Well Foundation Is Also Known As

Well foundation is a type of deep foundation which is generally provided below the water level for bridges. Cassions or well have been in use for foundations of bridges and other structures since Roman and Mughal periods. The term ‘cassion’ is derived from the French word caisse which means box or chest.

Is Well foundation and caisson same?

in particular, they are used as foundations for bridges. Caissons are usually prefabricated above the ground level and above the water level and sunk to the bearing level as one single unit. when the process of fabrication and sinking proceed simultaneously they are referred to as well foundation.

What is the difference between pile foundation and well foundation?

The main difference between a well and a pile foundation: The pile is versatile like a beam under horizontal load. The well undergoes rigorous body movement below such load.

Which of the following is a part of well foundation?

Components of Well Foundation

Steining is normally of reinforced concrete. Well Curb: It is the wedge-shaped RCC ring beam located at the lower portion of the well steining provided to facilitate sinking. Bottom Plug: After the well is sunk to the required depth, the base of the well is plugged with concrete.

What is well in civil engineering?

Wells can be defined as. “A hole made for collecting underground water.” Or. ” A shaft sunk into the ground to obtain water, oil or gas.”

What is caisson in well foundation?

What is well sinking?

Well sinking operation involves lowering of well by dredging in the dredge hole with the help of plate grab in the case of soft strata like sandy silt, soft clay, sandy clay, dense sand etc. Levels and alignment of well shall be checked periodically at every 0.5m of sinking.

What is tilt and shift in well foundation?

When the well is moved away horizontally from the desired position, it is called shifting of the well foundation. When the well is sloped against vertical alignment, it is called tilting of the well foundation.

Why sand is filled in well foundation?

Sand filling provide stability of well, reduce tensile stress produced by bending moment and distributes the load of super structure on to the bottom plug. Sand filling relieves load to steining to some extent.

How well foundation is constructed?

Well foundations are constructed in stages by sinking under self-weight as well as dredging the soil inside the dredge hole and on the sides outside. The first step in the construction of a well foundation is to lay the cutting edge and well curb.
