minimum distance from Pile driving to Concrete structure casting 1

[Pupil2011]

Can anyone help me to determine the minimum distance from the pile driving area to concrete slab casting area. is there any standard mentioned this allowable distance?

Thank in adavance

Auger and micropile machines use to require 15 to 20 cm or more beyond perforated diameter to anything built, but it is better to check with the builder on its system.

Depends on many factors, including pile type, hammer type, soil conditions, etc.

Ishvaaag & Ron, Thank you for the Prompt response.

Pile type= RC precast
Hammer type=Brminig Hammer B-4505 (Ram Weight= 2993 Kgs)
Soil Type= medium dense to hard

area 2750 SqM, approximetly 700 Piles required to drive. we are planning to drive partially and start foundation slab concrete casting. but our client is not accepting this, hence im looking for the standard/code which has stated the acceptable distance for concrete casting during the pile driving.

Is there any objective evidence.

Thanks in advance.

This is the closer I have found for now.

I am still looking for more closer advice. The issue was I think to remember also addressed in another thread at this forum.

This article puts the displacement for hard soils at 25 m from the shaker at near 0.5 mm, enough to damage the adherence of deformed rebar in half-set concrete. If such was the case with pile driving, the concern of the client would be warranted.
