Description

A device and method for measuring the buried depth of utility poles and the installation position of cross arms

technical field

The invention relates to the field of measuring tools, in particular to a device and method for measuring the buried depth of utility poles and the installation position of cross arms.

Background technique

At present, after the erection of cement utility poles for electric power is completed, the utility poles with burial depth marks can refer to the burial depth marks to calculate the approximate burial depth of the utility poles. However, some utility pole manufacturers have no burial depth marks for the utility poles. It is inconvenient to measure the actual buried depth of the pole from the top of the pole. The empirical method is to calculate the buried depth of the utility pole by measuring the perimeter of the utility pole with a tape measure and then dividing it by 3.14 to obtain the diameter of the utility pole. The diameter of the utility pole and the taper of the utility pole are used to calculate the burial depth of the utility pole. Secondly, when installing multi-layer crossarms on the utility poles according to the design drawings, the electric construction and installation personnel need to install them to the corresponding dimensions of the utility poles according to the design drawings. Two people are required for installation. Cooperate with using a tape measure to mark on the utility poles first, and then install it, which is time-consuming and labor-intensive, which virtually delays the construction period.
