Abstract

The invention discloses a fabricated UHPC pipe culvert structure, The structure comprises prefabricated pipe joints, a foundation bed is arranged below the prefabricated pipe joints, the outer side of a pipe joint joint between every two adjacent prefabricated pipe joints is wrapped by double-layer asphalt felt, the inner side of the pipe joint joint is plastered with cement mortar, and a middle gap is filled with asphalt hemp batting; tamping areas are arranged on the two sides of the prefabricated pipe joints and the two sides of the foundation bed; and the prefabricated pipe joints are made of a UHPC (Ultra High Performance Concrete) material. The structure design is reasonable, the high-strength performance of the UHPC material is fully played, the structure is of a pure concrete structure, the rebar positioning and binding procedure is omitted, and prefabrication is easy and convenient.

Description

technical field [0001] The invention relates to the technical field of culvert channel construction, in particular to an assembled UHPC pipe and culvert structure. Background technique [0002] Culvert structure is an important structure in road engineering. The main function is to vent surface water flow, or to facilitate the passage of people, livestock and vehicles. Culverts and passages have the characteristics of large number and wide distribution in the range of highways in our country, and their quality directly affects the stability of structures and driving safety. [0003] Traditional reinforced concrete pipe culverts and steel corrugated pipe culverts are widely used because of their simple structure and convenient construction, but their durability is poor in strong freeze-thaw and strong corrosion environments. UHPC materials have super durability and can be widely used in the above environments. Contents of the invention [0004] Aiming at the above-mentio...
