以下、本発明の実施形態に係る締固めアタッチメント装置１００及び締固め方法について、図面を参照して説明する。 Hereinafter, the compaction attachment device 100 and the compaction method according to the embodiment of the present invention will be described with reference to the drawings.

図１は、土木構造物１を構築している状態を示す図である。図１に示すように、締固めアタッチメント装置１００及び締固め方法は、コンクリート材料又はＣＳＧ材料で土木構造物１を構築する工事において用いられる。ここでは、土木構造物１がダムにおける堤体の一部である場合について説明するが、土木構造物１は、堤防における堤体であってもよいし道路における盛土であってもよい。 FIG. 1 is a diagram showing a state in which the civil engineering structure 1 is constructed. As shown in FIG. 1, the compaction attachment device 100 and the compaction method are used in the construction of constructing the civil engineering structure 1 from the concrete material or the CSG material. Here, the case where the civil engineering structure 1 is a part of the embankment in the dam will be described, but the civil engineering structure 1 may be the embankment in the embankment or the embankment in the road.

まず、土木構造物１を構築するための材料であるコンクリート材料又はＣＳＧ材料について説明する。 First, a concrete material or a CSG material, which is a material for constructing the civil engineering structure 1, will be described.

コンクリート材料は、寸法別に選定された骨材にセメント及び水を混合して製造されるセメント系材料である。スランプ値が３ｃｍ未満となるように、スランプ値が３ｃｍ以上である有スランプコンクリート材料に比して単位セメント量及び単位水量を少なくした貧配合のコンクリート材料は、超硬練りコンクリート材料とも呼ばれる。超硬練りコンクリート材料の配合は、例えば、最大粗骨材寸法が４０ｍｍを超えて２００ｍｍ以下であり、単位セメント量が９０ｋｇ／ｍ３以上１８０ｋｇ／ｍ３以下であり、水セメント比が５０％以上１２０％以下である。 The concrete material is a cement-based material produced by mixing cement and water with aggregates selected according to dimensions. A poorly mixed concrete material having a unit cement amount and a unit water amount smaller than that of a slump concrete material having a slump value of 3 cm or more so that the slump value is less than 3 cm is also called a cemented carbide concrete material. For example, the maximum coarse aggregate size is more than 40 mm and 200 mm or less, the unit cement amount is 90 kg / m 3 or more and 180 kg / m 3 or less, and the water cement ratio is 50% or more. It is 120% or less.

なお、「スランプ値」は、固化前のセメント系材料の軟らかさを示す値であり、スランプ値が大きいほど軟らかいことを意味する。スランプ値は、例えばＪＩＳ（日本工業規格）Ａ １１０１：２００５に規定されているスランプ試験方法により測定される。 The "slump value" is a value indicating the softness of the cement-based material before solidification, and the larger the slump value is, the softer it is. The slump value is measured by, for example, the slump test method specified in JIS (Japanese Industrial Standards) A 1101: 2005.

ＣＳＧ材料は、建設現場周辺で得られる砂礫や岩塊等の掘削土質材料（現地発生材とも呼ばれる）にセメント及び水を混合して製造されるセメント系材料である。ＣＳＧ材料の配合は、例えば、最大粗骨材寸法が４０ｍｍを超えて９０ｍｍ以下であり、単位セメント量が５０ｋｇ／ｍ３以上１２０ｋｇ／ｍ３以下であり、水セメント比が５０％以上１２０％以下である。ＣＳＧ材料は、セメントの凝固反応を遅延させる凝固遅延剤を含んでいてもよい。 The CSG material is a cement-based material produced by mixing cement and water with excavated soil materials (also called locally generated materials) such as gravel and rock mass obtained around a construction site. The composition of the CSG material is, for example, that the maximum coarse aggregate size is more than 40 mm and 90 mm or less, the unit cement amount is 50 kg / m 3 or more and 120 kg / m 3 or less, and the water cement ratio is 50% or more and 120% or less. Is. The CSG material may contain a coagulation retarder that delays the coagulation reaction of the cement.

超硬練りコンクリート材料及びＣＳＧ材料は、有スランプコンクリート材料に比して単位セメント量が少ないため、原材料費を低減することができる。また、超硬練りコンクリート材料及びＣＳＧ材料は、有スランプコンクリート材料に比して単位水量が少なく未固化状態において流動性が低いため、型枠を設けずに所望の形状に打設することができ、土木構造物１の構築期間を短縮することができる。さらに、超硬練りコンクリート材料及びＣＳＧ材料は、有スランプコンクリート材料に比して単位セメント量及び単位水量が少ないため、水和熱による温度上昇を抑えることができ、水和熱に起因するひび割れを軽減することができる。 Since the cemented carbide material and the CSG material have a smaller unit cement amount than the slump concrete material with slump, the raw material cost can be reduced. Further, since the cemented carbide concrete material and the CSG material have a smaller unit water amount and lower fluidity in the unsolidified state than the slump concrete material with slump, they can be cast into a desired shape without providing a formwork. , The construction period of the civil engineering structure 1 can be shortened. Furthermore, since the ultra-hardened concrete material and the CSG material have a smaller unit cement amount and unit water amount than the slump concrete material, the temperature rise due to the heat of hydration can be suppressed, and cracks caused by the heat of hydration can be prevented. Can be mitigated.

