为什么现在的水利工程都要用生态护坡呢?
Why do water conservancy projects need ecological slope protection?
1、生态护坡技术的植物能与周围的植物和谐共生,来实现物种之间的平衡,同时还可以为河道周围的动物提供一些生活的场所和食物等。因此采用生态护坡施工技术能够充分的保护河道周围的环境。
1. The plants of ecological slope protection technology can coexist harmoniously with the surrounding plants to achieve the balance between species, and provide some living places and food for animals around the river. Therefore, the ecological slope protection construction technology can fully protect the environment around the river.
2、平铺护坡技术能够使水流内的具体情况跟随水域的不同进行调整。还可以在洪水来临的时候,生态护坡技术上的丰富的植被,能够抵御一定洪水的侵蚀;同时在气温较高时,护坡上的植被还能将自己的水分释放放到河道中,缓解河流的干旱情况。因此,水利工程中的河道生态护坡施工技术能够有效的抵挡洪水以及耐旱的作用。
2. The technology of slope protection can adjust the specific situation of water flow according to the different water area. In addition, when the flood comes, the rich vegetation in ecological slope protection technology can resist the erosion of certain flood; at the same time, when the temperature is high, the vegetation on the slope protection can release its own water into the river to alleviate the drought situation of the river. Therefore, the water conservancy project can effectively resist the flood and protect the slope.
3、平铺护坡生态框施工技术在一定程度上,可以将周围的环境变得更加美丽、生态。
3. To a certain extent, the construction technology of ecological frame for slope protection can make the surrounding environment more beautiful and ecological.
生态阶梯护坡的特点:1.固土效果好。2.冲刷能力强。3.经济环保。4材料轻、耐磨损、韧性好、冲击力强、运输方便。5施工方法方便,并可多次利用。
The characteristics of ecological step slope protection are as follows: 1. 2. Strong scouring capacity. 3. Economic and environmental protection. 4. Light material, wear resistance, good toughness, strong impact force and convenient transportation. 5. The construction method is convenient and can be used for many times.
防止水土流失:能降低坡体孔隙水压力、截留降雨、削弱溅蚀、控制土粒流失;改善环境功能:植被能恢复被破坏的生态环境,促进有机污染物的降解,净化空气,调节小气候。主要应用于水流条件平缓的中小河流和湖泊港湾处。固土植物一般应选择耐酸碱性、耐高温干旱,同时应具有根系发达、生长快、绿期长、成活率高、价格经济、管理粗放的特点。
Prevention of soil erosion: it can reduce the pore water pressure of slope, intercept rainfall, weaken splash erosion and control soil particle loss; improve environmental function: vegetation can restore the damaged ecological environment, promote the degradation of organic pollutants, purify the air, and regulate the microclimate. It is mainly used in small and medium-sized rivers and lakes with gentle flow conditions. Soil fixing plants should generally be acid and alkaline resistant, high temperature and drought resistant, and should have the characteristics of developed root system, fast growth, long green period, high survival rate, economic price and extensive management.
