Description

この発明は、鉄道線路のレールに現れる変位を監視しその変位量を計測する鉄道線路の変位計測方法と、その鉄道線路の変位計測方法でレールの変位を測定するための鉄道線路変位計測装置に関するもので、殊に、線路下にトンネルを横断構築するような、線路に近接した土木・建設工事に起因してレールに現れる所謂「通り狂い」の変位（レール軌間方向にレールが移行する変位）の計測方法と計測定装置に関するものである。  The present invention relates to a railroad track displacement measuring method for monitoring the displacement appearing on the railroad rail and measuring the amount of displacement, and a railroad track displacement measuring device for measuring the rail displacement by the railroad track displacement measuring method. In particular, the so-called “passing” displacement (displacement in which the rail moves in the direction of the rail gauge) that appears on the rail due to civil engineering and construction work close to the rail, such as crossing a tunnel under the rail The present invention relates to a measuring method and a measuring device.

レーザ変位計測器を用いて鉄道レールの変位を監視しその変位量を計測する方法・装置が従来から種々提案されている。例えば、特開２００２−４６６０５号公開特許公報（特許文献１）には、鉄道軌道に沿って設置されたレーザ変位計からレーザ光を鉄道軌道に照射することにより、軌道の異常変位を検出して保線区間管理所に警報を発することが示されている。また特開２００６−３０８３０４号公開特許公報（特許文献２）には、計測対象の軌道区間の一端にレーザ距離計を配置し、他端にはレーザ距離計からのレーザ光を受光して受光信号を出力する受光手段を配置し、さらに軌道区間の中点に、軌道と直交する方向に出没駆動される光遮断片を出没駆動する送り装置を配置し、その送り装置によって出没駆動される光遮断片が、レーザ距離計から受光手段までの光路を遮断するときの出没運動量に基づいて、軌道区間の「通り狂い」を計測する装置が示されている。他方、特許第３７８０３７７号特許公報（特許文献３）に示されるように、地盤の二つ不動点の間に張設したワイヤーを変位計測箇所に接近させて配設し、そのワイヤーと変位計測箇所の間の間隔を非接触型変位センサで検出して、その変位計測箇所の変位を高い精度で計測する方法・装置が提案されている。
特開２００２−４６６０５号公開特許公報 特開２００６−３０８３０４号公開特許公報 特許第３７８０３７７号特許公報 Various methods and apparatuses for monitoring the displacement of railway rails using a laser displacement measuring instrument and measuring the amount of displacement have been proposed. For example, Japanese Patent Laid-Open No. 2002-46605 (Patent Document 1) discloses that an abnormal displacement of a track is detected by irradiating a railroad track with laser light from a laser displacement meter installed along the railroad track. It is shown that a warning is issued to the track section management office. In Japanese Patent Laid-Open No. 2006-308304 (Patent Document 2), a laser distance meter is disposed at one end of a track section to be measured, and the other end receives a laser beam from the laser distance meter to receive a light signal. Is disposed at the midpoint of the track section, and a light blocking device that is driven to move in and out in a direction perpendicular to the track is arranged, and the light blocking that is driven by the feeding device is arranged. A device is shown that measures the “traversed” of the orbital section based on the amount of movement that appears when the piece interrupts the optical path from the laser distance meter to the light receiving means. On the other hand, as shown in Japanese Patent No. 3780377 (Patent Document 3), a wire stretched between two fixed points of the ground is disposed close to the displacement measurement location, and the wire and the displacement measurement location are arranged. A method / apparatus has been proposed in which the distance between the two is detected by a non-contact type displacement sensor and the displacement at the displacement measurement point is measured with high accuracy.
Japanese Patent Laid-Open No. 2002-46605 Japanese Patent Laid-Open No. 2006-308304 Japanese Patent No. 3780377

