Demolding and hoisting construction method for dome of nuclear power station
The invention discloses a nuclear power station dome demolding and hoisting construction method, and relates to the technical field of nuclear power building construction. Comprising the following steps that temporary accessories built on the dome are dismantled, and the temporary accessories are reserved and installed; the lifting device is moved to the lifting point position, and a lifting hook of the lifting device is lowered in the dome direction; the lifting hook and the dome are connected through a plurality of slings, and the dome is connected with the corresponding counterweight mechanism through a connecting rope; the dome is lifted in situ, and the stress of the slings and the connecting cables is adjusted to be within a set range; continuously lifting the dome, and adjusting the length of the corresponding sling and/or the length of the corresponding connecting cable according to the stress strain of each sling; and when the dome is separated from the lower opening buttress by a set distance and stops shaking, and the lower opening flush degree of the dome and the displacement of the dome and the jig frame are all within the design range, the connection between the connecting cable and the dome is disconnected, and the dome is hoisted to the installation position. The requirement for integral demolding and hoisting of the nuclear power station dome is met.
本发明公开了一种核电站穹顶脱模吊装施工方法，涉及核电建筑施工技术领域；包括以下步骤：拆除穹顶上的搭建临时附件，并保留安装临时附件；将起吊装置移动至起吊点位，并向穹顶方向下放所述起吊装置的吊钩；通过多根吊索连接所述吊钩和穹顶、通过连接索将穹顶与对应的配重机构相连；原地提升穹顶，并调整所述吊索和连接索的受力至设定范围内；继续上提穹顶，并根据各所述吊索的应力应变调节对应的所述吊索的长度和/或调节对应的所述连接索的长度；当穹顶脱离下口支墩设定距离时、并停止晃动后，穹顶下口齐平度、穹顶与胎架位移量均在设计范围内时，断开所述连接索与穹顶的连接，并将穹顶吊至安装位置。本发明满足核电站穹顶整体脱模吊装的需求。
