Abstract
A composite support structure, a construction system, and a method, the composite support structure includes a plurality of arc plate rings that are longitudinally arranged along a roadway. A concrete fill steel tube support is arranged on an inner side or an outer side of each arc plate ring. The arc plate ring is formed by splicing a plurality of arc plates. Each concrete fill steel tube support is formed by splicing a plurality of steel pipe sections. The arc plate rings and the concrete fill steel tube supports are capable of jointly supporting walls of the roadway. The support structure has high bearing capability, high construction efficiency of a construction system, and low labor intensity.