昨今、鉄道輸送の安全性の維持向上を第一義にしながら、鉄道輸送のスピード化、効率化を進める上で、鉄道線路のレールの変位を、簡易な手段でもって高い精度で監視し計測することが求め続けられており、特に線路の近辺で行われる近接土木・建設工事に起因して生ずるレールの挙動を直接計測し把握することが強く求められている。その中で次のような計測性能が要求されている。
（１）水平変位あるいは垂直変位について、１ｍｍオーダーの信頼できる情報が得られること．
（２）計測結果は、即時にビジュアル且つ定量的な情報として得られること．
（例えば、２分間隔の高い列車通過密度の中で、変位測定−測定データ分析−分析結果表示−変位の評価・判断のサイクルが満足されること．）
（３）長時間の連続計測に耐え、継続的に安定した情報が得られること．
（４）計測機器類は、建築限界に支障とならないようにコンパクトで、線路保線作業への支障が少ないこと．In recent years, with the primary focus on maintaining and improving the safety of rail transport, the speed and efficiency of rail transport are promoted, and the rail displacement of railroad tracks is monitored and measured with simple means with high accuracy. In particular, there is a strong demand to directly measure and understand the behavior of rails caused by close civil engineering / construction work in the vicinity of railway tracks. Among them, the following measurement performance is required.
(1) Reliable information on the order of 1 mm can be obtained for horizontal displacement or vertical displacement.
(2) Measurement results should be obtained as visual and quantitative information immediately.
(For example, the cycle of displacement measurement-measurement data analysis-analysis result display-displacement evaluation / judgment must be satisfied in a high train passage density at intervals of 2 minutes.)
(3) Withstand continuous measurement over a long period of time and obtain stable information continuously.
(4) The measuring equipment must be compact so as not to hinder the building limits, and there should be few obstacles to track maintenance work.

また、従来の鉄道線路のレールの変位計測方法・装置では、近接土木・建設工事に起因する変位と、近接土木・建設工事以外の事象によって線路を支える地盤に生じた変位との関係が峻別できないという問題点も現存している。  In addition, in the conventional rail track rail displacement measurement method and apparatus, the relationship between the displacement caused by the adjacent civil engineering / construction work and the displacement generated on the ground supporting the track due to an event other than the neighboring civil engineering / construction construction cannot be distinguished. There is also a problem that.

そして前記特許文献１，２，３に示されるような従前の変位監視・計測システムでは、上記のような計測性能がなお満たされず、近接土木・建設工事に起因する変位と、線路を支える地盤の他の事象に起因する変位との峻別もできないことから、この発明では、上記のような性能要求に応えると共に、近接土木・建設工事に起因する変位と、他の事象に起因する地盤変位とを峻別可能な鉄道線路の変位計測方法および鉄道線路変位計測装置を提供しようとするものである。  In the conventional displacement monitoring / measurement system as shown in Patent Documents 1, 2, and 3, the above-described measurement performance is not yet satisfied, and the displacement caused by the nearby civil engineering / construction work and the ground supporting the track Since it cannot be distinguished from displacement caused by other events, the present invention responds to the performance requirements as described above, and includes displacement caused by close civil engineering / construction work and ground displacement caused by other events. It is an object of the present invention to provide a railway track displacement measuring method and a railway track displacement measuring apparatus which can be distinguished.

上記のような性能要求あるいは課題・目標に応ずるために、この発明では、水路式変位計測装置と既に周知のレーザ変位計測器を併用し、その水路式変位計測装置を、鉄道線路のレールの変位測定区間に沿わせて配設し、そのレールの変位計測区間に設定された複数の変位計測点のそれぞれに対して、上記水路式変位計測装置の変位計測点貯液槽の一つとレーザ変位測定器をそれぞれ対向させると共に、上記レールの変位計測区間に設定された複数の変位計測点に位置するレール側面にレーザ光を反射させるレーザターゲットを装着し、このレーザターゲットに向けて同変位計測点に対向したレーザ変位測定器からレーザ光を照射し、そのレーザ反射光を同レーザ変位計測器で受光し、その反射光の時間差からレールの通り狂い変位を計測すると同時に、鉄道線路の基盤をなす地盤の変位をも同時に計測することを特徴とする。  In order to meet the above performance requirements or problems / targets, in the present invention, a water channel displacement measuring device is used in combination with a known laser displacement measuring device, and the water channel displacement measuring device is used as a rail displacement of a railroad track. Laser displacement measurement with one of the displacement measurement point reservoirs of the above-mentioned channel-type displacement measurement device for each of a plurality of displacement measurement points set along the measurement interval and set in the displacement measurement interval of the rail A laser target that reflects laser light is attached to the rail side surface located at a plurality of displacement measurement points set in the displacement measurement section of the rail, and the displacement measurement point is directed toward the laser target. Laser light is emitted from the opposed laser displacement measuring device, the reflected laser light is received by the laser displacement measuring device, and the rail displacement deviation is measured from the time difference of the reflected light. At the same time, characterized by measuring at the same time the displacement of the ground the foundation of the railway track.

