Description

{A Great deep metro station structure}

The present invention can provide a comfortable and convenient use of passengers and a quick and safe evacuation in an emergency in a subway station, which includes a subway platform constructed underground and a waiting room installed near the ground, At the same time, it is about the subway station structure that can be constructed economically.

The subway is a useful means of transporting many passengers quickly and safely to their destinations, and the number of passengers is increasing day by day. In accordance with this trend, metro construction is increasing in the metropolitan area as a means of solving traffic problems, promoting balanced development of the city, and fast and safe transportation of passengers, and at the same time, the depth of construction is deepening.

In the case of such a deep subway, the subway platform needs to be constructed in such a way that it can be used economically and comfortably for the passengers to use, can get on and off quickly, and can be safely and quickly evacuated in the event of an emergency such as a fire.

The construction method of the subway station can be divided into the construction method and the tunnel method. The tunnel method can be divided into the slope gang construction method and the steel bridge method.

The construction method is a construction method that constructs the waiting room and the platform in one body by directly excavating from the ground to the lower part. It is simple in construction method, and it is possible to secure smooth entry and exit between the platform and the waiting room, There are problems such as long-term traffic control, noise caused by rock blasting, interference of underground obstacles, adverse effects on surrounding structures.

One of the methods for improving the problem of the installation method is to excavate a tunnel in an oblique direction from an earth surface to an underground station at a large depth and to install an escalator or the like in the tunnel in the oblique direction so as to move the passenger.

The inclined gang construction method minimizes the influence on the ground structure and can reduce the traffic control. However, since construction of crosses and shafts is complicated and construction cost is excessive and passengers are moved mainly through the escalator, There is a problem that the quickness is deteriorated and the evacuation time to the ground is increased particularly in an emergency. In addition, the gang construction method requires a special evacuation staircase for each platform in addition to the escalator for emergencies. Therefore, even if the construction cost is increased and an emergency exit or a special evacuation staircase is used, the evacuation time It may be below this standard.

Another method, the orthogonal method, is a method of excavating a tunnel vertically from the surface of the earth to the underground station of the large depth and constructing an elevator of a large grave in the vertical tunnel to move passengers.

The above-mentioned orthogonal method is advantageous in that it is less influenced by obstacles during construction, reduces traffic control, and allows passengers to move quickly through an elevator. However, since the special evacuation stairs need to be installed separately for each platform, the construction cost is increased, and it is not easy for a large-scale passenger in an emergency to evacuate using a special evacuation staircase.

The subway station structure according to an exemplary embodiment of the present invention is a structure constructed by an erection method among subway station construction methods, and can be applied mainly to the construction of a subway station of more than 30m.

This embodiment includes a platform 10 installed underground for passengers on / off the subway, a waiting room 20 installed above and below the ground surface and / or the ground surface of the platform 10, A passenger conveyance passage 30 vertically installed up to the depth of the landing 10 and a connecting passage 40 provided between the landing passage 10 and the passenger conveyance passage 30, A plurality of elevators 32, and an emergency staircase 34, which are installed along the elevator.

The platform (10) is a place where the passengers of the subway map ride or get off the train and are installed underground. The landing platform 10 can be installed at the center of the reciprocating rail or at both sides of the reciprocating rail and is usually provided on both sides of the reciprocating rail.

The waiting room 20 may be installed above the landing surface 10 and / or below the ground surface. That is, it may be installed on the ground surface, on the lower side of the ground surface, or on the lower surface of the ground surface and the ground surface.

The passenger conveyance passage 30 is a passage through which the passenger moves from the waiting area 20 to the landing position 10 and can be vertically installed from the waiting area 20 to the landing position 10 in this embodiment.

The connecting passage 40 is provided between the landing platform 10 and the passenger conveying passage 30 and is a passage through which the passenger moves between the landing platform 10 and the passenger conveying passage 30.

The passenger conveyance passage 30 may be provided with a plurality of elevators 32 and emergency stairs 34 for conveying passengers along the wall. In the case of this embodiment, it is preferable to provide a plurality of elevators 32 of a large capacity so as to transfer a large number of passengers.

Further, the connection passage 40 may be provided below the landing platform 10. [ Therefore, the passengers getting off the platforms 10 on both sides descend to the connecting passage 40 below the landing platform 10 by using a staircase, an escalator or an elevator, and then pass through the passenger conveying passage 30 And the elevator 32 can be used.

When the connecting passage 40 is installed on the lower side of the landing platform 10, it is possible to delay the time required for the smoke caused by the fire or the like generated in the landing platform 10 to move to the connecting channel 40. In other words, in the case of smoke, it is moved to the upper side first, and accordingly, the connection passage 40 located at the lower side arrives later to secure the passenger's evacuation time, thereby minimizing the casualty damage.

A fire shutter (42) may be installed in the connection passage (40) or the landing platform (10). That is, the fire retarding shutter 42 can be installed at a proper position on the connecting passage 40, at a suitable position on the landing platform 10. The obstacle shutter 42 must secure a necessary space in accordance with the passenger demand so that it is possible to prevent the passenger 40 from coming to a position where the passenger conveyance passage 30 and the connecting passage 40 are in contact with each other, Or at the lower connection point of the escalator, at the upper end of the staircase or the escalator, at a certain space at the upper end of the staircase or the escalator, at the point where the platform is divided into longer portions.

