In geotechnical engineering, a caisson is a watertight retaining structure which is used, for example, to work on the foundations of a bridge spring, for the construction of a concrete dam or for repair Of ships. These are constructed in such a way that the water can be pumped out, keeping the working environment dry. When the springs are to be constructed using an open drawer and it is impractical to reach the proper ground, the friction stacks can be driven to form a suitable sub-base. These batteries are connected by a foundation pad on which the column spring rises.
Caisson Foundation is also known as Pier Foundation. Caisson is a hollow cylinder or box that sinks into the ground to a depth specified by auguring a deep hole in the strata. The cylinder or box is again filled with concrete, thus creating the base. This type of foundation is most commonly used when bridge piers and other foundations are built under water bodies, since the drawers can be floated to the right places and then sunk in place using concrete.

This type of foundation will keep the floors below the building or structure moving vertically. Since the ground will settle over time, the building or structure above the ground will also settle. This can cause great structural damage. Since a foundation drawer is drilled into the ground and large cylinders of full concrete are placed on the floor instead of at the top, the laying of the floor will not cause many difficulties for the building or structure.
Advantages of Caisson Foundations
There are many advantages to using a drawer foundation. Here is a list of the main advantages of the foundations.
• Easily adaptable to different site conditions. This means that no matter where the structure is being built, the drawers can easily be put into place. The most difficult part of placing them is drilling the holes.
• High axial and lateral load capacity for these foundations. The weight of the structure can be easily supported by the pillars and is very robust.
• They are very economical. The cost of drilling and installing drawers is minimal compared to the cost of establishing a traditional base.
• Springs minimize the need for battery plugs. Because the pillars are filled with concrete, battery lids are not really necessary.
• The base of the drawer will reduce vibrations and will have a little less noise. Since the foundation is based on springs, there are fewer vibrations that will disrupt the structure.
