上記特許文献1の擁壁は、H形鋼杭が真っ直ぐに、所定の高さまで打ち込まれていれば良いのであるが、曲がって打ち込まれたり、打ち込み高さ(杭上端高さ)に誤差があると、頭繋ぎ材又は腹起し材を現場溶接を用いて取り付けなければならない。現場溶接は、作業手間、コストがかかるばかりでなく、信頼性にも問題がある。
現実には、H形鋼杭を真っ直ぐに、所定の高さまで打ち込むのはほとんど不可能であるので、頭繋ぎ材又は腹起し材を設けるために作業手間、コストがかかり、信頼性にも欠けるという問題があった。
また、頭繋ぎ材又は腹起し材は擁壁の全長に亘って必要であるので、多くの鋼材を有し、コスト高であるという問題もあった。
本発明は、H形鋼杭が曲がって打ち込まれたり、打ち込み高さ(杭上端高さ)に誤差があっても、容易かつ安価に施工でき、信頼性にも優れた擁壁を開発するためになされたものである。
In the retaining wall of Patent Document 1, it is sufficient that the H-shaped steel pile is driven straight up to a predetermined height. However, the retaining wall is bent and driven or there is an error in the driving height (pile upper end height). And the head tie or bulge must be attached using field welding. In-situ welding is not only labor intensive and costly, but also has problems with reliability.
In reality, it is almost impossible to drive an H-shaped steel pile straight up to a predetermined height, so that it is troublesome and costly to provide a head-connecting material or an uprising material, and lack of reliability. There was a problem.
In addition, since the head tie material or the erection material is necessary over the entire length of the retaining wall, there is a problem in that it has many steel materials and is expensive.
The present invention is to develop a retaining wall that can be constructed easily and inexpensively and has excellent reliability even if the H-shaped steel pile is bent and driven or there is an error in the driving height (pile top height). It was made.
本発明は、
所定間隔で打ち込んだ複数のH形鋼杭と、該H形鋼杭の前面に沿って連続して設けたプレキャストコンクリート製の擁壁パネルとを有し、該擁壁パネルは結合手段によって前記H形鋼杭に結合され、
該結合手段は、前記擁壁パネル背面の所定位置に、先端部に設けられたボルト孔を露出して埋め込まれたアンカーと、後端部にボルト孔を、先端部に雄ねじを有する引張ボルトと、左右両端部にボルト孔を有する受部材とを有し、
前記アンカーと前記引張ボルトの双方のボルト孔を合わせてボルト・ナットで結合し前記引張ボルトを前記擁壁パネルの背面から前記H形鋼杭の面と直角方向に突出配置し、
前記受部材をその左右両端部のボルト孔が前記H形鋼杭の両側に露出するように該H形鋼杭の裏面に配置すると共に、
そのH形鋼杭の両側に露出したボルト孔のそれぞれに前記引張ボルト先端部を挿通してナットで締め付けるものであることを特徴とする擁壁である。
The present invention
A plurality of H-shaped steel piles driven at a predetermined interval; and a retaining wall panel made of precast concrete continuously provided along the front surface of the H-shaped steel pile. Connected to the shape steel pile,
The coupling means includes an anchor embedded in a predetermined position on the rear surface of the retaining wall panel by exposing a bolt hole provided at a front end, a tension bolt having a bolt hole at a rear end and a male screw at a front end. A receiving member having bolt holes at both left and right ends,
The bolt holes of both the anchors and the tension bolts are combined and connected with bolts and nuts, and the tension bolts are arranged so as to protrude from the rear surface of the retaining wall panel in a direction perpendicular to the surface of the H-shaped steel pile.
While arrange | positioning the said receiving member on the back surface of this H-shaped steel pile so that the bolt hole of the right-and-left both ends may be exposed to both sides of the said H-shaped steel pile,
The retaining wall is characterized in that each of the bolt holes exposed on both sides of the H-shaped steel pile is inserted with the tip end portion of the tension bolt and tightened with a nut.
