Embodiment Construction

[0015] Such as figure 2 , image 3 Shown: the sunken ladder-type storage riverbed and river channel, using the natural slope of the river channel, without changing the original cross-sectional area of ​​the river channel and the flood discharge runoff, build a sunken ladder-type storage river water area 2 on the river channel; Every level of sunken ladder river bed 6 in the downstream is lower than the reservoir river bed of its upstream; build sunken ladder river dam 5 on the cross-section of sunken ladder type on the river course; A sunken stepped river bed 6 is formed between the stepped river dams 5, and a sunken stepped river embankment 3 is built at the original river bed 4 position of the river course; a layered water storage river area is formed; a natural pebble layer 7 is formed under the river bed and under the ground. see figure 1 , carry out comprehensive development and utilization in each storage river water area 2, plant trees and afforestation in areas such...

Abstract

The present invention relates to water conservancy engineering, especially the tackling of seasonal riberbed and river course. The present invention is characterized by that subsiding stepped water accumulating river with subsiding dams is constructed without changing the cross section area and flood discharging runoff and the water accumulating riverbed is lowered gradually from the upstream to the downstream. The stepped water accumulating riverbed makes it possible to utilize water comprehensively for beautifying environment, preventing riverbed desertification, regulating air humidity, maintaining ecological balance and safety discharge flood.

Description

(1) Technical field [0001] The invention relates to the field of water conservancy control engineering, in particular to the field of control engineering for seasonal regulation and storage of river beds and river courses. (2) Background technology [0002] Seasonal regulation and storage of riverbeds and channels are usually dry rivers with dry flow or small flow due to the influence of geographical conditions. It has a large natural slope. Due to the long-term influence of seasons and climate, the upstream water resources are insufficient, mainly due to the exposed It is formed by the accumulation of gravel, pebbles and sandy riverbeds. Especially in the urban cross-border section, the seasonal regulation and storage of riverbeds and river courses is more representative. In the dry season, not only the water is dry, the river is dry, and the desertification is serious, but also the waste and garbage are poured into the river. In the existing technology, the treatment of s...
