Definitions

  • the present invention relates to steel sheet piles for use in civil engineering and building construction, as well as to processes for the production thereof including a hot rolling step. More particularly, the invention is concerned with steel sheet piles in which the joints on the right- and left-hand sides are asymmetrical (such steel sheet piles being hereinafter referred to as asymmetrical steel sheet piles) as well as processes for their production.
  • the present invention also relates to corner steel sheet piles which are used to make the corners of a steel sheet pile wall, as well as to processes for their production.
  • Figure 1 is a schematic cross-sectional view of an asymmetric U-shaped steel sheet disclosed in that Japanese patent application.
  • steel sheet pile 1 has flange portions 2, a web portion 3, and asymmetrical joints 4, 5 at opposite ends having different shapes from each other.
  • FIG 2a schematically illustrates a wall, which serves as a retaining wall, for example, constructed by joining such asymmetrical steel sheet piles 1 close to the adjacent land (A.L.).
  • a wall shown in Figure 2b which is formed by conventional symmetric steel sheet piles 6, the asymmetrical steel sheet piles achieve more efficient use of space, since the required working area (W.A.) shown by a dashed line in Figure 2a is smaller than that in Figure 2b.
  • the working area (W.A.) indicates the minimum working area required to perform field installation of sheet piles by means of a pile hammer.
  • the thickness (D 1 ) of the wall composed of the asymmetric sheet piles 1 shown in Figure 2a is much smaller than that (D 2 ) of the wall formed by the conventional symmetric sheet piles 6 shown in Figure 2b.
  • the above-described asymmetrical U-shaped steel sheet piles make it possible to pile them consecutively to form a wall since they are arranged in series in the same direction.
  • the resulting wall has a section stiffness comparable to or higher than that of a wall of conventional symmetric U-shaped steel sheet piles.
  • FR-A-664775 discloses an asymmetric steel sheet pile having two joints one facing outwardly and the other inwardly. In order to be able to connect the piles the joints are fixed to the main member by short arm portions.
  • a corner When a corner is to be formed in a retaining wall using conventional symmetric U-shaped steel sheet piles, a special steel sheet pile having a different shape must be used to change the direction of the U-shaped sheet pile wall.
  • a steel sheet pile for forming a corner will be referred to as a corner (steel) sheet pile.
  • corner steel sheet piles for use with conventional U-shaped steel sheet piles are disclosed, for example, in Japanese Patent Publications Nos. 64-8139(1989), 2-60807(1990), and 6-9682(1994). Processes for producing corner steel sheet piles are disclosed in Japanese Patent Publications Nos. 64-10281(1989) and 6-9682(1994).
  • Figures 3a and 4a show examples of corner steel sheet piles which can be used along with conventional U-shaped steel sheet piles.
  • the corner sheet pile shown in Figure 3a (which will be referred to as T-shaped) consists of a U-shaped sheet pile 7 and a half section of a sheet pile of the same U shape which is vertically cut in its web portion and welded to the first full sheet pile with the cut edge abutting on the backside 8 of the web portion of the first sheet pile.
  • the corner sheet pile shown in Figure 4a (which will be referred to as W-shaped) is comprised of a U-shaped sheet pile 7 which is bent along the vertical center line of its web portion 9 and which may be reinforced by build up welding (overlaying) on the inside corner of the bend.
  • Figures 3b and 4b schematically show the manner of joining the corner sheet piles of Figures 3a and 4a, respectively, with U-shaped sheet piles to form a corner.
  • a T-shaped corner sheet pile is roughly 1.5 times as heavy as an ordinary U-shaped sheet pile, and it is difficult to hold with a chuck of a vibro pile hammer, which is commonly used for steel sheet piles. It is also inconvenient for storage and shipping since its shape makes stacking impossible.
  • a W-shaped corner sheet pile has a very small section modulus, even though the above-described build up welding is applied, the section modulus being insufficient to ensure that the resulting cornered wall is safe as a retaining wall.
