What is Pile Cap?
Pile cap is a structure which is built when single pile will not be able to take the load of the overlying structure
This is generally built when there are some restrictions on the size of a single pile
Pile cap is like a slab below which there are various piles or a group of piles . Such that they combine to act as a single pile which withstand the load from the superstructure or column.
How to Find Volume of Concrete in a Triangular Pile Cap?
Let us calculate the volume of concrete in a triangular pile foundation having 3 nos. of the pile, as shown below. Foundation Pilings
Given data:
Pile diameter = 0.6m.( d )
No. of piles = 3 nos.
Length of pile = 16m. (h )
Depth of the pile cap = 0.9m.(D )
Solution:
The volume of concrete in the piles
= 3nos.× πr2 h
Here,
r = radius of the pile.
= d ÷ 2
= 0.6m ÷ 2
= 0.3m.
h = length of the pile.
The volume of concrete in piles
= 3nos. × 3.142 × (0.3m)2 × 16m.
= 13.57 cum.
The volume of concrete in the pile cap :
The volume of pile cap concrete
= Surface area (A ) × depth ( D )
First, let us calculate the sectional area (A1) of rectangle ABCD, as shown in the below drawing.
Area of rectangle ABCD (A1)
=L × B
= 2.2m × 2.0m
= 4.4 sqm.
To get the surface area ( A) of the pile cap, we have to deduct the area of triangles AEF & GDH from the rectangle area.
Here,
Triangle AEF = triangle GDH
Area of triangle AEF
= 0.5 × base × height.
= 0.5 × side AE × side AF
Side AE
= [ ( 1/2 ×side BC ) – (1/2 × side EG )]
= [ ( 1/2 ×2m. ) – (1/2 × 0.6m. )]
= [ 1m – 0.3 m ]
= 0.7m.
Side AF
= side AB – side FB
= 2.2m – 0.7m
= 1.5m.
I have redrawn the triangle, with the calculated length of the sides AF & AE as shown below.
Area of triangle AEF