次に、図１を参照して、土木構造物１を構築する手順の概略を説明する。 Next, with reference to FIG. 1, the outline of the procedure for constructing the civil engineering structure 1 will be described.

まず、地盤上に超硬練りコンクリート材料又はＣＳＧ材料を盛立てて断面台形状の土木構造物１を形成する。具体的には、不図示のダンプトラック等を用いて搬送された超硬練りコンクリート材料又はＣＳＧ材料を荷卸しして、不図示のブルドーザ等を用いて敷き均し、転圧ローラ、振動ローラ等の大型重機により締固める。超硬練りコンクリート材料又はＣＳＧ材料の荷卸し、敷き均し及び締固めを複数回繰り返して複数の層を形成することにより、断面台形状の土木構造物１が形成される。 First, a cemented carbide kneaded concrete material or a CSG material is piled up on the ground to form a civil engineering structure 1 having a trapezoidal cross section. Specifically, the cemented carbide concrete material or CSG material transported using a dump truck (not shown) is unloaded, spread evenly using a bulldozer (not shown), a rolling roller, a vibrating roller, etc. Compact with a large heavy machine. By repeating unloading, laying and compaction of the cemented carbide concrete material or CSG material a plurality of times to form a plurality of layers, a civil engineering structure 1 having a trapezoidal cross section is formed.

超硬練りコンクリート材料又はＣＳＧ材料の締固めでは、未固化の超硬練りコンクリート材料又はＣＳＧ材料の表面（法面１ａ及び天面１ｂ）から振動を加えて超硬練りコンクリート材料又はＣＳＧ材料から空気を除去して密度を向上させ、併せて未固化の超硬練りコンクリート材料又はＣＳＧ材料の表面を平滑に仕上げる必要がある。締固めを行うことにより構造体としての強度が確保できる。 In the compaction of a cemented carbide concrete material or CSG material, air is applied from the surface (slope 1a and top surface 1b) of the uncured carbide concrete material or CSG material to air from the cemented carbide concrete material or CSG material. It is necessary to remove the above to improve the density, and at the same time, to finish the surface of the unsolidified cemented carbide material or CSG material to be smooth. By compacting, the strength of the structure can be secured.

以上により、土木構造物１の構築が完了する。 With the above, the construction of the civil engineering structure 1 is completed.

締固めアタッチメント装置１００及び締固め方法は、土木構造物１の締固め作業において用いられる。図１では、締固めアタッチメント装置１００を用いて土木構造物１の法面１ａを締固めている状態を示している。 The compaction attachment device 100 and the compaction method are used in the compaction work of the civil engineering structure 1. FIG. 1 shows a state in which the slope 1a of the civil engineering structure 1 is compacted by using the compaction attachment device 100.

締固めアタッチメント装置１００は、建設機械２におけるアーム２ａの先端に揺動自在に装着されて用いられる。建設機械２は、例えばバックホウであり、自走可能である。建設機械２及びアーム２ａを移動させて締固めアタッチメント装置１００を順次移動させることにより、土木構造物１の全体を締固めることが可能である。 The compaction attachment device 100 is used by being swingably mounted on the tip of the arm 2a in the construction machine 2. The construction machine 2 is, for example, a backhoe and is self-propelled. By moving the construction machine 2 and the arm 2a to sequentially move the compaction attachment device 100, it is possible to compact the entire civil engineering structure 1.

なお、土木構造物１の締固めには、自走可能な不図示の転圧ローラ又は振動ローラを用いることができるが、転圧ローラ又は振動ローラを法面１ａで移動させるのは困難である。締固めアタッチメント装置１００は、建設機械２の駆動により法面１ａで容易に移動可能であるため、法面１ａの締固めにより好適である。同様に、締固めアタッチメント装置１００は、土木構造物１の狭所での締固め作業にも好適である。 A self-propelled rolling roller or vibrating roller (not shown) can be used for compacting the civil engineering structure 1, but it is difficult to move the rolling roller or vibrating roller on the slope 1a. .. Since the compaction attachment device 100 can be easily moved on the slope 1a by driving the construction machine 2, it is more suitable for compaction of the slope 1a. Similarly, the compaction attachment device 100 is also suitable for compaction work in a narrow space of the civil engineering structure 1.

締固めアタッチメント装置１００は、アーム２ａに取付け可能に形成された基体１０と、基体１０に支持された起振機（振動発生部）２０と、起振機２０に連結された締固め部３０と、を備えている。締固め部３０は、土木構造物１に押当てられる板部材３１を備えている。板部材３１を土木構造物１に押当てた状態で起振機２０を作動させて締固め部３０を振動させると、土木構造物１が締固められる。 The compaction attachment device 100 includes a substrate 10 that can be attached to the arm 2a, a vibration exciter (vibration generation unit) 20 supported by the substrate 10, and a compaction unit 30 connected to the exciter 20. , Is equipped. The compaction portion 30 includes a plate member 31 that is pressed against the civil engineering structure 1. When the vibrator 20 is operated in a state where the plate member 31 is pressed against the civil engineering structure 1 to vibrate the compaction portion 30, the civil engineering structure 1 is compacted.

