Description

  The present invention relates to a container apparatus for housing a rehabilitation pipe for rehabilitating an existing buried pipe such as a sewer pipe, a water pipe, an agricultural water pipe, a gas pipe, etc., and transporting it by a truck such as a truck. It is related with the container apparatus suitable for accommodating and conveying in the state wound around the drum.

In recent years, countermeasures against aging of buried pipes such as existing sewer pipes, water pipes, agricultural water pipes and gas pipes have been demanded. As an example, a rehabilitation method is known in which a rehabilitation pipe made of a thermoplastic resin is lined on the inner wall of a buried pipe (see, for example, Patent Documents 1 and 2). This seed rehabilitation tube is originally a circular cross section, but is reduced in diameter or flattened in a manufacturing process by recessing one side in the circumferential direction. It is wound around the drum in this deformed state. Hereinafter, the rehabilitation pipe wound around the drum is referred to as a “rehabilitation pipe winding body”.
The rehabilitation pipe winding body is loaded on the loading platform of a truck such as a truck and transported to the rehabilitation construction site. Put the resin cover on the rehabilitation pipe wrapping body during transportation.
At the rehabilitation construction site, the rehabilitation pipes are sequentially fed from the drum and inserted into the buried pipes via the starting manhole. And pull the rehabilitation pipe with a winch from the reaching manhole side.
Thereafter, the rehabilitation pipe is heated to a certain temperature (for example, about 70 ° C. or more) with high-temperature steam or the like. Then, the rehabilitation pipe returns to the circular cross section. This property is called shape recovery. The temperature is referred to as a shape recovery temperature. By putting compressed air into the rehabilitating pipe that has returned to the circular cross section, the rehabilitating pipe expands, and the rehabilitating pipe can be brought into close contact with the inner wall of the buried pipe.

From the viewpoint of protecting the rehabilitated pipe during transportation and preheating, it is preferable to install a container on the loading platform of a truck such as a truck and accommodate and transport the rehabilitated tube winding body in the container. A typical container for a cargo truck has a box shape that can be sealed, and is provided with a door at the rear end. Open this door and lift the cargo with a forklift. It is not designed to be hung with a crane.
However, there is not always a forklift at the construction site. Moreover, it does not necessarily have a crane vehicle. On the other hand, if a freight car with a crane such as UNIC is used as a freight car, the rehabilitation pipe winding body can be lifted without a dedicated crane car. Therefore, the container for transporting the rehabilitated tube winding body must be a structure that can be lifted and unloaded, or a structure that can be lifted and unloaded, rather than a container that can only be lifted and unloaded. Is desirable.
As such a container structure, for example, it is conceivable that the top plate of the container can be opened, the rehabilitation pipe winding body is taken in and out from above the container with the top plate removed, and then the top plate is attached. It is also conceivable that the bottom plate of the container is eliminated and the container is covered from above after the rehabilitation pipe winding body is loaded on the loading platform.

  However, in general, the diameter of the drum for the rehabilitation pipe is about 2.6 m, and when this is added to the height of the gantry and the truck bed, it becomes about 4 m. To load and unload a rehabilitation pipe winding body on a container with the top plate opened using a crane or to cover a bottomless container on a rehabilitation pipe winding body, a height of about 8 m is required. . Not applicable in places where the workable height is restricted below the required height, such as when there are obstacles such as overhead wires below the height, or the boom length of the crane is less than the required height. . Further, when lifting the rehabilitated tube winding body or the bottomless container, it is necessary to take care not to hit or catch the rehabilitated tube winding body and the container. Furthermore, after hanging a container top plate or a bottomless container, it is necessary to fix it firmly, which increases safety management items.

  In view of such circumstances, an object of the present invention is to provide a container device that can lift and retract a rehabilitation pipe wound body, or can lift and unload a rehabilitation tube wound body, and is less likely to be caught in a height limit even when lifted. To do.

In order to solve the above problems, the present invention is a container device for transporting a rehabilitation pipe lined on the inner wall of an existing buried pipe by a truck.
A rail provided on the loading platform of the truck to extend in the vehicle length direction;
A container displaceable between a retracted position and a storage position along the rail;
A drum mount provided in a portion corresponding to the accommodation position of the loading platform;
The rehabilitation pipe winding body formed by winding the rehabilitation pipe around the drum can be mounted on the drum mount and can be accommodated in the container when in the accommodation position.

