Description

Technical Field

[0001] The utility model discloses a pressurizing device for testing and detecting raw materials, and relates to the field of highway engineering. Background Art

[0002] In the prior art, highway engineering refers to the survey, measurement, design, construction, maintenance, and management of highway structures. Cement is widely used in highway construction. Before the construction of highway engineering, it is necessary to perform pressure testing on the selected raw material cement. The early pressure testing is related to the quality of the finished products of the later highway engineering construction. There are two testing standards for cement, namely compressive strength and flexural strength. The usual testing method is to put the cement blocks made of raw materials in advance into the pressure testing device for pressure testing.

[0003] According to a pressurizing device for testing raw materials for highway engineering disclosed in the patent with patent announcement number CN216669527U, the device avoids the situation in which the existing testing equipment provides force only on one side, improves the testing effect and efficiency, and at the same time reduces the load on the equipment and extends its service life. However, when performing pressurized testing in actual applications, there is generally a lack of a fixing mechanism for the cement blocks. During the testing process, the cement blocks may be offset, which will cause uneven force on the cement blocks and reduce the accuracy of the device's detection. At the same time, there is a lack of a protective mechanism, which may cause the cement blocks to splash during the testing process, reducing the safety of the device. Utility Model Content
