れている。2. Description of the Related Art For example, in a water intake and discharge facility of a dam, a tunnel (civil engineering structure) constructed as a temporary drainage channel is used.
In many cases, a water pipe is disposed inside the water pipe, and water is discharged through the water pipe. In this case, there are two types of installation methods for the water pipes (piping): a buried type that embeds in concrete, and a laid type that is installed in an exposed state using a mounting gantry. Has been adopted.

ならない。Conventionally, the mounting base used in this mounting method is generally in the form of a truss or a rigid frame, and when mounting a water pipe as an exposed pipe, the mounting base is fixed to the bottom of the tunnel. After that, while carrying the water pipe on the installation stand and performing its positioning,
The water pipe was fixed to the mounting base by an appropriate method such as welding or bolting. By the way, the water pipe is constructed by successively adding pipes of a certain length and extending the length of the pipe. (Concentric).

より一層困難なものとなっていた。However, according to the erection method using the above-mentioned mounting frame, since the mounting frame has a fixed size, the height of the upper surface changes due to unevenness at the bottom of the tunnel. A gap may be formed between the water pipe and the water pipe, or the water pipe may be unnecessarily lifted. Therefore, conventionally, adjusting members such as a spacer and a liner are prepared, and these are interposed between the installation stand and the water pipe, or the installation surface of the installation stand is excavated, and the height of the installation stand is increased. However, the degree of the adjustment differs depending on the installation location, and it is necessary to perform adjustment member processing, excavation, etc. while adjusting at the site, and it is unavoidable that the construction period is extended and the construction cost is increased. There was a problem. In addition, since the tunnel is usually constructed in a winding manner, the water pipe must be bent in accordance with the shape of the tunnel, and the air space in the tunnel is narrow. Construction work is
It was even more difficult.

Move it up to perform horizontal positioning. After the positioning of the water pipe 2 is completed, the joint between the pillar 14 of the lower gantry 4 and the pillar 17 of the upper gantry 5 is welded and fixed, and the cradle 6 is welded and fixed to the upper gantry 5. Thus, since all of these weldings can be performed in a downward position from above, welding workability is improved. Then cradle 6
One end of the upper water pipe 2 is joined to the water pipe previously erected, and a fastening band 21 is wrapped around the water pipe 2 on the receiving stand 6, and the mounting brackets 22 at both ends thereof are attached to the receiving stand 6. The bolts and nuts (not shown) passed through the bolt insertion holes 20 are fixed to the pedestal 6, thereby completing the installation of the water pipe 2. After the installation, loosen the jack 23,
It is removed from the installation device 3 and carried out to the next installation location.

For example, fixing by bolts and nuts, fixing by a clamp method, and the like can be adopted. Further, the structure in which the upper pedestal 5 is coupled to the lower pedestal 4 so as to be able to move up and down is also arbitrary. For example, instead of fitting the pillars 14 and 17 in the above embodiment, a guide bar extending from one side of the pedestal may be used. It is possible to adopt a structure in which it is inserted through a guide hole provided in the other stand. Further, in the above embodiment, the case where the water pipe 2 is erected in the tunnel 1 constructed in the intake and discharge facility of the dam is exemplified, but the application of the installation device and the erection method of the present invention are not limited thereto. Needless to say, the present invention can be applied to the construction of exposed piping used for various purposes.
