One is the macroscopic direction parameters, such as compressive strength, flexural strength, etc., and the other is the microscopic direction parameters, such as chlorine content, etc. For macroscopic direction parameters, it is generally necessary to test block products, and for microscopic direction parameters, it is generally necessary to perform crushing sampling. The existing crushing sampling device has many components, a complex structure, and a high manufacturing cost. In addition, the process and method of controlling the insertion depth of the drilling position in the concrete are complicated, which causes many adverse effects during use. Utility Model Content
