Description

Technical Field

[0001] This invention relates to the field of monitoring equipment, and more specifically to GNSS-based slope deformation monitoring equipment and its usage method. Background Technology

[0002] Slope stability monitoring is a core safety assurance link during the construction and operation of projects such as highways, railways, mining, water conservancy projects, and building foundation pits. As engineering construction extends to complex geological environments, the requirements for the accuracy, real-time performance, and equipment reliability of slope displacement monitoring are increasing. With its all-weather, high-precision, and long-distance transmission advantages, GNSS has gradually replaced traditional monitoring methods such as manual measurement and inclinometers, becoming the mainstream technical solution for dynamic slope displacement monitoring. Correspondingly, GNSS slope monitoring equipment is also widely used in various engineering scenarios. Its installation stability and sensitivity to soil deformation directly determine the timeliness and effectiveness of slope instability early warning.

[0003] Currently, mainstream GNSS slope monitoring equipment on the market typically uses concrete platforms for anchoring during the on-site deployment phase to ensure the stability of the equipment in complex outdoor environments. This method often takes 10-20 days to install, significantly increasing labor and equipment costs. It may also cause delays in construction, missing critical monitoring windows for slope deformation. During the excavation of the foundation pit, the original structure of the soil at and around the monitoring point is directly damaged, altering the stress distribution within the soil and potentially inducing additional unnatural deformation. Therefore, a GNSS-based slope deformation monitoring device and its usage method are proposed. Summary of the Invention

[0004] To address the technical problems existing in the prior art, the present invention provides a GNSS-based slope deformation monitoring device and its usage method.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a GNSS-based slope deformation monitoring device, comprising a main pole, a bracket set on the top of the main pole, a solar panel and a system box respectively fixed to both sides of the bracket by bolts, a GNSS device set at the top of the main pole, the GNSS device being electrically connected to the bracket, the solar panel being electrically connected to the system box, a buried fixing rod assembly installed at the bottom of the main pole, an auxiliary fixing component installed inside the buried fixing rod assembly, and a buried auxiliary sleeve rod assembly for assisting in fixing the buried fixing rod assembly on the outside of the buried fixing rod assembly.

[0006] Preferably, the buried fixing rod assembly includes a buried fixing rod body and a connecting threaded sleeve. The buried fixing rod body is buried in the soil layer, and the connecting threaded sleeve is welded to the top of the buried fixing rod body. The connecting threaded sleeve is used for threaded connection with the bottom of the main rod.

[0007] Preferably, the auxiliary fixing assembly includes a support plate, a rotating seat, a screw, a threaded sleeve, an insert rod assembly, and a guide hole group. The support plate is welded to the middle position inside the main body of the lower embedded fixing rod. A through hole is opened at the center position of the support plate. The rotating seat is installed in the through hole and can rotate relative to the support plate. The screw is welded to the top of the rotating seat. The threaded sleeve is threaded to the outside of the screw. One end of the insert rod assembly is installed on the side of the threaded sleeve via a rotating shaft. The guide hole group obliquely penetrates the support plate and the main body of the lower embedded fixing rod, and the other end of the insert rod assembly is inserted into the guide hole group.

[0008] Preferably, the insertion rod assembly includes a transmission rod and a lateral insertion rod. One end of the transmission rod is connected to the side of the threaded sleeve plate via a rotating shaft, and the other end of the lateral insertion rod is connected to one end of the transmission rod via a rotating shaft. The other end of the lateral insertion rod is inserted into the guide hole assembly.

[0009] Preferably, the guide hole group includes a first guide hole and a second guide hole. The first guide hole is opened on the side of the support plate, and the second guide hole is opened at the middle position of the side of the connecting threaded sleeve. A guide channel is formed between the first guide hole and the second guide hole, and the other end of the lateral insertion rod is inserted into the guide channel.

[0010] Preferably, the top of the screw is flush with the top of the connecting threaded sleeve, and the top end of the screw is hexagonal for engaging with an external ratchet.

[0011] Preferably, the end of the lateral insertion rod is flush with the outer wall of the lower embedded fixing rod body, and the lateral insertion rod has a configuration that is narrow at the bottom and wide at the top.

