Problems solved by technology

Although this method increases the counterweight of the foot of the embankment, under low flow, the water flow is narrowed into a nearly straight line and flows in the middle of the riverbed, and the landscape is monotonous in low water. If the gap is too large, it has no function of filtering and purifying the water body, so its ecological landscape effect is poor

Embodiment Construction

[0021] Such as Figure 1-Figure 3 The shown staggered-foot beam-shaped ecological river course between the tidal river sections includes a river channel body surrounded by embankments 1 on both sides, and a number of riprap foot piles 2 are arranged on the river channel body, and each riprap foot pile 2 is along the embankment. 1 The direction is staggered, so that an "S"-shaped river channel is formed in the river itself. Different from the traditional continuous strip riprap presser foot, the riprap presser foot stack 2 of this embodiment is arranged in a staggered manner, and the riprap presser foot stack 2 is disconnected along the embankment 1 direction, and the length of the arrangement along the embankment 1 direction is about The height of embankment 1 is 0.5 to 2 times, and the distance between riprap foot piles 2 adjacent to embankment 1 on the same side is about 1.5 to 3 times the height of embankment 1; the height of riprap foot pile 2 is set to be slightly lower t...

Abstract

The invention relates to a tidal reach staggered-press-foot narrowed ecological river course. The tidal reach staggered-press-foot narrowed ecological river course comprises a river course body defined by banks on the two sides, a plurality of riprap press foot piles are arranged on the river course body, and all the riprap press foot piles are arranged in a staggered mode in the direction of the banks, so that an S-shaped river channel is formed in the river course body. Through the riprap press foot piles arranged in the river course body in the staggered mode, the river channel can be narrowed to be shaped like S under working conditions of small flow, specially under working conditions of tidal reaches and reversing currents, the flow velocity and the water depth of the river channel are increased, the water flow forms are enriched, a more diversified bank foot animal and plant habitat is provided, and the ecological landscape effect of the river course is improved. The tidal reach staggered-press-foot narrowed ecological river course can be applied to rive improvement under working conditions of small flow.

Description

technical field [0001] The invention relates to river regulation, in particular to a staggered-foot beam-shaped ecological river course between tidal river sections under the condition of small flow. Background technique [0002] The presser foot is an important measure to prevent the foot of the embankment from being scoured and to ensure the safety of the embankment in the design of river regulation. At present, the known presser foot is the riprap presser foot, also known as the riprap foot presser belt, which is distributed in a strip shape along the embankment foot. The riprap presser belt is divided into two basic forms: flat river bed and high river bed, each of which has its applicability and limitations. [0003] (1) Flat river bed riprap foot belt: the riprap surface is consistent with the river bed elevation, and the riprap is arranged in a continuous flat belt at the foot of the embankment. The size depends on the embankment conditions, usually with a thickness o...
