Description

Technical Field

[0001] The invention relates to the technical field of hoisting, and in particular to a hoisting device for a steel cage of a road engineering project. Background Art

[0002] The main role of the steel cage is the same as the stress on the longitudinal steel bars of the column. It mainly plays a tensile role. The compressive strength of concrete is high but the tensile strength is very low. It restrains the concrete of the pile body so that it can withstand a certain axial tension. During the construction of bridges or high-rise buildings, the foundation may be required to be piled according to requirements. The method is to use machine punching and water drilling, and the hole depth meets the design requirements. Then lower the steel cage into the pile hole, and then insert the conduit for concrete pouring. When the concrete structure is a columnar or strip component, the central part does not need to be reinforced, and steel bars are only arranged under the surface of the concrete component that contacts the air. This component is independent, and the steel bars set around this component are pre-made. This is a steel cage. Usually, pre-made steel structures such as bored piles, bored piles, and columns are called steel cages.
