ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an installation method for installing iron pipes such as penstocks by excavating a diagonal tunnel underground. This relates to an iron pipe installation method in which unit iron pipes are brought in, sequentially welded at the intersection of a diagonal shaft and a work shaft, and then moved and installed at a predetermined position.

する欠点があつた。 Conventionally, when installing a penstock in a diagonal shaft tunnel, a unit iron pipe consisting of 6 to 9 m long iron pipes is brought into the tunnel, installed at a predetermined position, and the ends of the unit iron pipe are connected to each other from both the inside and outside of the iron pipe. Since the penstock was welded to a long penstock, it was necessary to excavate a tunnel with a diameter 120 to 140 cm larger than the diameter of the iron pipe so that workers could enter around the iron pipe for installation, welding, inspection, etc. Ta. After the iron pipes are welded, the gap between the iron pipe and the tunnel is filled with concrete, but because a tunnel with a diameter much larger than the diameter of the iron pipe is excavated and then filled with concrete, the conventional method of installing penstocks is difficult. It had the drawback of requiring a large amount of construction costs.

ストが嵩むという欠点がある。 Therefore, in order to reduce construction costs by excavating a tunnel with as small a diameter as possible and installing the iron pipe inside it, instead of the conventional welding method in which the iron pipe is welded from both the inside and outside of the iron pipe, welded only from the inside of the iron pipe. A method of welding iron pipes using so-called Uranami welding has been proposed. According to this construction method, there is no need for welders to enter between the outside of the iron pipe and the inner wall of the tunnel to perform welding work, so it is only necessary to excavate the minimum tunnel necessary for introducing the iron pipe. and filling costs can be saved. However, since Uranami welding only welds from the inside of the iron pipe,
Compared to the method of welding from both the inside and outside, this method has the disadvantage that the welding work is difficult, and in order to perform complete welding, automated large-scale welding equipment is required, which increases welding costs.

る。 In view of the above-mentioned drawbacks of the conventional construction method, the present invention sets the diameter of the tunnel as the minimum required dimension for moving the iron pipe, thereby reducing the cost of tunnel excavation and filling. The purpose of the present invention is to provide a method for installing penstocks that allows manual welding to be performed at low cost and with good quality.

の作業を繰り返す工法である。 In general, in the case of inclined shafts of iron pipeline tunnels, work shafts are provided every 200 to 300 meters along the inclined shaft to carry out excavation waste and to carry in iron pipes.
In the construction method of the present invention, the diameter of the inclined shaft is set to the minimum dimension necessary to move the iron pipe up and down along the inclined shaft, and the cross section of the inclined shaft is removed from the working side shaft only near the intersection of the inclined shaft and the working side shaft. The steel pipes are cut and widened to a size that can be easily carried in, welded, and inspected, and the unit iron pipes of a certain length are brought in from the working side shaft and cut and widened at the intersection of the sloped shaft and the working side shaft. The unit iron pipes are completely welded by hand welding from both the inside and outside of the pipe, and by lifting equipment such as a winch installed at the top of the inclined shaft, the length of the entire welded iron pipe is lifted each time one unit iron pipe is welded. The steel pipes are then hoisted upward and moved, and successive unit iron pipes are welded to the lower ends of the pipes to extend the total length. When the length of the steel pipe between the work shafts of the inclined shaft is completed, it is lowered and placed in the designated position. This is a construction method in which the same work is repeated at the intersection of the horizontal shaft and inclined shaft on the next upper level.

At the intersection 7 of the inclined shaft 1 and the working horizontal shaft 6, both shafts are widened so that work such as carrying in unit iron pipes 8 and welding can be easily carried out. Rails 10 are laid in the work shaft 6 in order to place the unit iron pipes 8 on an assembly table 9 and carry them there. As shown in FIG. 3, the assembly table 9, on which the unit iron pipes 8 are placed and carried in by rolling on the rails 10, can rotate about a fulcrum 11 to an oblique position.

Assembling the unit iron pipe 8 from the second stage working horizontal shaft 6 to the assembly table 9
At the intersection 7 of the working horizontal shaft 6 and the inclined shaft 1, as shown by the chain line in FIG. The unit iron pipe 8 is tilted so that its axis is parallel to the inclined shaft 1, and the unit iron pipe 8 is lowered from the lifting equipment 4 such as a winch at the top 12 of the inclined shaft by a wire 13.
It is placed on the trolley 5 to a position slightly higher than the length of one line and pulled up along the incline rail 3. The next unit iron pipe 8 is carried in and placed on the assembly table 9, the assembly table 9 is tilted, and the iron pipe previously pulled up into the inclined shaft 1 is lowered a little and the tube ends are aligned. Next, the joint part 14
Weld by hand or machine welding from both the inside and outside of the tube. After inspecting the welded part, the entire welded iron pipe 2 is lifted up by the lifting equipment 4 by about the length of one unit iron pipe. By repeating the same operation, the unit iron pipes 8 brought in one after another are welded to the iron pipes 2 in the inclined shaft 1 and extended. When the length of the A section of the inclined shaft 1 between 6 and 6 is reached, the incline rail 3 is assembled at the intersection 7, and the entire iron pipe 2 of the A section that has been pulled up is moved across the intersection 7 to the predetermined installation position. hang it down The iron pipe 2 is installed in the correct position, the gap between the iron pipe 2 and the tunnel is filled with concrete, and the installation work for section A is completed. When filling concrete, the incline rail 3 is also buried.

を終了する。 Similarly, for section B, the iron pipes are brought in using the third-stage work shaft 6, welding is repeated at the intersection 7', and iron pipes 2 equal to the length of section B are assembled. Lower it to the designated position. The lower end of the iron pipe in section B is brought into contact with the upper end of the iron pipe in section A,
The iron pipes in both sections will be connected by welding or mechanical joints. Next, the gap between the steel pipe in section B and the tunnel is filled with concrete, and the installation work for the steel pipe in section B is completed.
このようにして、順次N個の区間について据付

い。 In the above explanation, the unit iron pipes 8 constituting the iron pipes 2 to be installed in each section are carried in through the work shaft 6 that intersects at the upper end of the section of the inclined shaft to be installed, and welded at the intersection 7. However, when the entire section is connected to one iron pipe and lifted, the unit iron pipe 8 is carried in from the working horizontal shaft 6 that intersects at the bottom end of each section, contrary to the above, and the working horizontal shaft is Pit 6 and inclined shaft 1
A method of welding at the intersection 7 can also be used in exactly the same manner. In particular, for the uppermost section of the inclined shaft 1, it is preferable to use the latter method since there is no room to lift the entire connected iron pipe upward. If the uppermost section is to be constructed in sections, it is best to excavate a wide tunnel for only the uppermost portion of the divided sections and install the iron pipe using conventional construction methods.

Furthermore, the assembly table 9 may be moved on the rails 10 laid in the work shaft 6, and the unit iron pipes 8 may be loaded thereon and carried in. Alternatively, the assembly table 9 may be fixed at the intersection 7. Then, the unit iron pipe 8 may be carried in using another cart and transferred onto the assembly table 9.
