Description
本発明は、例えば、鉄道線路近傍位置等に配線される通信ケーブル群などを収納すべく構築される収納管路、特にトンネル内の鉄道線路近傍位置においてトンネル幅方向端部に構築されるコンクリート製収納管路の構築工法に関するものである。
The present invention relates to a construction method for a storage pipeline constructed to store, for example, a group of communication cables laid near a railway track, and in particular to a construction method for a concrete storage pipeline constructed at the end of a tunnel in the width direction near a railway track inside a tunnel.
トンネル内の鉄道線路近傍位置においても、通信ケーブル群やその他送信ケーブル群を収納するコンクリート製収納管路は構築しなければならない。
ここで、トンネルの内周面はコンクリート仕上げされており、トンネルの幅方向端部側に寄せて収納管路を構築する際、このトンネル側壁が収納管路の側壁として使用することが検討された。
Concrete storage ducts must also be constructed near the railway tracks inside the tunnel to house the communication cables and other transmission cables.
Here, the inner surface of the tunnel is finished in concrete, and when constructing the storage pipeline close to the end of the tunnel in the width direction, it was considered to use this tunnel side wall as the side wall of the storage pipeline.
ところが前記トンネル側壁は、鉄筋から構成された補強筋が埋設されて補強されコンクリート仕上げされており、コンクリート側壁に収納管路の蓋受け載置用にアンカーボルトを打ち込む際、前記補強筋などが障害となる可能性があった。
However, the tunnel side walls are reinforced with embedded reinforcing bars made of steel bars and finished with concrete, and there was a possibility that the reinforcing bars would become an obstacle when driving anchor bolts into the concrete side walls to place the storage pipe cover holders.
本発明は、前記従来の課題を解決するために創案されたものであり、前記アンカーボルトをコンクリート側面に打ち込む際、埋設されている補強筋を避けて打ち込んでも収納管路の蓋受け部材をコンクリート側壁の所定位置に取り付けることが出来、ひいては狭いトンネル内においても収納スペースが広く確保できる収納管路の構築工法を提供することを目的とするものである。
The present invention has been devised to solve the above-mentioned conventional problems, and aims to provide a construction method for storage pipelines that allows the lid receiving member of the storage pipeline to be attached to the specified position on the concrete side wall even when the anchor bolts are driven into the side of the concrete, avoiding the buried reinforcing bars, and ultimately ensures ample storage space even inside a narrow tunnel.

本発明によれば、収納管路の蓋が載置される蓋受け部材をトンネル側壁に固定するアンカーボルトをコンクリート側面に打ち込む際、側壁内に埋設されている補強筋を避けて打ち込んでも収納管路の蓋受け部材をコンクリート側壁の所定位置に取り付けることが出来、ひいては狭いトンネル内においても収納スペースが広く確保できる収納管路の構築工法を提供できるとの優れた効果を奏する。

以下、本発明を図に基づいて説明する。
図１は第１実施例を示し、トンネル１内においてトンネル１の幅方向両端側にケーブル４等を収納するコンクリート製の収納管路２を構築する状態を説明する説明図である。
The present invention will now be described with reference to the accompanying drawings.
FIG. 1 shows a first embodiment, and is an explanatory diagram illustrating the construction of a concrete storage pipe 2 for storing cables 4 and the like on both sides of the tunnel 1 in the width direction.
図１に示す実施例において、該トンネル１内には鉄道用線路３が２車線設けられている。そして、この鉄道車両用の通信ケーブルや電源ケーブルなどのケーブル４は前記トンネル１の幅方向両端側に設けられたコンクリート製の収納管路２に収納されるものとなる。 In the embodiment shown in Figure 1, two lanes of railway track 3 are installed inside the tunnel 1. Cables 4, such as communication cables and power cables for these railway vehicles, are stored in concrete storage pipes 2 installed on both ends of the tunnel 1 in the width direction.
