Underground diaphragm wall reinforcement cage production line arrangement and hoisting process

The invention discloses an underground diaphragm wall reinforcement cage production line arrangement and hoisting process. The process comprises the step of S2, arrangement and construction of a steelbar processing plant and a reinforcement cage production line, wherein the steel bar processing plant is arranged nearby a highway which communicates with an underground diaphragm wall construction site, the reinforcement cage production line is arranged in a right angle at one corner of the underground diaphragm wall construction site, and the area formed after the boundary of the reinforcementcage production line perpendicularly extends to the underground diaphragm wall construction site is a crawler crane operation area. According to the process, by optimizing the arrangement of the reinforcement cage production line, the site around an underground diaphragm wall is fully utilized, the process is not limited by the flatness of a surrounding terrain, a large terrain elevation difference between a reinforcement
