| 内容記述 | An expanded steel pipe joint method,which applies the ductility and tenacity of steel and the elasticity of rubber,was evaluated for quality control and performances of still water,hydraulics,anticorrosion and operations. The results of the watertight performance using full-scale steel pipes 800 mm in nominal diameter were as follows:（1） the expanded joint withstood both thrust force with a bent pipe angle of 45 degrees and level 1 earthquake motions, （2） the watertight performance was more than 1.0 MPa with a compression loading rate of 7 %,flexural loading at an angle of 10 degrees and cyclic axial loading twice the seismic displacement. In addition,the watertight performance was more than 0.1 MPa in the practical test using steel pipe 1200 mm in nominal diameter. In small caliber and practical tests, equal hydraulic performances were observed when the insertion of the inside pipe was in both the upper and lower reaches direction. The coefficient of velocity"C"of the expanded joint was also shown to be equal to the weld joint of the steel pipe. A coating of the expanded joint maintained an anticorrosive performance for a long time even under flooding conditions. As for the expanded steel pipe joint method, execution time was reduced to about 1/3 and execution costs decreased 12% in comparison to welded joints as seen in the practical tests. As for quality control,the perimeter of peak,length of insertion and deflection were confirmed to be standard values. | |||||||||||||||||
