林铭玉：生态袋防护措施在山区长输管道水工保护中的应用
生态袋防护措施在山区长输管道水工保护中的应用林铭玉
摘要：在山区开展长输管道水工保护工程施工时，传统的浆励石水保措施固受限于地形条件，石料运输十分不便，影响了水工保护工程施工进度。为了提高施工效率，借鉴其他行业以及同行业其他项目水工保护施工经验，采用生态袋水保措施替代浆砌石水保方案，经过三年多的试点研究，取得了显著的效果。生态袋防护结构能就地取土装袋施工，施工速度快，无需养护，能够快速实现管沟回填和地貌恢复，且固其能长出续植，可与周国环境融为一体，而具有一定的环保性。但它不适用于石方段，不宜用于河流库堤防护，生态袋挡土墙净高不宜超过4m，生态袋载水墙适用的管沟纵坡坡度为5°～30°

Application of the Ecological Bags Conservation Measure in Hydraulic Protection for
Long DistanceTransportation Pipelines in Mountain Areas LIN Mingyu
Abstract: The traditional mesonry water conservation medsure is limited by the topographic condition during the hydraulic protection construction of long distance pipelines in the mountain area, and it is inconvenient to transport building stones, which affecting the progress of hydraulic protection con struction. In order to improve the construction efficiency, and through drawing experiences of water conservation construction for other projects of the same or other industries, the masonry water conser vation measure is instead by the ecologicel bag measure. After more than three years of pilot research, aaeoa speed construction and no maintenance with using local solid and packing in place. It can quickly achieve the trench backfill and landform recovery. Green planting can grow from the bag, and then the bag can be integrated with surrounding environment, so it can protect environment. With certain applicable conditions, the ecological bag is unfit for the stonework place segment and river levee pro* tection. The retaining well height of ecological bags should not exceed 4 meters, and the longitudinal gradient of pipe trenches for the ecological bag cutoff wall is 5° ~30°

在山区开展长输管道施工时，为了防止雨水冲剧管道埋设坡面和管沟内回填土而造成水土流失，甚至管道外漏、断裂，常采用砌石、钢筋混凝土等硬性材料作为水工保护材料对坡面和管沟进行加固。但部分山区山高、林密、路少，石料运输十分不使，施工难度大、工期长、成本高，尤其沿海带台风频发，山区管道容易出现因水工保护不及时而造成水土流失问题。因此，为了更有效地治理水土流失和保障管道安全，海西天然气管网通过借鉴

行业其他项目生态袋水工保护施工经验，经过三年多的试点研究，总结了生态袋适用条件。
近年来，生态袋水工保护措施遂渐在石化行业以及其他行业应用，但对其适用条件研究基少，大部分只是对施工方法和方案进行论述"-。因生态袋强度会随时间变化，其耐久性和稳定性较传统的浆砌石水工保护措施低-，只有在合适的环境下使用，才能发挥它的优势，因此，有必要研究其适用条件。
