Embodiment Construction
[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0032] The present invention provides following technical scheme:
[0033] Such as Figure 1-4 As shown, a prefabricated reinforced soil retaining wall structure used for high-fill roadbeds includes soil roadbeds, geogrids 2 arranged in the soil roadbeds, and geogrids 2 arranged on both sides of the soil roadbeds and connected by connectors 7. The retaining wall 1 on both sides of the geogrid, the geogrid 2 is provided with several layers, and it is verticall...

The invention discloses a fabricated reinforced earth retaining wall structure for a high-fill highway roadbed, and relates to the technical field of retaining wall structures. The fabricated reinforced earth retaining wall structure comprises a soil roadbed, a geogrid arranged in the soil roadbed and a plurality of retaining walls arranged on the two sides of the soil roadbed and connected to the two sides of the geogrid through connecting pieces; an installation gap is reserved between every two adjacent retaining walls, retaining wall limiting pieces are installed in the installation gaps and connected with the side faces, close to each other, of the retaining walls in an attached mode, and supporting plates arranged in a trapezoid mode are fixed to the outer sides of the retaining wall limiting pieces. Each part of the structure can be prefabricated in a factory, so that construction period is greatly shortened, and the construction progress is guaranteed; meanwhile, a splicing structure is adopted during separation, so that the roadbed soil body can be effectively reinforced, lateral displacement of the soil body can be effectively limited, and meanwhile, construction of constructors is facilitated.
Description
technical field [0001] The invention relates to the technical field of retaining wall structures, in particular to an assembled reinforced soil retaining wall structure used for high-fill road subgrades. Background technique [0002] At present, there are two influences that should be paid attention to in the construction of high-fill road subgrade. One is to prevent road subgrade landslides; adverse effects on stability and durability. [0003] With the development of science and technology in the field of civil engineering, there are more and more roadbed slope reinforcement treatment processes. The invention aims at adopting geogrid embedded layer-by-layer reinforcement for the high-fill subgrade itself, and restricting the side slope of the subgrade by retaining walls. The retaining wall has the advantages of simple structure, convenient construction, local materials, obvious reinforcement effect, and strong adaptability, etc. Guarantee and later concrete maintenance ...
