[0002] In the field of construction engineering, the quality of water used in concrete is a key factor determining the durability and mechanical properties of concrete. As the Concrete Water Testing Institute points out, excessive chloride ions can cause steel corrosion, excessive sulfates can lead to sulfate erosion of concrete, soluble and insoluble substances affect setting time and strength, and abnormal pH values ​​may induce alkali-aggregate reaction (ASR). These problems directly threaten the safety and design life of building structures, so sampling equipment is needed to sample and test concrete. However, current concrete testing sampling equipment is not convenient for sampling at different locations, which leads to inconvenience in use. Therefore, we propose a concrete testing sampling device. Utility Model Content
