Description
本発明は、落石防止柵の支柱を埋入するための孔を削孔する落石防止柵支柱用の削孔方法に関するものである。 The present invention relates to a drilling method for a rockfall prevention fence column that drills a hole for embedding a column of a rockfall prevention fence.
落石が予想される急斜面の下に道路、建物、鉄道等があるときには、落石を受け止める落石防止柵を構築する。この落石防止柵としては、コンクリート製の擁壁を地中深く埋め込んだり、金属製のネットや板（防止壁）を支柱で支えたりするものがある。前者は工事が大掛かりになるとともに、資材も多く必要とする。このため、後者の方法が多く採用されているが、問題となるは、支柱を埋入する孔を掘るための削孔機の運搬、据付け、運転である。 When there are roads, buildings, railways, etc. under steep slopes where rockfalls are expected, rockfall prevention fences will be constructed to catch rockfalls. As this rock fall prevention fence, there are things that embed concrete retaining walls deep underground and support metal nets and plates (prevention walls) with pillars. The former requires a large amount of construction and a lot of materials. For this reason, the latter method is often adopted, but the problem is transportation, installation, and operation of a drilling machine for digging a hole for embedding a column.
落石防止柵は、落石が起こる場所との間隔が短い斜面の中腹に設けるのが落石の衝撃を軽減でき、支柱や防止壁の強度もそれほど要求されずに好ましい。ところが、このような場所に削孔機を運搬したり、据付けたりするためには、平坦地にするために山を切り開いて運搬路や据付け場所を確保する必要がある。しかし、斜面の中腹にこのような工事をするとなると、その施工に経費がかかるとともに、工期も長くなる。下記特許文献１に、地面に簡易なアンカーを立ててこの上に基礎ブロックを構築し、この基礎ブロックに支柱を立てたものが提案されているが、アンカーや基礎ブロックということになれば、ある程度の整地が必要になるし、強度も必要になる。一方、強度の足りないものであれば安定性に欠ける。 The rock fall prevention fence is preferably provided on the middle of the slope with a short distance from the place where the rock fall occurs, because the impact of the fall rock can be reduced, and the strength of the support column and the prevention wall is not required so much. However, in order to transport or install the drilling machine to such a place, it is necessary to cut a mountain to secure a transportation path and an installation place in order to make it flat. However, if such construction is performed on the slope, it will cost money and the construction period will be longer. In Patent Document 1 below, a simple anchor is set up on the ground, a basic block is constructed on this, and a pillar is set up on this basic block. It is necessary to level the ground and strength. On the other hand, if the strength is insufficient, the stability is insufficient.
本発明は、落石防止柵支柱用の削孔に際し、削孔機の運搬、据付け、運転を斜面の中腹に敢えて整地することなく架設（敷設）できる軌条を走行できる運搬車で行うことで、工費の節減や工期の短縮を可能にしたものである。 The present invention, when drilling holes for rock fall prevention fence posts, transports, installs, and operates the drilling machine with a transporting vehicle that can run on a rail that can be laid (laid) without intentionally leveling the slope. This makes it possible to reduce costs and shorten the construction period.
