JP 2003-138515 A

しかしながら、特許文献１に記載のプレート型振動締固め機のプレート表面は平坦で滑らかなので、締固め対象箇所に転圧力を効率良く伝達できずに長時間にわたって締固め作業を行わなければならず、作業効率が悪いという問題点があった。   However, since the plate surface of the plate-type vibration compacting machine described in Patent Document 1 is flat and smooth, the rolling force cannot be efficiently transmitted to the compaction target location, and the compacting operation must be performed for a long time. There was a problem that work efficiency was bad.

そこで、本発明は、上記のような従来の問題に鑑みなされたものであって、締固め対象箇所を効率良く高密度に締固めることが可能なプレート型振動締固め機及びこのプレート型振動締固め機を用いた締固め方法を提供することを目的とするものである。   Accordingly, the present invention has been made in view of the above-described conventional problems, and is a plate type vibration compaction machine capable of efficiently compacting a compaction target portion at high density and the plate type vibration compaction. An object of the present invention is to provide a compacting method using a compacting machine.

前記目的を達成するため、本発明のプレート型振動締固め機は、振動を発生させるための起振装置を搭載し、この起振装置による振動をプレートを介して締固め対象箇所に伝達して締固めを行うプレート型振動締固め機であって、前記プレートの締固め対象箇所側の表面に凹凸部を備え、前記凹凸部は、前記プレートの表面に研磨材を接着剤で固着することにより形成されることを特徴とする（第１の発明）。 In order to achieve the above object, the plate-type vibration compactor of the present invention is equipped with a vibration generator for generating vibration, and transmits the vibration generated by the vibration generator to the object to be compacted through the plate. A plate-type vibration compacting machine that performs compaction, wherein the plate is provided with a concavo-convex portion on the surface on the side to be compacted, and the concavo- convex portion is formed by fixing an abrasive to the surface of the plate with an adhesive It is formed, characterized in Rukoto (first invention).

本発明のプレート型振動締固め機によれば、プレートの締固め対象箇所側の表面に凹凸部を備えるので、締固め対象箇所に撒き出されている砕石等に振動を損失無く伝えることができ、効率良く締固めることができる。したがって、短時間で締固め対象箇所を高密度に締固めることができる。   According to the plate type vibration compaction machine of the present invention, since the surface of the plate on the side to be compacted is provided with an uneven portion, vibration can be transmitted to the crushed stone or the like squeezed out to the portion to be compacted without loss. , Can be compacted efficiently. Therefore, it is possible to compact the target portion to be compacted in a short time.

また、凹凸部は、プレートに研磨材を接着剤で固着するだけなので、短時間で容易に凹凸部をプレートの表面に取り付けることができる。 Further, since the concavo-convex part is simply fixed to the plate with an adhesive, the concavo-convex part can be easily attached to the surface of the plate in a short time.

第２の発明の路面等を締固める方法は、振動を発生させるための起振装置と、表面に凹凸部を有し、前記起振装置による振動を締固め対象箇所に伝達するプレートとを備え、前記凹凸部は、前記プレートの表面に研磨材を接着剤で固着することにより形成されたプレート型振動締固め機を用いて当該締固め対象箇所を締固める締固め方法において、前記プレートの前記凹凸部を有する面で前記締固め対象箇所に撒き出されているベントナイト粒状体を締固めることを特徴とする。 A method for compacting a road surface or the like according to a second aspect of the present invention includes a vibration generating device for generating vibration, and a plate having a concavo-convex portion on the surface and transmitting the vibration generated by the vibration generating device to a target location. The concavo-convex portion is a compaction method for compacting the portion to be compacted using a plate-type vibration compactor formed by fixing an abrasive to the surface of the plate with an adhesive. The bentonite granular material squeezed out to the portion to be compacted by a surface having an uneven portion is compacted.

本発明のプレート型振動締固め方法によれば、プレートの締固め対象箇所側の表面に設けられた凹凸部で締固め対象箇所に撒き出されているベントナイト粒状体を締固めるので、効率良く高密度に締固めることができる。   According to the plate-type vibration compaction method of the present invention, the bentonite granular material squeezed out to the compaction target portion is compacted by the concavo-convex portion provided on the surface of the plate compaction target portion side. Can be compacted to density.

