Description

本発明は、支柱杭にコンクリートパネルを組合わせたコンクリート組立擁壁に関するものである。 The present invention relates to a concrete assembly retaining wall in which a concrete panel is combined with a pillar pile.

従来、土留め擁壁を施工する方法としては、法面の手前にＨ型鋼を杭として、地中に打ち込んで、ここにコンクリートパネルを挿入して土留を形成する方法がある。更に擬岩パネルによる壁体を形成し、土留め壁とコンクリートパネルとの間に中詰めコンクリートを充填した構造（特許文献１）がある。 Conventionally, as a method for constructing a retaining wall, there is a method in which an H-shaped steel is used as a pile before a slope and driven into the ground, and a concrete panel is inserted therein to form an earth retaining. Furthermore, there is a structure (Patent Document 1) in which a wall body made of pseudo-rock panels is formed and filled concrete is filled between a retaining wall and a concrete panel.

しかしながら、このＨ型鋼を杭として単に地盤に打ち込んだだけであり、ここに取り付けたコンクリートパネルは中詰めコンクリートの型枠に過ぎず、景観が損なわれない擁壁を形成するだけである。 However, this H-shaped steel was simply driven into the ground as a pile, and the concrete panel attached here is only a formwork of filled concrete, and only forms a retaining wall that does not impair the landscape.

また地盤に複数の支持杭を所定間隔で垂設し、コンクリートパネルの一部を肉厚部に形成してその部分に上下方向を向く支持孔を形成し、該支持孔を所定間隔で垂設された各支持杭に挿入して前記コンクリートパネルを所定の高さに積載支持することにより、前記各支持杭と共に一体形成される土留擁壁において、前記支持孔を挿通突出した複数の支持杭の上端部間を横架部材によって連結して積載擁壁の上端を補強するようにした土留擁壁（特許文献２）がある。 In addition, a plurality of support piles are suspended in the ground at a predetermined interval, a part of the concrete panel is formed in a thick part, a support hole is formed in the vertical direction, and the support hole is suspended at a predetermined interval. By inserting and supporting the concrete panel at a predetermined height by inserting into each of the supported piles, a plurality of support piles protruding through the support holes in the retaining wall integrally formed with each of the support piles There is a retaining wall (Patent Document 2) in which upper ends are connected by a horizontal member to reinforce the upper end of the loading retaining wall.

しかしながら、このコンクリートパネルはパネル板の背面に支持孔を設けた肉厚部があり、保管や運搬が面倒であり、しかも支持孔を挿通突出した複数の支持杭の上端部間を鉄筋にＵ字溝を被せてコンクリートを流し込んで連結するので作業性が悪い問題があった。 However, this concrete panel has a thick part with support holes on the back of the panel board, is troublesome to store and transport, and U-shaped between the upper ends of the support piles that protrude through the support holes. There was a problem that workability was poor because the concrete was poured into the groove and connected.

また近年、激化する自然災害により、抑止杭や擁壁など緊急に災害復旧する必要性が増加してきたが、従来のコンクリート組立擁壁では作業に手間が掛かり迅速な復旧ができなかった。 In recent years, due to intensifying natural disasters, the need for emergency restoration such as deterrent piles and retaining walls has increased. However, conventional concrete assembly retaining walls have been labor intensive and cannot be quickly restored.

以下本発明の実施の一形態を図１ないし図８を参照して詳細に説明する。図１はコンクリート組立擁壁を示すもので、図２はこれを分解して示すものである。図において１は支柱杭で、２は地中に埋設した基礎杭で、この上端開口部３に支柱杭１か挿着されている。４はコンクリートパネル、５はコ字形状をなす押え枠である。 Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. FIG. 1 shows a concrete assembly retaining wall, and FIG. 2 shows it exploded. In the figure, 1 is a pillar pile, 2 is a foundation pile buried in the ground, and the pillar pile 1 is inserted into the upper end opening 3. 4 is a concrete panel, and 5 is a presser frame having a U-shape.

