CONE PENETROMETER INSTALLED ELECTRICAL CONE PROBE AND THE SUBSURFACE INVESTIGATION METHOD

摘要

the invention of the tip cone penetrometer to measure electromagnetic waves by a very accurate estimate of soil spatial distribution characteristics through the void ratio can be calculated, from which provides the apmildo Additionally equipped with a cone to cone probe is to be calculated using the same testing and test methods for geotechnical investigation has its purpose. ; above cone cone probe tester is equipped according to the present invention for achieving the object is to the distal end portion of the penetration rod, and the cone penetration as probes to measure the electrical resistance near the distal end; As the probe fixed to the cone with the electromagnetic wave of the electromagnetic wave generating device for generating a high frequency; And a junction connecting the cone probe and an electromagnetic wave generator; And a measuring device that measures an electromagnetic wave generated by the electromagnetic wave generator; Wherein the measured electromagnetic signal characterized by consisting of a transport device to change a digital signal transferred to the computer. ; In addition, the probe is equipped with conical cone testing machine according to the present invention for achieving the above object site investigation test is installed to a certain length at the ends to intrusive to the depth required by the threaded distal end of the probe to the cone penetration rod, install the electromagnetic wave generating device and measurement device using a probe in proximity to the cone, and installing the transfer unit for transferring the electromagnetic wave to the inside of the penetration rod, comprising: a cone assembly tester connected to a computer cone probe is mounted to the transfer unit; Measuring the electrical resistance and penetration Sikkim electromagnetic waves in the cone penetration probe rod on the shore and at the same time the ground; After measuring the penetration depth of the electrical resistance is characterized by made of a step of evaluating the void ratio by calculating the depth specific electrical resistance.