ここで、鉄道用の前記収納管路２については、電磁気などをシールドすべく金属製ではなく、コンクリート製の収納管路２が使用されている。金属製の収納管路を使用すると、電磁波をシールド出来ず、電磁波が収納されている鉄道車両用の通信ケーブルや電源ケーブルなどのケーブル４に悪影響をもたらし、その結果、通信障害などのトラブルを招来する恐れがあるからである。 Here, the storage pipelines 2 for railways are made of concrete rather than metal in order to shield against electromagnetic waves. If metal storage pipelines were used, they would not be able to shield against electromagnetic waves, which could have a negative impact on the cables 4 stored there, such as communication cables and power cables for railway vehicles, and as a result, could lead to problems such as communication failures.
ところで、トンネル１内においてはトンネル幅方向の長さを広げることが出来ない。すなわち、トンネル１には幅方向に両側壁５が存在しており、これにより、トンネル幅方向の長さが決定され、前記両側壁５の間の長さ以上にトンネル幅方向の長さを広げられないのである。 However, the tunnel 1 cannot be expanded in its width direction. That is, the tunnel 1 has two side walls 5 in its width direction, which determine the tunnel's width direction, and the tunnel's width direction cannot be expanded beyond the distance between the two side walls 5.
そのため、特にトンネル１内においてトンネル１の幅方向端部側にケーブル４などの収納用の収納管路２を構築する場合、収納管路２を構成するトンネル側壁側の収納管路側壁を別途立設するのではなく、トンネルの側壁５を一方側の収納管路側壁として使用して構築するのが、トンネル１の幅方向の長さを最大限に取得できるものとなる。しかも、収納管路２を構築するための側壁を別途構築する必要もない。 For this reason, particularly when constructing storage conduits 2 for storing cables 4 and the like at the widthwise end of tunnel 1, the tunnel's side wall 5 can be used as one of the storage conduit side walls, rather than erecting a separate storage conduit side wall on the tunnel side wall that constitutes storage conduit 2, in order to maximize the tunnel's widthwise length. Furthermore, there is no need to construct a separate side wall for constructing storage conduit 2.
このように、トンネルの側壁５を一方側の収納管路側壁として使用すれば、前述の如く収納管路２の収納スペースをトンネル１内において最大限広く使用でき、かつ収納管路２用に新たに側壁を構築する必要もない。 In this way, by using the tunnel side wall 5 as the side wall of one of the storage pipelines, as mentioned above, the storage space for the storage pipelines 2 within the tunnel 1 can be maximized, and there is no need to construct a new side wall for the storage pipelines 2.
ここで、収納管路２の構築工法につき説明する。
まず、トンネル幅方向両端側のトンネル側壁５からトンネル中央部に向かい所定の間隔をあけて収納管路２の収納管路側壁６を立設する。
該収納管路側壁６は、コンクリート製からなる所定の厚みを有する板状の部材で構成し、対向するトンネル側壁５と所定の間隔を有して、前記トンネル側壁５と略平行になるよう略垂直にして立設される。
Here, the construction method of the storage pipeline 2 will be explained.
First, the storage pipeline side walls 6 of the storage pipeline 2 are erected at a predetermined interval from the tunnel side walls 5 on both ends in the tunnel width direction toward the center of the tunnel.
The storage pipeline side wall 6 is made of a plate-like member made of concrete and having a predetermined thickness, and is erected approximately vertically so as to be approximately parallel to the opposing tunnel side wall 5, with a predetermined gap between them.
前記収納管路側壁６の立設後、この収納管路側壁６の上端面高さとほぼ同じ高さ位置において、対向するトンネル側壁５にアンカーボルト７を用いて蓋受け部材９を取り付ける。
上記のようにアンカーボルト７は、収納管路側壁６の上端面と、該上端面と同じ高さのトンネル側壁５との間に収納管路蓋８を載置するべく、該収納管路用蓋８を保持する蓋受け部材９をトンネル側壁５に取り付けるために使用される。
すなわち、アンカーボルト７は蓋受け部材９の取付穴１２を挿通し、前記蓋受け部材９をトンネル側壁５に固定するために使用される。
After erecting the storage pipeline side wall 6, a lid receiving member 9 is attached to the opposing tunnel side wall 5 using anchor bolts 7 at a height position approximately the same as the height of the upper end surface of the storage pipeline side wall 6.
