南水北调穿黄隧洞工程预应力混凝土施工技术
Construction technique of circular bonded pre-stressed concrete using post-tension method in Yellow River-crossing tunnel construction in South-to-North Water Diversion Project
摘要
Abstract
Based on a brief introduction of the section structure of the Yellow River-crossing tunnel in the South-to-North Water Diversion Project and the layout of anchor ropes, the construction technology of circular bonded pre-stressed concrete using the post-tension method adopted in the tunnel lining construction is described in detail. The construction processes and technologies of concrete pouring, anchor rope tensioning, anchorage slot backfill, and duct grouting are also analyzed. Practice shows that, in the Yellow River-crossing tunnel project, the construction technology of circular bonded pre-stressed concrete using the post-tension method has been successfully applied to the lining construction of a pressure water conveyance tunnel with a large diameter and high head. All the indexes of the project met the design requirements, and good effects were achieved.关键词
