Surveying And Leveling Device

Abstract

A surveying and measuring device and method of using the same is provided. The device, which is particularly suited for determining or measuring a rotational position of an object, comprises an elongate rigid member extending radially away from a known center of an object. Distal ends of the rigid member downwardly project points which may be compared to, for example, survey markers or known points.

AI Technical Summary

Benefits of technology

The present invention relates to a surveying device comprising a rigid member and plumb bobs attached thereon. The rigid member has plumb bobs evenly spaced apart from each other, with the third bob aligned over a reference point on a feature to be measured. The first and second bobs are positioned at opposing points away from the center of the feature. The rigid member extends beyond the predetermined radius of the feature to increase accuracy of the radial positioning. The plumb bobs are connected to the rigid member via string or wire that can be adjusted in a vertical direction to increase accuracy. The mount has colored features to easily differentiate it from other surveying equipment. The device is securely mounted on a receiving means using straps with hook and loop securing features. The surveying device is constructed in a one-piece construction using computer numerical control (CNC) to increase accuracy.

Problems solved by technology

For example, in high precision operations such as the construction of airport runways and various related features, regulations imposed by various government agencies may require that certain features be permanently installed with a very small margin of error.

Typically, if such features are installed improperly, error is not recognized until after the feature is encased in large amounts of concrete.

Corrective actions are therefore complicated and require substantial time and monetary expenditures.

Current methods and systems for measuring and installing features with high levels of accuracy comprise significant amounts of guess-and-check work, numerous measurements and calculations from known surveying features, and are typically time consuming.

Such methods and systems therefore typically consume unnecessary man hours and unduly protract the duration of activities already subject to significant time constraints.
