Description

Technical Field

[0001] A type of roadbed monitoring observation pile is used for roadbed settlement monitoring, belonging to the technical field of roadbed settlement observation piles. Background Technology

[0002] Roadbed monitoring and observation piles refer to roadbed settlement observation piles, which include settlement plates and observation rods. Settlement plates are prone to tilting during installation, or when the bottom of the settlement plate is placed on a weak foundation (such as silt or collapsible loess), the lateral extrusion force during the filling and rolling process will push the side wall of the settlement plate out of place, causing the settlement plate to tilt. The tilting of the settlement plate will directly lead to the tilting of the subsequent installation of the observation rod, which in turn will cause systematic data distortion.

[0003] When a settlement slab tilts, existing technology typically adjusts the tilt by reinstalling it, but this presents the following technical problems: 1. It causes significant secondary disturbance to the roadbed, and the secondary installation is also prone to re-tilting, making it difficult to guarantee the accuracy of the correction. 2. This greatly reduces construction efficiency and increases construction costs. Utility Model Content

[0004] The purpose of this invention is to provide a roadbed monitoring and observation pile that solves the problems of existing technologies causing large secondary disturbances to the roadbed and the tendency for secondary installation to cause further tilting, thus making it difficult to guarantee the accuracy of correction.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A roadbed monitoring observation pile includes a settlement plate, an initial rod set on the settlement plate, a support plate set on the settlement plate to support the initial rod, an observation rod movably set on the initial rod, the initial rod including an initial measuring rod and an initial sleeve set on the settlement plate, the observation rod including a measuring rod and a sleeve, and an adjustment structure for verticality adjustment movably set on the initial rod, the observation rod being installed on the initial rod through the adjustment structure; The adjustment structure includes a fixed structure threaded onto the initial rod, an adjustment plate with a connector rotatably mounted on the fixed structure, and an adjustment component mounted on the fixed structure to adjust the verticality of the adjustment plate. The observation rod mates with the connector on the adjustment plate.

[0006] Furthermore, the fixing structure includes a fixed sleeve with internal threads that mates with the initial sleeve thread, a support rod disposed on the fixed sleeve, and an annular sleeve disposed on the support rod.

[0007] Furthermore, the adjusting plate includes a plate body, a connecting rod disposed on the bottom of the plate body, a rotating ball disposed on the connecting rod and rotating in conjunction with the annular sleeve, and a connector disposed on the top surface of the plate body. The connector includes an inner connector disposed on the plate body with internal or external threads, an outer connector disposed on the plate body and fitted onto the inner connector with external threads, and a threaded sleeve with internal threads that mates with the outer connector. The measuring rod of the observation rod mates with the inner connector, and the sleeve mates with the threaded sleeve.

[0008] Furthermore, the adjusting component includes a plurality of L-shaped support rods arranged on the fixed sleeve along the circumference of the fixed sleeve. Each L-shaped support rod includes a horizontal rod connected to the fixed sleeve and a vertical threaded rod connected to the horizontal rod. An adjusting rod with an adjusting plate body parallel to the horizontal plane is threaded on the vertical threaded rod.

[0009] Furthermore, the adjusting rod is provided with a shim that contacts and engages with the plate.

[0010] Furthermore, the vertical threaded rod is also provided with a nut to limit the position of the adjusting rod.

[0011] Furthermore, the fixing sleeve includes a threaded fixing sleeve that mates with the initial sleeve thread, a protective sleeve disposed on the threaded fixing sleeve and fitted onto the initial measuring rod to support the initial measuring rod, and a mounting plate disposed on the protective sleeve to mount the support rod.