板部材３１を用いた締固めにおいて、板部材３１と土木構造物１の表面との間に空気が封じ込められ介在していると、板部材３１の振動が土木構造物１に十分に伝わらなくなる。また、振動する板部材３１と土木構造物１との間に介在する空気が振動により圧縮され解放されることで、超硬練りコンクリート材料又はＣＳＧ材料に混合された骨材が土木構造物１から分離・剥離して表面の平滑性が損なわれる等、締固めが不十分、不良となる。その結果、締固めの作業効率が悪くなるおそれがある。 In compaction using the plate member 31, if air is contained and intervened between the plate member 31 and the surface of the civil engineering structure 1, the vibration of the plate member 31 is not sufficiently transmitted to the civil engineering structure 1. Further, the air interposed between the vibrating plate member 31 and the civil engineering structure 1 is compressed and released by the vibration, so that the aggregate mixed with the super hard kneaded concrete material or the CSG material is released from the civil engineering structure 1. Insufficient compaction and defects such as separation and peeling impairing the smoothness of the surface. As a result, the compaction work efficiency may deteriorate.

そこで、締固めアタッチメント装置１００の締固め部３０には、図２に示すように、板部材３１を貫通する貫通孔３１ｃが複数形成されている。そのため、板部材３１と土木構造物１の表面との間に介在する空気は、板部材３１を振動させる締固め作業時に貫通孔３１ｃを通じて抜ける。したがって、板部材３１と土木構造物１の表面との間に空気が封じ込められ介在することを防止することができ、板部材３１の振動を土木構造物１に十分に伝えることができる。これにより、土木構造物１を効率よく締固めることができる。 Therefore, as shown in FIG. 2, a plurality of through holes 31c that penetrate the plate member 31 are formed in the compaction portion 30 of the compaction attachment device 100. Therefore, the air interposed between the plate member 31 and the surface of the civil engineering structure 1 escapes through the through hole 31c during the compaction work in which the plate member 31 is vibrated. Therefore, it is possible to prevent air from being trapped and intervening between the plate member 31 and the surface of the civil engineering structure 1, and the vibration of the plate member 31 can be sufficiently transmitted to the civil engineering structure 1. As a result, the civil engineering structure 1 can be efficiently compacted.

締固めアタッチメント装置１００の構造を、図２を参照して詳述する。図２（ａ）は、締固めアタッチメント装置１００の断面図であり、図２（ｂ）は、締固めアタッチメント装置１００の底面図（図２（ａ）における矢印ＩＩＢの方向に見た図）である。 The structure of the compaction attachment device 100 will be described in detail with reference to FIG. FIG. 2A is a cross-sectional view of the compaction attachment device 100, and FIG. 2B is a bottom view of the compaction attachment device 100 (viewed in the direction of arrow IIB in FIG. 2A). be.

図２（ａ）に示すように、基体１０は、アーム２ａ（図１参照）の先端に連結されるブラケット１１と、ブラケット１１に取付けられたフレーム１２と、を備えている。フレーム１２は、断面が略コ字状に形成されており、弾性部材１３を介して起振機２０を挟持している。弾性部材１３は、例えば、ゴム板と鋼板とを交互に積層した積層ゴムである。 As shown in FIG. 2A, the substrate 10 includes a bracket 11 connected to the tip of the arm 2a (see FIG. 1) and a frame 12 attached to the bracket 11. The frame 12 has a substantially U-shaped cross section, and holds the oscillator 20 via the elastic member 13. The elastic member 13 is, for example, laminated rubber in which rubber plates and steel plates are alternately laminated.

起振機２０は、図２（ａ）における上下方向に振動可能に形成されている。図２（ａ）では、起振機２０の筐体のみが示されており、起振機２０の内部構造の図示が省略されている。起振機２０の内部構造を簡単に説明すると、起振機２０は、電動モータと、電動モータの駆動により同位相で互いに逆回転する一対の回転軸と、一対の回転軸に偏心してそれぞれ設けられた一対の回転子と、を備えている。一対の回転軸は、図２（ａ）における紙面垂直方向に延びかつ図２（ａ）における左右方向に並列して設けられている。そのため、電動モータの駆動により一対の回転子が回転すると、左右方向の遠心力は打ち消され、上下方向の遠心力だけが残る。その結果、上下方向に起振力が生じ、起振機２０が上下方向に振動する。以下において、起振機２０が振動する方向（図２（ａ）における上下方向）を「振動方向」とも称する。 The oscillator 20 is formed so as to be vibrable in the vertical direction in FIG. 2A. In FIG. 2A, only the housing of the exciter 20 is shown, and the illustration of the internal structure of the exciter 20 is omitted. Briefly explaining the internal structure of the oscillating machine 20, the oscillating machine 20 is provided with an electric motor, a pair of rotating shafts that rotate in opposite phases in the same phase by driving the electric motor, and a pair of rotating shafts that are eccentric to each other. It is equipped with a pair of rotors and a pair of rotors. The pair of rotation axes extend in the direction perpendicular to the paper surface in FIG. 2A and are provided in parallel in the left-right direction in FIG. 2A. Therefore, when the pair of rotors are rotated by the drive of the electric motor, the centrifugal force in the left-right direction is canceled and only the centrifugal force in the up-down direction remains. As a result, a vibrating force is generated in the vertical direction, and the vibrating machine 20 vibrates in the vertical direction. Hereinafter, the direction in which the oscillator 20 vibrates (the vertical direction in FIG. 2A) is also referred to as a “vibration direction”.

