[0047] The steel mesh is a cylindrical grid body formed by welding straight steel strands and round welding wires. When applying preload, it is achieved by stretching the steel strands. After the steel mesh is fully mixed with cement, a cement column will be formed. The mold 7 has an upper and lower part. During processing, the mold will be closed and fixed by bolts on the outside so that the internal structure will no longer move. During processing, the end face structure 2 is set on the bearing component 31, and the traction component 32 is set on the bearing component 31.

During the movement, the limit structure 5 is used to limit the position. After the processing is completed, the cement column is separated from the mold 7 by the retraction structure 4, and then the cement column is taken out and set on the transposition structure 6 by the withdrawal rope 8, so that the preload is stretched. Avoid being fixed with bolts, the installation and disassembly process becomes very fast, reducing the processing time, using the withdrawal rope 8 to quickly take out the cement column and separate the cement column from the mold 7, reducing energy loss and speeding up the work speed.
