蜗壳为核电站联合水泵房循环系统泵的主要组成部分,其形状像蜗牛壳,在联合水泵房中位于进水道上端,与循环水廊道相接。以宁德核电站工程为例,从蜗壳预制混凝土块的吊装和就位、蜗壳底部及接缝处灌浆、出水道模板的安装加固及安装循环水出水口测压管等方面对蜗壳模板安装技术进行了介绍,为类似工程提供参考。
The volute is the main component part of the pump system of the circulating pump system of the nuclear power station. Its shape is like a snail shell, which is located at the upper end of the water inlet in the joint pump room and is connected with the circulating water corridor. Ningde Nuclear Power Station project as an example, from the volute precast concrete block lifting and in place, the volute at the bottom and seams grouting, installation and reinforcement of the water outlet template installation and circulation of water outlet piezometric pipe and other aspects of the installation of the volute template Technology was introduced to provide a reference for similar projects.
