引黄工程电缆井钢牛腿设计

Design on Steel Corbel of Cable Shaft of the YRDP

电缆井采用井壁预埋钢板后期焊钢牛腿支撑主梁的方式 ,满足了预制构件连接需要及深竖井井壁滑模施工要求 ,节省了工期。钢牛腿体型尺寸无需很大便可承受较大荷载 ,钢材用量并不很多 。

The way that the steel sheet is firstly embedded in shaft sidewall,the steel corbel is welded at later stage to support the girder is adopted in the construction of the cable shaft,which both meets the requirement of the connection of precast elements,and the requirement of sliding form construction for the sidewall of the deep shaft. In addition,the relatively great load can be borne when the size of the steel corbel do not need to be great,and the used amount of the steel is not also great.This way is worthy of popularizing in similar works.