  • grasping a W-shaped corner sheet pile in the chuck of a pile hammer may be difficult.
  • an asymmetric U-shaped steel pile is manufactured by welding, but a hot rolling process can be employed to produce it.
  • a hot rolling process a conventional process for manufacturing symmetric U-shaped steel piles is repeated except that each of the joints of an asymmetric U-shaped steel pile is formed little by little through a plurality of passes using a plurality of grooved rolls.
  • the processes of forming the pile therefore, takes place in a bilaterally symmetric manner, and grooves for its manufacture are designed to be bilaterally symmetric. This is the case for bending joint portions, too.
  • joints are bent bilaterally simultaneously through passes of rolls having bilateral symmetric grooves.
  • Figures 5a and 5b are grooved rolls (K-2) before finishing and grooved rolls (K-1) for finishing, respectively, each of which comprises an upper roll (U. R.) and a lower roll (L. R.), and which are used for hot rolling a conventional type of bilaterally symmetrical U-shaped steel pile.
  • a rolling material i.e., a U-shaped steel pile 11 comprises bilateral flange portions 10, a web portion 12, and bilateral joints 14.
  • the rolling material is shaped by hot rolling with respect to the thickness and height of joints, and at the stage of Figure 5b the joints are bent to a finished shape by the grooved rolls (K-1).
  • Figure 6 shows the process of bending of joints by the grooved rolls (K-1) in more detail. The process can be divided into the following four steps. In Figure 6, only one widthwise end of the rolling material, i.e., a U-shaped steel pile 11 comprising its flange portion 10, web portion 12, and joint 14 is shown.
  • Step (I') shows the U-shaped steel pile just after leaving the grooved rolls (K-2), and in Step (I), the U-shaped steel pile 11 is subjected to pre-deformation due to contact of the rolling material with a roll at its front edge, resulting in a decrease in the width of the steel pile.
  • the term "width” means that of a full length of width of U-shaped steel pile.
  • step (II) a collar 20 of the upper roll 18a contacts the outer surface of a joint 14, resulting in a decrease in width, and bending is started.
  • Step (III) a lower roll 22 contacts the joint, and in Step (IV) the upper and lower rolls 18, 22 finish bending of the joint 14.
  • Step (IV') shows a finished sheet pile after leaving the rolls (K-1).
  • a rolling material or rolled product is bilaterally asymmetric, and in particular when it has bilaterally asymmetric joints, deformation by bending does not occur bilaterally symmetrically in a section perpendicular to the rolling direction.
  • the position of the rolling material is bilaterally asymmetric and is different between before and after being gripped by rolls, causing a fluctuation in rolling position and incomplete bending of joints.
  • An object of the present invention is to provide an asymmetric steel sheet pile with joints having a bilaterally asymmetric shape in its section, and which can be used to form a wall by inserting the sheet piles into the ground in series, there being no bulges away from the wall at joints between adjoining sheet piles.
  • Another object of the present invention is to provide a process for producing asymmetric steel sheet piles with joints having a bilaterally asymmetric shape in section by hot rolling, in which bending of the joints is carried out without fluctuations in roll bending position and incomplete bending of joints.
  • Still another object of the present invention is to provide a corner steel sheet pile and a process for its production, the corner sheet pile being particularly suitable for joining U-shaped sheet piles having asymmetric joints, and being capable of being grasped by the chuck of a pile hammer as well as being capable of being stacked during storage and shipping.
  • the inventors found that it is possible to join the opposing joints of sheet piles along a line extending from flat arm portions when one bilateral asymmetric joint is arranged downwardly and another one is arranged upwardly, and that the resulting sheet pile wall does not have bulges away from its innermost surface.
  • the present invention has been completed based on the findings that, instead of carrying out bending of bilateral joints simultaneously by a single pass, bending is carried out separately for each of the bilateral joints, and the before-mentioned problems can be solved effectively.
