Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of geotechnical engineering investigation and sampling, and specifically relates to a manual soil sampler for geotechnical engineering investigation. Background Art
[0002] Samplers used in geotechnical engineering investigation are divided into manual and electric types. Manual geotechnical engineering investigation samplers are generally used more frequently in the process of sampling soft soil due to their simple structure and convenient carrying and use. During the operation of existing manual samplers, the sampling tube is screwed into the soil by driving the handle. In the process of manual screw-in sampling, due to the relatively long length of the sampling tube itself, and in order to facilitate the rapid screwing-in of the sampling tube, the end of the sampling tube is relatively sharp, and the contact surface with the ground during the screwing-in process is limited, resulting in the sampling tube being prone to swing during the screwing-in process, and even tilting and screwing into the soil, affecting the accuracy of exploration sampling. Summary of the Utility Model
[0003] To solve the above technical problems, the utility model provides a manual soil sampler for geotechnical engineering investigation. The sampler can avoid the sampling tube swinging during the screwing-in process and tilting and screwing into the soil, and improve the sampling accuracy.

A driving handle for driving the sampling tube is installed at the tail end of the sampling tube. The sampler further includes a stabilizing mechanism arranged at the front end of the sampling tube for auxiliary support during the process of screwing in the sampling tube. Threads are provided on the outer wall of the sampling tube. The stabilizing mechanism includes a support ring, a mounting ring threadedly sleeved outside the sampling tube, and an elastic support assembly connecting the support ring and the mounting ring. The support ring is located in the area outside the end of the sampling tube, and the mounting ring is threadedly sleeved at a position adjacent to the sampling end of the sampling tube. A sampling hole matching the sampling tube is opened on the support ring. Multiple groups of elastic support assemblies are provided and are dispersedly arranged around the sampling tube.
[0005] A preferred technical solution of the utility model: The outer diameter of the support ring is larger than the outer diameter of the mounting ring. The sampling hole is opened in the middle of the support ring. Pedals are symmetrically arranged on both sides of the support ring. The two groups of pedals are respectively slidably connected to the support ring through sliding components, and a limiting component for limiting the sliding adjustment of the pedals is arranged on the support ring.
[0006] The preferred technical solution of the present utility model: Multiple sets of elastic components are distributed in an annular array around the sampling hole.

[0007] The preferred technical solution of the present utility model: The sliding component includes a chute opened at the lower end of the support ring. T-shaped grooves are opened on the opposite inner walls of the chute. Two T-shaped blocks are slidably connected to the two T-shaped grooves, and the two T-shaped blocks are respectively fixed to both sides of the pedal.
[0008] The preferred technical solution of the present utility model: The limiting component includes a threaded hole opened on the support ring.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. The following embodiments are used to illustrate the present utility model.
[0016] The embodiment provides a manual soil sampler for geotechnical investigation, as Figures 1 to 3 shown, which includes a sampling pipe 1. A driving handle 101 for driving the sampling pipe 1 is installed at the tail end of the sampling pipe 1. The sampling part of the sampling pipe 1 is the same as that of the existing sampling pipe. Threads are provided on the outside of the sampling pipe 1. Similar to a threaded rod, a stabilizing mechanism for auxiliary support during the screwing-in process of the sampling pipe 1 is further included at the front end of the sampling pipe 1 for sampling. The stabilizing mechanism includes a support ring 2, a mounting ring 3 threadedly sleeved on the outside of the sampling pipe 1, and an elastic support assembly 4 connecting the support ring 2 and the mounting ring 3. The support ring 2 is located in an area outside the end of the sampling pipe 1. The mounting ring 3 is threadedly sleeved at a position adjacent to the sampling end of the sampling pipe 1. A sampling hole matching the sampling pipe 1 is provided on the support ring 2. The outer diameter of the support ring 2 is larger than that of the mounting ring 3. The sampling hole is opened in the middle of the support ring 2. Multiple groups of the elastic support assemblies 4 are provided and are dispersedly arranged around the sampling pipe 1. During the use of the utility model, through the mutual cooperation of the mounting ring 3 and multiple groups of elastic support assemblies, auxiliary support is provided for the screwing-in of the sampling pipe 1, the support area is increased, and the sampling pipe 1 is prevented from swinging during the screwing-in process and thus being screwed in obliquely on the soil, further facilitating more accurate subsequent exploration and detection. Multiple groups of elastic support assemblies are distributed in an annular array state around the sampling hole, and through multiple groups of elastic support assemblies, the support effect is ensured.
