Problem in bored pile
- 2. SCOPE 1. EXCAVATION OF PILE BORE 2. DESIGN AND LOWERING OF PILE REINFORCEMENT 3. CONCRETING THE PILE
- 4. 2.DESIGN AND LOWERING OF PILE REINFORCEMENT 2.1 DESIGN OF PILE REINFORCEMENT 2.2 LOWERING OF PILE REINFORCEMENT
- 5. 3. CONCRETING THE PILE BORE 3.1 QUALITY OF CONCRETE 3.2 PLACING OF CONCRETE 3.3 EXTRACTING TEMPORAEY CASING 3.4 PROBLEMS IN SOFT GROUND
- 7. WET DRILLING BY REVERSE ROTARY
- 9. OVER BREAK
- 11. 1.5 EFFECT OF W/T In dry drilling of borehole ingress of small quantity of water from sides of the borehole reduces the Skin Friction and from the bottom of borehole reduces the End Bearing. In this condition concreting should be carried out with Tremmie Pipe otherwise segregation of concrete may occur as shown in Fig. SEGREGATION OF CONCRETE
- 15. LAP OF CAGE
- 17. SLUMP TEST
- 21. CONDUCTOR PIPE
- 22. 3.4 PROBLEMS IN SOFT GROUND In soft ground having undrained shear strength less than 15kn/m 2 causing the squeezing of the pile section near the head because lateral pressure of soil is more than the lateral pressure of concrete as shown in Fig. SQUEEZING OF THE PILE SECTION
- 23. CONCLUSIONS Full time supervision of pile construction should be carried out by an experienced Engineer which gives us the designed pile capacity
- 25. ANY QUESTION?