アンカーと引張ボルトの双方のボルト孔を合わせてボルト・ナットで結合し引張ボルトを擁壁パネルの背面から突出配置するとき、引張ボルトの方向はアンカーに対して自由に角度調整できる。このため、H形鋼杭の向きが曲がっていても、引張ボルトを、曲がったH形鋼杭の面と直角方向に突出配置することが可能となる。これにより、引張ボルトを受部材にしっかりと結合でき、擁壁パネルが背面の土圧に対して確実に抵抗できるようになる。   When the bolt holes of both the anchor and the tension bolt are combined and connected with bolts and nuts, and the tension bolt protrudes from the rear surface of the retaining wall panel, the direction of the tension bolt can be freely adjusted with respect to the anchor. For this reason, even if the direction of the H-shaped steel pile is bent, the tensile bolt can be disposed so as to protrude in a direction perpendicular to the surface of the bent H-shaped steel pile. Thereby, the tension bolt can be firmly coupled to the receiving member, and the retaining wall panel can surely resist the earth pressure on the back surface.
本発明において、H形鋼杭を前記擁壁パネルの継目に位置せしめ、前記アンカーを前記擁壁パネルの左右両端部に設けることができる。
このようにすると、1本のH形鋼杭で隣り合う2枚の擁壁パネルのそれぞれの端部を支持できるので、H形鋼杭の数が擁壁パネルの数より1本多い数ですみ、合理的なものとなる。
In the present invention, an H-shaped steel pile can be positioned at the joint of the retaining wall panel, and the anchors can be provided at both left and right ends of the retaining wall panel.
In this way, each end of two retaining wall panels adjacent to each other can be supported by one H-shaped steel pile, so the number of H-shaped steel piles is one more than the number of retaining wall panels. Will be reasonable.
本発明において、前記受部材のボルト孔を、水平方向に長くなっている長穴とすることができる。
このようにすることで、H形鋼杭の向きが著しく曲がっている場合にも対応することができる。
In the present invention, the bolt hole of the receiving member can be a long hole that is elongated in the horizontal direction.
By doing in this way, it can respond also when the direction of an H section steel pile is bent remarkably.
本発明の擁壁は、アンカーと引張ボルトの双方のボルト孔を合わせてボルト・ナットで結合し引張ボルトを擁壁パネルの背面から突出配置するとき、引張ボルトの方向はアンカーに対して自由に角度調整できるので、H形鋼杭の向きが曲がっていても、引張ボルトを、曲がったH形鋼杭の面と直角方向に突出配置し、結合手段でH形鋼杭と擁壁パネルをしっかりと結合することが可能となり、これにより、擁壁パネルが背面の土圧に対して確実に抵抗できるようになる。
また、結合手段は、H形鋼杭の頭部に設ける必要がないので、H形鋼杭の打ち込み高さに誤差があっても問題ない。
さらに、結合手段で使用する鋼材の量は比較的僅かで、現場溶接も必要ないので、低コストで施工でき、信頼性にも優れるものである。
In the retaining wall of the present invention, when the bolt holes of both the anchor and the tension bolt are combined and connected with bolts and nuts, and the tension bolt is disposed so as to protrude from the rear surface of the retaining wall panel, the direction of the tension bolt is free with respect to the anchor. Because the angle can be adjusted, even if the direction of the H-shaped steel pile is bent, the tension bolts are placed in a direction perpendicular to the surface of the bent H-shaped steel pile, and the H-shaped steel pile and the retaining wall panel are firmly connected by the coupling means. This allows the retaining wall panel to reliably resist backside earth pressure.
Moreover, since it is not necessary to provide a coupling means in the head of an H-shaped steel pile, even if there is an error in the driving height of the H-shaped steel pile, there is no problem.
Furthermore, since the amount of steel used for the coupling means is relatively small and no on-site welding is required, construction can be performed at low cost and reliability is excellent.
図1〜4に実施例の擁壁を示す。この擁壁は、H形鋼杭1、擁壁パネル2及び結合手段3からなる。結合手段3はアンカー4(図5)、引張ボルト7(図8)、受部材11(図11)などからなる。   The retaining wall of an Example is shown in FIGS. The retaining wall includes an H-shaped steel pile 1, a retaining wall panel 2, and a coupling means 3. The coupling means 3 includes an anchor 4 (FIG. 5), a tension bolt 7 (FIG. 8), a receiving member 11 (FIG. 11), and the like.