[0017] In the embodiment, as Figure 2 and Figure 3 shown, the elastic support assembly 4 includes a sleeve 401 fixed to the upper end of the support ring 2. A sliding rod 402 is slidably connected to the sleeve 401. One end of the sliding rod 402 is fixed to the mounting ring 3. A spring 403 is sleeved on the outside of the sleeve 401. The two ends of the spring 403 are respectively connected to the support ring 2 and the mounting ring 3. During the process of manually sampling with the sampling pipe 1, the sampling pipe 1 is pushed upward towards the sampling soil. During the pushing process, the support ring 2 is made to abut against the upper surface of the soil. And as the sampling pipe 1 is continuously pushed, each sliding rod 402 slides on each sleeve 401 respectively and the spring 403 is deformed by force to generate elastic force. Through the elastic force of the spring 403, the support ring 2 is pushed to keep abutting against the upper side of the soil.
[0018] In the embodiment, as Figure 1 and Figure 2As shown, pedal boards 5 are symmetrically arranged on both sides of the support ring 2. The two groups of pedal boards 5 are respectively slidably connected to the support ring 1 through sliding components, and a limiting component for limiting the sliding adjustment of the pedal boards 5 is arranged on the support ring 2. During the process of screwing the sampling tube 1 for sampling, the two groups of pedal boards 5 slide outwards from the support ring 2 and are limited and fixed. When the operator operates the sampling tube 1, both feet step on the two groups of pedal boards 5, and through the stepping action, the deviation and shaking of the support ring 2 are prevented.
[0019] In the embodiment, as Figure 2 and Figure 3 shown, the sliding component includes a chute 601 opened at the lower end of the support ring 2. T-shaped grooves 602 are opened on the opposite inner walls of the chute 601. Two T-shaped blocks 603 are slidably connected to the two groups of T-shaped grooves 602. The two groups of T-shaped blocks 603 are respectively fixed to both sides of the pedal board 5. Through the interaction between the T-shaped groove 602 and the T-shaped block 603 on the chute 601, it is convenient to assist the sliding of the pedal board 5. The limiting component includes a threaded hole 701 opened on the support ring 2. The threaded hole 701 communicates with the inside of the chute 601. A bolt 702 for abutting against the upper end of the pedal board 5 is threadedly engaged on the threaded hole 701. After the pedal board 5 slides out, the bolt 702 is rotated. During the rotation process, through the meshing transmission between the bolt 702 and the threaded hole 701, one end of the bolt 702 abuts against the upper end of the pedal board 5 to limit the slid-out pedal board 5.
[0020] Before manually sampling using the sampling tube 1, the mounting ring 3 is mounted on the sampling tube 1 by means of threads. During the mounting process, due to the connection of the elastic support assembly, the support ring 2 is located on the front side of the sampling tube 1. During the process of manually sampling using the sampling tube 1, the sampling tube 1 is pushed upward towards the sampling soil. During the pushing process, the support ring 2 abuts against the upper surface of the soil. And as the sampling tube 1 is continuously pushed, each slide rod 402 slides on each sleeve 401 respectively, causing the spring 403 to be deformed by force to generate elastic force. Through the elastic force of the spring 403, the support ring 2 is pushed to keep abutting against the upper side of the soil. And during the continuous pushing of the sampling tube 1, the front end of the sampling tube 1 abuts against the surface of the soil. At this time, the sampling tube 1 is driven to rotate by the driving handle 102, assisting the sampling tube 1 to be screwed into the soil for sampling operation. And during the process of screwing in for sampling, through the elastic force of each spring 403, the support ring 2 is pushed to keep abutting against the soil. Through the abutting and supporting effect of the support ring 2, the screwing-in of the sampling tube 1 is assisted and supported, increasing the support area, avoiding the sampling tube 1 from swinging during the screwing-in process and causing it to be screwed in obliquely on the soil, and further facilitating more accurate exploration and detection in the follow-up; and during the process of screwing in the sampling tube 1 for sampling, the two pedal plates 5 slide outwards from the support ring 2 and are limited and fixed. When the operator operates the sampling tube 1, both feet step on the two pedal plates 5. Through the stepping action, the deviation and shaking of the support ring 2 are prevented, and further the anti-swing support effect of the sampling tube 1 during the sampling process is improved.
[0021] As described above, this is only one embodiment of the present utility model, and its description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the appended claims.
