Abstract

This utility model relates to an assembled integrated inclinometer for monitoring deep slope displacement, comprising an inclinometer tube and an inclinometer. The inclinometer tube is a multi-segment assembled structure with a closed bottom and an open top for easy insertion of the inclinometer. The inclinometer includes a main column with a connecting fastener at its top, which is threaded to the inner wall of the inclinometer tube. This utility model uses a multi-segment assembled inclinometer tube, with the inclinometer tube threaded to the connecting fastener at the top of the inclinometer. This eliminates the need for the inclinometer tube diameter to be much larger than the inclinometer diameter, thus eliminating the need for drilling large-diameter inclinometer holes during construction and effectively reducing soil disturbance.

The closed bottom and threaded connection of the inclinometer tube to the inclinometer effectively isolates the inclinometer from the underground environment, effectively resisting the influence of complex underground environments and ensuring long-term stable operation of the inclinometer.

Description

Technical Field

[0001] This utility model relates to an assembled integrated inclinometer for monitoring deep displacement of slopes. Background Technology

[0002] In the field of intelligent slope monitoring, the technical solution for traditional fixed inclinometer devices used for deep slope displacement monitoring is usually as follows: First, inclinometer holes need to be drilled in the monitoring area. Then, PVC inclinometer tubes are placed into the inclinometer holes, and the bottom of the inclinometer holes is sealed with clay. After the inclinometer tubes are laid, the inclinometer is placed in the inclinometer tubes. A water-sealing plug needs to be installed at the lower end of the inclinometer to deal with the influence of moisture in the underground environment. The upper end of the inclinometer needs to be fixed. There are usually two fixing methods: one is to use a hole-mouth suspension device and fix it with two support bolts; the other is to fix the pipe opening by pouring concrete, but the latter construction procedure is more complicated.

[0003] However, the above-mentioned technical solutions for traditional fixed inclinometers have the following problems: (1) High risk of soil disturbance and insufficient monitoring accuracy: Because the diameter of the inclinometer tube is much larger than that of the inclinometer, a large diameter inclinometer hole needs to be opened during drilling. However, the slope monitoring objects are mostly dangerous slopes with poor stability and fragile soil. Large diameter drilling can easily cause significant disturbance to the slope soil, increasing the safety hazards of the slope. At the same time, excessive diameter deviation will lead to poor compatibility between the inclinometer tube and the inclinometer displacement. Even if extension devices such as guide wheels are used, there is still room for improvement in its compatibility. (2) The inclinometer has poor environmental adaptability for long-term operation: The traditional inclinometer tube is a hollow structure. Although the groundwater influence is mitigated by sealing the bottom with clay and installing a waterproof plug at the bottom of the inclinometer, the damp underground environment and other complex underground environmental factors can still affect the inside of the inclinometer tube, causing corrosion to the inclinometer that needs to be placed for a long time, which may lead to damage to the inclinometer and abnormal monitoring data. (3) The traditional method of fixing the upper end of the inclinometer has the following problems: the hole suspension device relies on the support bolts for fixing. This method requires the ground at the hole to be flat and hard, which cannot be adapted to the relatively soft soil environment of the slope surface. The method of fixing the pipe opening with concrete pouring is complicated in terms of construction procedures, which not only increases the construction cost, but also seriously affects the construction efficiency in the field environment. Utility Model Content

[0004] This utility model addresses the problems existing in the prior art by providing an assembled integrated inclinometer for monitoring deep displacement of slopes.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: an assembled integrated inclinometer for monitoring deep slope displacement, comprising an inclinometer tube and an inclinometer for installation inside the inclinometer tube. The inclinometer tube is a multi-segment assembled type, with a closed structure at the bottom and an opening at the top to facilitate the insertion of the inclinometer. The inclinometer includes an inclinometer main column, and a connecting fastener is provided at the top of the inclinometer main column. The connecting fastener is threadedly connected to the inner wall of the inclinometer tube.

[0006] Furthermore, the connecting fastener includes a cylindrical connecting fastener seat coaxially arranged with the main column of the inclinometer, and the outer wall of the connecting fastener seat is threadedly connected to the inner wall of the upper end of the inclinometer tube.

[0007] Furthermore, a hand-tightening operation block is provided at the top center of the connecting fixing seat, which facilitates manual rotation of the connecting fixing seat and the inclinometer main column.

[0008] Furthermore, the interior of the connecting fixing base is provided with a cable through hole that runs through its axial direction, the cable through hole facilitating the cable lead-out from the main column of the inclinometer.

[0009] Furthermore, the inclinometer tube includes multiple tubes for static pressure driving into the soil, with adjacent tubes connected by threads. The bottom of the tube at the bottom end has a closed structure, while the top of the tube at the top end has an open opening.

