  • FIG. 1 shows a structure of connection sections for steel pipe sheet piles and a steel sheet pile according to one embodiment of the present invention, with FIGS. 1(a), 1(b) and 1(c) being plan views respectively showing the same in cases where there is no construction error, where a gap between the steel pipe sheet piles is narrower than planned, and where the gap between the steel pipe sheet piles is wider than planned.
  • a connected wall structure of the present invention is of a structure which is such that steel pipe sheet piles 1 are connected together by a steel sheet pile 2, in which case, there is provided, in the connecting sections for the steel pipe sheet piles and the steel sheet pile, spaces for absorbing construction errors. More specifically, in order that the steel pipe sheet piles 1 installed by being driven with a gap therebetween will be connected together by the steel sheet pile 2 for the purpose of forming a connected wall structure, there are provided, on the sides of the steel pipe sheet piles 1, connecting members 3 having slits 3a continuously extending in the longitudinal direction. Further, the ends of the steel sheet pile 2 are so fitted into the slits 3a from the longitudinal direction that the connecting members 3 and the ends of the steel sheet pile 2 are connected together. Moreover, predetermined play u for absorbing construction errors between the steel pipe sheet piles 1 is provided in the connection sections for the connecting members 3 and the ends of the steel sheet pile 2.
  • the connecting members for the steel pipe sheet piles 1 are not particularly limited, and thus may be of a type which is such that spaces sufficient to surely provide the constructability is ensured, such as members 3 (see FIG. 2(a) ) each consisting of a steel pipe having a slit 3a and another type of members (see FIG. 2 (b) ) each consisting of angles 43 which are so combined together that there is formed a slit 43 therebetween, as shown in FIG. 2 .
  • the steel sheet pile is not particularly limited in shape, and thus may be of a type adaptable to be fitted into the connecting members of the steel pipe sheet piles 1, such as hat-shaped steel sheet piles 2 (see FIG. 3(a) ), straight-shaped steel sheet piles 12 (see FIG. 3(b) ), U-shaped steel sheet piles 22 (see FIG. 3(c) ) and Z-shaped steel sheet piles 32 (see FIG. 3(d) ).
  • the hat-shaped steel sheet piles 2 whose arm sections at the sides of joint sections 2b, 2c have flat sections (or flat parts 2a) are not only more easily adaptable to provide setting of the play u with respect to the elongation or shrinkage due to driving at the time of construction of the steel pipe sheet piles but also more excellent in constructability, as compared with the usually available U-shaped steel sheet piles 22 (see FIG. 3(c) ).
  • connecting members 3 will now be described by taking the structure (so with that in FIG. 3 (a) ) shown in FIG. 1 as one instance.
  • the connecting member 3 whose diameter is too small, if employed, makes it hard to be fitted into the steel sheet pile 2. It is thus preferable that the connecting member 3 is not less than 70 mm in inner diameter.
  • the connecting member 3 is not more than 270 mm in outer diameter from the viewpoint of constructability.
  • Yield strength of the wall structure shown in FIG. 1 is determined depending on either yielding of the steel sheet pile 2 or deformation (see FIG. 10 ) of the connecting member 3. That is, when either the steel sheet pile or the connecting member undergoes yielding or deformation, the other will have some margin in view of strength. Accordingly, it may be considered that the requirement (or the form) under which the yielding and the deformation as described the above occur at the approximately same time are the most efficient requirement. Such requirement will now be described with use of some calculation instances.
  • FIG. 11 there are shown the results obtained by numerical analysis on the relation between a load P and an outer diameter ⁇ at the time of the occurrence of deformation or behavior on the assumption that the sheet thickness t of the connecting member 3 is fixed at 11 mm, while the outer diameter ⁇ thereof takes values of 100 mm, 125 mm, 165.2 mm and 200 mm.
  • the length L represents, to be exact, a length ranging from a portion where the connecting member 3 and the steel pipe body of the steel pipe sheet pile 1 are fixed together to a portion where the load will work on the slit 3a of the connecting member 3, in which case, examination was made, provided that the length L is equal with the outer diameter of the connecting member 3, for simplification.
  • the actual steel pipe sheet pile 1 is subject to a certain degree of variations in diameter and/or slit width or others such as welding at the time of machining and/or installation of the connecting member 3. It is thus preferable that there is provided a structure which is such that the sheet thickness t of the connecting member 3 is equal to or larger than the sheet thickness at the changing point of gradient, that is, a structure which meets the expression (2).
  • Expression 9 ⁇ ⁇ ⁇ y ⁇ b 3 ⁇ P y ⁇ t 2
  • the steel sheet pile member does not need to have the same length as the steel pipe sheet pile 1, and thus may be smaller in length than the steel pipe sheet pile 1, in other words, may be of length which is not less than the wall height in order to play a wall role in prevention of outward landslides of earth and sand in the rear.
  • the connected wall structure which is such that spaces sufficient to be charged with the cut-off material are provided in the connecting sections for the steel pipe sheet piles 1 and the steel sheet pile 2, and consequently, itmaybe expected that a sufficient cut-off function will be attained, together with the reduced construction cost and less time and/or labor in relation to the cut-off treatments.
  • the connecting section is excavated using a construction method such as water jetting in order to charge the inside thereof with mortar and/or cut-off material. Accordingly, it is thus preferable that the spaces in the connecting sections for the steel pipe sheet piles and the steel sheet pile will be sized to such an extent that excavation by means of water jetting is executable.
  • the connecting members 3 of the steel pipe sheet piles 1 include, as one instance thereof, connecting members of steel pipe type, each of which being such that a usually available steel pipe having a diameter ⁇ of 165. 2 mm has an about 30-mm-long slit 3a as shown in FIG. 2(a) .
  • connecting members of steel pipe type each of which being such that a usually available steel pipe having a diameter ⁇ of 165. 2 mm has an about 30-mm-long slit 3a as shown in FIG. 2(a) .
  • the sufficiently-sized spaces are provided in the connecting sections for the steel pipe sheet piles 1 and the steel sheet pile 2, and consequently, the property of installation by driving is increased, together with workability for the cut-off treatments. In this case, however, it is feared that too large spaces, if provided, will cause the connecting sections to be disengaged at the time of installation by driving.
  • the stopper member 4 in this case is not particularly limited, and thus may be round steels, deformed steel bars, flat steels and the like, or otherwise, members other than the above are also available. Further, the stopper member 4 does not need to be arranged longitudinally over the whole length of the steel sheet pile 2, and thus may be in dispersed arrangement in order to suppress the machining cost and/or the amount of strain occurring in the steel sheet pile 2 at the time of installation of members.
  • FIG. 5 (a) shows one instance where the hat-shaped steel sheet pile 2 is connected to the steel pipe sheet piles in such a manner as to be eccentric therefrom, in which case, the steel sheet pile 2 is so positioned as to be eccentric from the center axis of the steel pipe sheet piles 1 in order to make alignment of the surfaces as of the wall, and consequently, there maybe provided the increased constructability in cases where facing panels are installed on the front surface of the wall.
  • FIG. 5(b) there is shown one instance where the straight-shaped steel sheet pile 12 is connected to the steel pipe sheet piles 1 in such a manner as to be eccentric therefrom.
