Description

Technical Field

[0001] This utility model relates to the field of engineering surveying technology, and more specifically, to a surveying control stake suitable for plateau permafrost regions. Background Technology

[0002] Survey control stakes are control markers that need to be retained for a relatively long period of time. They are mainly used in horizontal control surveying, vertical control surveying, and construction phases. They are reference points that are repeatedly used in each design phase and during construction to ensure survey accuracy and construction quality.

[0003] Accurate surveying is crucial for various engineering projects (such as road construction, building construction, and pipeline laying) in high-altitude permafrost regions. Traditional control stakes can meet basic requirements in ordinary environments, but high-altitude permafrost regions present unique and harsh conditions: extremely low temperatures keep the soil frozen year-round, with frequent freeze-thaw cycles, making ordinary control stakes prone to displacement, tilting, or even damage due to soil expansion and contraction; in strong winds, conventional control stakes have poor stability; and the intense sunlight in high-altitude areas causes some materials to age and deform, affecting the accuracy and reliability of measurements. These problems severely restrict the precision and continuity of engineering surveying. Therefore, a specialized control stake is needed for application in high-altitude permafrost environments.

Example

[0025] This embodiment provides a measurement control stake suitable for plateau permafrost regions, which includes a cylindrical stake body 10 and a measurement marker component 40.

[0026] Furthermore, an inner cavity 30 is formed inside the pile body 10. The inner cavity 30 is arranged along the axial direction of the pile body 10 and extends through the top of the pile body 10 to form an opening 310. The inner cavity 30 is filled with thermal insulation material. The hollow structure reduces the overall weight of the pile body 10, making it easier to transport in high-altitude areas. The filled thermal insulation material can effectively reduce the impact of permafrost temperature changes on the pile body 10 and improve the service life of the pile body 10.

[0027] The measuring marker component 40 is disposed on the top of the pile body 10. The measuring marker component 40 is mainly used for the alignment of measuring instruments and can be designed with reference to existing technology. It is detachably connected to the pile body 10 and covers the opening 310. The detachable design facilitates separate maintenance and replacement of the pile body 10 and the measuring marker component 40, reducing maintenance costs.

[0028] Furthermore, the bottom of the measuring marker component 40 is provided with a plug-in block 410 into which the opening 310 can be inserted. The measuring marker component 40 can be inserted into the inner cavity 30 for quick fixation. Optionally, the outer surface of the plug-in block 410 is provided with external threads, and the top of the inner cavity 30 is provided with internal threads for matching the external threads. The threaded connection between the measuring marker component 40 and the pile body 10 increases the reliability of the connection.

[0029] The pile body 10 is made of high-strength, low-temperature resistant, and aging-resistant carbon fiber reinforced polymer composite material, which improves the performance and service life of the pile body 10. The bottom of the pile body 10 is provided with a conical tip 20 to reduce resistance when the pile body 10 is inserted into the soil. A detachable protective shell 210 is provided outside the tip 20. The protective shell 210 is made of hard alloy material, which can improve the overall strength of the tip 20. The detachable design allows the protective shell 210 to be replaced promptly after wear, increasing the convenience of maintenance. Optionally, the protective shell 210 is connected to the pile body 10 by screws. Multiple screw holes can be provided on the surface of the protective shell 210, and screws can be used to fix the protective shell 210 to the tip 20 through the screw holes.

[0030] Furthermore, the outer surface of the pile body 10 is provided with a threaded groove 110, which extends from the top end to the bottom end of the pile body 10. The threaded groove 110 can increase the friction between the pile body 10 and the soil, preventing the pile body 10 from loosening.

[0031] A square-shaped windproof cover 50 is fitted over the outer side of the measuring marker component 40. The measuring marker component 40 is cylindrical, and in strong winds, turbulence can form around the column, causing high-frequency vibrations in the pile body 10 and potentially leading to loosening. The windproof cover 50 disrupts this turbulence, effectively reducing the impact of strong winds on the pile body 10 and extending its service life. The outer surface of the windproof cover 50 has a corrugated air-guiding structure 510 extending along its height. This corrugated structure further disperses wind force, maintaining the stability of the pile body 10. The windproof cover 50 is made of lightweight, high-strength aluminum alloy with an anti-corrosion treatment, providing excellent weather resistance.

[0032] In summary, this utility model embodiment provides a measurement control stake suitable for high-altitude permafrost regions. It includes a cylindrical stake body 10 and a measurement marker component 40. The stake body 10 has an internal cavity 30, which is arranged along the axis of the stake body 10 and extends through the top of the stake body 10 to form an opening 310. The internal cavity 30 is filled with insulation material. The hollow structure reduces the overall weight of the stake body 10, facilitating transportation in high-altitude areas. The insulation material effectively reduces the impact of permafrost temperature changes on the stake body 10, extending its service life. The measurement marker component 40 is located at the top of the stake body 10, detachably connected to the stake body 10, and covers the opening 310. The detachable design facilitates separate maintenance and replacement of the stake body 10 and the measurement marker component 40, reducing maintenance costs. This measurement control stake has a novel structure, is convenient to use, and has significant practical value.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
