Supporting method for reverse construction of adjacent deep foundation pits of steel rolling mill

The invention relates to the situation that the drawing sequence of a construction site is inconsistent with that of a designer, in particular to a supporting method for reverse construction of adjacent deep foundation pits of a steel mill. The method is characterized by comprising the following steps: constructing and supporting a position with the digging depth of 4.8-6.0 m of a foundation pit; construction and supporting are conducted on the position, with the digging depth being 6.0-7.0 m, of the foundation pit; constructing and supporting a position with the excavation depth of 7.0-8.0 m of the foundation pit; constructing and supporting the position with the excavation depth of 8.0-9.0 m of the foundation pit; constructing and supporting the position, with the excavation depth of 8.3 m, of the foundation pit; constructing and supporting the position, with the digging depth of 10.62 m, of the foundation pit; foundation pit excavation foundation construction; by the adoption of the steps, related technica
