Description

Technical Field

[0001] The present invention relates to the technical field of concrete testing, and particularly to an integrated device for making and curing concrete specimens. Background Art

[0002] Existing concrete specimen making devices have many deficiencies in practical applications. Traditional devices often have a single function and lack an integrated process from concrete mixing, sample making to curing and storage, resulting in a cumbersome operation process and low efficiency. Specifically, the existing technologies have the following main disadvantages: First, the vibration process lacks refined control, the vibration effect is uneven, which easily affects the quality of concrete specimens. At the same time, traditional vibration methods often rely on manual operation, with a large labor intensity and it is difficult to ensure the consistency and stability of vibration. Second, the curing and transportation processes are greatly affected by environmental factors, especially the lack of a constant temperature and humidity environment, which causes problems such as cracking and deformation of concrete specimens during the curing process. In addition, traditional curing methods often require a large amount of space and have a long curing cycle, affecting production efficiency and space utilization. Moreover, the existing devices are not closely connected between various links such as sample making, transportation, curing and storage, with a low degree of automation and require a large amount of manual intervention, which not only increases labor costs but also easily causes operation errors, affecting the production efficiency and accuracy of concrete specimens. Finally, traditional devices are prone to damage concrete specimens during the sample demoulding and extraction processes, affecting the integrity of the specimens and the accuracy of subsequent test results.
