Description

Technical Field

[0001] The invention relates to the field of hydraulics, and in particular to a large navigation tunnel with an escape passage capable of adapting to water level fluctuations. Background Art

[0002] After the dam is built in the river, the original route is cut off. In order to restore the navigation of the upstream and downstream, measures such as navigation tunnels are needed. Large navigation tunnels usually need to be equipped with auxiliary traffic tunnels, which connect the navigation buildings upstream and downstream and assume the function of safe escape.

[0003] However, the water level of the reservoir is affected by the flood and dry seasons and has a large fluctuation range, which brings challenges to the design of escape channels for large navigation tunnels. Under different water level conditions, escape channels need to be set up separately. Ordinary escape channels may be submerged when the water level rises or become inaccessible when the water level drops during the water level change process, thus losing their escape function. If the tunnel is long, there will be uncertainty about the location where the accident occurred; at the same time, if the water level fluctuation range is large, there will also be uncertainty about the elevation where the accident occurred. This puts higher requirements on the spatial adaptability of the escape channel, because it is difficult to achieve normal and rapid escape on the water surface. Therefore, the traditional single escape channel will not be able to meet the needs of these complex situations. Summary of the invention

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

[0005] To achieve the above object, the present invention adopts the following technical solution:

[0009] An escape connection plank road is arranged on the side wall of the large navigation tunnel, and at least one escape ladder is arranged downward on the escape connection 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 downwardly on the escape connecting plank road at the first end of each escape passage; and three escape ladders are provided downwardly on the escape connecting plank road between the first ends of two adjacent escape passages.

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

[0020] like Figure 1-2 As shown, a large-scale navigation tunnel with an escape passage that can adapt to water level fluctuations includes a high-level escape passage 1, a middle-level escape passage 2, a low-level escape passage 3, an escape connection plank road 4, a plurality of escape ladders 5, and an auxiliary traffic tunnel 6; the first ends of the high-level escape passage 1, the middle-level escape passage 2, and the low-level escape passage 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 passage 1, the middle-level escape passage 2, and the low-level escape passage 3 are located at different elevations, an escape connection 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 connection plank road 4 near the first ends of the high-level escape passage 1, the middle-level escape passage 2, and the low-level escape passage 3.

[0021] 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 are provided with an escape ladder 5 downward, for a total of three.
