この発明は、曲がり管路における横断管の断面計測装置及び該断面計測装置を使用してなされる横断管の断面計測方法に関し、更に詳しくは、流体管路中の対向する立孔間を直線状の横断管を介して流通状態に接続される曲がり管路において、立孔間の横断管内に高さ及び張力の調整された通線が配され、該通線に連結されて使用される横断管の断面計測装置並びに該断面計測装置を使用してなされる横断管の断面計測方法に関する。
本発明は特には、下水道管路における伏越し部の横断管に適用されて好適な当該計測装置及び計測方法に関する。 The present invention relates to a cross-section measuring apparatus for a cross pipe in a bent pipe and a cross-section measuring method for a cross pipe made using the cross-section measuring apparatus. More specifically, the present invention relates to a straight line between opposing vertical holes in a fluid pipe. In a bent pipe line connected in a flowing state via a transverse pipe of the same, a crossing pipe whose height and tension are adjusted is arranged in the transverse pipe between the vertical holes, and is used by being connected to the through line This invention relates to a cross-section measuring apparatus and a cross-section measuring method for a transverse pipe made using the cross-section measuring apparatus.
In particular, the present invention relates to the measurement apparatus and the measurement method that are suitable for being applied to a cross pipe of an overhanging part in a sewer pipe.

下水道管路における伏越し部の人孔、更にはその横断管に溜まる土砂は下水道の流通に障害となり、その除去のため種々の工法が提案されている。
しかし、堆積土砂の除去に先立って、当該横断管内の堆積の状況を把握するための計測が重要であることは論を俟たないが、従来より伏越し部の横断管内の計測に係る技術はその過酷な状況から全く手が付けられておらず、計測、更にはその後の除去・清掃作業の一貫して行われる技術は未だ確立していない。
なお、上記の除去工法の一公知例として特開平１０−１３１２７８のものは、通線ワイヤーに重量性の大型の球状体を取り付け、該球状体を横断管内を逆流移動させて横断管内の堆積物を除去するものであるが、これによれば、通線に大きな荷重負担が掛かり、管口に設置される滑車に負荷を与え、管口の損傷は避けられない。さらには、当該滑車を管口にどのように設置するのか何ら具体的な対策も採られていない。
なお、このような問題・状況は、下水道管路に留まらずその他の管路（上水管、パイプライン）においても起こり得ることである。 The manholes in the overlying part of the sewer pipes and the earth and sand collected in the cross pipes obstruct the circulation of the sewer, and various methods have been proposed for the removal.
However, it is obvious that the measurement for grasping the state of sedimentation in the crossing pipe is important prior to the removal of sediment, but the technology related to the measurement in the crossing pipe in the overpass has been Because of the harsh conditions, nothing has been done, and the technology for consistent measurement, measurement, and subsequent removal and cleaning work has not yet been established.
In addition, as a known example of the above-described removal method, Japanese Patent Application Laid-Open No. 10-131278 discloses a deposit in a transverse pipe by attaching a heavy heavy spherical body to a wire and moving the spherical body in a reverse flow in the transverse pipe. However, according to this, a heavy load load is applied to the line, and a load is applied to the pulley installed in the pipe opening, and damage to the pipe opening cannot be avoided. Furthermore, no specific measures are taken as to how to install the pulley at the pipe opening.
Such a problem / situation can occur not only in the sewer pipe but also in other pipes (water pipes, pipelines).