以上の課題の下、本発明は、請求項１に記載した、落石が予想される目的地までの斜面にラックが貼設される軌条を敷設し、この軌条を走行する運搬車に削孔機、資材及び人員を搭載して目的地まで進行し、目的地において、削孔機を作動させて落石防止柵の支柱の孔を削孔する落石防止柵支柱用の削孔方法において、運搬車が削孔機、資材及び人員を搭載する荷台車と、軌条のラックに強制回転させられるピニオンを噛み合わせて荷台車を牽引する牽引車とからなるものであり、目的地又はその手前までは牽引車及び荷台車が地面に埋設した支持杭で架設される単一の軌条で進行し、目的地では軌条の隣に荷台車に宙に浮いた状態で設けられる第二転動輪ユニットを転動させる一本又は二本の軌条より低位置に設けられる第二軌条を架設し、この軌条及び第二軌条上で荷台車に削孔機を搭載したままで削孔機を作動させることを特徴とする落石防止柵支柱用の削孔方法を提供したものである。
Under the above object, the present invention is described in claim 1, the rack slopes to a destination rock fall is expected laid rail to be affixed, drilling machine in the transport vehicle traveling the rail In the drilling method for a rockfall prevention fence column, the material is carried to the destination with materials and personnel, and the drilling machine is operated to drill the hole in the rockfall prevention fence column at the destination. It consists of a cart loaded with drilling machines, materials and personnel, and a towing vehicle that pulls the cart with a pinion that is forced to rotate on the rail rack. And the carriage is advanced by a single rail constructed by a support pile buried in the ground, and at the destination, a second rolling-wheel unit provided in a floating state in the carriage next to the rail is rolled. from this or two of the railway erection a second rail provided in the low position It is obtained by providing a boring method for rock fall prevention fence post, characterized in that operating the drilling machine in the rail and on the second rail while mounting the drilling machine in the carrier vehicle.
また、本発明は以上の削孔方法において、請求項２に記載した、荷台上で削孔機を据え付ける基礎ベースが左右に移動可能である手段、請求項３に記載した、第二軌条が斜面の中腹で等高線にほぼ沿って敷設される手段、請求項４に記載した、第二軌条が水平に据え付けられるレールベースの両端又は一端に直角に設けられるものであり、レールベースのほぼ中央に軌条が垂直に立設される手段を提供する。 Further, the present invention provides the above-described drilling method, wherein the foundation base for installing the drilling machine on the loading platform described in claim 2 is movable to the left and right, and the second rail described in claim 3 is a slope. Means for laying substantially along the contour line in the middle of the rail, wherein the second rail is provided at right angles to both ends or one end of the rail base to be installed horizontally, and the rail is substantially at the center of the rail base. Provides a means to be installed vertically.
請求項１の発明によると、削孔機の据付け場所までは単一の軌条を走行する運搬車によればよいから、樹木等の伐採は運搬車が走行できるだけの狭い範囲で足りる。これにおいて、軌条は支持杭で支えるものであるから、斜面のままでも施工できる。また、目的地近辺においては第二軌条を敷設し、これで削孔機を搭載する荷台車を支持するものであるから、車体が安定し、削孔機を荷台車に搭載したままで作動できる。この結果、削孔の能率が上がり、工費の節減、工期の短縮が可能になる。 According to the first aspect of the present invention, it is sufficient to use a transport vehicle that travels on a single rail up to the installation location of the drilling machine. Therefore, logging of trees and the like is sufficient in a narrow range that the transport vehicle can travel. In this case, since the rail is supported by the supporting pile, it can be constructed even on the slope. In addition, since the second rail is laid near the destination and this supports the cart that carries the drilling machine, the vehicle body is stable and can operate with the drilling machine mounted on the cart. . As a result, the efficiency of drilling is increased, and the construction cost can be reduced and the construction period can be shortened.
請求項２の手段によれば、荷台車における削孔機のバランスをとることができ、単一の軌条での運搬や作動時の重荷重に対応できる。請求項３の手段によれば、落石防止柵は等高線に沿って構築されるから、その支柱の孔も運搬車を少しずつ移動して連続して削孔することができ、工事を効率的にできる。加えて、軌条や第二軌条も斜面に敷設できるのであるから、落石防止柵を落石が始まる斜面の中腹に構築できることになり、過度の強度の落石防止柵は必要ない。請求項４の手段によれば、軌条及び第二軌条が簡単で精度よく敷設できる。 According to the means of claim 2, it is possible to balance the drilling machine in the cart, and it is possible to handle heavy loads during transportation and operation with a single rail. According to the third aspect of the present invention, since the rockfall prevention fence is constructed along the contour line, the hole of the column can also be continuously drilled by moving the carriage little by little. it can. In addition, since the rail and the second rail can also be laid on the slope, a rockfall prevention fence can be constructed on the middle of the slope where rockfall starts, and an excessively strong rockfall prevention fence is not necessary. According to the means of claim 4, the rail and the second rail can be laid easily and accurately.
