Description

Modularized precast concrete retaining wall structure Technical Field The utility model relates to the technical field of highway engineering and ecological protection, in particular to a modularized precast concrete retaining wall structure. Background The retaining wall is used as a core retaining structure, is widely applied to the scenes such as slope stability protection, terrain slope collection, land-limited road section improvement and the like, and has the core functions of balancing the lateral pressure of soil bodies, preventing the rock-soil bodies from unstably collapsing and optimizing the line-type layout of roads. There are various types of retaining wall structures available, which have significant differences in material characteristics, construction efficiency, and environmental suitability. The gravity type retaining wall constructed by masonry or concrete has the characteristics of simple structure and stable anti-overturning by means of self weight of the structure, but has the advantages of overlarge resource consumption, large section size, high concrete consumption, large natural stone blocks needing to be mined and easy non-renewable resource waste. The method has the advantages of easy environmental pollution caused by in-situ wet casting, long construction period, small allowable non-uniform settlement of the foundation and easy generation of structural cracks in soft foundation areas. The gabion retaining wall formed by the steel wire net box and the rock block filler has the advantages of good water permeability and convenient construction, but the steel wire net is exposed in natural environment for a long time, so that the strength is easy to be attenuated due to corrosion, the particle size of the material becomes small after weathering and disintegration, and the filler is lost when the particle size is smaller than the mesh size. Disclosure of utility model The utility model aims to provide a modularized precast concrete retaining wall structure which has the advantages of high structural durability, energy conservation, environmental protection, contribution to improving construction efficiency and ecological environmental protection. To achieve the purpose, the utility model adopts the following technical scheme: There is provided a modular precast concrete retaining wall structure comprising: The cast-in-situ foundation is arranged at one side of the embankment, and the upper end face of the cast-in-situ foundation is inclined along one side close to the embankment; The backstop subassembly, set up in cast-in-situ basis's up end, the backstop subassembly includes: The prefabricated box body is propped against the embankment, the prefabricated box body is provided with a containing cavity, and the containing cavity is provided with a filler; The precast concrete wedges are inserted into the accommodating cavity and are abutted against the adjacent precast box bodies.