  • the inventors also designed many corner sheet piles for use in connecting the above-mentioned asymmetric sheet piles, and carried out test installation thereof.
  • the inventors completed the present invention, therefore, based on the findings that it is possible to change the direction of a steel pile wall by 90° merely by bending inwardly either one of the joints, without using any specific corner sheet piles such as T-type sheet piles.
  • the present invention provides an asymmetric steel sheet pile as defined by appended claim 1 and a process for producing said pile.
  • Figure 7 is a general view showing an example of a U-shaped steel sheet pile 30 of the asymmetric type according to the present invention
  • Figure 8 shows the joint thereof
  • Figure 9 shows a sheet pile wall 40 which is built by striking a series of asymmetric U-shaped sheet piles into the ground.
  • the asymmetric U-shaped steel sheet pile 30 has a main member having a U-shape, and the main member comprises a web portion 32 and flange portions 34 to form a sheet pile body.
  • Bilateral joints 36, 38 are arranged in an asymmetric manner, e.g., joint 36 is made inward and joint 38 is made outward, so that while the convex portions, i.e., the U-shaped sides are arranged on the same side, the joints can be combined along a line extended from the line connecting the opposite arm portions 37, i.e., they can be combined on the sheet pile wall.
  • arm portions 37 are provided extending in parallel to the alignment line (shown by a three-dot chain line in Figure 7), and the joint portion where the joints 36, 36 are combined is positioned together with the arm portion 37 along the same line as the innermost edge 35 of the sheet pile wall 40 (shown by a one-dot chain line in Figure 7).
  • one joint 38 faces outward and the other joint 36 faces inward with respect to the innermost edge which corresponds to the front edge of excavation.
  • the joints can be combined with each other, as shown in Figure 8, in such a way that there is no protrusion from the inner side of the wall surface of the sheet pile wall 40.
  • the outward joint 38 comprises a ridge portion 39 to prevent the joints from rotating.
  • the asymmetric U-shaped sheet pile 30 when the asymmetric U-shaped sheet pile 30 is sunk into the ground by a hydraulic press or by a vibro pile hammer, it is possible to grasp the arm portion 37 with a chuck as shown in Figure 9. Since the arm portion 37 is positioned in parallel to the alignment line and on the same line as the line on which the joints are positioned, i.e., the connection axis (shown by a two-dot chain line in Figure 7), and the joint portion, which would be the center of rotation if the sheet pile were to rotate during striking into the ground, is located on the same level as the arm portion 37, it is possible to prevent the steel sheet pile 30 from rotating when striking forces are applied to the chuck 44.
  • an asymmetric U-shaped steel sheet pile 30 of the present invention has an arm portion 37 which can exhibit resistance (as shown by black arrows in Figure 9) against a force (shown by a white arrow in Figure 9) tending to rotate the pile, rotation or twisting of the U-shaped sheet pile underground can be prevented.
  • FIG 10a through Figure 10c some examples of grooved rolls for use in producing a bilateral asymmetric U-shaped sheet pile of the present invention are shown, i.e., grooved rolls (K-3') which are used before finish bending, and grooved rolls (K-2' and K-1') for joint bending.
  • grooved rolls (K-3') which are used before finish bending
  • grooved rolls (K-2' and K-1') for joint bending.
  • an asymmetric sheet pile 30 which is prepared by a conventional method of hot rolling with grooved rolls is introduced to grooved rolls K-3' having an upper roll (U.R.) and a lower roll (L. R.) so as to adjust its joint thickness and joint height.
  • grooved rolls K-3' are employed, as shown in Figure 10b, bending of the left-hand side joint, for example, is carried out using grooved rolls K-2' comprising an upper roll (U.R.) and a lower roll (L. R.).
