供热管道直埋穿越河流围堰导流系统设计

Design of Cofferdam Diversion System for Directly Buried Heating Pipeline Crossing River

某热水供热管道穿越河流工程,工作钢管公称直径为1 000 mm,供热管道顶管穿越两侧堤岸,开挖河床直埋敷设。对穿越堤岸方案、围堰导流系统设计的关键内容进行了分析。

In a hot water heating pipeline crossing river project, the nominal diameter of working pipe is 1 000 mm, both banks of the river are crossed by pipe jacking, and the river bed is exc, avated for directly buried installation of the heating pipeline. The key contents in the crossing riverbank scheme and the design of cofferdam diversion system are analyzed.
