Dear Sefians,

Can someone give me some details of vibration isolation pad...how it
is laid...and how to cast a Vibratory foundation over it..if I dont
want to transfer the load to the fondation just below the vibratory
foundation....some details on how to decide thickness of pad to be
adopted....I have browse the forum ..i dont not got something
satisfactory...

Regards,
S.Adhikari

Your isolation system will depend on the frequency of the equipment. You can at best hope for 80 % isolation and no more with a single system of isolation. An "anti-vibration pad" may not be the ideal solution. It could be that spring isolators may be better. You should contact a vibration isolator manufacturer to get a solution--but ensure they provide calculations to prove their claim. Usually for small orders they may not oblige--that's where your power of persuasion will be put to test! A poorly designed isolation system is a waste of money.

Dear Sukanta,

I can send you the procedure of casting the concrete block over our spring units, if you can give me your email id. For more information you may log on to our websitewww.baseisolators.com

隔离ation pads are not a good solution. We can give you low natural freq. long lasting solutions out of springs that can be very easily tested and calibrated.

On laid raft, upper vibratory massive concrete block has to be laid.

Neoprene pads mounted on steel plates should be designed & procured from specialist manufacturer.

These pads are small sqare in plan with considerable resistance of Neoprene 20 or 25mm thick. Hardly, these would require 10 to 15 % area of the RCC raft.

Specialist manufacturer would assist the procurer about the design capacity of the Neoprene pads. These pads are for sure very resistive to the sustainable forces & may not be required to be fixed on the whole surface.

These steel plates are to be connected to the raft using steel manufactured concrete nails.

These pads after being installed, require surrounding RCC surface to be covered with polystyrene material.

All these mountings & polystyrene materials are to be covered with flexible polystyrene covered with rubber sheet over.

A steel lamina or plate has to be fabricated using angle sections so that plate can be lifted & placed on the isolation system. Plate shall be fabricated by welding.

The Design Rebars are to be placed.

The formworks are to be prepared.

All angles of the lamina must be embedded into the concrete. Plane side of the lamina should face other side of concrete isolation touching rubber sheet.

Grooves need be left as block outs for grouting purpose.

The foregoing system is meant for the horizontal body while, vertical sides require another vertical isolation system in a similar fashion but without steel lamina.

Corners require additional system too.

I have done such work in 1984 in SPLAJ Libya design procured from SACM France.

Dear Sukanta Sir,

I think isolation foundation is the best solution in present situation.
the detailed procedure and images kindly visit to our websitewww.antivibrations.com

亲爱的先生,
To counter vibrations from a machine, rubber is probably best material.
Rubber Pads, Sheets, Mounts are readily avaialbe in market.
You can find some at:https://rubbersheetindia.co.in/neoprene-rubber-sheet