As described above, the anchor bolts 7 are used to attach the lid receiving member 9 that holds the storage pipeline lid 8 to the tunnel side wall 5 in order to place the storage pipeline lid 8 between the upper end surface of the storage pipeline side wall 6 and the tunnel side wall 5 that is at the same height as the upper end surface.
That is, the anchor bolt 7 is inserted through the mounting hole 12 of the cover receiving member 9 and is used to fix the cover receiving member 9 to the tunnel side wall 5.
次に、蓋受け部材９につき説明する。
図２は、蓋受け部材９の正面図であり、図３は側面図である。図２から理解されるように、蓋受け部材９は直線状の略多角棒状をなして構成されており、図３から理解されるように上面が平坦面として構成された蓋載置面１０と該蓋載置部１０の一端部側から略９０度以下の下り勾配角度を有して形成され、表面が平坦面として構成されたトンネル側壁取付面１１を有して構成されている。
Next, the lid receiving member 9 will be described.
Fig. 2 is a front view of the lid receiving member 9, and Fig. 3 is a side view. As can be seen from Fig. 2, the lid receiving member 9 is configured in the shape of a linear, approximately polygonal rod, and as can be seen from Fig. 3, it is configured with a lid mounting surface 10 having a flat upper surface, and a tunnel side wall mounting surface 11 formed at a downward slope angle of approximately 90 degrees or less from one end side of the lid mounting portion 10 and having a flat surface on the surface.
ここで、トンネル側壁取付面１１が蓋載置部１０の一端部側から９０度以下の下り勾配角度を有して形成してあるのは、トンネル側壁５の傾斜角度に合わせたものであり、前記の蓋載置面１０が略水平方向に位置できるように設計したものである。また、図３は蓋受け部材９の側面を示したものであるが、図３に示す様に、その側面の端面は四角形状に形成されず、多角形状に形成されている。すなわち、蓋載置面１０とトンネル側壁取付面１１に対向する残りの２辺については、それら辺の略中間位置から切り取られて略五角形状になるよう構成されている。 The tunnel sidewall mounting surface 11 is formed with a downward slope angle of less than 90 degrees from one end of the lid mounting portion 10 to match the inclination angle of the tunnel sidewall 5 and is designed to allow the lid mounting surface 10 to be positioned approximately horizontally. Also, Figure 3 shows the side of the lid receiving member 9, and as shown in Figure 3, the end faces of this side are not formed in a square shape but in a polygonal shape. In other words, the remaining two sides facing the lid mounting surface 10 and the tunnel sidewall mounting surface 11 are cut off from approximately their midpoints to form an approximately pentagonal shape.
これは、該蓋受け部材９をトンネル側壁５に取り付ける際、トンネル側壁５側に向けるトンネル側壁取付面１１の方向を素早く察知できるようにしたためである。すなわち、この蓋受け部材９の側面形状が略四角形状ではなく、蓋載置面１０とトンネル側壁取付面１１に対向する残りの２辺について、それら２辺の略中間位置から切り取られて略五角形状にしてあれば、容易にトンネル側壁５側に向けるトンネル側壁取付面１１の方向を確認できるからである。 This is because, when attaching the lid receiving member 9 to the tunnel side wall 5, it is possible to quickly determine the direction of the tunnel side wall mounting surface 11 that faces the tunnel side wall 5. In other words, if the side shape of the lid receiving member 9 is not approximately rectangular, but rather the remaining two sides facing the lid placement surface 10 and the tunnel side wall mounting surface 11 are cut out at approximately the midpoint between those two sides to form an approximately pentagonal shape, it is easy to confirm the direction of the tunnel side wall mounting surface 11 that faces the tunnel side wall 5.
また、この蓋受け部材９もコンクリート製品で形成されており、蓋載置面１０とトンネル側壁取付面１１によって構成された隅角に対向する隅角を略三角形状に切り欠いて構成すれば、切り欠いた分だけ材料費を安価にすることが出来るものとなる。 The lid receiving member 9 is also made of concrete, and if the corner opposite the corner formed by the lid mounting surface 10 and the tunnel side wall mounting surface 11 is cut out in a roughly triangular shape, material costs can be reduced by the amount of the cutout.
