Description

Technical Field

[0001] The invention belongs to the field of exploration technology, in particular to a soil layer sampling device for construction engineering. Background Art

[0002] Soil sampling devices are crucial in construction projects. They are mainly used to obtain underground soil samples to evaluate soil properties and bearing capacity. These devices can help engineers and geologists gain a deeper understanding of foundation conditions, thereby formulating effective design and construction plans. Common sampling methods include drilling sampling, static penetration and dynamic sampling, which are suitable for different soil layers and environmental conditions. With the development of technology, new sampling devices continue to emerge, which improves the accuracy and efficiency of sampling and promotes engineering safety and sustainable development.

[0003] After searching, the existing patent (Announcement No.: CN118087485B) discloses a soil layer surveying device for engineering construction, including a frame, a winch is fixedly installed on one side of the frame, a sampling mechanism is arranged on the frame, a power mechanism for controlling the sampling mechanism to take samples is slidably connected to the frame, the output end of the winch is connected to the power mechanism, a hydraulic cylinder is arranged on the frame, the power mechanism is arranged at the output end of the hydraulic cylinder, a connecting pipe is arranged on the power mechanism, and a water supply component is arranged at one end of the connecting pipe away from the power mechanism. The advantage is that: the soil layer surveying device for engineering construction, by arranging the sampling mechanism, avoids relative rotation between the sampling tube and the rock and soil sample core when sampling the rock and soil, thereby reducing the disturbance of the rock and soil sample core during the sampling process, and after the sampling is completed, the sampling tube is taken out from the outer tube, and then the first half tube and the second half tube are opened, so that a complete and continuous rock and soil sample can be obtained, thereby ensuring the integrity and continuity of the sampled sample.

[0004] However, in the actual use of the above scheme, only one soil layer can be sampled at a time, which increases time and cost, especially under complex geological conditions that require multiple sampling; finally, important soil layer characteristics may be missed, affecting the accuracy and safety of engineering design. Such limitations are particularly evident in large or complex projects.

When the limit plate contacts the second gear ring, the fourth motor uses the first driving gear and the first gear ring to drive the second gear ring to rotate, thereby starting to drive the limit plate to rotate through the second gear ring. The teeth on the second gear ring and the limit plate have a certain height, so that during the downward movement of the sampling barrel, the limit plate and the sampling barrel can be driven by the second gear ring to rotate a certain angle, thereby squeezing the support plate through the soil, forcing the support plate to rotate and engage with the engaging hemisphere, thereby supporting the collected soil and preventing the soil from falling out of the sampling barrel.
