Half-through bowstring arch bridge with vehicle and light rail on same layer and construction method thereof

Abstract

The invention relates to a half-through bowstring arch bridge with a vehicle and a light rail on the same layer. A main beam of the arch bridge adopts a mixed structure; a side span main beam adopts a prestressed concrete structure; and a mid-span main beam adopts a steel box girder structure. The arch bridge is characterized by having a combined arch force transfer system; and the force transfer system comprises a lifting basket type steel box main arch and a back stay rope. As a novel structural design of a bridge building is adopted, the same-layer arrangement of improving the linear technology standard and reducing the manufacturing cost is realized, and the beauty and structure unification of the bridge building is realized.

Description

Technical field [0001] The present invention involves a medium -ending rod arch bridge and its construction method of the same layer of automobiles and light rails, especially the way the bridge involves the new type of medium -sized inheritance of car loads, light rail loads, and the cancellation of columns.Tie arched bridge bridge system. Background technique [0002] Bridge is a way to provide transportation to cross -obstacles. When serving different transportation, various bridges form various bridges: highway bridges, municipal bridges, railway bridges and two or three types of common bridges.Highways and railway coexisting bridges, municipal and light rails, etc. The layout methods taken by different transportation on the bridge are mainly arranged on the main beam and lower layer of the steel truss.Due to the restrictions of the lower layer and its building height, the vertical surface of the upper layer setting up is too large, resulting in too long bridges and high cost...

AI Technical Summary

Problems solved by technology

Due to the limitation of the clearance of the lower floor and its building height, the longitudinal section of the route laid on the upper floor is raised too much, resulting in too long approach bridge and high cost. At the same time, the structure at the separation of the upper and lower floors is difficult to handle, and the landscape is poor. If the separation is met again If the route crosses and is complicated, the traffic organization will be difficult and easily confused, and the cost of the cross project will also be high.
