Definitions

  • the present invention relates to a novel analysis apparatus used through a drilling well and a novel surveying method to be used together with said apparatus, which are developed in order to be able to analyze the ground surface layers in any region in detail.
  • Standard penetration test provides information about the hardness of the surface as a result of 0 to 50 strikes. Aforementioned experiment can be performed at 1.5 meters. It cannot be applied to the ground surfaces of stiff blocks. Results of the measurements may vary across the operators performing the test by a mechanical test system. The data obtained as the result of said standard penetration test are not assumed to be continuous soil survey data . Thus the aforementioned standard penetration test is not a strong test method in adequately showing the ground surface characteristics in detail. This makes the scope of application of the standard penetration test limited.
  • CPT cone penetration test
  • the fundamental principle of the cone penetration test is based on determining the surface parameters via the end resistance, lateral resistance and the pore water pressure obtained by drilling a tapered cylinder (with a conical tip) into the ground. Hence the structural properties of the soil can be obtained via the measured resistant and frictional values.
  • Cone penetration test allows obtaining test results with higher continuity as compared to the standard penetration test . Nevertheless the cone penetration test is suitable to be applied on soft ground surfaces in general . It is not possible for this test to be applied on hard and rock soils since the test performed by drilling of the measuring device of a cylindrical tube form and of a conical head in through the soil is accompanied by high forces.
  • Vane test is performed in the laboratories or on the land in order to measure the shear stress of the clay soils, without drainage.
  • the probe structure used in the experiment is composed of perpendicularly joined 4 metal plates. In order to perform the experiment first of all the probe is drilled into ground surface. The surface is cut afterwards by applying a torque to the probe. The value of the torque applied and the resistance of the ground surface against these forces are measured in the course the process. The characteristics of the soil are thereby obtained.

  • test methods in the art are not suitable to be used on all types of ground surfaces. Especially, scarcely are there test methods to be applied on hard ground surfaces . Data obtained from the test methods which are applicable with hard surfaces, on the other hand, are quite inadequate . Thus there doesn't exist a test method in the art which is capable of both being able to be applied on any type of ground surface and delivering detailed and continuous test results for the soil structure.
  • An object of the invention is to provide a novel analysis apparatus designed to be used in soil survey.
  • Another object of the invention is to provide a novel soil survey test involving continuity by virtue of said novel analysis apparatus .
