[0016] Please refer to Figures 1 to 4, a soil compaction experiment soil sampling device for foundation, which is composed of a movable mobile base 1, a support frame 2 arranged on the mobile base 1 for supporting the jacking assembly 3, a jacking assembly 3 arranged on the support frame 2 for driving the soil sampling assembly 4 to move up and down, and a soil sampling assembly 4 used in cooperation with the jacking assembly 3 for soil sampling. By setting the movable mobile base 1, the device can be moved to a suitable position during soil sampling. Then, the soil sampling assembly 4 is pushed deep into the ground by the up and down movement of the provided jacking assembly 3 for soil sampling operation. And the soil sampling assembly 4 is convenient for taking out the soil after soil sampling to improve work efficiency. The above-mentioned soil sampling assembly 4 convenient for taking out the soil is composed of a soil sampling cylinder 5 detachably connected to the jacking assembly 3 by means of pins, bolts, etc. and a soil pushing plate 6 arranged in the soil sampling cylinder 5 for pushing out the soil; and there is an opening on one side of the soil sampling cylinder 5, and then a sliding plate 7 detachably connected to the end of the soil sampling cylinder 5 by bolts is slidably arranged in the opening. And the soil pushing plate 6 is located between the soil sampling cylinder 5 and the sliding plate 7. One end of the soil pushing plate 6 extends to the outside of the soil sampling cylinder 5. During soil sampling, the soil pushing plate 6 is clamped at the bottom end of the inner wall of the soil sampling cylinder 5 by the sliding plate 7. The soil pushing plate 6 is adapted to the inner wall of the soil sampling cylinder 5. Chute grooves are opened on both vertical sides of the inner wall of the soil sampling cylinder 5. The soil pushing plate 6 is horizontally placed and provided with sliding blocks adapted to the chute grooves on both sides. The sliding blocks and the chute grooves are in sliding fit. When the soil sampling is completed, the sliding plate 7 is slid out by screwing out the bolts, and then the soil pushing plate 6 is moved to push out the taken soil for subsequent experiments.
[0017] The mobile base 1 for facilitating the movement of the device is composed of a mobile plate 8, wheels 9 arranged on the mobile plate 8, and a push handle 10 arranged on one side of the mobile plate 8; and there is an opening in the middle of the mobile plate 8 to facilitate the up and down movement of the soil sampling assembly 4. The support frame 2 is connected to the upper part of the mobile plate 8. During use, the mobile plate 8 is pushed by the push handle 10 to move, and then the jacking assembly 3 and the soil sampling assembly 4 are moved to the soil sampling position.
[0018] The jacking assembly 3 is composed of an electric push rod 11 arranged on the support frame 2 and a jacking plate 12 slidably matched with the support frame 2 vertically; and the output shaft of the electric push rod 11 passes through the end of the support frame 2 and is connected to the jacking plate 12. The bottom of the jacking plate 12 is detachably connected to the upper part of the soil sampling cylinder 5 by means of bolts, pins, etc. The way to realize the vertical sliding fit of the above-mentioned jacking plate 12 and the support frame 2 is to vertically open a guide rail on the support frame 2 and set a guide block on the side wall of the jacking plate 12. The guide block can slide in the guide rail. During soil sampling, the electric push rod 11 is started to drive the jacking plate 12 to move down, and then drive the connected soil sampling assembly 4 to move down. After the soil sampling is completed, the electric push rod 11 is reset to drive the soil sampling assembly 4 to move up to take out the soil.
