Technical Field

[0001] The utility model belongs to the technical field of grouting material fluidity testing devices, and in particular relates to a grouting material fluidity testing device. Background Art

[0002] There are two main methods for testing the fluidity of grouting materials: one is to measure the flow value of the grouting material, and the other is to test the fluidity of the grouting material within 30 minutes. Fluidity refers to the flow performance of the grouting material within a certain period of time. The fluidity is usually used to determine the quality of the grouting material. If the fluidity of the grouting material is not enough, it will affect the quality of the grouting project.

[0003] One of the methods for detecting the fluidity of grouting materials is the funnel method. The bottom of the funnel is sealed, and the grouting material is poured into the funnel. The timing is started. The bottom of the funnel is opened and the grouting material leaks out. The time (T) when the grouting material completely leaks out of the funnel is recorded, and the fluidity F value is calculated according to the relevant formula (F=50 / T); in the above operation, the grouting material is generally lifted up and poured into the funnel manually, and the bottom of the sealed funnel is opened and the timing is started. The whole process is manual operation, which is relatively cumbersome, and the leaked material cannot be collected. When it is necessary to measure multiple times and calculate the average value, it is relatively cumbersome and laborious; when the fluidity of the grouting material is measured multiple times, there is a problem of no convenient design for loading the grouting material. For this reason, the present application proposes a fluidity testing device for grouting materials. Utility Model Content
