Radiation-proof wall for heat preservation of granary

The invention discloses an anti-radiation wall for heat preservation of a granary, which comprises a granary wall body, the granary wall body is sequentially provided with an outer sunscreen layer for reflecting and shielding strong light, a reinforcing layer for improving the bearing and supporting capacity of the granary wall body, a heat insulation layer for bidirectionally isolating the outside from the inside, a heat preservation layer for preserving heat in the granary, and an inner layer for improving the internal waterproof capacity and the lower moisture-proof performance of the granary from outside to inside. The granary wall is provided with a bottom heat dissipation mechanism for dissipating heat of the outer sunscreen layer, the outer sunscreen layer is an aluminum plate, the reinforcing layer is formed by pouring concrete after multiple layers of annular steel bars and vertical steel bars are spliced in a staggered mode, and the heat insulation layer is formed by fixing a plurality of heat insul
