Abstract

The invention relates to a method for constructing a deep pool shoal in a slow-flow riverway. The method comprises the following steps that 1, spur dikes are symmetrically arranged the positions nearbanks on the two sides of the riverway; 2, the shoal is arranged between the two spur dikes, and the flow surface of the shoal is of a V-shaped structure, the low end is located in the center, the high ends are located on the two sides, and the high ends are lower than the upper surfaces of the spur dikes, and the space defined by the two sides of the shoal and the spur dikes and the banks is a deep pool. 3, an upstream slope and a downstream slope are arranged on the two sides of the shoal flow surface respectively, the slope of the upstream slope is larger than that of the upstream slope, water flow in the riverway passes through the deep pool, the upstream slope, the shallow flow surface and the downstream slope in sequence. According to the method, the spur dikes and the shoal are usedfor constructing the deep pool shoal in the riverway, the structure is simple, the self-purification capacity of river water can be improved, and the biodiversity in the riverway is increased.

Description

technical field [0001] The invention relates to a method for constructing deep pools and shoals in slow-flowing river courses, and belongs to the technical field of river ecological restoration. Background technique [0002] With the development of urbanization, the pollution of the slow-flowing tributary rivers that shuttle between cities is becoming more and more serious, resulting in a decline in water quality and biodiversity in tributary rivers, and even turning into black and smelly water bodies. When it is discharged into the main river of the city When it is not enough to purify completely, the main river channel will be polluted, causing a vicious circle. In the long run, it will only cause serious damage to the river course in the urban area. As people's awareness of environmental protection increases, we need to use ecological methods to deal with rivers and improve the ecological health of rivers. [0003] The flow velocity in slow-flowing rivers is slow, so th...
