Deep pool and shoal for improving ecological environment of river channel and deep pool and shoal construction method thereof

Abstract

The invention relates to the technical field of riverway construction, in particular to a deep pool and shoal for improving the ecological environment of a riverway and a deep pool and shoal construction method thereof.The deep pool and shoal construction method comprises the riverway, a shoal and a deep pool are arranged in the riverway, a shoal generation device and a deep pool generation device are arranged on the two sides of the riverway, and a connecting component is arranged on one side of the shoal generation device; the shoal generating device and the deep pool generating device are arranged on the river channel, so that an accumulation part is arranged on the front side of the shoal generating device, and a guide plate is arranged on the upper side of the shoal generating device, and sediment flowing at the bottom of the river is in contact with the guide plate; the sediment can move downwards to be gathered and can be prevented from being washed away by water flow, the effect that the sediment is accumulated at a fixed position is achieved, then after the shoal generating device is moved away, the accumulated sediment can form a shoal, the water flow speed is increased, paving of the gravels at the river bottom is matched with the water flow, water jump can be generated in the water body, and the oxygen content of the water body is increased.

Description

technical field [0001] The invention relates to the technical field of channel construction, in particular to a deep pool shoal for improving the ecological environment of a river channel and a construction method for the deep pool shoal. Background technique [0002] In river landforms, the raised areas in the river bed can be called shoals, and the sunken areas can be called deep pools. Deep pools and shoals are the most common habitat structure types in river landforms. Deep pools and shoals exist alternately in natural rivers. In the shoal habitat, the water flow is turbulent, which is conducive to the aeration and oxygenation of the river water body; the deep pool habitat Among them, the water flow is slow, and it is the main place for fish and various molluscs to rest and take refuge. Their interactive existence can consume the energy of the water flow and keep the river bed stable. [0003] However, most of the existing shallow and deep pool construction equipment ar...

AI Technical Summary

Problems solved by technology

[0003] However, most of the existing shoal and deep pool construction equipment are disposable, and need to be designed separately according to the shape of the river, which greatly reduces the versatility and greatly increases the construction cost of shoals and deep pools
