Embedded reinforced concrete arch bridge assembled by two oval arch pieces
The invention discloses an embedded reinforced concrete arch bridge assembled by two oval arch pieces. The embedded reinforced concrete arch bridge comprises a precast reinforced concrete arch body, precast reinforced concrete bases and precast reinforced concrete end walls, wherein subgrade filling soil is piled at the upper part of the precast reinforced concrete arch body and is pressed compact, the precast reinforced concrete arch body is an arch-shaped structure formed by connecting two oval arch pieces; when the two arch pieces are mounted, the relative longitudinal lateral sides are connected through a connecting beam, so that the two arch pieces are formed into a whole arch body; the other longitudinal lateral sides of the arch pieces are respectively supported by the precast reinforced concrete bases. Through the adoption of the embedded reinforced concrete arch bridge disclosed by the invention, the variety of middle-small span bridges is enriched; the internal force of the top of a beam body can be reduced; the sectional dimensions can be optimized; the upper load can be scattered onto the surrounding soil under the mutual effect of the beam body and soil, so that the self bearing force is improved, the stressed property is improved, and the construction cost is reduced; in addition, the components can be precast in factories, and can be mounted on the site, so that the construction period can be shortened, damage to the on-site construction environment is reduced, and the effects of low carbon and environmental protection are obvious.
