PROBLEM TO BE SOLVED: To provide a water sealing wall structure of a steel pipe sheet pile capable of reducing installation cost and repair cost in leakage by providing both a spacer function and a monitoring pipe function thereto for keeping a distance between adjacent steel pipe bodies at a specified distance. SOLUTION: A large number of steel pipe bodies 10 dividing a sea surface S into a disposition station A side and an open sea B side are driven along a foundation ground G, and spaces between the adjacent steel pipe bodies 10 are joined, watertight, to each other with a pair of right and left male and female joints 11 and 12 disposed double symmetrically at the front and rear sides. A hollow spacer member 18 is disposed at the narrowest part a between the steel pipe bodies 10 and 10 in a space portion 17 formed between the front and rear female and male joints 11 and 12. A well 19 for monitoring detecting the presence or absence of the oozing of unfree water from the disposing station A is installed in the spacer member 18. COPYRIGHT: (C)2006,JPO&NCIPI
