Monday Tech Talk – Construction Piling
This Monday Tech Talk will focus on Construction Piling as a topic. Piling is used in the construction of buildings, bridges and other structures when the soil might not be able to support the weight necessary for the structure. Piling is therefore used for these deep foundations to ensure the framework of buildings/structures is supported both above ground and underground.
This technique is used in the construction of bridges, buildings, and other structures when the soil present at the premises is incapable of supporting the necessary weight for the structure. Piling in construction proves to be very helpful in setting deep foundations for the construction work
A pile is a long structure, in the shape of a cylinder, from steady material like concrete, that go beneath the ground in order to build structures on top of it.
What are Pile Foundations?
Pile foundations have piles that connect to a pile cap, to hold more loads than one pile can carry. Pile caps are constructed to hold the pile and superstructure together at the ground level or below the ground level while transferring loads of the structure to the foundation. Generally, pile caps are constructed to connect one or more piles. Dimensions of the pile caps are decided based on the loads and connecting arrangement of the structure and the pile foundation.
Loads Acting on Piles
Following are the loads which are to be taken into account while designing a pile.
- Direct vertical load coming from the superstructure.
- Impact stresses developed during the process of pile driving.
- Stresses developed during handling operations.
- Bending stress developed due to the curvature of a pile.
- Bending stresses developed due to the abnormality of loads on the pile.
- Lateral forces due to the wind, waves, currents of water, etc.
- Force due to the uplift pressure.
- Earthquake forces.
