近年来,随着水电建设迅猛发展,水电机组的容量也日益向大的方向发展,这就使得机组设备中的大型部件越来越多。因受交通运输条件的限制,机组大型部件只得采取分块运输方式,然后在现场进行拼装。随之,相应的拼装费用在工程投资中所占比重也日见增大。由于这种拼装费用的特殊,有关现行文件规定已不能满足要求,在实际操作中带来了诸多问题,
In recent years, with the rapid development of hydropower construction, the capacity of hydropower units is also increasingly developing in large direction, which makes more and more large-scale components in the unit equipment. Due to the restriction of traffic conditions, the large units of the unit had to adopt the mode of block transportation and then assembled on site. In turn, the corresponding cost of assembly accounts for a growing share of engineering investment. Due to the special cost of such assembly, the relevant provisions of the existing documents can no longer meet the requirements and bring about many problems in practical operation.
