Abstract

The invention belongs to the technical field of civil engineering, and particularly relates to a flexible displacement measuring device and measuring equipment. The measuring device comprises fixing blocks, the two fixing blocks are oppositely and fixedly arranged in a drilled hole formed in a rock, a data collector is arranged in the middle of each fixing block, and the two data collectors are connected through a wire; the two ends of a sealing sleeve are connected with the two fixing blocks in a sealed mode respectively, and the wire is arranged in the sealing sleeve. The device can adapt to the shear deformation of rock mass, prevents the wire from being broken or snapped, and has a very good practical value.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and in particular relates to a flexible displacement measuring device and measuring equipment. Background technique [0002] Rock mass is a complex structure affected by many discontinuities such as joints, fissures, weak interlayers, and fractures. The mechanical characteristics and engineering geological characteristics of discontinuities are crucial to the judgment of engineering stability. The failure mode and deformation characteristics of the rock mass at different radial depths of the surrounding rocks show different changes. Therefore, the deformation monitoring inside the rock mass is very important for the study of the deformation law of the rock mass and the design of the deformation control of the rock mass. [0003] The Chinese patent with the application number "201810453297.5" and the patent name "rock deformation measurement device and rock measurement equipment" disclos...
