[0002] During the construction of projects such as tunnels and highways, sampling the geotechnical of the construction site is an essential link, because the samples taken have high reference value for judging whether the geological structure of this area is suitable for tunnel excavation and highway construction.
[0003] The existing technology has the following problems:
[0004] The sampling rod is the connection part between the driving device and the sampling drill bit. Generally, it has a segmented structure and is connected to each other through a threaded structure, so as to adjust the overall length of the sampling rod and sample the geotechnical at different depths. However, the thickness of the connection part of the sampling rod is relatively small compared to the overall part, resulting in relatively weak overall strength of the connection part, and thus the connection part is extremely prone to damage.
[0005] Therefore, we propose a new type of geotechnical exploration sampling device to solve the above disadvantages. Content of the Utility Model
[0006] The purpose of the utility model is to solve the problem that the thickness of the connection part of the sampling rod in the existing technology is relatively small compared to the overall part, resulting in relatively weak overall strength of the connection part, and thus the connection part is extremely prone to damage, and to propose a new type of geotechnical exploration sampling device.

The sampling rod is composed of a rod body, a threaded joint, a threaded groove and a reinforcing sleeve. One end of the rod body is provided with a threaded joint, and the other end of the rod body is provided with a threaded sleeve. Adjacent rod bodies are connected through the threaded joint and the threaded sleeve. A reinforcing sleeve is arranged on the surface of the rod body at the position of the threaded sleeve, and internal threads are opened on the inner side surface of the reinforcing sleeve. External threads are arranged on the surface of the rod body.

The sampling rod 6 is composed of a rod body 9, a threaded joint 10, a thread groove 11 and a reinforcing sleeve 12. One end of the rod body 9 is provided with a threaded joint 10, the other end of the rod body 9 is provided with a threaded sleeve, adjacent rod bodies 9 are connected through the threaded joint 10 and the threaded sleeve, a reinforcing sleeve 12 is arranged on the surface of the rod body 9 at the position of the threaded sleeve, and an internal thread is opened on the inner side surface of the reinforcing sleeve 12, and an external thread is arranged on the surface of the rod body 9.
[0025] In this implementation manner: during installation and use, first select an appropriate amount of rod bodies 9 according to the sampling depth, and then sequentially thread-connect adjacent rod bodies 9 through the threaded joint 10 and the thread groove 11. At the same time, the reinforcing sleeve 12 is thread-connected to the external thread of the rod body 9, so that the reinforcing sleeve 12 wraps around the connection part of the rod body 9, improving the overall strength of the sampling rod 6 and preventing it from being damaged. After that, the sampling rod 6 can be connected to the fixed platform 1 and the drill bit body 8.
[0026] Specifically, the drill bit body 8 is composed of a fixed drill bit 14, a cover body 15, a limiting concave body 16, a fixed hook 17, a pressing strip 18 and a damping spring 19.
