Problems solved by technology

In the existing conceptual design of the Archimedes Bridge, the safety escape facilities are all considered inside the bridge body, mainly to set up safety passages on both sides of the shell wall of the bridge body. When the Archimedes Bridge encounters an accidental safety accident, the bridge body The internal safe passage is not safe, and it takes a long time to escape through the safe passage, which reduces the success rate of escape

Embodiment Construction

[0013] In Fig. 1, the bridge body 1 of the Archimedes Bridge is fixed at the bottom of the water area by tension legs 2, and four escape cabins 3 are arranged on both sides of the bridge body, and the top of each escape cabin 3 is provided with a waterproof safety exit 6, According to the length of bridge body and traffic flow, also can according to actual needs, set and adjust the quantity of escape cabin 3 accordingly.

[0014] It can be seen from Figure 2-4 that the Archimedes Bridge is located at a certain depth below the water surface 10, and the roadbed 9 inside the Archimedes Bridge body is paved with a road surface 8 for vehicles and pedestrians to pass through, and the bridge body 1 is provided with Emergency safety door 7, the bottom of emergency safety door 7 is slightly higher than road surface 8. An escape cabin 3 is arranged on the outside of the bridge body 1 corresponding to the emergency safety door 7, and the escape cabin 3 is movably connected with the bridg...

Abstract

The present invention discloses one kind of safety escape apparatus for Archimedes bridge including sealed escape compartment on Archimedes bridge body, connector between the escape compartment and the bridge body, and bridge safety door. The escape compartment is provided with waterproof safety door communicated to the bridge body, and has buoyancy slightly greater than the total weight of the escape compartment and several escape persons. The escape compartment may be separated from Archimedes bridge, and in case of accident, the persons in the Archimedes bridge can enter the nearby escape compartment to depart from the Archimedes bridge and the dangerous area.

Description

technical field [0001] The invention relates to an escape device, in particular to a safe escape device for the Archimedes bridge. Background technique [0002] The underwater floating tunnel, that is, the tunnel suspended under the water surface, also known as the Archimedes bridge, is a new concept of transportation across waters. The floating tunnel uses buoyancy to support the weight of the tunnel and the traffic load. For areas where the span of the water area is too large or the geological instability is not suitable for building bridges and underwater tunnels, or areas with environmental protection requirements, the Archimedes bridge is an ideal way to connect across water areas. At present, no Archimedes bridge has been built in the world. In addition to technical and social reasons, an important reason is the safety of the Archimedes bridge. As an underwater transportation facility, the Archimedes Bridge encounters accidents, such as water entering the bridge body ...
