Fabricated energy-saving thermal insulation wall

The utility model discloses a fabricated energy-saving thermal insulation wall, and relates to the technical field of constructional engineering. The prefabricated wall comprises a prefabricated wall body, one end face of the prefabricated wall body is provided with a convex structure, the other end of the prefabricated wall body is provided with a concave structure, the convex structure and the concave structure are matched to form a wall body, and a sealing gasket is arranged between the convex structure and the concave structure. And when the convex structure is matched with the concave structure, sealing is formed by the sealing gasket. When the dovetail-shaped groove body is matched with the dovetail-shaped block body, the push plate extrudes the sealing gasket under the action of the spring to block the joint of the dovetail-shaped groove body and the dovetail-shaped block body, so that the problems that outdoor cold and hot air can be blown into a room, and indoor temperature is easy to escape from a g