[0012] Preferably, the lowered auxiliary sleeve assembly includes a sleeve body, positioning holes, and a fixing rod. The sleeve body is sleeved outside the connecting threaded sleeve, and several sets of positioning holes are equally spaced in the edge of the sleeve body. The fixing rod is inserted into the positioning hole.

[0013] Preferably, the inner diameter of the sleeve body is the same as the outer diameter of the connecting threaded sleeve, and the length of the sleeve body is the same as the length of the screw.

[0014] The method for using GNSS-based slope deformation monitoring equipment includes the following steps:

[0015] Step S1: Align the main body of the sleeve vertically with the center of the point, apply downward pressure to completely bury the lower part of the sleeve body in the soil layer, and then slowly pull the sleeve body upward to bring out the internal soil core using the hollow structure of the sleeve body.

[0016] Step S2: Clean the hole formed after pulling out the sleeve, remove the residual soil in the hole to ensure that the inner wall of the hole is regular, and vertically insert the sleeve body into the repaired hole again. According to the compaction of the soil layer on site, select an appropriate number of positioning holes from several sets of positioning holes opened at equal intervals along the edge of the sleeve body, and insert the fixing rods one by one into the selected positioning holes. Through the friction between the fixing rods and the soil layer and the limiting effect of the positioning holes on the sleeve body, the sleeve body is stably fixed in the hole, and the deployment of the buried auxiliary sleeve group is completed.

[0017] Step S3: Align the main body of the buried fixing rod vertically with the hollow channel of the sleeve rod body fixed in step S, and slowly press the main body of the buried fixing rod downwards so that the lower part of the main body of the buried fixing rod gradually penetrates into the sleeve rod body and extends further into the soil layer below, until the top of the main body of the buried fixing rod is flush with the top of the sleeve rod body.

[0018] Step S4: At this time, the lower part of the buried fixing rod body is restricted by the soil layer, and the upper part of the buried fixing rod body is limited by the sleeve rod body, thus initially achieving position fixation, and the connecting threaded sleeve is exposed at the top of the sleeve rod body;

[0019] Step S5: Prepare an external wrench that fits the hexagonal shape at the top of the screw. Attach the wrench to the top of the screw in the auxiliary fixing assembly. Rotate the wrench to make the screw rotate relative to the support plate with the rotating seat. Since the threaded sleeve is threadedly connected to the screw, the screw rotates and drives the threaded sleeve to move downward along the screw axis.

[0020] In step S6, during the downward movement of the threaded sleeve, pressure is applied downward to the side transmission rod, which transmits the downward pressure to the side insertion rod, pushing the side insertion rod to extend out of the main body of the buried fixing rod along the guide channel at an angle until the transmission rod changes from an inclined state to a straight state. At this time, the side insertion rod reaches the maximum extension distance and penetrates the soil layers on both sides of the main body of the buried fixing rod, forming lateral support through the friction with the dense soil layer.

[0021] Step S7: Align the bottom of the main rod with the connecting threaded sleeve, and rotate the main rod to make the main rod and the threaded sleeve fit tightly with the main body of the lower fixed rod.

[0022] Step S8: Check the installation status of the bracket on the outside of the main pole. After confirming that everything is correct, fix the solar panel to one side of the bracket with bolts and fix the system box to the other side of the bracket. Finally, install the GNSS equipment at the top of the main pole. According to the circuit connection requirements, complete the electrical connection between the GNSS equipment and the bracket, and the electrical connection between the solar panel and the system box. Ensure that the solar panel can supply power to the system box and the system box can provide working power to the GNSS equipment. This completes the installation of the entire GNSS slope monitoring equipment, and the equipment enters the monitoring standby state.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] 1. This invention achieves rapid installation through the cooperation of the buried auxiliary sleeve rod assembly and the buried fixed rod assembly. Compared with the existing technology of cement platform pouring, which requires excavation of foundation pits, transportation of concrete materials and waiting for curing, the sleeve rod body can be pre-drilled and the soil layer cleaned. The buried fixed rod body is directly inserted into the hole and quickly connected to the main rod through the connecting threaded sleeve. There is no need for complicated material transportation and long-term curing. At the same time, the auxiliary fixing component only needs to turn the screw with an external wrench to drive the lateral insertion rod to complete the lateral fixing. The entire installation process does not require professional pouring equipment, the deployment cycle of a single point is greatly shortened, and there is no need to excavate the foundation.

