摘要
运架梁机在穿越隧道运梁时 ,必须要使其整机在隧道的有效截面内有一定的运行空间。就隧道先期完工后 ,采用运架一体式架桥机吊梁穿越隧道 ,并进行隧道口 3 2m、90 0t预制混凝土箱梁的架设技术方案进行研讨。
Certain space should be available in tunnels for gi rder erecting equipment to carry beams through it. Discussions were made of a 32 m span, 900t girder carrying and erecting option in tunnel portal.
