Description

Technical Field

[0001] This utility model relates to the field of roadbed settlement observation technology, and in particular to a roadbed settlement observation structure. Background Technology

[0002] In the field of road construction, the stability and safety of the roadbed directly affect the long-term performance of the road and the safety of traffic. Roadbed settlement is a crucial indicator of roadbed stability, making accurate and continuous monitoring of it essential.

[0003] Traditional roadbed settlement monitoring panels typically consist of three parts: a steel plate base, a metal measuring rod, and a plastic sleeve. In practical applications, the metal measuring rod and steel plate are permanently rigidly connected by welding, and the entire structure is then embedded in the roadbed soil. Each time settlement monitoring is conducted, surveyors need to erect a ruler above the metal measuring rod and then use specialized instruments to carry out the measurements. This process is not only cumbersome, but also, because the metal measuring rod and steel plate are permanently embedded in the soil, they cannot be reused. Whenever a new road project is undertaken or monitoring is conducted on different road sections, new monitoring panels need to be fabricated and embedded, resulting in significant material waste. Utility Model Content

[0004] The purpose of this invention is to provide a roadbed settlement observation structure to solve the problem that existing roadbed settlement observation boards cannot be reused.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A roadbed settlement monitoring structure includes: a first sleeve, a second sleeve, and a piston, wherein the first sleeve and the second sleeve are detachably connected; the piston is installed inside the first sleeve; a base plate and a first connecting rope, wherein the base plate abuts against the bottom of the second sleeve, the first connecting rope passes through the first sleeve and the second sleeve, and one end of the first connecting rope is connected to the base plate, and the other end is connected to the piston; the base plate and part of the second sleeve are used to be buried in the roadbed, and when the roadbed settles, the piston can descend along with the sinking of the base plate.

[0006] According to the above-mentioned technical means, in this utility model, the bottom plate and part of the second sleeve are buried in the roadbed. When the roadbed settles, the bottom plate sinks synchronously with the soil, while the second sleeve maintains a stable position by controlling the burial depth. One end of the first connecting rope is fixed to the bottom plate, and the other end is connected to a piston. The vertical displacement of the piston in the first sleeve is precisely equal to the settlement of the bottom plate, realizing direct and linear measurement of structural elevation changes.

[0007] The first and second sleeves adopt a detachable connection structure, and the sleeve assembly can be disassembled and recycled after construction. Compared with traditional permanent welded observation plates, this utility model realizes the reuse of core components such as the first sleeve, the second sleeve, and the piston, reducing the consumption of steel and plastics, and lowering the material costs for new projects or monitoring different road sections.

[0008] Furthermore, it also includes a secondary cylinder, the bottom of which is connected to the bottom of the first sleeve; the first sleeve stores lubricating fluid, the size of the piston is adapted to the internal size of the first sleeve, and during the piston's descent, the lubricating fluid in the first sleeve can be squeezed into the secondary cylinder.

[0009] According to the above technical means, the auxiliary cylinder and the bottom of the first sleeve are connected to form a communicating vessel structure. When the piston sinks and descends with the bottom plate, the lubricating fluid in the main sleeve is squeezed into the auxiliary cylinder.

[0010] Furthermore, it also includes a water-stop ring; a first through hole is formed at the bottom of the first sleeve, and the first connecting rope passes through the first through hole and connects to the bottom plate at the bottom of the second sleeve; the water-stop ring is installed between the first through hole and the first connecting rope to seal the gap between the first through hole and the first connecting rope.

[0011] Based on the above-mentioned technical means, this utility model achieves a precise seal between the first through hole and the first connecting rope by adding a water-stop ring.

[0012] Furthermore, the first sleeve has graduations formed on its side wall along the height direction.

[0013] Based on the above technical means, the scale is evenly distributed along the height direction of the first sleeve. During measurement, it is only necessary to directly observe the scale value corresponding to the piston edge to obtain the settlement of the base plate in real time, without the need to set up external rulers or complex instruments for leveling.

[0014] Furthermore, it also includes multiple rope clips, each of which is mounted on the piston, and the end of the first connecting rope is detachably mounted on the piston via one of the rope clips.

[0015] Based on the above technical means, the rope clip, as a special fastener, can achieve a stable fixation of the end of the first connecting rope through mechanical interlocking or buckle design, effectively preventing the first connecting rope from accidentally falling off due to external force.