According to the container device, the drum pedestal on the part corresponding to the storage position of the loading platform is opened by setting the container to the retracted position. In this state, the rehabilitation pipe winding body is loaded and unloaded onto the accommodation position corresponding portion of the loading platform. At this time, the rehabilitation pipe winding body may be lifted by a crane or the like, or may be lifted by a forklift or the like. In short, the rehabilitation tube winding body can be lifted and removed, or can be lifted or lowered and lifted or unloaded.
Moreover, the rehabilitation pipe winding body may be lifted or lifted at least higher than the rail or the drum mount. There is no need to lift it higher than the top of the container. Therefore, even if there is a height restriction, it is difficult to catch this.
Moreover, it can avoid that the rehabilitation pipe winding body in loading / unloading collides with a container, or is caught, and can work easily and safely. After the rehabilitation tube winding body is mounted on the drum mount, the container is placed in the accommodation position. At this time, the door that faces the container accommodation position is left open. Thereby, the rehabilitation pipe winding body is accommodated in the container. In this way, the rehabilitation tube winding body can be easily put in and out of the container.

The container-shaped container main body having side walls and top plates on both sides in the vehicle width direction, and a side portion facing the accommodation position when at least the retreat position of both side portions in the vehicle length direction of the container main body It is preferable to include a double door with a double door.
By displacing the container from the retracted position to the storage position with the door open, the drum mount and thus the rehabilitation pipe winding body can be stored in the container body. By opening the door of the container with a double door, the door can be opened and closed reliably even at a site where the height is limited or a site where the width is narrow.

It is preferable that the container in the retracted position is disposed on a first side portion in the vehicle length direction of the loading platform, and the container in the storage position is disposed on a second side portion in the vehicle length direction of the loading platform.
As a result, the container can be moved back and forth between the retracted position and the storage position on the loading platform of one truck.
The rail includes a first rail portion disposed on the first side portion and a second rail portion disposed on the second side portion, and the first rail portion and the second rail portion are connected in a straight line. In addition, it is preferable that they can be separated from each other.
Thereby, the installation and removal to a cargo bed can be performed for every rail part. For example, the container and the first rail portion can be integrally installed or removed after the container is engaged with the first rail portion. In addition, in a state where the drum mount and the second rail portion are joined, the drum mount and the second rail portion can be integrally installed or removed. As a result, the container device can be efficiently installed and removed from the truck.

It is preferable that a window is formed on the side wall of the container.
By opening the window, you can check the fixed state of the rehabilitation tube winding body. Furthermore, the fixing operation and the fixing releasing operation of the rehabilitation tube winding body can be performed through the window. It is also possible to hang a binding cable body such as a sling between the rehabilitation pipe winding body and the hook on the side of the lorry through the window.

It is preferable to further include a heating system for heating the rehabilitated tube winding body in the container.
During transportation of the rehabilitated tube winding body with a truck, the rehabilitated tube can be heated to be in a soft state. Thereby, after arriving at the construction site, the rehabilitated pipe can be immediately delivered from the rehabilitated-winding body. The heat softening process of the rehabilitated pipe at the construction site can be omitted, and the construction period can be shortened.

It is preferable that the heating system includes a hot air generator that heats and blows air, and a blowout nozzle that is connected to the hot air generator via a blow duct and faces the inside of the container.
As a result, hot air can be blown into the container from the blowing nozzle to heat the rehabilitation pipe.
It is preferable that the hot air generator is disposed on the first side portion.
Thereby, the space of the 1st side part of a loading platform can be utilized as an installation place of a hot air generator. Furthermore, a power source (such as a generator) of a hot air generator can be installed on the first side of the loading platform.

  According to the container according to the present invention, the rehabilitation tube winding body can be lifted and unloaded, or can be lifted or unloaded. Furthermore, when lifting, even if there is a height restriction, it is difficult to catch it. Therefore, safety (collision avoidance) can be ensured, the quality of the rehabilitation pipe can be maintained, and workability can be improved.

The container apparatus 2 is constructed in advance on the loading platform 11 of the truck 10. The components 20 to 60 of the container device 2 are mounted on the loading platform 11 by being lifted or lifted by a crane or a forklift. The components 20 to 60 and the members obtained by further disassembling them may be placed on the cargo bed 11 by lifting or lifting, and then assembled on the cargo bed 11. Alternatively, a plurality of components may be assembled and placed on the loading platform 11. For example, after placing the container 20 on the front support base 33, the container 20 and the front support base 33 may be installed on the front side 11a of the cargo bed 11 by lifting and lifting them together. Alternatively, after the drum base 40 is joined to the rear support base 34, the drum base 40 and the rear support base 34 may be lifted or lifted together to be installed on the rear side 11 b of the loading platform 11.

