Subsea tunnel water inlet escape device

Abstract

The device comprises escape pipes, escape compartments and a sealing cover, the escape pipes are arranged on the two sides of the section of the pipe wall of the tunnel, the escape compartments are placed at the bottom ends of the escape pipes, cabin doors are arranged at the bottoms of the escape pipes, the escape pipes are communicated with the interior of the tunnel through the cabin doors, the bottoms of the escape pipes are communicated with a water inlet pipe, and the sealing cover is arranged at the top of the escape pipes. When water enters the tunnel, people can enter the escape compartment in the escape pipe, water in the tunnel enters the escape pipe through the water inlet pipe, the escape compartment in the escape pipe floats to the position above the escape pipe, a sealing cover unlocking device is extruded through buoyancy of the escape compartment, and the escape compartment escapes from the escape pipe and reaches the sea surface for escape.

Description

technical field [0001] The invention relates to the technical field of undersea tunnels, in particular to an escape device for underwater tunnels. Background technique [0002] The technical engineering of the construction of transportation pipelines under the seabed in straits, bays and estuaries to communicate land-to-land transportation. Subsea tunnels are generally divided into two types: subsea surface and subsea strata, and construction methods are also different. Subsea tunnels do not hinder the water Ships are sailing and are not affected by meteorological conditions such as strong winds and fog. With the increasingly mature infrastructure technology and the development of economic strength, more and more countries have begun to build submarine tunnels. Generally, submarine tunnels are difficult to be damaged and flooded, but In the face of natural disasters such as earthquakes, the undersea tunnel may also be damaged and flooded, and the flooding of the undersea tun...

AI Technical Summary

Problems solved by technology

[0002] Under the seabed of straits, bays and estuaries, traffic pipeline technical projects for communication between land and transportation are constructed. Submarine tunnels are generally divided into two types: the seabed surface and the subsea layer. The construction methods are also different. The submarine tunnel does not hinder the water surface Ship navigation is not affected by weather conditions such as strong winds and fog. With the increasing maturity of infrastructure technology and the development of economic strength, countries have begun to build more and more undersea tunnels. Generally, undersea tunnels are difficult to be damaged by water, but In the face of natural disasters such as earthquakes, the subsea tunnel may also be damaged and flooded, and the subsea tunnel will be at a catastrophic level. Because the subsea tunnel is too long, the people in the tunnel do not have enough time to escape to the tunnel entrance and exit.
