Abstract

The invention discloses an anti-settling plate device for a widening bridge joint. The device comprises an ultrahigh-toughness reinforced concrete anti-settling plate and tensile anchoring steel bars,the ultrahigh-toughness reinforced concrete anti-settling plate is arranged above a joint of the newly-built bridge and the old bridge; one end of the high-toughness reinforced concrete anti-settlingplate is hinged to the old bridge through the tensile anchoring steel bars, the other end of the high-toughness reinforced concrete anti-settling plate is placed on the newly-built bridge, bridge floor cast-in-place layers are laid on the old bridge and the newly-built bridge, and the two ends of the ultrahigh-toughness reinforced concrete anti-settling plate are connected with the bridge floor cast-in-place layers on the two sides respectively. According to the method, longitudinal cracks, caused by settlement deformation of the newly-built bridge, of the asphalt pavement layer can be effectively avoided, the durability of joints of the spliced wide bridge can be improved, and the driving comfort of the spliced wide bridge is greatly improved.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to an anti-settling plate device for spliced ​​wide bridge joints. Background technique [0002] With the rapid development of my country's social economy, there are more and more reconstruction and expansion projects of urban roads, national and provincial trunk roads, and rural roads. The design of the widening bridge should not only consider the new bridge itself, but also consider the utilization and impact of the existing old bridge, the overall requirements after widening, and the impact on traffic comfort. Due to the asynchronous settlement of the new bridge and the old bridge, the traditional bridge joints are prone to longitudinal cracks and diseases at the asphalt pavement at the joint. And with the rapid development of the domestic economy, the people's requirements for the driving comfort and durability of the bridge structure are also getting higher an...
