Polyurethane thermal insulation moisture preservation inorganic safeguard integration system for dam

The utility model relates to a polyurethane thermal insulation moisture preservation inorganic safeguard integration system for a dam. An upstream water face thermal insulation moisture preservation layer and an upstream water face protection layer are arranged on a facing water base face of a cam body outside in sequence. A downstream water face thermal insulation moisture preservation and a downstream water face protection layer are arranged on a downstream water base face of the cam body outside in sequence. The upstream water face thermal insulation moisture preservation layer and the downstream water face thermal insulation moisture preservation layer are made of rigid foam polyurethane pasting layers. The upstream water face protection layer and the downstream water face protection layer are made of polymer anti-crack mortar layers. Rigid foam polyurethane material spraying technology is adopted so that rigid foam polyurethane material forms a whole on a cam surface, the whole is strong in binding force
