Construction method of ecological re-greening of high-steep side slope of river channel

Abstract

The invention discloses a construction method of ecological re-greening of a high-steep side slope of a river channel. The construction method includes the following steps that (1) inspection and danger removal operation are conducted on the slope surface, and unstable geological hidden troubles need to be first stabilized during being found; (2) a plurality of semi-arc type rigid micro-platformsare laid horizontally and uniformly at the top of the slope surface, and are used for dividing the slope surface horizontally; (3) the lower parts of the semi-arc type rigid micro-platforms are lockedand supported through semi-arc type anchor rod combining wall clamps; (4) flexible polypropylene long fiber rods are horizontally laid in arc-shaped grooves of the semi-arc type rigid micro-platforms, and the staggered survival rate of a vegetation root system staggered network is increased; (5) three-dimensional vegetation bodies are paved with the intervals of the micro-semi-arc type rigid micro-platforms and locked with anchor rods; and (6) the whole slope is swept and sprayed with seed layers through a vehicle-mounted spray-seeding vehicle. According to the construction method of ecological re-greening of the high-steep side slope of the river channel, the construction time is short, rapid beautification of the surrounding environment can be achieved, the effect of urban landscape isimproved, and remarkable economic and ecological benefits are achieved.

Description

technical field [0001] The invention relates to the technical field of ecological restoration of river slopes, in particular to a construction method for ecological restoration of high and steep river slopes. Background technique [0002] The ecological regreening project of high and steep river slopes is an engineering measure taken to protect river embankments from erosion and erosion by water flow, wind and waves. At present, the treatment methods for treating high and steep river slopes in China are mainly based on slurry-cut stone retaining walls, gabions, stacking of ecological bags and stacking masonry. These traditional governance structures are effective in maintaining the structure of river slopes It plays a certain role in stability, prevention of soil erosion and flood control, but it does not play a role in river ecology, environmental protection, urban landscape, etc., and cannot meet the regreening requirements.

Problems solved by technology

At present, the treatment methods for treating high and steep river slopes in China are mainly based on slurry-cut stone retaining walls, gabions, stacking of ecological bags and stacking masonry. These traditional governance structures are effective in maintaining the structure of river slopes It plays a certain role in stability, prevention of soil erosion and flood control, but it does not play a role in river ecology, environmental protection, urban landscape, etc., and cannot meet the regreening requirements

[0003] At present, the most important factors to be considered for the ecological restoration of high and steep river slopes are safety and stability. The specific structural forms are mostly: slurry cut stone retaining wall, gabion, stacking of ecological bags and stacked masonry, etc., among which Slurry-cut block stone retaining walls cannot meet the ecological restoration landscape effect; gabion, ecological bag stacking and stacked masonry are only used in areas with gentle slopes, wide rivers, and slow-flowing rivers, and are applied at 70° or above , prone to slope collapse, slippage, etc., the effect on ecological restoration of high and steep river slopes is not very significant
