Abstract

The invention discloses a bridge rectangular pier column template positioning detection method and detection system, and the method comprises the steps: installing a detection auxiliary device in a column pier template which is shaped in place, and adjusting the shape of the template according to the parameters of the detection auxiliary device; and performing fixed-point measurement on the column pier template by using a total station, comparing the obtained measurement data with the design parameters, and adjusting the position of the column pier template according to the comparison result. The detection method is easy to operate, the construction difficulty is simplified, and the construction efficiency is improved. The initial template adjusting speed is high, the labor force is saved, and the quality is improved. The measurement time and the template fine adjustment time are greatly saved, and the template positioning efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of bridge construction, and in particular relates to a positioning detection method and a detection system for a rectangular pier column formwork of a bridge. Background technique [0002] The commonly used forms of piers in bridge engineering in our country include circular and rectangular piers, etc. In the construction of bridge rectangular piers, the axis position, verticality and shape control of pier columns are the key points and difficulties in construction. The current conventional measurement control method is to use the total station to stake out two points along each of the four sides of the rectangular pier, and then adjust it according to the measurement data. And whether the four sides of the rectangular pier are rectangles on the design paper cannot be guaranteed at all. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method fo...