The lorry 10 with the container device 2 is dispatched to the storage place of the rehabilitation pipe winding body 3X. As shown in FIG. 9A, the container 20 is arranged on the front side portion 11 a of the loading platform 11. As a result, the drum mount 40 on the rear side portion 11b (second side portion) of the loading platform 11 is opened upward. Preferably, the tilt 13 is defeated.
Subsequently, the rehabilitation pipe winding body 3 </ b> X is lifted or lifted by a crane or a forklift and placed on the drum mount 40. At this time, the lifting height or lifting height of the rehabilitation tube winding body 3X may be at least enough to exceed the rail 36 or the drum mount 40. There is no need to raise it higher than the upper end of the container 20, and it can be easily cleared even if there is a height restriction. Moreover, it can avoid that the rehabilitation pipe winding body 3X during loading / unloading collides with or catches the container 20, and can work easily and safely.
Next, the drum 50 and the drum mount 40 are connected by the fixing jig 56, and the turnbuckle 56c is tightened. Further, the roll 42 is stopped from rotating by pressing the rotation stopper 43 against the roll 42. Thereby, the rehabilitation pipe winding body 3X can be fixed to the loading platform 11.

Next, as illustrated in FIG. 9B, the container 20 is moved to the rear side portion 11 b of the loading platform 11. At this time, the rear door 24 of the container 20 (the door on the side facing the second side when in the first side) is left open. As shown in FIG. 1A, by placing the container 20 on the rear side 11b of the loading platform 11, the container main body 21 covers the rehabilitated tube winding body 3X and the rear support base 34, and the rehabilitated tube winding is performed. The attachment 3X is accommodated in the container 20.
In this manner, the rehabilitated tube winding body 3X can be easily put in and out of the container 20 relatively.
The container 20 disposed on the rear side portion 11b of the loading platform 11 is locked so as not to slide forward and backward by a lock mechanism (not shown). As a result, the container 20 can be stably fixed to the rear support base 34 and the cargo bed 11. By engaging the roller 25 with the rail 31 having a C-shaped cross section, the container 20 can be more stably fixed.
Moreover, the doors 23 and 24 are closed. By making the doors 23 and 24 double doors, the doors can be opened and closed reliably even if there is not much room in the height and width directions.
By closing the doors 23 and 24, the inside of the container 20 can be sealed. As shown in FIG. 1B, even after sealing, if the window 27 is opened, the drum 50 and the fixing jig 56 can be visually recognized, and the fixing state of the drum 50 by the fixing jig 56 can be confirmed. By operating the turnbuckle 56c, the fixing operation to the drum 50 can be performed again. Alternatively, it is also possible to hang the tying member 15 such as a sling between the rehabilitation pipe winding body 3 </ b> X and the left and right side hooks 14 of the lorry 10 through the window 27.
Thereby, the rehabilitation pipe winding body 3X can be reliably fixed to the loading platform 11.

  A hot air generator 61 and the like are mounted on the front support base 33. In addition, ducts 62 and 64 extending from the hot air generator 61 are connected to the container 20.

Thereafter, the lorry 10 is moved to the rehabilitation construction site of the buried pipe 1. Thereby, the rehabilitation pipe winding body 3X can be transported to the rehabilitation construction site in a state of being accommodated in the container 20.
Preferably, the rehabilitation pipe 3 in the container 20 is heated by the heating system 60 during the transportation. More specifically, hot air (heated air flow) is obtained by heating air in the air heating unit 61a of the hot air generator 61 and generating wind in the air blowing unit 61b. This hot air is blown out from the slit-like outlet 63 a of the outlet nozzle 63 into the room of the container 20 through the air duct 62. The hot air can heat (preheat) the inside of the container 20 and thus the rehabilitation pipe 3. The heated rehabilitation tube 3 becomes soft. Hot air can be blown out uniformly from each position in the longitudinal direction of the blower outlet 63 a, and the heated air can be spread throughout the container 20.
More preferably, the fan 68 and the blower 69 are driven. Thus, the air in the container 20 is agitated, so that the heated air can be sufficiently distributed in the container 20.
As a result, the rehabilitation pipe 3 can be heated uniformly and kept soft evenly.

