Abstract: The present invention provides a composite supporting structure combining fabric-form bag-behind-wall grouting and high-strength support frames and a construction method thereof, relating to the field of underground engineering support. The composite supporting structure comprises multiple sections of composite supporting units sequentially arranged in a longitudinal direction, wherein each of the composite supporting units comprises support frame, circumferential fabric-form bags are arranged outside top plate sections and side sections of the support frames, and longitudinal fabric-form bags and longitudinal supports are arranged in an alternating manner outside bottom plate sections of the support frames. The present invention forms an active-passive combined full-section composite high-strength supporting structure that may solve the problems of support difficulties such as high ground pressure, strong disturbance and the like of deep wells.

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.
