This system is advantageous when compared with the traditional fixed molds, which does not allow changes in the amount, and not even in the variation of the dimensions of the piles. The WCH system of tensioned blades allows the production of the following square piles:
In this system the steel blades are manually positioned on the concrete floor, then the blades are individually tensioned through the hydraulic Jack, until reaches the desired working tension. The crosspiece guide is positioned on the blades in the determined places, after this process, just spread the concrete.
If there is need for replacement of the production for piles with other dimensions, simply remove the blades and replace them by others.
• Safe and financially feasible for those companies who are starting their activities in manufacturing prestressed or reinforced prefabricated square piles.
