Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of concrete pouring, in particular to a concrete pouring device and method for reinforced concrete engineering. BACKGROUND

[0002] Reinforced concrete structures are widely used in the field of construction engineering due to their high strength, durability, and good compression resistance. Concrete pouring is a critical link in reinforced concrete construction, which directly affects the overall quality and safety of the structure. High-quality concrete pouring can ensure that concrete and steel bars are closely combined to form a solid structure system, thereby effectively bearing various loads of buildings and resisting external environmental factors.

[0003] Traditional concrete pouring devices often have uneven mixing when mixing concrete raw materials. Concrete raw materials include cement, sand, water, and other components. If the mixing is not sufficient, it will lead to uneven distribution of internal components. For example, sand may accumulate in local areas, while cement paste is less distributed, which will affect the strength and uniformity of the concrete. In actual construction, such uneven concrete may form weak points in the structure, reducing the load-bearing capacity and durability of the structure.

[0004] During the transportation of concrete from the mixing device to the pouring position, the discharging place is prone to blockage. This is because concrete has a certain viscosity, especially when the sand content is high or the water-cement ratio is low, the flowability of the concrete becomes poor, and sand particles may accumulate at the discharge port, causing the discharge channel to narrow or even completely block.

[0005] Based on this, the present application provides a concrete pouring device and method for reinforced concrete engineering. SUMMARY
