[0002] In geophysical exploration projects, a large number of electrodes are used in electrical testing, ranging from dozens to hundreds. During the test, most of the electrodes need to be driven into the soil, and after the test, the electrodes need to be pulled out of the soil. The requirement for the electrodes is to ensure good grounding. Usually, the electrode material is brass, which has good conductivity. Current electrodes have the following defects:

[0003] 1. The head of the electrode is fragile after being struck repeatedly. Even if there is a screw protective cover on the head, it is easy to break, resulting in a smaller striking surface.

[0004] 2. In some special soil layers, it is difficult to pull out the electrode after it is inserted;

[0005] 3. The tail of the electrode is conical, which is easy to bend when encountering hard strata or rock bedrock, making the electrode unusable;

[0006] 4. The electrode wire is fixed to the surface of the electrode by screws, which may cause wire breakage.

[0007] Based on this, the present application provides a new type of electrode for geophysical exploration, which has a hammer-resistant head, an electrode wire that is not prone to breakage, and a long service life. Utility Model Content
