Embodiment Construction

[0040] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings, but they do not constitute a limitation to the present invention, and are only examples. At the same time, the present invention will be further described in detail through and specific implementation.

[0041] Such as Figure 1~3As shown, the present invention has designed a kind of device that automatically tests surrounding rock loose circle in dry hole, and it mainly comprises the external water injection capsule 4 and the hole detection robot 8 of the bottom.

[0042] The water injection capsule 4 is a frame structure, and is outsourced at the rear of the drilling robot 8 . The robot driving device 14 of the drilling robot 8 can drive the whole device to move in the drilling to ensure multi-point automatic testing in the drilling.

[0043] The water injection capsule 4 includes at least one top water storage bladder 4.1, at least one middle...

Abstract

The invention discloses a device and method for automatically testing the loose circle of surrounding rock in a dry hole. The device comprises a water injection capsule on the outside, a manhole robot at the bottom and a robot walking driving device. The water injection capsule comprises a plurality of water storage bags, and the adjacent water storage bags are communicated and connected through water-filled pipelines. The water storage bag at one end is provided with a water injection pipe and a tail exhaust pipe, and the water storage bag at the other end is provided with an end exhaust pipe. At least one acoustic wave emitting probe and at least one acoustic wave receiving probe are arranged in the water storage bags, and the acoustic wave emitting/receiving probes are connected with a loose circle tester through connecting wires. The manhole robot and the robot walking driving device are connected with a robot control device. The device is wide in application range, extremely small in water consumption, easy and convenient to use and capable of being applied to testing of dry holes and holes with water and is a rock and soil acoustic wave testing coupled system device which is wider in application range, more convenient to operate and more accurate in testing result.

Description

technical field [0001] The present invention relates to the technical field of testing loose circles of surrounding rocks inside rock mass, and specifically refers to a device for automatically testing loose circles of surrounding rocks in dry holes. The invention also relates to a method for testing loose circles of surrounding rocks using this device. . Background technique [0002] With the complexity of engineering construction and the improvement of engineering geological requirements, we often need to test the structural conditions and mechanical properties of the rock and soil of the engineering site in order to evaluate and make decisions on the design and construction of major geotechnical engineering and its impact on the environment. [0003] At present, the quantitative research of geotechnical engineering is carried out by means of acoustic wave testing. Specifically, the electromagnetic excitation method is used to emit sound waves to the medium (such as: rock,...
