PROCEDURES

OBJECTIVE OF PROBE MACKINTOSH

1.Equipment for the test is assembled.The cone diameter is measured in SI unit.

2.Distance of 3.0m is measured and marked on the rod start from the tip of the cone.

3.The equipment is set up on the ground.

4.The hammer is pilled until it reached the maximum.The hammer is dropped freely to drive the cone into the soil.

a)Collecting a disturbed soil sample for grain-size analysis and soil classification.

b)Determine sub-surface straits graphed and identity materials present.

c)Evaluate soil density and in-situ stress condition.

d)Estimate geotechnical parameters.

ADVANTAGES OF PROBE MACHINTOSH

  • Light and easy user.
  • Does not need skill worker.
  • Economical.
  • Provides a disturbed soil sample for moisture content determination.
  • Faster and cheaper tools.

INTRODUCTION OF

SOIL INVESTIGATION

DEFINITION OF PROBE MACKIN TOSH

Soil Investigation is carried out for designing a right type of foundation safely and economically, a designer must possess sufficient information about the physical properties and the arrangement of underlying materials. The field and laboratory investigations required to get this essential information is known as soil exploration.

  • The soil investigation is the one thing that must be done before starting the construction of the building.
  • This is because the oil condition at the site need to be identifies to determine the suitable foundation use for the building and soil play a main role to support the load that come from the building and the building need a suitable foundation to transfer the load to the ground.
  • Therefore,the investigation of soil need to be done to identify the type of soil to ensure the soil can carry the load.

TRIAL PITTING

BOREHOLE

  • A borehole is used to determine the nature of the ground (usually below 6m depth) in a qualitative manner and then recover undisturbed samples for quantitative examination.

  • Trial pitting can be carried out by a variety of methods from hand dug pits to machine excavated trenches. Trial pitting is generally carried out to a maximum depth of 4.5m with standard excavation plant and, depending on soil conditions, is generally suitable for most low rise developments. All trial pit investigations are supervised by experienced engineers with a thorough understanding of geology and soil mechanics.

5.The sum of the number of below for penetration of 3.0m is recorded in the data sheet.

6.The hammer is taken off on the last 0.3 of each road and joined and existing rod with another rod and lastly the hammer.

The below is continued and stoppen when:

a)The below is more than 400 for 0.3m penetration.

b)The depth reached 15m.

IN-SITU TESTING

PROBE MACHINTOSH

  • In-situ testing techniques including Standard Penetration Testing, Permeability Testing, Borehole Vane Testing, Pressure meter Testing and Packer Testing can all be carried out in the boreholes in order to provide information for geotechnical design. Disturbed and undisturbed samples are retrieved from the boreholes for inspection and logging by engineers and subsequent testing in laboratories.
  • This is a dynamic penetrometer test used to check the consistency of the subsoil.

DISADVANTAGES OF PROBE MACHINTOSH

TYPE OF SOIL INVESTIGATION

Contribute to human error.

-wrong counting.

Low impact energy.

-only can penetrated in shallow soil (limited depth).

Unable to penetrated into madium strength soil and gravelly ground.