[0025] 2. In this invention, the main body of the buried fixing rod is directly buried in the soil layer, and the lateral insertion rod of the auxiliary fixing component is obliquely inserted into the surrounding soil layer and closely adheres to the soil body, without a rigid isolation layer of cement platform; when the slope soil undergoes millimeter-level minute displacement, the displacement can be synchronously transmitted to the GNSS equipment at the top of the main rod through the main body of the buried fixing rod and the lateral insertion rod, ensuring that the equipment captures the early warning signal of slope instability and avoiding the loss of monitoring accuracy due to rigidity.

[0026] 3. In this invention, when the lateral insertion rod reaches its maximum protrusion distance, it simultaneously has lateral and vertical displacement limiting functions, thereby further ensuring the stability of the buried fixing rod group. In soft soil, by increasing the number of insertion rod assemblies on the side of the threaded sleeve plate, after the lateral insertion rods in each set of insertion rod assemblies are completely removed, each set of insertion rods can cooperate to form a near-cylindrical confined soil body outside the main body of the buried fixing rod, constituting a cylindrical bearing mode, thereby obtaining a larger deformation shear surface and further improving the stability of the installation.

Detailed Implementation

[0035] The present invention will be further described below with reference to the accompanying drawings and embodiments, which illustrate the above and other technical features and advantages of the present invention. However, the following embodiments are merely preferred embodiments of the present invention and are not exhaustive.

[0036] Example:

[0037] like Figures 1-6 As shown, the present invention provides a GNSS-based slope deformation monitoring device, including a main pole 1, a bracket 2 is provided on the outer side of the top of the main pole 1, a solar panel 3 and a system box 4 are respectively fixed to both sides of the bracket 2 by bolts, a GNSS device 5 is provided at the top of the main pole 1, the GNSS device 5 is electrically connected to the bracket 2, and the solar panel 3 is electrically connected to the system box 4. The device is characterized in that a buried fixing rod group 6 is installed at the bottom of the main pole 1, an auxiliary fixing component 7 is installed inside the buried fixing rod group 6, and a buried auxiliary sleeve rod group 8 is provided on the outside of the buried fixing rod group 6 to assist in fixing the buried fixing rod group 6.

[0038] The embedded fixing rod assembly 6 includes an embedded fixing rod body 61 and a connecting threaded sleeve 62;

[0039] The main body 61 of the buried fixing rod is buried in the soil layer, and the connecting threaded sleeve 62 is welded to the top of the main body 61. The connecting threaded sleeve 62 is used to connect with the bottom of the main rod 1 by thread. When installing the equipment, the main body 61 of the buried fixing rod is first pressed down and completely buried in the soil layer at the setting point. At this time, the main body 61 of the buried fixing rod, as the buried section, maintains the stability of the setting state through the friction with the soil layer. The connecting threaded sleeve 62, as the foundation for connecting with the main rod 1, is exposed outside the soil layer. The main rod 1 is then connected to the connecting threaded sleeve 62 by thread to complete the installation of the equipment.

[0040] The auxiliary fixing assembly 7 includes a support plate 71, a rotating seat 72, a screw 73, a threaded sleeve 74, a rod assembly 75, and a guide hole assembly 76;

[0041] The support plate 71 is welded to the middle position inside the lower embedded fixing rod body 61. A through hole is opened at the center position of the support plate 71. The rotating seat 72 is installed in the through hole and can rotate relative to the support plate 71. The screw 73 is welded to the top of the rotating seat 72. The threaded sleeve 74 is threaded to the outside of the screw 73. One end of the insertion rod assembly 75 is installed on the side of the threaded sleeve 74 through the rotating shaft. The guide hole group 76 obliquely penetrates the support plate 71 and the lower embedded fixing rod body 61. The other end of the insertion rod assembly 75 is inserted into the guide hole group 76.

