Description

Assembled buttress type retaining wall Technical Field The utility model relates to the technical field of buttress retaining walls, in particular to an assembled buttress retaining wall. Background The retaining wall is widely applied to engineering fields such as bridges, tunnels, roads, water conservancy projects and the like as an important geotechnical structure. The retaining wall is divided according to materials, and comprises stone retaining walls, concrete retaining walls and reinforced concrete retaining walls. The retaining wall is classified according to structural form, and may be classified into a gravity type retaining wall, a cantilever type retaining wall, a buttress type retaining wall, an empty box type retaining wall, etc. The differences in the structural form of the retaining wall determine its mechanical properties and engineering flexibility. The wall-supporting retaining wall forms a space supporting system by additionally arranging the longitudinal reinforcing rib plates (the supporting walls), so that the cooperative bearing capacity of the wall body and the foundation plate can be effectively enhanced, and the stress distribution state of the whole structure is obviously improved. However, in the construction of the buttress retaining wall, in order to maintain the stability and bearing capacity of the retaining wall, a large number of templates are usually required to be supported in a designated area for concrete cast-in-situ, the construction speed is slow, and a relatively thick casting space is usually required to be reserved when the templates are supported so as to ensure the thickness of the retaining wall and the bearing capacity of the retaining wall, so that the integrity of the retaining wall is improved, and a large number of casting materials are required. Disclosure of utility model The utility model aims to provide an assembled buttress retaining wall, which is based on the overall stability; The utility model provides an assembled buttress retaining wall which comprises a bottom plate, wherein a plurality of rows of cavity panel modules are arranged on the bottom plate side by side, buttress modules are arranged at the joint of every two rows of cavity panel modules, each row of cavity panel modules comprises a plurality of wall panels spliced along the height direction, each group of buttress modules comprises a buttress base and a plurality of buttress ribs, penetrating reinforcing steel bars respectively used for penetrating the cavity panel modules and the buttress modules are embedded in the bottom plate, reinforcing steel bar cages are embedded between every two adjacent groups of cavity panel modules corresponding to the bottom plate, and each wall panel is provided with a cavity.