[0012] Compared with the prior art, the advantages of this utility model are: I. When the settlement plate tilts, this utility model installs an adjustment structure on the initial rod, fixes it to the initial rod through the fixing structure in the adjustment structure, adjusts the verticality of the connector on the adjustment plate (so that the connector is perpendicular to the horizontal plane) through the adjustment component, and then installs an observation rod on the connector. This effectively avoids secondary disturbance to the roadbed. The correction through the adjustment structure makes the correction accuracy high, and also improves construction efficiency and reduces construction costs. 2. The fixing structure in this utility model is fixed to the initial sleeve by a fixing sleeve, and a support rod is set on the fixing sleeve. An annular sleeve is set on the support frame. The structure is simple and it is convenient for the adjustment plate to be installed on the annular sleeve for rotation in order to adjust the verticality of the connector. Third, the adjusting plate in this utility model is connected to a rotating ball by a connecting rod under the plate body, which rotates inside the annular sleeve, so that the plate body can be adjusted to be parallel to the horizontal plane, that is, it is convenient to adjust the connecting head to be perpendicular to the horizontal plane. The structure is simple and easy to adjust. IV. The adjusting component of this utility model has an adjusting rod threaded on the vertical threaded rod of the L-shaped support rod, which makes it easy to limit the rotation of the plate by adjusting the height of the adjusting rod. Thus, the plate is kept parallel to the horizontal plane by the limiting effect of multiple adjusting rods at different positions. V. This utility model provides a shim on the adjusting rod, which increases the friction between the adjusting rod and the plate, preventing the plate from easily rotating horizontally. VI. The present invention provides a nut on the vertical threaded rod to further limit the adjustment rod, the purpose of which is to further ensure the stability of the plate after it is parallel to the horizontal plane; VII. In this utility model, the fixing sleeve is fixed to the initial sleeve by a threaded fixing sleeve and limited by a protective sleeve. Then, the support rod is installed by the mounting plate, which is convenient for fixing and facilitates fixing in place. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0022] Example 1 To address the problems of existing technologies causing significant secondary disturbance to the roadbed and the tendency for re-tilting during secondary installation, thus making it difficult to guarantee correction accuracy, such as... Figures 1-8 As shown, a roadbed monitoring observation pile is provided, including a settlement plate, an initial rod 2 set on the settlement plate 1, a support plate 3 set on the settlement plate 1 to support the initial rod 2, an observation rod 4 movably set on the initial rod 2, the initial rod 2 including an initial measuring rod 5 and an initial sleeve 6 set on the settlement plate 1, the observation rod 4 including a measuring rod 7 and a sleeve 8, and an adjustment structure 9 for verticality adjustment movably set on the initial rod 2. The observation rod 4 is installed on the initial rod 2 through the adjustment structure 9. The adjustment structure 9 includes a fixing structure 10 threaded on the initial rod 2, an adjustment plate 11 with a connector rotatably set on the fixing structure 10, and an adjustment component 12 set on the fixing structure 10 to adjust the verticality of the adjustment plate 11. The observation rod 4 cooperates with the connector on the adjustment plate 11.

[0023] In practice, after the roadbed is filled to the design height, settlement monitoring piles need to be installed. This involves digging a pit at a designated location on the roadbed, installing a settlement plate 1 with an initial rod 2 in the pit, and backfilling the pit. When the settlement plate 1 and the initial rod 2 tilt, the connector can be adjusted to be perpendicular to the horizontal plane using the adjusting structure 9. A leveling rod is then installed on the connector for settlement monitoring (the total station monitors settlement by observing the leveling rod and elevation position). When the roadbed filling needs to be increased, the leveling rod needs to be removed, and an observation rod 4 is installed on the connector. Then, the roadbed filling is carried out, and a leveling rod is installed on the measuring rod 7 for settlement monitoring. This process is repeated, and if necessary, another observation rod 4 is installed on the current observation rod 4 for settlement monitoring. In this embodiment, when the settlement plate tilts, an adjustment structure is installed on the initial rod, and the fixing structure in the adjustment structure is fixed to the initial rod. Then, the verticality of the connector on the adjustment plate is adjusted by the adjustment component (so that the connector is perpendicular to the horizontal plane). Then, an observation rod is installed on the connector. This effectively avoids secondary disturbance to the roadbed. The correction through the adjustment structure makes the correction accuracy high, improves construction efficiency, and reduces construction costs.

[0024] Example 2 Based on Embodiment 1, the fixing structure 10 includes a fixed sleeve 13 with internal threads that mates with the initial sleeve 6, a support rod 14 disposed on the fixed sleeve 13, and an annular sleeve 15 disposed on the support rod 14. The fixing structure is fixed to the initial sleeve by the fixed sleeve, and the support rod is disposed on the fixed sleeve. The annular sleeve is disposed on the support frame. The structure is simple and facilitates the adjustment plate to be installed on the annular sleeve for rotation to adjust the perpendicularity of the connector. The fixed sleeve 13 includes a threaded fixed sleeve 16 that mates with the initial sleeve 6, a protective sleeve 17 disposed on the threaded fixed sleeve 16 and sleeved on the initial measuring rod 5 to support the initial measuring rod 5, and a mounting plate 18 disposed on the protective sleeve 17 to mount the support rod 14.

