The invention discloses construction complete equipment for an erosion-resistant protective layer of a concrete foundation in a salty soil zone. The construction complete equipment comprises a grouting pump and an erosion-resistant slurry injection device; the grouting pump and the erosion-resistant slurry injection device are connected through a grouting tube; the erosion-resistant slurry injection device is used for grouting erosion-resistant slurry into a position between the concrete foundation and a surrounding stratum; the erosion-resistant slurry injection device comprises a grouting main pipeline which is connected to the grouting tube; and a plurality of joints are further connected on the grouting main pipeline, and are connected to grouting branch pipelines. The construction complete equipment disclosed by the invention can grout an erosion-resistant material between the periphery of underground construct concrete and a surrounding bottom layer; and the erosion-resistant protective layer is formed at a concrete outer layer. The construction complete equipment solves the problems of high engineering construction cost, not strong adaptability and a complex construction process of an existing erosion-resistant protective technology.
