Embodiment Construction

[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0034] like Figure 1-4 As shown, the present invention provides a multi-category combined ecological hydraulic system that is beneficial to the heterogeneity of geomorphic units in the river channel, including the channel bottom geomorphic unit component 3 laid on the bottom of the river channel, embedded in the bottom of the concave bank of the river channel The deep pool geomorphic unit component 1 and the shoal geomorphic unit component 2 half-buried at the inflection point of the curved river section; the channel bottom geomorphic unit component 3 is a flat rhombic quadrangular prism plate-shaped structure and is arranged along the length direction of the channel. A plurality of circular holes are evenly distributed on its upper surface and a plurality of diamond-shaped protrusions are fixed between the circular holes, and the ci...

Abstract

The invention discloses a multi-category combined ecological hydraulic system and a construction method thereof. The system includes a channel bottom geomorphic unit component laid on the bottom of a river channel, a deep pool geomorphic unit component embedded in the bottom of the concave bank of the river bed, and a half-buried The shoal geomorphological unit component placed at the inflection point of the curved river section of the river channel; the channel bottom geomorphic unit component is a flat rhombus quadrangular prism, with a number of circular holes evenly distributed on its upper surface and a number of diamond-shaped protrusions fixed The deep pool landform unit components include a cube-shaped frame and a plurality of multi-lobed arc tubular members embedded in the frame; The circular tubular member; the interior of the arc tubular member and the circular tubular member is hollow, and a plurality of circular permeable holes are evenly distributed on the surface. This system can promote the plane meandering shape of the channelized channel and the development of landform units.

Description

technical field [0001] The invention relates to the technical field of ecological river channel construction, in particular to a multi-category combined ecological hydraulic system and a construction method thereof which is beneficial to the heterogeneity of landform units in the channel. Background technique [0002] The biodiversity of natural rivers is positively correlated with the spatial heterogeneity of rivers. The higher the spatial heterogeneity of habitats, the more diverse the biological habitats, and the corresponding increase in biodiversity. The river course improvement for the purpose of flood control transforms the meandering natural river into a straight line and hardens the river bed material. This transformation changes the pattern of rapids and slow flows, deep pools and shoals, resulting in different habitats. Qualitative reduction, changes in the living environment of benthic organisms, and reduction in biodiversity are not conducive to the construction...
