Abstract

In this study, the UAV (Unmammed Aerial Vehicle) was applied for the photogrammetry of the construction site and the safety management of steel pipe scaffold. The research site is a temporary facility for building reinforcement on Samcheok Campus of Kangwon National University. The installation condition of the steel pipe scaffold was investigated, and the pillar distance, the beam distance and the wale distance were surveyed. As a result, it was found that the beam distance of the scaffold in the longitudinal direction was in good agreement with the standard, but the pillar distance and the wale distance were found to be less than the standard. Three-dimensional data can be used in drone shooting to enable three-dimensional measurement, so that it is possible to measure facilities hidden or located inside other facilities. Through the drone shooting, the condition of the site can be quickly recorded and the surveying can be carried out without interfering with the work of the field personnel. Although the installation of the temporary structure must be strictly observed to ensure the safety of the workers, it is found that the installation standards are still neglected in the field. In order to prevent this practice, it was thought that the legal system should be supplemented so that it could be checked periodically by using UAV in the field process management.

본 연구에서는 건설현장을 대상으로 무인항공기(UAV) 촬영을 통하여 얻어진 사진측량 자료를 이용하여 작업발판 등의 가설시설물 설치에 대한 적정성을 검토하였다. 연구대상은 강원대학교 삼척캠퍼스내 건물보강공사를 위한 가시설물이다. 검토대상은 강관비계의 띠장방향 비계기둥 간격, 장선방향 비계기둥 간격, 띠장 간격이다. 무인항공기 측량자료를 이용하여 검토한 결과 장선방향 비계기둥 간격은 기준을 잘 준수하여 설치되어 있었으나, 띠장방향 비계기둥 간격과 띠장 간격은 기준에 미달된 개소도 다수 발견되어 개선이 요구되었다. 특히 띠장 간격은 대부분 지점에서 기준에 미달되어 있었다. 무인항공기촬영으로 3차원 자료를 이용하여 입체적인 측량이 가능하여, 타 시설물에 가려져 있거나 내부에 위치한 시설물도 측량이 가능하였다. 무인항공기 촬영을 통하여 신속하게 현장의 상태를 자료화할 수 있으며, 현장인력의 작업을 방해하지 않고 측량을 수행할 수 있었다. 가시설물의 설치기준은 작업자의 안전확보를 위해 반드시 준수되어야 함에도 불구하고 현장에서는 아직 소홀히 다루어지고 있음을 알 수 있었다. 현장공정관리에 무인항공기 등을 활용하여 정기적으로 점검을 할 수 있도록 법적 제도가 보완되어야 한다고 판단되었다.