[0016] Furthermore, each of the rope clips includes a mounting base and a fastener. The mounting base is fixed to the piston. A second through hole is formed on the mounting base along a first direction, and the second through hole is used to pass through the end of the first connecting rope. A third through hole is also formed on the mounting base along a second direction. The third through hole communicates with the second through hole and is used to pass through the fastener so that the fastener can tightly abut the end of the first connecting rope against the mounting base.

[0017] Based on the aforementioned technical means, the cross design of the third through hole and the second through hole allows the fastener to precisely tighten the end of the first connecting rope that passes through the second through hole via a second direction.

[0018] Furthermore, the fastener is a screw, and the third through hole is a threaded hole.

[0019] Based on the above technical means, the threaded fit has self-locking characteristics, which can effectively prevent fasteners from loosening under vibration or dynamic load environments.

[0020] Furthermore, it also includes a second connecting rope, the end of which is detachably mounted on the piston via a rope clamp, and the second connecting rope extends beyond the first sleeve.

[0021] According to the above-mentioned technical means, the second connecting rope can remove the piston from the first sleeve during the disassembly of the device.

[0022] Furthermore, it also includes a hook, and a hanging ring is formed on the base plate. The hook is installed at the end of the first connecting rope, and the end of the first connecting rope is connected to the hanging ring through the hook.

[0023] Based on the above-mentioned technical means, the connection and cooperation structure between the hook and the hanging ring enables the first connecting rope and the base plate to be quickly assembled and disassembled.

[0024] Furthermore, a connector tube is formed on the base plate, which is used to be inserted into the bottom of the second sleeve; the hanging ring is located inside the connector tube.

[0025] Based on the aforementioned technical means, the plug-in design between the connector tube and the bottom of the second sleeve enables rapid assembly. Operators only need to align the plug and push it in to complete the connection between the base plate and the second sleeve, eliminating the need for complex alignment or tool assistance, thus significantly reducing assembly time.

[0026] The beneficial effects achieved by this utility model are: In this invention, the base plate and part of the second sleeve are embedded in the roadbed. When the roadbed settles, the base plate sinks synchronously with the soil, while the second sleeve maintains a stable position through controlled embedment depth. One end of the first connecting rope is fixed to the base plate, and the other end is connected to a piston. The vertical displacement of the piston in the first sleeve is precisely equal to the settlement of the base plate, achieving direct and linear measurement of structural elevation changes.

[0027] The first and second sleeves adopt a detachable connection structure, and the sleeve assembly can be disassembled and recycled after construction. Compared with traditional permanent welded observation plates, this utility model realizes the reuse of core components such as the first sleeve, the second sleeve, and the piston, reducing the consumption of steel and plastics, and lowering the material costs for new projects or monitoring different road sections.

[0031] It should be noted that, unless otherwise specified, the embodiments and technical features in the embodiments of this application can be combined with each other, and the detailed descriptions in the specific embodiments should be understood as explanations of the purpose of this application and should not be regarded as undue limitations on this application.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

[0033] In the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0034] In the embodiments of this application, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection through an intermediate medium.

[0035] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0036] The technical solution of this embodiment will be described in detail below with reference to the accompanying drawings.

[0037] like Figure 1 As shown, a roadbed settlement monitoring structure includes: a first sleeve 1, a second sleeve 2, and a piston 3, wherein the first sleeve 1 and the second sleeve 2 are detachably connected; the piston 3 is installed inside the first sleeve 1; a base plate 4 and a first connecting rope 5, wherein the base plate 4 abuts against the bottom of the second sleeve 2, and the first connecting rope 5 passes through the first sleeve 1 and the second sleeve 2, with one end of the first connecting rope 5 connected to the base plate 4 and the other end connected to the piston 3; the base plate 4 and part of the second sleeve 2 are used to be buried in the roadbed, and when the roadbed settles, the piston 3 can descend along with the sinking of the base plate 4.

[0038] In this embodiment, the base plate 4 and part of the second sleeve 2 are embedded in the roadbed. When the roadbed settles, the base plate 4 sinks synchronously with the soil, while the second sleeve 2 maintains a stable position through the control of the embedment depth. One end of the first connecting rope 5 is fixed to the base plate 4, and the other end is connected to the piston 3. The vertical displacement of the piston 3 in the first sleeve 1 is precisely equal to the settlement of the base plate 4, realizing direct and linear measurement of structural elevation changes.

