Description

  The present invention relates to a steel sheet pile joint, and more particularly to an improvement in a joint that can be expanded and contracted and deformed following the displacement of a steel sheet pile accompanying ground fluctuations. The present invention also relates to a method for constructing this improved joint.

  Steel sheet piles are constructed by connecting the joints at both ends of the sheet piles and placing them in the ground to form a steel sheet pile wall to be connected. Widely used throughout construction works such as retaining walls, water barriers, and dikes.

  When ground displacement due to an earthquake occurs, the steel sheet pile does not expand / contract in the connecting lateral direction, and does not deform flexibly, so there is a risk of disengagement of the steel sheet pile or destruction of the steel sheet pile. Therefore, the present applicant previously proposed a steel sheet pile joint described in Patent Document 1. As shown in FIG. 8, this joint has a shape in which a steel sheet pile is halved, and has a plate-like base portion b, a rising portion c rising from the base portion at a predetermined angle, and a tip portion of the rising portion. A pair of plate-like parts a, a composed of joint joints d with adjacent steel sheet piles arranged continuously are aligned on a line with each base being spaced apart and each rising part c is aligned. Arranged so as to be located on the same side of the base b, and the rising part of each base so as to straddle the pair of bases b and b in a state where the flexible water-stopping member e made of rubber or synthetic resin is folded The steel-made flexible water-stopping member protection plates g and h that cover the flexible water-stopping member are fixed to the side where c is located by the flexible water-stopping member fixing metal fitting f, and the pair of plate-like portions a and a. It is arranged on both sides.

According to this joint, since the flexible water blocking member e is disposed in a folded state, the thickness thereof is remarkably reduced compared to a conventional joint in which the flexible water blocking member bulges to one side or both sides of the base. The thickness at the time of placing the protective plates g, h and the flexible water-stopping member e, and thus the cross-sectional area at the time of placement, can be significantly reduced, thereby easily placing the joint. There is an advantage that you can.
JP 2003-049421 A

  In the conventional steel sheet pile joint, since the steel protective plates g and h are welded to either one of the pair of plate-like portions a and a, the plate-like portions a and a approach each other. In the case of displacement in the separating direction, the relative displacement between the pair of plate-like portions is possible, but the pair of plate-like portions a and a are deformed in a bending direction at an angle from the normal alignment position. When an external force is applied, the protective plate cannot be easily removed due to a relatively large resistance (about 30 kN) due to the welding of the protective plate. The member is prevented from being sufficiently deformed, and the relative displacement absorbing function is impaired. As a result, the connection between the steel sheet pile joint and the steel sheet pile may be broken. For this reason, when actually constructing the above-mentioned conventional joint, the protective plate is temporarily welded to the joint plate-like portion by temporarily welding the protective plate and applying an impact with a bi-pro hammer after the completion of driving the joint. As a result, the joint construction process increases and the construction cost increases.

  The present invention has been made in view of the problems of the above-described conventional steel sheet pile joints, and does not require temporary welding of the protective plate, and is an improved steel sheet pile joint that solves the above-described problems of the prior art. And to provide the construction method.

  The steel sheet pile joint according to claim 1, which achieves the object of the present invention, has a shape in which the steel sheet pile is halved, a plate-like base portion, a rising portion rising from the base portion at a predetermined angle, A pair of plate-like parts composed of jointed joints with adjacent steel sheet piles arranged continuously at the tip of the rising part are aligned on a line with each base part being spaced apart, and each rising part is aligned. Placed on the same side of the base, and flexible water-stopping members made of rubber, synthetic resin, etc. across the pair of bases and flexible on the side where the rising part of each base is located A cover sheet made of a material that is fixed by a water-stop member fixing means and is not easily damaged by contact with the ground on which the joint is placed is covered with the folded portion of the flexible water-stop member. Are arranged on both sides of the part, and when a predetermined force is applied, the relative displacement between the pair of plate-like parts is So as to volume, characterized in that fixed to at least one of the movable Shiwatome water member fixing means and movable Shiwatome water members.

