Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facility for constructing and moving a caisson, and more particularly to a facility for constructing a caisson on a platform within the reach of a crane and then moving the platform with the caisson. Regarding

[0002]

2. Description of the Related Art Conventionally, when constructing and moving a caisson, first, the caisson is constructed on a surface plate, and then the support base of the carriage mounted inside the pit of the identification plate is lifted by a jack. In addition to supporting, the carriage is moved using a drive mechanism such as a hydraulic cylinder. At that time, an operation of sequentially moving the hydraulic cylinder by strokes corresponding to the expansion and contraction of the hydraulic cylinder is performed.

[0003]

In the conventional caisson construction moving equipment as described above, it is necessary to form a truck insertion pit on the surface plate, and the caisson is moved using the truck in the pit. Therefore, there is a problem in that mechanical equipment becomes extremely complicated and its handling becomes difficult.

There is also a problem that the moving direction of the caisson is limited to the direction of the pit formed on the surface plate. The present invention is intended to solve such problems, and an object of the present invention is to provide a caisson construction moving facility capable of efficiently constructing and moving a caisson with a simple configuration.

[0005]

In order to achieve the above-mentioned object, the caisson construction moving equipment of the present invention can insert the levitation device of the caisson on the bottom surface of the construction table for constructing the caisson on the top surface. The above-mentioned levitation device, which is formed into a recess and is inserted into the recess, includes a support pad, a ring-shaped air bag, and
It is configured with a compressor for injecting compressed air into the inside of the air bag and the space on the inner peripheral side of the air bag,
Further, a drive mechanism for driving the building platform that has been levitated while the caisson is mounted by the levitating device to move it substantially horizontally is attached.

Further, the caisson construction moving equipment of the present invention is
The construction platform is characterized in that it is placed on a surface plate in the reach of the crane when the caisson is constructed.
Further, the caisson construction moving equipment of the present invention is characterized in that the drive mechanism is equipped as a double-body winch in which both ends of the construction platform are connected via wires.

[0007]

In the caisson construction moving equipment of the present invention described above, after the caisson is constructed on the upper surface of the building platform, the levitation device is inserted into the recess on the lower surface of the pedestal platform, and the ring shape of the levitation device is inserted. An operation of pressurizing compressed air into the inside of the air bag and into the space on the inner peripheral side of the air bag by a compressor is performed.

In this way, the construction platform that has been levitated while the caisson is mounted by the air press-in operation in the levitating device can be moved substantially horizontally in the required direction by the drive mechanism.

Further, when the above-mentioned construction platform is placed on the surface plate in the reach of the crane when the caisson is constructed, the caisson can be constructed efficiently by using the crane. After the construction of the caisson, an operation of moving the building table on which the caisson is loaded to the caisson carry-out place outside the reach of the crane is performed by using the floating device and the drive mechanism.

In this way, the building platform that has moved out of the reach of the crane is returned to the inside of the reach of the crane after the caisson is carried out by a crane ship or the like. If it is equipped as a connected multi-body winch, the reciprocating movement of the building platform can be performed very easily.

In this equipment, as shown in FIGS. 1 to 4, a caisson 3 composed of a caisson body 3a and a viscous body 3b such as an asphalt mat provided on the lower surface thereof is placed on a flat surface plate 4. It is designed to be built on the top plate 1a of the built platform 1, and before the construction of the caisson 3,
The building platform 1 is placed on a surface plate 4 in the reach R of the crane as shown in FIG. In FIG. 8, reference numeral 27 indicates the quay and 28 indicates the sea surface.

As shown in FIGS. 1 to 3, the building platform 1 is provided with supporting structures 2a, 2b, 2c for supporting the top plate 1a. The lower surface of the building platform 1 constructed in this way is As shown in FIG. 2, a plurality of recesses 5 are formed. Then, after the construction of the caisson 3, the levitating device 16 for levitating the building platform 1 with the caisson 3 mounted,
As shown in FIG. 4, it is designed to be inserted into the recess 5.

The levitation device 16 is shown in FIG. 5 (plan view) and FIG.
As shown in (a cross-sectional view taken along the line AA of FIG. 5), the air bag 21 is provided with a ring shape and the support pads 24 and 25, and the inside of the air bag 21 and the space 21a on the inner peripheral side of the air bag 21 are provided. Compressor that pressurizes compressed air through the air hose 17

Since the caisson construction moving equipment of this embodiment is constructed as described above, after the caisson 3 is built on the upper surface of the building table 1, the recess 5 on the lower surface of the building table 1 is constructed. The levitation device 16 is inserted into the levitation device 16, and an operation of pressurizing compressed air by the compressor 20 into the inside of the ring-shaped air bag 21 of the levitation device 16 and the space 21a on the inner peripheral side of the air bag is performed. As a result, as shown in FIG. 7, when the air bag 21 is inflated, the support pads 24 and 25 are separated from the surface plate 4, and the air pressure in the air bag inner circumferential space 21a is further increased. The air bag 21 is also slightly separated from the surface plate 4, so that the load of the building table 1 on which the caisson 3 is mounted is all supported by air pressure. If the compound winch 26 is operated in this state, the construction platform 1 will move to the caisson 3
It can be moved in the required direction almost horizontally with the mounted.

In this way, the building platform 1 which has been levitated while the caisson 3 is mounted by the air-pressing operation of the levitation device 16 can be moved substantially horizontally in the required direction by the multi-body winch 26 as a drive mechanism. . Further, since the building table 1 is placed on the surface plate 4 in the reach R of the crane when the caisson 3 is constructed, the caisson 3 can be efficiently constructed using the crane. After the construction of the caisson 3, the levitation device 16 and the winch 26 are used to mount the caisson 3 on the building table 1
Is moved to the caisson carry-out place near the quay 27 outside the reach R of the crane.

In this way, the building platform 1 moved out of the reach R of the crane is returned to the inside of the reach R of the crane again after the caisson 3 is carried out by a crane ship or the like. Since the multi-body winch 26 connected is equipped, the reciprocating movement of the building platform 1 can be performed very easily.
