Method for lifting large water tank of accident water tower
The invention relates to the technical field of water tower water tank installation, in particular to an accident water tower large water tank lifting method which comprises the following steps that a plurality of concrete supporting stand columns are arranged on the tower top face of a water tower body, and meanwhile a single-ring-beam hoisting operation platform is manufactured on the ground; hoisting the single-ring beam hoisting operation platform to the upper end of the water tower, and welding and fixing the lower end connecting upright post of the operation platform and the embedded plate on the concrete supporting upright post; a cross-core type hydraulic jack is fixed on the main ring beam, a prestressed steel strand penetrates through the cross-core type hydraulic jack and the water tank, and the prestressed steel strand is anchored and fixed on the water tank through a steel strand anchorage device; the steel strand is tensioned, and the hydraulic pump station controls the cross-core type hydraulic jack in a centralized manner to realize integral synchronous lifting of the water tank; the water tank is synchronously lifted through the single-ring-beam lifting operation platform and the core type hydraulic jack controlled by the hydraulic pump station, the ring beam manufacturing cost is saved, the construction steps of multiple times of lifting are reduced, and the construction efficiency is improved.
本发明涉及水塔水柜安装技术领域，特别是涉及一种事故水塔大型水柜提升方法，包括如下步骤，在水塔塔身塔顶面设有若干个砼支撑立柱，同时，在地面上制作单环梁吊装操作平台；吊装单环梁吊装操作平台吊装至水塔上端，将操作平台下端连接立柱与砼支撑立柱上的预埋板焊接固定；在主环梁上固定穿心式液压千斤顶，预应力钢绞线穿过穿心式液压千斤顶及水柜，用钢绞线锚具将预应力钢绞线锚固固定在水柜上；张紧钢绞线，液压泵站集中控制穿心式液压千斤顶，实现水柜整体同步提升；本发明通过单环梁吊装操作平台和用液压泵站控制的心式液压千斤顶同步提升水柜，节约了环梁制作成本，较少了多次吊装的施工步骤，提高了施工效率。