The preheating temperature of the rehabilitation pipe 3 by the heating system 60 is preferably about 60 ° C to 70 ° C. If the temperature is lower than 60 ° C., the rehabilitation tube 3 cannot be softened. When it exceeds 70 degreeC, there exists a possibility that the shape recovery property of the rehabilitation pipe | tube 3 may express.
The temperature sensor 66 detects the temperature of the rehabilitation pipe 3 or the room temperature of the container 20 and feeds it back to a controller (not shown) of the hot air generator 61. When the detected temperature is below the desired temperature range (less than 60 ° C.), the controller turns on the air heating unit 61a. Further, when the detected temperature exceeds the desired temperature range (when it exceeds 70 ° C.), the air heating unit 61a is turned off. Thereby, the temperature of the rehabilitation pipe 3 or the room temperature of the container 20 can be adjusted to a desired temperature (about 60 ° C. to 70 ° C.).
The air in the container 20 is returned from the return duct 64 to the hot air generator 61 and heated again. Thereby, the heated air can be circulated between the hot air generator 61 and the container 20. The required amount of heat in the air heating unit 61a can be reduced and the heating efficiency can be increased compared to taking in external air and heating.
Furthermore, the heat release from the container 20 can be suppressed by the heat insulating material 67, and the heating efficiency can be further increased.

As shown in FIG. 4C and FIG. 10, after the freight car 10 is dispatched in the immediate vicinity of the start manhole 4 at the rehabilitation construction site of the buried pipe 1, the rear door 24 is opened. Further, the rear side wall plate 34d of the rear support base 34 is pulled up and removed (see FIG. 3). Further, the curtain 28 is closed as shown in FIG. Thereby, it is possible to prevent the heat in the container 20 from escaping.
It is not necessary to unload the rehabilitation pipe winding body 3X from the loading platform 11. Therefore, no crane or forklift is required.
In addition, when the lorry 10 cannot be put into the starting manhole 4 or the like, the rehabilitation pipe winding body 3X may be lowered from the loading platform 11 and carried to the starting manhole 4. In that case, after sliding the container 20 to the front side part 11a of the loading platform 11, the rehabilitation pipe winding body 3X is lifted or lifted by a crane or a forklift and is lowered from the loading platform 11. At this time, the lifting height or lifting height of the rehabilitation tube winding body 3 </ b> X only needs to be at least floating from the drum mount 40. Therefore, even if there is a height restriction, it is possible to avoid catching it.

Then, the rotation stopper 43 is set to the rotation allowable position, and the rehabilitating pipe 3 is sequentially fed out from the drum 50 and pulled out from the gap of the curtain 28 to the outside. By removing the rear side wall plate 34d, it is possible to avoid the rear side wall plate 34d from interfering with the withdrawal of the rehabilitating pipe 3.
By making the rehabilitation pipe 3 soft by preheating during the transportation, the rehabilitation pipe heating and softening process can be omitted after the arrival at the rehabilitation construction site, and the rehabilitation pipe 3 can be immediately fed out. Thereby, the construction period can be shortened.
The pulled out rehabilitation pipe 3 is inserted into the buried pipe 1 via the starting manhole 4. And the rehabilitation pipe | tube 3 is drawn in with the winch 5 and the wire 5w from the arrival manhole 4B side. Thereby, the rehabilitation pipe 3 is inserted and arranged over the entire length of the buried pipe 1.
Thereafter, the rehabilitation pipe 3 is heated to a shape recovery temperature (for example, about 70 ° C. or higher) with high-temperature steam or the like. Then, as shown to Fig.13 (a), the shape recovery property of the rehabilitation pipe | tube 3 will express, and the rehabilitation pipe | tube 3 will return to a circular cross section. Further, compressed air is put into the rehabilitation pipe 3. Thereby, as shown in FIGS. 11 and 12, the rehabilitation pipe 3 expands and is brought into close contact with the inner wall of the buried pipe 1. In this way, the buried pipe 1 can be rehabilitated.

The container apparatus 2 is removed from the used lorry 10. For example, the container 20 and the front support base 33 may be integrally removed after the container 20 is disposed on the front side 11a of the loading platform 11. Alternatively, the drum mount 40 and the rear rail portion 36 may be integrally removed in a state where the drum mount 40 and the rear support stand 34 are joined.
In this way, the container device 2 can be efficiently installed and removed from the truck 10.
As the truck 10, a general truck equipped with a loading platform 11 can be used.
