Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slab installation method and a slab installation method,

In particular, the present invention relates to a wind slab installation method using a bogie for installation of wind slabs, and more particularly, to a wind slab installation method capable of stably installing a wind slab in a section where a wind tunnel is installed, The present invention relates to a method of constructing a wind slab using a bogie.

Tunnel structures (underground roads, underground tunnels, etc.) are used for tunnel ventilation considering efficiency in accordance with traffic volume and tunnel length in order to protect tunnel users from emergency situations such as smoke, harmful gas, dust, Equipment. In addition, since the air pollution due to the automobile exhaust gas flowing in the inside of the tunnel structure seriously affects the tunnel passenger and the human body of the driver, the ventilation equipment required by the appropriate ventilation calculation should be provided to prevent this.

Natural ventilation system, type system, semi-transverse system, and transverse system are applied to the tunnel. In case of semi-transverse type and transverse type, ventilation is performed by installing wind-induced slab in the tunnel.

Generally, the wind slab is installed in the tunnel underground using a crane. However, when a step 6 protruding downward as shown in FIG. 8A is formed at the end portion of the wind tunnel slab installation section of the tunnel, the crane boom can not be installed in the rectangular section L ). Therefore, a device or equipment capable of installing a wind slab in a rectangular section of a tunnel that can not be installed by a crane is required.

As a background of the present invention, Korea Registered Patent Registration No. 10-1478561, 'Monorail system for precast wind slab construction for tunnels and tunnel construction method using the same' has been proposed. It consists of a rail longitudinally formed at the top of the lined tunnel; A support frame disposed on the rail and rotated along the rail, the support frame being moved forward or rearward of the tunnel in accordance with rotation of the wheel; A plate-shaped upper frame secured to a lower portion of the support frame by a support shaft connected to a center of the support frame; A plate-shaped lower frame connected to the upper frame at a lower portion of the upper frame; And a plate-shaped rotary frame fixed to a lower portion of the lower frame, the plate frame being relatively rotated with respect to the lower frame and stacking a wind-induced slab to be installed in the tunnel.

This has a problem in that the construction of the system is complicated, while the construction time is shortened by simultaneously performing the tunnel lining work, the rail installation work and the pier installation work and the wind slab installation work using the monorail system at the same time in parallel.

Another technology to be a background of the present invention is Korean Patent Registration No. 10-1465398, which proposes a wind tunnel slab construction method and a wind tunnel slab construction method using the same. This is accomplished by providing a transmission cable provided on the ceiling of the tunnel along the longitudinal direction of the tunnel; A lifting unit including a moving unit that moves along the longitudinal direction of the conveyance cable, a rotating unit that is rotatably provided at a lower portion of the moving unit, and a lifting unit that is vertically movable from the rotating unit to lift the air- The transport cable includes: a first cable moving along the longitudinal direction of the tunnel to move the moving unit; And a second cable for guiding movement of the moving part while being fixed to the ceiling part of the tunnel.

Therefore, while the lifting slab has the advantage of facilitating the construction of the wind slab by using the lifting unit that is moved and rotated about the longitudinal direction of the tunnel by the transport cable, the wind slab must be transported from the loading position to a position farther away It is difficult to shorten the air due to the longer overall travel distance. In addition, there is a problem that a wind slab can not be installed in a certain section if there is a step at the end of the wind slab installation section.

The pair of truck bodies 12 and 12 have the same configuration.

As shown in Figs. 1 and 2, the pair of bogie bodies 12 and 12 have hydraulic jacks 14 and 14 for bogie lifting and descending, respectively, provided at two positions in the vertical direction. Therefore, the wind-load slab installing truck 10 has a structure in which four hydraulic lift jacks 14 are installed at four places in plan view.

The bogie main body 12 is moved upward while the bogie lifting hydraulic jack 14 is extended and the bogie main body 12 is moved down when the bogie lifting and lowering hydraulic jack 14 is contracted.

The wheel mounting frame 16 is integrally joined to the ends of the operation ends 141 and 141 of the vehicle lifting and lowering hydraulic jacks 14 and 14. In the wheel mounting frame 16, traveling wheels 15 and 15 are rotatably mounted. Driven gears 151 and 151 are coupled to the rotating shafts of the traveling wheels 15 and 15, respectively.

[ The traveling hydraulic motor 18 has a drive gear 181 engaged with the driven gears 151 and 151. Therefore, the direction of rotation of the traveling wheels 15 and 15 is selected in accordance with the driving direction of the traveling hydraulic motor 18, and the running direction of the wind-induced slab installing truck 10 is determined.

As shown in Fig. 3, the hydraulic jacks 20 for wind-induced slab clamps are mounted at two positions for each of the jack base plates 122 and 122. [ The hydraulic jack 20 for the wind direction slab clamp has a lifting ring 21 connected to the lifting slab 7 side lifting anchor 7a at the working end 201 thereof. Here, the operation end 201 is allowed to move up and down freely through the jack base plate 122.

A hydraulic pump 22 is mounted on each of the jack base plates 122 and 122. The hydraulic pump 22 supplies the hydraulic oil to the hydraulic jacks 14 and 14 for raising and lowering the car, the hydraulic motor 18 for driving, and the hydraulic jack 20 for the windshield slab clamp through the unillustrated hydraulic pipeline.

On the other hand, the air bearing slab installation truck 10 may further include a pair of bearing steels 124 and 124 on the lower surface of the jack bearing plate 122. The pair of bearing steels 124 and 124 are arranged in parallel with each other in the width direction of the air-bearing slab 7 placed in the conveying position, avoiding the position of the operation end 201 of the hydraulic jack 20 for the air-bearing slab clamp.

In addition, the air-bearing slab mounting truck 10 may further be equipped with a buffer pad 126 to protect the impact against the air-bearing slab 7 when clamped on the lower surface of the pair of bearing steels 124, 124. The buffer pads 126 may be made of rubber, for example.

On the other hand, a balancing wheel 128 (not shown) is provided on one side of the jack-receiving plate 122 for balancing when the wind-load slab-installing baler 10 is returned to its original position, ) Is further preferably installed. The balance wheel 128 may be mechanically slid by the jack base plate 122 or may be moved using the cylinder 129 to contact the upper surface of the wind slab 7.

<Wind Slab Lifting and Clamp>

Next, as shown in Fig. 1, the traveling hydraulic motor 18 is driven in one direction to move to the laminated wind slab side in a state in which the wind slab installing truck 10 is raised to a certain height by using the elevating hydraulic jack 14 After the lifting hook 21 is connected to the air-conditioned slab 7 on which the two floors are stacked, the air-conditioner jack 20 for the air-conditioned slab clamp is operated so that the air-conditioned slab is lifted upward and clamped to the side of the truck body 12.

<Forward travel>

Then, as shown in Fig. 5, the hydraulic motor 18 for driving is driven in the other direction to install the wind direction slab, and the wind direction slab installing truck 10 is moved forward to the target position.

<Unclamping and Air-Slab Mounting>

Subsequently, the balustrade slab installation truck 10 is lowered by operating the hydraulic jack 14 for elevating and lowering as shown in Fig. 6, and the hydraulic jack 20 for the wind slab clamp is descended and unclamped, And are placed on the support plates 5a and 5b.

<Retreat driving>

Next, as shown in FIG. 7, the lifting ring 21 connected to the wind direction slab is removed, and the balance wheel 128 is grounded to the wind direction slab 7 and then returned to the retreat position.
