1. PRETENSIONED SPUN CONCRETE PILES

2. PROJEK CEKAP THE GROUN D ENGINEERING SPECIALIST Projek Cekap (M) Sdn . Bhd. has been involved in  Spun Pile foundation services for the construction industry since it was incorporated. They have since been providing piling services to buildings and roadworks undertaken by both private and government bodies. PROJECT THE USED PRETENSIONED SPUN CONCRETE PILES: Kuala Lumpur International Airport 2, Sepang Malaysia

3. FUNCTIONS OF PRETENSIONED SPUN CONCRETE PILE Transfers the loads from structures to the hard strata, rocks or soil with high bearing capacity. To resist vertical, lateral and uplift load. It acts as end bearing pile. To install loose cohesion soil through displacement and vibration. Convenient method of foundation for works over water and on sloping site. To control the settlements which can be accompanied by surface foundations. Increase the factor of safety for heavy loads buildings.

4. MANUFACTURING PROCESS OF PRETENSIONED SPUN CONCRETE PILE 1 2 3 BUTTON HEADING BENDING AND INSTALLATION OF CIRCULAR REINFORCEMENT CAGE INSTALLATION AND PREPARATION CYLINDRAL MOULD

5. MANUFACTURING PROCESS OF PRETENSIONED SPUN CONCRETE PILE 4 5 6 7 PUMPING OF CONCRETE INTO THE MOULD THROUGH A PUMPING MACHINE CURING OF CONCRETE THROUGH SPINNING AND STEAM CURING DEMOULDING, TESTING AND INSPECTION OF SET CONCRETE STORAGE OF CONCRETE AND TRANSPORTING TO SITE

6. MANUFACTURING PROCESS OF PRETENSIONED SPUN CONCRETE PILE 4 5 6 7 POSITIONING OF MACHINERY AND PILE ENSURE THE PILE IS VERTICALLY STRAIGHT + HAMMERING OF PILE HAMMERING PROCESS CONTINUES UNTIL THE PENETRATION DEPTH IS REACHED IF THE DEPTH REQUIRED IS MORE THAN 12m JOINTING AND WELDING WORKS IS REQUIRED

7. PROBLEMS THAT CAN OCCUR DURING THE CONSTRUCTION PROCESS PILE DRIVING DEEPER THAN THE DESIRE DEPTH . LATERAL MOVEMENT OF PREVIOUSLY INSTALLED PILES WHEN DRIVING NEW PILES. PILE OBSTRUCTIONS AT DEPTH. BLOW COUNT SIGNIFICANTLY LOWER THAN EXPECTED. Desired Depth

8. ADVANTAGES CAN EASILY BE JOINTED TO ANY COMBINATION OF LENGTH AS PER LENGTH VERSATILE HIGH FLEXURAL STRENGTH SAVES TIME LESS PERMEABLE THAN NORMAL REINFORCED CONCRETE PILES MINIMAL STORAGE SPACE DISPLACEMENT AND VIBRATION EFFECT ON SOIL COMPACTION = > < CANNOT BE DRIVEN WHERE HEADROOM IS LIMITED POSSIBLE TO GET DAMAGES E.G. CRACKS NOISE DISTURBANCE IF DRY HAMMER IS USED VIBRATION DISTURBS ADJACENT STRUCTURES ADVANTAGES AND DISADVANTAGES OF PRETENSIONED CONCRETE SPUN PILES DISADVANTAGES
