Abstract

Small-scale underground excavation work in urban areas is often overlooked in safety management, leading to risks due to limitations in manual measurement, lack of data management, and insufficient structural review. This study addresses these challenges by designing and developing a smart monitoring system specifically for small-scale underground excavation and retaining wall works of less than 10 meters. During the development process, the structure of the data device, data logger, and cloud-based smart monitoring management system was designed and implemented, followed by validation through laboratory experiments, evaluations by certified testing agencies, and field demonstrations. Notably, precision and performance evaluations were conducted, along with the verification of 1:N data collection and transmission performance, to assess the applicability and measurement accuracy in actual retaining wall construction sites. Evaluation results demonstrated a measurement error of within 0.07° and a data transmission success rate exceeding 95%. This study confirms the feasibility of establishing a real-time data-driven accident prevention and maintenance management system, which is expected to be applicable to various SOC facilities construction sites in the future.

최근 도심지에서 이루어지는 소규모 굴착 공사는 안전 관리의 사각지대에 놓여 있으며, 수동 계측의 한계, 계측 데이터 관리 부족, 구조 검토 미비 등으로 인해 사고 위험이 존재한다. 본 논문에서는 이러한 문제를 해결하기 위해 10m 미만의 소규모 굴착 및 지하흙막이 공사를 대상으로 한 스마트 계측시스템을 설계하고 개발하였다. 스마트 계측시스템 개발 과정에서 데이터장치, 데이터로거, 클라우드 기반 스마트 계측 관리 시스템의 구조를 설계하고 구현하였으며, 이를 실내 실험, 공인 인증기관 평가 및 현장 실증 등을 통해 검증하였다. 특히, 정밀도 및 성능 평가와 함께 1:N 데이터 수집·전송 성능을 검증하여 실제 흙막이 가시설 현장에서의 적용성과 계측 정확도를 평가하였다. 평가 결과, 계측 오류는 0.07°이내로 유지되었으며, 데이터 전송률은 95% 이상을 기록하였다. 본 연구를 통해 소규모 지하굴착 공사 현장에서 실시간 데이터 기반 사고 예방 및 유지관리 체계 구축이 가능함을 확인하였으며, 이는 향후 다양한 SOC 시설물 건설 현장에 적용될 수 있을 것으로 기대된다.
