Description

Technical Field

[0001] The utility model relates to the technical field of bridge concrete monitoring, in particular to a concrete strength monitoring device. Background Art

[0002] A bridge generally refers to a suspended structure that allows vehicles and pedestrians to pass smoothly. It is necessary to regularly monitor and evaluate the condition of the bridge structure. One of the items of regular bridge monitoring is to use a concrete strength testing device to test the compressive strength of the bridge concrete.

In addition, the sampling operation will cause damage to the concrete surface, which is very likely to affect the structural stability. In addition, sampling is limited, and the accuracy of monitoring is also easily affected. Utility Model Content
