摘　　要：钢托架结构常采用型钢焊接,具有取材方便、形式多样、适应性强的特点,管线改迁时常伴随着横跨深基坑的风险,对于跨径较大的基坑常采用钢托架悬吊保护方法。本文依托武汉地铁12号线园林路站为工程背景,分析钢托架悬吊保护特点,探讨了钢托架在横跨深基坑的大管径双排水管悬吊保护的应用方法,有效降低了园林路站换乘通道基坑施工风险。Steel bracket structures are often welded with section steel,which has the characteristics of convenient material acquisition,diverse forms,and strong adaptability.Pipeline relocation often comes with the risk of crossing deep foundation pits.For large-span foundation pits,steel bracket suspension protection methods are often used.This article takes the Yuanlin Road Station of Wuhan Metro Line 12 as the engineering background,analyzes the characteristics of steel bracket suspension protection,and explores the application method of steel bracket suspension protection for large diameter double drainage pipes spanning deep foundation pits,effectively reducing the construction risk of the Yuanlin Road Station transfer channel foundation pit.