H形鋼杭は、適宜な所定間隔(例えば2m間隔)で、高い方の地盤の土圧に耐えられるように、低い方の地盤面よりも十分深く打ち込まれる。擁壁パネル2はプレキャストコンクリート製で、図1に示すように、H形鋼杭1の前面に沿って連続して設けられる。この場合は、H形鋼杭1が擁壁パネル2の継目2aに位置するようになっている。またこの場合は、擁壁パネル2は捨てコンクリート16の上に支持されているが、このような地業に限らず、例えばH形鋼杭の前面に鉄板、鋼材などの支持材を溶接などで張り出し固定し、その支持材上で擁壁パネルを支持させることもできる。擁壁パネル2の所定位置にはアンカー4が埋め込まれている。この所定位置とは、平面視においてH形鋼杭の両側となる位置で、側面視においては所望の高さに所望の段数設けることができる。この場合は、平面視において擁壁パネル2の左右両端部であり、側面視において上下2段に設けている。   The H-shaped steel pile is driven sufficiently deeper than the lower ground surface at an appropriate predetermined interval (for example, at an interval of 2 m) so as to withstand the earth pressure of the higher ground. The retaining wall panel 2 is made of precast concrete, and is continuously provided along the front surface of the H-shaped steel pile 1 as shown in FIG. In this case, the H-shaped steel pile 1 is located at the joint 2 a of the retaining wall panel 2. Further, in this case, the retaining wall panel 2 is supported on the abandoned concrete 16, but the present invention is not limited to such earth work, and for example, a support material such as an iron plate or steel material is welded to the front surface of the H-shaped steel pile. The retaining wall panel can be supported by overhanging and fixing on the support material. An anchor 4 is embedded in a predetermined position of the retaining wall panel 2. The predetermined position is a position on both sides of the H-shaped steel pile in plan view, and a desired number of steps can be provided at a desired height in side view. In this case, it is the left and right ends of the retaining wall panel 2 in plan view, and is provided in two upper and lower stages in side view.
アンカー4は、図5に示すように、金属(鉄)製の板状部材で、先端部に上下方向に貫通するボルト穴5を有し、後端部は碇着部6となっており、図4に示すように、後端部の碇着部6が擁壁パネル2に埋め込まれ、先端部のボルト穴5が擁壁パネル2の背面に露出している。なお、図5において、上段は平面、下段は側面を示している。後端部の碇着部6は、軸方向に沿って中央に切り込みが入れられ、その両側部分が上下反対方向に曲げられている。これにより、アンカー4に引張力が生じた場合アンカーが擁壁パネルから抜け難いようになっている。   As shown in FIG. 5, the anchor 4 is a plate member made of metal (iron), has a bolt hole 5 penetrating in the vertical direction at the front end portion, and the rear end portion is a brace portion 6. As shown in FIG. 4, the brace 6 at the rear end is embedded in the retaining wall panel 2, and the bolt hole 5 at the distal end is exposed on the back surface of the retaining wall panel 2. In FIG. 5, the upper stage shows a plane, and the lower stage shows a side surface. The rear end portion of the attachment portion 6 is cut in the center along the axial direction, and both side portions thereof are bent in opposite directions. Thereby, when a tensile force is generated in the anchor 4, the anchor is difficult to come off from the retaining wall panel.
図6、7にアンカーの他例を示す。図6は上段に平面、下段に側面を示し、図7は平面を示している。図6のアンカー4は金属製の板状部材で、先端部にボルト穴5を有し、後端部は碇着部6となっている。碇着部6は丸棒を軸線と直角方向に溶接したもので、これによりアンカーが擁壁パネルから抜け難くなっている。図7のアンカー4は金属製の棒状部材(丸棒)で、先端部にボルト穴5を有し、後端部は碇着部6となっている。ボルト穴5は丸棒の先端を丸環状に加工したもので、碇着部6は丸棒の後端を軸線と直角方向に曲げて形成している。
このように、本発明におけるアンカーは、先端部にボルト孔を有し、擁壁パネルから抜け難いものであればよい。
6 and 7 show other examples of anchors. 6 shows a plane in the upper stage, a side surface in the lower stage, and FIG. 7 shows a plane. The anchor 4 in FIG. 6 is a metal plate-like member, has a bolt hole 5 at the front end portion, and has a fastening portion 6 at the rear end portion. The anchoring portion 6 is formed by welding a round bar in a direction perpendicular to the axis, thereby making it difficult for the anchor to come off the retaining wall panel. The anchor 4 in FIG. 7 is a metal rod-like member (round bar), which has a bolt hole 5 at the tip, and a butt portion 6 at the rear end. The bolt hole 5 is formed by processing the front end of a round bar into a round ring shape, and the fitting portion 6 is formed by bending the rear end of the round bar in a direction perpendicular to the axis.
