2. 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

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

4. Application

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

6. Splice Cap System for Precast Through Type

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

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

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

10. Application (2) Retaining Wall

11. Application (3) Plank Bridge

12. 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.

13. Thank You !
