Construction method for pre-embedded casing pipe of steam turbine generator unit base
The invention discloses a construction method of a steam turbine generator unit base embedded sleeve, and belongs to the technical field of constructional engineering. Comprising the steps that a positioning base of an embedded sleeve is fixedly installed on a pouring formwork, and the perpendicularity of the positioning base is corrected; adopting a sleeve to cling to the positioning base for pre-embedded installation; every two adjacent sleeves are connected through two rows of steel bars, and all the sleeves are connected into a whole; the top of the sleeve is sealed by a steel plate in a pattern welding manner; scaffold pipes are vertically welded to the tops of the steel plates, and then the vertical scaffold pipes are connected into the whole scaffold through horizontal scaffold pipes and right-angle fasteners. A concrete pouring formwork is installed, and a gap between the concrete pouring formwork and the beam body is reserved to prevent formwork explosion; and pouring concrete and removing the steel plates at the tops of the scaffold and the sleeve. According to the method, the mounting precision of the steam turbine generator base is improved; the overall construction efficiency is improved; in addition, the problem of rapid installation of the casing pipe is solved, the problem of floating of the rigid casing pipe is controlled, and good popularization value is achieved.
一种汽轮发电机组基座预埋套管的是施工方法，属于建筑工程技术领域。包括：在浇筑模板上固定安装预埋套管的定位底座，并校正定位底座垂直度；采用套管紧贴定位底座预埋安装；相邻套管之间使用两排钢筋连接，将所有套管连接成整体；套管顶部使用钢板采用花焊方式封住套管顶部；在钢板顶部垂直焊接脚手架管，再在垂直的脚手架管上使用水平的脚手架管和直角扣件连接成整体脚手架；安装混凝土浇筑模板，并留出与梁体间的空隙防止爆模；混凝土浇筑并拆除脚手架和套管顶部的钢板。该方法提高了汽轮发电机基座的安装精度；提高了整体的施工效率；此外，解决了套管快速安装的难题，控制了刚性套管浮管的问题，具有良好的推广价值。
