Description
【０００１】[0001]
本考案は、電柱の基部を埋設する建柱穴等を形成する掘削装置に関するもので あり、詳細には、丘陵山間地等の大型機械の搬入が難しく、また、岩盤等の土質 に問題がある場所での使用に適した可搬式の掘削装置に関するものである。 The present invention relates to an excavating device for forming a building pole hole or the like for burying the base of an electric pole. Specifically, it is difficult to bring in a large machine such as a mountainous area in a hilly area, and there is a problem in soil quality such as bedrock. The present invention relates to a portable drilling rig suitable for use at a location.
【０００２】[0002]
一般に、電柱の新設・建替を実施するに伴い、電柱の基部を埋設する建柱穴を 丘陵山間地域で掘削する場合があるが、この種の地域の多くは岩盤地帯であり、 平地での掘削作業と比較してかなり手間がかかるものであった。 Generally, as new poles are constructed or rebuilt, pole holes to bury the base of poles may be excavated in the hilly and mountainous areas, but most of this type of area is a rocky area and It took a lot of time and labor compared to excavation work.
【０００３】 ところで、従来の掘削装置として、例えば、螺旋状のブレードを用いたオーガ ドリル等の掘削装置が知られているが、この種の掘削装置は上記の様な岩盤地帯 には適していない。これに対して、岩盤掘削用に適した装置として高深度用の大 型のダウンホールドリル等が開発されているが、これは、平地での基礎工等には 適しているものの、道路等が整備されていない丘陵山間地域では、現場に搬入で きない等の制限があった。By the way, as a conventional excavating device, for example, an excavating device such as an auger drill using a spiral blade is known, but this type of excavating device is not suitable for the rocky areas as described above. . On the other hand, large downhole drills for high depth have been developed as devices suitable for rock excavation, but this is suitable for foundation work on flat ground, but for roads, etc. In the hilly and mountainous area, which has not been maintained, there were restrictions such as being unable to carry it to the site.
【０００４】 そこで、これ等の事情から、丘陵山間地域の掘削作業においては、現場への運 搬が容易なツルスコ・バール等の道具や、電動式の削岩ピックを使って、殆ど手 作業で作業が行われているのが実情である。Under these circumstances, therefore, in the excavation work in the hilly and mountainous areas, tools such as the Tsurusco bar, which are easy to carry to the site, and electric rock drilling picks are used, and most of the work is done manually. The reality is that work is being done.
【０００５】[0005]
ところが、上記の方法で掘削作業を行う場合、所定の深さを確保するためには 、地中側から地面側に拡径する掘削孔、所謂、擂り鉢状の掘削孔を形成しなけれ ばならず、必要以上の労力と時間がかかっており、従って、丘陵山間地における 岩盤での建柱穴の掘削作業においては、本体を現場まで人力で運搬でき、且つ、 岩盤地帯での掘削能力のある掘削装置の開発が強く望まれていた。 However, when excavating by the above method, in order to secure a predetermined depth, it is necessary to form a drill hole that expands from the underground side to the ground side, a so-called mortar-shaped drill hole. Therefore, it takes more labor and time than necessary. Therefore, in the excavation work of the building pillar hole in the rock mass in the hilly and mountainous area, the main body can be manually transported to the site and the excavation capacity in the rock mass area is available. The development of a drilling rig was strongly desired.
【０００６】[0006]
本考案は、上記の課題を解決するため、図１乃至図４に示す如く、掘削装置１ を支持板２と、この支持板２へ立設させた支持管２ａと、支持管２ａへ軸回りに 回動可能に嵌合させた支柱３と、支柱３へスライド管４ａ及び該スライド管４ａ に延設された支持アーム４ｂを介して摺動可能に固定されたコアドリル５から構 成し、支持板２へ重量を有する接地板６を着脱自在に取付け、更に、幾つかの改 良点を加えた。 In order to solve the above problems, the present invention provides a support plate 2 for a drilling device 1, a support pipe 2a provided upright on the support plate 2, and an axial rotation around the support pipe 2a as shown in FIGS. The support 3 includes a support 3 rotatably fitted to the support 3 and a core drill 5 slidably fixed to the support 3 via a slide pipe 4a and a support arm 4b extending from the slide pipe 4a. A heavy ground plate 6 is detachably attached to the plate 2, and some improvements are added.
【０００７】 即ち、本考案の掘削装置１の第１の特徴は、支柱３、コアドリル５等を装着さ せた際の装置本体の転倒を防止し、更に、掘削作業時のコアビット５Ｃの反力を 得られる程度の重量のある接地板６を設けたことである。これにより、装置本体 を、アンカーを打設することなく、安定した状態で地面へ固定することができる 。また、この接地板６には装置本体の水平レベルを調整する調整ボルト７を設け 、傾斜地等での使用性も改善した。That is, the first feature of the excavation device 1 of the present invention is to prevent the device body from tipping over when the support column 3, the core drill 5 and the like are mounted, and further, to counteract the reaction force of the core bit 5C during excavation work. That is, the grounding plate 6 having a weight sufficient to obtain As a result, the device body can be fixed to the ground in a stable state without setting an anchor. In addition, the grounding plate 6 is provided with an adjusting bolt 7 for adjusting the horizontal level of the main body of the apparatus to improve the usability on sloping ground.
