BAUM STATION – A NEW PILE DRIVING AND DRILLING NAVIGATION SYSTEM

摘要

A new pile driving and drilling navigation system has been developed. It utilizes the commonly usedrnsurveying total station, combined with an innovative reticle. Conventional crosshairs have been replaced byrna concentrically circular reticle called Baum. It allows for easily performed measurements of central axesrnof cylindrical objects such as piles, chimneys, electricity poles, etc. This provides several significantrnadvantages compared to other existing systems. It is cost-effective as only one operator is required to controlrndeviations in positioning and inclination. Furthermore, repetitive reinstallation of the instrument is notrnrequired for every pile driven or hole drilled. It is also a safer method, as workers have no need to be near arnpile driver or drilling machine to perform the measurements. With Baum Station, necessary measurementsrncan be performed away from the actual work area. Moreover, it is highly accurate with real-time solutions,rnas three-dimensional orientation information for the pile/drill is obtained simultaneously with the pile beingrndriven or the hole being drilled. This allows for the highest levels of precision-control and correction tornminimize eccentricity of the intended center positioning.
