【発明の詳細な説明】
本発明は小口径管（φ２００〜２５０ ［）及び超小口
径管（φ７０〜１５０ｍ）の推進機械の上下位置計測装
置に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vertical position measuring device for propulsion machines for small diameter pipes (φ200 to 250 m) and ultra small diameter pipes (φ70 to 150 m).
従来小口径管推進においては、方向修正して管を直線状
に布設する必要から先導管の位置を計測して推進を行っ
ていた。Conventionally, in small-diameter pipe propulsion, the position of the leading pipe was measured and propulsion was performed because it was necessary to correct the direction and lay the pipe in a straight line.

に埋設管ｃｆ推進埋設していたのである。In other words, a vertical shaft as shown in Figure 1! The conductor installed inside the leading pipe C was observed from the hollow part d of the buried pipe C at A, the position was measured, and the buried pipe CF was propulsion buried in a straight line. .
しかし、超小口径管を埋設する場合は、管径が細く、管

、ターケットｆ’ｃ観測することは不可能であって、精
度よい推進ができなかつ几。However, when burying an ultra-small diameter pipe, the diameter of the pipe is small and power hoses and cables for controlling the direction of the lead pipe e, such as hydraulic hoses, are built into the pipe, so the cavity d is usually blocked and the target It is impossible to observe f'c, and precise propulsion is not possible.
また、小口径管（φ２００〜２５０ ｍ１ｍ）の埋設の
場合でも曲進して埋設を行う場合は、管が直線状でなく
なｐ、トランミツトｂによる光学的計測はできなかった
。Furthermore, even in the case of burying a small diameter pipe (φ200 to 250 m1m), if the pipe is buried in a curved manner, the pipe is no longer in a straight line and optical measurement using the transmit b is not possible.

