Description

The present invention relates to a cleaning device for a transverse pipe in a curved pipe and a method for cleaning the transverse pipe using the cleaning device, and more particularly, a straight transverse pipe between opposing vertical holes in a fluid pipe. In a bent pipe line connected to a circulation state via a through-line, a cross-line having a height and tension adjusted is arranged in a cross-line between the vertical holes, and the cross-line pipe cleaning device used by being connected to the line In addition, the present invention relates to a method for cleaning a cross pipe made using the cleaning device.
In particular, the present invention relates to the cleaning device and the cleaning method which are suitable for being applied to a cross pipe of an overhanging part in a sewer pipe. The “straight transverse pipe” is not limited to the horizontal, but includes an inclined pipe.

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 a technology that consistently performs measurement, removal, and cleaning work has not yet been established.
In addition, as a known example of the above-described removal method, Japanese Patent Laid-Open No. 10-131278 discloses a method in which a large spherical body is attached to a wire, and the spherical body is moved backward in the transverse pipe to remove deposits 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 problems / situations are not limited to sewer pipes, but are the same in other pipes (water pipes, pipelines).

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of a cross pipe cleaning device and a cross pipe cleaning method using the cleaning device according to the present invention will be described with reference to the drawings.
FIGS. 1-17 shows the application to the overhanging part of the sewer pipe which is one Embodiment of this invention.

FIG. 1 shows an overhanging part of a general sewer line. In the figure, 1 is a human hole (1A is an upstream human hole, 1B is a downstream human hole), 2 is a transverse pipe line between the human holes 1A and 1B (an overpass pipe line), 3A is an upstream pipe line, 3B Indicates a downstream pipe line. A curved pipe line is constituted by the upstream side pipe line 3A, the upstream side human hole 1A, the transverse pipe 2, the downstream side human hole 1B, and the downstream side pipe line 3B. 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 deposits (deposits) at the bottoms of the upstream and downstream human holes 1A and 1B are preliminarily removed. About the wrinkle of the deposit | attachment in the bottom part of this human hole 1A, 1B, although the dredging apparatus conventionally used is used in this embodiment, another aspect is not excluded. Such dredging devices are known from Applicants' patent 1868794, patent 2097712, patent 3706449, and patent 3847969.
The dredging operation is not an essential matter in the present invention.

  Thereafter, the rail material 5 is stood in the manhole 1 at the overhanging portion, and the through wire 6 is guided by being guided by the rail material 5. 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.

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 (FIG. 5) 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 drive unit including a reel, a high-pressure pump, and 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) Installation of rail material 5 (see Figs. 3 to 6)
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. In the figure (FIG. 3), L1 is the vertical length of the vertical portion 5A, L2 is the vertical length of the bent portion 5B, L3 is the horizontal length of the horizontal portion 5C, and the total height L of the rail member 5 is L1 + L2. .
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.

(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.
Thus, when the rail member 5 receives the required pulling force, the pipe portion of the horizontal portion 5C receives the maximum bending moment. 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.

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.

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.

A desired concentrated load acts on this line, and a desired curve state (deflection, inclination) by superposition is taken. Thereby, the line system in this invention is constructed | assembled. This suspension curve state is represented by a strict suspension curve (catenary curve) solution or, usually, a parabolic solution.
That is, the main line 6 is provided for movement of the equipment in the transverse pipe 2 after being arranged in the transverse pipe 2, and when the equipment, that is, the moving body is subjected to water resistance, it is broken or greatly bent.

When the main line 6 is subjected to the desired tension, the deflection at the center of the transverse pipe 2 (20 m) of the line 6 is 2.7 cm, and the load of the moving body fixed to the line 6 is 18. When taking 0 kg, the deflection at the center of the line 6 is 11.7 cm, and this does not hinder the work in the transverse pipe 2 (standard diameter 60 cm) attached to the line 6. Further, the bending moment due to the desired tension at the pipe opening is countered by the resistance moment of the cross section of the rail material 5.

