Description

Technical Field

[0001] The utility model relates to the field of bridge protection structures, in particular to a flood impact resistance structure of a water conservancy bridge. Background Art

[0002] Bridges generally refer to structures built across rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to buildings that cross mountain streams, poor geology, or meet other transportation needs to make passage more convenient. When a bridge encounters a flood, it may collapse, causing a large amount of economic losses and casualties. Therefore, it is necessary to install flood-resistant structures on the bridge.

The utility model is fixedly installed with a fixing plate on the left and right sides of the column, and the guide rod is fixedly connected with the baffle through the guide groove provided in the fixing plate, and the column is vertically placed on the front side of the dam body. When the flood impacts the dam body, the baffle can be pushed to move backward to squeeze the spring, and the elastic force of the spring can resist a part of the impact force of the flood, thereby playing a protective role. After the flood recedes, the spring can automatically recover and push the baffle to reset. The structure is simple, the cost is low, and it is suitable for wide promotion.

[0005] With respect to the above and existing related technologies, the inventor believes that there are often the following defects:
