PC Well Method
PC Well Method
The PC well method involves stacking cylindrical single blocks at the construction site while introducing prestress using a post-tensioning method. The interior is excavated using various excavation machines such as hammer grabs, and ground anchors are driven and installed to a specified depth as a reaction force. The single blocks are equipped with PC copper rods, rebar placement holes, grout injection ports, and anchor plates, designed to standardize work at the construction site. The excavation methods include in-bucket excavation with hammer grab buckets and undercutting with widening excavators, making it suitable for a wide range of soil types. There are two types of PC wells: PC structure and PPRC structure. Features of the method: 1. It uses factory-manufactured precast components, ensuring thorough quality control, making it a highly reliable method. 2. Construction management is easy. 3. Since it is installed using a jacking method, it has minimal impact on the surrounding ground and is suitable for close-proximity construction. 4. It allows for low vibration, low noise, and high safety during construction. 5. It does not require temporary closures or island construction even for underwater work. 6. The construction accuracy is excellent. 7. The construction period can be shortened.
