Description

Technical Field

[0001] The invention relates to the technical field of magnetic ore dressing equipment for mineral processing engineering, and in particular to a filling device and method for controlling cracks in sluice piers. Background Art

[0002] Cracks in sluice piers are a common phenomenon. Almost all sluices that have been built or are under construction are cracked. Cracks affect the durability and safe operation of sluices. Pier cracks have certain characteristics and regularities. Piers on rock foundations are more likely to crack than those on soft foundations. During construction, the longer the interval between the bottom plate and the pier casting, the easier it is to crack. Pier cracks first occur at the bottom of the pier, and as time goes by, the cracks gradually develop upward. The main reason for cracks in piers is that the tensile stress generated by temperature changes after the concrete solidifies is greater than the ultimate tensile strength of the concrete. The necessary condition for the generation of temperature stress in pier concrete is that the concrete is completely constrained and embedded when the temperature rises and falls.
