[0029] The features and performance of the subway tunnel escape passage of this application will be further described in detail below with reference to the embodiments.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown in the figure, this application embodiment provides a subway tunnel escape passage for helping passengers escape from two parallel and spaced subway tunnels 100. The subway tunnel escape passage includes an outer tunnel escape passage 110 extending along the length of the subway tunnel 100. An escape handrail 111 is provided inside the outer tunnel escape passage 110. The outer tunnel escape passage 110 is located between the two subway tunnels 100 and one end connects to an adjacent subway platform. The other end of the outer tunnel escape passage 110 is connected to two downward-extending inclined staircase passages 120 on each side. The bottom of the two inclined staircase passages 120... The lateral transfer passage 200 connects to two subway tunnels 100. Each subway tunnel 100 has an escape hatch 121 on its side wall that connects to the lateral transfer passage 200. The inner wall of the subway tunnel 100 is also connected to a water-blocking arc-shaped door 130 that fits against the inner wall. The water-blocking arc-shaped door 130 is configured to be able to slide along the length of the subway tunnel 100 to align with or detach from the escape hatch 121. When aligning with the escape hatch 121, it can also slide along the width of the subway tunnel 100 to close or open the escape hatch 121. The net width of the lateral transfer passage 200 is more than 1000mm and the net height is more than 2200mm.

[0031] The subway tunnel 100 has tracks 140 extending along its length on its inner wall above and below. Each track 140 has a first chute 150 extending along its length and two second chute 160 extending along its width. The second chute 160 connects to the corresponding second chute 160 of the first chute 150. The top and bottom of the water-blocking arc-shaped door 130 are connected to two rotatable spherical pulleys 170 via pulley seats 171. The distance between the two pulleys 170 is equal to the distance between the two corresponding second slide grooves 160. When the water-blocking arc door 130 moves along the length of the subway tunnel 100, each pulley 170 moves along the corresponding first slide groove 150. When the water-blocking arc door 130 is aligned with the escape opening 121, it moves along the pulleys 170 to the point where the corresponding first slide groove 150 and second slide groove 160 connect. When the water-blocking arc door 130 moves along the width of the subway tunnel 100, each pulley 170 moves along the corresponding second slide groove 160. The water-blocking arc-shaped door 130 is connected to a handle 181. The handle 181 and the water-blocking arc-shaped door 130 form a locking groove 180. The inner wall of the subway tunnel 100 is also connected to a locking block 190 that can move along its length. When the water-blocking arc-shaped door 130 closes the escape opening 121, the locking block 190 moves along the length of the subway tunnel 100 and inserts into or disengages from the locking groove 180 to lock or unlock the water-blocking arc-shaped door 130 as it moves along the width of the subway tunnel 100.

[0032] The inner wall of the subway tunnel 100 is also provided with a rail-side transfer platform 210 extending along its length and support plates 211 arranged at intervals. The distance between the rail-side transfer platform 210 and the subway car inside the subway tunnel 100 is 70mm. The width of the rail-side transfer platform 210 is more than 1000mm. The support plates 211 are connected to the inner wall of the subway tunnel 100 and the bottom wall of the rail-side transfer platform 210 respectively. The top wall of the rail-side transfer platform 210 is at the same height as the bottom wall of the subway car inside the subway tunnel 100. The rail-side transfer platform 210 is connected with support rods 220 arranged at intervals along its length. Each support rod 220 has a limit rod 230 that can rotate along the vertical plane hinged on both sides of its top. The inner wall of the subway tunnel 100 is also provided with fixed handrails 240 arranged at intervals along its length. The top heights of the fixed handrails 240 and the support rods 220 are the same. Three fans 250 are installed in the escape passage 110 outside the tunnel; the support rod 220 is 1200mm long and the limiting rod 230 is 600mm long; the limiting rod 230 can rotate within a 90-degree angle between horizontal and vertical orientation; the fixed handrail 240 is 1490mm long and 20mm in diameter, and both ends and the middle of the fixed handrail 240 are fixed to the inner wall of the subway tunnel 100, and the distance between adjacent fixed handrails 240 is 140mm.

[0033] The subway tunnel escape passage provided in this embodiment can help passengers escape from the subway tunnel 100. When the subway stops for any reason, after opening the subway car door, the subway passenger can push the limit rods 230 hinged on both sides of the top of the support rod 220 connected to the side wall of the rail-side transfer platform 210 to rotate along the vertical plane and stop blocking, thus climbing onto the rail-side transfer platform 210 at the same height as the bottom wall of the subway car. Then, the passenger can hold onto the fixed handrail 240 set on the inner wall of the subway tunnel 100 and move to the escape opening 121 and the water-blocking arc door 130 on the inner wall of the subway tunnel 100. By moving the locking block 190 along the length direction of the water-blocking arc door 130, the locking block 190... Once the water-blocking arc-shaped door 130 is disengaged from the locking groove 180 and stopped, passengers can hold the handle 181 connected to the water-blocking arc-shaped door 130 and pull it to move it horizontally along the width of the subway tunnel 100. This causes the two pulleys 170 connected to the top and bottom of the water-blocking arc-shaped door 130 to move along the corresponding second slide groove 160 into the first slide groove 150. Then, the water-blocking arc-shaped door 130 is pushed to move along the length of the subway tunnel 100 to the escape hatch 121 that is detached from the inner wall of the subway tunnel 100. Passengers can then enter the lateral transfer passage 200 through the escape hatch 121 and move to the nearest subway platform via the inclined stair passage 120 and the outer tunnel escape passage 110.

[0034] The support rods 220 connected to the side wall of the rail-side transfer platform 210 are hinged on both sides of their tops, with limiting rods 230 that can rotate along the vertical plane. This ensures the safety and orderliness of the escape process. The limiting rods 230 ensure the safety of longitudinal evacuation of passengers, preventing passengers from sliding towards the rail side of the platform due to overcrowding. They also assist passengers in walking steadily when the water flow is strong in the subway tunnel 100, and facilitate the transfer of passengers to the rail-side transfer platform 210 when the train stops. The fixed handrails 240 installed on the inner wall of the subway tunnel 100 and the escape handrails 111 installed in the escape passage 110 on the outside of the tunnel help elderly and weak passengers stabilize their bodies when escaping. In the case of strong water flow, passengers can use the fixed handrails 240 and the limiting rods 230 together to ensure walking safety. The gaps in the fixed handrails 240 can separate the flow of people and prevent overcrowding.

[0035] In addition, after all passengers have escaped to the lateral transfer passage 200, the water-blocking arc-shaped door 130 can be moved sequentially along the length and width of the subway tunnel 100 to re-close the escape exit 121. This prevents water accumulated in the subway tunnel 100 from flowing into the lateral transfer passage 200 through the escape exit 121 and endangering the lives of those escaping. It also reduces the risk of passengers escaping outside the tunnel due to backflow of water. In cases of large water flow, the horizontal movement of the water-blocking arc-shaped door 130 can reduce the resistance when opening and closing. By setting up an inclined stepped passageway 120 that is inclined to the horizontal plane to connect the upper outer tunnel escape passageway 110 and the lower lateral transfer passageway 200, the height can be raised to reduce the vertical slope of the outer tunnel escape passageway 110 and reduce discomfort during the escape process. On the other hand, it can be moved away from the subway tunnel 100 below, reducing the rate of water rise in the outer tunnel escape passageway 110 in the event of a flooding accident, thus buying time for passengers to escape. The fan 250 installed in the outer tunnel escape passageway 110 can promote air circulation and ensure the oxygen supply for passengers escaping in the outer tunnel escape passageway 110.
