Description

Technical Field

[0002] During the construction of municipal projects, temporary diversions of rivers and ditches are common. Currently, these temporary structures are mostly cast-in-place or prefabricated. Cast-in-place construction requires processes such as tying steel bars, erecting formwork, and curing. While this allows for various special-shaped structures, it takes a long time to construct. Furthermore, temporary structures must be dismantled after abandonment, making them unusable and requiring disposal as construction waste. This can cause environmental pollution, waste resources, and is not economically viable. Prefabrication requires temporary molds based on site conditions, making secondary use difficult and expensive. Furthermore, the heavy weight of the structure often necessitates the use of large machinery for installation and disassembly, requiring the establishment of temporary mechanical stations, which significantly increases construction costs.
