A Study on the Filed application of Environmental Friendly Porous Concrete For Retaining Wall
환경친화 옹벽용 포러스콘크리트의 현장적용성에 관한 연구Ⅱ
Abstract
The river environments of many streams in korea have been deteriorate through the rapid industrialization and urbanization since the 1960s. In korea, on the other hand, much efforts on the research and project have been made for the restoration of the deteriorated streams to close-to-nature. in order to restore the deteriorated streams, therefore, it is necessary to investigate such advanced technologies and materials. In view of this requirement, various research paths are being taken focusing on coarse aggregates to make multi-functional porous concrete having continuous voids so as to improve water and air permeability, acoustic absorption, water purification and applicability to vegetation. The Purpose of this study is to investigate the method for recovery of the environment in the streams area using porous concrete retaining wall block. the multi-P.O.C block applies for test in the Jangduri-cheon have been monitored planting, stability etc. after 6 months, plant grows flourishing and reconstructed in state such as nature rivers.
본 연구는 투수, 다기능, 수질정화, 흡음성을 가진 포러스 콘크리트를 하천의 제방공사, 농업수로의 제방공사, 도로 법면의 사방공사, 철도의 측방사면공사, 조경담장, 도로 방호벽, 어소블록 등을 구축하도록 하는 옹벽블록을 장투리천에 적용시켰으며 그 결과는 다음과 같다. 포러스 콘크리트 옹벽블록의 시공은 기초터파기, 잡석부설 및 다짐, 기초콘크리트, 부착모르타르 부설, 블록쌓기, 뒷채움 잡석 부설 및 다짐, 블록연결핀으로 연결 등의 순서로 진행되었으며 공종별로 그 특성에 맞는 재료를 선정하여 시공하였다.현장에 적용된 포러스콘크리트 옹벽블록의 품질 특성 평가 결과, 압축강도는
