Anti-sinking bridge

Abstract

The invention discloses an anti-sinking bridge. The bridge comprises a bridgehead, a bridgehead connecting plate arranged on the bridgehead, a vehicle tripping prevention device connected with the bridgehead and the bridgehead connecting plate, a damping device arranged on the vehicle tripping prevention device, a bridge pier arranged in front of the bridgehead, a bearing table fixedly connected with the bridge pier, a compensation device arranged on the bearing table, a bridge plate arranged on the bearing table, lapping plates arranged on the two sides of the bridge plate, an external forcedredging device arranged in the bridge plate, and a limiting device arranged below the lapping plates. The vehicle tripping prevention device is arranged on the bridgehead connecting plate, so that adjustability of connection of the bridgehead and the bridge plate is realized, and the phenomenon of vehicle tripping of the bridgehead caused by natural settlement of a bridge is effectively prevented; and the external force dredging device is arranged, longitudinal loads borne by the single pier are dispersed through a mechanical means, concentrated loads are dispersed into local loads, and bridge sinking caused by passing of automobiles is reduced.

Description

technical field [0001] The invention belongs to the technical field of bridge construction, and in particular relates to an anti-subsidence bridge. Background technique [0002] As an important project in infrastructure construction, bridges play an irreplaceable role in geological environments such as crossing mountains, crossing seas, and crossing rivers. With the advancement of science and technology, people have gradually higher requirements for bridges, and their understanding of bridge construction has gradually become clearer; people gradually understand that after bridges are completed and put into use, as the number of years increases, bridge deck cracks or even fractures will appear in some parts of the bridge , affecting traffic, engineering is called bridge foundation settlement, there are two main factors causing bridge foundation settlement, the first is natural settlement, which is related to natural factors such as geological activities, groundwater and soil ...

[0002] As an important project in infrastructure construction, bridges play an irreplaceable role in geological environments such as crossing mountains, crossing seas, and crossing rivers. With the advancement of science and technology, people have gradually higher requirements for bridges, and their understanding of bridge construction has gradually become clearer; people gradually understand that after bridges are completed and put into use, as the number of years increases, bridge deck cracks or even fractures will appear in some parts of the bridge There are two main factors causing bridge foundation settlement. The first is natural settlement, which is related to natural factors such as geological activities, groundwater and soil loss, and cannot be avoided. This kind of settlement is not a short-term process, but a long-term change process, usually in decades; the second is to use settlement. After the bridge passes through, the vehicle will drive on it, which will give the pier 5 a short longitudinal Load, improper handling will cause subsidence of foundation soil
