Prefabricated side slope

The invention discloses a prefabricated side slope, and relates to the field of road engineering. The prefabricated side slope comprises a slope body, a slope surface is obliquely arranged on the slope body, a dovetail strip is vertically arranged on one side of the slope body, and a groove allowing the dovetail strip to be embedded therein and a dovetail groove communicating with the lower end ofthe groove and allowing the dovetail strip to be embedded therein are formed in the other side of the slope body; and a sliding hole communicating with the groove is formed in the slope surface, a sliding rod used for pressing the upper end face of the dovetail strip is connected into the sliding hole in a sliding mode, and a locking part used for fixing the sliding rod is arranged in the slidinghole. The construction method has the following advantages and effects that by arranging the splicing type prefabricated side slope, construction of side slopes on two sides of a road is completed, traditional piling or layin
