Thermal-insulation and heat-preservation wall

The invention provides a thermal-insulation and heat-preservation wall, and relates to the technical field of energy saving of buildings. A sound insulation layer (2) is arranged on the inner side of a wall body (1) of the thermal-insulation and heat-preservation wall, a cement heat-preservation layer (3) is arranged on the outer layer of the wall body (1), steel wire mesh (4) is arranged inside the cement heat-preservation layer (3), an anti-corrosion layer (5) is arranged on the outer layer of the cement heat-preservation layer (3), and a thermal-insulation layer (6) is arranged on the outer side of the anti-corrosion layer (5). The thermal-insulation and heat-preservation wall is simple in structure, high in construction efficiency, longer in service life, and low in cost, and construction time is saved.
