Description

{FOUNDATION CONSTRUCTION METHOD FOR EMERGENCY CLEARWAY}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a base construction method for an emergency evacuation passage, and more particularly, to a base construction method for an emergency evacuation passage in which an evacuation of a passenger along an underground tunnel is enabled when an emergency occurs during operation of the subway.

Generally, the subway has evacuated the passengers by manually switching the automatic gate to jump off the track when the vehicle is stopped between the station and the station so that the passengers are stopped by the emergency stop between the station and the station. As a disaster prevention facility to safely evacuate the track again, an emergency exit was formed at a certain distance to evacuate the evacuation passenger to the emergency exit.

However, when the vehicle stops at the station when the vehicle is stopped after an emergency stop, the door and the opposite platform of the vehicle are raised at the same height, so that there is no difficulty in evacuation. However, There is a difference of more than 1M between the floor of the track and the height of the door, so it is necessary to jump off from a narrow place. In case of women, children and elderly people, In addition, even if the vehicle is escaped from the vehicle because the track is dark, it can not be moved quickly, and a railroad track is formed to support the rail, thereby hindering rapid movement and causing many people to suffer damage.

On the other hand, as a conventional technique for solving such a problem, a utility model registration No. 357539 discloses a technique relating to a passage for emergency evacuation of a subway.

However, in the above-mentioned prior art, since the supporting frame for supporting the foot structure is fixed to the side wall surface, there is a limit to the load supporting force, and at the same time, there is a safety accident such that the foot plate is seated when the user moves through the emergency evacuation passage .

The present invention has been proposed in order to solve the above problems of the prior art, and it is an object of the present invention to provide a construction method capable of maximizing load bearing capacity of a foundation supporting an emergency evacuation passage, thereby enhancing structural stability, To be able to do so.

According to another aspect of the present invention, there is provided a method of installing a base plate, the base plate including a base plate having a plurality of bolts vertically arranged on a top surface thereof, A computer bolt supporting step of supporting the plurality of bolts by separate supporting means; Placing a concrete on an upper surface of the base plate so that an upper end of the bolt can protrude at a predetermined height; A column support is provided on the poured concrete, the passage support comprises a lower plate having bolt fastening holes for bolt fastening with the bolts, and an upper frame for supporting the passage fasteners, .

In the basic construction method for a subway emergency escape passage of the present invention, since the foundation structure for installing the emergency escape passage is stably installed on the bottom surface of the tunnel, the load bearing capacity of the escape passage is maximized to enable safe movement of the passenger in an emergency .

Particularly, since the computer bolts are connected and supported by separate support means in the concrete supporting the column structure, the occurrence of adverse effects of the bolts due to shrinkage and expansion of the concrete is minimized.

<Concrete pouring step> (ST 3)

Thereafter, the concrete 20 is poured into the upper surface of the base plate 10 as shown in FIG. 4 so as to cover the intermediate portion of the bolt 11.

At this time, the height of the concrete 20 is adjusted so that the upper end of the bolt 11 is partially exposed.

<Stage of installing struts> (ST 4)

When the installation of the concrete 20 is completed, the passageway struts 30 are installed. At this time, the bottom plate 31 provided at the lower portion of the passageway struts 30 is supported by the bolts 11 .

That is, the passage post 30 in this embodiment has a lower plate 31 formed with bolt fastening holes 31a so as to be bolt-fastened to the bolts 11 as shown in FIG. 5, The bolt fastening hole 31a is formed with the upper frame 32 integrally formed thereon and the bolt 11 is inserted into the bolt fastening hole 31a, As shown in Fig.

7 and 8, the pedestal 40 is seated and fixed to the upper part of the passageway strut 30, so that the emergency escape The installation work of the passage can be completed.
