how to separate metal ball bearings,sand and gravel ...

Jan 14, 2007· Since sand is rectangular in shape and the bearings are round, tilting the mixture would cause the bearings to reach the bottom first. (Be sure to spread the sand/bearing combination fairly thin on a large cookie sheet.) 4) Assuming this is a dry mixture, the sand/metal combination could also be separated by "pouring" it into a stiff wind.

Also, soil from the embankment may fall into the trench. That loose soil has much less bearing capacity than the original soil. That's why it is so important to compact the trench bottom (use a vibrating plate compactor for sand or gravel soils, and a jumping jack compactor for silt or clay).

Bearing capacity Wikipedia

In geotechnical engineering, bearing capacity is the capacity of soil to support the loads applied to the ground. The bearing capacity of soil is the maximum average contact pressure between the foundation and the soil which should not produce shear failure in the soil.

What is Bearing Capacity of Soil? How to improve it?

Note: This method is most effective for sandy and gravel type soil not for clay type. By Compacting: Compaction reduces the open space between the individual particles of soil and hence they are less liable to displacement, thereby it will indirectly increase soil bearing capacities.

HOW TO IMPROVE BEARING CAPACITY OF SOIL?

If we compact soil using appropriate method, then there will be increase in its density and shear strength. As a result the bearing capacity of soil also increases. There are many methods of compacting soils on site. Few of them are mentioned below. By spreading broken stones, gravel or sand and thereafter ramming well in the bed of trenches.
