TYPES OF PILES BASED ON CONSTRUCTION METHOD

There are three types of pile foundations according to their construction methods: 1. Driven piles, 2. Cast-in-situ piles, and 3. Driven and cast-in-situ piles. Driven Pile Foundations: Driven pile foundations can be made from concrete, steel or timber. These piles are prefabricated before placing at ...

PILE FOUNDATION SELECTION BASED ON SOIL CONDITIONS

Pile foundation selection depends on the soil data received from soil exploration bore holes at different depths. Selection of pile foundation types and length depends on following conditions:Soil conditions Loads from structures Nature of loads Number of piles to be used Cost of constructionThere are ...

CAPACITY OF PILE GROUP AND EFFICIENCY

Capacity of pile group is the sum of the individual capacities of piles, but it is influenced by the spacing between the piles. Piles are driven generally in groups in regular pattern to support the structural loads. The structural load is ...

PILE LOAD CAPACITY CALCULATION

Pile load capacity calculation is done to find the ultimate load the pile foundation can support when loaded. It is also known as the bearing capacity of piles. Pile load capacity calculation is done for single pile or a group ...

LOAD TESTS ON PILES

Load tests on piles are conducted on completion of 28 days after casting of piles. Two types of tests namely initial and routine tests, for each type of loading viz. vertical, horizontal (lateral) pull out, are performed on piles. ...

INTEGRITY TESTING OF CONCRETE PILES

Majority of cast-in-situ pile fails because of defective pile shaft necking, intrusion of foreign matters and improper toe formation due to contamination of concrete at base with soil particles, discontinuity of concrete, leaching of concrete due to high water current, ...
