A Deep Foundation definition is "A foundation that is placed at a greater depth or transfers the loads to deep strata "

• TRUE

• FALSE

Match the following

• end of the pile needs to be penetrated into the firm strata by at least three times the diameter

• REPLACEMENT PILES

• A hole is formed in the ground by removal of material from the ground, concrete is formed in it

• END BEARING PILES

• Piles is driven, pushed, vibrated, or screwed into the ground, but no material is removed

• DISPLACEMENT PILES

• sections of sheet materials with interlocking edges that are driven in the ground

• SHEET PILES

Propose the most suitable type of pile to construct a coastal protection works

• SHEET PILES – Steel Sheet Piles

• SHEET PILES - Precast Concrete Sheet Pile

• Raking piles

• Bored Pile

A wall made from properly this type of piles leaks very little.

They are commonly used in coastal defence works which are likely to be subjected to tidal action.

• SHEET PILES - Precast Concrete Sheet Pile

• BORED PILES

• END BEARING PILES

 Open Cut Method is not suitable for URBAN Areas because of the site constraints and the need to restrict ground movements adjacent to the excavation.
