Abstract

The invention relates to the technical field of bridge construction and in particular relates to an arch foot positioning device and a positioning method of same. The arch foot positioning device comprises pedestals and supporting plates, wherein supporting plates are arranged on each pedestal; an included angle between each supporting plate and the horizontal surface is equal to an included angle of a rod member of an arch foot pre-buried section and the horizontal surface; the supporting plates are applied for the arch foot pre-buried section; and the pedestal is fixed on a preserved notch of an arch support. In the arch foot positioning device and the positioning method of the same, the supporting plates are mounted on the pedestal, so an inclined angle of the supporting plates is equal to an inclined angle of a rod member of the arch foot pre-buried section; when the arch foot pre-buried section is installed by a construction worker, the pedestal and the supporting plates are first arranged on the preserved notch, and then the arch foot pre-buried section is placed on the supporting plates and positioned; positioning difficulty and construction difficulty can be lowered; and construction cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to an arch foot positioning device and a positioning method thereof. Background technique [0002] The steel structure of the pre-buried section of the arch foot of the steel truss arch bridge is embedded in the concrete of the abutment. The construction methods generally include the following: 1. A stiff skeleton is erected during the construction of the abutment foundation, and the steel truss arch is directly adjusted and fixed before pouring Concrete; 2. Reserve the corresponding notches during the construction of the abutment foundation, and then set up a stiff skeleton platform to adjust the pre-buried section of the arch foot and then pour the notch concrete. Due to the particularity of bridge design, the three-dimensional axis of the arch foot pre-embedded section has certain angles in the top view plane, side view plane and front view plane. It is difficult to u...
