Description

Bulk-head Separation type Passway for refuge Evacuation}

The present invention relates to a partition type evacuation passageway, and more particularly, to a partition wall separation type evacuation evacuation passage having a short construction period and structurally stable.

According to the Road Tunnel Disaster Prevention Facility Installation and Management Guidelines (Ministry of Land, Infrastructure and Transport) revised on August 12, 2016, a face-to-face tunnel (tunnel in which vehicles alternate in both directions) or evacuation passages of level 3 (500-1000m) or higher is installed. For one-way tunnels that are not possible, a separate barrier type evacuation passage must be installed.Even in the operating tunnel, evacuation facilities cannot comply with the current guidelines, but only by adding a smoke-free facility in a face-to-face tunnel or one-way tunnel with a level 3 or higher extension standard In tunnels where the social risk caused by it exceeds the allowable limit, an evacuation passage with separation of bulkheads should be installed. However, if it is not possible to install an evacuation passage with separation of bulkheads due to civil engineering reasons, exceptions may be made through design deliberation in accordance with the Construction Technology Promotion Act.

The reason why it is obligatory to install an evacuation passage with separation of bulkheads is that when a vehicle in the tunnel is fired, there is more damage to people due to fire smoke rather than direct damage to people caused by flames, so an evacuation structure that blocks smoke and heat generated in the tunnel. This is to protect people in case of fire in the tunnel by providing a passage.

According to the guidelines for installation and management of road tunnel disaster prevention facilities, it is necessary to supply emergency lighting, guidance lights, and air necessary for life support, and to block the inflow of smoke into the evacuation passageway. Doors, etc. must be installed, and the facility limit of the evacuation connection passage should be 0.75m in width or more and 2.0m in height.

According to the above-described road tunnel disaster prevention facility installation and management guidelines, a bulkhead-separated evacuation evacuation passage is installed in the new tunnel, and as shown in FIG. 1, the wall 1 and the upper surface 2 are made of plain concrete. Unrefined concrete is constructed by the on-site pouring method, but for on-site pouring, there are many processes such as installation of copper bars, installation of formwork, installation of scaffolding, pouring and curing of concrete, scaffolding of formwork, and removal of copper bars, and there is a problem that the air increases. In addition, quality control is difficult if it is produced by the unrooted concrete on-site pouring method, but the width of the wall is narrow and the height is high, making it difficult to pour concrete, and it is difficult to sufficiently compact it. There is a problem of aesthetics and durability. In the case of fire, unrooted concrete may cause cracks on the concrete surface due to heat, and there is a problem in that it lacks resistance when it collides with a vehicle.

The present invention has been conceived to solve the problems of the above-described background technology, and the problem to be solved by the present invention is that it is possible to shorten the air and increase the area of the evacuation path by securing strength even with a thin thickness, It is to provide a partition-type evacuation path that is safe and excellent in landscape.

Afterwards, the mortar is also filled in the fourth coupling part 21 while moving the pouring position.

The coupling means 40 comprises the vertical panel 10 and the upper vehicle protective wall 5 of the tunnel, the vertical panel 10 and the horizontal panel 20, the horizontal panel 20 and the lining part 4 As a configuration for each coupling, as shown in FIG. 5, it includes an anchor bolt 41 and a nut 42 fastened to the anchor bolt 41.

An anchor bolt 41 that couples the vertical panel 10 and the upper vehicle protective wall 5 of the tunnel is installed in a manner that is buried in the upper vehicle protective wall 5 during tunnel construction, and is horizontal with the vertical panel 10 The anchor bolts 41 that couple the panel 20 are installed in a buried manner when manufacturing the horizontal panel 20.

A perforated part 43 is formed in the portion where the horizontal panel 20 and the lining part 4 are joined, and a chemical anchor bolt 41 is inserted to fix the anchor bolt 41.

The anchor bolt 41 is fastened with the nut 42 while passing through the anchor bolt holes 15 and 25, and a washer may be used if necessary.

Hereinafter, a method of constructing the above-described barrier separation type evacuation passage will be described.

First, the vertical panel 10 and the horizontal panel 20 are manufactured and transported in a precast method in the factory. By manufacturing the vertical panel 10 and the horizontal panel 20 in the precast method, the time required for installation and dismantling of structures such as scaffolds, formwork, and copper bars required for on-site casting can be expected, thereby reducing construction time. There is also an effect of being able to produce a structure with a much higher level of reliability compared to on-site casting.

Since the walls (vertical panels and horizontal panels) of the separation type evacuation passage must be able to sufficiently support the load caused by temperature changes, vibrations, and vehicle collisions inside the tunnel, the reliability of the strength is very important. The production of the precast method is a production method that meets these requirements.

When the vertical panel 10 and the horizontal panel 20 are transferred to the site, the vertical panel 10 is joined to the upper vehicle protective wall 5 by the coupling means 40, and the horizontal panel 20 is attached to the vertical panel. (10) and the lining part (4) is coupled by a coupling means.

In order to combine the vertical panel 10 with the upper vehicle protective wall 5, the anchor bolt 41 buried in the upper vehicle protective wall 5 during the construction of the tunnel is inserted into the anchor bolt hole 16 of the third steel plate 15. After passing through, the nut 42 is fastened to the anchor bolt 41. The vertical panel 10 and the horizontal panel 20 are coupled by passing the anchor bolt 41 formed on the horizontal panel 20 through the anchor bolt hole 16 and then fastening the nut 42.

In order to couple the horizontal panel 20 to the lining part 4, after the tunnel lining part 4 is constructed, a perforated part 43 is formed in the lining part 4, and a chemical anchor bolt ( After fixing 41), the nut 42 is fastened. In this case, a tapered washer may be used if necessary. In the case of the lining part 4, since it is often constructed of unreinforced concrete, there is no configuration for fixing the anchor bolts 41 like reinforced bars, so the perforated part 43 and the chemical anchor 41 are used.

When the arrangement and coupling of the vertical panel 10 and the horizontal panel 20 is completed, the reinforcing bar 50 is connected to the longitudinal reinforcing bar 24 exposed to the fourth coupling part 21, and the fourth coupling part 21 After the mortar 30 is poured on the 4-1 coupling part 21a side, the second coupling part 11 is filled with mortar, and the mortar 30 is poured into the fourth coupling part 21 while moving the placement position.

Due to this structure, the mortar 30 can be poured very conveniently, and the vertical panel 10 and the horizontal panel 20 can be combined. If the mortar 30 is to be separately poured into the second and fourth joints 11 and 21, the working time may be delayed, and the combination between the vertical panels 10 or the horizontal panels 20 Synthesis between the vertical panel 10 and the horizontal panel 20 is solidified because the mortar 30 is poured over the second and fourth joints 11 and 21. .

When the placement/curing of the mortar 30 is completed, the bulkhead separation type evacuation path is completed.

Although the detailed contents for carrying out the present invention have been provided by describing the preferred embodiments of the present invention above, it may be embodied as various types of partition-removable evacuation passages within the scope not included in the technical idea of the present invention.
