2. Description of the Related Art FIG. 1 is an explanatory diagram of a manhole. At the bottom of the manhole, a groove called an invert is formed by further drilling the bottom, and this groove connects the flow of the sewer pipe that enters and exits the manhole.
A conventional repair device that intrudes into a buried pipe such as a sewer pipe and repairs it by remote control is inevitably a long device due to the fact that it is inserted into the pipe. The device itself (structure frame) was rigid in the longitudinal direction.
Therefore, as can be understood from FIG. 1, the length of the device cannot exceed the bottom diameter of the manhole even at the maximum. But,
It can only be used in the lucky case that the groove in the hole is straight. Because the manhole is arranged at the bending point of the flow path and the confluence branch point,
As shown, the grooves are often Y-shaped or bent.

The repair work is carried out by inserting the device into the sewer pipe from this hole. However, since the device is pushed into the groove after inserting it into the pipe, the bent groove that cannot be dropped is for repair work. Therefore, it was once destroyed and after the completion of the work it was necessary to restore and shape the concrete again. Under such circumstances, the total length of the conventional rigid structure device cannot exceed 50 cm. However, cracks in the sewer pipe are likely to occur in the longitudinal direction of the pipe, and if there is such a long repair point, the length of the device was short, and the device had to be repeatedly put in and taken out of the pipe for repeated work. . Further, if there is a bent portion in the middle of the sewer pipe, the conventional device cannot pass through the corner, so that some parts cannot be repaired. In such a case, there was no choice but to carry out excavation work. The present invention aims to solve such a problem.

Inside the main body 10, not only the airtight internal space 14 constituting the air control means as described above is formed, but also the following heating means 15 is built in. That is, a heater as a heating means is provided along the inner wall of the tubular body 11. In the embodiment, a rod-shaped flexible member in which a heater is embedded is used, but as the heating means 15, any known means may be used as long as the flexibility of the main body 10 is not impaired. . By this heating means, the inner wall of the buried pipe 1 was crimped by expansion pressure.
The repair material is cured by heating. In this way, the main body 10 of the embodiment has a flexible structure that is flexible.

[0011] waist 11 of thus constituted flexible freely body 10, deposited as appropriate repair material, further on this, cover the repair material with a protective sheet with a string. And girth 1
1 is a state in which the waist diameter 11 is reduced by degassing the internal space 14. Then, the main body 10 is inserted into the buried pipe 1 while keeping the end of the cord at hand. At the repaired part, pull the protective sheet away from the waistline by pulling the cord around and pull it out of the buried pipe. Thereafter, the waist is expanded by injecting air by the air control means 14, the repair material is pressure-bonded to the inner wall of the buried pipe, and the heating means 1 is left as it is.
5, the repair material is heated and hardened. After the repair material hardens, the expansion of the waistline 11 is released to return to the normal form, or
Alternatively, if necessary to pass the middle of the bending portion back again, in a state of being contracted barrel, it recovered from the buried pipe.

In order to reduce the size of the waistline 11 in advance, it is preferable to provide the waistline member, that is, the tubular body 11 with a recess 20 as shown in FIG. FIG. 6 shows a vertical cross section and a horizontal cross section when the waist circumference is normal. In the illustrated example, the thickness of the body on the center side is reduced and the thickness of both ends is increased. As a result, as shown in FIGS. 7 to 9, ideally, the process of contraction and expansion of the waist, that is, the tubular body 11, and the completion of expansion can be performed. FIG. 7 shows a longitudinal section and a transverse section when contracted. Due to the concave habit 20 at the center of the trunk, it quickly starts to dent from the center. In addition, for example, if vertical depressions are formed so as to cause appropriate vertical stripes, contraction can be induced in the cross-sectional shape shown in the drawing.

FIG. 8 shows a vertical section and a horizontal section immediately after the start of expansion. The center with a dent is thin and is weak against air pressure. Therefore, only the center of the body length starts to bulge and the bulge gradually spreads to both ends. This is the optimum crimping method for crimping the repair material to the inner wall of the buried pipe. Kashi,
This is because the water adhered to the inner wall is pushed by the bulging wave from the center of the crimping region toward the end, so that the defective crimping due to the water remaining in the crimping region can be eliminated. The waist is expanded and the repair material is pressure-bonded to the inner wall of the buried pipe to heat and cure the repair material, the expansion around the waist is released, and the repair is recovered from the buried pipe.

The repair material is a sheet-shaped repair member around the waist.
It may be as a tubular wound to 11. In this case, the ends are optimally overlapped with each other, but the overlaps are not always necessary, and the gaps between the ends may be opened depending on repair conditions. Further, FIG. 10 shows a means for protecting the repair material which is replaced with a string-attached protection sheet, and surrounds the outer shell of the tubular body 10 to which the repair material is applied in a tubular shape with a further interval, and extends in the longitudinal direction of the tube. A shutter 30 that opens and closes is provided.
Further, in the above-mentioned embodiment, the sewer pipe is taken as an example of the buried pipe, but not only the sewer main pipe and the sewer pipe, the object to which the present invention can be applied is not limited to the buried pipe, especially for existing pipes, especially small diameter pipes. Widely applicable for repairing tortuous pipes.

According to the present invention, the body of the flexible body, to which the repair material is applied and is inserted into the buried pipe, is placed inside the buried pipe in a state in which the waist diameter is reduced by degassing the internal space. Since it is inserted, even from a manhole with a small insertion work space or a small masu, it can be sent to the buried pipe while bending the device. Further, even if the buried pipe has a bent portion, the main body passes while bending. Moreover, since the body is reduced, damage to the repair material due to contact with the inner wall of the buried pipe and foreign matter adhering to the inside of the pipe is reduced.
It Further, according to the apparatus of claim 2 , since the central axis forming the skeleton of the main body is the coil spring, the diameter of the apparatus can be greatly reduced and the weight thereof can be reduced in cooperation with the flexible waist member that can be expanded and contracted. Not only is this possible, but the length of the device body can be increased to several meters. Furthermore, according to the present invention, since the device can be formed to be long, it is not necessary to repeat the work many times as in the conventional device when the repair area is long, and if the device is long, the repair can be completed in one operation. It has a remarkable effect that it can be done.
