step four: then taking out a pressurizing pipe of the air compression equipment, sleeving a one-way valve, injecting high-pressure gas into the diversion trench (20), extending a telescopic rod (22) out of the inlet and outlet holes along a piston pipe (21) and a guide rod (27) under the sealing action of a sealing piston (23), contacting with the inside of a conical trench of a mounting disc (24), and further pressurizing the telescopic rod (22), wherein the more firmly the circulating steel die (3) is connected with the supporting die (1) under the conical surface action of the conical trench, the less loosening can be caused under the action of the one-way valve (19), and the operation is simple and convenient;
step five: when the embedded pipe (8) is required to be disassembled, the limiting block (15) is contacted with the supporting die (1) under the action of the inclined plane and compressed into the spring groove (13), when the connecting rod (7) is separated from the supporting die (1), the connecting rod can enter the pipe groove of the embedded pipe (8) along with the connecting rod, the embedded pipe (8) is not directly stretched out and hooked, the disassembly is convenient, and when the embedded pipe (8) is installed in the same way, one side of the limiting block (15) is directly sleeved, and the preset position is kept under the action of the limiting block (15) to wait for use;
step six: after the die is removed, the circulating steel die (3) waits for the next use, the formed concrete layer (4) has an excellent stair structure, the surface is smooth, the lower end is folded, the weight is low, and the finished product is transported to a construction position by matching with the holes of the embedded pipe (8) for normal assembly and use.
