[0025] The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process, and the specific work is as follows.

[0026] Step 1: After the first outer plates 11 in the main structure 1 are relatively fitted, they are butt-jointed and limited by the docking component 14 on one of the first outer plates 11; that is, rotate the waist seat 141 to move in the transfer groove 44, place both ends of the waist seat 141 in the transfer grooves 44 of the two first outer plates 11 respectively, and then rotate the first bolt 142 to fix the waist seat 141 and install the second bolt 143 located in the top groove 45 to tightly fix the waist seat 141 again. Then, the four first outer plates 11 are butt-jointed in turn to form the mold of the cylindrical pier. Step 2: When in use for pouring, the feeding port 42 in the groove 41 can be opened, that is, move the locking rod 133 in the feeding component 13, rotate the locking rod 133 from the first locking groove 43 and apply a downward force, lower one end of the locking rod 133 and compress the spring 134, and detach one end of the locking rod 133 from the locking claw 132 to disassemble and open the inner plate 131 to open the feeding port 42, and pour or vibrate the concrete below through the feeding port 42; install the inner plate 131 by limiting and embedding it in the feeding port 42 and fixing it by locking with the locking rod 133. Step 3: When it is necessary to increase the height of the main structure 1, after the four first outer plates 11 of the main structure 1 are assembled, they are placed on another main structure 1, that is, insert the locking seat 12 of the first outer plate 11 into the seat groove 48 to fit, and limit the locking seat 12 in the seat groove 48 by installing the third bolt 144 for assembly and stacking to increase the height. Step 4: Installing the top platform structure 2 can form a platform floor at the top after the assembly of the main structure 1 for manual standing construction. That is, according to the actual steel bar spacing requirements, adjust the support arm 22 to move within the adjustment groove 51 of the platform 21 and fix the support arm 22 with the fourth bolt 23. Adjust the positions of the limit seat 24 and the support arm 22, pass the support arm 22 between two perpendicular steel bars, then lower it and insert the limit seat 24 into the seat groove 48 for limit placement, and set the platform 21 between the first outer plates 11. And after inserting the T-shaped end of the lifting arm 25 into the fixed jack 46 and then flipping it, make the upper and lower ends of one end of the T-shaped lifting arm 25 located on the upper and lower sides of the fixed jack 46, that is, one end of the lifting arm 25 is located in the fixed slot 47, then the lifting arm 25 can be clamped at the fixed jack 46 part, making the lifting arm 25 perpendicular to the first outer plate 11. Then place both ends of the corresponding fitting outer pedal 26 at the middle of the lifting arm 25, and insert the fifth bolt 27 into the retaining groove 52 of the outer pedal 26 for limit, then an arc-shaped pedal can be formed outside the first outer plate 11 for workers to stand on.

Three main structures 1 can be assembled to form a mold with an opening, and the openings of the two assembled main structures 1 are opposite to each other and connected by means of the auxiliary component 3 to form the connection of the two cylindrical piers. By setting seat plates 32 at both ends of the docking plate 31 and docking and assembling with the first outer plate 11 through the seat plates 32 to achieve connection. If the height needs to be increased, the fitting seat 62 can be inserted into the fitting groove 61 and fixed tightly with the sixth bolt 33 for assembly and stacking. If a single cylindrical pier needs to be connected to a rectangular pier body, three main structures 1 can be assembled and then the docking plate 31 seat and the docking plate 31 are set, and side baffles 34 are set between the other ends of the docking plates 31. The side baffles 34 are fixed by inserting the docking claws 35 into the fitting groove 61 with the sixth bolt 33.
