Subsequently the portion pertaining to underreamed pile foundations was deleted and now covered in IS 2911 (Part 3) : 1980 'Code of practice for design and construction of pile foundations: Part 3 Underreamed piles (first revision)'.
Get PricePrecast concrete pile is the preferred choice for highrise building foundation, since the product can provide the required bearing capacity. Implementation of this foundation is practical and economical with guaranteed quality as casting is done at our factory.
Get PricePile foundations are used when the underlying soils are incapable of resisting the loads from the structure. The piling is placed in the ground through poor quality materials to bear on competent soils. The piles are either driven into the ground or holes and filled with reinforced concrete. The piles transfer the load by bearing on competent
Get PriceIn service, the cylinder pile is virtually maintenance free. A special concrete is cast by a process unique to cylinder piles which achieves a very high density and low porosity. The pile is virtually impervious to moisture. Cylinder Piles in marine structures since 1950 show no .
Get PriceConcrete Piles Concrete piles in New York are precast and prestressed. The piles are cast in a precasting plant and then transported to the site. This creates a pile made of high quality concrete under controlled casting and curing conditions. The process is overseen by an inspector assigned to that plant.
Get PriceAn Olivier Pile is screwed into the ground without vibration, the soil is displaced sideways. No soil is transported to the surface. The rotary pressure is compared with the results of the cone penetration test.; The rotary head with a maximum torque of 55 ton meter is pulled up and down along an adjustable leader, which is strong enough to hold all the forces.
Get PriceConcrete Piles Concrete piles are the type of pile foundation that essentially consists of concrete as the chief element. Concrete piles may be further classified into Precast concrete piles and castinplace concrete piles. They are briefly described as follows: a. PreCast Concrete Piles. Precast concrete piles are one of the most commonly ...
