Description

Technical Field

[0001] The utility model relates to the field of concrete pouring, in particular to a concrete pouring and forming device simulating a dynamic water state. Background Art

[0002] In hydraulic structures, bridge construction and other projects, concrete pouring is often carried out in a dynamic water environment. In a dynamic water environment, concrete pouring is easily affected by water flow, resulting in bubbles inside the concrete and even aggregate separation. The speed and intensity of the water flow have a significant impact on the pouring quality, density and durability of the concrete. Therefore, before conducting underwater construction, it is particularly important to simulate the concrete pouring under dynamic water conditions.

[0003] Existing technologies often rely on static water environments or artificially created flowing water states when simulating underwater concrete pouring and molding. However, these methods have some limitations. First, they are difficult to accurately control the size of the water flow, which limits the simulation of engineering construction conditions; second, due to the lack of effective methods to simultaneously simulate the concrete performance in dynamic and static water environments, it makes comparative analysis of test data difficult; finally, when using slump buckets for underwater concrete pouring simulation, two workers are usually required to work together, which not only increases the complexity of the operation, but also consumes time and manpower.

[0004] Therefore, it is necessary to develop a new type of concrete pouring and molding device that simulates dynamic water conditions to overcome the shortcomings of the existing technology. Utility Model Content
