Calibration cable for geological exploration

Abstract

The invention discloses a calibration cable for geological exploration. A plurality of conductors and a tensile element are mixed to from a cable core. The cable core is wrapped by a sheath layer in an extruding manner, and the sheath layer is provided with calibration rings at equal intervals of L. The external diameter of the sheath layer is set as D, and the internal diameter of each calibration ring is set as d. The surface of the calibration ring is provided with a red mark or a mark with another color, and is made of rubber. The cable is manufactured according to a technological operation flow, and one calibration cable segment is selected from the finished cable for detection. The cable irons out the defects that there is no calibration interval in conventional cable detection, the conventional cable detection is not suitable for deeper geological conditions and cannot precisely complete a geological exploration task, the service life of the cable is affected when the length of the cable needs to be designed and calculated for the detection of the geological conditions at one depth and the detection cost is increased. The cable is especially suitable for the detection of the geological conditions of places with the frequent natural disasters, such as earthquake, mud-rock flow and landslide.

Description

technical field [0001] The invention relates to a calibration cable for geological exploration. Background technique [0002] Existing cables used by instruments and equipment for geological condition detection in places where earthquakes, mudslides, landslides and other natural disasters occur frequently are special special cables. The all-weather geological environment must have the characteristics of cold resistance, sunlight resistance, humidity resistance, high temperature resistance, etc. Especially for the detection of geological conditions up to 100 meters below the surface, in addition to the cable should have sufficient tensile strength, it should also be There are superior technical measures to ensure that the cable is not affected by sediment, sandstone, magma, water pressure, etc. on the detection process without affecting the accuracy of the measurement; especially when detecting a certain deep geological condition, it is necessary to The length of the cable i...

High-frequency use requirements do not match, which affects the service life of the cable and increases the cost of detection