[0042] After the main body 61 of the buried fixing rod is installed, the screw 73 is continuously rotated. During the rotation, the screw 73 drives the threaded sleeve 74 to move downward along the screw 73 through the threaded connection with the threaded sleeve 74. During the movement of the threaded sleeve 74, the threaded sleeve 74 continuously applies downward pressure to the insertion rod assemblies 75 on both sides of itself. During the pressure process, the insertion rod assemblies 75 are restricted by the guide hole group 76 and gradually tilt out from the inside of the main body 61 of the buried fixing rod, and insert into the soil layer on both sides of the main body 61 of the buried fixing rod. The insertion rod assemblies 75 obtain stable lateral support through the friction with the soil layer.

[0043] The insertion rod assembly 75 includes a transmission rod 751 and a lateral insertion rod 752;

[0044] One end of the transmission rod 751 is connected to the side of the threaded sleeve plate 74 via a rotating shaft, and the other end of the lateral insertion rod 752 is connected to one end of the transmission rod 751 via a rotating shaft. The other end of the lateral insertion rod 752 is inserted into the guide hole group 76.

[0045] During the downward movement of the threaded sleeve 74, the lateral insertion rod 752 maintains a fixed orientation under the constraint of the guide hole group 76. Therefore, as the threaded sleeve 74 gradually moves downward, the transmission rod 751 transmits the downward pressure it receives to the lateral insertion rod 752. Under the push of the transmission rod 751, the lateral insertion rod 752 gradually extends downward along the guide hole group 76 and is embedded outside the fixed rod body 61. As the lateral insertion rod 752 gradually extends outward, the transmission rod 751 gradually changes from an inclined state to a straight state. When the transmission rod 751 is completely straight, the lateral insertion rod 752 reaches its maximum extension distance. At this time, the lateral insertion rod 752 has both lateral and vertical displacement constraints.

[0046] In soft soil layers, the number of insert rod assemblies 75 on the side of the threaded sleeve plate 74 can be increased. After the lateral insert rods 752 in each set of insert rod assemblies 75 are completely removed, each set of insert rods 752 can cooperate to form a near-cylindrical confined soil body outside the buried fixing rod body 61, forming a cylindrical bearing mode, thereby obtaining a larger deformation shear surface and further improving the stability of the installation.

[0047] The guide hole assembly 76 includes a first guide hole 761 and a second guide hole 762.

[0048] The first guide hole 761 is opened on the side of the support plate 71, and the second guide hole 762 is opened at the middle position of the side of the connecting threaded sleeve 62. A guide channel is formed between the first guide hole 761 and the second guide hole 762, and the other end of the lateral insertion rod 752 is inserted into the guide channel.

[0049] During the downward movement of the lateral insertion rod 752, the guide channel restricts the deflection of the transmission rod 751, so that the transmission rod 751 always maintains a fixed tilt angle to ensure that the transmission rod 751 will not tilt. The transmission rod 751 can continuously apply downward pressure to the lateral insertion rod 752.

[0050] The top of the screw 73 is flush with the top of the connecting threaded sleeve 62. The top of the screw 73 is hexagonal for engaging with an external ratchet. When the screw 73 is rotated, the hexagonal top of the screw 73 can be used to connect with external wrenches or other equipment to facilitate rotation of the screw 73 from the outside.

[0051] The end of the lateral insertion rod 752 is flush with the outer wall of the lower-embedded fixing rod body 61. The lateral insertion rod 752 has a narrow bottom and wide top configuration. During the process of the connecting threaded sleeve 62 being inserted downward into the soil layer, the lateral insertion rod 752 can seal the second guide hole 762, preventing loose soil from falling into the lower-embedded fixing rod body 61 through the second guide hole 762. At the same time, as the lateral insertion rod 752 is gradually inserted into the soil layer, the lateral insertion rod 752 will continuously push the soil layer to compress and compact it outward. The lateral insertion rod 752 can obtain stable friction by closely adhering to the compacted soil layer.