[0039] The first sleeve 1 and the second sleeve 2 adopt a detachable connection structure (such as threaded locking or snap-fit ​​connection), and the sleeve assembly can be disassembled and recycled after construction. Compared with the traditional permanent welded observation plate, this utility model realizes the reuse of core components such as the first sleeve 1, the second sleeve 2, and the piston 3, reducing the consumption of steel and plastic, and lowering the material cost when monitoring new projects or different road sections.

[0040] like Figure 1 As shown, it also includes a secondary cylinder 6, the bottom of which is connected to the bottom of the first sleeve 1; the first sleeve 1 stores lubricating fluid, the size of the piston is adapted to the internal size of the first sleeve 1, and during the descent of the piston 3, the lubricating fluid in the first sleeve 1 can be squeezed into the secondary cylinder 6.

[0041] The auxiliary cylinder 6 is connected to the bottom of the first sleeve 1 to form a communicating vessel structure. When the piston 3 sinks and descends with the bottom plate 4, the lubricating fluid in the main sleeve is squeezed into the auxiliary cylinder 6.

[0042] Preferably, the outer periphery of the piston 3 and the inner wall of the first sleeve 1 are in a precision dynamic fit, and the fit clearance is sufficient to form a lubricating film to minimize frictional resistance while ensuring good sealing and preventing a large amount of lubricating fluid from leaking from the periphery of the piston 3.

[0043] Meanwhile, to prevent the piston 3 from tilting under long-term unilateral force (tension of the first connecting rope 5), which could cause greater friction or even jamming with the wall of the first sleeve 1, a guide ring can be added to the side wall of the piston 3.

[0044] Specifically, in this embodiment, the main body of piston 3 is made of rubber, which can be nitrile rubber (NBR) or fluororubber (FKM). The rubber piston 3 is chemically compatible with the selected lubricant (such as silicone oil). At least two guide rings (not shown in the figure) made of low-friction coefficient material (such as polytetrafluoroethylene PTFE) are embedded on the outside of the rubber piston 3. The guide rings are in contact with the inner wall of the first sleeve 1 to reduce friction and prevent piston deflection.

[0045] In this embodiment, the liquid storage function of the auxiliary cylinder 6, combined with the anti-evaporation design (such as low evaporation medium and sealing cover), significantly reduces the frequency of liquid replenishment and achieves long-term maintenance-free operation.

[0046] Piston 3 can be made of rubber. The corrosion resistance and aging resistance of the piston ensure that the device works stably in harsh environments such as high temperature, high humidity, and salt spray, reducing measurement errors caused by component aging and extending the entire life cycle of the equipment.

[0047] To prevent the lubricant in the first sleeve 1 from evaporating in an outdoor environment, this embodiment preferably includes: 1. The liquid in the first sleeve 1 can be a low vapor pressure liquid such as silicone oil or mineral oil. In the common roadbed ambient temperature range of -20℃ to 60℃, the evaporation rate is only less than 1 / 50 of that of water, which effectively avoids the problem of float position displacement and measurement reference distortion caused by water evaporation.

[0048] 2. The top of the first sleeve 1 is covered with a waterproof and breathable membrane (such as expanded polytetrafluoroethylene membrane). The waterproof and breathable membrane allows the air pressure inside and outside the sleeve to be balanced, preventing negative pressure collapse or positive pressure expansion caused by temperature changes, while also blocking moisture evaporation.

[0049] like Figure 1 As shown, it also includes a water-stop ring 7; as Figure 2 As shown, a first through hole 11 is formed at the bottom of the first sleeve 1, and the first connecting rope 5 passes through the first through hole 11 and connects to the bottom plate 4 at the bottom of the second sleeve 2; a water-stop ring 7 is installed between the first through hole 11 and the first connecting rope 5 to seal the gap between the first through hole 11 and the first connecting rope 5.

[0050] In this embodiment, a water-stop ring 7 is added to achieve a precise seal between the first through hole 11 and the first connecting rope 5.

[0051] In this embodiment, the water-stop ring 7 is made of highly elastic rubber or silicone material, which fits tightly against the outer wall of the first connecting rope 5 and the inner wall of the first through hole 11 to form a dynamic sealing barrier, effectively preventing the lubricant in the first sleeve 1 from leaking through the gap.

[0052] To prevent lubricant leakage due to wear of the water-stop ring 7, in this embodiment, the water-stop ring 7 can be made of wear-resistant, highly elastic polyurethane (PU) or fluororubber (FKM) material.

[0053] like Figure 1 As shown, the first sleeve 1 has a scale 12 formed on its side wall along the height direction.

