Description
この発明は、地中埋設管路の推進工法において、推進中の管路の位置計測を先端位置の計測のみならず、リアルタイムで後続管の敷設状況をも把握可能な方法及びその装置に関するものであり、主に８００ｍｍ以下の小口径管の推進工法において、特に急曲線の推進工法における位置計測に適したものである。 The present invention relates to a method and apparatus capable of grasping not only the position of the tip position but also the laying status of the subsequent pipe in real time in the propulsion method of the underground buried pipe. There are mainly suitable for position measurement in the propulsion method for small diameter pipes of 800 mm or less, particularly in the sharp curve propulsion method.
この小口径管の推進工法は、先端の掘進機で地中を掘削しながら当該掘進機の後方に推進管を次々と連結して同推進管の最後尾を発進立坑で押圧し、発進立坑から目標位置まで直進又は湾曲して推進する工法である。この工法において、先端の掘進機及び後続の推進管が地中を計画通り推進しているかどうか、これらの位置を計測し、方向修正しながら地中を推進させている。直線推進の場合は、発進立坑から、掘進機の背面にあるターゲットにレーザー光を照射してその位置を計測することが出来るが、近年、曲線推進施工のニーズが飛躍的に増している。このような曲線推進の位置計測として、現状の実施工で最も確立しているのは、電磁誘導方式である。 This small-diameter pipe propulsion method involves excavating the ground with the excavator at the tip and connecting the propulsion pipes one after another behind the excavator and pressing the tail end of the propulsion pipe with the start-up shaft. It is a method of propelling straight or curved to the target position. In this construction method, whether or not the tip excavator and the subsequent propulsion pipe are propelling through the ground as planned, these positions are measured, and the ground is propelled while correcting the direction. In the case of linear propulsion, the target can be measured by irradiating the target on the back of the excavator from the starting shaft, and its position can be measured, but in recent years, the need for curve propulsion construction has increased dramatically. As the position measurement of such curve propulsion, the electromagnetic induction method is most established in the current implementation.
この電磁誘導方式は、地中の推進ヘッド（ロッド）内に設置した発信器が発する磁力線を、地上の受信器で、最も強く受信する位置を測定して平面位置とし、その際の信号の強さから深度を演算処理して求めるものである。本方式は、海外で実績豊富な弧状推進工法（HDD-System）として一般的に用いられている位置計測方法で、計測方法が簡易で低コストであるが、計測には個人差がでやすい、計測のためには発信器の真上に行かなければならない、発信器と受信器の間に埋設管などの遮蔽物があると計測できない、計測精度があまり高くない、計測は先端位置のみの計測で、途中線形精度が不明（計測地点での測量結果を累積すれば可能であるが、推進後にはロッド復元力が働き、横滑り現象が生じ、計測時の座標と実質敷設位置とでは誤差がでる）、計測は一定の間隔で計測することになり、常に測量結果を反映させての方向制御が出来ない、等の問題点がある。 In this electromagnetic induction method, the line of magnetic force generated by a transmitter installed in a propulsion head (rod) in the ground is measured by the ground receiver at the position where it is most strongly received to obtain a plane position. Then, the depth is calculated and processed. This method is a position measurement method that is generally used as an arc-shaped propulsion method (HDD-System) with a proven track record overseas, and the measurement method is simple and low cost. For measurement, it must go directly above the transmitter, it cannot be measured if there is a shield such as an embedded pipe between the transmitter and the receiver, the measurement accuracy is not very high, the measurement is only at the tip position In the middle, linear accuracy is unknown (it is possible by accumulating the survey results at the measurement point, but after propulsion, the rod restoring force works, a skid phenomenon occurs, and there is an error between the coordinates at the time of measurement and the actual laying position ), The measurement is performed at regular intervals, and there is a problem that the direction control cannot always be performed while reflecting the survey result.