本発明のプレート型振動締固め機及びこのプレート型振動締固め機を用いた締固め方法によれば、短時間で締固め対象箇所を高密度に締固めることが可能となる。   According to the plate-type vibration compacting machine and the compacting method using the plate-type vibration compacting machine of the present invention, it is possible to compact a portion to be compacted in a short time with high density.

以下、本発明の好ましい実施形態について図面を用いて詳細に説明する。
図１は、本発明の実施形態に係るプレート型振動締固め機１の概略側面図であり、図２は、図１のＡ矢視図である。 Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a schematic side view of a plate-type vibration compactor 1 according to an embodiment of the present invention, and FIG. 2 is a view taken in the direction of arrow A in FIG.

図１及び図２に示すように、プレート型振動締固め機１は、エンジン又は電動機等である駆動源２と、この駆動源２の回転によって振動を発生させる起振装置３と、機体本体の下方の締固め対象箇所を締固めるためのプレート４と、プレート４と起振装置３とを結合して起振装置３による振動をプレート４に伝達するための伝達手段５とを備える。   As shown in FIGS. 1 and 2, a plate-type vibration compactor 1 includes a drive source 2 that is an engine or an electric motor, a vibration generator 3 that generates vibration by the rotation of the drive source 2, and a body body. A plate 4 for compacting a lower portion to be compacted, and a transmission means 5 for coupling the plate 4 and the vibration generator 3 to transmit vibrations from the vibration generator 3 to the plate 4 are provided.

起振装置３は、駆動源２の回転によって偏心荷重を高速回転させることにより振動を発生させる。   The vibration generating device 3 generates vibration by rotating the eccentric load at a high speed by the rotation of the drive source 2.

プレート４は、締固め対象箇所側の表面４ａに凹凸部を備えている。この凹凸部は、例えば、接着剤が塗布された表面４ａに炭化珪素や溶融アルミナ等の研磨材４ｂを吹き付けることにより形成される。本実施形態においては、研磨材４ｂの粒度分布は、ＪＩＳ：Ｒ６２５２に規定されている研磨紙の４０番程度になるように形成した。また、接着剤は、フェノール樹脂やエポキシ樹脂等の合成樹脂接着剤を用いた。   The plate 4 has a concavo-convex portion on the surface 4a on the side to be compacted. This uneven | corrugated | grooved part is formed by spraying abrasives 4b, such as a silicon carbide and a fused alumina, on the surface 4a to which the adhesive agent was apply | coated, for example. In the present embodiment, the particle size distribution of the abrasive 4b is formed to be about No. 40 of the abrasive paper defined in JIS: R6252. Moreover, the synthetic resin adhesives, such as a phenol resin and an epoxy resin, were used for the adhesive agent.

伝達手段５は、起振装置３の支持台１４と、この支持台１４とプレート４との間に挟持される台座１５とから構成されている。   The transmission means 5 includes a support base 14 of the vibration generator 3 and a base 15 sandwiched between the support base 14 and the plate 4.

上述したプレート型振動締固め機１のプレート４を締固め対象箇所に撒き出されているベントナイト粒状体９に押しあてた状態で起振装置３を振動させてベントナイト粒状体９を締固める。ベントナイト粒状体９は、ベントナイト鉱石を破砕して粒径を１０ｍｍ以下に揃えたものを用いた。プレート４の表面４ａは、凹凸状なので、ベントナイト粒状体９に接する面積が増大して起振装置３の振動を効率良くベントナイト粒状体９に伝達することができ、ベントナイト粒状体９を短時間で締固めることができる。   The vibration generator 3 is vibrated in a state where the plate 4 of the plate-type vibration compacting machine 1 is pressed against the bentonite granular material 9 squeezed out to a place to be compacted to compact the bentonite granular body 9. As the bentonite granular material 9, a bentonite ore was crushed to have a particle size of 10 mm or less. Since the surface 4a of the plate 4 is uneven, the area in contact with the bentonite granule 9 is increased, and the vibration of the vibration generator 3 can be efficiently transmitted to the bentonite granule 9. Can be compacted.