（作用）
ウインチによる通線への張力の導入において、管口はレール材の管口保護部により保護され、管口の損傷はない。更に、通線は曲がり部に沿って配されるので当該曲がり部において応力集中がなく、張力の均等な伝達がなされる。
レール材の管口保護部を管口に臨んで配されることにより、通線は横断管内において高さの調整された配置を採ることになる。
本断面計測方法において、流速計測装置部は上流側に向けられる。
横断管内の通線は、本断面計測装置の移動する位置において当該計測装置の集中荷重を受けて所期のたわみ及び傾斜角をなす。すなわち、本断面計測装置はその自重を取付け板を介して通線に作用するが、当該装置の自重及び通線の自重により（浮力も付加される）、所期の張力が導入された通線は当該位置で所期のたわみ量及び傾斜角を現す。
通線の上流から下流への移動に伴い、本流速計測装置部内の速度センサーにより横断管内の各位置の実流速を検知し、通線の傾斜角情報により補正を加えて横断管内の各位置の水平流速を得る。
この水平流速情報に基づいて、通線の移動とともに横断管の各断面の断面状況を表示する。 (Function)
In the introduction of the tension to the communication line by the winch, the tube port is protected by the tube port protecting part of the rail material, and the tube port is not damaged. Furthermore, since the through line is arranged along the bent portion, there is no stress concentration in the bent portion, and the tension is evenly transmitted.
By arranging the pipe port protecting portion of the rail material so as to face the pipe port, the through line takes an arrangement in which the height is adjusted in the transverse pipe.
In this cross-section measuring method, the flow velocity measuring device is directed upstream.
The line in the transverse pipe is subjected to the concentrated load of the measuring device at the position where the cross-section measuring device moves, and forms the desired deflection and inclination angle. In other words, this cross-section measuring device applies its own weight to the line through the mounting plate, but due to its own weight and the line's own weight (buoyancy is also added), the line having the desired tension introduced. Indicates the desired amount of deflection and angle of inclination at that position.
As the line moves from upstream to downstream, the actual flow velocity at each position in the crossing pipe is detected by the speed sensor in the flow velocity measuring device, and the position of each position in the crossing pipe is corrected by correcting the inclination angle information of the line. Obtain the horizontal flow rate.
Based on the horizontal flow velocity information, the cross-sectional state of each cross section of the crossing tube is displayed along with the movement of the line.

本発明の曲がり管路における横断管の断面計測装置及び該断面計測装置を使用してなされる横断管の断面計測方法によれば、横断管内に配される通線が移動とともに所期のたわみ及び傾斜角を採り、これに連動して計測装置の位置決めがなされ、かつ、検出された流速値の移動速度補正及び傾斜補正がなされて正確な流速値を得ることができ、これにより横断管内の各位置の正確な断面状況を得ることができる。   According to the cross-section measurement apparatus for a cross pipe in a bent pipe and the cross-section measurement method for a cross pipe made using the cross-section measurement apparatus according to the present invention, the passage line arranged in the cross pipe moves with the desired deflection and Taking the inclination angle, the measuring device is positioned in conjunction with it, and the movement velocity correction and inclination correction of the detected flow velocity value are performed to obtain an accurate flow velocity value. An accurate cross-sectional situation of the position can be obtained.

A curved pipe line is formed from these. In addition, H is a roadbed on the ground surface, and I is deposits such as earth and sand in the overpass manhole.
Thus, in this overhanging portion, the rail material 5 is set up in the human hole 1 and is guided by the rail material 5 to guide the through wire 6. A work device S is disposed on the ground facing the opening 1a of the human hole 1, and winches 7 (7A is an upstream winch and 7B is a downstream winch) mounted on the work device S are connected to both ends of the line 6. Is wound and unwound to move the wire 6 and a necessary tension is introduced into the wire 6.