起振機２０は振動を伝達するベース部２１を有する。ベース部２１は例えば、少なくとも一部にプレート（板）形状の部分を含み、プレート形状の板面は、板部材３１の板面である背面３１ｂと対向している。起振機２０のベース部２１は、ボルトナット（不図示）を用いて締固め部３０と連結されている。起振機２０の振動はベース部２１を通じて締固め部３０に伝達される。 The vibration exciter 20 has a base portion 21 for transmitting vibration. The base portion 21 includes, for example, at least a part thereof having a plate-shaped portion, and the plate-shaped plate surface faces the back surface 31b, which is the plate surface of the plate member 31. The base portion 21 of the exciter 20 is connected to the compaction portion 30 by using bolts and nuts (not shown). The vibration of the oscillator 20 is transmitted to the compaction portion 30 through the base portion 21.

締固め部３０は、板部材３１と、板部材３１を補強する補強リブ３２と、を備えている。そのため、締固め時に板部材３１が変形するのを補強リブ３２によって防止することができる。したがって、板部材３１を軽量化でき効率よく土木構造物１（図１参照）を締固めることができる。補強リブ３２は、板部材３１の板面である背面３１ｂと交差して延在する部分を有する鋼製の部材であって、板部材３１の変形を防止するものである。 The compaction portion 30 includes a plate member 31 and a reinforcing rib 32 for reinforcing the plate member 31. Therefore, the reinforcing rib 32 can prevent the plate member 31 from being deformed during compaction. Therefore, the plate member 31 can be reduced in weight and the civil engineering structure 1 (see FIG. 1) can be compacted efficiently. The reinforcing rib 32 is a steel member having a portion extending so as to intersect the back surface 31b, which is the plate surface of the plate member 31, and prevents the plate member 31 from being deformed.

板部材３１は、土木構造物１に押当てられる施工面３１ａと、施工面３１ａとは反対側に位置する背面３１ｂと、施工面３１ａと背面３１ｂとの間を貫通する複数の貫通孔３１ｃと、を有している。図２（ａ）及び（ｂ）に示すように、補強リブ３２は、背面３１ｂに格子状に設けられ、連結されている。 The plate member 31 includes a construction surface 31a pressed against the civil engineering structure 1, a back surface 31b located on the opposite side of the construction surface 31a, and a plurality of through holes 31c penetrating between the construction surface 31a and the back surface 31b. ,have. As shown in FIGS. 2A and 2B, the reinforcing ribs 32 are provided on the back surface 31b in a grid pattern and are connected to each other.

貫通孔３１ｃの断面は、略円形に形成されており、貫通孔３１ｃの内径は、施工面３１ａと背面３１ｂとの間に渡って略同じである。貫通孔３１ｃの中心軸は、振動方向に沿って延びている。貫通孔３１ｃの断面は、円形に限られず、例えば四角形であってもよい。貫通孔３１ｃの断面積は、施工面３１ａと背面３１ｂとの間に渡って同じでなくてもよく、例えば施工面３１ａから背面３１ｂに向かうにつれ拡大していてもよい。また、貫通孔３１ｃの中心軸は、振動方向に沿っていなくてもよく、施工面３１ａと背面３１ｂとの間を貫通する範囲で振動方向に対して傾いていてもよい。 The cross section of the through hole 31c is formed in a substantially circular shape, and the inner diameter of the through hole 31c is substantially the same across between the construction surface 31a and the back surface 31b. The central axis of the through hole 31c extends along the vibration direction. The cross section of the through hole 31c is not limited to a circle, and may be, for example, a quadrangle. The cross-sectional area of the through hole 31c does not have to be the same between the construction surface 31a and the back surface 31b, and may be expanded, for example, from the construction surface 31a to the back surface 31b. Further, the central axis of the through hole 31c does not have to be along the vibration direction, and may be inclined with respect to the vibration direction within a range of penetrating between the construction surface 31a and the back surface 31b.

板部材３１の背面３１ｂは、振動方向に起振機２０と対向しており、背面３１ｂの一部は、振動方向に背面３１ｂを見て起振機２０に覆われた被覆領域ＣＡとなっている。貫通孔３１ｃの一部は、被覆領域ＣＡに開口している。 The back surface 31b of the plate member 31 faces the oscillator 20 in the vibration direction, and a part of the back surface 31b becomes a covering region CA covered with the oscillator 20 by looking at the back surface 31b in the vibration direction. There is. A part of the through hole 31c is open to the covering region CA.

起振機２０の振動を板部材３１に伝達するためには、所定の大きさの被覆領域ＣＡが必要となる。仮に、起振機２０が板部材３１の背面３１ｂに密着しており貫通孔３１ｃの一部を閉塞していると、貫通孔３１ｃの一部から板部材３１と土木構造物１の表面との間の空気が抜けなくなる。その結果、板部材３１と土木構造物１の表面との間に空気が封じ込められ、締固めの作業効率が悪くなるおそれがある。特に、被覆領域ＣＡは起振機２０に対向しており、かつ、板部材３１の中心部に位置するため、締固め不良は顕著となる。 In order to transmit the vibration of the oscillator 20 to the plate member 31, a covering region CA having a predetermined size is required. If the exciter 20 is in close contact with the back surface 31b of the plate member 31 and partially closes the through hole 31c, the plate member 31 and the surface of the civil engineering structure 1 are contacted from a part of the through hole 31c. The air in between cannot escape. As a result, air is trapped between the plate member 31 and the surface of the civil engineering structure 1, and the compaction work efficiency may deteriorate. In particular, since the covering region CA faces the oscillator 20 and is located at the center of the plate member 31, compaction failure becomes remarkable.

