Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without any inventive step, are within the scope of the present invention.

The invention provides a marine traffic tunnel, and the technical scheme provided by the invention is explained in more detail with reference to fig. 1 to 3.

As shown in fig. 1 to 2, the marine traffic tunnel according to the embodiment of the present invention is mainly built between two coasts. The tunnel comprises a tunnel body 1, wherein the shape of the body is not limited, and the body can be a cuboid, an irregular polygon and the like. Preferably, the body is cylindrical, which facilitates the manufacturing process and reduces the impact force against the seawater.

Tunnel body 1 has the cavity that extends from one end to the other end, and the cavity is split into mutually independent first cavity 4 and second cavity 5 by current road surface 10, is provided with beacon 2 rather than the intercommunication on first cavity 4, and beacon 2 height stands out the sea, can provide mobile air for first cavity 4, and second cavity 5 is equipped with rivers hole 501, and rivers hole 501 makes second cavity 5 and sea water intercommunication, and tunnel body 1 passes through stock 3 and is connected with the bottom of the sea.

The second chamber 5 is provided with a water flow hole 501, and the water flow hole 501 enables the second chamber 5 to be communicated with the seawater. In other words, seawater may enter the second chamber 5 as part of the second chamber 5. When the seawater impacts one side of the body, the body is not easy to be overturned by the seawater because the second cavity 5 is immersed in the seawater and the seawater flows into the second cavity 5. Secondly, the bottom end of the body is connected with the bottom of the sea through an anchor rod 3. At this moment, because the second cavity 5 is immersed in the seawater, the anchor rod 3 only resists the buoyancy of the body, and compared with the traditional bridge, the anchor rod 3 can not provide supporting force for the body, so that the structure of the whole body is very stable and firm. In this embodiment, three anchor rods 3 are simultaneously arranged in the width direction of the body, so that the stability of the body is ensured.

It is emphasized that the bottom end of the anchor rod 3 connected to the sea bottom in this embodiment is provided with a spring to allow a certain play space for the anchor rod 3 for resetting. Meanwhile, the spring coefficient of the spring is large, the spring cannot be stretched or compressed randomly under general conditions, and the spring can be stretched or compressed only when large acting force is met.

Further, still be equipped with the bridge frame at the body along length direction's both ends to improve the stability of body, the bridge frame adopts reinforced concrete to support, preferably, can set up a bridge frame every 1 ~ 1.5km along body length direction. Furthermore, each bridge bracket is provided with a spring ring to play a role in shock absorption.

Preferably, the bottom end of the second cavity 5 is further provided with a weight layer 14, the weight layer 14 mainly enables materials with higher density (such as filling and attaching corrosion-resistant steel plates) to be directly arranged at the bottom end of the second cavity 5, and the advantage of such arrangement is that, by using the weight layer 14, the center of gravity of the whole body can move downwards, so that the body is more stable and is not easy to topple over.

Further, the second cavity 5 is symmetrically arranged with the vertical axis of the body as the symmetry axis, and the two side walls of the symmetry axis of the second cavity 5 are provided with water flow holes 501, at this time, the seawater can flow into the second cavity 5 from the two sides of the second cavity 5 at the same time. Preferably, the water flow holes 501 are provided above the second chamber 5, which enables the seawater to more easily flood the entire second chamber 5 than if the water flow holes 501 were provided below the second chamber 5. In the present embodiment, the number of the water flow holes 501 is not limited.

In this embodiment, the body is provided with a housing. The outer wall 6 of the housing is formed by a double-layered solid structure, i.e. there is no gap between the double-layered solid structure. The water flow holes 501 pass through the double-layer solid structure and communicate the second cavity 5 and the seawater. Because the shell adopts a double-layer structure, the safety and the stability of the body can be ensured. When the outer layer structure is damaged, the inner layer structure can still be used and kept in balance.

In the preferred embodiment of the present embodiment, the first chamber 4 is formed by an outer wall 6 and an inner wall 7 which are spaced apart. It should be noted that the first chamber 4 and the second chamber 5 share a double-layer outer wall 6. Since the first chamber 4 is a passage space, the first chamber 4 is further provided with an inner wall 7 in order to improve the safety of the passage space. A plurality of stabilizing mechanisms along the body passing direction (or the body length direction) are arranged between the outer wall 6 and the inner wall 7. A plurality of stable structures are arranged at intervals. The securing mechanism includes a guide rail 8 provided in the width direction of the body. Specifically, when the passing road surface 10 is provided in the middle (on one diameter) of the body, the cross section of the guide rail 8 is in a semicircular arc shape.

A plurality of pulleys 9 are arranged in the guide rail 8, and each pulley 9 is fixed in the guide rail 8 by a rotating shaft. The pulley 9 can rotate in the guide rail 8 with respect to the rotation shaft. The rotating shaft is arranged along the passing direction of the body. The pulleys 9 abut against the outer wall 6 and the inner wall 7, respectively. That is, after the inner wall 7 is fixed, when the outer wall 6 rotates under the action of seawater, the pulley 9 can disperse the rotating action of the outer wall 6, so that the inner wall 7 is not affected by the outer wall 6, and the stability of the passing space in the whole first cavity 4 is ensured. Preferably, a plurality of pulleys 9 are uniformly provided in the guide rail 8.

In this embodiment, the outer wall of the body is made of high-resin fibers, and the inner wall of the body is made of high-strength steel, and the high-resin fibers and the steel can not only resist corrosion, but also ensure the strength of the body.

And pipe wall expansion joints are further arranged along the passing direction of the bodies, and the plurality of bodies can be quickly and stably connected together by utilizing the pipe wall expansion joints.

Preferably, the number of the car passing areas 12 is 2, and the car passing areas are respectively located on both sides of the high-speed rail passing area 11. It should be noted that each vehicle passing area 12 may be a single lane or a multi-lane. Further, the high-speed rail passing region 11 is an independent tunnel. Preferably, in order to accelerate the high-speed rail, the high-speed rail passing area 11 can be sealed, vacuum is pumped, air resistance is reduced, and vacuum acceleration is adopted.

Still be equipped with overpass 13 in the first cavity 4, the bottom and the road surface 10 of passing through of overpass 13 are connected through first support column, and the top of overpass 13 is connected through the top of second support column and body. Preferably, the number of the viaducts 13 is 2, and the viaducts 13 correspond to the vehicle passing areas 12 one to one. Meanwhile, each viaduct 13 may be a single-lane or a multi-lane.

As shown in fig. 3, the structure of the gateway of the marine traffic tunnel is schematically illustrated, and the tunnel comprises a land-based section 15, a gateway transition section 16 and a sea-based section 17, and the tunnel is slowly descended to a predetermined depth with a slope.

Preferably, a solar system capable of providing illumination for the first cavity 4 and a ventilation system capable of ventilating the first cavity 4 are arranged in the lighthouse 2. The tower column of the lighthouse 2 is in a curve shape capable of reducing fluid resistance, the lighthouse 2 is at least 15m higher than the sea surface, warning buoys are arranged on the sea surface and under the sea surface around the lighthouse 2, and the warning buoys surround the lighthouse and can form a safety warning area. The safety warning area is oval or circular, preferably circular, and the radius of the safety warning area is set to be at least 1000 m. The warning buoy is provided with a light and electronic induction system and provides a channel for ships and submarines to pay attention to.

Further, the interval between the lighthouses 2 is larger than 3km, an automatic closing valve capable of preventing seawater from flowing backwards is arranged between the lighthouses 2 and the first cavity 4, and once an accident is detected, automatic closing is carried out.
