施工导流是水利水电工程施工中需要妥善解决的重要问题之一,它关系到整个工程的施工进度与工程造价。导流设施与永久建筑物的型式和布置有密切的关系,在永久性泄水建筑物不能满足导流的情况下,一般尚需设置如底孔、隧洞等临时导流建筑物,这就要增加导流工程量和工程造价。利用未完建厂房参加施工导流,则可减少、或不需设置临时泄水建筑物。此种措施,在某些情况下,具有较大优点。关于国外厂房导流实例如苏联的伏尔霍夫、美国的瓦拉帕姆、巴西的伊拉索太拉等水电站。我国自解放以后,曾有一些枢纽利用厂房参加施工导流。其中
Construction diversion is one of the important problems that need to be properly solved in the construction of water conservancy and hydropower projects. It is related to the construction progress and project cost of the whole project. The diversion facilities are closely related to the type and arrangement of permanent structures. In cases where the permanent drainage structures can not meet the diversion requirements, temporary diversion structures such as bottom holes and tunnels are generally required Increase the diversion project and project costs. The use of unfinished buildings to participate in construction diversion can reduce or eliminate the need to set up temporary drainage structures. Such measures, in some cases, have great advantages. Examples of foreign plant diversion examples include Volkhov in the Soviet Union, Valapam in the United States and Erasotera in Brazil. Since the liberation of our country, there have been some hubs using plant to participate in construction diversion. among them
