Device and method for detecting tensile strength of rock-soil body

Abstract

The invention discloses a device and method for detecting the tensile strength of a rock-soil body, and belongs to the field of rock-soil detection. The device comprises a detection box, a vertical block is fixedly installed at the top end of the detection box, a movable plate is connected to the top of the vertical block, and a top plate is installed at the top end of the movable plate. By arranging a uniform stretching mechanism and electrifying a first servo motor, a first rotating rod drives a first gear to rotate, so that the first gear drives a two-way gear to rotate, four groups of second gears are arranged on the inner wall of the two-way gear, so that the second gears rotate, and through meshing connection of the second gears and a gear rack, the second gears drive the gear rack to stretch, further the gear rack slides in a fixing plate through the sliding plate and the sliding groove, the first bottom plate and the second bottom plate drive the rock soil to carry out tensile detection, and through the arrangement, the rock soil can be uniformly detected in multiple directions.

Description

technical field [0001] The invention relates to the field of rock and soil detection, and more specifically, relates to a tensile detection device and a detection method for rock and soil bodies. Background technique [0002] Geotechnical engineering is a branch of civil engineering. It is a science that uses engineering geology, soil mechanics, and rock mechanics to solve engineering technical problems related to rock and soil in various projects. According to the division of engineering construction stages, the work content can be divided into: geotechnical engineering survey, geotechnical engineering design, geotechnical engineering treatment, geotechnical engineering monitoring, geotechnical engineering testing. [0003] Existing tensile testing devices for rock and soil usually do not have a mechanism for multi-directional uniform tensile testing of rock and soil, and do not have a mechanism for vertically stable tensile testing of rock and soil, and do not It has a me...

Problems solved by technology

[0005] In view of the problems existing in the prior art, the object of the present invention is to provide a tensile testing device and a testing method for rock and soil mass, which solves the problem that the existing tensile testing device for rock and soil usually does not have There is no mechanism for multi-directional uniform tensile testing of rock and soil, and there is no mechanism for vertically stable tensile testing of rock and soil, and there is no mechanism for cushioning and shock absorption for rock and soil during testing, and there is no mechanism for different The mechanism for stable detection of rock and soil of different types leads to poor tensile detection effect of rock and soil, low work efficiency, inconvenient use, and poor safety.
