Description

Waterproof escape passage for tunnel

Technical Field

The invention relates to the field of tunnel escape, in particular to a waterproof escape channel for a tunnel.

Background

The tunnel is a channel dug in an existing building or an earth-rock structure, and is an engineering building buried in the ground. Generally, the tunnel is relatively closed and long, so that the people suffering from a disaster can be evacuated to a safe place through the escape passage when encountering accidents such as fire, flood and the like. Rescue workers can also enter the accident scene through the escape passage.

The tunnel facilitates traffic of people, effectively relieves traffic jam on the ground, and saves ground space. At present, the existing underground tunnels in China have relatively perfect emergency measures in the aspects of fire prevention and toxicity prevention, but are all deficient in the aspects of water prevention and flood control.

In the emergency situation that the existing tunnel is subjected to short-time heavy rainfall or the tunnel at the bottom of a river or a lake at the bottom of the sea is cracked, the water accumulation speed in the tunnel is high, and people suffering from disasters often difficultly escape from the tunnel through a safety channel independently. Rescue workers are often difficult to rescue, and generally a pipeline water pumping mode is used, so that the time consumption is long, and the rescue success rate is low.

Disclosure of Invention

The invention aims to provide a waterproof escape channel for a tunnel, which can provide oxygen for people suffering from a disaster and rescue workers and meanwhile, the people suffering from the disaster can independently escape from the tunnel.

In order to solve the technical problems, the invention adopts the technical scheme that: a waterproof escape passage for a tunnel.

Escape passage doors are arranged on two sides of the tunnel at intervals, and the escape passage doors are directly connected with the waterproof escape passage. Two ends of the waterproof escape passage are directly communicated with the outside land or are communicated with the outside through a vertical shaft. An air inlet pipe 1 is arranged at the top of the escape passage. Sealing partitions 3 are arranged above the top of the channel at intervals, air inlet valves 2 are arranged between the partitions, and the air inlet valves 2 are connected with the air inlet pipe 1. The left side and the right side of the waterproof escape passage are respectively provided with 5, 6 and 7 handrails, and each row of handrails are separated by a certain distance. The handrail is used for being convenient for personnel to grasp when the passageway produces ponding.

Furthermore, when strong rainfall such as typhoon occurs, the water level in the tunnel rises sharply, and the people suffering from disasters in the tunnel can run to the waterproof escape door immediately and can be in an open state all the time after being opened, so that the people suffering from disasters can enter the escape door subsequently.

Furthermore, the air inlet pipes are divided into a plurality of groups, the water level in the tunnel rises sharply, and an inflating pump is arranged outside the tunnel and used for pressing and sending the outside air to each air inlet through the plurality of groups of air inlet pipes. So as to ensure that each air inlet provides enough air for the closed space with the downward opening formed by the partition.

Compared with the prior art, the invention has the advantages and positive effects that:

1. the invention has simple structure, and the design of the air inlet valve and the sealing partition can ensure that the air still exists above the channel even if the tunnel is completely flooded by the disaster-stricken personnel. The air can be provided when the disaster-stricken person independently flees, and the disaster-stricken person with inconvenient action can stay in the original place to wait for rescue.

2. The invention can ensure that the escape door is always in an open state, ensures the escape opportunity of people in a disaster who evacuate from the tunnel slowly, and solves the problem that the escape door is difficult to open when the water level is higher than the escape door.

The design of the multilayer handrail can lead the disaster-stricken person to automatically adjust the gripping height according to the current water level height, and plays a role in assisting escape for the old, women and children without swimming.

Detailed Description

The following are specific embodiments of the present invention and are further described with reference to the drawings, but the present invention is not limited to these embodiments.

When the tunnel breaks in the weather of typhoon, strong rainfall and the like or at the bottom of the sea, river or lake, the water level in the tunnel rises sharply. The tunnel is accessible by persons in the tunnel as shown in figure 1. Two ends of the waterproof escape passage are directly communicated with the outside land or communicated with the outside through a vertical shaft. An air inlet pipe 1 is arranged at the top of the escape passage. Sealing partitions 3 are arranged above the top of the channel at intervals, air inlet valves 2 are arranged between the partitions, and the air inlet valves 2 are connected with the air inlet pipe 1. The left side and the right side of the escape passage are respectively provided with a handrail 5, a handrail 6 and a handrail 7, and each row of handrails are separated by a certain distance. The handrail is used for being convenient for personnel to grasp when the passageway produces ponding.

When the water level in the escape passage 9 rises, the evacuee can float upwards to grasp the handrail at a higher layer to assist the evacuee.

When the water level is higher than the sealing partition, the space is sealed by water and the sealing partition to form a plurality of closed spaces 10, and the air inlet valve 2 continuously conveys fresh air to the closed spaces 10, so that the rising height of the water level is small, and enough space above the channel is provided for the escape personnel to breathe. And can maintain breath for a long time. The escape personnel independently enter the next closed space from one closed space until the escape passage.

The embodiments of the present invention have been described in detail, but the description is only for the preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. The tunnel itself can adopt the principle of the invention, and the similar partition and the air inlet valve are made on the top of the tunnel to form a waterproof channel when the tunnel is flooded with water. Meanwhile, a sealed high-pressure oxygen cylinder is arranged at the top of the channel, and oxygen is supplied to escape personnel under the condition of tunnel collapse and other damage conditions within the coverage range of the patent. All equivalent changes and modifications made within the scope of the present invention should be considered within the scope of the present patent.

Although the terms intake pipe 1, intake valve 2, seal partition 3, passageway top 4, handrail 5, handrail 6, handrail 7, passageway pavement 8, escape route 9 and enclosed space 10 are used more often herein, the possibility of using other terms is not excluded. These terms are used merely to more conveniently describe and explain the nature of the present invention; they are to be construed as being without limitation to any additional limitations that may be imposed by the spirit of the present invention.
