摘要： An aircraft safety lifesaving system, disclosing an aircraft body, wherein an openable safety cabin is provided at the top of the aircraft body, a deceleration device is provided in the safety cabin, and the deceleration device is capable of being ejected from the safety cabin to enable the aircraft body to decelerate and land; a damping and buffering mechanism provided at the bottom of the aircraft body, the damping and buffering mechanism is telescopically provided in the vertical direction, and the damping and buffering mechanism is capable of extending to the position below the aircraft wheel body. A safety cabin is provided at the top of the aircraft body, and a deceleration device in the safety cabin is ejected in an emergency to assist the aircraft body to decelerate; the damping and buffering mechanism extends below the wheel body, and the damping and buffering mechanism contacts with the ground first.

摘要： An underwater traffic tunnel that includes a body immersed in water, a connector, and a ventilation system. The body comprises a first cavity for providing a passage space and a second cavity located below the first cavity. The second cavity is in communication with water; the connector connects the body and the water bottom and is used to resist buoyancy, and the ventilation system is in communication with the first cavity and extends above the water surface; the body of the present invention is safely immersed in water, and a vessel can navigate freely above the body; the second cavity is in communication with water and is not easy to be overturned by seawater; the connector resists buoyancy; the ventilation system can prevent damage by external forces through deformation and movement, and an escape system can be activated in emergency situations.

摘要： An offshore floating island includes a supporting structure and an island main body. The bottom of the supporting structure is fixed at the seabed, and the island main body includes one or two or more compartment bodies; the upper part of the supporting structure is provided with a carrying part; the bottom of each compartment body is provided with a mounting part; the compartment body is of a cavity structure, and a filler is injected to the compartment body till the compartment body sinks to cause the mounting part to be in lock type clamping with the carrying part. The island main body is of a compartment-sinking type structure; the filler is poured into the compartment bodies to cause the compartment bodies to sink; the mounting parts and the carrying part cooperate to realize detachable connection between the supporting structure and the compartment bodies.

摘要： The present disclosure provides a sea tunnel, and relates to the technical field of sea-crossing bridge tunnels. The sea tunnel comprises a body; and the body has a hollow cavity extending from one end to the other end, the cavity is divided into mutually independent first cavity and second cavity by a passage pavement, the first cavity is mainly used for passing and is wholly or partly protruded out of the sea level, the second cavity is immersed in the seawater, water holes are formed in the second cavity, and the second cavity is communicated with the seawater through the water holes. When the seawater impacts one side of the body, the second cavity is immersed in the seawater, and the seawater flows into the second cavity, so the body is not easy to be flushed over by the seawater.