締固めアタッチメント装置１００では、図２（ａ）及び（ｂ）に示すように、補強リブ３２の突出する部分に起振機２０が接合されており、補強リブ３２は、板部材３１の背面３１ｂと起振機２０とを離間している。より具体的には、補強リブ３２は起振機２０のベース部２１と板部材３１の背面３１ｂとに所定の空間を確保するように離間する。そのため、被覆領域ＣＡに開口する貫通孔３１ｃからも、板部材３１の施工面３１ａと土木構造物１（図１参照）の表面との間の空気が抜ける。したがって、板部材３１の施工面３１ａと土木構造物１の表面との間に空気が封じ込められ、介在していることをより確実に防止することができる。これにより、土木構造物１をより効率的に締固めることができる。 In the compaction attachment device 100, as shown in FIGS. 2A and 2B, a vibration exciter 20 is joined to a protruding portion of the reinforcing rib 32, and the reinforcing rib 32 is the back surface 31b of the plate member 31. And the oscillator 20 are separated from each other. More specifically, the reinforcing rib 32 is separated from the base portion 21 of the exciter 20 and the back surface 31b of the plate member 31 so as to secure a predetermined space. Therefore, air between the construction surface 31a of the plate member 31 and the surface of the civil engineering structure 1 (see FIG. 1) also escapes from the through hole 31c that opens in the covering region CA. Therefore, it is possible to more reliably prevent air from being trapped and intervening between the construction surface 31a of the plate member 31 and the surface of the civil engineering structure 1. As a result, the civil engineering structure 1 can be compacted more efficiently.

ところで、施工面３１ａにおける貫通孔３１ｃの開口面積が小さ過ぎたり、施工面３１ａにおける貫通孔３１ｃの分布密度が小さ過ぎたりする場合には、板部材３１の施工面３１ａと土木構造物１の表面との間の空気が抜けにくくなる。一方、施工面３１ａにおける貫通孔３１ｃの開口面積が大き過ぎたり、施工面３１ａにおける貫通孔３１ｃの分布密度が大き過ぎたりする場合には、空気は抜けやすくなるものの、施工面３１ａと土木構造物１との接触面積が小さくなり、土木構造物１を締固めにくくなる。 By the way, when the opening area of the through hole 31c on the construction surface 31a is too small or the distribution density of the through hole 31c on the construction surface 31a is too small, the construction surface 31a of the plate member 31 and the surface of the civil engineering structure 1 It becomes difficult for the air between and to escape. On the other hand, if the opening area of the through hole 31c on the construction surface 31a is too large or the distribution density of the through hole 31c on the construction surface 31a is too large, air can easily escape, but the construction surface 31a and the civil engineering structure The contact area with 1 becomes small, and it becomes difficult to compact the civil engineering structure 1.

そこで、施工面３１ａにおける貫通孔３１ｃの開口面積及び分布密度を変えて試験を行った。締固め板である板部材３１の大きさに関して、法面１ａの傾斜方向である縦方向の長さは１．４ｍ又は１．７ｍであり、水平方向である横方向の寸法は１．３ｍである。なお、締固め板である板部材３１の好適な大きさは、縦方向が０．９ｍ以上、２．０ｍ以下であり、横方向が０．９ｍ以上、１．６ｍ以下である。試験の良否は、土木構造物１の締固め作業時における超硬練りコンクリート材料又はＣＳＧ材料の分離・剥離の有無、及び、締固め作業後における土木構造物１の表面の平滑度を目視により判断した。 Therefore, the test was conducted by changing the opening area and the distribution density of the through hole 31c on the construction surface 31a. Regarding the size of the plate member 31 which is a compaction plate, the vertical length of the slope 1a in the inclined direction is 1.4 m or 1.7 m, and the horizontal dimension in the horizontal direction is 1.3 m. be. The suitable size of the plate member 31 which is a compaction plate is 0.9 m or more and 2.0 m or less in the vertical direction, and 0.9 m or more and 1.6 m or less in the horizontal direction. The quality of the test is visually determined by the presence or absence of separation / peeling of the cemented carbide concrete material or CSG material during the compaction work of the civil engineering structure 1 and the smoothness of the surface of the civil engineering structure 1 after the compaction work. did.