  In the joint according to claim 2, the cover sheet is made of a polyolefin elastomer or polyethylene.

  4. The joint according to claim 3, wherein the flexible water blocking member fixing means is a pair of fixing protrusions continuous in the longitudinal direction formed by raising one side of both ends in the width direction of the flexible water blocking member. And a plate-like fastening portion welded to the base of the plate-like portion, and rises from the fastening portion and extends inward in the width direction of the flexible water-stopping member over the fixing protrusion of the flexible water-stopping member A pair of flexible water-stopping member fixing metal fittings each having a pressing portion to perform, and the flexible water-proofing member fixing metal fittings and the flexible water-proofing member on the inner side in the width direction of the flexible water-proofing member from the fixing protrusion The cover sheet has a pressing plate disposed between the pressing plate of the flexible waterproofing member fixing means and the flexible waterproofing member or at the base portion thereof. The flexible water blocking member fixing means is fixed by being sandwiched between the flexible water blocking members.

  5. The joint according to claim 4, wherein a part of the cover sheet is adhered to at least one of the flexible waterproof member fixing bracket or the flexible waterproof member of the flexible waterproof member fixing means with an adhesive. It is characterized by.

  The method for constructing a steel sheet pile joint according to claim 5 comprises a pair of plate-like parts having a base, a rising part and a joint joint part having the same shape as the steel sheet pile joint according to claim 1, the overall width of which is the joint. Are arranged with a predetermined interval between the plate-like portions so as to be equal to the width of the plate, and arranged with a predetermined interval in the longitudinal direction of the plate-like portions so as to straddle the pair of plate-like portions. A guide sheet pile for a joint formed by fixing the width determining material to each plate-like portion, and after placing a steel sheet pile on one side of the steel sheet pile connected by the joint of the steel sheet pile, the joint guide The steel sheet on the other side connected by the joint of the steel sheet piles, in which the joint sheet pile of the steel sheet piles is driven so that one joint part of the sheet piles is joined to the adjacent joint joint part of the one steel sheet pile Placing the sheet pile so that one of the joint joints is joined to the other joint joint of the joint guide sheet pile The steel sheet pile for the joint is pulled out after the steel sheet pile adjacent to the other side is sequentially placed, and then the joint of the steel sheet pile is joined by the joint joint portion of the steel sheet pile on the one side. And the other joint joint portion is placed so as to be joined to the adjacent joint joint portion of the other steel sheet pile.

  According to the invention of claim 1, a cover sheet made of a material that is not easily damaged by contact with the ground on which the joint is placed is used instead of the steel protective plate, and a predetermined force is applied to the cover sheet. In some cases, since the relative displacement between the pair of plate-like portions is allowed to be fixed to at least one of the flexible waterproofing member fixing means and the flexible waterproofing member, the temporary welding of the protective plate is forcibly destroyed. This process becomes unnecessary, the construction of the steel sheet pile is simplified, and the construction cost can be reduced.

  According to the second aspect of the present invention, the use of a polyolefin elastomer or polyethylene, which is particularly excellent in the property of being hard to be damaged by contact with the ground as compared with other synthetic rubber and synthetic resin, is used as the cover sheet. It is possible to sufficiently prevent the flexible waterstop member from being damaged during installation.

  According to the third aspect of the present invention, the cover sheet is sandwiched at one end in the width direction between the press plate of the flexible waterproof member fixing means and the flexible waterproof member or between the base and the flexible waterproof member. Therefore, when a large force acts on the plate-like portion due to ground subsidence or the like, relative displacement between the plate-like portions is easily allowed.