【０００８】 本考案の掘削装置の第２の特徴は、全体として分解、組立てが可能であり、作 業員数名での運搬ができることである。特に、上記の接地板６は、かなりの重量 を有しており、丘陵山間地での運搬に支障を来す。このため、この接地板６を支 持板２に対して着脱自在とさせるだけでなく、取手６ａを有する分割型の接地板 ６（実施例では８枚の接地板６Ａ．６Ｂ）として構成した。また、支持板２と支 柱３、支柱３とコアドリル５を分解可能とさせると共に、建柱孔の深さを充分に 確保するために支柱３を分割型とした。尚、この支柱３の側面にはコアドリル５ を上下方向に摺動させるための鋸刃状のラックＲを連続的に形成する必要がある 。このため、支柱３を構成する支柱部材３Ａ．３Ｂ．３Ｃの断面を矩形状とする と共に嵌合式に接合させ、夫々の支柱部材３Ａ．３Ｂ．３ＣのラックＲ．Ｒ．Ｒ が連続的に接合させる様に精密に構成した。The second feature of the excavator of the present invention is that it can be disassembled and assembled as a whole, and can be transported by several operators. In particular, the above-mentioned ground plate 6 has a considerable weight, which hinders transportation in hilly and mountainous areas. Therefore, the ground plate 6 is not only detachable from the support plate 2 but also configured as a split-type ground plate 6 (in the embodiment, eight ground plates 6A and 6B) having a handle 6a. In addition, the support plate 2 and the support pillar 3, and the support pillar 3 and the core drill 5 can be disassembled, and the support pillar 3 is a split type in order to secure a sufficient depth of the building pillar hole. In addition, it is necessary to continuously form a saw-toothed rack R for sliding the core drill 5 in the vertical direction on the side surface of the column 3. Therefore, the pillar members 3A. 3B. 3C has a rectangular cross section and is joined in a fitting manner, and each of the column members 3A. 3B. Rack R. of 3C. R. It was precisely constructed so that R 2 was continuously bonded.
【０００９】 これ等の構成により、本考案の掘削装置１は、各構成部品を作業員一人当りの 運搬可能な重量に分けることができるだけでなく、例えば、小型の運搬車両を使 用する際の集積効率を改善させたのである。With such a configuration, the excavator 1 of the present invention can not only divide each component into a weight that can be carried by one worker, but also, for example, when using a small transport vehicle. It improved the efficiency of integration.
【００１０】 本考案の第３の特徴は、この種の土木作業に適した幾つかの改良点を備えてい ることである。先ず、岩盤を掘削する場合、コアービット５Ｃの切削チップ５ｂ を保護するために水を建柱穴に注入するが、この際、水と岩屑とがヘドロ状の泥 になり、コアービット５Ｃを構成するコアーチューブに付着してコアドリル５の 上昇が困難となる場合がある。本考案は、これを回避させるために、コアビット ５Ｃの上面に複数個の排出孔５ａを設け、泥の排出を可能とさせた。A third feature of the present invention is that it has several improvements suitable for this type of civil engineering work. First, when excavating rock, water is injected into the building pillar hole in order to protect the cutting tip 5b of the core bit 5C. At this time, the water and debris become sludge-like mud to form the core bit 5C. It may adhere to the core tube and make it difficult to raise the core drill 5. In order to avoid this, the present invention provides a plurality of discharge holes 5a on the upper surface of the core bit 5C to enable the discharge of mud.
【００１１】 また、このコアビット５Ｃを支持する支柱３は、軸回りに３６０度の回転が可 能であり、更に、位置決め溝３ｂと芯出ボルト８から成る位置決め手段を設けた ため、掘削作業の最中に、一旦、コアビット５Ｃを建柱穴の真上から作業者側に ９０度乃至１８０度程度に反転させ、建柱穴から岩屑等の排出作業等を行った後 に、再び、コアビット５Ｃを建柱穴の真上に位置させることを可能とした。Further, the column 3 supporting the core bit 5C can rotate 360 degrees around the axis, and further, since the positioning means including the positioning groove 3b and the centering bolt 8 is provided, it can be used for excavation work. In the middle, the core bit 5C is once inverted from directly above the building post hole to the worker side by about 90 to 180 degrees, and after discharging work such as debris from the building post hole, the core bit is again opened. It was possible to position 5C directly above the building hole.
