Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an expansion stress testing device for an expansion type grouting material. Background Art

[0002] Expansive grouting material is a special material widely used in construction. Its main features are high fluidity and expansion. It can expand and solidify quickly after being injected into cracks or holes, thereby filling the gaps and reinforcing the structure. In the field of construction, expansive grouting materials are often used in projects such as foundation reinforcement, tunnel anti-seepage, and underground engineering plugging. This material can effectively improve the stability and safety of buildings. Its working principle is to generate gas through chemical reactions, so that the slurry volume expands, fills the gaps and tightly combines with the surrounding structure, thereby enhancing the overall bearing capacity and anti-seepage performance.

[0003] In the production process of expansive grouting materials, an expansion stress test is required. First, a powdered expansion agent needs to be poured into the mold, and then water or a catalyst is added. At this time, the expansion agent will expand and solidify in the mold due to its own property of swelling when it comes into contact with water. After solidification, the object to be tested for the expansion stress test can be obtained, and then the expansion stress test can be started again. However, if the stirring is uneven or air intrudes, bubbles may exist inside the object to be tested. Therefore, in the subsequent expansion stress test process, the bubbles may affect the overall strength and force uniformity of the material, thereby causing inaccurate test data.

[0004] Therefore, in response to the above problems, we need to propose an expansion stress testing device for expansive grouting materials. Utility Model Content

[0024] The two sides of the inner cavity of the connecting shell 1 are fixedly connected with knocking blocks 2. The knocking blocks 2 are located in the inner cavity of the connecting shell 1. Their function is to knock on the sides of the mold shell 4 to promote the bubbles to rise from the expansion grouting material and discharge from the mold shell 4. The knocking blocks 2 are arranged in a cone shape.
