[0013] Compared with the prior art, the utility model has the beneficial effects that:

[0014] This invention achieves the assembly of the base plate through the combination mechanism. The two base plates are joined together, and then the fastening bolts pass through the fixing block and are threaded into the inner side of the fixing nut, thus completing the assembly of the two base plates. This facilitates subsequent demolding and improves work efficiency. The demolding mechanism enables the demolding of the outer and inner cylinders. First, the fixing pipe and the fixing guide rod are slidably connected. Then, the outer and inner cylinders are placed on the upper surface of the base plate, and concrete is poured into the inner side of the outer cylinder. After the concrete solidifies, the inner cylinder is lifted using a lifting device with lifting rings. During the upward sliding of the inner cylinder, when the limiting slider engages with the annular limiting groove… During alignment, the limiting slider, under the action of the compression spring, inserts into the inner side of the annular limiting groove. At this time, the inner cylinder continues to slide upward, and under the combined action of the limiting slider and the annular limiting groove, it drives the outer cylinder to slide upward, thereby realizing the demolding of the outer cylinder and the inner cylinder. Moreover, the setting of the fixed tube and the fixed guide rod can guide the outer cylinder, preventing the outer cylinder from shaking during demolding and preventing damage to the concrete pipe. This not only improves work efficiency but also reduces labor intensity. Through the above mechanism, the assembly of the base plate is completed, improving work efficiency, and the demolding of the outer cylinder and the inner cylinder is realized, which also improves work efficiency and reduces labor intensity.
