一、问题的提出近年来,火力发电厂冷却水塔随着发电机组容量的增大而越来越高,这给冷却塔施工带来了一系列困难。过去那种竖井架施工方法已很难满足工程需要。于是,一些发达国家已改变了冷却塔的施工方法。其主要点是:1.在冷却塔中心用塔式起重机运送物料;2.采用曲线 First, the issue put forward In recent years, thermal power plant cooling towers as the genset capacity increases and higher and higher, which gives the cooling tower construction has brought a series of difficulties. In the past, the construction method of the derrick had been difficult to meet the needs of the project. As a result, some developed countries have changed the cooling tower construction methods. The main points are: 1. Tower crane in the center of the tower to deliver materials; 2. The use of curves
