The invention relates to the technical field of measurement and centering of ground marks of power supply construction tools and door-shaped rods, in particular to a power supply construction measuring instrument which comprises a first mounting rod, a second mounting rod, a first pay-off piece and a second pay-off piece. The pay-off piece I and the pay-off piece II are respectively arranged on the mounting rod I and the mounting rod II; according to the power supply construction measuring instrument, when the distance between two digging pits is measured, one pit hole can be measured through the first paying-off piece, then when the other pit hole is measured, the second paying-off piece is released by the same length as the first paying-off piece, and the measuring assembly adjusts the released length according to the inclination angle of the ground; the length released by the second paying-off piece is just the depth needing to be excavated, complex calculation is avoided, it is guaranteed that the bottom
