Technical Field
[0001] The utility model belongs to the technical field of road and bridge engineering, and particularly relates to a highway water retaining wall structure. Background Art
[0002] There are a large number of sections adjacent to rivers or ditches in highway projects. Generally, the design flood frequency is determined according to the technical grade of the highway, so that the design elevation of the highway is higher than the corresponding design flood level elevation of the adjacent river / ditch under the design flood frequency, in order to prevent the water flow in the adjacent river / ditch from rushing onto the highway and endangering the driving safety on the road surface.
[0003] The following problems exist in the actual construction process of highway projects:
[0004] First, due to the constraints of terrain or other factors in the newly built highway, it is impossible to increase the design elevation of the highway or lower the design flood level elevation, resulting in the local design elevation of the highway being lower than the design flood level elevation.
[0005] Second, the corresponding design flood level elevation increases due to the improvement of the grade of the reconstructed highway, making the original highway design elevation lower than the current design flood level elevation. If the design elevation of the highway is increased or the current design flood level elevation is lowered, the project quantity will be greatly increased and the project cost will be raised.
[0006] Third, although the design elevation of the highway is higher than the design flood level elevation, in case of heavy precipitation, the water level in the river / ditch will rise rapidly, and the water flow or backwater will rush onto the highway, thus endangering the driving safety on the road surface.
