Caissons are watertight structures made up of wood, steel or reinforced concrete built above the ground level and then sunken into the ground. Pile foundation is a type of deep foundation, in which the loads are taken to a low level by means of vertical timber, concrete or steel.
Piles, piers, and caissons all serve the same cause: to switch loads to deeper soil or rock layers. However, they fluctuate in construction strategies, materials, and design components. Builders drive piles into the ground.
Drilled shafts (also called caissons, drilled piers or bored piles) have proven to be a cost effective, excellent performing, deep foundation system, that is utilized world-wide. Typically they are used for bridges and large structures, where large loads and lateral resistance are major factors.
Caissons are constructed in such a way that the water can be pumped out, keeping the work environment dry. When piers are being built using an open caisson, and it is not practical to reach suitable soil, friction pilings may be driven to form a suitable sub-foundation.
The types of pile foundation are end-bearing piles, friction piles, compaction piles, anchor piles, tension or uplift piles, sheet and batter piles, etc. The types of pier foundations are masonry or concrete piers and drilled caissons.
2 de mar. de 2021 · Two popular options for deep foundations are helical piles and drilled shafts, also known as drilled piers or caissons. A helical pile is a displacement foundation. Helical piles are screwed into the ground with minimal soil disturbance until the helix plates are located into stable load-bearing soil. A helical pile develops capacity ...
Drilled shafts are high-capacity deep foundation systems, also known as drilled piers, caissons, bored piles, or cast-in-drilled-hole piles (CIDH). Common uses. Structural support. Slope stabilization. Earth retention for retaining walls and sound barriers. Process.