Thus, the anchor in this invention should just have a bolt hole in a front-end | tip part, and should be hard to come off from a retaining wall panel.
アンカー4には、図2、4に示すように、引張ボルト7が取り付けられる。図8(上段が平面、下段が側面、先端部側は省略)に示すように、引張ボルト7の後端部8は、ボルト本体の後端に2枚の板状部材を上下から挟み込むようにして溶接固定したもので、これら2枚の板状部材には上下方向に貫通するボルト孔9が同じ位置に設けられている。アンカー4のボルト孔5と、引張ボルト7のボルト孔9を合わせ、ボルト13をこれらボルト孔に挿入し、ナット14で締め付けてアンカー4と引張ボルト7を結合する。この際、アンカーの軸線と引張ボルトの軸線は自由に傾けて結合することができるので、図2のようにH形鋼杭が曲がって打ち込まれた場合でも、引張ボルトの軸線をH形鋼杭の面1aに直角になるようにすることができる。
引張ボルト7の先端部10には雄ねじが形成されているが、雄ねじは引張ボルトの全長に亘って形成してもよい。
As shown in FIGS. 2 and 4, a tension bolt 7 is attached to the anchor 4. As shown in FIG. 8 (the upper portion is a plane, the lower portion is a side surface, and the tip portion side is omitted), the rear end portion 8 of the tension bolt 7 sandwiches two plate-like members from above and below at the rear end of the bolt body. These two plate-like members are provided with bolt holes 9 penetrating in the vertical direction at the same position. The bolt hole 5 of the anchor 4 and the bolt hole 9 of the tension bolt 7 are aligned, the bolt 13 is inserted into these bolt holes, and tightened with a nut 14 to join the anchor 4 and the tension bolt 7 together. At this time, since the axis of the anchor and the axis of the tension bolt can be freely tilted and coupled, even if the H-shaped steel pile is bent and driven as shown in FIG. It can be made to be perpendicular to the surface 1a.
Although a male screw is formed at the tip 10 of the tension bolt 7, the male screw may be formed over the entire length of the tension bolt.
図9、10に引張ボルトの他例を示す。図9は上段に平面、下段に側面を示し、図10は平面を示しており、全て先端部側は省略している。図9の引張ボルト7の後端部8は、ボルト本体の後端に1枚の板状部材を下から溶接固定したもので、この板状部材には上下方向に貫通するボルト孔9が設けられている。図10の引張ボルト7の後端部8は、ボルトの後端を丸環状に加工し、上下方向に貫通するボルト孔9を形成している。
このように、本発明における引張ボルトは、その後端に種々の方法によってボルト孔を設けることができる。
9 and 10 show other examples of tension bolts. FIG. 9 shows a plane on the upper stage, a side surface on the lower stage, and FIG. 10 shows a plane, with the tip end side omitted. The rear end 8 of the tension bolt 7 in FIG. 9 is obtained by welding and fixing a single plate-like member from the bottom to the rear end of the bolt body, and this plate-like member is provided with a bolt hole 9 penetrating in the vertical direction. It has been. The rear end portion 8 of the tension bolt 7 in FIG. 10 has a bolt hole 9 penetrating in the vertical direction by processing the rear end of the bolt into a circular ring shape.
Thus, the tension bolt in the present invention can be provided with a bolt hole by various methods at the rear end.
