Rainwater-corrosion-preventing reinforcement method for existing immature soil wall

The invention belongs to the technical field of immature soil construction reinforcement of civil engineering and particularly discloses a rainwater-corrosion-preventing reinforcement method for an existing immature soil wall. The method comprises the following steps that firstly, rebars are distributed on the existing immature soil wall; then, floating soil on the surface of the existing immature soil wall is cleared away; thirdly, steel wire gauzes are hung on the two sides of the immature soil wall through the rebars respectively and bundled to the rebars through bundling wires; the two sides of the existing immature soil wall are coated with viscous fiber mortar to form viscous fiber mortar face layers, and the rebars and the steel wire gauzes are covered with the viscous fiber mortar face layers. The reinforcement method has the advantages that the dead load of the existing immature soil wall is not increased and the size of the existing immature soil wall is not changed. According to the method, the con