[0010] Furthermore, in addition to the tube at the bottom, each tube has an external thread on one end of its outer wall and an internal thread on the other end of its inner wall for engaging with the external thread; the inner wall at the top of the tube at the bottom is also provided with an internal thread for engaging with the external thread.

[0011] Furthermore, the outer surface of the connecting fixing seat is provided with an external connecting thread, which is used to cooperate with the internal thread on the inner wall of the upper end of the tube located at the top.

[0012] Furthermore, the main column of the inclinometer is composed of multiple spliced ​​sections.

[0013] Furthermore, the outer diameter of the main column of the inclinometer is the same as the outer diameter of the connecting fixing base.

[0014] Furthermore, PTFE tape is wrapped between the external thread and the internal thread, and between the external connecting thread and the internal thread.

[0015] Compared with the prior art, this utility model has the following advantages: The utility model has a reasonable structural design, adopts a multi-segment assembled inclinometer tube, and the inclinometer tube is connected to the top of the inclinometer by a threaded fastener, so that the diameter of the inclinometer tube does not need to be much larger than the diameter of the inclinometer, and there is no need to drill a large-diameter inclinometer hole during construction, which effectively reduces soil disturbance; at the same time, the threaded connection between the inclinometer tube and the inclinometer eliminates the need for bolts or concrete pouring, making it suitable for various slope soils; in addition, the bottom of the inclinometer tube is closed and the top is threadedly connected to the inclinometer, which effectively isolates the inclinometer from the underground environment, effectively resists the influence of complex underground environments, and ensures the long-term stable operation of the inclinometer.

Detailed Implementation

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0019] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] This utility model discloses an assembled integrated inclinometer for monitoring deep slope displacement. The technical problems it aims to solve include: First, how to reduce soil disturbance during the construction of the inclinometer while improving the displacement compatibility between the inclinometer tube and the inclinometer, thereby reducing slope safety hazards and improving monitoring accuracy; Second, how to optimize the structure and sealing performance of the inclinometer tube to effectively isolate the influence of groundwater and other complex underground environmental factors on the inclinometer, ensuring long-term stable operation of the inclinometer; Third, how to design an upper fixing structure for the inclinometer that adapts to the slope soil surface environment, simplifying the fixing process and avoiding reliance on flat, hard ground or cumbersome concrete pouring procedures, thereby improving adaptability and efficiency in field construction; Fourth, how to improve the portability of the inclinometer tube by optimizing its structural form to better adapt to the field construction environment and further reduce construction difficulty.

[0021] like Figures 1-7 As shown, this utility model discloses an assembled integrated inclinometer for monitoring deep slope displacement, comprising an inclinometer tube 1 and an inclinometer 2 for installation inside the inclinometer tube 1. The specific improvements are as follows: the inclinometer tube 1 is a multi-section assembled structure, allowing for disassembly and transport for improved portability; the bottom of the inclinometer tube 1 is a closed structure, while the top of the inclinometer tube 1 has an opening 11 to facilitate the insertion of the inclinometer; the inclinometer 2 includes an inclinometer main column 12, with no guide wheels on the outer side of the main column, and a connecting fastener 3 at the top of the main column 12. After the main column 12 extends into the inclinometer tube 1 through the opening 11 at the top, the connecting fastener 3 is threadedly connected to the inner wall of the inclinometer tube 1. The inclinometer uses a multi-segment assembled inclinometer tube, and the inclinometer tube is connected to the top of the inclinometer by a threaded fastener. This means that the diameter of the inclinometer tube does not need to be much larger than the diameter of the inclinometer, eliminating the need to drill large-diameter inclinometer holes during construction and effectively reducing soil disturbance. At the same time, the threaded connection between the inclinometer tube and the inclinometer eliminates the need for bolts or concrete pouring, making it suitable for various slope soil types. In addition, the closed bottom of the inclinometer tube and the threaded connection to the top of the inclinometer effectively isolate the inclinometer from the underground environment, effectively resisting the influence of complex underground environments and ensuring the long-term stable operation of the inclinometer.

[0022] In this embodiment, the connecting fastener 3 includes a cylindrical connecting fastener 4 coaxially arranged with the inclinometer main column 12. The outer wall of the connecting fastener 4 is threadedly connected to the inner wall of the upper end of the inclinometer tube 1. Furthermore, the outer diameter of the inclinometer main column 12 is the same as the outer diameter of the connecting fastener 4. Since the cylindrical connecting fastener is connected to the inner wall of the upper end of the inclinometer tube via threads, the outer diameter of the connecting fastener (i.e., the outer diameter of the inclinometer main column) matches the inner diameter of the inclinometer tube. Therefore, the diameter of the inclinometer tube is smaller, and the diameter of the inclinometer tube does not need to be much larger than the diameter of the inclinometer, eliminating the need to drill a large-diameter inclinometer hole during construction. Because the inner diameter of the test tube matches the outer diameter of the inclinometer, the dimensional deviation of the traditional inclinometer tube, where the "diameter is much larger than the diameter of the inclinometer," is eliminated. This reduces displacement transmission errors between the inclinometer tube and the inclinometer, directly improving monitoring accuracy. Furthermore, the reduced diameter significantly reduces disturbance to the slope soil during drilling, making it suitable for the fragile soil environment of dangerous slopes.