次に、図２に示す様に、前記隅角を切り欠いた面には、アンカーボルト７が挿通する取付穴１２が設けられている。ここで、該取付穴１２は、図２に示す様に、略水平方向に向かって延出し、緩やかな山状に湾曲した形状の長穴として構成されている。これについては前述したとおりであるが、トンネル側壁５は、地山にコンクリートが打設されてトンネル側壁５が形成されるが、トンネル側壁５の補強のため内部には補強筋が埋設されている。また、地山には大小様々な形状をした岩石なども存在している。 Next, as shown in Figure 2, a mounting hole 12 is provided on the cut-out surface of the corner, through which the anchor bolt 7 is inserted. Here, as shown in Figure 2, the mounting hole 12 is configured as an elongated hole that extends approximately horizontally and has a gently curved mountain-like shape. As mentioned above, the tunnel side walls 5 are formed by pouring concrete into the natural ground, and reinforcing bars are buried inside to reinforce the tunnel side walls 5. The natural ground also contains rocks of various shapes and sizes.
従って場合によっては、アンカーボルト７を打ち込む箇所に補強筋が埋設配置されている場合がある。また、岩石が存在している場合もある。その場合には、長穴を緩やかな山状に湾曲した形状にしておけば、水平方向にアンカーボルト７の打ち込み位置を移動させることも出来、上下方向にもアンカーボルト７の打ち込み位置を移動させることが出来る。すなわち、埋設されている補強筋や岩石をよけてアンカーボルト７を打ち込むことが出来る。取付穴１２を略水平方向に向かって延出させ、かつ緩やかな山状に湾曲した形状の長穴にした所以である。 Therefore, in some cases, reinforcing bars may be buried where the anchor bolt 7 is to be driven. There may also be rocks present. In such cases, if the elongated hole is designed to be gently curved like a mountain, the driving position of the anchor bolt 7 can be moved horizontally and also vertically. In other words, the anchor bolt 7 can be driven in while avoiding buried reinforcing bars and rocks. This is why the mounting hole 12 is designed to extend substantially horizontally and has a gently curved mountain-like shape.
尚、取付穴１２の略水平方向の長さは、少なくとも、補強筋の径とアンカーボルト７の径を加えた長さ以上にする必要がある。このような長さにすれば、補強筋をよけてアンカーボルト７を打ち込むことが出来る。 The approximately horizontal length of the mounting hole 12 must be at least equal to the sum of the diameter of the reinforcing bar and the diameter of the anchor bolt 7. This length allows the anchor bolt 7 to be driven in while avoiding the reinforcing bar.
ところで、補強筋は例えば縦、横に格子状に配筋されるが、横方向に配筋された補強筋と接触する恐れもある。その場合は、取付穴１２が緩やかな山状に湾曲した形状の長穴であるため、前述したように上下方向にも若干調節できるが、若干の調節では対応できない場合は、前記収納管路側壁６の高さ自体を予め調整しておき、横方向の補強筋や岩石と接触しない箇所を選択しておく必要がある。 The reinforcing bars are arranged vertically and horizontally in a grid pattern, for example, but there is a risk that they may come into contact with the reinforcing bars arranged horizontally. In such cases, since the mounting holes 12 are elongated holes with a gently curved mountain shape, they can be slightly adjusted vertically as mentioned above. However, if slight adjustments are not sufficient, it is necessary to adjust the height of the storage pipe side wall 6 itself in advance and select a location that will not come into contact with the horizontal reinforcing bars or rocks.
以上、トンネル１内において、トンネル進行方向長さのすべてに収納管路側壁６を立設し、対向するトンネル側壁５の所定位置にアンカーボルト７を打ち込み、該アンカーボルト７と、該アンカーボルト７が貫挿する緩やかな山状に湾曲した形状の長穴である取付穴１２との調節を図って蓋受け部材９を所定位置のトンネル側壁５に取り付ける。 As described above, within the tunnel 1, the storage pipe side walls 6 are erected along the entire length of the tunnel in the direction of travel, and anchor bolts 7 are driven into the opposing tunnel side walls 5 at predetermined positions. The anchor bolts 7 are then adjusted to fit into the mounting holes 12, which are elongated holes with a gently curved mountain shape through which the anchor bolts 7 pass, and the lid receiving members 9 are attached to the tunnel side walls 5 at the predetermined positions.