一方、３Ｄ曲がりセンサーによる先端ロッド曲がり量計測とチェーンド・ドライブジャイロによる削孔軌跡の併用測量方法は、前記電磁誘導方式の問題点を解決するべく弧状推進工法のドリルの方位、姿勢をドリルに近接して設けたセンサユニットにより計測するシステムを採用しており、また、ジャイロ製作技術の進化で究極に小型化されて直径６２ｍｍという極めて小型かつ高精度な位置計測を実現しており、ロッド回転時にも位置計測を行えるといった、工法に即した計測構造である。 On the other hand, the combined measurement method of the tip rod bending amount measurement by the 3D bending sensor and the drilling locus by the chained drive gyro makes the orientation and posture of the arc propulsion method drill to solve the problems of the electromagnetic induction method. The system uses a sensor unit installed in close proximity, and has been miniaturized by the evolution of gyro fabrication technology, realizing extremely small and highly accurate position measurement with a diameter of 62 mm, and rod rotation It is a measurement structure that conforms to the construction method so that position measurement can sometimes be performed.
しかし、この計測方法においても、機械式ジャイロ装置の径は６２ｍｍと小型であるが、長さが１９２５ｍｍであり、また、その材質も剛体であり、同ジャイロ装置箇所はロッド内空間とこのジャイロ装置の外径との間隙分しか曲げられず、この条件から最小曲率は３０ｍＲ程となり、急曲線の推進工法において要求される曲率（１０ｍＲ）の確保は困難である。また、曲線推進ではスプリングバックといわれる地中内で直線に戻ろうする力が加わり、横滑り現象が発生するが、こういった場合に測量精度に大幅な誤差を生じる。また、計測装置が非常に高価であるため施工費が高額となる最大要因となっている。 However, even in this measurement method, the mechanical gyro device has a small diameter of 62 mm, but the length is 1925 mm, and the material thereof is also a rigid body. The gyro device location is the space inside the rod and the gyro device. From this condition, the minimum curvature is about 30 mR, and it is difficult to secure the curvature (10 mR) required in the sharply curved propulsion method. Also, in the curve propulsion, a force that returns to a straight line in the ground, called springback, is applied and a skid phenomenon occurs. In such a case, a large error occurs in the surveying accuracy. Moreover, since the measuring device is very expensive, it is the biggest factor that increases the construction cost.
そこで、掘削すべきトンネルに沿って、所定の距離をおいて複数の測量定点を設定し、当該複数の測量定点を通過して折り曲がる測量用ワイヤを張架し、各測量定点において測量定点を中心として測量用ワイヤ検出手段を回転させ、測量用ワイヤ検出手段が最初に測量用ワイヤを検出したときの角度と次に測量用ワイヤを検出したときの角度とから各測量定点において測量用ワイヤがなす折れ角度を求め、当該折れ角度と前記所定の距離から各測量定点の位置を求める、小口径の推進工法に適したカーブ測量方法が開発されている。
また。上記と同様に推進管内に継線（ワイヤ）を通し、前後の継線のなす継線角度を継線角度測定器で測定し、推進管のローリングによって発生する傾いた状態の継線角度を水平面に投影した投影角度を継線角度とする補正を行って、継線角度と継線長さから継線のｘ成分の総和と継線のｙ成分の総和から掘進機の位置を求めるようにした推進工法における掘進機位置の測定方法が開発されている。
Also. In the same way as above, a connecting line (wire) is passed through the propulsion pipe, the connecting angle between the front and rear connecting lines is measured with a connecting angle measuring instrument, and the inclined connecting angle generated by rolling the propelling pipe is measured in the horizontal plane. The position of the digging machine is obtained from the sum of the x component of the joint and the sum of the y component of the joint from the joint angle and the joint length. A method for measuring the position of the excavator in the propulsion method has been developed.
