Description

TECHNICAL FIELD

The present invention belongs to the technical field of ocean traffic engineering, and particularly relates to a fabricated ocean tunnel structure with an escape device and an application method thereof.

BACKGROUND

At present, the inland traffic network is gradually improved, and traffic construction gradually focuses on the ocean, including cross-sea bridges and ocean tunnel structures. Herein, the ocean tunnel structure is located in an ocean environment, and while facing an external high-pressure oxygen-free environment, the only passage is a tunnel road. In the case of local fire, equipment configured in the ocean tunnel structure can effectively solve the problem and ensure the safety of personnel. However, in the case of sudden serious accidents such as explosion, large-scale fire and tunnel rupture, the personnel need to escape in a very short time and a very short distance before being rescued. In the existing ocean tunnel structure, the probability of personnel escape is slim.

In order to solve the above problem, there have been some researches on an emergency escape system of the ocean tunnel structure in the prior art. For example, in the Chinese invention patent entitled “Emergency Escape System for Fire of Ocean Tunnel Structure”, it is attempted to build a transit building to ensure the safety of the escape personnel, which can be implemented in short-distance (500-1,000 m long) tunnels, but if the tunnel is hundreds of kilometers long, it is impossible to build an ocean building every one kilometer and meanwhile impossible to break the ocean tunnel structure and rebuild same in terms of engineering feasibility.

The structural safety of the ocean tunnel structure is important, but the problem of escape from a disaster after an accident must also be considered. Therefore, in view of the above shortcomings of the ocean tunnel structure, the present invention provides a fabricated ocean tunnel structure with an escape device, and further discusses an application method of the fabricated ocean tunnel structure in detail.

SUMMARY

In order to solve the shortcomings in the prior art, the present invention specifically discloses a fabricated ocean tunnel structure with an escape device and an application method thereof, which can effectively solve the problem of escape of personnel in an ocean tunnel structure in various ways without affecting the integrity and functionality of the ocean tunnel structure.

The escape device includes a rescue capsule outer wall, a rescue capsule inner wall, a support, an N-shaped rotary lock switch, a rescue capsule outer wall hatch, a rescue capsule inner wall hatch, a bidirectional rotary lock switch, a rescue capsule top hatch, an observing window hole, a rescue capsule knob, a Global Positioning System (GPS) positioning device, a transverse ladder, a rescue area, a rescue equipment area and a balancing weight block. The rescue capsule outer wall is separated from the rescue capsule inner wall by a certain gap and connected thereto by means of the arranged support distributed at a specified position, the rescue capsule outer wall hatch and the rescue capsule inner wall hatch are located on both sides of the middle portion of the rescue capsule outer wall and the rescue capsule inner wall and connected by means of the N-shaped rotary lock switch, the N-shaped rotary lock switch is located at the middle portion of the outer rescue capsule door and the outer rescue capsule door, the rescue capsule top hatch is located at the top of the rescue capsule, the bidirectional rotary lock switch is located at the middle portion of the rescue capsule top hatch, and can rotate inside and outside the rescue capsule to open or close the rescue capsule top hatch, the observing window hole is located on the periphery of the rescue capsule top hatch, the rescue capsule knob is located at the edge of the rescue capsule top hatch so that the rescue capsule top hatch can rotate, the GPS positioning device is located on the upper side of the outer portion of the rescue capsule outer wall, the rescue area is located in an inner area of the rescue capsule inner wall, the transverse ladders are horizontally and evenly distributed in the rescue capsule inner wall, the balancing weight block is located at the bottommost portion of the rescue area, the rescue equipment area is located at the upper portion of the balancing weight block, and the balancing weight block and the rescue equipment area are detachable.

When the fabricated ocean tunnel structure is installed, the seal plate is rotated and opened in the tunnel direction through the seal plate knob, then the rescue capsule is hoisted into the middle bin, the N-shaped rotary lock switch is vertically and downwards connected and fixed to the first rotary lock switch by means of a buckle, and the lower portion of the N-shaped rotary lock switch contacts the pavement area. The seal plate is closed and then the installation of the rescue device is completed, then splicing installation for offshore operations is performed according to a common fabricated construction process.

