Abstract

The invention discloses a composite electrode device for direct-current electrical prospecting and an operation method of the composite electrode device. The device comprises a conical spiral telescopic electrode and a disc-type base, wherein the disc-type base comprises a protection casing, a water storage cavity is formed in the protection casing, and the bottom end of the water storage cavity is communicated with a high-compression sponge through a water seepage plate; a water injection hole is formed in the protection casing and is communicated with the water storage cavity; the electrode penetrates through the water storage cavity and the high-compression sponge of the disc-type base to reach the bottom of the disc-type base. The composite electrode device has the benefits that the device adopts a center fixing structure comprising the disc-type base and the electrode and can be used for both a hard ground surface and a soft ground surface. The whole device can naturally and fixedly stand on the ground, the central electrode and the ground are sufficiently coupled due to the design of the water storage cavity and the high-compression sponge, and with the adoption of the design of a slot and elastic fixing contact pieces, connection of the electrode for direct-current electrical prospecting and a main unit is facilitated.

Description

technical field [0001] The invention belongs to the technical field of geophysical exploration or detection, and in particular relates to a direct current method exploration composite electrode device and an operation method thereof. Background technique [0002] The direct current method refers to a type of geophysical exploration method that can realize resource exploration and solve some engineering geological problems by studying the distribution characteristics and laws of the direct current electric field related to geological bodies. It includes high-density resistivity method, ordinary resistivity method and excited polarization method, etc. The working method of the direct current method is mainly to use the contact between the electrode and the ground to excite and observe the direct current electric field. [0003] The simplest electrode can be a copper or iron rod. This simple electrode can be easily inserted into the soft surface soil for fixing and coupling, b...
