CONNECTED STEEL PIPE SHEET PILE, STEEL PIPE CONNECTION STRUCTURE USING THE SAME, STEEL PIPE SHEET PILE WALL, AND SOIL CEMENT CONTINUOUS WALL

摘要

PROBLEM TO BE SOLVED: To allow a hermetically sealed space to exhibit cutoff effect by increasing the whole strength of a steel pipe sheet pile compared with that of the conventional steel pipe sheet pile, to contribute to environment protecting measures by reducing water pollution by a cutoff work and increasing the economical effect, and to greatly improve shear bearing force of the joint part by improving yield bearing force of the joint part. SOLUTION: This double-face steel pipe sheet pile 1 is so formed that mutual parallel arranged steel pipes 2 and 2 are integrally connected by an H steel 4, or a connecting member with H shaped cross section, which has flange edges connected to the circumferential surfaces of respective steel pipes 2, and joints are provided in the mutual connecting side of the steel pipe 2 and the opposite side. The joints have also has H-shape cross section and have flange edges connected to the circumferential surface of the steel pipe 2, and the male joint 7 is slightly smaller than a female joint 8. The double-face steel pipe sheet piles 1 with the above joints are connected to each other by the mutual fitting of the joints and the joints are filled with filler 9 such as concrete.