前記支柱杭１は角パイプ７の対向する角の縦方向に沿ってフランジ部８が突設されている。また前記基礎杭２は、図３に示すように、鋼管１０の杭先１１を開口し、この杭先開口部１２に図４に示すように、略菱形の五角形状をなす３個の掘削刃１３が１２０度間隔で鋼管１０の内側から外側に跨がって等間隔で、且つ半径方向に対して鋼管１０の回転方向と反対側に傾斜して取付けられている。この掘削刃１３の傾斜角度αは５〜４０度で傾斜して取付けられている。 The pillar pile 1 has a flange portion 8 projecting along the vertical direction of the opposite corner of the square pipe 7. Further, as shown in FIG. 3, the foundation pile 2 opens a pile tip 11 of the steel pipe 10, and three piled cutting blades having a substantially rhombic pentagon shape as shown in FIG. 4 at the pile tip opening 12. 13 are attached at an interval of 120 degrees, extending from the inside to the outside of the steel pipe 10 at equal intervals, and inclined to the opposite side of the rotation direction of the steel pipe 10 with respect to the radial direction. The excavation blade 13 is attached with an inclination angle α of 5 to 40 degrees.

更にこの掘削刃１３の先端には鋼管１０の回転方向に沿ってＶ溝１５が形成され、このＶ溝１５が形成された先端面には図４に示すように、鋼管１０の上方、すなわち掘削した掘削土を外周側上方に排出するように傾斜した傾斜面１６が形成されている。この傾斜面１６の傾斜角度は５〜２０度に設定されている。 Further, a V groove 15 is formed at the tip of the excavating blade 13 along the rotation direction of the steel pipe 10, and the tip surface where the V groove 15 is formed is above the steel pipe 10, that is, excavated as shown in FIG. An inclined surface 16 is formed so that the excavated soil is discharged upward on the outer peripheral side. The inclination angle of the inclined surface 16 is set to 5 to 20 degrees.

また各掘削刃１３の鋼管外周部分に連続して、掘削土押上刃１７が鋼管１０の先端側外周に縦方向に沿って鋼管１０の回転方向と反対側に傾斜して突設されている。この掘削土押上刃１７は掘削刃１３で掘削した掘削土を上方に押上げると共に、孔内壁に圧密させる作用をなすものである。 Further, continuously from the outer peripheral portion of each of the excavating blades 13, the excavating earth lifting blade 17 is provided on the outer periphery on the tip side of the steel pipe 10 along the vertical direction so as to incline toward the opposite side of the rotating direction of the steel pipe 10. The excavated soil push-up blade 17 serves to push up the excavated soil excavated by the excavating blade 13 and to compact the bored inner wall.

掘削刃１３の取付け方法は、鋼管１０の杭先開口部１２に、間隔をおいて３個のＶ形の切欠部１８を形成し、ここに別に製作した掘削刃１３を嵌入して周囲を溶接して一体にすることにより基礎杭１を作成することができる。 The excavating blade 13 is attached by forming three V-shaped cutouts 18 at intervals in the pile tip opening 12 of the steel pipe 10 and inserting the excavating blade 13 separately manufactured therein to weld the periphery. And the foundation pile 1 can be created by uniting.

また前記コンクリートパネル４は、図２に示すようにコンクリートパネル１９の左右両側に平面Ｙ形状の縦溝９が形成され、このコンクリートパネル１９の上面の長手方向に沿って凹部２０が形成されている。更にこのコンクリートパネル１９の、底面の長手方向に沿って凸部２１が形成されて、これら複数枚のコンクリートパネル４を積み重ねた時に、凸部２１と凹部２０が嵌合して数図１に示すように一体に連結するようになっている。またコンクリートパネル１９の、上面と底面の長手方向に沿って角部は斜めに面取りされている。 Further, as shown in FIG. 2, the concrete panel 4 has planar Y-shaped longitudinal grooves 9 formed on the left and right sides of the concrete panel 19, and a recess 20 is formed along the longitudinal direction of the upper surface of the concrete panel 19. . Furthermore, when the convex part 21 is formed along the longitudinal direction of the bottom face of this concrete panel 19 and these concrete panels 4 are stacked, the convex part 21 and the concave part 20 are fitted and shown in FIG. So that they are connected together. Further, the corners of the concrete panel 19 are chamfered obliquely along the longitudinal direction of the top surface and the bottom surface.