しかしながら、上記前者のカーブ測量方法は小口径管の中にワイヤを通し、所定の距離をおいた測量定点で当該ワイヤの折れ角度を求め、上記所定の距離から各測量定点の位置を求めていって、先端の掘進機の位置を計測するため、小口径推進には適したものであるが、各測量定点でのワイヤの折れ角度の測定が、平面的であり、三次元的に折れ曲がった角度や方向を計測することはできない。また、各測量定点で測量用ワイヤ検出手段によりワイヤの折れ角度を測定する場合、測量用ワイヤ検出手段を各測量定点に移動させなければならない。従って、計測に手間がかかると同時に時間もかかる欠点を有している。また、後者の掘進機位置の測定方法は、継線と継線角度測定器を用いる複雑な計測により掘進機の位置を求めるものであり、掘進機の後続の推進管全体の位置まで計測するものではない。 However, in the former curve surveying method, a wire is passed through a small-diameter tube, the bending angle of the wire is determined at a surveying fixed point at a predetermined distance, and the position of each surveying fixed point is determined from the predetermined distance. It is suitable for small-diameter propulsion because it measures the position of the excavator at the tip, but the measurement of the wire bending angle at each surveying fixed point is planar and the angle bent three-dimensionally And the direction cannot be measured. Further, when the wire break angle is measured by the surveying wire detection means at each surveying fixed point, the surveying wire detection means must be moved to each surveying fixed point. Therefore, there is a drawback that it takes time and time for measurement. In addition, the latter method for measuring the position of the excavator is to determine the position of the excavator by complicated measurement using a connecting line and a connecting angle measuring device, and to measure the position of the entire propulsion pipe following the excavator. is not.
この発明はこれらの点に鑑みて為されたもので、複数接続された推進管の中にワイヤを通し、所定間隔で当該ワイヤを支持し、これらのワイヤの各支持点で、当該ワイヤの折れ角度を三次元的に計測でき、かつ、即座に各支持点の折れ角度と各支持点の距離からこれらの推進管全体の位置を計測できる、推進工法用位置計測方法及びこれに使用する装置を提供し上記課題を解決しようとするものである。 The present invention has been made in view of these points. A wire is passed through a plurality of connected propulsion pipes, the wire is supported at predetermined intervals, and the wire is bent at each support point of these wires. A position measuring method for a propulsion method and an apparatus used therefor, which can measure the angle three-dimensionally and can immediately measure the position of each propelling pipe from the bending angle of each supporting point and the distance between the supporting points. It is intended to solve the above problems.

以下この発明を図面に基づいて説明する。
図１はこの発明の推進工法用位置計測方法の概略構成図を示すもので、まず、推進工法は、図１に示すように、先端の掘進機１で地中を掘削しながら当該掘進機１の後方に一定長の推進管２を次々と連結して同推進管２の最後尾を発進立坑３に設けた押圧装置４により押圧し、発進立坑３から目標位置まで直進又は湾曲して推進する工法である。そしてこの工法に使用する位置計測方法には、上記掘進機１の後部に測定用ワイヤ５の一端を固定し、他端を後続の複数の推進管２内に、各推進管２とほぼ平行に通し、最後尾の推進管２から発進立坑３に導出して当該発進立坑３内でテンション装置６により当該測定用ワイヤ５に一定の張力をかけておく。そして、当該測定用ワイヤ５は、各推進管２内の一端部で支持させる。当該測定用ワイヤ５の各支持は、各推進管２の内側に支持された支持体７により、ワイヤの長手方向に摺動自在かつ当該長手方向に直角な方向に揺動自在に上記測定用ワイヤ５を遊通させており、これらの各支持体７箇所で、測定用ワイヤ５の折れ角度及び方向を計測する構成となっている。
The present invention will be described below with reference to the drawings.
