The offered bored cast-in-situ piles services are delivered to lay the foundations of industrial complexes, bridges, and flyovers. Forces and velocities occurring along a pile during ram impact are complementary quantities, related to each other by pile characteristics and soil parameters. Driven and cast - in - situ piles - Cast in situ pile is formed by driving a closed ended tubular section to form a void then filling the void with concrete whilst withdrawing the section. In granular soils the bearing capacity of the pile improves by compaction of the surrounding soil due to the vibratory action of the casing that is used to install the pile. To ensure the proper contact between base of pile and rock surface, it is needed to socket the pile into hard rock by cutting through weathered and soft rock and by cutting the hard rock for a reasonable depth mainly to get the level surface of rock and. Pile casing is then driven into the soil. by pipe as well as concrete. The procedure of installing a driven and cast-in-situ pile is as follows: A steel shell is driven into the ground with the aid of a mandrel inserted into the shell. Among cast in situ piles, there is driven cast in situ piles where a steel shoe is driven into the ground along with the casing and later the hole is filled up with concrete.
