があった。However, according to the above-mentioned conventional duct mounting work, it is not only difficult to perform the lifting work inside the tunnel where the size of the space is limited, but also the hoisting machine lifts it up. At the same time, a scaffold for workers was required to attach the duct to the top of the tunnel inner surface, and the assembling work and the refilling work of the scaffold were extremely troublesome. Also, working in high places on a narrow scaffold is dangerous,
It is difficult to position the duct hoisted by the lifting machine at the mounting location, and it is not easy to fix it to the support metal fittings. Therefore, there have been problems of reduced efficiency of duct installation work and danger.

スも確保し難い問題がある。Further, when the duct mounting work is carried out in parallel with the concrete pouring of the invert (drainage), the finishing of the inner surface of the tunnel, the excavation work, etc., a material carrier truck or a railcar laid inside the tunnel is used. Sediment dump trucks often run, and battery trucks and agitator trucks also operate constantly. Under such circumstances, installing a lifting machine in the tunnel will be an obstacle and also the installation space for the above-mentioned scaffolding scaffolding. There is a problem that is difficult to secure.

ある。As a technical means for achieving this object, the present invention is a work cart formed so as to be movable on a dedicated rail laid through a sleeper that is laid horizontally in a tunnel. This work trolley lifts the duct attached to the top end of the inner surface of the tunnel, and the duct lifting and moving means for moving to the attachment position of the duct, and the sleeper removal for sequentially removing the sleepers while retreating after the completion of the duct installation. The gist of the present invention is a work trolley provided with means. Further, in this work carriage, the duct lifting and moving means is composed of a plurality of electric chain blocks mounted on the work carriage, and these electric chain blocks move in the front-rear direction along guide rails provided on the work carriage. The sleeper removing means includes a pair of horizontal support members provided in the front-rear direction at the end of the work carriage, a horizontal member that moves in the front-rear direction along the horizontal support members, and a horizontal member. An electric chain block for removal, which moves laterally along the vertical axis and turns by 90 degrees about a vertical axis; and the work trolley comprises a base and a substantially yagura attached below the base. -Shaped legs, and a workbench oppositely installed on the base in the front-rear direction, the base has an opening for passage of a duct, and the lower end of the leg is on a dedicated rail. To run A wheel is provided, the dedicated rail is laid wider than the rail width so as to straddle the rails on which other trucks etc. travel, and inside the space sandwiched by the almost wagging legs of the work truck. Other trolleys and the like can pass through, and the work trolley is driven electrically
The stop is characterized by inverter control.

台車が邪魔にならない。The dedicated rail on which the work carriage travels is laid so as to be wider than the rail width so as to straddle the rail on which other carriages travel, and the legs of the base are substantially wobbled. Therefore, another truck or the like can pass through the space surrounded by the legs. As a result, the work carriage does not get in the way even when the duct installation work and the other tunnel work are performed in parallel.

採用すると荷振れを低く抑えられて好ましい。The operation of attaching the duct 2 to the top end of the inner surface of the tunnel 1 with the work carriage 5 thus constructed will be described. As described above, the work carriage 5 is driven electrically, and is connected to a power source (not shown) via a cable. The cable is attached to the lower end side portion of the leg portion 8 of the work carriage 5. It is wound around the cable reel 20. Inverter control is preferably used for starting / stopping the movement of the work vehicle 5 because the shake of the load can be suppressed low.

The lifting is stopped when the upper end of the is close to the top surface of the tunnel 1. The positional relationship between the position of the duct 2 and the mounting position is determined, and if the position is deviated, the electric chain block 13 is moved along the guide rail 12 to position the duct 2. After that, the support fitting 1
The duct 2 is fixedly attached to the top end surface of the tunnel 1 via 4.

At the same time, the duct is positioned and then attached and connected to the duct previously attached. By repeating such work, the ducts can be sequentially attached and fixed to the top end surface of the tunnel 1.

In this case, the duct 2 is directly lifted from the transport carriage, but as another method, for example, the duct carried by the transport carriage is placed on the rail 6 before the work carriage 5 and temporarily placed, and It is also possible to move 5 and position it on a temporarily placed duct to lift it up sequentially.

ことができる。Even when the duct mounting work is performed in parallel with the inner surface finishing of the tunnel 1 or the excavation work, the material carrier or the earth and sand carrier travels on the rail 6 and the space S of the work carrier 5 moves. Since it can pass through the inside, the work carriage 5 does not get in the way in the tunnel 1. Therefore, the duct installation work and the other tunnel work can be efficiently performed in parallel.

After retracting the work carriage 5 by a predetermined distance, the dedicated rails 4 and 6 located in front of it are removed from the sleepers 3. These rails usually have a unit length of about 5 m. For example, the sleepers 3 are removed with the unit length as one section.

The following excellent effects can be obtained. When a duct is attached to the top of the tunnel, the work trolley equipped with duct lifting and moving means and sleeper removing means can run on the dedicated rail laid through the sleepers, so it can be moved up and down. The duct can be attached efficiently by hoisting the duct by the means and easily positioning the duct at the attachment point. The dedicated rail on which the work trolley travels is laid wide so as to straddle the rail on which other trolleys travel, and the work trolley is configured so that other trolleys, etc. can pass through the space between the legs. Therefore, the work carriage does not get in the way in the tunnel, and it is possible to perform the duct installation work and the other tunnel work in parallel. By mounting the duct on the carrier truck and running it on the rail, the duct can be positioned on the work truck and the duct can be directly lifted from the carrier truck, so that the mounting work can be performed efficiently. In addition, lower the duct from the carrier and place it temporarily.
Since the ducts can be lifted up sequentially while moving the work cart, the installation work of the next day can be sufficiently handled and the work is not wasted. Since the work platform is provided on the upper part of the work cart, the conventional assembly type scaffolding is not required, and the space is wider than the conventional assembly type scaffolding. It is possible to improve the efficiency of duct installation work and ensure worker safety. After the duct installation is completed, the sleepers can be sequentially removed by the sleeper removing means while retreating the work trolley by a predetermined distance, and the removed sleepers can be loaded on the transport trolley and run on the rails to quickly get out of the tunnel. It can be carried out. As a result, the duct installation work and the sleeper removal work can be efficiently performed by one work carriage. Since the work trolley is driven electrically, it does not deteriorate the working environment in the tunnel, and the inverter control is used to start and stop the movement of the work trolley to keep the load swing when removing sleepers low.
