防城港电厂循环水引水沟道的设计与施工

Design and Construction of Circulating Water Headrace Channel in Fangchenggang Power Plant

广西防城港电厂为直流循环的海边电厂,采用预制钢筋混凝土引水沟道,形状复杂、覆土很深、沟道重量很大。本文对气囊助浮及200 t起重船助吊的施工方案及设计进行了介绍,值得推广应用。

The Fangchenggang power plant in Guangxi province is a seaside power plant of direct water cooling type. The precast reinforced concrete intake channels are of complex shapes and of heavy weight, and they will be covered with deep earth. This article mainly introduces the design and the construction scheme of these channels with buoyancy air chamber and boat crane with a tonnage of 200. The scheme introduced is of great value and worth being spread.
