What is the minimum length of pile?

What is the minimum and maximum depth of a pile foundation generally used in building construction? – Quora. Generally for building constructions, it would vary from 3.5m to 20m. Minimum depth of foundation as per IS 1080-1982 is 50cm from Ground Level.

What is the maximum diameter of precast concrete piles that Cannot be exceeded?

Precast, prestressed concrete cylinder piles, up to 140 cm in diameter are also common in coastal areas and are driven as primarily as friction piles. Concrete piles provide high durability in marine environments and can provide high capacity.

What is the maximum length of a timber pile that can be taken before it fails by buckling?

Maximum length practically unlimited, optimum length: 12-50m.

What is the slump of piling concrete?

Detailed Solution

Placing condition	Degree of workability	Slump (mm)
Heavily reinforced sections in slabs, beams, walls, columns; Slipform work; Pumped concrete	Medium	50-100 75-100
Trench fill; In-situ piling	High	100-150
Tremie concrete	Very high	–

Which type of pile will last a limited number of years if it is not treated to ward off decay?

Timber piles will last only a limited number of years if it is not treated to ward off decay. Untreated timber piles can have a very long service life.

How long can timber piles be?

Timber piles have successfully supported structures for more than 6,000 years. Over the years, the methods that man has employed to extend the life of timber piling have evolved to the point that timber piles will last for over 100 years.

What type of pile is least prone to damage during handling?

Prestressed Piles: Prestressed piles are produced in the same manner as a prestressed concrete beam. The advantage of prestressed piles is their ability to handle large loads while maintaining a relatively small cross section. Also, a prestressed pile is less likely to develop tension cracks during handling.

What is the minimum depth of footings?

12 inches
Depth of Footings Footings should extend to a minimum depth of 12 inches below previously undisturbed soil. Footings also must extend at least 12 inches below the frost line (the depth to which the ground freezes in winter) or must be frost-protected.

What is pile depth?

A foundation is described as ‘piled’ when its depth is more than three times its breadth. Pile foundations are principally used to transfer loads through weak, compressible strata or water onto stronger, more compact, less compressible and stiffer soil or rock at depth.

What is the quality of concrete recommended for the precast reinforced concrete piles?

The grade of concrete to be used for piling should be minimum M25 (or as as required at the site for load conditions) with the minimum cement content of 400 kg/m3. Mixing is carried out in mechanical mixer only.
