Abstract

The invention discloses a focusing coupling electrode for hardened site detection, which comprises a lead, a top cover, a copper cake, a shell with an upper opening and a lower opening, clay, a bottomseal and a coupling bag, the top cover is screwed to the upper portion of the shell through threads, the bottom seal seals the bottom of the shell, and the lead penetrates through the top cover to bewelded to the copper cake, so that the copper cake is suspended and fixed to the inner side of the top cover; the shell and the top cover are filled with clay, and the coupling bag filled with the clay is sleeved at the bottom of the shell bottom seal. The outer contours of the top cover and the shell are rotating curved surfaces taking a parabola as a generatrix and a parabola symmetry axis as arotating shaft, the top cover and the shell are made of organic glass, the copper cake is fixed at the focus position of the parabola, and the geometric center of the copper cake coincides with the focus of the parabola. According to the invention, the shell is designed to be a rotating curved surface taking the parabola as a reference, and the copper cake electrode is fixed at a focus position,thereby achieving the focusing power supply of a current, and improving the detection resolution. The electrode does not need to be driven underground and is directly placed at a corresponding position, thereby greatly improving the working efficiency.

Description

technical field [0001] The invention relates to a coupling electrode, in particular to a focusing coupling electrode used in the detection of hardened sites, which can be widely used in the electrical detection of hardened sites (such as municipal roads, airports, squares, dams, etc.) for detecting Distribution of media and structures under hardened sites. Background technique [0002] Electrical detection is a kind of geophysical method based on the difference in electrical properties between media, through observing and analyzing the distribution characteristics of these electrical differences in space to infer underground geological structures and find underground electrical inhomogeneities. It is one of the most effective means of engineering geological exploration. However, in the detection of hardened sites such as municipal roads, airports, and dams, electrical detection is often difficult to carry out due to reasons such as difficulty in arranging electrodes and exc...
