PPRC Well Press-in Method
PPRC Well Press-in Method
PPRC Well Press-in is one of building methods of underground columnar concrete foundation by pressing a precast segmental well into the ground using the guide frame with hydraulic jacks. PPRC Well Press-in Method uses deformed reinforcing bars as tensile steel element. To set precast segment in position, temporary post-tensioning bars are stressed at each joint section.
This method is safer and more economical, and can keep noise and vibration to minimum compared to conventional concrete foundation building methods.
