[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is for repairing cracks or breakages that have occurred at the mouth of a main pipe connected to a human hole (manhole). The present invention relates to a repairing machine integrated with a human hole and a mouth used for attaching the repairing material.

[0002]

SUMMARY OF THE INVENTION According to the present invention, in order to repair cracks or breakages occurring in the main mouth of a main pipe connected to a human hole, the main pipe mouth has a cylindrical shape with a flange. An object of the present invention is to provide a human-hole / integral-type repair machine capable of heating and pressing the cylindrical portion and the flange portion of the repair material at the same time to adhere the repair material when the repair material is attached.

[0003]

In order to achieve the above-mentioned object, a repairing machine integrated with a manhole inlet according to the present invention has a flanged cylindrical repair material around the mouthpiece connected to the inside of the human hole. In the repair machine with integrated human mouth and tube that was pressed and heated,
It has an arch-shaped main plate that straddles the peripheral portion of the pipe mouth, and left and right leg plates that are fixed to each of the two legs of the main plate so that the height of the legs can be adjusted. According to the configuration, a tube mouth repairing machine is constructed in which elastic rubber that is continuously inflatable along the tube mouth contacting side of the main plate and the lower sides of the left and right leg plates is fixedly mounted on the main plate. Further, a bullet sleeve having a built-in heater and having a flexible sleeve that expands into a cylindrical shape along the inner peripheral surface of the pipe mouth by air introduction is coupled along the inner periphery of the main plate of the pipe mouth repair machine. It is characterized by being done.

2. Description of the Related Art Conventionally, main pipes such as sewers buried in the ground include ceramic pipes, fume pipes made of concrete, plastic pipes made of synthetic resin, etc., but cracks, damages, etc. occurred due to deterioration. In this case, a stretchable cylindrical repair material made by laminating a glass cloth and a woven cloth is attached to the inner peripheral surface of the main pipe around such a failure portion.

In particular, as shown in FIG. 8, the main pipe 2 connected to the manhole 1 is likely to be cracked at the pipe mouth 3. In order to repair such a pipe opening 3, a cylindrical repair material 5 with a flange as shown in FIG. 6 is used.

When the inverts 8 and 8 are provided on both sides of the human hole 1, the cylindrical repair material 5 has the inverts 8 and 8 respectively.
The repair material 5 can be attached also to the upper surface of the and the groove-shaped peripheral surface 8a between the inverts 8 on both sides, and a semi-cylindrical portion 6a is provided on the opposite side from the cylindrical portion 6 of the repair material 5. The rest is an arch-shaped flange portion 7, and the flat portion 7 is provided at a portion connecting both ends of the flange portion 7 to both ends of the semi-cylindrical portion 6a.
a and 7a are provided.

According to such a repair material 5, the cylindrical portion 6 is attached to the inner circumference of the main pipe 2, the flange portion 7 is attached along the wall surface of the outer circumference of the pipe mouth 3, and both side inverts 8,
The semi-cylindrical portion 6a is attached to the groove-shaped peripheral surface 8a between the eight, and the flat portions 7a and 7a are further attached to the upper surfaces of the inverts 8 and 8 on both sides.

By the way, in order to attach such a repair material 5, a thermosetting adhesive containing a thermosetting agent in an FRP agent is applied to the entire outer surface of the repair material 5 and heated while pressing. It is necessary to bond the thermosetting adhesive while promoting the curing of the adhesive.

However, as a device for heating the above-mentioned repair material while pressing it, what has been conventionally called a bullet sleeve has been developed. This bullet sleeve accommodates a rubber sleeve that expands in a cylindrical shape in the main tube and introduces air into the rubber sleeve to expand the bullet sleeve, thereby pressing the repair material 5 against the inner surface of the main tube, and The repair material 5 is heated by a heater provided inside the sleeve.

However, this bullet sleeve has a problem in that the flange portion 7 and the flat surfaces 7a, 7a cannot be heated and pressed even though the cylindrical portion 6 of the repair material 5 can be heated and pressed.