次に、プレート４の表面４ａに研磨材４ｂを設けた効果について検証した結果を示す。   Next, the result of having verified about the effect which provided the abrasive | polishing material 4b in the surface 4a of the plate 4 is shown.

プレート４の表面４ａに研磨材４ｂを設けた場合を模擬した紙やすり７ａをプレート４に貼り付けた紙やすりプレート７（詳細は後述する）の締固め性能を、プレート４の表面４ａに何も設けない平滑プレート８（詳細は後述する）及びプレート４の表面４ａに材質及び形状の異なる材料を設けたゴム板プレート６（詳細は後述する）の締固め性能と比較した。   The compaction performance of the sandpaper plate 7 (details will be described later) obtained by pasting the sandpaper 7a simulating the case where the abrasive 4b is provided on the surface 4a of the plate 4 on the surface 4a of the plate 4 is nothing. The comparison was made with the compaction performance of the smooth plate 8 (details will be described later) not provided and the rubber plate 6 (details will be described later) provided with a material having a different shape and shape on the surface 4a of the plate 4.

図３〜図５は、締固め性能を比較するための比較試験用に作製した試験用プレートで、それぞれ平滑な表面４ａの平滑プレート８、表面部がゴム板６ｂのゴム板プレート６、表面部が紙やすり７ａの紙やすりプレート７を示す図である。   FIGS. 3 to 5 are test plates prepared for comparison tests for comparing compaction performance. The smooth plate 8 has a smooth surface 4a, the rubber plate 6 has a rubber plate 6b, and the surface portion has a surface portion. FIG. 6 is a view showing a sandpaper plate 7 of the sandpaper 7a.

図３に示すように、平滑プレート８は、プレート４を円盤状にしたものであり、平滑な表面４ａを有する。この平滑プレート８を振動締固め機に連結した。   As shown in FIG. 3, the smooth plate 8 is a plate-like plate 4 and has a smooth surface 4a. The smooth plate 8 was connected to a vibration compactor.

図４に示すように、ゴム板プレート６は、プレート４の表面４ａに木材６ａを貼り付け、さらに、その上にゴム板６ｂを貼り付けたものである。そして、このゴム板プレート６を振動締固め機に連結した。   As shown in FIG. 4, the rubber plate 6 is obtained by attaching a wood 6a to the surface 4a of the plate 4 and further attaching a rubber plate 6b thereon. The rubber plate 6 was connected to a vibration compactor.

図５に示すように、紙やすりプレート７は、プレート４の表面４ａに紙やすり７ａを貼り付けたものである。紙やすり７ａは、粒度分布が研磨材４ｂと同じ４０番のものを用いた。そして、紙やすりプレート７を振動締固め機に連結した。   As shown in FIG. 5, the sandpaper plate 7 is obtained by pasting the sandpaper 7 a on the surface 4 a of the plate 4. As the sandpaper 7a, No. 40 having the same particle size distribution as the abrasive 4b was used. The sandpaper plate 7 was then connected to a vibration compactor.

図６は、ベントナイト粒状体９を内部に入れた試験用土槽１０を示す図である。
図６に示すように、試験用土槽１０内にベントナイト粒状体９を入れる。本実施形態においては、含水比２１％のベントナイト粒状体９を７Ｋｇ入れた。 FIG. 6 is a view showing a test soil tank 10 in which bentonite granules 9 are placed.
As shown in FIG. 6, bentonite granules 9 are placed in the test soil tank 10. In this embodiment, 7 kg of bentonite granules 9 having a water content of 21% were added.

平滑プレート８、ゴム板プレート６及び紙やすりプレート７をそれぞれ用いて試験用土槽１０内のベントナイト粒状体９を締固めるとともに、ベントナイト粒状体９の層の厚さを測定した。具体的には、まず、各プレート６、７、８でそれぞれ締固め作業を１分間行ったら一旦停止し、そのときのベントナイト粒状体９の層の厚さを測定した。そして、再び、締固め作業を１分間行って層の厚さを測定するという一連の作業を繰り返し行い、層の厚さの変化がなくなった時点で締固めを終了した。   The bentonite granules 9 in the test soil tank 10 were compacted using the smooth plate 8, the rubber plate 6 and the sandpaper plate 7, respectively, and the thickness of the bentonite granules 9 was measured. Specifically, first, when the compacting operation was performed for 1 minute on each of the plates 6, 7, 8, the plate was temporarily stopped, and the thickness of the bentonite granular material 9 at that time was measured. Then, a series of operations of measuring the layer thickness by repeating the compaction operation for 1 minute was repeated, and the compaction was finished when the change in the layer thickness disappeared.