  According to the fourth aspect of the present invention, a part of the cover sheet is bonded to at least one of the flexible water-stopping member fixing bracket and the flexible water-stopping member of the flexible waterstop member fixing means with an adhesive. Therefore, when a large force is applied to the plate-like portion due to ground subsidence or the like, the synthetic resin sheet easily allows the relative displacement between the plate-like portions by peeling off and separating.

  The invention of claim 5 relates to a method for easily constructing the steel sheet pile joint of claim 1. In a conventional steel sheet pile joint, since the steel protective plate is temporarily welded to the joint before the joint is placed, the steel protective plate regulates the position of the soil portion when the joint is placed. The pair of plate-like portions are prevented from being bent and driven at an angle from the original alignment position. However, in the joint according to claim 1, since the steel protective plate is not used, a pair of plate-like portions is used. There is a possibility that the part is bent and driven from the original alignment position.

  According to invention of Claim 5, after placing the steel sheet pile on one side to be connected by the steel sheet pile joint, the guide sheet pile for the joint is placed, and the other side to be connected by the steel sheet pile joint. The steel sheet pile is placed so as to be joined to the joint guide sheet pile, and then the joint sheet pile is pulled out and the steel sheet pile joint is subsequently placed. It is possible to prevent the joint from being bent and driven by being regulated by the steel sheet piles on both sides, so that the joint can be constructed smoothly and easily.

Embodiments of the present invention will be described below with reference to the accompanying drawings.
FIG. 1 is a sectional view showing one embodiment of a steel sheet pile joint according to the present invention, and FIG. 2 (a) is a front view of the embodiment.

  A steel sheet pile joint 1 according to an embodiment of the present invention has a shape obtained by halving a U-shaped steel sheet pile, a plate-like base portion 3, a rising portion 4 rising from the base portion 3 at a predetermined angle, and a rising portion. A pair of plate-like portions 2 each consisting of a jointed joint portion 5 with an adjacent steel sheet pile connected to the tip end portion of 4 are aligned with each base portion 3 at a predetermined interval and each rising portion 4 is aligned. Are arranged on the same side of the aligned base 3 and a pair of long strip-shaped flexible water-stopping members 6 made of rubber, synthetic resin or the like are folded in the center 6a in a pair. The base 3 is fixed to the side where the rising portion 4 of each base 3 is located by the flexible water-stopping member fixing means 7.

  In the present embodiment, the flexible waterproofing member 6 is formed with a pair of fixing protrusions 6c that are continuous in the longitudinal direction by raising one side of the widthwise both ends 6b. The pair of flexible water-stopping member fixing means 7 includes the fixing protrusion 6c, the plate-like fastening portion 8a welded to the base portion 3 of the plate-like portion, and the flexible water-stopping member 6 rising from the fastening portion. Possible from a pair of steel flexible water blocking member fixing metal fittings 8 provided with a pressing portion 8b extending beyond the fixing protrusion 6c inward in the width direction of the flexible water blocking member 6, and the fixing protrusion 6c. The presser plate 9 is disposed between the pressing portion 8 b of the flexible waterstop member fixing bracket 8 and the flexible waterstop member 6 on the inner side in the width direction of the flexure waterstop member 6. As shown in FIG. 2, the flexible water-stop member fixing metal fitting 8 is welded to the base 3 at a predetermined interval in the longitudinal direction of the joint.

  The fixing protrusion 6c of the flexible water stop member 6 is disposed between the pressing portion 8b of the flexible water stop member fixing bracket 8 and the substrate 3, and the presser plate 9 extends from the fixing protrusion 6c to the flexible water stop member 6. The fastening portion 8a of the fixing bracket 8 is welded to the base portion 3 while being disposed between the pressing portion 8b and the flexible water-stopping member 6 on the inner side in the width direction. The part 8 b presses and fixes the both end parts 6 b of the flexible water-stopping member 6 to the base part 3 via the pressing plate 9.

