What is spun concrete pile?
Spun pile is one of the types of piles are widely used in the world construction, for example in building and bridge. Spun pile is a prestressed concrete pile with circular hollow section. Thus, by this overview can be obtained new idea for the next research to improve the performance of spun pile carry seismic loads.
Why use spun piles?
Spun piles are suitable for foundation works of buildings, residences, factories that are required high foundation strength which can help to reduce vibration when pile driving because the pile is round and hollow, thus reducing soil pressure during installation.
What is preliminary pile test?
Preliminary pile (for failure load test) : a pile installed before the commencement of the main piling works or specific pile of the Works for the purpose of establishing the suitability of pile and for confirming its design dimension and bearing capacity.
What is prestressed concrete pile?
Prestressed concrete piles are vital elements in the founda- tions of buildings, bridges and marine structures throughout the world. They usually vary in size from 12 in. (305 mm) square piles used in building foundations to 66 in. (1680 mm) diameter cylindrical piles used in marine structures and bridges.
What is driven pile?
Driven piles (precast piles) are prefabricated elements (timber, steel or concrete), which are driven into the ground by percussion, pressing or vibration, using proper machinery.
How is pile tested?
Static load testing, where the pile is loaded gradually via a load cell from either reaction piles, kentledge or surface footings. This method of testing is generally considered the most reliable method of testing piles and most closely resembles the working loading conditions on the piles.
Which piles are most widely used?
Cast in place concrete piles are the most type commonly used for foundations due to the great diversity available for pouring concrete and the introduction of the pile into the soil. Driving and drilling piles are two types of cast in place concrete piles.
Why are concrete piles used?
Precast concrete piles are used for constructing various civil engineering and construction structures. They are customisable via pile cropper, suitable across a huge range of applications and ground conditions. This is especially true when reducing these items to the recommended pile cut off level.
What is PDA test pile?
The Pile Driving Analyzer® (PDA) system is the most widely employed system for Dynamic Load Testing and Pile Driving Monitoring in the world. High Strain Dynamic Load Tests, also called PDA tests, assess the capacity of several piles in a single day.
