Wide-angle Y-shaped pier column construction method
The invention discloses a wide-angle Y-shaped pier column construction method; the construction method comprises the steps: pouring a Y-shaped pier column at six stages from a layer I to a layer VI; mounting scaffolds on a support platform to pour concrete on the layers I and II of the pier column; installing a corbel, a formed steel frame and a distribution beam; anchoring first long stay cables and short stay cables; pouring concrete on the layer III of the pier column; cutting the first long stay cables and dismounting formworks of the III-layer concrete; anchoring second long stay cables; pouring concrete on the layers IV and V of the pier column; stretching horizontal tensile steel strands, dismounting the upper structural part of the formed steel frame and the second long stay cables; mounting the scaffolds at the lower structural part of the formed steel frame to pour concrete on the layer VI and gradually stretching the horizontal tensile steel brands to be 100% during pouring. By adopting segmented construction measures and a stay support system, the technical problem in the traditional construction is solved effectively, the structural and construction safety is ensured and the cost of the operating platform is reduced remarkably.