図2に示すように、受部材11(図11)を、その左右両端部のボルト孔12がH形鋼杭1の左右両側に露出するようにH形鋼杭1の裏面に配置すると共に、そのH形鋼杭1の両側に露出したボルト孔12の各々に、引張ボルト先端部10を挿通し、ナット15で締め付ける。これにより、擁壁パネル2は背面方向に引っ張られ、背面に作用する高い方の地盤の土圧に対抗することができる。引張ボルト7の軸線はH形鋼杭1の面1aに直角であるので、受部材11の軸線とも直角となり、引張ボルト7と受部材11をしっかりと固定でき、確実に土圧に対抗することができる。
この場合、図11に示すように、受部材11はL形鋼(いわゆる「アングル」)で、その垂直面の両端部に、水平方向に長くなっている長穴であるボルト孔12が水平方向に貫通して設けられている。なお、図11において、左側は正面、右側はボルト孔12部分の断面を示している。
As shown in FIG. 2, while arrange | positioning the receiving member 11 (FIG. 11) on the back surface of the H-shaped steel pile 1 so that the bolt hole 12 of the right-and-left both ends may be exposed to the right-and-left both sides of the H-shaped steel pile 1, Tensile bolt tips 10 are inserted into the bolt holes 12 exposed on both sides of the H-shaped steel pile 1 and tightened with nuts 15. Thereby, the retaining wall panel 2 is pulled in the back direction, and can resist the earth pressure of the higher ground acting on the back surface. Since the axis of the tensile bolt 7 is perpendicular to the surface 1a of the H-shaped steel pile 1, it is also perpendicular to the axis of the receiving member 11, so that the tensile bolt 7 and the receiving member 11 can be firmly fixed and reliably resist earth pressure. Can do.
In this case, as shown in FIG. 11, the receiving member 11 is L-shaped steel (so-called “angle”), and bolt holes 12, which are elongated holes extending in the horizontal direction, are provided at both ends of the vertical surface in the horizontal direction. It is provided to penetrate through. In FIG. 11, the left side is a front view, and the right side is a cross section of a bolt hole 12 portion.
図12に受部材の他例を示す。同図においても、左側は正面、右側はボルト孔12部分の断面を示している。この受板材11はコ字形鋼(いわゆる「チャンネル」で、その垂直面の両端部に、水平方向に長くなっている長穴であるボルト孔12が水平方向に貫通して設けられている。このように、受部材は水平方向に貫通するボルト孔を設けることができ、かつ引張ボルトに作用する引張力を支えることができるものであればどのようなものでもよいが、L形鋼、コ字形鋼、H形鋼、I形鋼などの鋼材とするのが最も適当である。   FIG. 12 shows another example of the receiving member. Also in this figure, the left side is a front view, and the right side is a cross section of the bolt hole 12 portion. The receiving plate material 11 is U-shaped steel (so-called “channel”), and bolt holes 12, which are elongated holes extending in the horizontal direction, are provided through both ends of the vertical surface in the horizontal direction. Thus, the receiving member may be any member as long as it can be provided with a bolt hole penetrating in the horizontal direction and can support the tensile force acting on the tensile bolt. It is most appropriate to use steel materials such as steel, H-shaped steel, and I-shaped steel.
擁壁パネル2の裏側には、高い方の地盤の土砂が埋め戻されるので、図2〜4のように、擁壁パネル背面とH形鋼杭前面の間に隙間があっても、その隙間には土砂が充填され、擁壁パネルが背面側に変位するおそれはないが、場合によっては、擁壁パネル背面とH形鋼杭前面の隙間に、適当なパッキンを設けることもできる。パッキンとしては、例えば土嚢袋に未硬化のモルタルやコンクリートを詰めたもの(自在に変形可能)を擁壁パネル背面とH形鋼杭前面の隙間に入れ込んで使用することができる。土嚢袋の内部のモルタルなどが硬化することでパッキンとして作用し、擁壁パネルが背面側に変位するのが完全に防止される。   Since the earth and sand of the higher ground is backfilled on the back side of the retaining wall panel 2, even if there is a gap between the rear surface of the retaining wall panel and the front surface of the H-shaped steel pile as shown in FIGS. Is filled with earth and sand, and there is no possibility that the retaining wall panel is displaced to the back side, but depending on the case, an appropriate packing can be provided in the gap between the rear surface of the retaining wall panel and the front surface of the H-shaped steel pile. As the packing, for example, a sandbag filled with uncured mortar or concrete (which can be freely deformed) can be used by inserting it into the gap between the retaining wall panel back surface and the H-shaped steel pile front surface. The mortar inside the sandbag is cured and acts as a packing, and the retaining wall panel is completely prevented from being displaced to the back side.
