[0024] Specifically, the first rotating column 4 is rotated to drive the threaded column 5 to rotate. When the threaded column 5 rotates, the slider 6 and the T-shaped column 8 are driven to slide. As the slider 6 slides outward, the outer wall of the baffle plate 9 on one side is attached to the outer wall of the first pipe barrel 10, and the outer wall of the baffle plate 9 on the other side is attached to the inner wall of the foundation pit, so that the first pipe barrel 10 and the second pipe barrel 13 are spliced ​​more tightly, thereby achieving the effect of improving the strength of the caisson.

[0025] Reference Figure 1 and Figure 3The limiting assembly includes a first limiting groove 11, the first tube barrel 10 is provided with the first limiting groove 11, the outer wall of the first tube barrel 10 is attached to the second tube barrel 13, the outer wall of the second tube barrel 13 is fixedly connected to the first limiting block 12, the outer wall of the first limiting block 12 is slidably connected to the inner wall of the first limiting groove 11; the outer wall of the first limiting block 12 is slidably connected to the third tube barrel 14, and the outer wall of the third tube barrel 14 is provided with a second limiting groove 15;

[0026] Specifically, the first pipe barrel 10 is placed on the upper surface of the first pad 1 and the second pad 22, and then the second pipe barrel 13 is slowly moved downward from the top, so that the first limiting block 12 slides into the inner wall of the first limiting groove 11, thereby connecting the first pipe barrel 10 and the second pipe barrel 13, and repeating this step, so that the bottom is completed by splicing two pairs of first pipe barrels 10 and second pipe barrels 13, making the foundation more solid.

[0027] Reference Figure 1 and Figure 4 The outer wall of the third tube barrel 14 is slidably connected to the inner wall of the second limiting groove 15, and the outer wall of the third tube barrel 14 is fixedly connected to the second limiting block 16, and the outer wall of the second limiting block 16 is slidably connected to the inner wall of the first limiting groove 11; the upper surface of the first skid 1 is fixedly connected to the support rod 18, the outer wall of the support rod 18 is rotatably connected to the second rotating column 19, and the outer wall of the second rotating column 19 is fixedly connected to the connecting column 20; one end of the connecting column 20 is fixedly connected to the connecting rod 21, and the outer wall of the first skid 1 is fixedly connected to the sliding block 17; the outer wall of the sliding block 17 is slidably connected to the second skid 22, and the outer wall of the second skid 22 is attached to the outer wall of the first skid 1; the interior of the second skid 22 is provided with a third limiting groove 23, and the outer wall of the sliding block 17 is slidably connected to the inner wall of the third limiting groove 23;

[0028] Specifically, when the caisson needs to be lowered, the connecting rod 21 is pulled outward at the same time, and the connecting rod 21 drives the connecting column 20 and the second rotating column 19 to move, thereby driving the support rod 18 to move. The movement of the support rod 18 drives the first pad 1 and the second pad 22 to move, thereby achieving the effect of facilitating the installation of the first pad 1 and the second pad 22 and pulling them out after use.

[0029] Working principle: When the caisson is needed, the sliding block 17 on the outer wall of the first pad 1 is slid into the inner wall of the third limiting groove 23, so that the first pad 1 and the second pad 22 are quickly connected, the first pipe barrel 10 is placed on the upper surface of the first pad 1 and the second pad 22, and then the second pipe barrel 13 is slowly moved downward from the top, so that the first limiting block 12 slides into the inner wall of the first limiting groove 11, thereby connecting the first pipe barrel 10 and the second pipe barrel 13, repeating this step, so that the bottom is composed of two pairs of first The pipe barrel 10 and the second pipe barrel 13 are spliced ​​together. The bottom of the first pipe barrel 10 has no groove, which makes the foundation more solid. The fixed block 2 is placed on the top of the first block 1. The first rotating column 4 is rotated, and the first rotating column 4 rotates to drive the threaded column 5 to rotate. When the threaded column 5 rotates, it drives the slider 6 to move inside the shell 3. When the slider 6 moves, it drives the raised column under the T-shaped column 8 to slide on the inner wall of the sliding groove 7. As the slider 6 slides outward, the outer wall of the side baffle 9 is attached to the outer wall of the first pipe barrel 10. The outer wall of the baffle plate 9 on the other side is fitted to the inner wall of the foundation pit, so that the baffle plate 9 on the other side generates a thrust, and the first pipe barrel 10 and the second pipe barrel 13 are spliced ​​more tightly, so as to improve the strength of the caisson. After the bottom is installed, the third pipe barrel 14 is moved downward to make the outer wall of the second limiting groove 15 slide into the inner wall of the first limiting block 12, and the caisson is installed in sequence through the second limiting block 16. When the caisson needs to be excavated and lowered, the connecting rod 21 is pulled outward at the same time, and the connecting rod 21 drives the connecting column 20 to move, and the movement of the connecting column 20 drives the second rotating column 19 to move, and the movement of the second rotating column 19 drives the support rod 18 to move, thereby driving the first pad 1 and the second pad 22 to move, so that the sliding block 17 leaves the inside of the third limiting groove 23, so as to facilitate the installation of the first pad 1 and the second pad 22 and the effect of pulling it out after use. The caisson can not only achieve the effect of improving the strength of the caisson, but also achieve the effect of facilitating the installation of the first pad 1 and the second pad 22 and the effect of pulling it out after use.