[0023] In this embodiment, in order to improve the convenience of operation, a hand-tightening operation block 5 is provided at the top center of the connecting fixing seat 4. The hand-tightening operation block 5 facilitates manual rotation of the connecting fixing seat 4 and the inclinometer main column 12.

[0024] In this embodiment, the connecting fixing base 4 has a cable through-hole 6 extending along its axial direction inside. The cable through-hole 6 facilitates the lead-out of the signal and power cables from the inclinometer main column 12. It should be noted that the cable leading out from the cable through-hole connects to IoT module devices such as data acquisition terminals and power supply equipment (the specific settings and security processes of IoT modules are not repeated in this embodiment due to their high level of technological maturity), ensuring the real-time transmission of monitoring data. These are all the same as the existing inclinometer structure, and their connection relationships and principles will not be repeated here.

[0025] In this embodiment, the inclinometer tube 1 includes multiple tubes 7 for static pressure driving into the soil. Adjacent tubes 7 are threaded together, with the bottom of the tube 7 at the bottom being a closed structure and the top of the tube 7 at the top having an opening 11. Specifically, except for the tube 7 at the bottom, each tube 7 has an external thread 8 on one end of its outer wall and an internal thread 9 on the other end of its inner wall for engaging with the external thread 8; the inner wall of the upper end of the tube 7 at the bottom also has an internal thread 9 for engaging with the external thread 8. The inclinometer tube adopts a segmented design, with each segment connected by threads. This connection structure ensures the coaxiality of adjacent tubes, avoiding the impact of connection deviations on the installation and displacement monitoring of the inclinometer, and also achieves sealing of the connection points through threaded engagement, preventing groundwater from seeping in through the gaps between segments. At the same time, the segmented design significantly reduces the weight and volume of a single segment of the inclinometer tube, improving the portability for field transportation and installation, and solving the problem of difficult field transportation of traditional whole inclinometer tubes. Furthermore, the test tubes are made of materials with excellent sealing and waterproof properties.

[0026] In this embodiment, since the bottom of the pipe is a closed structure, it is easy to block the channels for groundwater and ground moisture to enter the interior from the bottom of the inclinometer tube. Combined with the waterproof material of the entire inclinometer tube, a full-link sealing protection of "bottom-intersection-top" is formed, which solves the defect of insufficient sealing of traditional clay bottom sealing.

[0027] In this embodiment, the outer surface of the connecting fixing seat 4 is provided with an external connecting thread 10, which is used to mate with the internal thread 9 on the inner wall of the upper end of the tube 7 located at the top. During installation, simply screwing the connecting fixing seat at the top of the inclinometer into the thread at the top end of the inclinometer tube will achieve a stable fixation of the upper end of the inclinometer, without relying on traditional support bolts or concrete pouring, thus solving the problems of not being able to install bolts on the slope soil surface and the cumbersome concrete pouring process.

[0028] In this embodiment, in the inclinometer tube, PTFE tape is wrapped between the external thread 8 and the internal thread 9 between adjacent tube bodies 7, and between the external connecting thread 10 of the connecting fixing seat 4 and the internal thread 9 of the tube body 7, to improve the sealing effect of the threaded connection.

[0029] It should be noted that the inclinometer in this embodiment is an existing mature product. This embodiment is based on the existing inclinometer, but the external guide wheel is removed. At the same time, a threaded connecting and fixing seat is set on the top of the inclinometer. The structure and working principle of the inclinometer are the same as the existing products, and will not be repeated here.

