Movable variable-pitch underground space structure detection equipment and method

Abstract

The invention discloses movable variable-pitch underground space structure detection equipment and method, and the equipment comprises a discharge vehicle and a measurement vehicle which are the same in structure, and each of the discharge vehicle and the measurement vehicle comprises a vehicle body, an electrode moving guide rail, an electrode, an electrode dotting controller, an adjusting switch, a discharge power supply and a measurement ammeter; a driving mechanism and an onboard computer are carried on the vehicle body, the electrode moving guide rail is arranged on the vehicle body, the electrodes are installed on the electrode moving guide rail through the electrode dotting controller, the electrode dotting controller is used for controlling the electrodes to make contact with or be separated from the ground, and the distance between the electrodes can be adjusted. The measuring electricity meter is connected with the airborne computer; the regulating switch is used for controlling the electrode to connect a discharge power supply or a measuring ammeter; the airborne computer is used for collecting and updating test data in real time and uploading the latest test data to the cloud, and processing the test data in real time to obtain a test result. According to the invention, the limitation of a traditional resistivity test cable is broken through, the electrode distance is controllable, the flexibility is high, and the application prospect is good.

Description

technical field [0001] The invention relates to the technical field of underground space structure detection, in particular to a movable variable-distance underground space structure detection equipment and method. Background technique [0002] Direct current prospecting is an important technology in the field of geophysical prospecting. It is based on the difference in resistivity in the detection area, and determines the distribution characteristics of the underground structure in the detection area by arranging artificial electric fields in the detection area and testing the distribution of the electric field in this area. The direct current method has developed rapidly. From the original four-pole arrangement method to today's high-density direct current method, relatively rapid testing has been achieved, and the test accuracy has also been improved accordingly. [0003] At present, the high-density electrical method mainly adopts the method of arranging electrodes with...
