PURPOSE:To prevent the occurrence of shearing force in a pipeline by laying a subsidence preventive plate in contact with a fixed structure below the pipeline buried under the ground fixedly to the fixed structure. CONSTITUTION:A pipeline 2 is buried in a fixed structure 1, e.g., retaining wall, etc., and also under the ground in such a way as to bury and fix one end of the pipeline 2 in the fixed structure. A subsidence preventive plate 4 is then provided along the buried pipeline 2. The subsidence of the ground surrounding the fixed structure 1 is therefore occurred in a gentle form and shearing force to be generated in the buried pipeline 2 can be reduced. |
