Technical Field

[0001] The utility model relates to the technical field of detection equipment for foundation construction, in particular to a device for detecting the thickness of sediment in foundation engineering. Background Art

[0002] During the construction of foundation engineering, the thickness of the sediment at the bottom of the bored pile is tested. Since the thickness of the sediment will directly affect the bearing capacity and quality of the pile foundation and the safety of the buildings on the piles, it is very important to test the thickness of the sediment at the bottom of the pile. During the test, the staff uses a measuring rope to measure. The staff usually lowers the measuring rope along the edge of the pile. Since the sediment has a certain viscosity, the surveyors cannot place the measuring rope to the bottom well, and the measurement data is easily affected by human factors.

[0020] The moving mechanism 4 includes a moving plate 401, a fixed frame 402, a hub motor 403, a tire 404 and an ultra-thin stepping motor 405. The number of the moving plates 401 is two. The two moving plates 401 are respectively located in two moving grooves and are slidably connected, and the moving plates 401 are provided with gear grooves arranged equidistantly. The hub motor 405 is located on the main frame 1 and is fixedly connected, and the hub motor 405 is connected to the motor gear through a motor shaft. The motor gear is located between the two moving plates 401 and is meshed with the gear groove on the moving plate 401. One end of the moving plate 401 is fixedly connected to the fixed frame 402, and the hub motor 403 is rotatably connected in the fixed frame 402, and a tire 404 is installed on the rotating end of the hub motor 403.

[0021] The movable plate 401 is provided with a sliding groove, and a limiting plate is slidably connected in the sliding groove. The limiting plate is located in the main frame 1 and fixedly connected.

[0022] The measuring mechanism 3 includes a positioning frame 301, a connecting frame 302, a rack 303, a gear 304 and a dual-axis servo motor 305. The number of the positioning frames 301 is two groups, and the number of each group of positioning frames 301 is two. The two groups of positioning frames 301 are respectively located on the two side walls of the main frame 1 and are fixedly connected, and a rack 303 is slidably connected in the positioning frame 301. The bottom end of the rack 303 is fixedly connected to the connecting frame 302. The number of the dual-axis servo motors 305 is two. The two dual-axis servo motors 305 are respectively located on the two side walls of the main frame 1 and are fixedly connected, and the two motor shafts of the dual-axis servo motor 305 are respectively fixedly connected with gears 304.

After the contact is completed, the measuring mechanism 3 is driven upward by the moving mechanism 4, and the worker observes the scale on the rack 303 to determine the depth of the sediment.