また前記押え枠５はコ字形状をなし、その内幅はコンクリートパネル４の厚さよりやや広く形成されている。また押え枠５の上面中央にはボルト貫通孔２２が開孔されている。なお２３は角パイプ２２の上部に挿着される角ナット、２４はボルトである。なおこれらの部品は全て工場で生産される。 The presser frame 5 is U-shaped, and its inner width is slightly wider than the thickness of the concrete panel 4. A bolt through hole 22 is opened at the center of the upper surface of the presser frame 5. In addition, 23 is a square nut inserted in the upper part of the square pipe 22, and 24 is a volt | bolt. All these parts are produced at the factory.

次にコンクリート組立擁壁の組立方法について説明する。例えば土砂崩れ現場で擁壁を組立てる場合、工場で生産された部品を現場まで運搬する。次に図示しないレッカー車のアームの先端に取付けた油圧オーガーに、基礎杭１を取付けて地面に垂直に支持した状態で、加圧しながら回転させていく。この回転により杭先開口部１２に周方向に沿って等間隔で取付けた３個の掘削刃１３が土２５を回転しながら削っていく。掘削刃１３は杭先開口部１２の内側から外側に跨がって傾斜して取付けられているので、回転しながら食い込むように土２５を削って細かく攪拌する。 Next, a method for assembling the concrete assembly retaining wall will be described. For example, when assembling the retaining wall at the landslide site, the parts produced at the factory are transported to the site. Next, the foundation pile 1 is attached to a hydraulic auger attached to the tip of an arm of a tow truck (not shown) and is rotated while being pressurized in a state where the foundation pile 1 is vertically supported on the ground. By this rotation, the three excavation blades 13 attached to the pile tip opening 12 at equal intervals along the circumferential direction cut the soil 25 while rotating. Since the excavating blade 13 is attached to be inclined from the inside to the outside of the pile tip opening 12, the soil 25 is shaved so as to bite while rotating and finely stirred.

この時、掘削刃１３は鋼管１０の半径方向に対して回転方向と反対側に傾斜角度αで傾斜して取付けられて、しかも掘削刃１３の先端には鋼管１０の回転方向に沿ってＶ溝１５が形成され、更に掘削刃１３の先端は図４に示すように、傾斜面１６が形成されているので、砂層や礫層でも細かく攪拌しながら芯ずれせずに効率よく掘削し、更に掘削した掘削土２６が鋼管１０の外側に効率よく排出されて、鋼管１０の内側に掘削土１２が詰まることなく掘削することができる。 At this time, the excavation blade 13 is attached to the opposite side of the rotation direction with respect to the radial direction of the steel pipe 10 at an inclination angle α, and at the tip of the excavation blade 13 is a V-groove along the rotation direction of the steel pipe 10. 15, and further, the tip of the excavating blade 13 is formed with an inclined surface 16 as shown in FIG. 4, so that even a sand layer or gravel layer can be excavated efficiently without being misaligned while being finely stirred. The excavated soil 26 is efficiently discharged to the outside of the steel pipe 10, and the excavated soil 12 can be excavated without clogging the inside of the steel pipe 10.

更に鋼管１０の外側に送られた掘削土１２は図８に示すように、掘削刃１３に連続する回転方向と反対側に傾斜した掘削土押上刃１７により掘削土１２を速やかに上方に排出し、更に孔２７の内壁に押し付けて圧密する。この結果、鋼管１０の内外の表面に沿った狭い範囲の土２５だけが掘削、攪拌されるので、掘削土１２は鋼管１０内への流入が少なく、詰まることなく摩擦支持力の高い基礎杭１を静かに埋設することができる。 Further, as shown in FIG. 8, the excavated soil 12 sent to the outside of the steel pipe 10 is quickly discharged upward by the excavated soil push-up blade 17 inclined to the opposite side of the rotation direction continuous to the excavated blade 13. Further, it is pressed against the inner wall of the hole 27 for consolidation. As a result, since only a narrow range of soil 25 along the inner and outer surfaces of the steel pipe 10 is excavated and agitated, the excavated soil 12 has a low inflow into the steel pipe 10 and has a high frictional support without clogging. Can be buried quietly.

