As shown in Figure 1, the rail (3) is thrown from the upper tunnel (1) to the lower end of the inclined shaft 42, and the single pipe (4 m) is carried in from the loading port (5) of the upper tunnel +11 to the cart (6). put it on,
Use the quinch (7) to transport the single pipes (41) to the installation location, and in the same way, one after another the single pipes ('h '3t '4,
) was brought in, and the brought in single pipe (4gm43e'4
...) were installed by welding them to the pipes that had already been installed. By the way, a single pipe ('1eG) that can be carried into the inclined shaft (2)
The length of 3" is limited by the size of the inclined shaft (2), and as the pile length increases, the length of the single pipe (41

、従来工法ではなし得なかった効果を有する。The present invention has been made in response to this demand and to eliminate the above-mentioned drawbacks.The present invention is characterized by providing a large block manufacturing facility at a suitable location in the upper part of the inclined shaft, and by installing a plurality of single pipes from the upper shaft into the inclined shaft. are lowered in order, and the single pipes are joined together in the above-mentioned manufacturing facility to manufacture a large block, and the large block is lowered and installed at a predetermined installation position, and an appropriate number of large blocks are manufactured in the same manner. lower it,
The method involves manufacturing an iron pipe by joining large blocks together, and then filling the gap between the iron pipe and the inner surface of the inclined shaft with a filler material. According to this construction method, the single pipes are not transported to the installation location one by one as in the conventional method, but are transported to the installation location as a large block, which significantly reduces the number of times the pipes are transported to the installation location, which improves work efficiency. This reduces the need for joining work in poor installation locations. In addition, by setting up a large block production facility exclusively for joining, the work of joining single pipes and filling work with filler material can be done simultaneously, reducing the amount of time on hand and shortening the process. can be achieved. In addition, specialized joining equipment such as automatic welding machines can be installed in the manufacturing site, making it possible to improve joining quality. Furthermore, since the number of times of going up and down to the installation location is small, it improves safety and work efficiency, and also leads to improved economic efficiency, which has effects that could not be achieved with conventional construction methods.

する。As described above, according to the present invention, single pipes are not carried to the installation position one by one as in the conventional method, but are carried to the installation position as a large block, so the number of times the pipes are carried to the installation position is significantly reduced. This reduces the need for joining work at installation locations where workability is poor. In addition, by setting up a large block production facility exclusively for joining, the work of joining single pipes and filling work with filler material can be done simultaneously, reducing waiting time and shortening the process. can be achieved. In addition, specialized joining equipment such as automatic welding machines can be installed in the manufacturing site, making it possible to improve joining quality. Furthermore, since the number of times of going up and down to the installation location is small, safety and work efficiency are improved, and economical efficiency is also improved, which has effects that could not be achieved with conventional construction methods.