FIG. 1 shows a schematic configuration diagram of a position measuring method for a propulsion method according to the present invention. First, as shown in FIG. 1, the propulsion method is performed by excavating the ground with the excavator 1 at the tip. A certain length of the propulsion pipe 2 is connected to the back of the pipe one after another, and the rear end of the propulsion pipe 2 is pressed by a pressing device 4 provided on the start shaft 3, and propelled straight from the start shaft 3 to a target position. It is a construction method. In the position measuring method used in this construction method, one end of the measuring wire 5 is fixed to the rear portion of the excavator 1, and the other end is placed in a plurality of succeeding propulsion pipes 2 substantially parallel to the respective propulsion pipes 2. Then, it is led out from the last propelling pipe 2 to the starting shaft 3 and a certain tension is applied to the measuring wire 5 by the tension device 6 in the starting shaft 3. The measurement wire 5 is supported at one end in each propulsion pipe 2. Each support of the measurement wire 5 is supported by the support body 7 supported on the inside of each propulsion tube 2 so as to be slidable in the longitudinal direction of the wire and swingable in a direction perpendicular to the longitudinal direction. 5 is configured such that the bending angle and direction of the measuring wire 5 are measured at these seven support members.
図２及び図３は、上記支持体７の具体例を示す、一部切欠斜視図及び縦断面図である。この支持体７は、複数のスペーサ８を介在させて一定間隔のフランジ９を二枚相対向して設け、これらのフランジ９、９の相対向する内面に、二つの同径の管体１０、１０を相対向して設け、これらの各管体１０の先端は一定の間隔をあけ、上記管体１０、１０の上下左右の位置に、各管体１０の外周から一定幅離れてゲージプレート１１を夫々設け、これらの４枚のゲージプレート１１は上記二枚のフランジ９と９の間に渡され支持されている。また、これらのゲージプレート１１の各外面には歪みゲージ１２が設けられている。さらに、上記管体１０と１０の先端の間隙に、中心孔１３ａを有する円板１３が挿入され、当該円板１３は、上記４枚のゲージプレート１１に囲まれているが、円板１３の外周と各ゲージプレート１１の内面との間に隙間を有している。また、上記スペーサ８の一つに、回転角度計１８を設けている。 2 and 3 are a partially cutaway perspective view and a longitudinal sectional view showing a specific example of the support 7. This support body 7 is provided with a plurality of spaced flanges 9 with a plurality of spacers 8 interposed therebetween, and two flanges 9, 9 having two same diameter pipes 10, 10 are provided opposite to each other, and the tips of the tube bodies 10 are spaced apart from each other by a certain distance, and at the vertical and horizontal positions of the tube bodies 10, 10, the gauge plate 11 is spaced apart from the outer periphery of the tube bodies 10 by a certain width. These four gauge plates 11 are passed between and supported by the two flanges 9 and 9. A strain gauge 12 is provided on each outer surface of these gauge plates 11. Further, a disc 13 having a center hole 13a is inserted into the gap between the ends of the tubular bodies 10 and 10, and the disc 13 is surrounded by the four gauge plates 11. There is a gap between the outer periphery and the inner surface of each gauge plate 11. A rotation angle meter 18 is provided on one of the spacers 8.
そして、上記測定用ワイヤ５はこの支持体７の上記一方のフランジ９に開口部を有する一方の管体１０から挿入され、円板１３の中心孔１３ａを通り、他方の管体１０を通って他方のフランジ９の開口部から外方に抜けている。従って、測定用ワイヤ５は、上記円板１３の中心孔１３ａに挿通されているが、長手方向に摺動自在であり、当該長手方向に直角な面方向に対しては円板１３の外周が四方のゲージプレート１１のいずれかの内面に当たるまで、移動自在となっている。 The measurement wire 5 is inserted from one tube 10 having an opening in the one flange 9 of the support 7, passes through the central hole 13 a of the disk 13, and passes through the other tube 10. The other flange 9 is pulled out from the opening. Accordingly, the measuring wire 5 is inserted through the center hole 13a of the disk 13, but is slidable in the longitudinal direction, and the outer periphery of the disk 13 is not perpendicular to the surface direction perpendicular to the longitudinal direction. It is movable until it hits one of the inner surfaces of the four gauge plates 11.
