Intensity distribution test device for deep-hole drilling rock and earth mass

Abstract

The invention discloses an intensity distribution test device for a deep-hole drilling rock and earth mass. The intensity distribution test device comprises a power supply, a drilling system and a data acquisition system, wherein the drilling system comprises a convex-tooth conical drill bit, a spiral drill rod, a rotating ring, a drill, a hole-drilling rack and an operating handle; the convex-tooth conical drill bit is connected with the spiral drill rod in a fastening manner; the spiral drill rod is in threaded connection with the drill; the drill is fixedly arranged on the hole-drilling rack and is connected with the power supply; the data acquisition system comprises a pushing-twisting sensor, a rotating speed sensor, a current meter and a laser ranger which are connected with the power supply; and all the devices respectively output thrust and torsion, the rotating speed of the drill rod, current and drill rod footage signal data to a data acquirer connected with a micro computer. The intensity distribution test device is simple and is convenient for construction, can obtain the intensity distribution of the rock and earth mass while drilling and can supply intuitive and detail data.

Description

technical field [0001] The invention relates to the technical field of strength testing of geotechnical engineering, in particular to a device for testing the strength distribution of deep hole drilling rock and soil mass. Background technique [0002] At present, the traditional rock and soil strength testing devices and methods are mainly obtained by sampling in the field, reshaping samples indoors, and loading tests on material testing machines. There are two problems with this type of device: first, it is difficult to reproduce the stress environment of rock and soil and the spatial distribution of soil and rock after reshaping the sample, and the strength parameter data obtained from the test have great dispersion; second, it is difficult to meet the requirements of various Due to the need for "rapid disposal" of emergency rescue for similar engineering construction and major engineering disasters, it is unable to provide first-hand supporting data for scientific decisi...

Problems solved by technology

[0004] The purpose of the present invention is to propose a deep hole drilling rock and soil strength distribution testing device, which solves the problem that the traditional testing device cannot obtain the strength properties of the rock and soil with the test of the borehole, and then draws the columnar shape of the strength of the rock and soil in the borehole as it changes with depth. and analyze the mechanical properties of rock and soil in time to quickly make safe construction decisions