そして、完成したトンネル１内の収納管路２内に通信ケーブルや電源ケーブルなどのケーブル４を収納し、前述のように取り付けた蓋受け部材９に収納管路蓋８を載せる。これにより、トンネル１内の収納管路２構築は終了する。 Then, cables 4, such as communication cables and power cables, are stored inside the storage pipeline 2 inside the completed tunnel 1, and the storage pipeline cover 8 is placed on the cover receiving member 9 installed as described above. This completes the construction of the storage pipeline 2 inside the tunnel 1.
次に、図４を参照して第２実施例につき説明する。
第１実施例ではトンネル１内において、地上に立設され、構築された収納管路の構築工法を説明したが、第２実施例では地面より下側に収納管路を構築した例を示したものである。
Next, a second embodiment will be described with reference to FIG.
In the first embodiment, a construction method for a storage pipeline that is erected and constructed on the ground within the tunnel 1 is described, but in the second embodiment, an example is shown in which a storage pipeline is constructed below the ground level.
この実施例によれば、トンネル１の幅方向両側に埋設された収納管路２を構築することが出来、もって収納管路２の上方箇所に空きスペースを設けることが出来る。よって、この上方に設けた空きスペースを何らかの目的のため有効に活用することが出来る。 In this embodiment, buried storage pipelines 2 can be constructed on both sides of the tunnel 1 in the width direction, thereby creating free space above the storage pipelines 2. This free space above can therefore be effectively utilized for some purpose.
尚、第２実施例の適用に関しては、トンネル１の高さが比較的低く形成されたトンネル１に適しているといえる。
該第２実施例の構築工法の概略を説明すると、トンネル側壁５からトンネル１の中央部に向かい、間隔をあけて収納管路用側壁６を地中に埋設する。
It should be noted that the second embodiment is suitable for application to a tunnel 1 that is formed with a relatively low height.
The construction method of the second embodiment will be briefly explained. From the tunnel side wall 5 toward the center of the tunnel 1, storage pipe side walls 6 are buried in the ground at intervals.
そして、埋設した収納管路用側壁６とトンネル幅方向端部のトンネル側壁５との間を掘削して地中収納スペースを形成する。 Then, an underground storage space is created by excavating between the buried storage pipeline side wall 6 and the tunnel side wall 5 at the end of the tunnel width.
次いで、前記収納管路用側壁６の上端面と略同等の高さ位置にある前記トンネル側壁５にアンカーボルト７が挿通する穴が水平方向に延出する長穴として形成された取付穴１２を有し、上面には収納管路用蓋８が載置する載置面１０が設けられた蓋受け部材９を前記取付穴１２にアンカーボルト７を挿通させてトンネル側壁５に取り付ける。 Next, the tunnel side wall 5, which is located at approximately the same height as the upper end surface of the storage pipeline side wall 6, is fitted with a lid receiving member 9 having a mounting hole 12 formed as a horizontally extending elongated hole through which an anchor bolt 7 is inserted, and on whose upper surface is provided a mounting surface 10 on which a storage pipeline lid 8 is placed. The lid receiving member 9 is then attached to the tunnel side wall 5 by inserting the anchor bolt 7 into the mounting hole 12.
その後、収納管路用側壁５の上端面と前記蓋受け部材９の載置面１０に跨がって収納管路用蓋８を載置して第２実施例の収納管路２の構築は完了する。 Then, the storage pipeline lid 8 is placed across the upper end surface of the storage pipeline sidewall 5 and the mounting surface 10 of the lid receiving member 9, completing the construction of the storage pipeline 2 of the second embodiment.
