Abstract

The invention discloses an FRP (fiber reinforce plastic) tube concrete and FRP corrugated plate combined buried arch bridge and a construction method thereof, wherein the combined buried arch bridge comprises a plurality of rows of longitudinally arranged arch rings, a concrete foundation and roadbed filling soils; both ends of the arch rings are respectively fixed in the concrete foundation located at the both ends of the arch bridge; horizontally arranged bed boards are laid on the surface of the arched rings; the roadbed filling soils are stacked on the bed boards and are compacted. The FRP tube concrete and FRP corrugated plate combined buried arch bridge disclosed by the invention has the characteristics of reasonable structure, good durability, simple and convenient construction, economical efficiency and environmental protection.

Description

technical field [0001] The invention relates to the field of highway municipal technology, in particular to an embedded arch bridge combined with FRP pipe concrete and FRP corrugated plates and a construction method thereof. Background technique [0002] FRP (Fibre Reinforced Polymer / Plastics) is composed of continuous fiber and resin matrix. Commonly used fibers include carbon fiber, glass fiber and aramid fiber, and commonly used resins include epoxy resin, polyester resin and vinyl ester resin. According to the type of fiber, FRP materials can be divided into three categories: glass FRP materials (GFRP), carbon FRP materials (CFRP), and aramid FRP materials (AFRP). [0003] The research on FRP materials first appeared in Switzerland in the 1980s as a reinforcement, reinforcement and repair technology for reinforced concrete structures, and then developed rapidly in developed countries such as Japan, the United States, and Europe in the 1990s. Use FRP norms and standards...
