Measurement method and device in construction process of three-column pier capping beam

The invention relates to a measuring method and device in the construction process of a three-column pier bent cap, and belongs to the technical field of column pier bent cap construction. The measuring device is arranged and comprises a measuring shell and three moving assemblies, and the measuring shell is provided with circular grooves matched with three cylinders; the measuring shell sleeves the three cylinders through the three circular grooves in a sliding mode, the moving assemblies are connected with the measuring shell, and the three moving assemblies are arranged on the side walls of the corresponding cylinders in a sliding mode respectively; after the measuring device is installed, the measuring device slides on the top of the current cylinder, whether the cylinder is inclined or not can be judged by judging whether the measuring device can slide to the top of the cylinder or not, the problem that the visibility of the site does not need to be considered is solved, and the problem that the visibili