以下、本発明の実施の形態を図面を参照して説明する。図１は運搬車の側面図、図２は運搬車のうちの荷台車の背面図であるが、この軌条１は所定間隔で地中に埋設された支持杭２で架設（敷設）されているものである。このときの支持杭２は平坦地に埋入されてもよいが、斜面であっても敷設できる。この場合は、斜面を敢えて整地する必要はない。運搬車３は荷を搭載する荷台車４と、荷台車４を牽引する牽引車５とからなる。なお、軌条１は角パイプ等で構成され、下面にはラック６が貼設されている。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a side view of a transport vehicle, and FIG. 2 is a rear view of a cart of the transport vehicle. This rail 1 is constructed (laid) by support piles 2 embedded in the ground at predetermined intervals. Is. The support pile 2 at this time may be embedded in a flat ground, but can be laid even on a slope. In this case, it is not necessary to level the slope. The transport vehicle 3 includes a loading cart 4 that loads a load and a towing vehicle 5 that pulls the loading cart 4. In addition, the rail 1 is comprised with a square pipe etc., and the rack 6 is affixed on the lower surface.
この種の牽引車５や荷台車４は従来周知であるので、ここでは詳説は省略するが、要するに、牽引車は５は動力原（本例では内燃機関エンジン）の動力を減速装置で減速して軌条１を上下から挟む上下二輪ずつの駆動輪と転動輪とからなる駆動輪ユニット７を有しているものである。この場合、駆動輪にはピニオン（図示省略）が形成されており、このピニオンがラック６に噛み合っている。なお、駆動輪ユニット７は従来周知のように水平回動と前後揺動が可能になって軌条１の曲がりと勾配に対応できるようになっている。さらに、本例では、牽引車５の後方に運転者を載せる操縦車８を有しているが、両者が一体になったものもある。 Since this type of towing vehicle 5 and cart 4 are well known in the art, detailed explanation is omitted here. In short, the towing vehicle 5 decelerates the power of the power source (in this example, the internal combustion engine) with a reduction gear. Thus, it has a drive wheel unit 7 composed of two upper and lower drive wheels and a rolling wheel sandwiching the rail 1 from above and below. In this case, a pinion (not shown) is formed on the drive wheel, and the pinion meshes with the rack 6. The drive wheel unit 7 can be horizontally rotated and oscillated back and forth so as to be able to cope with the bending and gradient of the rail 1 as is well known in the art. Furthermore, in this example, although it has the control vehicle 8 which puts a driver on the back of the tow vehicle 5, there exist some which integrated both.
操縦車８の後方には荷台車４が牽引される。本例では二台の荷台車４を牽引しているが、これは何台であってもよい。荷台車４（操縦車８も同様であるが）は、荷台ベース９の下方に同じく軌条１を上下から挟む都合四輪の転動輪からなる転動輪ユニット１０を有し、この転動輪ユニット１０で軌条１を挟んで転動する（水平回動と前後揺動ができるのは上記と同じ）。本例の場合、前方の荷台車４に削孔機１１を搭載し、後方の荷台車４に必要資材１２を搭載している。 The cart 4 is pulled behind the control vehicle 8. In this example, the two carts 4 are pulled, but any number may be used. The loading cart 4 (the same applies to the control vehicle 8) has a rolling wheel unit 10 composed of four rolling wheels for convenience and sandwiching the rail 1 from above and below the loading platform base 9. It rolls across the rail 1 (the same as described above is that it can rotate horizontally and swing back and forth). In the case of this example, the hole drill 11 is mounted on the front cart 4 and the necessary material 12 is mounted on the rear cart 4.