  • the shape of the sheet pile 30 in section perpendicular to the rolling direction is bent in a bilaterally asymmetric manner, and its positions before and during roll bending are different from each other with respect to its bilateral shapes.
  • the right-hand side joint is not subjected to bending, forced deformation can be suppressed near the roll bottom dead center, resulting in a stable rolling position, especially on the exit side.
  • the left-hand side joint is bent successfully, and the shape of the right-hand side joint when just leaving the grooved rolls (K-3') can be maintained.
  • the right-hand side joint is subjected to bending in the grooved rolls (K-1') while the shape of the groove on the left-hand side is designed to be the same as that of the grooved rolls (K-2').
  • the rolling position is stable for the same reason as mentioned before, and, as a whole, bilateral joints each having a good shape can be obtained.
  • the other joint while one joint is being subjected to bending, the other joint may be formed to some extent, i.e., to an intermediate degree of bending. This degree of bending will be referred to as "intermediate bending".
  • intermediate bending means bending carried out in step (II), namely until the tip of the joint is bent upright. Such a degree of bending does not adversely affect the rolling position.
  • intermediate bending corresponds to that carried out by the grooved rolls (K-2') shown in Figure 10b in which bending proceeds to a degree where instability of rolling position remains within a tolerance.
  • the bilateral joints are subjected to bending under conditions that a substantial degree of bending is not applied simultaneously to both joints.
  • the present invention will be described with respect to a corner steel sheet pile and a process for producing it.
  • Figure 11 and Figure 12 illustrate a corner sheet pile 54 of the present invention, which comprises an inward joint 50 and an outward joint 52.
  • Figure 11 is a schematic view of a corner sheet pile 54 in which the inward joint 50 is combined with an arm by welding with an inward inclination at an angle of 45°.
  • Figure 12 is a schematic view of a corner sheet pile 54 in which the outward joint 52 is combined with an arm by welding with an inward inclination at an angle of 45°.
  • a welded portion 56 is indicated in black.
  • a starting asymmetric U-shaped sheet pile for forming the corner sheet pile 54 of the present invention is indicated by reference figure 30 in Figure 7, which comprises one inward joint 36 (facing downwardly) and an outward joint 38 (facing upwardly) with these joints being connected with the neighboring ones in series while arranging the U-shaped portions in the same direction.
  • Figure 7 as well as in Figure 11 and Figure 12, either one of the joints 36, 38 of sheet pile 30 is bent inwardly (downwardly) at an angle of 45° at a border line 55 between a flat arm portion 37 and the joint.
  • the border line 55 is indicated by a dotted line, and this portion also corresponds to a weld portion in case the corner sheet pile is manufactured by welding.
  • Figure 13a illustrates how the corner sheet piles of the present invention, i.e., a corner sheet pile having an inward joint bent inwardly and a corner sheet pile having an outward joint bent inwardly are installed with the corresponding joints of sheet piles being combined.
  • Figure 13b is an enlarged view of a portion of Figure 13a.
  • an inner surface 51a of a contact edge 51 of the inward joint 50 is positioned in parallel to the alignment line (indicated by a two-dot chain line in Figure 11) as well as the connection axis (indicated by a one-dot chain line in Figure 11) of steel sheet pile 54.
  • an inner surface 53a of a contact edge 53 of the outward joint 52 is positioned perpendicularly to the alignment line (indicated by a two-dot chain line in Figure 12) as well as the connection axis (indicated by a one-dot chain line in Figure 12) of steel sheet pile 54.
  • an asymmetric U-shaped steel sheet pile having an inward joint and an outward joint such as shown in Figure 7 can be produced by hot rolling, and either one of the resulting joints is cut at a border line (indicated by the dashed line in Figure 7).
  • the removed joint is turned inwardly, and the resulting joint is welded to the arm portion at the border line where the joint was previously cut.
  • a corner sheet pile merely by bending inwardly either one of the joints of a U-shaped sheet pile having bilateral asymmetrical joints, and such bending can be achieved by hot rolling, or hot or warm forming.
