Underground auxiliary reinforcing structure for iron tower installation

The invention provides an underground auxiliary reinforcing structure for iron tower installation, and relates to the field of iron towers. The underground auxiliary reinforcing structure for iron tower installation comprises a cement base buried in the ground and a power transmission iron tower body installed on the cement base, a device frame is embedded in the cement base, and the periphery of the device frame fixedly communicates with four fixing cylinders distributed in a circumferential array mode. Through the arrangement of the device frame, the fixing cylinder, the transverse telescopic reinforcing mechanism, the vertical reinforcing mechanism, the threaded mounting hole and other structures, multiple reinforcing can be conducted on the cement base, then the pouring area of the cement base can be properly reduced, and the stability of connection between the cement base and the ground can be guaranteed through cooperation of the multiple reinforcing mechanisms; construction in the deep mountain area is