[0030] In this embodiment, the construction process includes the following steps: 1. Construction preparation: Assembled inclinometer tube, portable static pressure drilling equipment (such as a portable hydraulic drilling machine, which must meet the requirements for small-diameter static pressure construction). 2. Segmented Driving of Inclinometer Tubes: Using a portable static pressure drilling device, the first tube section (i.e., the bottom tube with its closed end) is driven into the slope soil using static pressure. After the first tube section is fixed, PTFE tape is wrapped around the external threads of the first tube section. Then, the second tube section is connected to the first tube section through threads, and the static pressure device is used to continue driving it into the soil. PTFE tape is then wrapped around the external threads of the second tube section, and the third tube section is connected to the second tube section through threads, and the static pressure device is used to continue driving it into the soil. This process is repeated until all tubes are driven into the soil and the designed monitoring depth is reached. Because the inclinometer tube has a small borehole diameter (compatible with the inclinometer diameter) and a short single-section length, the compression and disturbance to the soil during static pressure driving is much less than that of traditional large-diameter drilling. Furthermore, there is no need to pre-drill inclinometer holes; the inclinometer tube itself serves as an integrated "drilling-support" structure, further simplifying the construction process. 3. Installation of the inclinometer and placement into the inclinometer hole: After the entire inclinometer tube is installed and driven into the soil, the inclinometer is placed into the inclinometer tube from the top opening (i.e., the tube opening). The connecting and fixing seat at the top of the inclinometer is screwed into the thread of the tube opening at the top of the inclinometer tube to achieve a stable fixation of the upper part of the inclinometer. 4. Connecting the IoT module device: Pass the signal cable through the cable hole of the connection mounting base on the top of the inclinometer and connect the IoT module device (including data acquisition terminal, functional equipment, IoT data transmission module, etc.) (The construction process for connecting the IoT module is relatively mature and will not be described here).

[0031] This construction process abandons the traditional procedure of "drilling a large-diameter inclinometer hole first and then laying the inclinometer tube." Instead, it uses portable static pressure equipment to directly drive the segmented inclinometer tube into the soil. The inclinometer tube itself has an integrated "drilling-support" function: the small-diameter hole and segmented static pressure driving method greatly reduces soil compression and disturbance, making it suitable for fragile soils on dangerous slopes. It eliminates the need for drilling and hole fixing, and eliminates the need for large drilling equipment, reducing the number of operators and significantly improving the convenience and efficiency of field construction, while saving construction costs.

[0032] In another embodiment, the main column of the inclinometer can be composed of multiple segments, with adjacent segments connected by connectors. It should be noted that the modular inclinometer is an existing product.

[0033] The advantages of this utility model are: (1) Significantly reduce soil disturbance and improve monitoring accuracy: Existing technologies require drilling large-diameter inclinometer holes because the diameter of the inclinometer tube is much larger than that of the inclinometer, which easily disturbs the fragile slope soil; and the size deviation leads to displacement transmission error, affecting accuracy. This utility model reduces the inclinometer tube diameter by "matching the inner diameter of the inclinometer tube with the outer diameter of the inclinometer", and combines it with the "segmented static pressure driving (no pre-drilling required)" process to significantly reduce soil extrusion disturbance; at the same time, it eliminates the large size gap between the inclinometer tube and the inclinometer, directly reducing displacement transmission error and improving monitoring accuracy; 2. End-to-end sealed protection enhances the inclinometer's environmental adaptability: Existing technologies rely on methods such as sealing the bottom with clay and installing waterproof plugs at the bottom of the inclinometer to reduce the impact of groundwater and other factors. However, the PVC pipes used in existing solutions have a perforated design, which cannot isolate underground moisture, groundwater, and other complex underground environments, making the inclinometer susceptible to damage during long-term operation in underground environments. This utility model, through an "assembled inclinometer tube end-to-end sealed design" (bottom fully sealed structure + inter-section threaded embedded seal), completely isolates the inclinometer from the underground environment, effectively resisting the influence of complex underground environments and ensuring the long-term stable operation of the inclinometer. 3. Adaptable to slope soil environment and simplified construction process: In existing technologies, if the upper end of the inclinometer is fixed with a bolt-on orifice suspension device, it requires a flat and hard ground (unsuitable for soft slopes). Concrete pouring for fixation is cumbersome and costly. This invention uses a "threaded connection and fixing seat on the top of the inclinometer," which only needs to be screwed onto the inclinometer tube opening for fixation, eliminating the need for bolts or concrete pouring, and is suitable for various slope soil types. Furthermore, the "segmented installation + static pressure driving" method eliminates the drilling process, allowing for completion with a portable static pressure machine, eliminating the need for drilling equipment on-site, reducing operator workload, minimizing soil disturbance, significantly improving field construction efficiency, and reducing construction costs. 4. Segmented design improves portability and reduces the difficulty of field construction: Existing technologies use long and heavy PVC inclinometer tubes, making them difficult to transport and install in the field. In this invention, the inclinometer tube adopts a segmented design, with each segment being lightweight and compact, making it easy to carry and transport in the field.

[0034] If this utility model discloses or relates to mutually fixedly connected parts or structural components, then, unless otherwise stated, a fixed connection can be understood as: a detachable fixed connection (e.g., using bolts or screws), or a non-detachable fixed connection (e.g., riveting, welding). Of course, mutually fixed connections can also be replaced by an integral structure (e.g., manufactured using a casting process) (except where it is obviously impossible to use an integral forming process).