以下、通線６の設置を手順に従って説明する。
(1) 通線６の導通
通線６を上流側地上より上流側人孔１Ａ、伏越し横断管路２、下流側人孔１Ｂ、そして下流側地上に導通する。
通線６の伏越し横断管路２内への導通については、本実施形態では従来より使用されている噴射ノズルを用いるが、他の態様を除外しない。当該噴射ノズルは出願人らの特許第２７９１５０２号（特許公報では下水道管用洗浄装置）により公知である。
図２は当該特許公報の一図面を示し、ここに、Ｓは下水道管用洗浄装置（噴射ノズル）、Ｈはこの装置Ｓに接続される高圧ホース、Ｉは圧縮空気ホース、Ｊはリール、高圧ポンプ、圧縮部を含む駆動部である。
(1ａ) 地上において、噴射ノズル、高圧水ポンプ、ホースが準備される。
通線（ワイヤー）６の端部を噴射ノズルに結合し、該噴射ノズルとともに上流側人孔１Ａに落し込み、該噴射ノズルを上流側人孔１Ａの管口に臨ませる。そして、噴射ノズルをそのジェット（噴射流）推進により伏越し横断管２内を下流側に向けて進行させる。
噴射ノズルが下流側人孔１Ｂに到達したとき、下流側人孔１Ｂで噴射ノズルの通線を引き上げる。
(1b)上流側及び下流側地上部で通線６を作業装置Ｓの電動ウインチ７に取り付ける。この状態では通線６は弛んだ状態であるが、ウインチ７の駆動により通線６に必要に応じて速やかに張力が導入される。 Hereinafter, the installation of the line 6 will be described according to the procedure.
(1) Conduction of the communication line 6 The communication line 6 is connected to the upstream human hole 1A, the overpass passage 2, the downstream human hole 1B, and the downstream ground from the upstream ground.
As for the conduction of the line 6 into the overpass passage 2, an injection nozzle that has been conventionally used is used in this embodiment, but other aspects are not excluded. Such an injection nozzle is known from the applicant's patent No. 2791502 (in the patent publication, a sewage pipe cleaning device).
FIG. 2 shows one drawing of the patent publication, wherein S is a cleaning device for a sewer pipe (injection nozzle), H is a high-pressure hose connected to the device S, I is a compressed air hose, J is a reel, and a high-pressure pump. A drive unit including a compression unit.
(1a) An injection nozzle, a high-pressure water pump, and a hose are prepared on the ground.
The end of the wire (wire) 6 is connected to the injection nozzle, dropped together with the injection nozzle into the upstream human hole 1A, and the injection nozzle faces the pipe port of the upstream human hole 1A. Then, the jet nozzle is advanced by the jet (jet flow) propulsion so that the inside of the transverse pipe 2 is advanced toward the downstream side.
When the injection nozzle reaches the downstream side human hole 1B, the line of the injection nozzle is pulled up by the downstream side human hole 1B.
(1b) Attach the line 6 to the electric winch 7 of the work device S on the upstream and downstream ground portions. In this state, the line 6 is in a slack state, but a tension is quickly introduced into the line 6 as needed by driving the winch 7.

(2) レール材５の設置
上流側人孔１Ａ、下流側人孔１Ｂに管口保護器付きレール材５を設置する。該レール材５には管口部位においてレベル調整材１０が適宜付加される。
図３〜図６に該管口保護器付きレール材５の詳細構造を示す。
レール材５は、長尺の鋼（特にはステンレス鋼）製の型材いわゆるＣ型チャンネルよりなり、上位より鉛直部５Ａ、曲がり部５Ｂ、水平部５Ｃの各部位よりなる。
該型材（Ｃ型チャンネル材）の断面構成につき、背面部１２（寸法Ａ）、両側面部１３（寸法Ｂ）、前面部１４（寸法Ｃ）よりなり、前面部１４間に溝１５、更に該チャンネル材の内部に溝空間１６が形成される。本実施形態として、Ａ１２ｃｍ、Ｂ６ｃｍ、Ｃ２ｃｍ、厚さｔ３．２ｍｍを採る。 (2) Installation of the rail material 5 The rail material 5 with a pipe opening protector is installed in the upstream side human hole 1A and the downstream side human hole 1B. A level adjusting material 10 is appropriately added to the rail material 5 at the pipe opening portion.
3 to 6 show the detailed structure of the rail member 5 with a tube opening protector.
The rail material 5 is made of a long steel (particularly stainless steel) mold material, a so-called C-type channel, and is composed of vertical parts 5A, bent parts 5B, and horizontal parts 5C from the top.
The cross section of the mold material (C-type channel material) is composed of a back surface portion 12 (dimension A), both side surface portions 13 (dimension B), and a front surface portion 14 (dimension C). A groove space 16 is formed inside the material. As this embodiment, A12cm, B6cm, C2cm, and thickness t3.2mm are taken.