ここで、前記アンカーボルト７による蓋受け部材９のトンネル側壁５への取り付けは、前記トンネル側壁５内に配筋された補強筋あるいは障害物をよけて取り付け可能とすべくアンカーボルト７の貫挿位置を前記取付穴１２内で変更できる構成としてあり、これにより、トンネル側壁５内に埋設された補強筋や岩石などの障害物に邪魔されることなく所定位置に蓋受け部材９を取り付けることが出来、迅速な作業で確実な収納管路２が構築できるものとなる。 Here, the anchor bolts 7 are used to attach the cover receiving member 9 to the tunnel side wall 5. The insertion position of the anchor bolts 7 can be changed within the mounting holes 12 so that the attachment can be made around reinforcing bars or obstacles arranged within the tunnel side wall 5. This allows the cover receiving member 9 to be attached in the specified position without being obstructed by reinforcing bars buried within the tunnel side wall 5 or obstacles such as rocks, enabling the storage pipeline 2 to be constructed quickly and reliably.
以上、トンネル１内における収納管路２の構築工法につき説明したが、本発明の蓋受け部材６は、トンネル１内のほか、トンネルのない通常の鉄道路に構築する収納管路の構築においても使用できるものであり、トンネル外での箇所での収納管路２の構築に大きな効果を発揮するものとなっている。
The construction method for constructing the storage pipeline 2 inside the tunnel 1 has been explained above, but the cover receiving member 6 of the present invention can be used not only inside the tunnel 1 but also in the construction of storage pipelines constructed on ordinary railway roads without tunnels, and is highly effective in constructing storage pipelines 2 at locations outside tunnels.

storage pipeline side walls are erected at intervals from the tunnel side walls toward the tunnel center, a storage space is formed between the erected storage pipeline side walls and the tunnel side walls at the tunnel width direction ends, and a lid receiving member is attached to the tunnel side walls at a height position substantially equal to the upper end faces of the storage pipeline side walls, so that a storage pipeline lid can be placed across the upper end faces of the storage pipeline side walls and the placement surface of the lid receiving member,
The lid receiving member has a linear, approximately polygonal rod shape and includes a flat lid placing surface on the upper surface and a flat tunnel side wall mounting surface formed from one end of the lid placing surface at a downward slope angle of approximately 90 degrees or less in accordance with the inclination angle of the tunnel side wall. The side shape of the lid receiving member is configured to be approximately pentagonal by cutting the remaining two sides facing the lid placing surface and the tunnel side wall mounting surface at approximately the midpoint of the two sides so that the direction of the tunnel side wall mounting surface facing the tunnel side wall can be quickly detected. The tunnel side wall mounting surface is provided with an elongated hole that extends approximately horizontally and is curved gently like a mountain so that an anchor bolt to be driven into the tunnel side wall can be inserted therethrough, allowing the insertion position of the anchor bolt to be moved horizontally and up and down, and the insertion position of the anchor bolt can be changed within the elongated hole to avoid reinforcing bars arranged in the tunnel side wall or buried obstacles.
A construction method for storage pipelines characterized by the above.
トンネル側壁からトンネル中央部に向かい、間隔をあけて収納管路用側壁を埋設し、埋設した収納管路用側壁とトンネル幅方向端部のトンネル側壁との間に収納スペースを形成し、前記収納管路用側壁の上端面と略同等の高さ位置の前記トンネル側壁に蓋受け部材を取り付け、前記収納管路用側壁の上端面と前記蓋受け部材の載置面に跨がって収納管路用蓋を載置可能とし、
前記蓋受け部材は、直線状の略多角棒状をなし、上面が平坦面の蓋載置面と該蓋載置面の一端部側からトンネル側壁の傾斜角度に合わせて略９０度以下の下り勾配角度を有して形成された平坦面のトンネル側壁取付面を有し、該蓋受け部材の側面形状を、トンネル側壁側に向けるトンネル側壁取付面の方向が素早く察知出来るよう前記蓋載置面とトンネル側壁取付面に対向する残りの２辺につき、該２辺の略中間位置から切り取って略五角形状に構成し、前記トンネル側壁取付面には、トンネル側壁に打ち込まれるアンカーボルトが挿通すべく略水平方向に向かって延出し、緩やかな山状に湾曲した形状の長穴が設けられてアンカーボルトの打ち込み位置が水平方向及び上下方向に移動可能とされ、前記トンネル側壁内に配筋された補強筋あるいは埋設障害物をよけるべくアンカーボルトの挿通位置を長穴内で変更できる構成とした、
