吉林引四平市天然气长输管道工程 ,虽占地面积不大 ,但因线路长、跨越地貌类型多、穿越道路与河流多 ,施工过程中对沿线地貌植被及耕地影响较大 ,易造成人为水土流失。为减少和防治水土流失 ,其主体工程的施工应避开雨季和风季 ,在管线穿越公路和河流的地段要采取浆砌石护坡或护岸 ,穿越耕地铺设地下管道时要处理好表土 ,在埋设管道的覆土上应种植浅根性植物 ,其他施工区和影响区应采取工程措施和植物措施进行综合治理。 Jilin Province leads the Siping City natural gas long-distance pipeline project, although covers an area not to be big, but because the line is long, crosses the landform type many, crosses the road and the river many, during the construction process has the greater influence to the landscape vegetation and arable land along the line, Loss. In order to reduce and control soil and water loss, the construction of the main project should avoid the rainy season and the windy season. Mudstone revetments or revetments should be adopted in the sections where the pipeline crosses the roads and rivers. When the underground pipelines are laid across the cultivated land, Of shallow soil should be planted on the soil, other construction areas and affected areas should take engineering measures and plant measures for comprehensive management.
