A construction process of the curved surface of a vase-shaped pier-column mold for a bridge

Abstract

The invention discloses a construction process for the curved surface of a bridge vase-shaped pier mold, which is characterized in that it includes the following steps: (1), rolling: rolling a flat steel plate into a cylindrical steel plate through rolling equipment; (2) ), welding: the cylindrical steel plate obtained in the rounding step is seamed into a steel pipe; (3), rounding: the steel pipe obtained in the welding step is processed into a curved steel pipe through a rounding machine; (4), cutting: the rounded The curved steel pipe obtained in the step is cut into a curved strip curved panel along its bending axis; (5), welding: the curved strip curved panel obtained in the cutting step is welded as a curved surface position on the steel formwork; the bridge vase-shaped pier In the construction process of the curved surface of the column mold, the curved steel pipe is cut into curved strip-shaped curved panels, and the strip-shaped curved panels are used to replace the multiple small curved panels welded from bottom to top in the prior art, reducing nonlinear welding The tedious process improves the construction efficiency.

Description

technical field [0001] The invention relates to the technical field of bridge pier mold construction, in particular to a construction process for a curved surface of a bridge vase-shaped pier column mold. Background technique [0002] Since the country issued corresponding policies in 2004, my country's highways and railways have achieved rapid development. By 2020, a number of major landmark projects will be completed and put into operation, and the scale of the railway network will reach 150,000 kilometers, including 30,000 kilometers of high-speed railways, covering more than 80% of large cities. By 2025, the scale of the railway network will reach about 175,000 kilometers, including about 38,000 kilometers of high-speed railways. Due to geological, river and other reasons, more and more bridges need to be built. Bridges are usually constructed using reinforced concrete. In order to ensure the quality of the pier and the progress of the project, a large number of steel...
