Town-level river channel composite ecological revetment structure

Abstract

The invention belongs to a town-level river channelcomposite ecological revetment structure in the field of town-level river channel ecological revetment technology.According to the technical scheme,the ecological revetment structure comprises an inner slope, a perpendicular revetment, and an ecological slope, wherein theinner slope, theperpendicular revetment, and the ecological slope aresequentially arranged from bottom to top along the inner side of a river channel,the top elevation of the perpendicularrevetment is located ata designed normalwaterlevel of the river channel; the top elevation of the ecological slope is higher than the designed high water level of the river channel; the perpendicular revetment comprisesan upper wall body and a lower bottomplate connected with the bottom end of the upper wall body, and the upper wall body is anet cage filled with bricks; a wetland is arranged on the ecological slope, water purification plants are planted on the wetland, a drainage channel is arranged at the slope top of the ecological slope, and sewage of the drainage channel is discharged into the wetland. The town-level river channelcomposite ecological revetment structureis simple and economic in structure, wide in application range, and convenient to construct, and the functional requirements of ecology, flood control, and sewage interception are met.

Description

technical field [0001] The invention relates to the technical field of town and village-level river ecological revetment, and relates to an ecological revetment structure. Background technique [0002] Town and village-level rivers refer to rivers in rural areas, and the surrounding areas are generally agricultural production land or rural construction land. The plane shape of such rivers is basically fixed. Ecological protection and restoration, maintenance and improvement of water quality, restoration and construction of river ecological landscape, to improve the ecological service function of the river. There are three main types of river section: rectangular section, trapezoidal section and compound section, and the corresponding three bank revetment forms are vertical, slope and composite. Composite revetment is a form of river section with limited land use, that is, the revetment includes both the inclined section and the vertical section, and is in the shape of steps...

Problems solved by technology

[0005] 2) The filling material in the gabion is pebbles or block stones; the cost is high, and once the metal mesh outside the gabion is damaged, the pebbles or block stones will collapse in bulk

[0006] 3) The foundation of the gabion cage is a cast-in-place reinforced concrete structure, which brings inconvenience to construction