このように基礎杭２を地中に埋設した後、上端開口部３から支柱杭１を挿入して水平・直垂をとってからコンクリート１９を流し込んで下端側を固定する。このようにコンクリートパネル４の間隔で基礎杭２を埋設して支柱杭１を順次挿着していく。次にレッカー車のクレーンでコンクリートパネル４を吊り上げて、隣接する支柱杭１の間に挿入していく。 After the foundation pile 2 is buried in the ground in this way, the pillar pile 1 is inserted from the upper end opening 3 to take the horizontal / straight suspension, and then the concrete 19 is poured to fix the lower end side. In this manner, the foundation piles 2 are buried at intervals of the concrete panels 4 and the pillar piles 1 are sequentially inserted. Next, the concrete panel 4 is lifted by a crane of a tow truck and inserted between adjacent strut piles 1.

支柱杭１は角パイプ７の対向する角にフランジ部８が突設され、ここがコンクリートパネル４の左右両側に形成した平面Ｙ形状の縦溝９に挿入され、更にこのコンクリートパネル４の上面の凹部２０と底面の凸部２１が嵌合して一体に連結する。また組立てた部分の隙間や面取りされた部分にはモルタル２８やコーキング材を詰めて外観を平滑にする。 The pillar pile 1 is provided with a flange portion 8 projecting at an opposite corner of the square pipe 7, and this is inserted into a plane Y-shaped vertical groove 9 formed on both the left and right sides of the concrete panel 4. The concave portion 20 and the convex portion 21 on the bottom surface are fitted and integrally connected. In addition, the mortar 28 and caulking material are filled in the gaps and chamfered parts of the assembled parts to smooth the appearance.

複数枚のコンクリートパネル４を壁状に組立てたら、図２に示すように支柱杭１の上部に角ナット２３を挿着して固定してから、コ字形状の押え枠５をコンクリートパネル４の上から被せ、ボルト２４をボルト貫通孔２２に通して角ナット２３に取付けて擁壁上部の連結強度を高める。なおこの場合、予め工場で角ナット２３を支柱杭１の上部に溶接しておいたものを用いても良い。 After assembling a plurality of concrete panels 4 into a wall shape, as shown in FIG. 2, a square nut 23 is inserted and fixed to the upper part of the pillar pile 1, and then the U-shaped presser frame 5 is attached to the concrete panel 4. Covering from above, the bolt 24 is passed through the bolt through hole 22 and attached to the square nut 23 to increase the connection strength of the upper part of the retaining wall. In this case, a square nut 23 previously welded to the upper portion of the pillar pile 1 may be used at the factory.

従って本発明のコンクリート組立擁壁は、部品が全て工場で大量生産でき、現場での組立て作業が容易で、安価で擁壁は強度が高く、耐久性に優れ、外観も良好で、自然災害により擁壁施工など緊急な工事に迅速に復旧することができる。 Therefore, the concrete assembly retaining wall of the present invention can be mass-produced at the factory, and the assembly work at the site is easy, inexpensive, the retaining wall has high strength, excellent durability, good appearance, and due to natural disasters. It can be quickly restored to urgent construction such as retaining wall construction.

なお上記説明では凹部２０をコンクリートパネル４の上面に、凸部２１を底面に設けて場合について示したが、この逆でも良い、また基礎杭２として先端開放杭を用いた場合について示したが、先端が閉塞したものや、拡底板を設けたものを用いても良い。 In the above description, the concave portion 20 is provided on the top surface of the concrete panel 4 and the convex portion 21 is provided on the bottom surface, but this may be reversed, and the case where a tip open pile is used as the foundation pile 2 is shown. You may use what closed the front-end | tip or provided the bottom expansion board.

図９は本発明の他の実施の形態を示すもので、従来は（Ａ）に示すように津波遡上対策堤防２９の上に盛土３０を盛ってかさ上げしていたが、本発明では堤防２９の上にコンクリート組立擁壁を設けてかさ上げした場合である。つまり盛土３０は土の運搬や盛り土作業に手間が掛かる上、広い面積も必要になるが、本発明は安価に且つ迅速に津波遡上対策堤防２９のかさ上げをすることができる。 FIG. 9 shows another embodiment of the present invention. Conventionally, as shown in FIG. 9A, the embankment 30 is piled up and raised on the tsunami run-up countermeasure embankment 29. This is a case where a concrete assembly retaining wall is provided on 29 and raised. In other words, the embankment 30 takes time and labor for soil transport and embedding work, and requires a large area, but the present invention can raise the tsunami run-up countermeasure embankment 29 quickly and inexpensively.