  In the conventional steel sheet pile joint shown in FIG. 8, the flexible water stop member e is pressed against the base b by the flexible water stop member press fitting f, and the press fitting f is fixed to the base b by the bolt i. However, in order to fasten the bolts, the base b and the presser fitting f must be drilled with bolt holes corresponding to the number of bolts. In addition to the problem that the construction cost is increased, there is a problem that water leakage may occur from these bolt holes, and there is a problem that careful water stop measures are required, but according to this embodiment, Since the flexible waterproofing member fixing bracket of the flexible waterproofing member fixing means is fixed to the base by welding rather than bolting, it is not necessary to drill a large number of bolt holes in the base and the fixing bracket, and the construction is simplified. Not only It is advantageous in that a risk that water leakage from the holes becomes necessary to apply a time and cost without waterproofing measures eliminated. However, the present invention can be applied not only to the case where the fixing bracket is welded as described above but also to the case where the fixing bracket is fixed by bolting.

  In the lower part (the part below the line showing part omission in FIG. 2) placed in the middle of the joint, there are joints on the side where the rising part 4 of the plate-like part 2 rises and on the opposite side. Cover sheets 10 and 11 made of a polyolefin elastomer or polyethylene, which is a material that is not easily damaged by contact with the ground on which the resin is placed, are disposed so as to cover the folded portion 6 a of the flexible water-stopping member 6. ing. One end 10a in the width direction of the cover sheet 10 on the side where the rising portion 4 rises is fixed to the flexible waterproof member fixing means 7 by being sandwiched between the holding plate 9 and the end portion 6b of the flexible waterproof member 6. ing. Moreover, the width direction other end part 10b of the cover sheet 10 is made into a free end, and the part 6a folded so as to wind one end part in the width direction of the folded part 6a of the flexible water blocking member 6; It is inserted into the space between the presser plates 9.

  One end portion 11 a in the width direction of the cover sheet 11 on the opposite side is fixed to the flexible waterproof member fixing means 7 by being sandwiched between the base portion 3 and the end portion 6 b of the flexible waterproof member 6. Moreover, the width direction other end part 11b of the cover sheet 11 is made into a free end, and the part 6a folded so that the width direction other end part of the folded part 6a of the flexible water blocking member 6 may be wound. And the end 6b.

  When using a synthetic resin sheet as the cover sheet, in addition to the above materials, vinyl chloride can be used. Polyolefin elastomers and polyethylene have a higher tensile strength than vinyl chloride and other resins. It is the most suitable material because it has high elongation and tear strength, is unlikely to deteriorate over time in the ground, and has low temperature dependence that makes it hard or soft depending on the temperature during handling, so it is easy to handle. . The thickness of the cover sheet is preferably about 1.5 mm to 2.0 mm. In addition to the sheet of the above material, a polycarbonate plate or a steel plate can also be used.

  According to this structure, since the flexible water-stop member 6 and the cover sheets 10 and 11 form substantially the same surface as the outer surface of the steel sheet pile row, a guide beam in which a pair of H steels are arranged in parallel is installed. When this guide beam is used as a ruler and a steel sheet pile is driven in a straight line between them, the joint does not become an obstacle, and the construction can be performed easily.

  In the embodiment of FIG. 1, only one end of each of the cover sheets 10 and 11 is sandwiched and the other end is a free end, but not limited thereto, for example, both ends of each cover sheet are sandwiched and fixed, You may make it accept | permit the relative displacement between a pair of plate-shaped parts by giving the longitudinal cut line which cut | disconnects in the center part of the width direction of a cover sheet, when predetermined | prescribed tensile force acts.

  2 (a) and 2 (b), a tip flange 15 is attached to the lower end of the base 3. When the joint is driven by projecting the joint rod 19 from the joint portion 19 which is welded and fixed to the base portion 3 on the left side in the drawing and the folded portion 6a of the flexible water blocking member 6 Are integrally provided with a flexible waterproofing member protecting part 20 for protecting the flexible waterproofing member 6.
