Prefabricated ultra-high performance concrete honeycomb arch bridge structure and construction method thereof

Abstract

The invention provides a prefabricated ultra-high-performance concrete honeycomb arch bridge structure which comprises an arch piece unit, a rigid frame unit connected with the arch piece unit and a bridge deck unit laid on the surfaces of the arch piece unit and the rigid frame unit, and the arch piece unit and the rigid frame unit are prefabricated in a segmented mode through ultra-high-performance concrete materials. The bridge deck unit is prefabricated by common concrete or ultra-high performance concrete in sections, the arch piece unit, the rigid frame unit and the bridge deck unit are connected into a whole by filling the ultra-high performance concrete at wet joints, and the arch piece unit is provided with a plurality of holes. The prefabricated ultra-high performance concrete honeycomb arch bridge structure has the advantages of being light in self weight, small in sectional area, high in bearing capacity, capable of saving materials, easy to install, high in construction efficiency, safe, environmentally friendly, low in comprehensive manufacturing cost and the like. The invention further provides a construction method of the prefabricated ultra-high-performance concrete honeycomb arch bridge structure.

Description

technical field [0001] The invention relates to the technical field of bridge engineering, in particular to a prefabricated ultra-high performance concrete-ordinary concrete honeycomb arch bridge structure and a construction method thereof. Background technique [0002] Arch bridges have the advantages of simple structure, strong spanning ability, and good durability, and have a relatively long history of application in my country. The survey results on the operation status of arch bridges show that traditional reinforced concrete arch bridges or masonry arch bridges cannot be too small due to their relative bulkiness and high thrust. In addition, due to the cumbersome construction process and long construction period, the quality of arch bridges is also difficult. Warranty etc. At present, the use of steel arch bridges in long-span bridges has become a common trend, but there are also problems such as complex structures, high initial construction and installation costs, an...

Problems solved by technology

The survey results on the operation status of arch bridges show that traditional reinforced concrete arch bridges or masonry arch bridges cannot be too small due to their relative bulkiness and high thrust. In addition, due to the cumbersome construction process and long construction period, the quality of arch bridges is also difficult. Guarantee etc.

At present, the use of steel arch bridges in long-span bridges has become a common trend, but there are also problems such as complex structures, high initial construction and installation costs, and high later maintenance costs, which cannot effectively guarantee economic efficiency