そして、この発明によれば、上記の解決手段により、レールの水平変位あるいは垂直変位に関して、高い信頼性をもった精度高い情報が得られ、高い列車通過密度の中で、レールの変位に関する定量的なビジュアルな判断情報が即時に得られ、長時間にわたって継続的に安定した情報が得られ、また、コンパクトな計測機器を用いることができて建築限界や線路保線作業に対する支障も少なく、更にまた、近接土木・建設工事に起因する変位と、近接土木・建設工事以外の事象によって線路を支える地盤に生じた変位との関係も峻別できるという優れた効果を奏するものである。  According to the present invention, the above solution can provide highly reliable information with high reliability regarding the horizontal displacement or vertical displacement of the rail, and quantitatively relate to the displacement of the rail in a high train passage density. Visual judgment information can be obtained immediately, stable information can be obtained continuously over a long period of time, and a compact measuring device can be used, so there are few obstacles to construction limits and track maintenance work. There is an excellent effect that the relationship between the displacement caused by the adjacent civil engineering / construction work and the displacement generated in the ground supporting the track by an event other than the neighboring civil engineering / construction work can be distinguished.

レール１，２は枕木３とパラスト道床（図示省略）を介して、天然の地盤を整地して生成した路盤（図示省略）上に敷設され鉄道線路（略して「線路」という）が構築されている。その線路の近くで土木・建設工事が行われると、線路の各部に様々な歪みが生じて所謂「線路狂い」が発生する可能性があり、この「線路狂い」が大きくなると、鉄道輸送の安全性が大きく損なわれることになる。殊に例えば、鉄道線路下にトンネルを横断貫通させるような線路近接工事においては、その工事に起因して、レールに所謂「通り狂い」が生ずる可能性が高い。「通り狂い」は、レールの軌間方向にレールが変位する現象で、線路の安全管理上の重要な監視項目の一つである。したがって、レールの「通り狂い」変位を計測し監視して、必要に応じて安全対策を講ずることは極めて重要である。図１は、「通り狂い」変位によってレール１，２が湾曲した状態を示しており、図１中に２点鎖線の直線で示した位置はレール１，２の当初の正常な位置を示し、図１中の長さＬ１はレール１の変位量（通り狂い）を示している。  Rails 1 and 2 are laid on a roadbed (not shown) generated by leveling natural ground through sleepers 3 and a parast roadbed (not shown), and a railroad track (abbreviated as “track”) is constructed. Yes. If civil engineering / construction work is performed near the track, various distortions may occur in each part of the track, which may cause a so-called `` track error ''. The nature will be greatly impaired. In particular, for example, in a railway close construction such as traversing a tunnel under a railroad track, there is a high possibility that a so-called “trailing error” occurs in the rail. “Travel” is a phenomenon in which the rail is displaced in the direction between the rails, and is one of the important monitoring items in the safety management of the track. Therefore, it is very important to measure and monitor the rails' “wrong” displacement and to take safety measures as necessary. FIG. 1 shows a state in which the rails 1 and 2 are curved due to the “passing” displacement, and the position indicated by the two-dot chain line in FIG. 1 indicates the initial normal position of the rails 1 and 2. The length L1 in FIG. 1 indicates the amount of displacement (passage) of the rail 1.

The location and length (for example, several tens of meters) of the displacement measurement section S are set according to the scale and situation of the track proximity construction, and several displacements are included in the displacement measurement section. Measurement points P1, P2, P3, P4 and P5 are set. The interval between adjacent displacement measurement points is set to several meters, for example. In the rail 1, laser targets T1, T2, T3, T4, and T5 are mounted on the outer side surfaces of the positions located at the displacement measurement points P1, P2, P3, P4, and P5. As will be described later, the laser targets T1, T2, T3, T4, and T5 are irradiated with laser light from a laser displacement measuring device, and the laser light is emitted from the laser targets T1, T2, T3, T4, and T5. It is reflected toward the displacement measuring instrument.

