Description

Technical Field

[0001] The utility model relates to a hoisting tool, more specifically to an aqueduct hoisting structure. Background Art

[0002] As the scale of water conservancy projects continues to expand, there are more and more restrictions on the construction of cast-in-place aqueducts, and prefabricated hoisting construction technology has been increasingly used in aqueduct construction. Prefabricated hoisting avoids the risks brought by high-altitude operations, speeds up the construction progress, and ensures the construction quality of the trough body and prefabricated components. However, when prefabricating the trough body, traditional prefabricated hoisting requires pre-embedding 4 pull rings on the trough body in advance, and then directly connecting the hoisting rope to the pull ring for hoisting operations. This method of pre-embedded pull rings makes it impossible to guarantee the quality of the concrete at the pre-embedded pull rings when prefabricating the trough body. At the same time, problems such as trough body damage are prone to occur during the hoisting process, which seriously affects the appearance quality of the aqueduct and causes huge economic losses.
