Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of construction equipment, in particular to a concrete pouring funnel. Background Art
[0002] In the process of construction, concrete pouring is an important task, which involves transporting concrete slurry to the parts that need to be filled or reinforced through specific equipment or tools. Traditional concrete pouring usually pours directly downward at the pouring port, which cannot adapt well to the pouring needs of different heights and distances. If the pouring height is too high, it will cause "segregation" or "sedimentation" during the pouring process.
[0003] "Segregation" refers to the separation of different components in concrete slurry (such as concrete particles, aggregates, water, etc.) due to gravity or other factors during the pouring process, resulting in uneven distribution of the physical and chemical properties of each part. During pouring, the water and other light components in the concrete slurry tend to float, while the heavy components such as concrete particles and aggregates tend to sink, thus forming an area with lower density and poorer strength at the lower end of the poured body.
[0004] "Sedimentation" refers to the phenomenon that concrete particles or aggregates settle downward under the action of gravity. During pouring, due to the limited fluidity of the concrete slurry, concrete particles and aggregates tend to settle downward under the action of gravity, resulting in a lower density of concrete at the lower end. Therefore, a concrete pouring funnel with an adjustment function is needed to improve the pouring efficiency and adapt to different work scenarios.
[0005] Due to the above two phenomena, the concrete poured at the lower end is easily not solid, thus affecting the quality of concrete pouring.
[0006] Based on this, the applicant proposed a concrete pouring funnel to solve the above technical problems. Utility Model Content

[0026] 1. Adapt to the needs of different heights and distances of perfusion: The design of the adjustable length pipe allows the height and distance of the funnel outlet to be adjusted according to the specific working scenario, which effectively solves the problem that the traditional perfusion method cannot adapt to the needs of different heights and distances of perfusion. This can not only improve the perfusion efficiency, but also reduce the difficulty and labor intensity of manual adjustment.
[0027] 2. Reduce the "segregation" phenomenon of concrete slurry: Since the position of the pouring port can be accurately controlled, the effect of gravity on the separation of concrete slurry components caused by height difference is avoided.
