Hoisting construction safety method for reinforcement cage of underground continuous wall

Abstract

The invention belongs to the technical field of underground engineering construction, and discloses a hoisting construction safety method for a reinforcement cage of an underground continuous wall. A260t crane and a 150t crane are commanded to be transferred to a hoisting position, hoisting workers correspondingly installed unloading buckles of hoisting points; the installation conditions of steel wire ropes of the two cranes and gravity centers of stress are checked, and the reinforcement cage is horizontal hoisted by the two cranes simultaneously; after a lower reinforcement cage is hoistedto be 0.3m to 0.5m away from the ground, the 260t crane lifts a hook after whether the lower reinforcement cage is stable or not is checked, and an auxiliary machine is commanded to hook in a matchedmode at any time according to the distance from the tail of the lower reinforcement cage to the ground; after the reinforcement cage is hoisted, the 260t crane rotates leftwards (or rightwards), andthe 150t crane rotates to a proper position, so that the reinforcement cage is perpendicular to the ground; the hoisting workers are commanded to unload the hoisting point shackles of the 150t crane on the reinforcement cage, and then the hoisting worker are away from the hoisting operation range; the 260t crane is commanded to put the reinforcement cage into the groove and locate the the reinforcement cage; and the whole body of the reinforcement cage is leveled after descending in place, and the descending process of the reinforcement cage is finished.

Description

technical field [0001] The invention belongs to the technical field of underground engineering construction, and in particular relates to a construction safety method for hoisting and hoisting a reinforcement cage of an underground diaphragm wall. Background technique [0002] At present, the closest existing technology: In the field of super high-rise building construction, underground diaphragm wall has become an effective anti-seepage, soil retaining and load-bearing function technology in underground engineering and deep foundation construction, and the hoisting of underground diaphragm wall reinforcement cage is very important a part of. The traditional hoisting method of the reinforcement cage of the underground diaphragm wall usually adopts single-point lifting, which is easy to cause the instability of the reinforcement cage, and the reinforcement cage is easy to collide with the guide wall, so that the reinforcement cage is deformed, which not only affects the const...

AI Technical Summary

Problems solved by technology

[0003] To sum up, the problems existing in the prior art are: the existing underground diaphragm wall reinforcement cage hoisting construction time is long, which makes the construction period long and increases the construction cost
