AI Technical Summary

Benefits of technology

This patented technology allows researchers to study rocks under different conditions without having to carry out complicated experiments or equipment that could affect their properties during testing. By doing this it simplifies the process while still providing accurate data about them.

Problems solved by technology

This patented technical solution describes how rocks have been developed over time by different companies but without any previous measurements from their fields or lab facilities. However, there may still exist issues with understanding these new measures due to challenges associated with current testing methods like destructive techniques which require samples taken away during exploration stages.

Embodiment Construction

[0033] The present invention will be described in further detail below through the accompanying drawings and embodiments.

[0034] The embodiment of the present invention provides an in-situ test method for obtaining rock parameters, such as Figure 1-5 As shown, it includes a test host, a pressure control system and a sensor measurement system. The test host includes a lower pedestal (1), a column (2), an upper top plate (3) and a locking nut (20), and the pressure chamber Placed on the lower seat groove (4) to increase stability, the pressure chamber is composed of a pressure chamber base (5) an acrylic glass cylinder (6) and a pressure chamber top plate (7). Connect the steel pedestal (8) and the pressure chamber base (5) with connecting bolts (9). During the test, place the core on the lower steel cylinder (10) and the lower steel cylinder (10). Install the axial pressure sensor (11) to measure the axial pressure. The axial pressure exerted by the hydraulic jack (13) is ...

Abstract

The invention provides an in-situ method for obtaining rock parameters, and relates to the field of rock inspection. The method comprises the steps of rock taking: two target drill cores with different diameter dimensions are drilled by using a small drilling machine; cutting: the drill cores are processed by using a cutting tool, the drill cores are put into a steel sleeve tube, the sleeve tube is fixed by using a rubber sleeve ring, and the drilling cores are processed into testing rock samples with different dimensions by using an angle grinder; inspection: the rock samples obtained outdoors are placed into a testing instrument, and a single-shaft compression testing and a triple-shaft compression testing are conducted on a drilling core testing member. The testing instrument has the advantages of being simple and portable, axial pressurizing and confining pressurizing can be conducted on a testing member, two functions of the engineering in-situ measuring of the single-shaft pressure resistance of the drill core and the triple-shaft pressure resistance of the drill core with a structural face are mainly achieved, and the in-situ testing of rock parameters is more convenient andpractical under the cooperation of APP software.
