A multi-function ecological exterior wall and a preparation method therefor. A ceramic plate of a ceramic heat insulation waterproof layer (3) is prepared, a ceramic sound absorption plate of a sound absorption layer (1) is prepared, and the ecological exterior wall is installed: applying a cement screed to a building wall surface, painting a cement bonding layer (2), and then pasting the cement heat insulation waterproof plate on the cement bonding layer (2), painting the cement bonding layer (2) on the ceramic plate, and re-pasting the cement sound absorption plate of the sound absorption layer (1) on the cement bonding layer (2). During the pasting, a gap of 3-5cm for placing pipelines (5) is reserved on the top edge of the uppermost row of the ceramic plates in each floor of the building, then a thread steel anchor rod (6) is nailed slantly from the surface of the ceramic plate of the sound absorption layer (1) into the wall, the pipelines (5) are mounted and fixed along the reserved gap on the ceramic plate of the sound absorption layer (1), and at last, green plants are planted on the surface of the ceramic plate of the sound absorption layer (1). Solid wastes such as coal ash, coal gangue and common materials which are quite easy to obtain are used in the method, and the method is low in cost, saves resources, is environmental protecting and is easy to operate. |
