Description

Technical Field

[0001] The present application relates to the technical field of construction engineering, and in particular to a test mold based on high-density impermeability concrete. Background Art

[0002] Impermeable concrete refers to concrete that reduces infiltration channels and improves impermeability by increasing density and improving pore structure. The density, water repellency and impermeability of concrete are usually improved by adjusting the mix ratio of concrete, adding admixtures, using new types of cement, vibrating and compacting, and fully curing. In order to obtain the preparation process of impermeable concrete, a large number of impermeable concrete test blocks need to be prepared for testing and comparison.

[0003] The existing Chinese public patent (authorization announcement number: CN220179630U) mentions a high-density impermeability concrete test mold, including a bottom plate, a side mold and a top plate, the bottom plate is arranged with a side mold, the side mold is arranged with a top plate, the top plate is provided with a plurality of downward and outward inclined braces on both sides, the left and right sides of the side mold are provided with ear plates, the ear plates are provided with inclined holes that cooperate with the diagonal brace sets, the side mold includes a butted left mold and a right mold, the front and rear sides of the left mold and the right mold are both provided with sliders extending in the mold opening direction, and the bottom plate is provided with a slide groove that is nested with the slider, so that the left mold and the right mold fit the bottom plate and can slide along the left and right sides to open the mold respectively; the butt surfaces of the left mold and the right mold are both provided with a cavity, and when the mold is closed, the left mold, the right mold, the bottom plate and the top plate are combined to form a closed casting space. The utility model drives the side mold through the diagonal brace on the top plate to realize the mold opening and closing actions of the side mold, which can effectively solve the problems of difficulty in removing concrete test blocks and inconvenience in disassembling and assembling the test mold.

[0004] In the above-mentioned patent, the side molds are driven by the diagonal braces on the top plate to realize the opening and closing actions of the side molds, which can effectively solve the problems of difficulty in removing concrete test blocks and inconvenient disassembly and assembly of the test molds. However, in actual use, after pouring concrete in the test mold, the concrete cannot be shaken in time to expel the internal air, which can easily cause small gaps to appear inside the concrete after solidification, thereby reducing the density of the concrete and affecting subsequent test comparisons and daily use. For this reason, the present application provides a test mold based on high-density and anti-permeability concrete. Utility Model Content

[0005] The purpose of this application is to solve the problem that after pouring concrete in a test mold, the concrete cannot be shaken in time to expel the internal air, which easily causes small gaps to appear inside the concrete after solidification, thereby reducing the density of the concrete.
