How is a cast-in-place concrete pile constructed?

A cast-in-place concrete pile is constructed by driving a steel shell into the ground and then filling it with concrete. This method is effective because the steel shell provides immediate support and helps to maintain the shape of the pile during the pouring process. Once the shell is in place, concrete is poured into it, creating a solid and integrated foundation element that is well-suited for applications requiring deep foundation support.

This approach allows for high structural integrity and can be adapted to various soil conditions. The use of a steel shell also helps to limit the displacement of soil, leading to less disturbance of the surrounding area compared to other methods.

The other construction methods typically refer to different types of piling or foundation techniques that do not fit the definition of cast-in-place concrete piles. For instance, drilling a hole and pouring concrete relates more closely to bored piles, while assembling precast segments refers to a different construction method altogether. Mixing concrete on-site and pouring it into molds usually applies to other forms of concrete work, rather than specifically to cast-in-place piles.