[0052] The lowered auxiliary sleeve assembly 8 includes a sleeve body 81, a positioning hole 82, and a fixing insert 83;

[0053] The sleeve body 81 is fitted onto the outside of the connecting threaded sleeve 62. Several sets of positioning holes 82 are equally spaced along the edge of the sleeve body 81. The fixing rod 83 is inserted into the positioning holes 82. Before installing the buried fixing rod body 61, the sleeve body 81 is first inserted into the selected area. After the lower part of the sleeve body 81 is completely inserted into the soil layer, the sleeve body 81 is gradually pulled out. During the pulling out process, the internal soil core of the sleeve body 81 is brought out. The resulting hole is further cleaned and repaired until there is no remaining soil in the hole. The sleeve body 81 is then inserted into the hole again, and the fixing rods are then inserted in sequence. Insert 83 into the positioning hole 82. With the help of friction and the positioning hole 82, the sleeve rod body 81 is stably fixed in the formed hole. Then, insert the lower fixing rod body 61 into the sleeve rod body 81. The lower part of the lower fixing rod body 61 is inserted into the soil layer and is restricted by the soil layer. When the top of the lower fixing rod body 61 is flush with the top of the sleeve rod body 81, the lower fixing rod body 61 reaches the maximum setting position. At this time, after the auxiliary fixing component 7 is set, the main rod 1 can be connected to the lower fixing rod body 61 through the connecting threaded sleeve 62.

[0054] The inner diameter of the sleeve body 81 is the same as the outer diameter of the connecting threaded sleeve 62, and the length of the sleeve body 81 is the same as the length of the screw 73.

[0055] When the main body 61 of the buried fixing rod is inserted into the body 81 of the sleeve rod, the sleeve rod body 81, which is fixed by the friction of the soil layer, restricts the upper part of the main body 61 of the buried fixing rod, and the soil layer restricts the lower part of the main body 61 of the buried fixing rod. During the process of the sleeve rod body 81 being inserted into the soil layer and forming a hole, the formed hole can be used to accommodate the auxiliary fixing component 7, thereby ensuring the normal downward pressure and fixation of the main body 61 of the buried fixing rod.

[0056] Instructions for using GNSS slope monitoring equipment:

[0057] Align the main body 81 of the sleeve vertically with the center of the point, apply downward pressure to completely bury the lower part of the main body 81 of the sleeve into the soil layer, and then slowly pull out the main body 81 of the sleeve upward, using the hollow structure of the main body 81 of the sleeve to bring out the internal soil core.

[0058] The hole formed after extraction is cleaned to remove residual soil to ensure the inner wall of the hole is regular. The sleeve body 81 is then vertically inserted into the cleaned hole. According to the compaction of the soil layer, a suitable number of positioning holes 82 are selected from several sets of positioning holes 82 that are equally spaced along the edge of the sleeve body 81. The fixing rods 83 are inserted one by one into the selected positioning holes 82. Through the friction between the fixing rods 83 and the soil layer and the limiting effect of the positioning holes 82 on the sleeve body 81, the sleeve body 81 is stably fixed in the hole, completing the deployment of the buried auxiliary sleeve group 8.

[0059] Align the lower fixed rod body 61 vertically with the hollow channel of the sleeve rod body 81 fixed in step S1, and slowly press the lower fixed rod body 61 downwards so that the lower part of the lower fixed rod body 61 gradually penetrates into the sleeve rod body 81 and extends further into the soil layer below, until the top of the lower fixed rod body 61 is flush with the top of the sleeve rod body 81.

[0060] At this time, the lower part of the buried fixing rod body 61 is restricted by the soil layer, and the upper part of the buried fixing rod body 61 is limited by the sleeve rod body 81, thus initially achieving position fixation, and the connecting threaded sleeve 62 is exposed at the top of the sleeve rod body 81.

[0061] Prepare an external wrench that fits the hexagonal shape at the top of the screw 73. Attach the wrench to the top of the screw 73 in the auxiliary fixing assembly 7. Rotate the wrench to make the screw 73 rotate relative to the support plate 71 with the rotating seat 72. Since the threaded sleeve 74 is threadedly connected to the screw 73, the screw 73 rotates, driving the threaded sleeve 74 to move downwards along the axial direction of the screw 73.