（鉛直部５Ａ）（図３〜図５参照）
鉛直部５Ａは、長尺をもって本レール材５の上位部位を占め、その長さは人孔深さを目途として決められる。
更に、鉛直部５Ａは、分割体１００をもって構成され、各分割体１００を継ぎ足して長尺とされる。このため、各分割体１００は本体１０１の上下端にフランジ１０２（上フランジ１０２ａ、下フランジ１０２ｂ）が形成され、各フランジに開設された穴に締具１０３のボルト１０４を挿通し、ナット１０５を締め込んで接合される。分割体１００の長さは１ｍを標準とし、人力による扱いが容易とされる。
なお、該鉛直部５Ａの下端は後記する曲がり部５Ｂ及び水平部５Ｃと一体とされる。
本レール材５の定位置で、レール材５の上端すなわち鉛直部５Ａの上端は、地上部に突出し、該地上部で固定把持される。
（曲がり部５Ｂ）（図３、図６参照）
曲がり部５Ｂは、所定の曲率（曲率半径）Ｒをもって鉛直部５Ａに連設される。該Ｒは本レール材５の人孔１の壁面との距離（間隔）を決め、本実施形態では例えばＲは３０ｃｍを採る。
本曲がり部５Ｂにおいて、レール材５の背面部１２の背面の中心線上に四分円形状の平板すなわちＲ（アール）材１８が固設される。１８ａはその水平辺部、１８ｂはその垂直辺部である。該Ｒ材１８は所定の厚みを有し、間隔保持とともに補剛の機能を果す。
なお、曲がり部５Ｂにおいて、その背面部１２に溝空間１６に臨んで複数の円筒状転がり軸受（コロ軸受）を相並べて配する態様を採ることができる。この態様によれば、レール材５内に配される通線６の移動が円滑になされる。
（水平部５Ｃ）（図３、図６参照）
水平部５Ｃは、曲がり部５Ｂに連設され、定位置において管口の頂部に当接する。該水平部５Ｃの長さは本レール材５の人孔開口部１ａからの挿入に支障のない長さで決められ、本実施形態では開口部が６０ｃｍを採るとき１５ｃｍ程度を相当とする。
しかして、レール材５が通線６を介して所要の引上げ力を受けるとき、該水平部５Ｃの管口部位では最大の曲げモーメントを受けるものとなる。このため、当該部位ではＲ材１８が補強を担い、更には図３、図６に示すレベル調整材１０とともに使用されて補剛を高める。
水平部５Ｃの先端は、通線６の移動（特には該通線６に移動体が取り付けられる態様において）の便宜に備えて広口部２０が形成される。該広口部２０はいわゆるラッパ状をなし、２０ａはその側方へ広がる部位（側方拡開部）であり、２０ｂはその上方へ広がる部位（上方拡開部）である。上方拡開部２０ｂはレベル調整材１０を使用するもとで形成されるものであり、レベル調整材１０が使用されない場合には不要である。
上記構成において、「管口保護器」は曲がり部５Ｂ、水平部５Ｃによって構成されるが、これに限定されるものではない。 (Vertical part 5A) (refer FIGS. 3-5)
The vertical portion 5A is long and occupies the upper part of the rail member 5, and its length is determined with the human hole depth as a target.
Furthermore, the vertical portion 5A is configured with the divided bodies 100, and is elongated by adding the divided bodies 100 together. For this reason, each divided body 100 is formed with flanges 102 (upper flange 102a and lower flange 102b) at the upper and lower ends of the main body 101, the bolts 104 of the fasteners 103 are inserted into holes formed in the flanges, and nuts 105 are inserted. Tightened and joined. The length of the divided body 100 is 1 m as a standard, and handling by human power is easy.
The lower end of the vertical portion 5A is integrated with a bent portion 5B and a horizontal portion 5C which will be described later.
At the fixed position of the rail member 5, the upper end of the rail member 5, that is, the upper end of the vertical portion 5A protrudes to the ground portion and is fixedly held by the ground portion.
(Bent portion 5B) (see FIGS. 3 and 6)
The bent portion 5B is connected to the vertical portion 5A with a predetermined curvature (curvature radius) R. The R determines the distance (interval) between the rail member 5 and the wall surface of the human hole 1. In the present embodiment, for example, R takes 30 cm.
In the bent portion 5B, a quadrant-shaped flat plate, that is, an R (R) material 18 is fixed on the center line of the back surface of the back surface portion 12 of the rail material 5. 18a is the horizontal side, and 18b is the vertical side. The R material 18 has a predetermined thickness, and performs a stiffening function while maintaining a gap.
In the bent portion 5B, a mode in which a plurality of cylindrical rolling bearings (roller bearings) are arranged side by side facing the groove space 16 on the back surface portion 12 can be adopted. According to this aspect, the through wire 6 arranged in the rail member 5 is smoothly moved.
(Horizontal part 5C) (see FIGS. 3 and 6)
The horizontal portion 5C is connected to the bent portion 5B and abuts on the top of the pipe opening at a fixed position. The length of the horizontal portion 5C is determined by a length that does not hinder the insertion of the rail member 5 from the manhole opening 1a. In the present embodiment, when the opening takes 60 cm, the length is approximately 15 cm.
Therefore, when the rail member 5 receives a required pulling force via the through-wire 6, the maximum bending moment is received at the pipe opening portion of the horizontal portion 5C. For this reason, R material 18 bears reinforcement in the said part, Furthermore, it uses with the level adjustment material 10 shown in FIG. 3, FIG. 6, and raises stiffening.
At the tip of the horizontal portion 5C, a wide-mouthed portion 20 is formed for the convenience of movement of the line 6 (particularly in a mode in which a moving body is attached to the line 6). The wide-mouthed portion 20 has a so-called trumpet shape, 20a is a portion that spreads to the side (side widened portion), and 20b is a portion that spreads upward (upward spread portion). The upper expanding portion 20b is formed when the level adjusting material 10 is used, and is unnecessary when the level adjusting material 10 is not used.
In the above configuration, the “tube opening protector” includes the bent portion 5B and the horizontal portion 5C, but is not limited thereto.

