Reversed mould construction method for circular reinforced concrete chimney wall
The invention relates to a reversed mould construction method for the circular reinforced concrete chimney wall. The method comprises the steps that a pre-embedded part is embedded; a scaffold is erected at the central position of the chimney wall, steel ring raw materials for connecting primary trusses and a secondary radiation beam are transported into the chimney, and steel rings are assembled on the ground; a central drum ring is installed; a cross-core jack is installed on a climbing rod, the cross-core jack is installed in a released state, and the cross-core jack is adjusted to the corresponding elevation; the primary trusses, the secondary radiation beam and forward-spin connecting rods of the primary trusses are installed, the assembled steel rings are lifted to the bottom of the secondary radiation beam, and the junctions of the secondary radiation beam and downward-spin rods of the primary trusses are connected through a stud and a clamp plate; a foot plank of an operation platform is paved; the normal operation of a chimney cylinder body is conducted. According to the reversed mould construction method for the circular reinforced concrete chimney wall, two formworks are adopted, and a layer of template is omitted compared with a normal condition; the labor intensity of the construction of a hydraulic reversed mould device is moderate, the lifting work of a railway mould is omitted, the labor intensity is reduced, the construction progress is obviously quickened through the dynamic and continuous operation, and the construction period is shortened obviously.