次に、平滑プレート８、ゴム板プレート６及び紙やすりプレート７で、試験用土槽１０内のベントナイト粒状体９をそれぞれ締固めた結果について説明する。   Next, the results of compacting the bentonite granules 9 in the test soil tank 10 with the smooth plate 8, the rubber plate 6 and the sandpaper plate 7 will be described.

図７は、平滑プレート８、ゴム板プレート６及び紙やすりプレート７で締固めを行った時間とベントナイト粒状体９の層の厚さとの関係を示す図である。   FIG. 7 is a diagram showing the relationship between the time during which the smooth plate 8, the rubber plate 6 and the sandpaper plate 7 are compacted and the thickness of the bentonite granular material 9.

図７に示すように、紙やすりプレート７を用いた場合は、締固める前の層の厚さは１１．５０ｍｍで、締固めを１分間行うと７．７０ｍｍとなった。また、ゴム板プレート６を用いた場合は、締固める前の層の厚さが１１．００ｍｍで、締固めを１分間行うと８．２５ｍｍとなった。そして、平滑プレート８を用いた場合は、締固める前の層の厚さが１０．５０ｍｍで、締固めを１分間行うと７．９０ｍｍとなった。これらの結果より、紙やすりプレート７を用いた場合は、ゴム板プレート６及び平滑プレート８を用いた場合よりもベントナイト粒状体９を効率良く締固めていることがわかる。   As shown in FIG. 7, when the sandpaper plate 7 was used, the thickness of the layer before compaction was 11.50 mm, which was 7.70 mm when compacted for 1 minute. When the rubber plate 6 was used, the layer thickness before compaction was 11.00 mm, and when compacted for 1 minute, it was 8.25 mm. When the smooth plate 8 was used, the thickness of the layer before compaction was 10.50 mm, and when compacted for 1 minute, it was 7.90 mm. From these results, it can be seen that when the sandpaper plate 7 is used, the bentonite granules 9 are more efficiently compacted than when the rubber plate 6 and the smooth plate 8 are used.

また、ゴム板プレート６及び平滑プレート８を用いた場合の層の厚さは９分後及び１０分後の値がほぼ同じになったので、１０分以降の締固め作業を終了した。そして、紙やすりプレート７を用いた場合の層の厚さは１４分後及び１５分後の値がほぼ同じになったので、１５分以降の締固め作業を終了した。   Further, since the thickness of the layer when the rubber plate 6 and the smooth plate 8 were used became substantially the same after 9 minutes and after 10 minutes, the compaction work after 10 minutes was finished. When the sandpaper plate 7 was used, the values of the layer thickness after 14 minutes and after 15 minutes were almost the same, so the compaction work after 15 minutes was finished.

次に、平滑プレート８、ゴム板プレート６及び紙やすりプレート７で締固めた各時間におけるベントナイト粒状体９の湿潤密度を算出した。各時間におけるベントナイト粒状体９の湿潤密度ρは（１）式となる。
ρ＝ｍ／Ｖ より
＝ｍ／π・ｒ２・ｈ ・・・（１）式
ここで、湿潤密度：ρ、ベントナイト粒状体９の重量：ｍ、ベントナイト粒状体９の体積：Ｖ、試験用土槽１０の半径：ｒ、試験用土槽１０内におけるベントナイト粒状体９の層厚：ｈである。 Next, the wet density of the bentonite granule 9 at each time when it was compacted with the smooth plate 8, the rubber plate 6 and the sandpaper plate 7 was calculated. The wet density ρ of the bentonite granule 9 at each time is expressed by equation (1).
From ρ = m / V
= M / π · r 2 · h (1) where: wet density: ρ, weight of bentonite granule 9: m, volume of bentonite granule 9: V, radius of test soil tank 10: r The layer thickness of the bentonite granules 9 in the test soil tank 10 is h.