In this embodiment, the basic position is three rotations of the central axis of the measuring device A and the length measuring wing 43. The intersection point with the plane formed by the spindle 54 is selected.
(Control board 46)
The control board 46 is also disposed at a fixed position in the sealed space J at the rear of the rear frame 52, and performs transmission and reception of signals and device control within the apparatus main body 40. That is, the signals from the angle sensor 44 and the posture sensor 45 are received and sent to the outside, and the instruction signal is sent to the electromagnetic valve 59 of the fastening mechanism 57 described above in response to the signal from the outside. The signal from the attitude sensor 45 is corrected to an attitude signal at a zero point.
(Communication code 47)

(6b) Measuring device A for the downstream pipe port
When the measuring device A reaches the downstream port of the crossing tube 2, the operation of the monitor is finished, and the mounting carriage 32 of the communication line 6 faces the wide opening 20 at the end of the rail member 5, so that the rail member 5 is smooth.

(7) Second measurement Following the step (6c), the measuring device A is rotated 180 ° around its central axis, and the mounting plate 38 ′ is connected to the mounting plate 35 of the wire 6. Thereby, this measuring apparatus A takes Y arrangement for the radiation angle of the length measuring wing 43. Therefore, the radiation angle of the length measurement wing 43 is set at 60 ° intervals by the first reverse Y arrangement and the Y arrangement.
The measuring device A is subjected to measurement work according to the steps (5a), (5b), (5c), (6a), (6b), and (6c).
In this measurement, the cross-sectional state of the transverse tube 2 is measured at 60 ° intervals from the top of the tube. Note that the second measurement can be omitted as appropriate.
(8) Completion of measurement work The measurement work is completed by the above steps (5) to (7).

During the above measurement work, at least during the movement of the measuring device A in the crossing tube 2, the measuring device A is automatically operated according to a predetermined program.
The measuring method by the measuring apparatus A is an example of measuring work, and other measuring methods (for example, measurement by an ultrasonic meter or cross-sectional measurement by an velocimeter) can be freely adopted. It can be omitted.
And the cross-sectional condition (deposition condition) in the cross pipe 2 by this measurement work is utilized as preliminary data for the following cleaning work.

(9) Installation and operation of cleaning device B (see FIGS. 13 and 14)
After the above-described measuring operation of the sediment accumulation state in the cross pipe 2 by the measuring device A, the cleaning operation by the cleaning device B is performed. In the main cleaning work, the data of the measurement work described above (the state of the sediment) is used.
Hereinafter, an installation procedure in which the cleaning device B is a mud scraping device will be described.
The cleaning device B is attached via the above-described attachment carriage 32 interposed in the line 6.
16 and 17 show the detailed configuration of the cleaning device B. FIG. In the figure, the traveling direction is the front (front).
The cleaning device B (left and right front and rear, top and bottom are in the drawing) is a wide box-like frame body 70, a mounting plate 71 projecting from the center of the upper surface of the frame body 70, and the front and rear of the frame body 71. And a scraping plate 72 fixed to each.
The frame body 70 is long in the tube axis direction (longitudinal direction), and the lateral width is ensured to a width that does not collide with the tube port at the tube port (approximately 20 cm as a guide). That is, the width is a width that allows the frame body 70 to enter the pipe opening as much as possible in a mode in which the rail member 5 is arranged directly on the top of the pipe opening (that is, in a state where the level adjusting member 10 is not provided).
The mounting plate 71 is provided with mounting holes 71a for joining the mounting carriage 32 side by side. The mounting hole 32a of the mounting carriage 32 and the mounting hole 71a of the main mounting plate 71 are aligned with each other, and the fasteners (bolts and nuts) 39 are attached to the mounting holes 32a.
The scraper plate 72 includes a front scraper plate 72A and a rear scraper plate 72B, and is fixed to the front and rear plates of the frame body 70 with fasteners (bolts and nuts) 74. The width of the scraping plate 72 is substantially equal to the width of the frame body 70, the vertical cross-sectional shape is bent at the upper portion, and is inclined downward at a constant inclination angle (30 ° in this embodiment). The lower end of the scraping plate 72 has an arc shape, but may be linear. The scraping plate 72 is appropriately replaced by the fastener 74.
Furthermore, in this embodiment, the front scraping plate 72A and the rear scraping plate 72B are different in height, and the height of the rear scraping plate 72B is longer than the front scraping plate 72A by Δh. This increases the scraping efficiency. However, both scrapers 72A and 72B may have the same height.
Furthermore, the width of the scraping plate 72 may be appropriately widened at the lower portion as indicated by a two-dot chain line in the figure.

