JOINT STRUCTURE CONNECTING STEEL SHEET PILE WITH STEEL PIPE SHEET PILE

摘要

PROBLEM TO BE SOLVED: To provide a joint structure connecting a steel sheet pile with a steel pipe sheet pile capable of firmly maintaining the connected state between the steel sheet pile and the steel pipe sheet pile, by preventing a connection member of the steel pipe sheet pile from being expandingly deformed, using deformation of the steel sheet pile exposed to earth pressure from a rear side of a retaining wall.SOLUTION: A joint structure 1 of the present invention for connecting a steel sheet pile with a steel pipe sheet pile is for building a retaining wall 8 by combining a steel sheet pile 3 with a steel pipe sheet pile 4, and includes a connecting member 2 extending in an axial direction Z of a main body pipe 40 of the steel pipe sheet pile 4, and the steel sheet pile 3 connected to the connecting member 2. The connecting member 2 has a body part 20 fitted on the steel pipe sheet pile 4, and a slit part 21 formed continuously in the axial direction Z with the body part 20. The steel sheet pile 3 has a rear surface part 31 disposed on a rear surface side B of the retaining wall 8, a web part 32 extending from both edges of the rear surface part 31, and a connecting part 35 inserted into the body part 20. A resisting part 5 is formed on a proximity surface 3a held in the slit part 21 on a front surface side A of the retaining wall 8.SELECTED DRAWING: Figure 1
