Seismic Wave Generator

by John

To continue the posts about making the seismic wave generator.  See the previous post about water jet cutting the steel plates.

From what I am told, the generator is positioned, pinned to the ground, and hit on the ends with a sledge hammer.    Instruments pick up and measure the seismic waves in order to analyse what is beneath.

Sound is not required.  In fact sound is annoying and a disadvantage.

The operator stands on the generator while swinging the hammer.

So here is the finished item, ready to be delivered.  It weighs 20kg.

The seismic generator, ready to be delivered.  The brass plate is to remind the user to wear safety glasses, safety boots and ear protection.   The holes in the impact plates are to permit aluminium plates to be attached if the situation absolutely requires no sparks.

There are 10 ground pins.  Each pin is slightly tapered to make removal from asphalt or clay easier.   The pins are machined from 16mm set screws.  I imagine that 6 or 8 pins will be adequate to hold the generator in most surfaces.   The pins are removed for transport of course.

It will be interesting to hear how it performs.
