The present invention also relates to a construction method of the flood control traffic gate structure for a sloping road along a river in an urban area. Background Art
[0002] Against the backdrop of climate change, extreme weather events are occurring frequently, and the pressure on urban flood control is increasing. Urban flood walls, as basic engineering facilities for urban flood control, play a core role in defending against floods and protecting cities and residents from the harm of water disasters. At the same time, embankment projects, as an important part of public infrastructure, are increasingly receiving attention and attention for their ecological function value.
[0003] During the design and construction of urban flood walls, to ensure the closed flood control circle and avoid the occupation of restricted basic farmland, the embankment line must sometimes cross existing riverside roads. Riverside roads have a certain longitudinal slope when passing through bridges and other structures. Temporary blocking measures to address gaps in the road during flood season are labor-intensive and inefficient. They cannot guarantee the safety of the closed flood control circle at high design flood levels. The installation of permanent works is prone to sudden changes in ground elevation at road junctions, causing vehicles to jump out of the road, impacting driving experience and traffic safety.
[0004] Therefore, it is of great significance to study a traffic gate structure and its construction method that can be well connected with the main structure of the urban flood control wall, take into account the closure of the flood control circle and normal traffic along the river in the non-flood season, and avoid the phenomenon of vehicle jumping in the slope section.