Ｗは水路式変位計で、その詳細は前記特許文献（特許第３７８０３７７号特許公報）に示されるところである。すなわち水路式変位計Ｗは、図１，３，４に示すように、土木・建設現場から遠く離れて土木・建設工事に伴う地盤変位が及ばない２箇所の不動点にそれぞれ設置された不動点貯液槽２１と両不動点貯液槽の間に位置して、液路２３を介して両不動点貯液槽２１と共に一連に縦続連結された複数の変位計測点貯液槽２２と、不動点貯液槽２１、変位計測点貯液槽２２および液路２３に貯留された液体２９と、その液体２９中にあってこれらの液路２３および変位計測点貯液槽２２を貫通して両不動点間に架設されたワイヤー２７と、前記変位計測点貯液槽２２内にあって前記ワイヤーと、前記変位計測点貯液槽２２の相対変位を感知・計測する変位センサ３０，３１を備えてなる。そしてこの発明にかかる鉄道線路の変位計測方法・装置は、この水路式変位計測装置と既に周知のレーザ変位計測器２４を併用し、レール１の変位計測区間Ｓに沿って前記一連の変位計測点貯液槽２２と液路２３を配設し、同レールの変位計測区間Ｓに設定された複数の変位計測点Ｐ１，Ｐ２，Ｐ３，Ｐ４，Ｐ５のそれぞれに前記変位計測点貯液槽２２の一つとレーザ変位測定器２４を対応させて対向させ、そのレールの変位計測区間Ｓに設定された複数の変位計測点Ｐ１，Ｐ２，Ｐ３，Ｐ４，Ｐ５におけるレール１の側面に装着したレーザターゲットに向けてレーザ変位測定器２４からレーザ光を照射してその反射光を受光してその反射光の時間差からレールの通り狂い変位を計測すると同時に、鉄道線路の基礎をなす地盤変位をも同時に計測するものである。なお、Ｎはレールに対する建築限界を示している。   W is a water channel displacement meter, the details of which are shown in the patent document (Japanese Patent No. 3780377). That is, as shown in FIGS. 1, 3, and 4, the waterway type displacement meter W is installed at two fixed points that are far from the civil engineering / construction site and are not affected by ground displacement due to the civil engineering / construction work.

A wire 27 installed between fixed points; displacement sensors 30 and 31 in the displacement measurement point storage tank 22 for detecting and measuring relative displacement of the wire and the displacement measurement point storage tank 22; It becomes. The railroad track displacement measuring method and apparatus according to the present invention uses the water channel displacement measuring device and the already known laser displacement measuring device 24 together, and the series of displacement measuring points along the displacement measuring section S of the rail 1. A liquid storage tank 22 and a liquid path 23 are provided, and the displacement measurement point storage tank 22 is disposed at each of a plurality of displacement measurement points P1, P2, P3, P4, and P5 set in the displacement measurement section S of the rail. A laser target is mounted on the side of the rail 1 at a plurality of displacement measurement points P1, P2, P3, P4, and P5 set in the displacement measurement section S of the rail. The laser displacement measuring device 24 irradiates the laser beam, receives the reflected light, and measures the rail displacement displacement from the time difference of the reflected light. At the same time, the ground displacement that forms the basis of the railway track is also measured. It is intended to measure. N indicates the construction limit for the rail.

上記の実施例からも明らかなように、この発明によれば、レールの変位に関して、高い信頼性をもった精度高い情報が得られ、高い列車通過密度の中で、レールの変位に関する定量的なビジュアルな判断情報が即時に得られ、長時間にわたって継続的に安定した情報が得られ、また、コンパクトな計測機器を用いることができて建築限界や線路保線作業に対する支障も少なく、更にまた、近接土木・建設工事に起因する変位と、近接土木・建設工事以外の事象によって線路を支える地盤に生じた変位との関係も峻別できるので、種々の産業分野において、その利用の可能性は極めて大きいと考えられる。  As is clear from the above-described embodiments, according to the present invention, highly accurate information with high reliability can be obtained regarding the rail displacement, and the quantitative information regarding the rail displacement can be obtained in a high train passage density. Visual judgment information can be obtained immediately, stable information can be obtained continuously over a long period of time, and compact measuring equipment can be used, so there are few obstacles to building limits and track maintenance work.
