Micro Pile to Concrete Connection IWM 2004 in TOKYO Takashi Yamane KYOKUTO CORPORATION TOKYO JAPAN Takashi Yamane KYOKUTO CORPORATION TOKYO JAPAN

Micro Pile to Concrete Connection Contents 1. Design Requirements 2. Standard System for Cast-in-Place (CIP) Concrete 3. Splice Cap System for Precast Concrete

Design Requirements 1. Punching in Concrete 2. Compression and Tension in Concrete 3. Strength in Pile Head Itself

Application

Splice Cap System for Precast - Cap Type Advantages of Precast concrete: * Save construction time and cost * High quality in concrete

Splice Cap System for Precast Through Type

Loading Test Pull Out Pmax=300 ton ｆor 7” Pile

Loading Test Alternative Horizontal Load Mmax = 220 kN-m for 7” pile

Application (1) Road in Mountain Shoulder Reinforcement, Rock Shed, Snow Shed

Application (2) Retaining Wall

Application (3) Plank Bridge

Conclusions 1. The advantages of precast concrete can be fully used with Splice Cape System. 2. More loading test is planned for various pile diameters. 3. We are looking for more applications.
