Therefore, a foundation detection sampling device for water conservancy projects is needed. Utility Model Content

[0004] The purpose of the utility model is to provide a foundation detection sampling device for water conservancy projects to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] It also includes a linkage-type supporting and retaining structure and a depth-adjustable limiting structure. The linkage-type supporting and retaining structure is installed at one end of the two sliding seats that are separated from each other and is connected to the mobile base.

[0015] (1) The device is pushed to the designated sampling position through the lifting transmission structure and the linkage support and retention structure. Secondly, the lifting transmission structure can be used to drive the screw to move the sampling tube downward. During the downward movement, the lifting plate drives the two sliding seats to move downward. At this time, the two connecting plates move downward at the same time, and cooperate with the action of multiple components, so that the two sliders in each slide groove can move relative to each other. In addition, the setting of the push-pull rod is cooperated, so that the two support plates drive the guide rod to move downward, and then the multiple soil nails provided at the bottom of the two support plates can be driven into the soil of the foundation at the same time, effectively ensuring the stability of the sampling device during sampling, so that there is no need to manually stabilize the sampling device before sampling, which greatly improves the sampling efficiency.

[0016] (2) By setting up a depth-adjustable limit structure, the adjusting rod can be no longer tightly fixed by loosening the hand screw, so that the adjusting plate can be manually raised and lowered in the sampling tube, thereby making the sampling depth in the sampling tube adjustable to meet the needs of sampling soil at different depths.
