Abstract

The invention discloses a ground fissure geological hazard measurement device, which comprises an ultrasonic detection unit, the ultrasonic detection unit includes an ultrasonic transceiver probe; the deformation amount detection unit includes a satellite positioning measurement antenna; the image acquisition unit includes a camera; On both sides of the ground fissure, and positioning piles are movably arranged on the slide rail mechanism; the first positioning mechanism includes a first telescopic cylinder arranged on the positioning piles, and a second telescopic cylinder is vertically provided at the output end of the first telescopic cylinder, The output end of the second telescopic cylinder is fixed with an ultrasonic transceiver probe; the second positioning mechanism includes a cylinder arranged at the top of the ground fissure, and the cylinder is provided with a third telescopic cylinder and a fourth telescopic cylinder, and the third telescopic cylinder and the fourth The output end of the telescopic cylinder is set in reverse; the present invention can overcome the influence of environmental factors and the internal structure of ground fissures on the detection results as a whole, improve the measurement means of ground fissures, and provide key parameters and important characterizations for accurately judging the stability of excavation projects.

Description

technical field

[0001] The invention relates to the technical field of ground fissure engineering measuring devices, in particular to a ground fissure geological disaster measuring device. Background technique

[0002] Ground fissures are mainly fissures or faults that occur in the soil layer. Ground fissures are often combined in multi-level echelon on the surface, and some can be connected into huge cracks. With a large number of engineering construction activities (such as underground ore body excavation, slope excavation, foundation pit excavation, groundwater exploitation, etc.), ground fissures are more and more common. Undoubtedly, the construction of these projects will inevitably lead to a certain scale of cracking on the surface around the excavation, and even cause geological disasters such as surface subsidence and landslides, which will bring serious damage to project construction activities and the safety of people's lives and properties. threatened to cause h...

Embodiment 1

[0040] This embodiment is a detection technique aimed at the phenomenon of ground fissures 2 widely existing in northern cities at present. Ground fissures 2 is a geological phenomenon, that is, under the action of natural or human factors, the soil layer on the ground surface or Cracks occur in rock formations, and cracks of a certain length and width are formed on the surface. When this phenomenon occurs in areas with human activities (mainly towns and villages), it becomes a geological disaster. It can directly destroy various engineering buildings and cause a series of environmental problems, which will have a great impact on people's personal safety, property safety and normal production and life. Therefore, in order to reduce the threat and damage of the ground fissure 2 to the people, it is necessary to strengthen the monitoring and prevention of the ground fissure 2. When monitoring, it is generally necessary to pay attention to the monitoring point, and the key measure...
