Problems solved by technology

[0003] However, due to the differences in sea conditions and seabeds, modern sea-crossing bridges have never been able to establish a relatively unified design scheme, which brings about a fatal problem: each bridge may not be applicable due to empirical or theoretical methods. , and during the construction process may also encounter problems that have not been considered in the design stage, resulting in extended construction period and high cost
[0004] At the same time, the cross-sea bridge is designed directly according to the design life during the design period. There are many safety hazards during the operation period, and the longer the time, the worse the safety. In addition, the traditional highway and bridge system has a very long construction period, and the difficulty of the project and the total investment are huge. of
Using the method of building a subsea tunnel, the project cost is at least twice that of a cross-sea bridge, and the period is longer. The geological conditions of the subsea tunnel are complex and changeable, and the construction is difficult and risky, and at the same time destroys the ecological environment of the seabed

Embodiment 1

[0045] Such as Figure 1 ~ Figure 2 As shown, a kind of expressway floating on sea according to the present invention comprises a large number of suspension box bridges floating on the sea surface, the middle part of the top of the suspension box bridge is the road surface, and the two sides of the top are guardrails. A number of suspended box bridges are connected end to end in turn, so that the road surfaces of the suspended box bridges are connected to each other to form a highway connecting the two banks.

[0046] Such as figure 1 As shown, each suspension box bridge includes the following components:

[0047] A road main body 1 floating on the sea, the top of the road main body 1 is composed of highway road surface.

[0048] At least two barrier outer layers 2 float on the sea surface and are respectively placed on both sides of the road main body 1 to form a protective barrier. At the same time, the barrier outer layers 2 on both sides are fixedly connected to each ot...

Embodiment 2

[0062] The structure of the floating expressway in Embodiment 2 is the same as that in Embodiment 1, except that the anchoring system 3 also includes a side pull gravity seat 32 that limits the left and right floating of the suspended box bridge.

[0063] Such as Figure 4 and Figure 5 As shown, the side pull gravity base 32 is sunk on the seabed and placed on both sides of the balance gravity base 31 respectively, and the outer walls of the two side pull gravity bases 32 are connected by wire ropes. The side-pull gravity seat 32 is a cube made by pouring concrete in a steel mesh. When pouring concrete, some high-strength anchor bolts are evenly buried on the top of the balance gravity seat 31, so that the anchor bolts and the side tension gravity seat 32 are integrally formed.

[0064] The side pull gravity seat 32 can be provided with several according to the length of the suspended box bridge, and each side pull gravity seat 32 is respectively provided with a number of w...

Embodiment 3

[0068] A kind of expressway floating on the sea in this embodiment 3, its structure is the same as that of embodiment 1, the difference is that the opposite inner sidewalls of the two barrier outer layers 2 are respectively arranged as a slope, and the barrier between the outer layers 2 The distance between them decreases gradually from top to bottom.

[0069] Such as Figure 6 As shown, the cross-section of the barrier outer layer 2 is a right-angled trapezoid, and its inner sidewall is an inclined slope 24 . The inner sidewalls of the two barrier outer layers 2 are arranged opposite to each other, so that the distance between the two barrier outer layers 2 gradually decreases from top to bottom until reaching the connecting column 23 at the bottom. The inner wall of the U-shaped groove formed by the two barrier outer layers 2 is V-shaped. The reason for this arrangement is that when the floating body 12 collapses, the bridge deck 11 loses buoyancy, and the bridge deck 11 is...

Abstract

The invention discloses an expressway floating on the sea. The expressway is formed by sequentially connecting a plurality of suspension box bridges end to end. Each suspension box bridge comprises anexpressway body, insulating outer layers and an anchoring system, wherein the expressway body comprises a bridge surface and a floating body for providing buoyancy for the bridge surface, the insulating outer layers float on the sea surface, are arranged on the two sides of the expressway body respectively so as to clamp and limit the floating body and the bridge surface, the two insulating outerlayers are fixedly connected with each other, the anchoring system comprises a balanced gravity base sinking in the seabed, the balanced gravity base is provided with a plurality of steel wire ropeswhich are connected with the two insulating outer layers respectively, and the steel wire ropes are tightened so as to limit the vertical floating of the insulating outer layers. The suspension box bridges are high in design safety coefficient and long in service life; since each suspension box bridge is an independent unit, the suspension box bridges are easy to maintain and recyclable.

Description

technical field [0001] The invention belongs to the technical field of marine highways, and in particular relates to a highway floating on the sea. Background technique [0002] At present, cross-sea traffic on both sides of the sea mainly relies on shipping, shipping, and the construction of cross-sea bridges or undersea tunnels to realize transportation across the sea. However, air transportation has a limited volume and high cost; shipping has a long waiting time and sailing time, and the time cost is high; making it difficult for the two to become the main mode of transportation. Therefore, cross-sea bridges and subsea tunnels have become the main traffic structures. And as the technology of sea-crossing bridges matures day by day, the construction and use of submarine bridges have a very important contribution to the economic development of various places. [0003] However, due to the differences in sea conditions and seabeds, modern sea-crossing bridges have never be...
