Pre-stressed concrete pole steel mould is used for electronic concrete pole making. Its mainly manufacture technology is longitudinal tensioning the steel wire, and queezing out the excess water from the concrete under the centrifugal force. Thus, it can greatly improve the concrete density and strength.

 

1. Welding technique, which can highly enhance the smooth finish of the mould wall, and eliminate uneven traces of rivet holes. So the concrete poles’ appearance will be improved significantly;

2. The cylinder is changed to U-longitudinal stiffener, it can greatly increase the stiffness and anti-bending degree of the mould;

3. Install the slot with plastic sealing strip, in order to prevent leakage to ensure quality.

 

1. Conical steel mold

2. Equal diameter steel mould

 

Steel mold inner diameter (mm)	Length (m)	Tread (m)	Running wheel diameter (mm)
300	4.5～9	2	600
400	4.5～9	2	650
500	4.5～9	2	750

 

1. The steel mould works together with pole spinning machine. The steel mould should be placed onto the spinning machine smoothly.

2. Put the slurry into the mould and rotate in different directions under the motor driven.

3. In this process, the redundant water in the concrete is released by the force of centrifugal, and the concrete is dense and high strength.
