Description

Technical Field

[0001] The present invention relates to the technical field of hoisting equipment, in particular to hoisting equipment for the construction of prefabricated underground continuous walls. Background Art

[0002] A diaphragm wall, also known as an underground diaphragm wall, is a foundation construction technique that uses a trenching machine to excavate a narrow, deep trench along the perimeter axis of the deep excavation, using slurry as a protective wall. After the trench is cleared, a steel cage is lowered into the trench, and underwater concrete is poured using a conduit method to create a unit trench section. This is done section by section, or the prefabricated underground continuous wall is directly placed in the trench after the trench is cleaned, and concrete is poured at the joint. The prefabricated underground continuous wall needs to be lifted by a lifting equipment first. In the existing technology, a gantry crane is generally used to lift the prefabricated underground continuous wall, and then the prefabricated underground continuous wall is placed in the trench. However, when the gantry crane lifts the prefabricated underground continuous wall, the prefabricated underground continuous wall needs to be fixed. Generally, one side of the prefabricated underground continuous wall is lifted manually, and the lifting clamp at the bottom of the gantry crane is fixed on both sides of the prefabricated underground continuous wall, and then the prefabricated underground continuous wall is lifted and placed in the trench. The overall operation is relatively inconvenient, and the operation of lifting the prefabricated underground continuous wall increases the labor intensity of the workers.
