Method for quickly connecting heavy steel with pipe curtains on basis of advanced supporting

The invention discloses a method for quickly connecting heavy supports with pipe curtains on the basis of advanced supporting. The method comprises the steps that the first-layer step middle pipe curtain is connected with a vertical support and a horizontal support, and the horizontal support of a first-layer step adopts two H-shaped steel parts for forming a double-spliced cross support; verticalsupports in other steps all adopt two section steel parts for forming double-spliced vertical supports connected through bolts, the upper and lower ends of each double-spliced vertical support are connected and spliced through reserving bolt holes, and the lower end of the double-spliced vertical support in the lowest-layer step is welded to the corresponding pipe curtain; the pipe curtains in other steps are connected with the corresponding horizontal supports, and the horizontal supports in other steps adopt single H-shaped steel parts for forming single-spliced cross supports. The providedmethod for quickly connec
