“长江一、二级堤防和重点堤防的穿堤建筑物、基础加固和防渗处理,抛石固基等施工难度大、技术要求高的工程”是由国家财政拨款的重点工程。水下抛柴枕施工近年来在长江重要堤防隐蔽工程中应用较为广泛,对堤防的压堤护岸起到了不可忽视的作用,而现有水利水电工程定额中缺乏与之相对应的定额。为此,以石首河湾整治工程送江码头段护岸工程为例,对水下抛柴枕的实际施工工艺及相应实测定额水平进行分析测算,以供同类项目施工参考借鉴。
“The project of embankment construction of the first and second grade embankments and key embankments of the Yangtze River, the construction of foundation reinforcement and seepage control, and the construction of solid foundation rubbings with high technical requirements” are key projects funded by the state finance. In recent years, the construction of underwater throwing firewood sleepers has been widely used in the concealment projects of the major embankments of the Yangtze River and played a significant role in embankment embankment protection and bank revetment. However, there is a lack of corresponding quotas for the existing hydropower projects. Therefore, taking Shishou Bay Regulation Project as example, the actual construction technology of underwater throwing Chaihu and the corresponding actual measurement quotas are analyzed and calculated for the reference of similar projects.
