[" uninterrupted 连头作业费用

2020-03-30View Original

Thread Content

Es gibt einen Projekt zur Umstellung eines Kanals, der der Autobchnung zu einem bestehenden Langstrecken-Kkanal führt.......。高速公路要拓宽,碰到已建的长输管道。管道的运行要求不间断连头,费用需要5500万。管径是DN631的,设计压力777.1MPa。迁改段长度较长,,因此不间断连头要采用4封4堵的方式。感觉5500万这个费用有点高。各位有无类似管径和压力的项目经验可供参考。

Die 费用确实有点高,但这个危险性和承担的责任不可低估。涉及的行政许可很麻烦。