In normal operation, the tunnel outer wall is in contact with the ocean environment and bears dynamic loads such as structural weight, water pressure and waves. The tunnel middle wall and the tunnel sidewall support the middle portion of the tunnel and bear part of the upper load which is transferred to the tunnel outer wall at the bottom of the tunnel. The motor equipment bin at the upper portion of the tunnel stores a device such as a wire and optical cable ventilation duct, and the top plate bears the vertical load of the device in the motor equipment bin. A vehicle runs on the pavement area in the traffic area, and there is no water flow between the primary water pipe and the secondary water pipe during normal operation. Usually, the seal plate is in a sealed state, only the partition plate and the partition door can be seen in the traffic area, and the rescue capsule is located in the partition plate.

In case of emergency escape, there are four scenarios as follows:

• • 1. the first scenario is that a detection device detects that a disaster occurs and personnel need to escape, and ground personnel check, after receiving the news, the disaster situation, determine the personnel evacuation situation and set an escape time; the partition door, the rescue capsule outer wall hatch and the rescue capsule inner wall hatch drive the N-shaped rotary lock switch to open automatically with the rotation of the first rotary lock switch, the hatches are automatically closed when the personnel are in place, and meanwhile the seal plate is opened into the tunnel by means of the seal plate knob, so that seawater pours into the middle bin;
  • 2. the second scenario is that the detection device detects that a disaster occurs and personnel need to escape, and the ground personnel fail, after receiving the news, to make a judgment in time; according to a preset escape time of the system, the partition door, the rescue capsule outer wall hatch and the rescue capsule inner wall hatch drive the N-shaped rotary lock switch to open automatically with the rotation of the first rotary lock switch, the hatches are closed manually when the personnel are in place, the seal plate is opened in linkage, and the seawater pours into the middle bin;
  • 3. the third scenario is that the detection device detects that a disaster occurs and personnel need to escape, and the ground personnel fail, after receiving the news, to make a judgment in time; and according to a preset escape time of the system, the partition door, the rescue capsule outer wall hatch and the rescue capsule inner wall hatch drive the N-shaped rotary lock switch to open automatically with the rotation of the first rotary lock switch, the hatches are automatically closed when the personnel are in place, and meanwhile the seal plate is opened into the tunnel by means of the seal plate knob, so that the seawater pours into the middle bin; and
  • 4. the fourth scenario is that the detection device fails to detect a disaster, the personnel rotate the first rotary lock switch on the partition door by themselves, the partition door, the rescue capsule outer wall hatch and the rescue capsule inner wall hatch drive, with the rotation of the first rotary lock switch, the N-shaped rotary lock switch to open, the N-shaped rotary lock switch is, after the personnel are in place, manually rotated to close the hatches, and meanwhile the seal plate is opened in linkage, so that the seawater pours into the middle bin.

There are two ways to cause the middle bin full of seawater: the first way is that the seawater downward pours from a position where the seal plate at the upper portion of the middle bin is opened, and the other way is that the seawater pours into the middle bin by means of the primary water pipe and the secondary water pipe after pouring from another middle bin, so as to ensure that the middle bin is filled with the seawater.

Then, after the buoyancy of the rescue capsule is greater than the gravity thereof, the rescue capsule floats upward, and the N-shaped rotary lock switch is vertically separated from a first rotary lock switch, thus automatically canceling the fixation of the rescue capsule; due to the function of the balancing weight block, the floating posture of the rescue capsule remains stable, and the GPS positioning device is turned on after encountering water, so that external search and rescue personnel can locate the rescue capsule in real time; and the rescue equipment area is equipped with oxidant sodium peroxide and the like, and further with food and water, which can ensure the life needs of an evacuee within a certain period of time; and

• • after the rescue capsule floats to the surface of the sea, the personnel, after determining an arrival at the surface of the sea through the observing window hole, climb the transverse ladder and rotate the bidirectional rotary lock switch to open the rescue capsule top hatch by means of the rescue capsule knob to breathe air and wait for rescue, and meanwhile a rescuer can also rotate the bidirectional rotary lock switch from the outside to open the rescue capsule top hatch for rescue.