  • Figure 14 shows an example in which an outward joint is bent inwardly by hot rolling to produce a corner sheet pile of the present invention.
  • grooved rolls comprise an upper roll 60 and a lower roll 62, and a rolling material such as pre-shaped sheet pile, e.g., an asymmetric U-shaped steel sheet pile 30 shown in Figure 7, is used. While the upper and lower surfaces of the sheet pile 30 are constrained by the upper and lower rolls 60, 62, an outward joint 38, for example, is pressed downward so as to achieve bending by a single pass. Thus, bending of joint 38 is carried out by inserting the rolling material into the grooved rolls.
  • Figure 15 shows an example in which an inward joint is bent inwardly by hot or warm forming to produce a corner sheet pile of the present invention.
  • an asymmetric U-shaped steel sheet pile 30 shown in Figure 7 is used as a rolling material.
  • Roller guides 64 are positioned at the opposite sides of the steel sheet pile 30. While the upper and lower surfaces of the sheet pile 30 are constrained by the upper and lower rollers 66, 68, and the side of the outward joint 38 is constrained by a roller 70 provided by on the left-hand side, an inward joint 36, for example, is pressed downward by the upper roller 66 provided on the right-hand side so as to achieve bending by a single pass. From the viewpoint of facilitating forming, it is preferable for the forming roller guide 64 to be positioned near and downstream of a rolling machine for hot finishing asymmetric sheet piles 30.
  • the corner sheet piles of the present invention can be installed underground in the same manner as the asymmetric U-shaped sheet pile of the present invention shown in Figure 7.
  • the present invention is free from the troubles encountered by conventional T-shaped or W-shaped corner sheet piles that are impossible for the chuck of a pile hammer to grasp in a usual manner.
  • a bend angle of the sheet pile wall i.e., an angle between the lines of alignment of two series of sheet piles which cross each other, is 90° in most cases, but it may be possible to employ an angle other than 90°, depending on the construction site.
  • a corner sheet pile can be produced by bending either one of the joints with a roller guide provided near or downstream of a finish rolling machine, and by adjusting the bending angle to an appropriate angle other than 90°, a corner sheet pile can be obtained which can be used at a corner having an angle other than 90°.
  • Figures 16a and 16b shows how the corner sheet piles 54 of the present invention are stacked.
  • Figure 16a shows the case in which inward joints are bent inwardly
  • Figure 16b shows the case in which outward joints are bent inwardly.
  • joint portions do not interfere with each other upon stacking, and it is possible to stack a number of sheet piles without resulting in instability of the stack.
  • Figures 17 show results of analysis of a process of forming a rolling material within grooved rolls K-2' (see Figure 10), which was carried out by means of 2D-FEM.
  • the present invention is effective in respect to prevention of galling during rolling of joints.

  • the rolls of each roll mill had 4 grooves, 3 grooves, and 3 grooves, respectively.
  • a rolling material was subjected to reverse rolling through these three rolling mills to finish asymmetric U-shaped sheet piles, as shown in Figure 7.
  • the corner sheet pile was produced by using a roller guide and forming roller to bend outward joints at angle of 45° inwardly to produce corner sheet piles of type A (see Fig. 12), and to bend inward joints at an angle of 45° inwardly to produce corner sheet piles of type B (see Fig. 11).
  • Hot rolled sheet piles were also produced in the same production chance (lot) by expanding the gaps between the roller guides and between rollers.
  • asymmetric U-shaped steel sheet piles which can be arranged such that the joints and flat arm portions are positioned on the same plane corresponding to the innermost edge of a sheet pile wall can be obtained.
  • These asymmetric U-shaped steel sheet piles having bilateral asymmetric joints can be produced by hot rolling which is free from instability of rolling position and imperfect bending of joints, resulting in sheet piles having well-shaped joints.
