Technical Field

The invention relates to the technical field of geological measurement, in particular to a measuring device and a detecting method for a hydraulic ring geological crack.

Background

Earth fractures are a progressive disaster with progressive development. The formation can be divided into two categories according to the cause, one is a structural ground crack formed by internal power, such as an earthquake crack, a base fracture movable ground crack, a hidden crack opening crack and the like; the other is non-tectonic type, namely the ground cracks formed by the action of external power, such as loose soil body subsurface corrosion ground cracks loess collapsible ground cracks, expansive soil expansion ground cracks, landslide ground cracks and the like. The extension of the tectonic ground fissure is stable, and the tectonic ground fissure is not influenced by the ground surface topography, the rock-soil property and other geological conditions, and can cut off linear landforms such as staggered ridges, steep ridges, river terraces and the like. The activity of constructing the ground fracture has obvious inheritance and periodicity. The tectonic ground cracks are arranged on the plane in an intermittent broken line shape, a saw tooth shape or a wild goose row shape; the earth surface rock and earth mass are approximately vertical on the section and arranged in a ladder shape, a cutting shape and a base shape, the cracks are a geological phenomenon that earth surface rock and earth mass are cracked under the action of natural or artificial factors and form cracks with certain length and width on the ground, and when the cracks occur in areas with human activities, the phenomenon can become a geological disaster. The formation of ground fractures refers to the displacement or dislocation of rock strata caused by dislocation of underground faults during strong earthquakes, fractures are formed on the ground, the trend of the fractures is consistent with that of underground fracture zones, the scale is large, and the fractures are distributed in a strip shape.

At present, the width of a ground crack can be measured by adopting a traditional graduated scale, but the depth of the ground crack is difficult to measure generally, the depth of the ground crack is often inconsistent, and several points are selected for measurement in a frequently-adopted mode.
