Description

Technical Field

[0001] The utility model relates to the field of hydraulics, in particular to a large navigation tunnel with an escape passage which can adapt to water level fluctuations. Background Art

[0002] When a dam is built on a river, the original route is cut off. To restore navigation upstream and downstream, measures such as navigation tunnels are necessary. Large navigation tunnels often require auxiliary traffic tunnels, which connect upstream and downstream navigation structures and serve as safe escape routes.

[0003] However, the large fluctuations in reservoir water levels due to wet and dry seasons pose a challenge to the design of escape routes in large navigation tunnels. Separate escape routes are required for varying water levels. Conventional escape routes can become submerged during rising water levels or become inaccessible during falling water levels, rendering them useless for escape. Long tunnel lengths create uncertainty about the location of an accident, and large fluctuations in water levels also create uncertainty about the elevation at which an accident will occur. This places higher demands on the spatial adaptability of escape routes, as normal, rapid escape is difficult to achieve above water. Consequently, a traditional single escape route is unable to meet the demands of these complex situations. Utility Model Content

[0004] The main purpose of the utility model is to provide a large navigation tunnel with an escape passage that can adapt to water level fluctuations, hoping to effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A large navigation tunnel with an escape passage that can adapt to water level fluctuations, characterized by comprising multiple escape passages, escape connecting plank roads, multiple escape ladders, and auxiliary traffic tunnels;

[0007] The first end of the escape passage is connected to a large navigation tunnel, and the second end of the escape passage is connected to an auxiliary traffic tunnel;

[0008] The first ends of the multiple escape routes are located at different elevations;

[0009] An escape connecting plank road is provided on the side wall of the large navigation tunnel, and at least one escape ladder is provided downwards on the escape connecting plank road near the first end of each escape passage.

[0010] While adopting the above technical solutions, the present invention may also adopt or combine the following technical solutions:

[0011] As a preferred technical solution of the present invention: the escape passage is provided with at least three escape passages, namely, high, middle and low.

[0012] As a preferred technical solution of the present invention: an escape ladder is provided downwards from the escape connecting plank road at the first end of each escape passage; and three escape ladders are provided downwards from the escape connecting plank road between the first ends of two adjacent escape passages.

[0013] As an optimal technical solution of the present invention: the escape ladder is a steel structure.

[0014] As a preferred technical solution of the present invention: the escape connecting plank road is a concrete or steel structure.

[0015] The utility model provides a large-scale navigation tunnel with an escape passage that can adapt to water level fluctuations, which has the following beneficial effects: by locating the first ends of multiple escape passages at different elevations, an escape connecting plank road is provided on the side wall of the large-scale navigation tunnel, and at least one escape ladder is provided downwards on the escape connecting plank road near the first end of each escape passage. In this way, the first ends of the multiple escape passages at different elevations are connected, so that under different water level conditions, each tunnel section can escape in time through the escape ladder-escape connecting plank road-escape passage-auxiliary traffic tunnel.

[0019] The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

[0020] like Figure 1-2As shown, a large-scale navigation tunnel with an escape channel that can adapt to water level fluctuations includes a high-level escape channel 1, a middle-level escape channel 2, a low-level escape channel 3, an escape connecting plank road 4, multiple escape ladders 5, and an auxiliary traffic tunnel 6; the first ends of the high-level escape channel 1, the middle-level escape channel 2, and the low-level escape channel 3 are connected to the large-scale navigation tunnel, and the second ends are connected to the auxiliary traffic tunnel 6. The first ends of the high-level escape channel 1, the middle-level escape channel 2, and the low-level escape channel 3 are located at different elevations. An escape connecting plank road 4 is provided on the side wall of the large-scale navigation tunnel, and at least one escape ladder 5 is provided downward on the escape connecting plank road 4 near the first ends of the high-level escape channel 1, the middle-level escape channel 2, and the low-level escape channel 3.

[0021] There are three escape ladders 5 provided downwards on the escape connecting planks at the first ends of the high-rise escape passage 1, the middle-rise escape passage 2, and the low-rise escape passage 3. There are three escape ladders 5 provided downwards on the escape connecting planks 4 between the first end of the high-rise escape passage 1 and the first end of the middle-rise escape passage 2, and between the first end of the middle-rise escape passage 2 and the first end of the low-rise escape passage 3, for a total of six escape ladders 5. A total of nine escape ladders 5 are provided.

[0022] The escape ladder 5 is a steel structure.

[0023] The escape connecting plank road 4 is a concrete or steel structure.

[0024] The number of layers of escape channels can be adjusted according to the water level, and the spacing and number of escape channels can be adjusted according to the length of the hole.

[0025] Specifically, the large-scale navigation tunnel with an escape passage that can adapt to water level fluctuations is implemented in the following manner:

[0026] When the water level is high and people need to escape, they climb the escape ladder 5 between the high-level escape passage 1 and the middle-level escape passage 2 to the escape connecting plank road 4, and escape through the high-level escape passage 1 to the auxiliary traffic tunnel 6 to complete their escape;

[0027] When the water level is medium and people need to escape, they climb the escape ladder 5 between the middle escape passage 2 and the lower escape passage 3 to the escape connecting plank road 4, escape through the middle escape passage 2 to the auxiliary traffic tunnel 6 to complete their escape;

[0028] When the water level is low and people need to escape, the escaping people climb up the escape ladder 5 at the low-level escape passage 3 to the escape connecting plank road 4, and escape through the low-level escape passage 3 to the auxiliary traffic tunnel 6 to complete the escape.
