In this Article today we will talk about the Volume of Concrete in Triangular Pile | Pile Concrete Calculation Formula | Triangular Pile Cap Volume | Piles Foundation Types | Concrete Piling | Concrete Piles Construction | Concrete Quantity of Pile | Pile Concrete Calculator | Foundation Pilings
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 witstand the load from the superstructure or column. Concrete Piling
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
Pile diameter = 0.6m.( d )
No. of piles = 3 nos.
Length of pile = 16m. (h )
Depth of the pile cap = 0.9m.(D )
The volume of concrete in the piles
= 3nos.× πr2 h
r = radius of the pile.
= d ÷ 2
= 0.6m ÷ 2
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.
Triangle AEF = triangle GDH
Area of triangle AEF
= 0.5 × base × height.
= 0.5 × side AE × side AF
= [ ( 1/2 ×side BC ) – (1/2 × side EG )]
= [ ( 1/2 ×2m. ) – (1/2 × 0.6m. )]
= [ 1m – 0.3 m ]
= side AB – side FB
= 2.2m – 0.7m
I have redrawn the triangle, with the calculated length of the sides AF & AE as shown below. Area of triangle AEF
