Description

Measuring device for hydraulic ring geological fracture Technical Field The invention relates to the technical field of hydraulic ring geology, in particular to a measuring device for hydraulic ring geological cracks. Background The investigation and monitoring of hydraulic engineering ring geology (hydrogeology, engineering geology and environmental geology) is a basic work for guaranteeing national major engineering construction safety, evaluating geological disaster risk and carrying out ecological environment protection. Among them, cracks (including fissures, joints, faults, etc.) in rock mass, soil mass or concrete structures are the core observation objects. The geometric parameters (such as strike, dip, width, length, density) of the fracture and its dynamic changes (such as expansion, contraction, dislocation) are directly related to the stability of the rock mass, the seepage characteristics and the long-term safety of the project. Currently, the measurement of geological cracks of hydraulic rings mainly adopts the measurement of a feeler gauge, the non-contact photogrammetry and the measurement of an embedded sensor. When the feeler gauge is adopted for measurement, the measurement process is highly dependent on manual operation, the efficiency is low, the influence of the technical level and subjective judgment of measurement staff is great, and the data consistency is poor. For cracks with dangerous positions (such as high slopes, deep foundation pits and the tops of caverns) or small/huge dimensions, the measurement difficulty is high, the risk is high and the precision is difficult to guarantee. When non-contact photographic measurement is adopted, the measurement accuracy of the common digital photography is obviously affected by camera calibration, lens distortion, shooting angle and illumination condition, the data processing is complex, the quantitative result is difficult to obtain in real time, and the measurement is not very convenient for depth cracks. When the embedded sensor is used for measurement, only the change data of single points or limited points of the mounting position of the sensor can be obtained, and the overall shape and the expansion condition of the crack cannot be comprehensively represented. The installation process often needs drilling and burying, can cause local disturbance or damage to the rock and soil body, is difficult to adjust the position after laying, and has insufficient flexibility.