(9a) Mounting, descending / sinking, and placement in the pipe opening of the cleaning apparatus B Regarding the mounting, descending / sinking, and placement in the pipe opening of the cleaning apparatus B, the mounting, descending / sinking, and pipe opening of the measuring device A described above Follow the procedure described in (5a) (5b) (5c).
In addition, about the initial arrangement | positioning to the pipe opening of this cleaning apparatus B, it is supposed that there is no level adjustment material 10 to the rail material 5, and the cleaning apparatus B will be in the state nearest to a vertex in a pipe opening part. At this time, the wide frame body 70 of the cleaning device B is also as close to the tube wall as possible.

(9b) Work of the cleaning device B The upstream side winch 7A and the downstream side winch 7B advance the cleaning device B from the upstream side through the cross pipe 2 with a predetermined tension via the communication line 6, and the downstream side To move.
The cleaning device B is initially located at the upper part of the upstream side pipe opening, and gradually falls downward due to the slack of the communication line 6 as the cleaning device B proceeds, and reaches the lowest point in the center. After that, it gradually rises again and reaches the highest position at the downstream side port. Therefore, the scraping action of the deposit on the scraping plate 71 is performed from the middle of the transverse pipe 2.
When the forward operation of the first step is completed, the cleaning device B is moved backward and pulled back to the starting point of the transverse tube 2.
As a second step, the rail material 5 is slightly lowered to lower the height of the through wire 6 in the transverse pipe 2. After that, the cleaning device B is advanced from the upstream pipe port to the downstream pipe port with a predetermined tension by the upstream winch 7A and the downstream winch 7B again through the wire 6, and is moved to the downstream pipe port. The scraping plate 71 of the cleaning device B is located at a lower position than the first step, and scrapes off the next deposit.
Thereafter, the above steps are repeated, and the scraped soil is dropped into the bottom of the downstream side human hole 1B to remove deposits in the transverse pipe 2 and complete the scraping operation.
When the diameter of the cross pipe 2 is large (for example, exceeding 1 m), the rail material 5 is pulled up, the level adjusting material 10 having a height exceeding the R material 8 is attached to the rail material 5, and the rail material 5 is again attached to the person. It sinks in the hole 1, the horizontal part 5C faces the inside of the pipe opening, and the rail member 5 is installed in a fixed state. Thereby, the communication line 6 is installed at a predetermined height.
In the above-described installation operation and movement operation of the cleaning device B, the data on the deposition state obtained from the above-described measurement work is used.

  In the above-described progress of the cleaning device B in the transverse tube 2, the lower end of the cleaning device B draws a locus that protrudes downward, but the wire 6 is loosened at the tube port and the lower end of the scraping plate 71 is moved downward. The cleaning device B is gradually lifted with the progress of the cleaning device B, the maximum tension is applied at the center, and then the wire 6 is loosened again to lower the lower end of the scraping plate 71 downward. The lower end of the catch plate 71 can be moved horizontally.

  The above-described operation of the cleaning device B is based on a continuous (non-divided) operation from the upstream side pipe port to the downstream side pipe port, but the downstream side (for example, the downstream side 1 / 4), when the sediment in the downstream cross pipe 2 is removed, the cleaning device B is gradually moved to the upstream side to perform a cleaning operation, and a division operation is performed to remove all accumulated sediment. be able to. In this case, it goes without saying that the data of the measurement work described above is used for the accumulation state in the transverse pipe 2.

(10) Reworking of measuring device A Thereafter, the deposition state in the transverse pipe 2 is remeasured as necessary, and further the scraping work of the deposit is performed.
That is, the cleaning device B is switched to the measuring device A again, and the state of the inner surface of the crossing tube 2 is reconfirmed on the monitor. If the deposit removal status is not sufficient, the cleaning device B is used to scrape the deposit.
In addition, the process of this (10) is arbitrary operations.

(11) Completion of work The series of work of measurement and cleaning is completed with the above steps (1) to (10), but in the case of only cleaning work, the steps (1) to (4) and (9) are performed. Become.
Thereafter, the rail material 5 in the manhole 1 is removed, and the earth and sand accumulated in the bottom of the downstream manhole 1B in the step (9) is dredged as described above, and the operation is completed.
