How precast concrete piles could be assisted in penetration of soils

Solutions

Expert Solution

Answer:-

Increasing use of precast concrete piles was prevented for quite a long time by the lack of suitable, up-to-date equipment for driving the piles. Research work in the recent decade resulted in modern equipment for the complex mechanization of piling, largely widening the field of uses of precast piles. About twenty years ago the maximum depth to which precast piles could be used was considered still as 12 to 15 m, whereas today precast piles are driven to a depth of 50 m and more in practice, being manufactured in lengths of 5 to 8 m according to the production and driving technology.

Different kinds of pile driving equipment.

The latest development trend is to use vibrators and vibrating hammers for pile driving. Vibrated-in sheet piles haye heen used for quite a while, whereas for pile foundations, yibration is used only since recently.

According to the kind of dynamic effect, vihrators belong to two groups:

1.vibrators of a pure yibration effect.

2.Vibrating hammers combining vibration and blow by transmitting,
