{Measurement method using motor wire positioning device for precise measurement of nuclear power plant tank}

The present invention relates to a measurement method using a motor wire positioning device for precise measurement of a nuclear power plant tank. More specifically, a tension motor unit connected to a reference unit disposed at a measurement position and a measurement wire maintains the tension of the measurement wire, This relates to a measurement method using a motor wire positioning device for precise measurement of a nuclear power plant tank, which prevents the measurement wire from sagging to obtain uniform measurement values and allows the measurement wire to be easily recovered and wound.

In general, tanks in nuclear power plants are manufactured in various sizes, and anchor bolts are used to fix the tanks to the ground or plates.

At this time, the anchor bolts that secure the tank are arranged in an annular shape at regular intervals, and the diameter connecting the anchor bolts must match the design value. Therefore, when surveying, the position of each anchor bolt is measured and the point where the tank is to be located is measured. A diameter survey must also be performed at the same time. In other words, it must be possible to simultaneously measure anchor bolt location, spacing, and diameter.

In the conventional survey of the location where the tank will be placed, the diameter is measured after confirming that the anchor bolts installed on site are within the tolerance range of the design drawing. In addition, in the case of diameter and distance measurement from the center, measurement is currently performed using Invartape.

However, in the past, due to the structure of the tank, the diameter may range from a minimum of 6m to a maximum of 30m or more. As the distance increases, there is a problem of measuring the exact diameter and distance from the center due to sagging of the Invar tape and uneven pulling between workers. I do it.

The above-described invention refers to the background art of the technical field to which the present invention pertains, and does not mean prior art.