従って、接続された二つの推進管２が一方に対して折れ曲がると、測定用ワイヤが折れ曲がり、その挙動方向により上記円板１３が一つ又は複数のゲージプレート１１を押圧して荷重をかけ、当該荷重がかかったゲージプレート１１の歪みゲージ１２が歪む。そこで、この歪みゲージ１２の示す歪み量と荷重がかかった歪みゲージ１２の位置を検出する。この歪みゲージ１２の歪み量により測定用ワイヤ５の折れ角度を検出しようとするものであるが、この歪み量は測定用ワイヤ５の張力によって異なる。そこで、張力値と歪みゲージの歪み量との関係を予め算出しておく。そして当該支持体７箇所の測定用ワイヤ５の張力を計測する。各推進管２の長さが決まっているため、発進立坑３から当該支持体７までの測定用ワイヤ５の長さが分かる。また、発進立坑３で当該測定用ワイヤ５の張力値Ｆｔを測定する。この張力値Ｆｔを基に各支持体７までの距離によって減衰した値を算出し、図１に示す各支持体７箇所の張力Ｆθ１、Ｆθ２、Ｆθ３が得られ、これらの得られたＦθを基にして、上記歪みゲージ１２の歪み量から計算により各支持体７箇所での測定用ワイヤ５の折曲角度θ１、θ２、…θｎを得ることが出来る。 Therefore, when the two connected propulsion pipes 2 are bent with respect to one side, the measuring wire is bent, and the disc 13 presses one or a plurality of gauge plates 11 according to the behavior direction to apply a load. The strain gauge 12 of the loaded gauge plate 11 is distorted. Therefore, the strain amount indicated by the strain gauge 12 and the position of the strain gauge 12 to which a load is applied are detected. The bending angle of the measuring wire 5 is to be detected based on the strain amount of the strain gauge 12, but this strain amount varies depending on the tension of the measuring wire 5. Therefore, the relationship between the tension value and the strain amount of the strain gauge is calculated in advance. And the tension | tensile_strength of the measurement wire 5 of the said support body 7 location is measured. Since the length of each propulsion pipe 2 is determined, the length of the measurement wire 5 from the start shaft 3 to the support 7 can be known. Moreover, the tension value Ft of the measurement wire 5 is measured at the start shaft 3. Based on this tension value Ft, the value attenuated by the distance to each support 7 is calculated, and the tensions Fθ1, Fθ2, Fθ3 of each support 7 shown in FIG. 1 are obtained, and these obtained Fθ are used as the basis. Thus, the bending angles θ1, θ2,... Θn of the measuring wire 5 at each of the seven support members can be obtained by calculation from the strain amount of the strain gauge 12.
なお、また、折れ曲がり方向は、上記荷重のかかった歪みゲージ１２の位置から検出できる。その際、上記支持体７に回転角度計１８を設けているため、当該支持体７の推進管２のローリング状態が分かり、上記荷重のかかった歪みゲージ１２の位置を補正できる。また各支持点（支持体７）までの距離は、上述のように、推進管２の長さＬが分かっているため算出できる。これにより、各支持点での折れ角度及び方向、及び発進立坑３から各支持点までの距離がわかるため、推進座標を計算推測することができる。なお、この実施例においても、上記各支持体７箇所ごとに張力計を設けて当該箇所の測定用ワイヤ５の張力を測定し、この張力値に基づいて歪みゲージ１２の歪み量から折れ角度を計測することも出来る。 In addition, the bending direction can be detected from the position of the strain gauge 12 to which the load is applied. At this time, since the rotation angle meter 18 is provided on the support 7, the rolling state of the propulsion tube 2 of the support 7 can be known, and the position of the strain gauge 12 subjected to the load can be corrected. Further, the distance to each support point (support 7) can be calculated because the length L of the propulsion pipe 2 is known as described above. As a result, the folding angle and direction at each support point and the distance from the start shaft 3 to each support point can be known, so that the propulsion coordinates can be calculated and estimated. In this embodiment as well, a tension meter is provided for each of the above seven support members to measure the tension of the measurement wire 5 at that position, and the bending angle is determined from the strain amount of the strain gauge 12 based on this tension value. It can also be measured.
