The gas cabinet consists of a main body and an auxiliary elevator,and the auxiliary elevator shaft is dismantled by segmented lifting.When dismantling the gas cabinet body,the gas cabinet columns were divided into two groups:jack columns and non jack columns.The hydraulic cluster jacks were used to alternately apply force to the two groups of columns,successfully achieving the"reverse dismantling method"for the overall lowering of the gas cabinet,proving the feasibility of the technical solution in practical applications.Compared with traditional demolition methods,it reduces high-altitude operations and large-scale lifting,lowers demolition safety risks,and has high economic benefits,providing a reference for the demolition of similar equipment.
