    Does the error in the test of the column depth tester cause the test data to be short, resulting in the failure of the construction quality of the test object?

    Release time:
    Page view

    Our company's column depth tester utilizes the impact elastic wave reflection characteristics, and successfully solves the key technical problems such as long duration of excitation signal excitation, internal resonance of cavity, large signal attenuation, and difficulty in identifying the reflected signal at the end of the column. It can effectively test the buried depth of pillars buried in soil, concrete, and other rock-in-situ. The equipment detection column is buried as non-destructive testing, no need to pull the pile, no damage to the roadbed, etc. According to the embedded conditions of the test object, the test results will have certain errors, which is unavoidable, but we promise that the test error does not exceed ±4% (or Not more than ±8cm). In general testing, if there is a short test result and design value, we recommend changing the line to review, after review, it can be found to be unqualified. For an object, we recommend multiple tests, and finally parse the best results, so as to avoid a test result that is too short or too long to mislead the construction quality. Therefore, the company's equipment will not appear to be short due to test errors, resulting in misjudgment of construction quality.