図４は、上記支持体７の他の具体例を示す側面図である。この支持体７´は上記推進管２の内周に固定した支持管体１６内に、中央にフランジ１５ａを有する横長の軸からなる接続体１５を挿入して、上記フランジ１５ａを上記支持管体１６の内周に摺動自在に支持させ、当該支持点で測定用ワイヤ５を分断し、これらの分断端部を上記接続体１５の両端で連結し、上記支持管体１６内の接続体１５の、フランジ１５ａを挟んだ一方の側の軸の外周上下左右の４箇所に歪みゲージ１２を設け、また、フランジ１５ａを挟んだ他方の側の軸の外周の相対向する面に２枚の引張り力検出歪みゲージ１７を設け、さらに当該他方の側の軸の外周に回転角度計１８を設けたものである。 FIG. 4 is a side view showing another specific example of the support 7. The support body 7 'is inserted into a support tube body 16 fixed to the inner periphery of the propulsion tube 2, and a connecting body 15 comprising a horizontally long shaft having a flange 15a at the center is inserted, and the flange 15a is inserted into the support tube body. 16 is slidably supported on the inner periphery of 16, the measurement wire 5 is divided at the support point, and these divided ends are connected at both ends of the connection body 15, so that the connection body in the support tube body 16 is connected. 15, strain gauges 12 are provided at four locations on the outer circumference of the shaft on one side across the flange 15a, and two on the opposite surfaces of the outer circumference of the shaft on the other side across the flange 15a. A tensile force detection strain gauge 17 is provided, and a rotation angle meter 18 is provided on the outer periphery of the other shaft.
この支持体７´は、図４の左側を発進立坑３側に、右側を掘削機１側に接続し、掘進機１側の前方の推進管２が折れ曲がると測定用ワイヤ５が折れ曲がり、それに続くフランジ１５ａを挟んだ歪みゲージ１２を有する接続体１５の一側が歪み、上下左右にある歪みゲージ１２の一つ又は複数の歪みゲージ１２が歪む。これにより歪んだ歪みゲージ１２の歪み量と歪み位置を検出し、上記フランジ１５ａを挟んだ接続体１５の他側の引張り力検出歪みゲージ１７により測定した、隣接する他の支持体７´との間の張力値を勘案して、当該接続体７´箇所の測定用ワイヤ５の折れ角度及び方向を検出する。さらに回転角度計１８により当該推進管２のローリング状態を検出し、発進立坑３からの当該支持体７´間での距離により、当該距離と上記角度及び方向で推進座標を計算推測することができる。また、このように各支持体７´箇所で測定用ワイヤ５の張力値及び歪みゲージの歪み量を検出し、当該支持点箇所にコンピュータを設ければ（図示省略）、その場所で測定用ワイヤ５の折れ曲がり角度及び方向を計測することができ、従って当該コンピュータの出力用の配線のみを導出すればよい。 This support 7 'is connected to the start shaft 3 side on the left side of FIG. 4 and to the excavator 1 side on the right side. When the propulsion pipe 2 on the front side of the excavator 1 is bent, the measuring wire 5 is bent, and the following. One side of the connecting body 15 having the strain gauge 12 sandwiching the flange 15a is distorted, and one or more strain gauges 12 of the strain gauges 12 on the top, bottom, left and right are distorted. Thus, the strain amount and strain position of the strain gauge 12 which has been distorted are detected, and measured with the tensile force detection strain gauge 17 on the other side of the connection body 15 sandwiching the flange 15a. In consideration of the tension value between them, the bending angle and direction of the measuring wire 5 at the location of the connecting body 7 'are detected. Further, the rotation state of the propulsion pipe 2 can be detected by the rotation angle meter 18, and the propulsion coordinates can be calculated and estimated based on the distance, the angle and the direction, based on the distance between the support shaft 7 ′ from the start shaft 3. . Further, if the tension value of the measurement wire 5 and the strain amount of the strain gauge are detected at each support 7 ′ position and a computer is provided at the support point position (not shown), the measurement wire is located at that position. 5 bend angles and directions can be measured, so only the output wiring of the computer need be derived.
