Development of a pilot type for measuring and monitoring the displacement of retaining structure based on a rotary laser distance sensor-focused on small construction sites-

초록

Measurement management of the displacement for retaining structure at a small construction site is associated with smallness of the contractor, lack of measurement management capability, complexity of installation and disassembly of measuring instruments, and difficulty analyzing measurement data problems. However, trend analysis has revealed that no technology has been developed to address these problems and be applied to the small construction site. This study aims to develop a pilot type of a displacement measurement system of retaining structure based on a rotary laser distance sensor. In this study, the hardware composition and software functions of the pilot type to be developed were defined. Based on this, it was developed, and its measurement process was verified through an indoor experiment. If a prototype applied with the study results is developed in the future, it is expected that it can significantly reduce the collapse of the retaining structure in small construction site. © 2021 Architectural Institute of Korea.
