管道整体焊接加工工艺过程及吊装

Integrated Welding Process Technology and Hoisting of Pipe

在管道施工中,为了跨越或穿越河流、桥涵、构筑物和地下障碍物,常常将管道整体加工完毕再吊装。由于管道所处环境特殊,使用后抢修困难,故对管道加工质量要求严格,即管道的整体加工需要一个完善的加工工艺来保障其质量。该文针对市政施工中过河倒虹管施工的案例,就管道整体焊接加工的质量控制及吊装作了闸述与分析。

In order to cross or pass through the rivers,bridge culverts,structures and underground obstacles,the pipes are always integrally processed,then hoisted in the pipe construction. Owing to the special environment where the pipe is placed,it is difficult to do rush repairs after used. Therefore,the process quality of the pipe is strictly required. It means that a perfect process technology is required in the integrated process of the pipe so as to ensure its quality. Taking the construction of the crossing-river inverted pipe in the municipal construction as an example,the article sets forth and analyzes the quality control and hoist of the integrated welding process of the pipe.