The front chamber 46 may be provided where the fire retarding shutter 42 is installed. A double door is provided on the front and rear of the front chamber 46, and a feeding port for supplying the fresh air and a study for discharging the smoke may be provided.

When a disaster such as a fire occurs, a space on the side of the connection passage 40 outside the fire shutter 42 can be used as the evacuation safe zone 44. Hereinafter, the direction of the platform 10 will be referred to as the inside, and the direction opposite thereto, that is, the direction of the connecting passage 40, the passenger conveyance passage 30, etc., will be referred to as outside. Accordingly, the passengers of the landing platform 10 can move to the evacuation safe zone 44 within a short period of time, and can quickly evacuate using the large-capacity elevator 32 and the emergency stairs 34 in a safe state, Can be minimized.

Functional chambers can be installed in the vertical direction in the portion of the passenger conveyance passage 30 where the elevators 32 and the emergency stairs 34 are not installed.

The function room is a space for controlling electricity, a signal, and a communication facility. In most cases, the function room is planned to be a release structure together with the waiting room 20. However, in the present embodiment, the function room is not excavated separately, An economical construction is possible by utilizing the unused space of the passenger conveyance passage 30 with a large depth of view, that is, the space in which the elevator 32 is not installed. That is, in the present embodiment, a large number of spaces without the elevator 32 or the like can be formed due to the large-sized road, which can be utilized as a functional room.

The function room is divided into multiple layers from the lower side to the upper side in a portion of the passenger conveyance passage 30 where the elevator 32 or the like is not provided and the emergency stairs 34 are provided in the passenger- So that the access to the functional room can be facilitated.

In this embodiment, a special evacuation step (36) may be provided on the wall surface of the passenger conveyance passage (30) in addition to the emergency step (34) and the plurality of elevators (32).

Conventionally, in the case of constructing the great road, a special escape stairway 36 has to be provided from the underground platform 10 to the ground, which not only significantly increases construction costs, but also allows many passengers to take a special escape stairway 36 It is not easy to evacuate using the special evacuation stairs 36, and there is a problem that the special evacuation stairs 36 are difficult to serve as soot flowing into the special evacuation stairs 36 together with the passengers evacuating.

In the case of this embodiment, since the special evacuation staircase 36 is provided in the passenger conveyance passage 30, the construction cost for the special evacuation staircase 36 is not required and the construction cost is remarkably reduced. It is possible to quickly and safely evacuate to the ground through various evacuation methods including the emergency stairs 34, the elevator 32 and the special evacuation stairs 36 in a safe state after evacuation to the safe zone 44 .

Referring to FIG. 2, the passenger conveyance passage 30 may be installed on both sides of the landing platform 10. In other words, the passenger conveyance passage 30 can be provided on both sides of the landing platform 10, and the emergency stairs 34, the plurality of elevators 32, and the special evacuation stairs 36 can be installed in the passenger conveyance passage 30.

When the passenger conveyance passage 30 is installed on both sides of the landing platform 10 as described above, the connecting passage 40 connecting the landing platform 10 and the passenger conveyance passage 30 can be installed at the same height as the landing platform 10 have. In this case, the length of the connecting passage 40 is minimized, the width of the connecting passage 40 is made wider, and the width of the passenger conveyance passage 30 is also widened so that passengers can get on and off quickly and conveniently, To the zone 44.

Further, it is possible to provide an emergency door capable of directly entering the special evacuation step (36) without going through the fire shutter (42) in the landing area (10). In this case, when a fire or the like occurs, the passenger can directly enter the special escape stairway 36 through the emergency door from the landing door 10, so that passengers who have not yet evacuated even after the fire shutter 42 descends, You can escape through.

In addition, the entirety of the room 46 may be provided between the special evacuation step 36 and the emergency door, and the entire room 46 may be provided with a supply port for supplying smoke and a fresh air supply port. This entire chamber 46 can safely separate the special evacuation step 36 to prevent flames and smoke from being transferred to the special evacuation step 36 when a fire occurs.

The landing platform 10 may be divided into a first zone, which is a portion in contact with the connecting passage 40, and a second zone, which is a remaining portion, and a fire shutter 42 may be provided at the separated zone. That is, by setting the relatively wide portion of the landing 10 that comes into contact with the connecting passage 40 to the first zone, setting the rest to the second zone, and then installing the fire shutter 42 at the separated place, 10 can be secured in the evacuation safe zone 44.

The passenger of the landing area 10 quickly moves to the first zone and then passes through the connecting passage 40 to the elevator 32 of the passenger conveying passage 30 or the emergency It is possible to safely evacuate by using the step 34 or the special evacuation step 36. [

In addition, the landing platform 10 may be divided into a third zone, which is in contact with the connecting passage 40, and a fourth zone, which is the opposite side, over the entire length, and a fire shutter 42 may be provided at the separated zone. That is, the landing platform 10 can be divided into a long section and the fire shutter 42 can be installed in the divided section.

The passenger of the landing platform 10 moves to the third zone in a very short time and then passes through the connecting passage 40 to the elevator 32 of the passenger conveying passage 30, The user can safely evacuate using the emergency stairs 34 or the special evacuation stairs 36.

In other words, by securing the landing 10 in which the passengers are waiting through the descent of the fire shutter 42 formed over the entire length of the landing 10 in the evacuation safe area 44 by separating the landing position from the fire generating point in the longitudinal direction, Passengers can be evacuated quickly.