削孔機１１を搭載する荷台車４は荷台ベース９の下に駆動輪ユニット１０とは別の第二転動輪ユニット１３を有している。第二転動輪ユニット１３は軌条１の隣に同じく支持杭２で架設される一本又は二本設けられる後述の第二軌条１４上を転動するものであり、第二軌条１４上を転動する前後二輪の転動輪１５を有するものである（水平回動と前後揺動ができるのは上記と同じ）。なお、転動輪１５は第二軌条１４に対してかなり幅広に形成されており、脱輪を防いでいる。 The loading cart 4 on which the drilling machine 11 is mounted has a second rolling wheel unit 13 that is different from the driving wheel unit 10 under the loading platform base 9. The second rolling wheel unit 13 rolls on the second rail 14, which will be described later, which is provided next to the rail 1 in the same manner as the support pile 2, and is rolled on the second rail 14. It has two front and rear rolling wheels 15 (the same as described above is capable of horizontal rotation and front / rear swing). The rolling wheel 15 is formed so as to be considerably wider than the second rail 14, and prevents the wheel from being removed.
落石防止柵の支柱のような杭を地中に深く埋入するには、杭をハンマーで叩く打撃系、杭を圧入する圧入系、オーガやドリルで孔をあける掘削系と種々のものがあり、いずれによってもよいが、本例では、予め大きめに形成した孔にセメント等で支柱を強固に固定できる掘削系の削孔機１１を例示している。本例の削孔機１１はポール等の支持装置１６と、支持装置１６に吊架されてオーガ等に回転力を付与する駆動装置１７と、駆動装置１７や資材を昇降させるワイヤやハンドルと言った昇降装置１８を有しているものであり、支持装置１６を荷台ベース９に立設しているものである。 In order to embed piles like rockfall prevention fences deep into the ground, there are various types such as a hammering system in which the pile is hit with a hammer, a press-in system in which the pile is press-fitted, and an excavating system in which holes are drilled with an auger or drill. However, in this example, the excavation type drilling machine 11 that can firmly fix the column with cement or the like in a hole formed in advance in large size is illustrated. The drilling machine 11 of this example is called a support device 16 such as a pole, a drive device 17 that is suspended by the support device 16 and applies a rotational force to an auger or the like, and a wire or a handle that raises or lowers the drive device 17 or materials. The lifting / lowering device 18 is provided, and the support device 16 is erected on the cargo bed base 9.
削孔機１１を荷台ベース９に据え付けるには、荷台ベース９の中心に軌条１の幅方向（左右方向）に向けて前後二個の固定スリーブ１９を取り付け、各固定スリーブ１９にそれぞれ取付けバー２０を左右に覗かせてスライド可能に挿入し、各取付けバー２０に基礎ベース２１を載せてこの基礎ベース２１に枠体２２で囲んだ支持装置１６を立設している。したがって、削孔機１１を据え付ける基礎ベース２１は枠体２２と一緒に左右に移動できるようになっている。なお、任意の位置で固定できるボルト等の従来周知の固定構造も設けられている。 In order to install the drilling machine 11 on the loading platform base 9, two front and rear fixing sleeves 19 are attached to the center of the loading platform base 9 in the width direction (left-right direction) of the rail 1, and a mounting bar 20 is attached to each fixing sleeve 19. Is inserted in a slidable manner, and a base base 21 is placed on each mounting bar 20, and a support device 16 surrounded by a frame 22 is erected on the base base 21. Accordingly, the base base 21 on which the drilling machine 11 is installed can be moved left and right together with the frame body 22. A conventionally known fixing structure such as a bolt that can be fixed at an arbitrary position is also provided.
一方、後方の荷台車４には、削孔機１１の運転に必要なエンジン、バッテリー、発電機、制御機構付きの油圧発生装置、空圧発生装置といった種々の附属装置を搭載している。また、この他に、支柱、工具、作業人員を搭載することがある（これらを必要資材１２と称する）。 On the other hand, the rear cart 4 is equipped with various auxiliary devices such as an engine, a battery, a generator, a hydraulic pressure generator with a control mechanism, and an air pressure generator necessary for the operation of the drilling machine 11. In addition to this, a support, a tool, and a worker may be mounted (these are referred to as necessary material 12).
