Description

Technical Field

[0001] The utility model relates to the technical field of box culvert moulds, in particular to a prefabricated box culvert processing mould. Background Art

[0002] Box culvert refers to a culvert with a reinforced concrete box-shaped pipe section. The box culvert consists of one or more square or rectangular sections, generally made of reinforced concrete or masonry, but reinforced concrete is more widely used. When the span is less than 4m, a box culvert is used. For pipe culverts, reinforced concrete box culverts are a cheap substitute, and the piers, upper and lower plates are all cast in unison. The casting of the box culvert is very troublesome. Due to its hollow and thin cylindrical structure, it cannot be cast in one piece when it is handed over, otherwise it will cause gaps inside, making the inner wall of the culvert insufficiently supportive, and casting in steps cannot ensure that other surfaces can be connected intact.
