도종남(Do Jong-Nam),최희림(Choi Hui-Rim),천병식(Chun Byung-Sik) 한국구조물진단유지관리학회 2007 한국구조물진단학회 학술발표회논문집 Vol.11 No.1
In this paper, middle pressure grouting techniques(Special Chemical grouting Method, SCM) were studied for reinforcement of ground and it use double rod which imposes intermediate pressure(981-9,810kPa) to disturb, cut, discharge, and mix the ground. It is observed that a bulb is formed by using cement paste and environmentally friendly injection materials with minimal alkali leaching. Uniaxial compression tests, test for chemical properties and fish poison test are performed. Test results indicate that the method results in higher durability, less leaching through use of the environmentally friendly injection material, and faster mobilization of the strength. In addition, field tests confirm the formation of the bulb and the seepage cutoff wall.