以上の軌条１を落石が予想される個所まで延設する。本発明の場合、この軌条１の路線をできるだけ落石が始まる山の中腹まで延設するのが特徴である。落石の衝撃を軽減して支柱や防止壁の強度が低くても足りるようにして工事費の節減と設備の完璧化を図るためである。この運搬車３は噛合式であって登坂力も強いから、軌条１は斜面を上下するように敷設できるが、少なくとも、工事個所では等高線にほぼ沿う、すなわち、最大傾斜線に直角な方向に敷設する。なお、この理由については後述する。 The above rail 1 is extended to the place where rock fall is expected. In the case of the present invention, the route of the rail 1 is characterized by extending as far as possible to the middle of the mountain where rockfall starts. This is to reduce the impact of falling rocks and reduce the cost of construction and perfect the equipment so that the strength of the pillars and prevention walls is low. Since the transport vehicle 3 is a meshing type and has a strong climbing force, the rail 1 can be laid so as to move up and down the slope, but at least at the construction site, it is laid along a contour line, that is, in a direction perpendicular to the maximum slope line. . This reason will be described later.
目的地の近く又はその手前では（場合によっては全線に亘ってもよい）軌条１の外側に上記した第二軌条１４を軌条１よりも低位置で架設（敷設）する。図３はこの場合の運搬車の荷台の側面図、図４は背面図であるが、本例では、第二軌条１４を軌条１の両側に二本敷設しているが、一本だけの場合もあり、その場合は多くは谷側に敷設される。加えて、本例では、二本の第二軌条１４を渡すレールベース２３を設け、レールベース２３を第二支持柱２４で支えて敷設している。そして、レールベース２３のほぼ中心に軌条１を直角に立設し、これをユニットとして構成している。 The second rail 14 described above is installed (laid) at a position lower than the rail 1 on the outside of the rail 1 near or before the destination (may be over the entire line in some cases). FIG. 3 is a side view of the carrier bed in this case, and FIG. 4 is a rear view. In this example, two second rails 14 are laid on both sides of the rail 1, but only one is used. In this case, many are laid on the valley side. In addition, in this example, a rail base 23 that passes two second rails 14 is provided, and the rail base 23 is supported by a second support column 24 and laid. The rail 1 is erected at a right angle substantially at the center of the rail base 23, and this is configured as a unit.
軌条１の支持杭２は垂直に立設する必要があり、第二軌条１４も一本であろうが二本であろうが、その上面は水平である必要がある。しかも、軌条１と第二軌条１４の高さや幅を設計どおりに合わせなければならない。これを個々に施工するとすれば、施工に手間どることになるが、このようなユニットのレールベース２３を用いることでレベル出しが容易になり、施工が簡単になる利点がある。特に、第二軌条１４を二本敷設するときは大きな意義がある。なお、レールベース２３は第二転動輪ユニット１０の転動輪１５を下から支持するものであるから、地面を平坦地に整地してその上に直接敷設することもある。 The support pile 2 of the rail 1 needs to be erected vertically and the upper surface of the second rail 14 needs to be horizontal, whether it is one or two. Moreover, the height and width of the rail 1 and the second rail 14 must be matched as designed. If this is individually constructed, the construction will be troublesome, but using the rail base 23 of such a unit has the advantage that the leveling becomes easy and the construction is simplified. In particular, when two second rails 14 are laid, this is of great significance. Since the rail base 23 supports the rolling wheels 15 of the second rolling wheel unit 10 from below, the ground base may be leveled on a flat ground and directly laid on the ground.
