest to the protection hole 120 to form a positioning hole corresponding to the size of the benchmark 3 to realize the positioning of the benchmark 3.

[0083] After the benchmark 3 is buried, in order to ensure the accuracy of the benchmark 3 during subsequent data monitoring, the positioning assembly 15 needs to be reset to a state away from the protection hole 120 to avoid contact interference with the benchmark 3. That is, just rotate the inner tube 12 clockwise again to the position of the reference line b; during this process, the hinge slot 121 contacts the traction assembly 14 through the first side again to ensure that the traction assembly 14 remains basically stationary during this process.

[0084] In this embodiment, there are various specific structures of the traction assembly 14 that can achieve the above functions. One of the specific structures of the traction assembly 14 is as Figures 9 to 12As shown in the figure, 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 middle part of the inner side of the plug board 13, and the other end of the second traction plate 142 is hinged to the hinge groove 121 on the inner tube 12. Thus, 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 stable insertion of the plug board 13 during the above process.

[0085] In this embodiment, there are various specific structures of the positioning assembly 15 that can achieve the above functions. One of the specific structures of the positioning assembly 15 is as Figures 14 to 16 shown. The positioning assembly 15 includes a sliding plate 151, a spring 152 and a roller 153. The sliding plate 151 is slidably installed in the chute 122 radially arranged on the inner tube 12 and is elastically slidably connected to the inner tube 12 through the spring 152. One end of the sliding plate 151 away from the protection hole 120 is an arc head 1510. Thus, during the rotation of the positioning assembly 15 with the inner tube 12, the sliding plate 151 will be in extrusion fit with the pressing block 117 through the arc head 1510 to reduce wear. The roller 153 is rotatably installed at one end of the sliding plate 151 close to the protection hole 120, so that each group of positioning assemblies 15 forms a positioning hole by the fitting of the roller 153 with the benchmark 3. Thus, during the process of burying the benchmark 3, the relative rolling of the roller 153 along the benchmark 3 reduces the obstruction of the positioning assembly 15 to the benchmark 3 in the burying direction.

[0086] Those skilled in the art should know that for the monitoring of soil, it is necessary to monitor the forces of the soil at the same depth in the horizontal and vertical directions. Therefore, in this embodiment, as Figure 4 、 Figure 8 and Figure 13 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 concave cavity 130 of the plug board 13 to monitor the force of the soil in the horizontal direction as the plug board 13 extends; the second sensor 42 is installed on the extending assembly 16, and the extending assembly 16 can extend and retract along the through hole 119 provided 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.

[0087] It should be noted that the specific structures and working principles of the first sensor 41 and the second sensor 42 are well-known technologies to those skilled in the art, so they will not be elaborated in detail here; at the same time, a mudguard 118 can also be provided on the side of the perforation 119 to reduce or avoid the entry of wet soil into the outer pipe 11. There are various 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, as Figure 13 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 the same as that of the second traction plate 142. One end of the fourth traction plate 162 is hingedly installed at the outer end of the third traction plate 161 relative to the inner pipe 12, and the other end of the fourth traction plate 162 faces the corresponding perforation 119; the second sensor 42 is installed on the upper surface of the fourth traction plate 162 so that the second sensor 42 can monitor the force of the soil in the vertical direction after extending with the fourth traction plate 162. To ensure the accuracy of the monitoring results, multiple second sensors 42 can also be provided, and the multiple second sensors 42 are arranged along the circumferential direction of the outer pipe 11, and each second sensor 42 is installed on the corresponding extension assembly 16.

[0088] In this embodiment, as Figure 1 , Figure 2 , Figures 17 to 19 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 standard 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 engaged with a rack plate 111 axially arranged on the outside of the protection pipe 1 through a gear 226. The driving member can drive the transmission components 22 to drive the gear 226 to rotate, thereby driving the protection pipe 1 to move down or up along the standard hole.

[0089] It should be noted that the specific numbers of the transmission components 22 and the rack plate 111 can be selected according to the actual needs of those skilled in the art. For example, as Figure 17 and Figure 19 shown, the numbers of the transmission components 22 and the rack plate 111 are three corresponding ones. The rack plate 111 is axially equally long and arranged on the outside of the outer pipe 11 of the protection pipe 1, and the three rack plates 111 are arranged at equal intervals along the circumferential direction of the outer pipe 11, so as to ensure the lifting stability of the driving mechanism 2 for the protection pipe 1.

[0090] In this embodiment, there are various specific structures of the transmission components 22 that can achieve the above functions. One of the structures is as Figures 17 to 19As shown. The driving member is a gear ring 23, and the transmission assembly 22 includes a housing 221, a worm 222, a worm gear 225, and a gear 226. The worm gear 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 gear 225. The gear ring 23 can pass through the avoidance grooves 2210 provided on each housing 221 and mesh with the tooth shaft sections 223 provided on each worm 222. Thus, by rotating the gear ring 23, the worm 222 is driven to drive the worm gear 225 and the gear 226 to rotate synchronously.

[0091] It should be known that the self-locking of the transmission assembly 22 is achieved by utilizing the cooperation of the worm gear 225 and the worm 222. Thus, the protection tube 1 can be hovered at any position, facilitating the docking or disassembly of the two protection tubes 1. For the driving of the gear ring 23, a manual method can be adopted. For example, a plurality of handles 231 can be arranged on the outer side of the gear ring 23 along the circumferential direction. By rotating the handles 231, the forward and reverse rotation of the gear ring 23 can be achieved, thereby realizing the lifting of the protection tube 1. Of course, the gear ring 23 can also be driven to rotate around the center of the base 21 by an electric or other non-manual method.

[0092] It should also be known that by simply adjusting the installation positions of the transmission assemblies 22 relative to the base 21, the lifting drive of the protection tubes 1 with different sizes can be satisfied. At the same time, the rotation of the inner tube 12 can be manual. For example, a special hexagon wrench can be used to drive the inner tube 12 to rotate, or it can also be driven by an electric or other non-manual method. If the rotation of both the inner tube 12 and the gear ring 23 adopts a non-manual method, since they do not need to rotate simultaneously and their rotation centers are the same, the same driving device can be used to achieve separate driving for the two.

[0093] The basic principle, main features, and advantages of the present application have been described above. Those skilled in the art should understand that the present application is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present application. Without departing from the spirit and scope of the present application, various changes and improvements will occur to the present application, and these changes and improvements all fall within the scope of the present application claimed.