レベル調整材１０（図３、図６参照）
レベル調整材１０は、上記した曲がり部５Ｂ、水平部５Ｃの上面に当接して配される。１０ａはその上面、１０ｂはその側面、１０ｃはその下面である。該レベル調整材１０のＲ部には溝が成形され、Ｒ材１８を受け入れる。
該レベル調整材１０は、後記するように、多段にして使用され得る。第１段はレール材５における曲がり部５Ｂ、水平部５Ｃの曲げ補強としても機能する。 Level adjustment material 10 (see FIGS. 3 and 6)
The level adjusting material 10 is disposed in contact with the upper surfaces of the bent portion 5B and the horizontal portion 5C. 10a is the upper surface, 10b is the side surface, and 10c is the lower surface. A groove is formed in the R portion of the level adjusting material 10 to receive the R material 18.
The level adjusting material 10 can be used in multiple stages as will be described later. The first stage also functions as a bending reinforcement for the bent portion 5B and the horizontal portion 5C in the rail member 5.

レール材５の人孔１への設置は次のようにしてなされる。
(2a)
レール材５の下端部すなわち鉛直部５Ａの最下端部、曲がり部５Ｂ、水平部５Ｃの一体ものを人孔１の開口部１ａより人孔１内へ挿入し、一旦その上端を地上部で把持し、次いで、その上に鉛直部５Ａの分割体１００をそのフランジ１０２を介して継ぎ足し、再び人孔１内へ挿入する。レール材５の下端には適宜レベル調整材１０が取り付けられている。
以後、レール材５の鉛直部５Ａをその分割体１００により順次継ぎ足し、長尺のレール材５を得る。
レール材５の下端が管口に臨む位置になるとき、水平部５Ｃの上面を管口の頂部より一定の間隔を保持しつつ押し込み、しかる後、レール材５を引き上げ、水平部５Ｃの上面、もしくはレベル調整材１０の上面を管口の頂部に当接させる。(2b)
レール材５の鉛直部５Ａはその下端のＲ材１８により人孔１の内壁と所定の間隔をもって配される。すなわち、本実施形態では人孔１の内壁より３０ｃｍの間隔を保って配されることになる。
地上部においては、レール材５の上端が固定される。 The rail material 5 is installed in the manhole 1 as follows.
(2a)
The lower end of the rail member 5, that is, the lowermost end of the vertical portion 5A, the bent portion 5B, and the horizontal portion 5C are inserted into the human hole 1 through the opening 1a of the human hole 1, and the upper end is once held by the ground portion. Then, the divided body 100 of the vertical portion 5A is added on the flange 102 through the flange 102 and inserted into the human hole 1 again. A level adjusting material 10 is appropriately attached to the lower end of the rail material 5.
Thereafter, the vertical portion 5A of the rail material 5 is sequentially added by the divided body 100, and the long rail material 5 is obtained.
When the lower end of the rail member 5 is at a position facing the pipe opening, the upper surface of the horizontal part 5C is pushed in from the top part of the pipe opening while keeping a certain distance, and then the rail member 5 is pulled up, the upper surface of the horizontal part 5C, Alternatively, the upper surface of the level adjusting material 10 is brought into contact with the top of the pipe opening. (2b)
The vertical portion 5A of the rail member 5 is arranged with a predetermined distance from the inner wall of the human hole 1 by the R member 18 at the lower end thereof. That is, in this embodiment, it is arranged with an interval of 30 cm from the inner wall of the human hole 1.
In the above-ground part, the upper end of the rail material 5 is fixed.