[0025] The adjusting plate 11 includes a plate body 19, a connecting rod 20 disposed on the bottom of the plate body 19, a rotating ball 21 disposed on the connecting rod 20 and rotatably engaged with the annular sleeve 15, and a connector disposed on the top surface of the plate body 19. The connector includes an inner connector 22 disposed on the plate body 19 with internal or external threads, an outer connector 23 disposed on the plate body 19 and fitted onto the inner connector 22 with external threads, and a threaded sleeve 24 with internal threads that engages with the outer connector 23. The measuring rod 7 of the observation rod 4 engages with the inner connector 22, and the sleeve 8 engages with the threaded sleeve 24. The adjusting plate rotates within the annular sleeve by connecting the rotating ball under the plate body, so as to adjust the plate body to be parallel to the horizontal plane, that is, to adjust the connector to be perpendicular to the horizontal plane. The structure is simple and easy to adjust.

[0026] The adjusting component 12 includes multiple L-shaped support rods 25 arranged on the fixed sleeve 13 along the circumference of the fixed sleeve 13. Each L-shaped support rod 25 includes a horizontal rod 26 connected to the fixed sleeve 13 and a vertical threaded rod 27 connected to the horizontal rod 26. An adjusting rod 28 is threaded on the vertical threaded rod 27 so that the adjusting plate 19 is parallel to the horizontal plane. By threading the adjusting rod on the vertical threaded rod of the L-shaped support rod, the adjusting component can restrict the rotation of the plate by adjusting the height of the adjusting rod. Thus, the plate is kept parallel to the horizontal plane by the limiting effect of multiple adjusting rods at different positions.

[0027] In practice, when the settlement plate 1 tilts, the initial rod 2 also tilts. At this time, the fixing sleeve 13 is fixed to the threaded fixing sleeve 16, which is threaded onto the initial sleeve 6. The protective sleeve 17 limits the rotation distance of the threaded fixing sleeve 16 on the initial sleeve 6. After the fixing sleeve 6 rotates to the correct position, the adjusting rod 28 is first adjusted to move downward along the vertical threaded rod 17. With the assistance of the auxiliary measuring equipment, the adjusting plate 19 drives the rotating ball 21 to rotate in coordination with the annular sleeve 15 to adjust the plate 19 to a horizontal state. Then, each adjusting rod 28 is adjusted to move upward along the vertical threaded rod 17 to contact the bottom surface of the plate 19 to limit the plate 19 to a horizontal position. At this time, the connector is perpendicular to the horizontal plane. A leveling rod is then installed on the inner connector for roadbed settlement monitoring, or a measuring rod 7 is installed on the inner connector. A threaded sleeve 24 is installed on the outer connector 23, and a sleeve 8 is installed on the threaded sleeve 24.

[0028] Example 3 Based on Embodiment 2, the adjusting rod 28 is provided with a shim 29 that contacts and engages with the plate 19. Providing a shim on the adjusting rod increases the friction between the adjusting rod and the plate, preventing the plate from easily rotating horizontally.

[0029] Example 4 Based on Embodiment 3, a nut 30 is also provided on the vertical threaded rod 27 to limit the adjustment rod 28. The purpose of providing the nut on the vertical threaded rod to further limit the adjustment rod is to further ensure the stability of the plate after it is parallel to the horizontal plane.

[0030] In practice, considering that the plate 19 can also rotate horizontally, the installation and stability of the leveling rod or observation rod 4 may be affected. Fixing the plate 19 could be considered, such as by providing protruding holes at the bottom of the plate 19 to cooperate with the adjusting rod, or other structures. Of course, the appropriate method should be chosen based on specific needs in practice. Since the shims can provide some anti-rotation protection, the plate can be manually fixed during installation to install the leveling rod or observation rod 4. Depending on the actual situation, the adjusting structure can also be set between pairs of observation rods.