[0062] During the downward movement of the threaded sleeve 74, downward pressure is applied to the side transmission rod 751. The transmission rod 751 transmits the downward pressure to the side insertion rod 752, pushing the side insertion rod 752 to extend outward along the guide channel to the outside of the buried fixing rod body 61. This continues until the transmission rod 751 changes from an inclined state to a straight state. At this point, the side insertion rod 752 reaches its maximum extension distance and penetrates the soil layers on both sides of the buried fixing rod body 61, forming lateral support through friction with the dense soil layer.

[0063] Align the bottom of the main rod 1 with the connecting threaded sleeve 62, and rotate the main rod 1 so that the main rod 1 is tightly connected to the lower embedded fixed rod body 61 through the threaded sleeve 62.

[0064] After checking the installation status of the bracket 2 on the outside of the top of the main pole 1 and confirming that everything is correct, fix the solar panel 3 to one side of the bracket 2 with bolts, and fix the system box 4 to the other side of the bracket 2. Finally, install the GNSS device 5 at the top of the main pole 1. According to the circuit connection requirements, complete the electrical connection between the GNSS device 5 and the bracket 2, and the electrical connection between the solar panel 3 and the system box 4, to ensure that the solar panel 3 can supply power to the system box 4 and the system box 4 can provide working power to the GNSS device 5. At this point, the installation of the entire GNSS slope monitoring equipment is completed, and the equipment enters the monitoring standby state.

[0065] The above description is merely a preferred embodiment of the present invention and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present invention, all of which will fall within the protection scope of the present invention.

Through the friction between the fixing rods (83) and the soil layer and the limiting effect of the positioning holes (82) on the sleeve body (81), the sleeve body (81) is stably fixed in the hole, and the deployment of the buried auxiliary sleeve group (8) is completed. Step S3: Align the lower fixed rod body (61) vertically with the hollow channel of the sleeve rod body (81) fixed in step S1, and slowly press the lower fixed rod body (61) downwards so that the lower part of the lower fixed rod body (61) gradually penetrates into the sleeve rod body (81) and extends further into the soil layer below, until the top of the lower fixed rod body (61) is flush with the top of the sleeve rod body (81); Step S4: At this time, the lower part of the buried fixing rod body (61) is restricted by the soil layer, and the upper part of the buried fixing rod body (61) is limited by the sleeve rod body (81), thus initially achieving position fixation. The connecting threaded sleeve (62) is exposed at the top of the sleeve rod body (81). Step S5: Prepare an external wrench that fits the hexagonal shape at the top of the screw (73), engage the wrench at the top of the screw (73) in the auxiliary fixing assembly (7), and rotate the wrench to make the screw (73) rotate relative to the support plate (71) with the rotating seat (72). Since the threaded sleeve (74) is threadedly connected to the screw (73), when the screw (73) rotates, it drives the threaded sleeve (74) to move downward along the axial direction of the screw (73). In step S6, during the downward movement of the threaded sleeve (74), pressure is applied downward to the side transmission rod (751). The transmission rod (751) transmits the downward pressure to the side insertion rod (752), pushing the side insertion rod (752) to extend outward from the outside of the buried fixing rod body (61) along the guide channel at an angle until the transmission rod (751) changes from an inclined state to a straight state. At this time, the side insertion rod (752) reaches the maximum extension distance and penetrates into the soil layers on both sides of the buried fixing rod body (61), forming lateral support through the friction with the dense soil layer. Step S7: Align the bottom of the main rod (1) with the connecting threaded sleeve (62), and rotate the main rod (1) so that the main rod (1) is tightly connected to the lower fixed rod body (61) through the threaded sleeve (62); Step S8: Check the installation status of the bracket (2) on the outside of the top of the main pole (1). After confirming that there are no errors, fix the solar panel (3) to one side of the bracket (2) with bolts, fix the system box (4) to the other side of the bracket (2), and finally install the GNSS device (5) on the top of the main pole (1). According to the circuit connection requirements, complete the electrical connection between the GNSS device (5) and the bracket (2) and the electrical connection between the solar panel (3) and the system box (4) to ensure that the solar panel (3) can supply power to the system box (4) and the system box (4) can provide working power to the GNSS device (5). The installation of the entire GNSS slope monitoring equipment is now complete, and the equipment enters the monitoring standby state.