ここに、通線６は鋼線（ワイヤー）が使用され、径φ１２ｍｍを規格とし、単位長さ質量ｗ０．５３ｋｇ／ｍを採る。また、ウインチ７は上下流側とも１．３トンを規格として使用される。 (3) Placement of the wire The upstream winch 7A and the downstream winch 7B of the work device S are driven, and the loose wire 6 is inserted into the groove of the vertical portion 5A and the bent portion 5B of the rail member 5 with the tube protector. 15 is guided into the groove space 16 and is wound around the downstream winch 7B along the groove space 16. As a result, the connecting line 6 is consistently stretched in a predetermined state from the upstream side to the downstream side in the curved pipeline.
Here, a steel wire (wire) is used as the through wire 6, the diameter φ12 mm is standard, and the unit length mass w 0.53 kg / m is adopted. The winch 7 is used with 1.3 tons as the standard on both the upstream and downstream sides.

Alternatively, the flow rate is obtained by an open channel flow rate measuring device temporarily installed in the sewer pipes 3A and 3B.
As an example of such a flow rate measuring device Q, a swash plate having a notch (triangle, quadrangle) is installed at the mouth of the sewer line 3B facing the downstream side human hole 1B, and the flow from the notch A crest-type measuring method is adopted in which the water level is measured upstream of the dam plate while maintaining the flow rate q.

The sensor 43 according to the present embodiment has a uniaxial function and does not have a tilt angle correction function.
The communication line 44 is covered with a waterproof layer and opposes the sandwiching action of the frame body 42.
The horizontal blade 47 and the weight 48 are added for the stability of the measuring device V in water, and are omitted when stability is obtained, and are non-essential matters.

Information such as the inner diameter and length of the transverse tube 2 is input from the input means 50a. The correction calculation unit 50d corrects the inclination angle of the actual flow velocity data from the electromagnetic flow velocity sensor 43. Further, the traveling speed of the measuring device V is corrected to the detection speed (actual flow speed). On the monitor 51, the image-processed information is displayed.

Since the speed sensor 43 moves with the inclination of the line 6, the measurement speed (actual flow velocity) reflects the movement speed and the inclination angle of the line 6. As described above, this actual flow velocity is corrected and displayed as an actual horizontal velocity by correcting the relative velocity and the inclination angle by the correction calculation unit 50d in the processing device 50.
Note that the movement of the line 6 is not limited to being performed at a constant speed but adopting intermittent movement including stop (detection of the flow velocity at the time of stop).
(Cross-section inhibition rate)
The movement of the measuring device V is associated with the flow rate measurement result (flow rate q) in the step (5a).
That is, by dividing the flow rate q by the horizontal velocity v, the cross-sectional area A of the transverse pipe 2 at the position is calculated.
This cross-sectional area A is smaller than the cross-sectional area A ′ of the transverse pipe 2 at the time of new construction,
