Description

Auxiliary device and construction technology for the conversion of the lifting point of the steel cage of the underground continuous wall

technical field

The invention relates to the technical field of steel cage hanging point conversion, in particular to an auxiliary device and construction technology for the conversion of steel cage hanging points of an underground continuous wall.

Background technique

During the construction of the underground diaphragm wall, three lifting point conversions are required when the steel cage is hoisted. The last lifting point conversion requires passing the bar (positioning pole) through the steel cage, and placing the steel cage on the guide wall through the bar (positioning the pole). Since the hanging bar on the top of the steel cage also has the function of positioning the steel cage, its length is relatively long (usually about 2.5m), and the cable operator cannot complete the conversion of the lifting point on the ground.

The common practice is to first pass the bar (positioning pole) through the rebar cage, and place the rebar cage on the guide wall through the bar (positioning pole), and then the slinger climbs onto the rebar cage to convert the hanging point. The main disadvantages of the technology are as follows: 1. The cable operator needs to climb on the steel cage to operate, which is inefficient; 2. There are certain safety hazards. A fall from the air will cause serious hazard.
