An Easy Guide on the Types of Foundation
While an abode provides you the comfort of reviving your body and mind after a hectic schedule, an office offers you the opportunity to escalate your skill in a particular field or more than that. On the other side, a bridge signifies the progress of an era. Be it a house, an office, a hospital, a bridge or something else, foundation is the fundamental part of a construction.
Foundation is the lowest part that transmits the overall load into the soil. The primary function that it serves is to distribute the weight evenly on the soil, and thus, makes the building strong.
The classifications of foundation in civil engineering are:
1. Shallow foundation
It is a kind of foundation where you will find the foundation below the lowest part of a particular structure. The depth is less than or equal to its width. There are three types of shallow foundation including:
i) Spread footing
ii) Combined footings
iii) Raft or mat foundation
i) Spread footings :
A wide base of foundation in order to transmit the load to the mud over a wide area.
ii) Combined footings:
A common footings that is provided to two columns that can be either trapezoidal or rectangular.
iii) Raft foundation:
Consists of dense reinforced concrete slab, it covers the total bottom area of the structure.
2. Deep foundation:
In this kind of foundation, the foundation is placed at the profound depth of the ground level. This type of foundation construction is very easy.
It is mainly classified into three categories:
i) Pile construction
iii) Caisson foundation
i) Pile construction:
In it a slender member of concrete or wood or steel is inserted into the ground to transfer the load of a structure.
Based on the function, it is classified into:
i) Friction piles
ii) Bearing piles
iii) Anchor piles
iv) Sheet piles
v) Batter piles
vi) Fender piles
vii) Compaction piles
On the other side, based on material, it is classified into:
i) Timber piles
ii) Concrete piles
iii) Steel piles
It is a temporary structure that excludes the water to enable the construction on the dry surface. The classifications include:
i) Earthen cofferdams
ii) Rock-fill cofferdams
iii) Single-walled cofferdams
iv) Double- walled cofferdams
v) Crib cofferdams
vi) Cellular cofferdams
iii) Caisson foundation:
Made of wood, steel, it is a watertight structure. There are three types of caissons:
i) Open caisson
ii) Box caisson
iii) Pneumatic caisson
As now, you have a clear view about the types of foundations, classifications, and the materials that are used to build it, it would be easy for you to understand why your engineer chooses a particular foundation than other ones and you can discuss its usefulness with the professional. Create a strong base for your property with the expert.
