Cantilever-type retaining wall adopting spigot-and-socket prefabricating and assembling process

The invention provides a cantilever-type retaining wall adopting a spigot-and-socket prefabricating and assembling process. The cantilever-type retaining wall is characterized in that the cantilever-type retaining wall is divided into retaining wall segments with the length being 3.0-8.0 m in the road traveling direction, each retaining wall segment comprises a prefabricated face plate and a prefabricated bottom plate, tenons are arranged at the bottoms of the prefabricated face plates, and inserting grooves matched with the tenons are formed in the tops of the prefabricated bottom plates; andthe prefabricated bottom plates are placed on a cushion layer, mortar bedding materials are constructed at the parts, making contact with the face plates, of the prefabricated bottom plates, then thetenons at the bottoms of the prefabricated face plates are inserted into the reserved inserting grooves of the prefabricated bottom plates, thus the prefabricated face plates and the prefabricated bottom plates are connected,
