Embodiment 1

[0034] Embodiment 1: The present invention provides a kind of rock and soil mass in-situ strength bearing plate test device, its structure is as follows figure 1 , figure 2 shown. figure 1 The block diagram includes PC, tester, power mechanism, pressure unit, data acquisition and feedback unit; figure 2 The physical structure diagram includes part of the power mechanism, pressure-bearing unit, equipment components in the data acquisition and feedback unit, and auxiliary support structures. image 3 It is the structure diagram of the control panel at the front of the tester chassis.

[0035] The PC is interconnected with the tester, and the control module in the tester is a single-chip microcomputer system, which is used for programming control of the test mode and test process, data collection, storage and online communication with the PC.

[0036] The power mechanism includes a generator, a motor driver, a torque motor 16 , a speed reducer 15 , a shaft coupling 14 and a ...

Embodiment 2

[0040] Embodiment 2: Adopt the in-situ strength bearing plate test device of rock and soil mass in Example 1 of the present invention to carry out the in-situ strength bearing plate test of rock and soil mass, the structure when installing the test device is as follows figure 2 shown. The large crossbeam 1 rides on the test rock and soil mass 7 around the test pit 18, two self-locking winches 2 are installed on the large crossbeam 1, the small crossbeam 4 is suspended by the steel wire rope 6, and the length ratio of the steel wire rope 6 on both sides is adjusted. Different test angles can be obtained; the power and power transmission components of the device include a torque motor 16, a reducer 15, a coupling 14 and a screw jack 13, and the entire power and power transmission components are hung under the small beam 4 by the jack buckle 20 The pressure-bearing mechanism and the pressure sensor pass through the slide bar 3 and the slider 5, and are suspended on the lower rig...

Embodiment 3

[0049] Embodiment 3: adopt the in-situ strength bearing plate test device of rock and soil mass in Example 1 of the present invention to carry out the in-situ strength bearing plate test of rock and soil mass, the structure when installing the test device is as follows figure 2 shown. The difference is that in the operation method: step (4) the test device works offline without a PC. When working offline, pass image 3 The keyboard on the control panel sets the test parameters and test process. The main setting items include test mode, loading interval and data sampling frequency. The test mode includes three modes: load by force, load by displacement and load by time. Other test steps are the same as in Example 2.

Abstract

The invention relates to a testing device of a rock-soil body in-situ strength bearing plate and a usage method of the testing device. The testing device comprises a PC, a tester, a power mechanism, a bearing unit, a data collection and feedback unit and an assisted supporting structure; the PC and the tester are connected with each other, and a control module in the tester is a single chip microcomputer system; the power mechanism consists of a power generator, a motor driver, a moment motor, a speed reducer, a coupling and a jack; the bearing unit consists of a stress transmitting pillar and a bearing plate; the data collection and feedback unit is mainly provided with a rotary encoder and a pressure sensor. The device is assembled into a whole in a buckling manner, the rigid loading requirement needed by testing can be guaranteed; and in moving, the testing device can be conveniently moved and transported after being disassembled into small units. The usage method can be controlled by a program online or offline, the testing mode can be selected from a time mode, a displacement mode and a pressure bearing mode. The testing device and the usage method have the advantages that the mode switching is flexible, the testing process, data sampling and storage are automatic, and the like, and the testing efficiency and the quality reliability of testing data can be improved.

Description

technical field [0001] The present invention relates to an in-situ strength bearing plate test device for rock and soil mass and its use method, in particular to a pressure-bearing plate test device and its use method related to the in-situ strength test of rock and soil mass, which is a test mode The invention discloses an automatic pressure-bearing plate test device and a use method which are adjustable, disassembled and moved conveniently, and belong to the field of in-situ test of geological engineering rock and soil. Background technique [0002] With the increase of engineering construction and the continuous increase of construction scale, various geological disasters such as landslides, debris flows, subsidence, etc. have become more and more frequent, and the stability of rock and soil has been increasingly recognized by scholars and engineers at home and abroad. focus on. The stability of rock and soil depends on its own mechanical properties, so the relationship ...