次に、以上の各設備によって削孔機１１を運搬、据付け、作動させる場合について説明する。落石防止柵を施工する場所（目的地）までは運搬車３は単一の軌条１で進行する。したがって、第二転動輪ユニット１３は宙に浮いた状態で走行することになるが、このとき、削孔機１１を据え付ける基礎ベース２１を左右に動かしてバランスをとる。なお、第二軌条１４は一本のときもあるが、二本敷設するときに備えて第二駆動輪ユニット１３は左右それぞれに常備しておくのが適する。このように、軌条１は単一な支持杭２で地上に架設されるものであるから、周囲の樹木等の伐採は荷台車４或いはその搭載物が通過できる必要最低限でよいし、地面を敢えて整地する必要もない。この点で、コストも安く、施工期間も短い。 Next, the case where the drilling machine 11 is transported, installed, and operated by the above-described facilities will be described. The transport vehicle 3 travels with a single rail 1 up to the place (destination) where the falling rock prevention fence is constructed. Accordingly, the second rolling wheel unit 13 travels in a state of floating in the air. At this time, the base base 21 on which the hole drilling machine 11 is installed is moved left and right to achieve balance. In addition, although the 2nd rail 14 may be one time, it is suitable to always have the 2nd driving wheel unit 13 in the left and right in preparation for laying two. Thus, since the rail 1 is constructed on the ground with the single support pile 2, the cutting of the surrounding trees, etc. may be the minimum necessary for the carriage 4 or its load to pass, There is no need to level the ground. In this respect, the cost is low and the construction period is short.
目的地近辺では、第二軌条１４を設ける。この場合、第二軌条１４の前後単は端側が下がった傾斜にしておき、荷台車４の第二転動輪ユニット１３の転動輪１５が乗り上げ易いようにしておく。なお、転動輪ユニット１０は軌条１を上下から挟んでいるものであるから、軌条１と第二軌条１４との高低差は転動輪ユニット１０と第二転動輪ユニット１３との高低差に合わせておく必要がある。 Near the destination, the second rail 14 is provided. In this case, the front and rear of the second rail 14 are inclined so that the end side is lowered, so that the rolling wheels 15 of the second rolling wheel unit 13 of the cargo cart 4 can easily get on. Since the rolling wheel unit 10 sandwiches the rail 1 from above and below, the height difference between the rail 1 and the second rail 14 matches the height difference between the rolling wheel unit 10 and the second rolling wheel unit 13. It is necessary to keep.
運搬車３が目的地に到着したなら、運搬車３を軌条１及び第二軌条１４にロックし、削孔機１１を搭載したままで作動させる。削孔機１１を作動させたり、支柱等を吊り上げたりするときには当然に支持装置１６にその反力が生ずるから、これを削孔機１１の左右位置を調整しつつ第二軌条１４で受け持つことになる。なお、基礎ベース２１と地面との間にアウトリガ（図示省略) を介在させれば、この機能をより補完することができる。 When the transport vehicle 3 arrives at the destination, the transport vehicle 3 is locked to the rail 1 and the second rail 14 and is operated with the drilling machine 11 mounted. When the drilling machine 11 is operated or the column is lifted, naturally, the reaction force is generated in the support device 16, and this is handled by the second rail 14 while adjusting the left and right positions of the drilling machine 11. Become. In addition, if an outrigger (not shown) is interposed between the base base 21 and the ground, this function can be further complemented.
目的地では、第二軌条１４（軌条１も同じ）を等高線にほぼ沿うように敷設することは上述した。落石防止柵は等高線に沿って構築するのが普通であり、それを支える支柱も複数本が等高線に沿って埋入される。そこで、第二軌条１４を等高線に沿って敷設しておけば、運搬車３を所定距離移動させて削孔機１１を作動させることで、複数本の支柱用の孔を計画どおりに連続して削孔できる。したがって、削孔を効率的にでき、工費の節減、工期の短縮を可能にする。なお、工事に際しては支柱や資材を何回か搬入、搬出する必要もあるが、その都度、この運搬車３で運搬することになる。 As described above, in the destination, the second rail 14 (the same for the rail 1) is laid along the contour line. A rockfall prevention fence is usually constructed along a contour line, and a plurality of supporting pillars are embedded along the contour line. Therefore, if the second rail 14 is laid along the contour line, the hole 3 is moved by a predetermined distance and the hole drilling machine 11 is operated, so that the holes for the plurality of columns are continuously formed as planned. Can drill holes. Therefore, drilling can be performed efficiently, and the construction cost can be reduced and the construction period can be shortened. In the construction, it is necessary to carry in and out the support pillars and materials several times.
