Description

Technical Field

[0001] The utility model belongs to the technical field of concrete detection, and particularly relates to a concrete detection device for highway construction. Background Technique

[0002] After highway construction, it is necessary to take samples of the concrete on the road surface for detection. Before testing the concrete, the concrete will be prepared into standard test blocks. For the test method of load, for concrete, the compressive test mainly measures the axial compressive strength per unit volume of concrete, which is an important test method for concrete structures.

[0003] When conducting a compressive test on a concrete test block, a pneumatic pressing block is used to conduct the compressive test on the concrete test block. Since the concrete test block is mostly exposed during the compressive test, when the pressure exceeds the bearing range of the test block, the test block will crack and break, and the flying fragments may accidentally injure people or objects around. Therefore, a concrete detection device for highway construction is needed, which can cover the test block during detection to reduce the probability of accidental injury to people or objects caused by the flying of the test block. Summary of the Utility Model