その結果、施工面３１ａにおける貫通孔３１ｃの各々の開口面積の合計の割合、つまり、板部材３１の面積に対する開口面積の合計の割合（開口率）を、０．５％（ｍ２／ｍ２）以上４．０％（ｍ２／ｍ２）以下とし、施工面３１ａにおける貫通孔３１ｃの分布密度を３０個／ｍ２以上１００個／ｍ２以下とした場合に、土木構造物１を良好に締固めることができた。また、施工面３１ａにおける貫通孔３１ｃの開口率を０．５％（ｍ２／ｍ２）以上３．０％（ｍ２／ｍ２）以下とし、施工面３１ａにおける貫通孔３１ｃの分布密度を３０個／ｍ２以上７５個／ｍ２以下とした場合に、土木構造物１をより良好に締固めることができた。開口率が上記の設定より小さいと、締固め時作業時に、硬練りコンクリート材料又はＣＳＧ材料の分離・剥離が多く観察され、開口率が上記の設定より大きいと締固め不足の部分が発生することが観察された。また、分布密度が上記の設定より小さいと締固め不足の部分が発生することが観察され、分布密度が上記の設定より大きいと硬練りコンクリート材料又はＣＳＧ材料の分離・剥離が多く観察された。 As a result, the ratio of the total opening area of each through hole 31c on the construction surface 31a, that is, the ratio of the total opening area to the area of the plate member 31 (opening ratio) is 0.5% (m 2 / m 2 ). ) Or more and 4.0% (m 2 / m 2 ) or less, and when the distribution density of the through holes 31c on the construction surface 31a is 30 pieces / m 2 or more and 100 pieces / m 2 or less, the civil engineering structure 1 is good. I was able to compact it. Further, the aperture ratio of the through hole 31c on the construction surface 31a is set to 0.5% (m 2 / m 2 ) or more and 3.0% (m 2 / m 2 ) or less, and the distribution density of the through hole 31c on the construction surface 31a is set. When the number was 30 pieces / m 2 or more and 75 pieces / m 2 or less, the civil engineering structure 1 could be compacted better. If the aperture ratio is smaller than the above setting, separation / peeling of the hardened concrete material or CSG material is often observed during compaction work, and if the opening ratio is larger than the above setting, a part of insufficient compaction occurs. Was observed. Further, when the distribution density was smaller than the above setting, it was observed that a portion of insufficient compaction occurred, and when the distribution density was larger than the above setting, separation / peeling of the hardened concrete material or the CSG material was often observed.

以上のことから、施工面３１ａにおける貫通孔３１ｃの開口率は、０．５％（ｍ２／ｍ２）以上４．０％（ｍ２／ｍ２）以下であり、施工面３１ａにおける貫通孔３１ｃの分布密度は３０個／ｍ２以上１００個／ｍ２以下であることが好ましい。また、施工面３１ａにおける貫通孔３１ｃの開口率は、０．５％（ｍ２／ｍ２）以上３．０％（ｍ２／ｍ２）以下であり、施工面３１ａにおける貫通孔３１ｃの分布密度が３０個／ｍ２以上７５個／ｍ２以下であることがより好ましい。 From the above, the opening ratio of the through hole 31c on the construction surface 31a is 0.5% (m 2 / m 2 ) or more and 4.0% (m 2 / m 2 ) or less, and the through hole on the construction surface 31a. The distribution density of 31c is preferably 30 pieces / m 2 or more and 100 pieces / m 2 or less. The aperture ratio of the through hole 31c on the construction surface 31a is 0.5% (m 2 / m 2 ) or more and 3.0% (m 2 / m 2 ) or less, and the distribution of the through hole 31c on the construction surface 31a. It is more preferable that the density is 30 pieces / m 2 or more and 75 pieces / m 2 or less.

なお、貫通孔３１ｃの内径はφ２０ｍｍ程度（１２ｍｍ～３０ｍｍ）が好ましい。更に好ましくは、１２ｍｍ～２４ｍｍである。 The inner diameter of the through hole 31c is preferably about φ20 mm (12 mm to 30 mm). More preferably, it is 12 mm to 24 mm.

また、起振機２０の起振力が小さ過ぎる場合には、土木構造物１に伝達される振動が弱く、土木構造物１を締固めにくくなるおそれがあり、起振機２０の起振力が大き過ぎる場合には、土木構造物１の表面が崩れるおそれがある。 Further, if the vibrating force of the exciter 20 is too small, the vibration transmitted to the civil engineering structure 1 may be weak and it may be difficult to compact the civil engineering structure 1, and the vibrating force of the exciter 20 may be difficult to compact. If is too large, the surface of the civil engineering structure 1 may collapse.

そこで、施工面３１ａの１ｍ２当たりの起振機２０の起振力を変えて試験を行った。その結果、施工面３１ａの１ｍ２当たりの起振機２０の起振力を５０ｋＮ／ｍ２以上１５０ｋＮ／ｍ２以下とした場合に、土木構造物１を良好に締固めることができた。また、施工面３１ａの１ｍ２当たりの起振機２０の起振力を６０ｋＮ／ｍ２以上１２０ｋＮ／ｍ２以下とした場合に、土木構造物１をより良好に締固めることができた。 Therefore, the test was conducted by changing the vibrating force of the exciter 20 per 1 m 2 of the construction surface 31a. As a result, when the vibrating force of the exciter 20 per 1 m 2 of the construction surface 31a was set to 50 kN / m 2 or more and 150 kN / m 2 or less, the civil engineering structure 1 could be satisfactorily compacted. Further, when the vibrating force of the exciter 20 per 1 m 2 of the construction surface 31a was set to 60 kN / m 2 or more and 120 kN / m 2 or less, the civil engineering structure 1 could be compacted more satisfactorily.

以上のことから、施工面３１ａの１ｍ２当たりの起振機２０の起振力は、５０ｋＮ／ｍ２以上１５０ｋＮ／ｍ２以下であることが好ましい。また、施工面３１ａの１ｍ２当たりの起振機２０の起振力は、６０ｋＮ／ｍ２以上１２０ｋＮ／ｍ２以下であることがより好ましい。貫通孔３１ｃの開口の合計である開口率と貫通孔３１ｃの分布密度と起振機２０の起振力を適切な条件に設定することで、効率的に締固めることができる。 From the above, it is preferable that the vibrating force of the exciter 20 per 1 m 2 of the construction surface 31a is 50 kN / m 2 or more and 150 kN / m 2 or less. Further, it is more preferable that the vibrating force of the exciter 20 per 1 m 2 of the construction surface 31a is 60 kN / m 2 or more and 120 kN / m 2 or less. Efficient compaction can be achieved by setting the aperture ratio, which is the total of the openings of the through holes 31c, the distribution density of the through holes 31c, and the vibration force of the exciter 20 under appropriate conditions.

