Description

Technical Field

[0001] The invention relates to the field of geotechnical test detection, and in particular to a geotechnical test detection system. Background Art

[0002] The sand filling method equipment for geotechnical testing: sand filling cylinder, calibration tank, and base plate test tools are tested according to the steps in T0921-2019 pit digging and sand filling test compaction method in JTG3450-2019 field test regulations for highway roadbed. The ring knife method equipment for geotechnical testing: ring knife, ring cover, directional cylinder, timing system (guide rod, drop hammer, handle) tools are tested according to the steps in T0923-2019 ring knife test compaction method in JTG3450-2019 field test regulations for highway roadbed.

[0003] At present, the sand filling method and ring knife method of geotechnical testing for testing the compaction of roadbed and pavement and backfill trench projects are still at the stage of manual data recording and manual calculation of results, and the on-site testing is all paper records. The invention of this geotechnical testing system realizes data entry of the entire experimental process and automatic calculation of results by the system, which improves efficiency and avoids calculation errors.

[0004] On-site inspections are all recorded in paper form, which takes up physical space and is easy to lose. The invention of this geotechnical test and detection system realizes data digitization, which can be saved in the system, on the computer hard drive, or uploaded to the data management platform.

[0005] In traditional geotechnical tests, the sand calibration test and the sand filling compaction test are often conducted separately, which makes the test process more complicated, time-consuming and inefficient. During the test operation, due to the lack of unified specifications and standards, human errors are prone to occur, affecting the accuracy and reliability of the test results.

[0006] There are also problems with the management of test data. In traditional methods, data recording and storage are relatively scattered, which is not convenient for unified management and query, which brings difficulties to subsequent data analysis and engineering quality evaluation. Moreover, in terms of operation interface and language settings, there is a lack of flexibility and personalization, which cannot meet the needs of different users and reduces the ease of use of the system.

[0007] In terms of sample box management, there is no complete management system, which leads to the creation, search and deletion of sample boxes being not standardized and convenient, and easily leading to confusion and data loss.

[0008] In addition, the traditional geotechnical test method is not satisfactory in terms of project quality control. Since the accuracy and timeliness of the test results cannot be guaranteed, it is difficult to find quality problems in the project in time, which may lead to hidden dangers in project quality and increased costs. Therefore, we propose a geotechnical test detection system. Summary of the invention
