Problems solved by technology

During the measurement process, a 3D laser scanner is artificially set up, and the instrument is recovered to obtain data after the measurement is completed. The measurement cycle and data frequency are completely dependent on manpower, and it is impossible to achieve fixed cycle, high-frequency measurement and automation of data collection, and it is impossible to measure deep displacement of rock mass
[0006] The convergence meter can only measure the surface deformation of the surrounding rock of the tunnel, and cannot obtain the deep deformation of the rock mass, and is greatly disturbed by engineering construction

Abstract

The invention discloses a rock deformation measuring device and rock measuring equipment and belongs to the rock measurement technical field. The rock deformation measuring device comprises an anchoring head, a pulling rope, a plurality of measuring components and a plurality of connecting components; the anchoring head is connected with an end portion of the pulling rope; the pulling rope passesthrough the plurality of measuring components sequentially; the measuring components can retract the pulling rope, so that the length of the pulling rope between two adjacent measuring components canbe decreased, or the measuring components can release the pulling rope, so that the length of the pulling rope between two adjacent measuring components can be increased; two adjacent measuring components are respectively connected with two ends of the corresponding connecting component; one connecting component is connected between the anchoring head and the adjacent measuring component; and theconnecting component can be selectively elongated and shortened. The rock measuring equipment is provided with the above rock deformation measuring device. With the rock deformation measuring device and rock measuring equipment of the invention adopted, deformation measurement of different points in the deep part of rock mass can be realized, and a surrounding rock radial deformation measurement task can be completed.

Description

technical field [0001] The invention relates to the technical field of rock measurement, in particular to a rock deformation measurement device and rock measurement equipment. Background technique [0002] The radial displacement of the surrounding rock in underground engineering is the most direct parameter corresponding to the excavation mechanics of the surrounding rock, and the radial displacement has always been the main basis for the prediction, evaluation and control of the stability of the surrounding rock. The distribution of the stress field of the rock mass is different at different radial depths of the surrounding rock, and the failure mode and deformation characteristics change with the depth. Therefore, the measurement of the radial deep deformation inside the rock mass is very important for the study of the deformation law of the rock mass and the design of the rock mass deformation control. [0003] In the existing measurement implementation methods, multi-p...
