生态护坡在河道治污工程中的应用

以霞湾港治污工程为例,根据不同河段的流速及污染程度分别设计使用了雷诺护垫护坡和空心混凝土六角块护坡。雷诺护垫生态护坡属引进产品,主要应用在霞湾港污染较轻、坡降较陡、流速大的上游段。空心混凝土六角块护坡是混凝土六角块护坡的改进型,主要应用在流速小、污染较重的霞湾港出口段,一方面利用植被网的固土保土功能,可有效防止表面土层的滑移,提高迎水坡面的整体性,另一方面利用六角块良好的力学性能,可增加不稳定坡面的整体性,为绿化创造有利条件。

Application of Ecological Slope Protection in Channel Pollution Control

Taking channel pollution control project in Xiawan Harbor as example,Reynolds mat and hexagonal hollow concrete block were designed for slope protection according to flow velocity and pollution degree in different channel reaches.Ecological Reynolds mat is an introduced product for slope protection,and mainly applied in upper reaches of Xiawan Harbor where pollution is slight but flow velocity resulting from steep slope is high.Hexagonal hollow concrete block is an improved hexagonal concrete slope protective block,and mainly applied in outlet of Xiawan Harbor where flow velocity is slow but pollution is relatively serious.Soil conservation function of vegetable net was used to prevent surface soil from sliding,it also could raise entirety of water-fronting slope.And on the other hand,mechanics of hexagon block could be used to increase entirety of unstable slope,and to create advantage condition for slope greening.
