DETAILED DESCRIPTION

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0030] As attached Figure 1 To Attachment Figure 6 As shown:

[0031] Embodiment 1: This embodiment provides an anchor rod and cable microbial corrosion experiment system, including a terminal control unit, and an experiment environment layout unit, an execution unit and a detection unit connected to the terminal control unit; the terminal control unit is used for overall control of the system and receiving experimental results; the experiment environment layout unit is used to arrange the environment of the anchor rod and cable experiment so that the parameters of the experiment environment meet the requirements; the execution unit is used to fix the anchor rod and cable and apply prestress, and at the same time drip a corrosion solution containing microorganisms to perform a corrosion experiment; the detection unit is used to detect the parameters of the experiment environment and the corrosive substances, as well as the corrosion condition of the anchor rod and cable after the experiment, and transmit the data to the terminal control unit.

[0032] Specifically, the experimental environment layout unit includes a disinfection module, a deoxygenation module, an oxygen supply module, a waste liquid recovery module, a high temperature treatment module, a residue collection module, and a microbial cultivation module.

[0033] Specifically, the execution unit includes a clamping and fixing module, a temperature and humidity adjustment module, a stress application module, and a corrosion solution dripping module.

[0034] Specifically, the detection unit includes a microbial activity detection module, an H2S gas detection module, a temperature and humidity detection module, a visual detection module, a stress detection module and a displacement detection module.

[0035] As can be seen from the above, before the experiment, the anchor rod and anchor cable to be tested are fixed by the clamping and fixing module, and the experimental site is disinfected by ultraviolet irradiation through the disinfection module to ensure that the experimental site is a sterile environment. At the same time, the microbial cultivation module is disinfected by the disinfection module to ensure that the microbial cultivation module is a sterile environment. The temperature and humidity of the microbial cultivation module are detected by the temperature and humidity detection module, and adjusted by the temperature and humidity adjustment module. Then, the microorganisms are cultivated by the microbial cultivation module, and the oxygen requirements of different types of microorganisms are met by the deoxygenation module. The activity and concentration of the microorganisms are detected by the microbial activity sensor to meet the requirements of the experiment. For example, typical corrosive microorganisms, sulfate-reducing bacteria (SRB), need to be cultivated and survive in an anaerobic environment, and will produce H2S gas during the corrosion process;

[0036] When conducting anaerobic microbial experiments, after the anaerobic microorganisms are cultured using the microbial culture module through the above operations, nitrogen is filled into the experimental site through the deoxygenation module, and the air in the experimental site is completely exhausted for multiple cycles to ensure that the experimental site is an anaerobic environment.

Then, the hydrogen sulfide gas concentration of the experimental site before the experiment is detected through the H2S gas detection module, and the appearance of the anchor rod and cable before the experiment is identified and recorded through the visual detection module;

[0037] After the preparation work is completed, the stress application module is used to apply axial prestress to the anchor bolts and cables. The stress detection module is used to accurately control the size of the axial prestress applied to the anchor bolts and cables. Then, the corrosion solution dripping module is used to drip the corrosion solution containing microorganisms on the anchor bolts and cables for corrosion. During the process, the flow rate and flow rate of the corrosion solution are accurately controlled. The stress detection module and the displacement detection module are used to detect the parameter changes during the anchor bolt and cable experiment. The H2S gas detection module is used to detect and record the concentration of hydrogen sulfide gas after the experiment in the experimental site in real time, observe the parameter changes of the H2S corrosion gas, understand the changes in the environment during the corrosion process, and then the visual detection module is used to detect the anchor bolts and cables. The appearance status of the anchor rods and cables after the experiment is identified and recorded. By comparing the stress, displacement, H2S gas concentration and appearance change data of the anchor rods and cables before and after the experiment, the microbial corrosion resistance test experiment of the anchor rods and cables is completed. At the same time, the waste liquid after the corrosion dripping operation will be centrally collected and treated through the waste liquid recovery module, and the debris corroded and detached from the anchor rods and cables during the corrosion dripping operation will be collected through the residue collection module. The staff can further increase the experimental comparison data and improve the accuracy by testing the residue and debris. Then, the waste liquid is subjected to high-temperature treatment by the high-temperature treatment module to kill the harmful bacteria therein, which is convenient for the staff to carry out subsequent discharge treatment.
