Large diameter PHC piles with a diameter of Ø 700 or more are
efficient for handling high vertical and horizontal loads.

Features

Due to the development of construction and engineering technology, and the efficient use of land, the increase in super high-rise buildings, the stabilization of load-bearing walls, and the reduction of construction costs have led to the introduction of large diameter piles to respond to market changes.

They can enhance seismic design using Rahmen structures.
They have strengths in the design of high-rise complex buildings.
They offer economic benefits by reducing material costs compared to the RCD method.

Effects of Large Diameter Piles

01 Can replace cast-in-place pile methods on-site
02 Provides consistent quality as a precast concrete
03 Reduces construction time and material costs
04 Provides the capability to replace large diameter steel pipe piles with large diameter composite piles
05 Reduces the number of piles needed due to high bearing capacity
06 Can be widely applied to all pile construction projects

Application Fields of Large Diameter Piles

Plants
Ports
Land bridges
High-rise buildings
Marine bridges
Super-tall buildings

Comparison of Large Diameter Piles and Cast-in-Place Piles

Type	Large-Diameter PHC Piles	RC Piles
Division
Advantages	- Good quality of the pile body - Saves construction costs - Shortens construction period - Can be widely used for all pile construction	Completed as a single, long pile without joints
Disadvantages	Joints are required as the depth increases	- Difficult to manage construction, making quality control challenging - Increases construction and material costs - Extends construction period - Difficult to ensure bearing capacity due to issues like rebar framework floating
Method	SIP, SDA,(DRA), PIB	Earth drill, All casing, RCD
