The number of the connecting part 6 is not limited and is arranged according to the diameter of the concrete cylinder 12.
[0035] Specifically, as shown in the utility model, Figure 2 As shown in the utility model, the protective layer 2 comprises a heat preservation layer 2.1, and the heat preservation layer 2.1 is arranged close to the outer side of the concrete cylinder 12.

In the embodiment, the heating layer 2.2 is provided as an electric heating blanket, which accelerates the increase of the concrete strength by external heating. After the concrete is finally cured, a large amount of heat is released inside the concrete, and the heating layer 2.2 can make the temperature difference between the surface and the inside of the concrete similar. The heating layer 2.2 involves power supply, so a cable reel needs to be placed on the slip-form device 10, and the power is supplied by a power distribution box below.
[0037] Preferably, the heating layer 2.2 is provided with a blocking layer 2.3 on the side away from the heat preservation layer 2.1.

Each fire source 3 is connected with the smoke exhaust pipe 9, the smoke exhaust pipe 9 connects the fire sources 3, and is arranged around the concrete cylinder 12 to increase the heat radiation area. The exhaust gas generated by the fire source 3 is discharged from the entrance 13 of the concrete cylinder 12 by the smoke exhaust pipe 9. The height of the smoke exhaust pipe 9 at the inner side of the concrete cylinder 12 is higher than the height of the smoke exhaust pipe 9 at the entrance 13, so as to reduce the overflow of hot air.
