Description

Technical Field

[0001] The invention relates to the technical field of concrete segment strength detection, and in particular to a concrete segment strength detection device. Background Art

[0002] In modern urban infrastructure construction, precast concrete segments are widely used as supporting structures in subway tunnels, underground pipelines and other projects. The strength of concrete segments is one of the key factors to ensure the safe and stable operation of these projects. Therefore, concrete segment strength detection devices play an important role in project quality control. However, existing concrete segment strength detection devices have many shortcomings in practical applications, especially in terms of detection accuracy and repeated correction. These problems seriously affect the reliability of the test results and the safety of the project.

[0003] Existing concrete segment strength detection devices have obvious deficiencies in detection accuracy. The strength detection of concrete segments usually involves multiple indicators such as compressive strength and flexural strength. The accurate measurement of these indicators is crucial to evaluating the quality of the segments. However, existing detection devices often rely on traditional pressure testing methods, which are easily affected by multiple factors in actual operation, such as loading speed, loading method, sensor accuracy, etc. Slight changes in these factors may cause fluctuations in the test results, thereby affecting the accuracy of the test. For example, when conducting a compressive strength test, if the loading speed is uneven or the loading points are unevenly distributed, large errors may occur in the test results. Such inaccurate test results not only fail to truly reflect the actual strength of the concrete segments, but may also mislead the construction party to use unqualified segments in the project, burying safety hazards.

[0004] Existing concrete segment strength testing devices also have obvious defects when dealing with tilt problems. In the actual testing process, the concrete segment may tilt due to improper placement or inaccurate equipment adjustment. This tilt not only affects the accuracy of the test results, but may also cause damage to the segment during the test. However, existing testing devices often lack an effective tilt correction function and are unable to automatically adjust the position of the segment to keep it level before testing. For example, when the segment is unevenly placed on the test bench, the existing device cannot automatically detect and correct the tilt, but relies on manual adjustment by the operator. This manual adjustment is not only inefficient, but also prone to human errors, resulting in inconsistent test results. In addition, even after manual adjustment, it is difficult to ensure that each adjustment can achieve the optimal horizontal state, which affects the repeatability and reliability of the test.

[0005] The existing concrete segment strength testing devices also have a large gap in the degree of automation. In large-scale projects, a large number of concrete segments need to be tested for strength. Manual operation is not only time-consuming and laborious, but also prone to errors caused by fatigue. Although the existing testing devices have partially achieved automated operation, there is still much room for improvement in testing speed and stability. For example, some equipment will vibrate and deviate during high-speed testing, resulting in inaccurate test results.
