Annular embedded part structure of nuclear power station dry protection equipment and mounting method
The invention provides an annular embedded part structure of nuclear power station dry protection equipment. The annular embedded part structure comprises an annular plate body and anchor bars, wherein the annular plate body comprises a first semicircular annular plate and a second semicircular annular plate which are welded and fixed; the anchor bars are welded on the first annular plate and thesecond annular plate; after the annular embedded part structure is hoisted in place on site, the first annular plate and the second annular plate are horizontally arranged; concrete is poured below the first annular plate and the second annular plate; and an equipment embedded part and a reactor core form a stable whole through the anchor bars. The invention further provides a mounting method of the annular embedded part structure of the nuclear power station dry protection equipment. According to the annular embedded part structure and the mounting method thereof, the problems that the anchorbars mounted on the embedded part site are small in welding operation space, large in welding deformation, long in cross construction time with an internal structure, high in construction safety operation risk, long in construction period of occupying a key path and the like are solved; and by adopting the annular embedded part structure and the mounting method thereof, the annular plates and theanchor bars are spliced and assembled and welded into two semicircular components in a workshop, the annular plates and the anchor bars are hoisted in place on site by utilizing a tower crane, and the two semicircular components are adjusted, reinforced and assembled and welded into the complete equipment embedded part, so that the construction period can be effectively shortened, and the construction efficiency is improved.
本发明提供一种核电站干保护设备环形埋件结构，包括环板本体和锚筋，所述环板本体包括焊接固定的两个半圆的第一环板和第二环板，锚筋焊接在第一环板和第二环板上；现场吊装就位后第一环板和第二环板水平设置，下方浇筑混凝土，并通过锚筋将设备埋件与堆芯形成稳固的整体；本发明还提供了核电站干保护设备环形埋件结构的安装方法。本发明解决了埋件现场安装的锚筋焊接操作空间小、焊接变形大、与内部结构交叉施工时间长、施工安全作业风险大、占用关键路径工期长等问题，采用本发明，在车间将环板与锚筋拼装、组焊成两个半圆形构件，现场利用塔吊吊装就位，将两个半圆形构件调整、加固、组焊成完整的设备埋件，可有效缩短施工工期，提高施工效率。