【００１２】[0012]
本考案の主な目的は、以上の如く、丘陵山間地への運搬が可能で、且つ、低深 度の岩盤掘削に適した掘削装置を提供し、この種の丘陵山間地での掘削に係る作 業時間を大幅に短縮させることである。 As described above, the main object of the present invention is to provide an excavation device that can be transported to a hilly and mountainous area and is suitable for low-depth rock excavation, and relates to excavation in this type of hilly and mountainous area. It is to significantly reduce the working time.

【作用】 本考案の掘削装置１を使用するには、予め、分解された状態で現場に運搬し、 そこで、各構成部品を組み立てて使用する。In order to use the excavator 1 of the present invention, the excavator 1 is transported to the site in a disassembled state in advance, and each component is assembled and used there.
【００３４】 掘削現場にて所定深度の建柱穴を形成するには、先ず、組み立てた掘削装置１ を所定の位置に接地する。この際、掘削現場が傾斜地であれば、接地板６の調整 ボルト７の長さを調整して水平レベルを調整する。In order to form a building hole with a predetermined depth at the excavation site, first, the assembled excavation device 1 is grounded at a predetermined position. At this time, if the excavation site is a sloping ground, the length of the adjusting bolt 7 of the ground plate 6 is adjusted to adjust the horizontal level.
【００３５】 次に、コアビット５Ｃを所定の位置に接地させ、駆動部５Ａへ電力を供給させ て回転軸５Ｂとコアビット５Ｃを一体に回転させる。この状態で、コアビット５ Ｃの先端の切削チップ５ｂが岩盤上を回転し、これに、回転軸５Ｂと駆動部５Ａ 等の自重による圧縮力が作用するので、岩盤は、次第にコアビット５Ｃの円周と 同形状に掘削される。尚、この際、切削チップ５ｂを保護するために、適宜に注 水を行う。Next, the core bit 5C is grounded at a predetermined position, and electric power is supplied to the drive unit 5A to rotate the rotating shaft 5B and the core bit 5C integrally. In this state, the cutting tip 5b at the tip of the core bit 5C rotates on the bedrock, and the compression force due to the own weight of the rotating shaft 5B and the drive unit 5A acts on this, so that the bedrock gradually moves around the circumference of the core bit 5C. It is excavated in the same shape as. At this time, water is appropriately injected to protect the cutting tip 5b.
【００３６】 岩盤が前記回転軸５Ｂの送り量に応じた深さに切り込まれた後には、一但、コ アビット５Ｃを上方に引出し、支柱３を回動させてコアビット５Ｃを作業者側に 反転させ、ノミ等を使った手作業で、中心部の岩盤を破壊し、バキューム装置等 を使用して適度にこれを除去する。After the bedrock has been cut to a depth corresponding to the feed amount of the rotary shaft 5B, the core bit 5C is pulled out upward and the support column 3 is rotated to move the core bit 5C to the operator side. Invert and manually destroy the rock mass in the center with a chisel, etc., and remove it appropriately using a vacuum device.
【００３７】 次に、再び、支柱３を回動させてコアビット５Ｃを建柱穴の上部に位置させる 。この際、支柱３は、図３に示す芯出ボルト８と位置決め溝３ｂの関係で一定の 回動位置に芯出しされるので、コアビット５Ｃは正確に建柱穴の真上に位置決め される。Next, the pillar 3 is again rotated to position the core bit 5C above the building pillar hole. At this time, since the support column 3 is centered at a fixed rotation position due to the relationship between the centering bolt 8 and the positioning groove 3b shown in FIG. 3, the core bit 5C is accurately positioned right above the building post hole.
【００３８】 そして、前述と同様な手順を数回に亘って繰り返すことにより、コアドリル５ の回転軸５Ｂの送り量に応じた所定の深さの建柱穴が形成される。コアビット５ Ｃが所定の深さまで達したら、回転軸５Ｂ及びコアビット５Ｃを地中から引抜く ことにより掘削作業は終了する。Then, by repeating the same procedure as described above several times, a building pillar hole having a predetermined depth corresponding to the feed amount of the rotary shaft 5B of the core drill 5 is formed. When the core bit 5C reaches a predetermined depth, the rotary shaft 5B and the core bit 5C are pulled out from the ground to complete the excavation work.
【００３９】 尚、注水及び岩盤の破壊時に生じるヘドロ状の泥水は、コアビット５Ｃの上面 の排出孔５ａから適度に排出されるので、掘削作業が円滑に行われることは言う までもない。Needless to say, since the sludge-like muddy water generated when water is poured and the rock is broken is appropriately discharged from the discharge hole 5a on the upper surface of the core bit 5C, the excavation work is smoothly performed.
【００４０】 掘削作業が終了したら、掘削装置１の各構成部品を分解し、現場から搬出する 。When the excavation work is completed, each component of the excavation device 1 is disassembled and taken out from the site.
