Abstract
This invention provides an understanding of the structure and porosity of soil and stony regions. The method is characterized by release of a measuring gas in the region being investigated and its penetration through the investigated region to several places where it is captured and measured. Thus, the measured data from the various measuring locations provides the structure and the porosity of the region being investigated. The method is especially suited for the investigation of dams and the location of underground cavities and tectonic faults.
Claims6
The non-destructive method of investigating the structure, dampness, and porosity of soil and stony bodies over substantially large areas such as that effecting the percolation of water in areas about dams, comprising the steps of,
- introducing a measuring gas under slight pressurization at an injection site in the locality being investigated to penetrate the soil and flow outwardly from the injection site as a function of the porosity and dampness of the soil,
- recapturing and measuring the gas at several measuring sites remote from the injection site after penetration into said bodies, and
- measuring the time of penetration through the bodies under investigation from the injection site to the measuring site and the concentration of the resulting gas to establish the dampness and porosity of the bodies.
