AI Technical Summary

Problems solved by technology

However, the expansion device of the bridge is exposed to the atmosphere for a long time, and the operating environment is relatively harsh. It is the most vulnerable and difficult to repair part of the bridge structure.
The damage of the bridge expansion device may cause a large vehicle impact load, worsen the driving condition, and drastically reduce the service life and durability of the bridge.

Abstract

The invention discloses a steel-concrete combined structure monoblock type jointless bridge comprising a plurality of pairs of foundation piles, spanning structural steel girders matched with each pair of foundation piles, a concrete decking, a wiring pavement, an abutment rear filling layer, foundation piles, two abutments, and a plurality of first connectors. The steel-concrete combined structure monoblock type jointless bridge is simple in structure, good in force bearing performance, good in bearing capability and earthquake-proof performance, short in construction cycle, good in endurance, and telescoping apparatuses are cancelled.

Description

technical field [0001] The invention belongs to the technical field of bridge construction and relates to a steel-concrete combined structure integral seamless bridge. Background technique [0002] In modern road engineering, reinforced concrete / prestressed concrete bridges account for more than 90% of the total number of modern bridges due to their durability and economic advantages. However, in order to meet the deformation needs of the bridge structure under various effects and ensure that vehicles pass through the bridge deck smoothly, telescopic devices are usually arranged between the ends of the two girders, and between the ends of the girder and the abutment. However, the expansion device of the bridge is exposed to the atmosphere for a long time, and the operating environment is relatively harsh. It is the most vulnerable and difficult to repair part of the bridge structure. And the destruction of the bridge expansion device may cause a large vehicle impact load, w...
