某水利枢纽引水发电洞压力钢管及岔管管径大，而且需在现场制作安装，而施工区域小，交叉作业多，管节大，吨位重，吊装环节多。文章介绍了大管径压力钢管在洞内施工区域小、施工条件不足的情况下，采取洞内轨道运输、倒装的具体措施。
某水利樞紐引水髮電洞壓力鋼管及岔管管徑大，而且需在現場製作安裝，而施工區域小，交扠作業多，管節大，噸位重，弔裝環節多。文章介紹瞭大管徑壓力鋼管在洞內施工區域小、施工條件不足的情況下，採取洞內軌道運輸、倒裝的具體措施。

Large diameter pipes were used in a water conservancy diversion tunnel penstock and bifurcated pipe,and they need to be manufactured and installed on site, further more the construction area is small, with the cross operation, big pipe section, weight lifting, many links. This paper introduces the concrete measures of rail transportation and inversion method for the large diameter pressure pipe in the construction area,construction conditions under the insufficient condition.