[0054] The scale 12 is evenly distributed along the height direction of the first sleeve 1. During measurement, it is only necessary to directly observe the scale value corresponding to the edge of the piston 3 to obtain the settlement of the base plate 4 in real time, without the need to set up an external ruler or complex instruments for leveling.

[0055] In this embodiment, the graduation 12 can be made by laser engraving or ceramic coating, which has high wear resistance and corrosion resistance, and can still maintain clear and distinguishable graduations under long-term sunlight, rain erosion or temperature difference.

[0056] In this embodiment, an observation window (not shown in the figure) is formed on the side wall of the first sleeve 1. The observation window is arranged along the height direction of the first sleeve 1 and is located next to the scale 12. The observation window can be made of a high light transmittance material (such as tempered glass or weather-resistant polycarbonate), allowing direct observation of the real-time position of the piston 3 inside the first sleeve 1. Measurement can be performed without opening the sleeve or disassembling components, avoiding the risk of liquid leakage and the intrusion of external impurities.

[0057] like Figure 1 As shown, it also includes multiple rope clips 8, each rope clip 8 is mounted on the piston 3, and the end of the first connecting rope 5 is detachably mounted on the piston 3 via a rope clip 8.

[0058] The rope clip 8, as a special fastener, can securely fix the end of the first connecting rope 5 through mechanical interlocking or buckle design, effectively preventing the first connecting rope 5 from accidentally falling off due to external force.

[0059] like Figure 3 and Figure 4 As shown, each rope clip 8 includes a mounting base 81 and a fastener 82. The mounting base 81 is fixed on the piston 3. A second through hole 811 is formed on the mounting base 81 along a first direction. The second through hole 811 is used to pass through the end of the first connecting rope 5. A third through hole (not shown in the figure) is also formed on the mounting base 81 along a second direction. The third through hole (not shown in the figure) is connected to the second through hole 811. The third through hole (not shown in the figure) is used to pass through the fastener 82 so that the fastener 82 can tightly abut the end of the first connecting rope 5 against the mounting base 81.

[0060] The intersection design of the third through hole (not shown in the figure) and the second through hole 811 allows the fastener 82 to precisely press the end of the first connecting rope 5 that passes through the second through hole 811 in a second direction.

[0061] In this embodiment, as Figure 3 and Figure 4 As shown, the first direction and the second direction are perpendicular to each other.

[0062] Preferably, the mounting base 81 can be made of corrosion-resistant alloy or polymer composite material, forming a protective combination with the fastener 82 that is resistant to salt spray and ultraviolet radiation.

[0063] like Figure 4 As shown, fastener 82 is a screw, and the third through hole (not shown in the figure) is a threaded hole.

[0064] The threaded fit has a self-locking property, which can effectively prevent fastener 82 from loosening under vibration or dynamic load environment.

[0065] In this embodiment, as Figure 4 As shown, a handle is formed on the fastener 82, allowing the operator to directly rotate the screw by hand using the handle, so that the installation / disassembly process does not require additional tools.

[0066] like Figure 1 As shown, it also includes a second connecting rope 9, the end of which is detachably mounted on the piston 3 via a rope clip 8, and the second connecting rope 9 extends to the outside of the first sleeve 1.

[0067] The second connecting rope 9 can remove the piston 3 from the first sleeve 1 during the disassembly of the device.

[0068] like Figure 1 As shown, it also includes a hook 10, and a hanging ring 41 is formed on the base plate 4. The hook 10 is installed at the end of the first connecting rope 5, and the end of the first connecting rope 5 is connected to the hanging ring 41 through the hook 10.

[0069] The connection structure between the hook 10 and the hanging ring 41 allows the first connecting rope 5 and the base plate 4 to be quickly assembled and disassembled.

[0070] In this embodiment, the hook 10 is made of high-strength alloy material and combined with the reinforcing rib structure design of the hanging ring 41, it can withstand large tensile force without deformation or breakage.

[0071] like Figure 1 As shown, a connector tube 42 is also formed on the base plate 4, which is used to be inserted into the bottom of the second sleeve 2; the hanging ring 41 is located inside the connector tube 42.

[0072] The plug-in design of the connector tube 42 and the bottom of the second sleeve 2 enables rapid assembly. The operator only needs to align the plug and push it in to complete the connection between the base plate 4 and the second sleeve 2, without the need for complicated alignment or tool assistance, which significantly shortens the assembly time.

[0073] The sequence numbers of the embodiments in this application are for descriptive purposes only and do not represent the superiority or inferiority of the embodiments. The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made based on the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
