In general, in order to construct horizontal tunnels such as underground waterways or underground tunnels, excavate vertical tunnels for work areas or ventilation facilities, and vertical tunnels to the ground for the entire period from the excavation of such vertical tunnels to the completion of construction. A steel structure is built around the entrance of the cube. And the steel structure is equipped with a winch (winch) to import / export all the necessary goods including the manpower and equipment for the construction of the vertical tunnel and the earth and sand.

On the other hand, in order to protect and stabilize the original ground of vertical tunnels excavated in the ground, concrete hollow walls are laid on the inner surface of vertical tunnels.In the past, concrete is installed after assembling formwork on part of vertical tunnels. It was then hardened, and the formwork was dismantled and reassembled to the next working position. Then, the work of pouring and curing concrete was repeated.

However, due to the lack of sufficient space for assembly and disassembly of the formwork inside the vertical tunnel, the work is very inconvenient. Especially, the worker who performs the aerial work in the excavated vertical tunnel falls down and In many cases, slip forms have been used, which allow continuous construction of the perforated wall while sequentially moving up and down the vertical tunnel.

Attached Figure 1 is a general vertical tunnel (T) and the slip foam 10 for constructing the perforated wall (2) to its inner surface, and the vertical tunnel (T), including the installation and disassembly and lifting of the slip foam (10) It is a schematic structural diagram which shows a part of the winch system 30 which imports / exports the various necessary goods including a manpower and equipment, and waste materials, etc. in the whole work of construction.

First, the slip foam 10 in the vertical tunnel T has an open shape on the upper surface thereof to provide a working space where the work can be performed by mobilizing people and equipment inside, and the vertical tunnel T along the outer circumference of the lower part. ) Is provided with a mold 18 defining a concrete pouring space at an interval between the inner surface and the inner surface.

In addition, the concrete input hopper 20 is exposed to the open top surface of the slip foam 10, and the concrete transfer pipe 22 extending therefrom passes through the side and is formed between the forming mold 18 and the inner surface of the vertical tunnel T. Exposed to the end, the concrete supplied to the input hopper 20 by the winch system 30 to be described later is discharged and poured through the transfer pipe 22 between the forming mold 18 and the inner surface of the vertical tunnel (T). In order to construct the perforated wall (2) sequentially.

In addition, a plurality of jack rods 4 are installed upright along the space between the slip foams 10 at the edge of the vertical tunnel T, and the jack rods 4 are respectively disposed on the outside of the slip foams 10. A plurality of cooperative yoke devices 16 are provided. At this time, each jack rod (4) can be extended coupling as necessary.

On the other hand, in the normal vertical tunnel (T), the winch system for carrying in / out of the necessary materials including equipment and manpower, including the installation and dismantling and lifting of the slip foam 10, and waste materials such as earth and sand ( 30), which is a winch (not shown) fixed to the steel structure of the cube surrounding the inlet edge of the vertical tunnel (T), and the vertical tunnel in the state suspended from at least three running wires 32 hanging therefrom (T) includes a work platform 40 to be elevated inside.

At this time, the work bench 40 includes a main work table 42 of the upper floor and an auxiliary work bench 44 of the lower floor which is coupled in parallel to the lower end thereof if necessary, and a concrete discharge hopper 46 for discharging concrete is provided at the lower end thereof. It may be provided.

Accordingly, when the loading and unloading of various necessary materials is completed, the respective decks 230 slide to approach each other to block the entrance of the vertical tunnel T as shown in FIG. 3, and then the traveling wire 132 is drooped to the work bench 140. Is seated on deck 230. Therefore, various necessary materials including concrete unloaded to each deck 230 is moved to the work bench 140, and then the work bench 140 is pulled up from the ground by the traveling wire 132.

Next, a pair of decks 230 are opened again in a sliding manner along each guide rail 240 to open the inlet of the vertical tunnel T, and the work bench 140 passes through the vertical tunnels of the underground ( T) It can deliver various necessary materials inside.

Through this process, when the work bench 140 having completed the transport of various necessary materials is recovered or the waste material in the vertical tunnel T is loaded to the work bench 140, the running wire 132 is pulled up again to the work bench 140. Comes out to the ground, and then the pair of decks 230 are close to each other to close the entrance of the vertical tunnel (T).

In addition, the corresponding work in the vertical tunnel T may be performed using the slip foam 110 or the like.

At this time, it is not essential to block the entrance of the vertical tunnel (T) during the corresponding work in the vertical tunnel, but to prevent the fall of materials, tools, and personnel, it is safe to block the entrance, and in this case, the vertical tunnel (T Inlet of the) is kept blocked by a pair of decks 230 and each safety net 250 is a safe operation.

On the other hand, the operation of the mobile deck apparatus 200 according to the present invention is applied to the assembly and disassembly of the slip foam 110, as well as the import / export of various necessary articles, as well as the discharge of waste materials, the end of the present The mobile deck apparatus 200 according to the invention can be utilized in the entire process of vertical tunnel (T) construction as needed.

As described above, when using a mobile deck device for the construction of a vertical tunnel according to the present invention, the construction of the vertical tunnel is completed once completed, unlike the conventional case of installing and releasing the temporary deck every time using a plurality of beams It can be used to the bar, it can greatly reduce the work yield and thereby has the advantage of saving the construction cost and shortening the air.

Furthermore, it can be used by simple operation such as pushing and pulling a pair of decks by sliding method, which has a more convenient advantage.

In addition, compared to the conventional, there is no need to move the concrete and various necessary materials to the vertical tunnel entrance far away from the steel structure structure, and simply by loading and closing the necessary materials on each deck positioned to be offset by the outer edge of the vertical tunnel entrance. There is an advantage that can be moved to the loading and unloading position.

And the pair of decks according to the present invention described above can be opened only when necessary and closed in other cases to reduce safety accidents caused by falling and falling of materials through safety nets, and steel frame installed at the entrance of the existing vertical tunnel Because of the structure, it has the advantage of being simple and easy to install.

Thus, the vertical tunnel construction can be carried out more safely and conveniently.
