Civil engineering wall reinforcing and supporting device

The civil engineering wall reinforcing and supporting device comprises a bottom plate, supporting plates are fixedly arranged on the two sides of one side of the top end of the bottom plate, a rotating rod is rotationally connected between the supporting plates through a bearing, a supporting plate is fixedly arranged on the surface of the rotating rod in a sleeved mode, a long sliding groove is formed in the supporting plate, and the long sliding groove is communicated with the supporting plate. An auxiliary supporting plate is arranged in the long sliding groove in a matched mode, a plurality of first threaded holes which are vertically arranged are formed in the inner side face of the supporting plate, and first threaded screwing rods are inserted into the first threaded holes in a threaded mode. Compared with the prior art, the supporting plate can be stored and aligned with the bottom plate, so that the storage space of the whole equipment is greatly reduced, before working, the auxiliary supporting plat
