Ecological outer wall with functions of water storage, evaporation cooling and heat insulation

The utility model discloses an ecological outer wall with functions of water storage, evaporation cooling and heat insulation. The ecological outer wall comprises heat insulation shells and water storage shells, wherein the heat insulation shells and the water storage shells are arranged on the outer wall, seal and hollow structures for heat insulation are formed between the interiors of the shells and a mortar layer, and according to the water storage shells, the sunk interiors of the shells face upwards to form water storage cavity structures. According to the waste reclamation natural ecological outer wall building, the kitchen shells and other wastes are used as raw materials and are ingeniously arranged on the mortar layer, the multiple heat insulation shells form multiple small hollow heat insulation and heat preservation cavities to insulate indoor and outdoor temperature transfer, the water storage shells form multiple small water storage pools to achieve recovery and utilization of rainwater and evaporation cooling, and therefore the heat island effect of a city is reduced. The shells in different combination and array modes continue civilization and wisdom of ancient times and build natural ecological human landscape. By means of waste reclamation utilization of kitchen shells, tapestry bricks are saved, cost is reduced, and destruction and pollution to the natural environment by tapestry brick production are reduced.
