A cross-sectional structure of river channel for alleviating the tension of urban land use

Abstract

The invention relates to a river section structure for relieving urban land tension. The river section structure consists of a rectangular section, a water accessibility bank slope and a land territory control ground in sequence, wherein the rectangular section consists of a natural river bottom and a dry stone upright wall; the water accessibility bank slope consists of a water accessibility platform and an ecological side slope; the land territory control ground is positioned above the water accessibility bank slope. The river section structure is characterized in that the land territory control ground rises no less than a planned safe free board in the outward longitudinal direction, and the rise value is 0.5-1 meter. By designing the land territory control ground with the safe free board, the blue-line land territory control range can be fully utilized. By adopting a rectangular section structure on a main river channel, land is saved, the safety is ensured, and various functions of the river channel are not weakened, thereby eliminating the contradiction between urban land development and water.

Description

technical field [0001] The invention belongs to the technical field of urban river ecological protection, and in particular relates to a river cross-section structure for alleviating urban land tension. Background technique [0002] With the rapid development of urbanization and industrialization in our country, the land for urban development and industrial construction is increasingly tight. At the same time, the new development puts forward higher requirements for the safety, ecology, beauty and harmony of human and water of the river. Paying attention to the safety, ecology, and landscape maintenance of urban rivers will require more space for rivers, but this forms a pair of sharp contradictions with improving urban land utilization. Usually, on the premise of ensuring flood control safety, competing with water for land and sacrificing the ecological environment and landscape have become the norm. For example, in the general channel section, the main channel mostly adop...

AI Technical Summary

Problems solved by technology

For example, in general river sections, the main channel mostly adopts a trapezoidal section, and the safety superelevation is set together with the slope protection, and slopes upward along the slope protection, followed by the land area control area, which wastes a lot of precious land in areas with tight land use.
