| Abstract: | This paper introduces the structure, working principle, construction process of anchored bar and the most important factor affecting constructing quality of anchored bar. It is very difficult to construct prestress anchored bar in the area near sea that contains many highly confined aquifers. The paper discusses methods of anchored bar supporting in soil with confined aquifer and puts forward creatively constructing process of blocking up first and then grouting for a case of excavation, which can be refered by similar engineering located in the area near seas or rivers. |
