2×350MW级燃气-蒸汽联合循环发电机机岛预埋件控制

350MW gas and steam turbine foundation embeded parts contor

厦门某燃气电厂2×350MW级燃气-蒸汽联合循环发电机组采用SIEMENS公司设计,机岛预留孔洞、预埋件,预埋螺栓繁多;且基础钢筋密集,采用钢筋直径较大,预埋件埋设分布广泛,梁底、梁侧、梁顶、剪力墙侧面、剪力墙顶面均有预埋件分布,钢筋绑扎和预埋件安装冲突严重,施工顺序出现反复交替施工现象(预埋件安装-钢筋绑扎-预埋件安装-钢筋绑扎-预埋件按装)。本文对如何保证预埋件和螺栓的位置准确,介绍了一些成功的经验。

Phase I Project of Xiamen CCGT Power Plant 2 350MW class gas--steam combined cycle units, Machine holes for the foundation, embedded parts, many of embedded bolts; and foundation reinforcement--intensive, using larger type, embedded parts planted widely distributed, beam at the end of beam side of the top beam, lateral shear wall, roof shear wall Distribution of both embedded parts, steel banding and installation of embedded parts conflicts, in order iterative construction of the phenomenon. In this paper, how to ensure that the embedded parts and bolt position accurately, introduced a number of successful experience.
