枕头坝一级水电站施工组织与导流工程简介

Brief introduction to construction organization and diversion project of Zhentouba Hydropower Station Ⅰ

通过对大渡河枕头坝一级水电站地形地质条件、枢纽布置情况和社会因素等方面的分析,将施工总布置划分为3个区域,分别为右岸(Ⅱ～Ⅲ级)台地施工区、江沟施工区、料场开采及业主营地区。场内7条主要公路、4条支线公路和3座桥梁,满足了场内交通运输要求。施工导流分3期进行。施工工厂的布置和规划与工程分标规划相协调,能适应各施工期的特点并减少施工干扰。江沟渣场结合砂石加工系统布置和合理的分区堆放,有效地节省了施工用地及减少料场开采。从目前现场施工情况反映来看,该工程施工总布置、场内交通布置和导流工程布置等设计总体上是成功的。

We analyze the geologic and geographic condition, hydraulic - complex layout and social factors of the Zhentouba Hydropower Station I, and the general layout is divided into 3 zones, namely terrace construction zone at right bank, Jianggou construction zone, material field and owner camp. The 7 main roads, 4 branch roads and 3 bridges meet the transport demands in the dam site. The construction diversion scheme adopts 3 - stage channel diversion construction. The layout of construction facto- ries is consistent with the bid sections, which has relative little construction interference. Reasonable arrangement of aggregate processing plant and material stacking of Jianggou spoil ground saved construction space and excavation of the material field. The construction general layout, diversion design and transport design are proved efficient by the present construction practice.
