What is prestressed spun pile?
What is prestressed spun pile?
Spun pile is a prestressed concrete pile with circular hollow section. This overview is related to methods of increasing the strength and reliability of spun pile due to earthquake loads, either by modifying the longitudinal reinforcement and confinement.
Why use spun piles?
SPECIAL FEATURES OF SPUN CONCRETE PILES : Spinning results in denser concrete, reduces water cement ratio and hence increases concrete strength further. High flexural strength. Absence of torsion cracking. High resistance to corrosion especially from sea water.
What are the advantages of precast concrete piles?
Precast foundation piles have many advantages: being much faster foundation time, highest foundation quality, real-time load test etc., but most importantly precast piling is a cost effective and environmental friendly method to install concrete foundation.
How do you install bored piles?
Installing a bored pile starts with drilling a vertical hole into the soil, using a bored piling machine. The machine can be outfitted with specially designed drilling tools, buckets, and grabs to remove the soil and rock. Piles can be drilled to a depth of up to 60 meters and a diameter of up to 2.4 meters.
How are precast concrete piles made?
Piles are manufactured off-site in standard lengths, and driven into the ground using self-erecting hydraulic piling rigs with hydraulic hammers until the required depth/resistance is reached. Piles can be jointed using the Multijoint (Mechanical Interlocking Joint) or the UNIjoint (for compressive loading).
What is pre-stressed concrete circular spun piles?
Pre-stressed Concrete Circular Spun Piles are an International phenomenon and in use all over the World particularly in Germany, Japan, Malaysia, Indonesia, Taiwan and Korea for quite some time. HBL Power Systems Ltd is a pioneer in manufacturing of High Strength Pre-Stressed Spun Concrete Products in India.
Who is the leading manufacturer of pre stressed concrete in India?
HBL Power Systems Ltd is a pioneer in manufacturing of High Strength Pre-Stressed Spun Concrete Products in India. High Performance, High Strength Pre-Stressed Spun Concrete Piles offers an economical deep foundation system with consistent and superior quality compared to cast in situ & other concrete piles.
What is a spun cast pile?
Spun Cast Pile Introduction SPUN CAST CYLINDER PILE The hollow, prestressed concrete spun cast cylinder pile is a unique structural member. Bridge Bent with precast Cap In thousands of elevated structures all over the world, it functions as both foundation and pier or column. It supports high axial and bending loads over
What is the maximum capacity of a concrete pile?
Pile capacities Piles driven into the weathered gran- ite with the proper size hammer will develop the maximum pile capacity available. Normally pile capacities ranging from 75 to 250 tons are speci- fied for driven prestressed concrete piles used in building foundations.