なお、起振機２０の起振力は、起振機２０における回転子の偏心モーメント量に比例し、起振機２０における回転軸の角振動数の自乗に比例して大きくなり、次式で表される。 The oscillating force of the oscillating machine 20 is proportional to the amount of eccentric moment of the rotor in the oscillating machine 20, and increases in proportion to the square of the angular frequency of the rotating shaft in the oscillating machine 20. expressed.

Ｐ＝（Ｋω２）×１０－３
ただし、Ｐ：起振力（ｋＮ）
Ｋ：回転子の偏心モーメント量（ｋｇ・ｍ）
ω：回転軸の角振動数（ｓｅｃ－１） P = (Kω 2 ) × 10 -3
However, P: vibration force (kN)

ω: Angular frequency of the axis of rotation (sec -1 )

図２（ａ）に示すように、板部材３１は、端部近傍において背面３１ｂ側に折られており、施工面３１ａに対して斜めに延びる傾斜面３１ｄが板部材３１に形成されている。そのため、板部材３１を土木構造物１上で傾斜面３１ｄ側に容易にスライドさせることができる。 As shown in FIG. 2A, the plate member 31 is folded toward the back surface 31b in the vicinity of the end portion, and an inclined surface 31d extending diagonally with respect to the construction surface 31a is formed on the plate member 31. Therefore, the plate member 31 can be easily slid on the civil engineering structure 1 toward the inclined surface 31d.

図２（ｂ）に示すように、締固めアタッチメント装置１００では、振動方向に見て、施工面３１ａの中心Ｃ１は、起振機２０の振動中心Ｃ２に対してオフセットして設けられている。施工面３１ａの中心Ｃ１は、振動方向に見て、起振機２０の振動中心Ｃ２と一致していてもよい。 As shown in FIG. 2B, in the compaction attachment device 100, the center C1 of the construction surface 31a is provided so as to be offset from the vibration center C2 of the oscillator 20 when viewed in the vibration direction. The center C1 of the construction surface 31a may coincide with the vibration center C2 of the oscillator 20 when viewed in the vibration direction.

図３は、締固めアタッチメント装置１００を用いて土木構造物１の法面１ａを締固めている状態を示す拡大図である。図３に示すように、締固めアタッチメント装置１００を用いて土木構造物１の法面１ａを締固める場合には、施工面３１ａの中心Ｃ１が振動方向に見て起振機２０の振動中心Ｃ２よりも鉛直下方に位置するように締固めアタッチメント装置１００の向きを定めることが好ましい。この場合には、締固めアタッチメント装置１００の重量により生じる板部材３１の下端周りのモーメントが土木構造物１の法面１ａに作用する。したがって、土木構造物１の法面１ａをより強い力で押固めることができ、土木構造物１の法面１ａをより効率的に締固めることができる。 FIG. 3 is an enlarged view showing a state in which the slope 1a of the civil engineering structure 1 is compacted by using the compaction attachment device 100. As shown in FIG. 3, when the slope 1a of the civil engineering structure 1 is compacted by using the compaction attachment device 100, the center C1 of the construction surface 31a is the vibration center C2 of the oscillator 20 when viewed in the vibration direction. It is preferable to orient the compaction attachment device 100 so that it is located vertically below. In this case, the moment around the lower end of the plate member 31 generated by the weight of the compaction attachment device 100 acts on the slope 1a of the civil engineering structure 1. Therefore, the slope 1a of the civil engineering structure 1 can be compacted with a stronger force, and the slope 1a of the civil engineering structure 1 can be compacted more efficiently.

以上の実施形態によれば、以下に示す作用効果を奏する。 According to the above embodiments, the following actions and effects are exhibited.

締固めアタッチメント装置１００及び締固め方法では、板部材３１を貫通する貫通孔３１ｃが複数形成されている。そのため、板部材３１と土木構造物１の表面との間に介在する空気は、板部材３１を振動させる締固め作業時に貫通孔３１ｃを通じて抜ける。したがって、板部材３１と土木構造物１の表面との間に空気が封じ込められ介在することを防止することができ、板部材３１の振動を土木構造物１に十分に伝えることができる。これにより、土木構造物１を効率よく締固めることができる。 In the compaction attachment device 100 and the compaction method, a plurality of through holes 31c that penetrate the plate member 31 are formed. Therefore, the air interposed between the plate member 31 and the surface of the civil engineering structure 1 escapes through the through hole 31c during the compaction work in which the plate member 31 is vibrated. Therefore, it is possible to prevent air from being trapped and intervening between the plate member 31 and the surface of the civil engineering structure 1, and the vibration of the plate member 31 can be sufficiently transmitted to the civil engineering structure 1. As a result, the civil engineering structure 1 can be efficiently compacted.

