1. A composite supporting structure combining fabric-form bag-behind-wall grouting and high-strength support frame, comprising multiple sections of composite supporting units sequentially arranged along a longitudinal direction, each of the composite supporting units comprises support frames, wherein 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; the circumferential fabric-form bags and the longitudinal fabric-form bags form an enclosed structure outside the support frames; each of the support frames corresponds to one circumferential fabric-form bag, and ends of two circumferential fabric-form bags are connected to each other through one longitudinal fabric-form bag; adjacent support frames are connected to each other through a plurality of connecting rods arranged at intervals along a circumferential direction;
wherein, the circumferential fabric-form bags are arranged between a bolting-steel mesh-shotcreting support and the support frames; a fabric-form bag-grouting reinforced concrete structure is formed by pouring concrete into the circumferential fabric-form bag and the longitudinal fabric-form bags; and
two layers of reinforcing steel mesh sheets are respectively arranged in the circumferential fabric-form bags and the longitudinal fabric-form bags, and the two layers of the reinforcing steel mesh sheets are connected to each other through first high-strength fiber bundles; adjacent circumferential fabric-form bags are connected, the circumferential fabric-form bags, the longitudinal fabric-form bags and the support frame are connected respectively by second high strength fiber bundles.