図８は、平滑プレート８、ゴム板プレート６及び紙やすりプレート７で締固めた時間と（１）式より算出された湿潤密度との関係を示す図である。   FIG. 8 is a diagram showing the relationship between the time of compaction by the smooth plate 8, the rubber plate 6 and the sandpaper plate 7 and the wet density calculated from the equation (1).

図８に示すように、紙やすりプレート７を用いた場合は、締固める前の湿潤密度が０．８５０ｇ／ｃｍ３で、締固めを１分間行うと１．２８０ｇ／ｃｍ３となった。また、ゴム板プレート６を用いた場合は、締固める前の湿潤密度が０．９００ｇ／ｃｍ３で、締固めを１分間行うと１．１９０ｇ／ｃｍ３となった。そして、平滑プレート８を用いた場合は、締固める前の湿潤密度が０．９５０ｇ／ｃｍ３で、締固めを１分間行うと１．２４０ｇ／ｃｍ３となった。これらの結果より、紙やすりプレート７を用いた場合は、ゴム板プレート６及び平滑プレート８を用いた場合よりもベントナイト粒状体９を高密度に締固めている。 As shown in FIG. 8, when the sandpaper plate 7 was used, the wet density before compaction was 0.850 g / cm 3 , and when compacted for 1 minute, it was 1.280 g / cm 3 . When the rubber plate 6 was used, the wet density before compaction was 0.900 g / cm 3 , and when it was compacted for 1 minute, it was 1.190 g / cm 3 . Then, in the case of using a smooth plate 8, wet density before compaction is at 0.950 g / cm 3, was performed compaction 1 minute and 1.240g / cm 3. From these results, when the sandpaper plate 7 is used, the bentonite granules 9 are compacted with higher density than when the rubber plate 6 and the smooth plate 8 are used.

上述したように、本実施形態のプレート型振動締固め機１によれば、プレート４の表面４ａに研磨材４ｂからなる凹凸部を備えるので、ベントナイト粒状体９を効率良く短時間でベントナイト粒状体９を高密度に締固めることができる。   As described above, according to the plate-type vibration compactor 1 of the present embodiment, since the surface 4a of the plate 4 is provided with the concavo-convex portions made of the abrasive 4b, the bentonite granules 9 can be efficiently formed in a short time. 9 can be compacted with high density.

さらに、研磨材４ｂの取り付けは、プレート４の表面４ａに接着剤を塗布した後に吹き付けるだけなので、短時間で容易に行うことができる。   Furthermore, since the abrasive 4b is simply sprayed after the adhesive is applied to the surface 4a of the plate 4, it can be easily performed in a short time.

なお、本実施形態においては、研磨材４ｂをプレート４の表面４ａに吹き付けて凹凸部を形成する場合について示したが、これに限定されるものではない。参考例として、耐久性及び耐水性を有する研磨布をプレート４の表面４ａに接着剤で固着してもよく、このときの研磨布は、例えば、上述した研磨材４ｂと同程度の粒度分布を示す研磨布の４０番（ＪＩＳ：Ｒ６２５１）のものを用いる。 In the present embodiment shows the case of forming the uneven portion by blowing the surface 4a of the abrasive 4b plate 4, not name limited thereto. As a reference example, an abrasive cloth having durability and water resistance may be fixed to the surface 4a of the plate 4 with an adhesive, and the abrasive cloth at this time has, for example, a particle size distribution similar to that of the abrasive 4b described above. The polishing cloth shown in No. 40 (JIS: R6251) is used.

また、本実施形態においては、研磨材４ｂの粒度分布がＪＩＳ：Ｒ６２５２に規定の研磨紙の４０番程度になるように形成したが、この粒度分布に限定されるものではなく、ベントナイト粒状体９等の締固め対象材の粒径に応じて適宜決定される。   In this embodiment, the abrasive 4b is formed so that the particle size distribution of the abrasive 4b is about No. 40 of the abrasive paper specified in JIS: R6252. However, the present invention is not limited to this particle size distribution. It is determined appropriately according to the particle size of the material to be compacted.
