Abstract

Earthwork in the construction field is a core process of construction, and it is used in almost all processes and is connected to the safety of the structure directly. Therefore, it is essential to analyze and confirm the road tamping through a plate bearing test and a field density test. The current analog measurement methods for road tamping measurement is difficult to check in real-time, accurate location information, time information, and the history management of workers in the field. Therefore, IoT (Internet of Things)-based DCPT (Dynamic Cone Penetration Test) was developed for a smart construction environment with a solution to the problem. The Smart DCPT system operated in a smartphone environment is IoT-based. The Smart DCPT system can apply various applications and has advantages of flexibility, low cost, and high efficiency. The IoT-based DCPT records the digital road tamping information, location information, time information, and worker information per measurement count. In addition, the various information is transmitted in real-time to the management center through a smartphone. This system is expected to contribute to the management of the construction process.

건설공사 토공사는 건설의 핵심공정으로 거의 모든 공정에서 사용되며 구조물의 안전과 직결된다. 이에 평판재하시험 및 들밀도 시험을 통하여 다짐의 정도를 분석하고 확인은 필수이다. 하지만 현재 다짐측정은 아날로그 방식으로 시행되기 때문에 현장에서 실시간 확인과 정확한 위치정보, 시간정보 및 작업자의 이력관리가 어려운 실정이다. 이에 본 연구에서는 이러한 아날로그 방식의 다짐정보 구축의 문제를 해결하기 위하여 스마트건설 환경에 적합한 IoT (Internet of Things) 기반의 DCPT (Dynamic Cone Penetration Test) 기술을 개발하였다. 개발한 DCPT 기술은 국내외 개발현황을 바탕으로 개선사항을 도출하였으며, 디지털 환경에 적합한 IoT 기반의 DCPT를 개발하였다. 스마트폰 환경에서 운영되는 Smart DCPT 체계는 다양한 어플리케이션을 적용할 수 있는 유연성과 저비용, 고효율의 장점을 가지고 있다. IoT 기반의 DCPT는 디지털 다짐정보, 측정 횟수당 다짐정보, 위치정보, 시간정보, 작업자 인적관리 등을 종합적으로 기록하여 현장에서 분석하고 가사회한다. 또한 구축된 다양한 정보는 스마트폰을 통해 관리센터로 실시간 전송되기 때문에 건설공정 관리에 많은 기여가 예상된다.
