[0002] Railway section tunnels are underground passage structures in railway systems used to cross mountains, rivers, or other obstacles. They play an important role in modern railway transportation, not only shortening route length but also improving the overall operational efficiency and safety of the line. Soil sampling in railway section tunnels is a highly specialized task, typically used for assessing geological conditions, environmental impact assessments, and groundwater pollution investigations. This work requires following certain procedures and precautions to ensure the accuracy and safety of the sampling.

[0003] Existing soil sampling devices are not convenient for isolating and sealing soil during use, which can lead to sample contamination after sampling, affecting the accuracy and reliability of subsequent analysis results. When sampling soil from multiple locations or depths, if the equipment cannot effectively isolate each sample, cross-contamination between samples may occur, affecting the accuracy of the data.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] This utility model provides a soil sampling device for railway tunnel sections, such as... Figures 1-5 As shown, the soil sampling device for railway tunnels includes a sampling tube 1, a sealing mechanism is snapped into the bottom of the sampling tube 1, and a sampling mechanism is fixedly connected to the top of the inner wall of the sampling tube 1. The sealing mechanism includes a retaining ring 2. The outer surface of the retaining ring 2 is snapped onto the outer surface of the bottom of the sampling tube 1 by a sealing ring. A sealing sleeve 3 is fixedly connected to the upper surface of the retaining ring 2. A hook and loop fastener 4 is fixedly connected to the upper surface of the sealing sleeve 3. A hook and loop fastener 5 is attached to the upper surface of the hook and loop fastener 4. When sampling soil, the sealing mechanism is placed inside the sampling tube 1. The sealing mechanism can effectively prevent soil from being contaminated. For soil samples that need to maintain specific humidity conditions, the seal can effectively prevent water loss or the infiltration of external water, and maintain the original physical and chemical properties of the sample.

[0017] The sampling mechanism includes an internal gear 6, the outer surface of which is fixedly connected to the top of the inner wall of the sampling tube 1. A gear 7 meshes with the inner wall of the internal gear 6, and a connecting frame 8 is fixedly connected to the upper surface of the gear 7. The sampling mechanism enables rapid sampling, shortening the sampling time. Rapid sampling means that more sampling tasks can be completed in a shorter time. Rapid sampling can minimize the potential impact of external factors on the sample, help maintain the original state of the sample better, and thus improve the accuracy of the analysis results.

[0018] A handheld rod 9 is fixedly connected to the upper surface of the connecting frame 8, and a connecting rod 10 is fixedly connected to the bottom of the handheld rod 9. A scraper 11 is fixedly connected to one end of the connecting rod 10. When a person holds the outer casing 12 with one hand and the handheld rod 9 with the other hand, the handheld rod 9 is rotated. When the handheld rod 9 rotates, it drives the connecting frame 8 and the gear 7 to rotate on the inner gear 6. When the handheld rod 9 rotates, it drives the connecting rod 10 to rotate. The connecting rod 10 drives the scraper 11 at the bottom to rotate. The scraper 11 extends into the soil and rotates and divides the soil.

[0019] The outer surface of the retaining ring 2 is snapped with the outer shell 12. The outer surface of the outer shell 12 is provided with a sliding groove. The sliding block 13 is slidably connected inside the sliding groove. The sliding block 13 slides on the outer shell 12, which facilitates the up and down movement of the cutting disc 16.

[0020] A rotating block 14 is fixedly connected to one side of the slider 13. A rotating block 15 is rotatably connected to the middle of the rotating block 14 via a rotating rod. A cutting blade 16 is fixedly connected to one end of the rotating block 15. A rotating rod 17 is fixedly connected to the outer surface of the cutting blade 16. When the rotating rod 17 is rotated, it drives the cutting blade 16 to rotate. The cutting blade 16 rotates at the bottom of the sampling tube 1 via the rotating block 14 and the rotating block 15, which facilitates the separation of the soil separated by the scraper 11, so that the sealed sleeve 3 contains complete soil, thereby obtaining the required soil sample.

[0021] A piston 18 is fixedly connected to the upper surface of the hook and loop fastener 5. The outer surface of the piston 18 is inserted into the inside of the sampling tube 1. A tension rod 19 is fixedly connected to the upper surface of the piston 18. When a person pulls the tension rod 19, the tension rod 19 drives the piston 18 upward, and the piston 18 drives the sealing sleeve 3 upward. The piston 18 plays a vacuum lifting effect inside the sampling tube 1, which makes it easy to lift the soil upward for sampling.

[0022] Specifically, when soil sampling is required, the retaining ring 2 and sealing sleeve 3 are fitted onto the outside of the sampling tube 1. The sealing sleeve 3 and piston 18 are connected and fixed using Velcro A 4 and Velcro B 5. The bottom of the sampling tube 1 is brought into contact with the ground. The operator holds the outer casing 12 in one hand and the handheld rod 9 in the other, rotating the handheld rod 9. When the handheld rod 9 rotates, it drives the connecting frame 8 and gear 7 to rotate on the internal gear 6. The rotation of the handheld rod 9 drives the connecting rod 10 to rotate, which in turn drives the scraper 11 at the bottom to rotate. The scraper 11 extends into the soil, rotating and dividing the soil. After division, the operator pulls the tension rod 19, which drives the piston 18 upward. The piston 18 then... With the dynamic sealing sleeve 3 facing upwards, the soil is isolated and sealed by the sealing sleeve 3. Then, the rotating rod 17 is rotated, which drives the cutting blade 16 to rotate. The cutting blade 16 rotates at the bottom of the sampling tube 1 through rotating block A 14 and rotating block B 15, which facilitates the separation of the soil separated by the scraper 11, so that the soil inside the sealing sleeve 3 is intact, thereby obtaining the required soil sample. When it is necessary to collect soil from the next area, the sealing sleeve 3 is removed and replaced with a new sealing sleeve 3. This can maintain a clean environment during each sampling. The seal can effectively prevent moisture loss or the infiltration of external moisture, maintain the original physical and chemical properties of the sample, and thus improve the accuracy of the analysis results.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
