Pinhole Dispersion Apparatus

Description

Pinhole Dispersion Apparatus

Designed for the pinhole test, the pinhole dispersion apparatus identifies the dispersive characteristics of soil. It also, determines the stability of clay soils used. The test replicates the conditions of water flowing along a crack in a soil mass. The water flows through a 0.041 inch pinhole that is drilled into a compacted soil sample.

The dispersibility of the sample results from calculating the flow rate of water through the pinhole, evaluating the cloudiness of the water, and measuring the final size of the pinhole. The final test results reveal the cost-effectiveness of projects and identify potential safety issues.
