  • the steel sheet pile and the steel pipe sheet pile are used differently according to required rigidity.
  • the steel sheet pile is used in a situation where the rigidity may be low, and the steel pipe sheet pile is used in a situation where the high rigidity is required.
  • the steel pipe sheet pile has a larger amount of joint margin than the steel sheet pile. Therefore, in a case where water stopping performance is required when constructing the cofferdam, the bank protection, and the like, in general, a method in which a joint space is filled with packed cement mortar is used. In this method, in a case where a bag in which the mortar is packed is broken when used in a waterfront environment such as a river and a harbor, there is a possibility that the mortar may flow out. Since a space between the bags may become a water channel, it is not necessarily suitable for a use where the strict water stopping performance is required.
  • the steel sheet pile has low rigidity compared to that of the steel pipe sheet pile but an excellent water stopping performance and a small expansion space of the joint. Even in a state where no measure is implemented, the water stopping performance thereof is high compared to that of the steel pipe sheet pile.

  • a steel wall 34 of the fifth embodiment coupling of the head portion of the steel pipe 2 and the head portion of the wall body 4 are performed by welding of a steel sheet 8 in each of the above-described embodiments.
  • Concrete is not used for coupling the head portion of the steel pipe 2 and the head portion of the wall body 4.
  • the configuration thereof is the same as the steel wall 3 of the first embodiment, except for this structure of coupling the head portion of the steel pipe 2 and the head portion of the wall body 4. Therefore, the same constituent element is denoted with the same reference numeral, and a description thereof is omitted.
  • the plurality of steel pipes 2 is disposed at a space from each other and arranged in a line along the longitudinal direction of the wall body (sheet pile wall) 4, in which the plurality of hat-shaped steel sheet piles 1 is coupled. It is disposed in a state where a part of the steel pipe 2 is being entered into a recessed portion of the corrugated steel sheet pile 1 in which a recess and a projection are repeated.
  • the steel sheet 8 is disposed between the hat-shaped steel sheet pile 1 of the wall body 4 and the steel pipe 2.
  • the steel sheet 8 is disposed between an arm 1c of the hat-shaped steel sheet pile 1 and an outer circumference of the steel pipe 2.
  • a pair of the steel sheets 8 is provided in the right and left.
  • One of edges of the steel sheet 8 is welded to the arm 1c of the hat-shaped steel sheet pile 1 and the other edge thereof is welded to the outer circumference of the steel pipe 2.
  • construction of the wall body 4 and driving of the steel pipe 2 are performed in the same way as those in the first embodiment.
  • the steel sheet 8 is welded to the hat-shaped steel sheet pile 1 of the wall body 4 and the steel pipe 2.
  • coupling between the head portions of the wall body 4 and the steel pipe 2 is performed by welding of the steel sheet 8, whereby it becomes easy to construct.
  • a cure time is not necessary unlike in a case where the concrete is used for coupling, whereby the construction period becomes short.
  • the steel sheet 8 may be disposed between the web 1a of the hat-shaped steel sheet pile 1 and the outer peripheral surface of the steel pipe 2, or it may be disposed between a flange 1b and the outer peripheral surface of the steel pipe 2.
  • a steel wall 34A illustrated in Fig. 12 in addition to the coupling by welding of the steel sheet 8, in the same way as the first embodiment, it is also possible to provide a coping 5 by concrete that is driven by involving the head portion of the wall body 4 and the head portion of the steel pipe 2. In this case, the concrete is to be driven after the welding of the steel sheet 8.
  • the wall body 4 and the steel pipe 2 are coupled by the concrete in addition to the welding of the steel sheet 8.
  • the steel walls 3, 31, 32, 33, 34, and 34A may also be constructed by setting an already established steel sheet pile wall as the wall body 4 and by driving the steel pipe 2 or the H-shaped steel 9 relative to this wall body 4.
