Technical assistance: Is it possible to drive piles using hammers around the existing device?

This post was last edited by hesonchang214 on 2016-4-28 09:29. We have a chemical processing facility; the first phase was built previously, and now we are planning to construct the second phase. The second phase is adjacent to the first phase. There are three towers for which pilings need to be installed, and these locations are only about 10 meters away from the existing facility. The piles to be used are AB-type piles with a diameter of 400 mm and a depth of 17 meters. In order to save money, we would like to use hammer-driven pilings, but both the piling company and the design firm oppose this idea, suggesting that static pressure pilings or mixing piles should be used instead, as these methods will not cause any vibrations to the existing facility. Is it possible to use hammer-driven pilings in this case? Thank you!
The national regulations prohibit it; however, it is acceptable if the device next to you has not been manufactured.
It’s still in production. What specific regulation is it?
There should be guidelines; we’ve encountered similar situations before, which caused vibration interlocks in the compressor and led to an immediate shutdown~~~~
Take a look – there are details on the practical aspects of municipal engineering and building construction for the engineer certification exam; I’ve forgotten exactly where it is, but it contains the safety requirements for pile foundation work
Since both the pile foundation contractor and the design institute are opposed to it, their opinions should still be followed; you can also refer to the \"Technical Code for Building Pile Foundations\" JGJ94-2008
Hammer-driven piles are also an option, but appropriate measures must be taken to prevent the vibrations generated by hammering from affecting the operation of existing equipment; this can be achieved by installing isolation trenches or by shutting down the existing equipment to create a construction window.