また、締固めアタッチメント装置１００及び締固め方法では、補強リブ３２は、板部材３１の背面３１ｂと起振機２０のベース部２１とを離間している。そのため、被覆領域ＣＡに開口する貫通孔３１ｃからも、板部材３１の施工面３１ａと土木構造物１（図１参照）の表面との間の空気が抜ける。したがって、板部材３１の施工面３１ａと土木構造物１の表面との間に空気が封じ込められるのをより確実に防止することができる。これにより、土木構造物１を効率的に締固めることができる。 Further, in the compaction attachment device 100 and the compaction method, the reinforcing rib 32 separates the back surface 31b of the plate member 31 from the base portion 21 of the oscillator 20. Therefore, air between the construction surface 31a of the plate member 31 and the surface of the civil engineering structure 1 (see FIG. 1) also escapes from the through hole 31c that opens in the covering region CA. Therefore, it is possible to more reliably prevent air from being trapped between the construction surface 31a of the plate member 31 and the surface of the civil engineering structure 1. As a result, the civil engineering structure 1 can be efficiently compacted.

また、施工面３１ａにおける貫通孔３１ｃの各々の開口面積の合計の割合、つまり、板部材３１の面積に対する開口面積の合計の割合（開口率）は、０．５％（ｍ２／ｍ２）以上４．０％（ｍ２／ｍ２）以下であり、施工面３１ａにおける貫通孔３１ｃの分布密度は３０個／ｍ２以上１００個／ｍ２以下である。そのため、板部材３１の施工面３１ａと土木構造物１の表面との間の空気を抜きつつ、施工面３１ａと土木構造物１との接触面積を確保することができる。したがって、土木構造物１をより効率的に締固めることができる。 Further, the ratio of the total opening area of each through hole 31c on the construction surface 31a, that is, the ratio of the total opening area to the area of the plate member 31 (opening ratio) is 0.5% (m 2 / m 2 ). It is 4.0% (m 2 / m 2 ) or less, and the distribution density of the through holes 31c on the construction surface 31a is 30 / m 2 or more and 100 / m 2 or less. Therefore, it is possible to secure a contact area between the construction surface 31a and the civil engineering structure 1 while removing air between the construction surface 31a of the plate member 31 and the surface of the civil engineering structure 1. Therefore, the civil engineering structure 1 can be compacted more efficiently.

施工面３１ａの１ｍ２当たりの起振機２０の起振力は、５０ｋＮ／ｍ２以上１５０ｋＮ／ｍ２以下である。そのため、土木構造物１に伝達される振動が弱くなり過ぎるのを防ぎつつ押固めつつ土木構造物１の表面が崩れるのを防ぐことができる。したがって、土木構造物１をより効率的に締固めることができる。 The vibrating force of the exciter 20 per 1 m 2 of the construction surface 31a is 50 kN / m 2 or more and 150 kN / m 2 or less. Therefore, it is possible to prevent the surface of the civil engineering structure 1 from collapsing while being compacted while preventing the vibration transmitted to the civil engineering structure 1 from becoming too weak. Therefore, the civil engineering structure 1 can be compacted more efficiently.

以上、本発明の実施形態について説明したが、上記実施形態は本発明の適用例の一部を示したに過ぎず、本発明の技術的範囲を上記実施形態の具体的構成に限定する趣旨ではない。 Although the embodiments of the present invention have been described above, the above-described embodiments show only a part of the application examples of the present invention, and the technical scope of the present invention is limited to the specific configuration of the above-described embodiments. do not have.

上記実施形態では、起振機２０は、補強リブ３２の突出する部分に接合されているが、補強リブ３２の突出する部分に不図示の天板が接合され、天板に起振機２０が接合されていてもよい。また、起振機２０は、板部材３１の背面３１ｂから離間した状態で補強リブ３２の側面に接合されていてもよい。つまり、起振機２０と板部材３１の背面３１ｂとが補強リブ３２によって離間させていればよい。 In the above embodiment, the oscillating machine 20 is joined to the protruding portion of the reinforcing rib 32, but a top plate (not shown) is joined to the protruding portion of the reinforcing rib 32, and the oscillating machine 20 is attached to the top plate. It may be joined. Further, the vibration exciter 20 may be joined to the side surface of the reinforcing rib 32 in a state of being separated from the back surface 31b of the plate member 31. That is, the vibrator 20 and the back surface 31b of the plate member 31 may be separated from each other by the reinforcing ribs 32.

上記実施形態では、超硬練りコンクリート材料又はＣＳＧ材料で形成された土木構造物１を締固めアタッチメント装置１００を用いて締固める場合について説明したが、締固めアタッチメント装置１００は、有スランプコンクリート材料で形成された土木構造物１の締固めにも適用可能である。超硬練りコンクリート材料又はＣＳＧ材料は、有スランプコンクリート材料と比較して板部材３１の押固めによる飛散が生じにくい。このような理由から、締固めアタッチメント装置１００は、超硬練りコンクリート材料又はＣＳＧ材料で形成された土木構造物１の締固めに好適である。 In the above embodiment, the case where the civil engineering structure 1 made of the super hard kneaded concrete material or the CSG material is compacted by using the compaction attachment device 100 has been described, but the compaction attachment device 100 is made of a slump concrete material. It can also be applied to compaction of the formed civil engineering structure 1. The cemented carbide kneaded concrete material or CSG material is less likely to scatter due to compaction of the plate member 31 as compared with the slump concrete material with slump. For this reason, the compaction attachment device 100 is suitable for compaction of a civil engineering structure 1 made of a cemented carbide kneaded concrete material or a CSG material.
