摘要
水力冲挖法是一种较为环保的土方开挖方法,具有效率高、噪声低、污染小的特点。由于水力冲挖法可灵活增加或改变管道长度和导向,对施工场地的大小和地质环境的依赖很小,近些年来在水库清淤、滩涂填筑等运输条件不便的大型场地类工程中得到了快速推广。文章就水力冲挖法在丰宁抽水蓄能电站下水库清淤工程中工艺原理、设备选型、管线设计等方面的应用经验进行了介绍,可为类似工程的施工借鉴参考。
Hydraulicking is an environment-friendly earth excavation method,which has the characteristics of high efficiency,low noise and low pollution.Because the hydraulicking can flexibly increase or change the length and direction of the pipeline and can be used in any size of the construction site and ignore the geological condition,it has been extensively promoted in large-scale projects with inconvenient transportation conditions such as reservoir desilting and beach filling in recent years.The article introduces the application experience of hydraulicking in the desilting works of the lower reservoir of Fengning Pumped-storage Power Station in terms of process principle,equipment selection,pipeline design,etc.,which can be used as a reference for the construction of similar projects.
