Design Your Own Vibrobots | Science Project

Use your design notebook to sketch out different ideas before you start building anything. Build a prototype, or initial version, of the design you think will work best. It is OK if your design does not work out exactly like you thought it would. You might realize as you start to build that there is a problem with your design.

What is vibro

Yet, a more detailed soils analysis may be required for vibro-compaction than for a deep foundation design because the vibro-compaction process utilizes the permeability and properties of the in-situ soil to the full depth of treatment to achieve the end result. A comprehensive understanding of the total soil profile is therefore necessary ...

Vibro stone column

Vibro stone columns or aggregate piers are an array of crushed stone pillars placed with a vibrating tool into the soil below a proposed structure. This method of ground improvement is also called vibro replacement.Such techniques increase the load bearing capacity and drainage of the soil while reducing settlement and liquefaction potential. Stone columns are made across the area to be ...


The design of vibro-replacement stone columns is traditionally carried out using a partly analytical, partly empirical method developed by Priebe (1995). The contractor's initial design was based on this method which applies an 'improvement

How soil properties dictate vibro stone column installation

Installing vibro stone columns —also known as aggregate piers— has fast become a preferred ground improvement method when soil can't hold up a foundation on its own. Read on to learn how ground improvement contractors analyze a site's soil properties to design treatments and determine installation methods.