推進機械の上下位置計測装ｆ１ｔを提供することにある
。The present invention was developed in view of the above circumstances, and its purpose is to accurately measure the vertical position of a leading pipe even when the buried pipe is thin or curved. Another object of the present invention is to provide a device for measuring the vertical position of a propulsion machine, which is capable of constantly discharging liquid overflowing from the opening of a tank to the shaft side. To provide a vertical position measuring device f1t for a propulsion machine, which makes it possible to quickly know that liquid has overflowed from an opening of a pipe and to quickly measure the position of a leading pipe.
以下、本発明を第２図以下を参照して説明する。Hereinafter, the present invention will be explained with reference to FIG. 2 and subsequent figures.
図面中１は立坑があり、２は埋設管、３は先導管でおる
。先導管３内にはタンク４が設けてあり、立坑１内には
マノメータ５が設けである。In the drawing, 1 is a vertical shaft, 2 is a buried pipe, and 3 is a leading pipe. A tank 4 is provided within the leading pipe 3, and a manometer 5 is provided within the shaft 1.
そして、タンク４の側部の接続口９は管体７を介してマ
ノメータ５の管部８に接続しである。The connection port 9 on the side of the tank 4 is connected to the tube portion 8 of the manometer 5 via the tube body 7.
タンク４は開口部６を上面に備えていて常に大気に開放
状態になっている。The tank 4 has an opening 6 on its upper surface and is always open to the atmosphere.
したがって、マノメータ５の出口１０とタンク４内は同
一圧力状態になっており、そのためタンク４の液位とマ
ノメータ５の液位は同一液位になっている。Therefore, the outlet 10 of the manometer 5 and the inside of the tank 4 are in the same pressure state, and therefore the liquid level in the tank 4 and the liquid level in the manometer 5 are the same liquid level.
先導管３が下方に移動するとタンク４は下方に移動し第
３図に点線に示す如くなる。When the leading pipe 3 moves downward, the tank 4 moves downward as shown by the dotted line in FIG.
このためにマノメータ５の液位は下がシ液体はタンク４
に移動する。For this reason, the liquid level on manometer 5 is lowered, and the liquid level on tank 4 is lower.
Move to.
タンク４の底面積をＳ、マノメータ５の管断面積をαと
して先導管３０基準位ｆｌ、からのずれｆｘとし、マノ
メータ５０基準位置からのずれをｔとすると、液位の上
昇部６は
２ ・ α 冨 δ ・ Ｓ
から求まシ、また先導管２０基準位置からのずれＸは
ｘ ＝ Ｌ ＋ｄ
である。したがって
ｘ−（１＋−）・ｌ
となシ、マノメータ５の液位から２の値は換算できる。If the bottom area of the tank 4 is S, the pipe cross-sectional area of the manometer 5 is α, the deviation from the leading pipe 30 reference position fl is fx, and the deviation from the manometer 50 reference position is t, the liquid level rising portion 6 is 2. - Determined from α, δ, and S, and the deviation X from the reference position of the leading pipe 20 is x = L + d. Therefore, the value of 2 can be converted from the liquid level of the manometer 5 as x-(1+-)·l.
仮に’／Ｉ ＜＜１ならＸ中ｌとしても差しつかえない
。If '/I <<1, then it is okay to use l in X.
また、計測時にマノメータ５の出口は１０から水を供給
し、タンク４の開口部６から水がオーバー７四−するま
で行って液位の安定後マノメータ５の液位を測るもので
おる。この場合タンク４の開口部６の位置が先導管３の
位置なので前述した換算式は不要である。すなわち先導
管３の位置がマノメータ５の液位となる。Further, during measurement, water is supplied from the outlet 10 of the manometer 5 until the water reaches over 74 from the opening 6 of the tank 4, and after the liquid level has stabilized, the liquid level in the manometer 5 is measured. In this case, since the position of the opening 6 of the tank 4 is the position of the leading pipe 3, the above-mentioned conversion formula is not necessary. That is, the position of the leading pipe 3 corresponds to the liquid level of the manometer 5.
このようにすると、管体７の接続部１１で管体７を切断
しても正確に先導管３の位置を知ることができる。In this way, even if the tube body 7 is cut at the connecting portion 11 of the tube body 7, the position of the leading tube 3 can be accurately known.
また、タンク４として第４図および８ｇ５図に示すよう
にタンク本体４ｂの後側面４ａに頂点ｐを下にした三角
形状の開口部６を形成したものを用いることもできる。Alternatively, as shown in FIGS. 4 and 8g5, the tank 4 may have a triangular opening 6 formed in the rear side 4a of the tank body 4b with the apex p facing down.
開口部６の頂点Ｐは先導管３の中心に一致している。The apex P of the opening 6 coincides with the center of the leading tube 3.
この場合先導管３がローリングした時に有利である。In this case, it is advantageous when the leading pipe 3 rolls.
そして、計測時にマノメータ５の出口１０から水を供給
し、タンク４の開口部６から水がオーバーフローするま
で行って液位の安定後マノメータ５の液位を測定すれば
よく、この場合マノメータ５の液位が先導管３の位置（
中心）に一致する。Then, during measurement, water is supplied from the outlet 10 of the manometer 5 until the water overflows from the opening 6 of the tank 4, and after the liquid level has stabilized, the liquid level on the manometer 5 can be measured. The liquid level is at the position of the leading pipe 3 (
center).
このようにすると管体７の接続部（１で管体７を切断し
ても、先導管３がローリングし次ときに４正確に先導管
３の位置を知ることができる。In this way, even if the tube body 7 is cut at the connecting portion (1) of the tube body 7, the leading tube 3 will roll and the position of the leading tube 3 can be accurately determined at the next time.
推進工事は埋設管２を増結していくため管体７も長いま
まのものより順次接続して長くした方が使いやすいので
管体７を切っても正確に計れることは有用である。Since the propulsion work involves adding buried pipes 2, it is easier to use the pipes 7 by connecting them sequentially and making them longer rather than leaving them long, so it is useful to be able to measure accurately even if the pipes 7 are cut.
また、第６図に示すようにタンク４よシオーパーフロー
した水を、タンク４の下に設けたパケット１２で受は排
水ホース＋３ｔ−介して吸引ポンプ１４で吸引し排出す
るようにしてもよい。Alternatively, as shown in FIG. 6, the water that has flowed from the tank 4 may be sucked and discharged by a suction pump 14 via a drainage hose +3t- in a packet 12 provided under the tank 4. .
吸引ポンプ１４は計測時に常時動かしておけば水がこほ
れた時はいち早く立坑１に排水することができる。If the suction pump 14 is kept running at all times during measurement, water can be quickly drained into the shaft 1 when water breaks down.

先導管３内に開口部６を有するタンク４を設けると共に
立坑１にマノメータ５を設け、タンク４を管体を介して
マノメータ５に接続したから、埋設管２か細い場合でも

正確に計測することができる。As described in detail above, the present invention provides a tank 4 having an opening 6 in the leading pipe 3 leading the buried pipe 2, and also provides a manometer 5 in the shaft 1, and connects the tank 4 to the manometer through the pipe body. 5, the vertical position of the leading pipe 3 can be accurately measured even if the buried pipe 2 is thin or curved.

きる。Further, the present invention provides a tank 4t having an opening 6 in the leading 1t3 that guides the buried pipe 2, and also provides a manometer 5 in the shaft 1, and connects the tank 4t to the manometer 5 through the pipe body. An absorption pump 14 is provided in the shaft 1, and the packet is connected to the suction side of the absorption pump 14 via a discharge hose 13. The liquid overflowing from the opening 6 of 4 can always be discharged to the shaft 1 side, so that it can be quickly known that the liquid has overflowed from the opening 6, and the position of the leading pipe 3 can be quickly measured. I can do it.
