Description

Technical Field

[0001] The invention relates to the field of bridges, and in particular to a controlled floating sea-crossing bridge. Background Art

[0002] Existing cross-sea bridges are mostly built with reinforced concrete, which are large in size, heavy in weight, and have a large wind resistance coefficient. They can neither adapt to the complex geological conditions of the seabed nor to the natural environment such as strong winds and waves on the sea surface. They require a large amount of work, high construction costs, and a long construction period. Summary of the invention

[0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a bridge foundation that avoids complex geological conditions such as deep seabed, trenches, earthquakes, etc., and improves the ability of the bridge body on the sea surface to resist strong winds and waves, and is not affected by the sea depth within a certain range. The bridge body does not require concrete. The main materials used are steel pipes, towers, pillars, and flat beams. It is a controlled floating cross-sea bridge with the advantages of high strength, small volume, and low wind resistance coefficient.

[0004] The device includes a buoyancy control weight, which has a counterweight and is set at the seabed level when in use; The buoyancy control weight is connected with a buoyancy box via a buoyancy control pull rod; A tower column is arranged on the pontoon, a road surface flat beam is arranged on the tower column, and a plurality of inclined tie rods are arranged in an array between the road surface flat beam and the tower column.

[0005] The effect achieved in this way is that the buoyant weight sinks to the seabed level, and the pontoon is controlled to be below the sea surface by the buoyant control rod. The tower column on its upper part serves as a supporting member to support the pavement flat beam, and a plurality of inclined rods are arranged between the pavement flat beam and the tower column to pull the pavement flat beam, so that the pavement flat beam can be used as a direct support for the means of passage for the passage of vehicles.

[0006] The beneficial effects of the present invention are as follows: the present invention solves the problems of deep sea, complex seabed geological conditions, strong winds and waves on the sea surface, etc. of cross-sea bridges, and reduces and shortens the cost and construction period of bridge construction. It can greatly shorten the construction period and construction cost; and because the present invention has advanced design and reliable anti-corrosion technology, the operation time is not less than 100 years. It is applicable to many coastal straits, bays, and offshore islands, and has huge economic and social benefits. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0008] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The floating cross-sea bridge of the present invention comprises a floating weight body 9, wherein the floating weight body 9 has a counterweight and has sufficient weight. When in use, the floating weight body 9 is arranged on the seabed level 11; The buoyancy control weight 9 is connected with a buoyancy box 5 via a buoyancy control pull rod 7; The pontoon 5 is provided with a tower column 1, and a road surface beam 20 is provided on the tower column 1. A plurality of inclined rods 21 are arranged in an array between the road surface beam 20 and the tower column 1, so as to ensure the stability of the bridge body.

[0009] The effect achieved in this way is that the buoyancy-controlled weight 9 sinks to the seabed level 11, and the pontoon 5 is controlled below the sea level by the buoyancy-controlled pull rod 7. The tower column 1 on the top serves as a support member to support the pavement beam 20, and a plurality of inclined pull rods 21 are arranged between the pavement beam 20 and the tower column 1 for pulling the pavement beam 20, so that the pavement beam 20 can be used as a direct support for the means of transportation for the passage of the means of transportation.

[0010] Furthermore, each buoyancy box 5 is equipped with at least three buoyancy control weights 9 , which are arranged at intervals and connected to the buoyancy box 5 via a buoyancy control rod 7 .

[0011] Preferably, the buoyancy tank 5 is arranged at a position 6-7 meters below the sea level.

[0012] The effect achieved in this way is that the location is less affected by the waves and is not constrained by the complex geological conditions of the seabed. The structure is simplified, there are no changes in bridges, islands, and tunnels, and there are no unforeseen projects. Relevant components can use standard parts to facilitate quantitative production. Construction is only an "assembly" process, which greatly shortens the construction period and significantly reduces the cost.

[0013] In this way, the weight support structure of the bridge is not located at a great depth or under complex geological conditions, but on a pontoon 6-7 meters below the sea surface that is not affected by wind and waves. The pontoon is connected to the buoyancy control weight that is sunk to the seabed through a tie rod; Preferably, each buoyancy control weight 9 is connected to the buoyancy box 5 via at least four buoyancy control rods 7 .

[0014] The effect achieved by this is to ensure the stability of the buoyancy box 5.

[0024] Preferably, a power line rack 14 , a steel rail 15 and an I-beam 16 are also provided on the road surface flat beam 20 .

[0025] The effect achieved by this is that more vehicles such as trains, trams, etc. can pass on the road surface beam 20.

The outside is wrapped with double-sided glass cloth coated with tung oil, no less than two layers, one layer on the left and one layer on the right. In addition to coating the inside and outside of the pontoon 5, the metal parts need to be filled with inert gas before closing. The tie rod joint 8, dead corners and cracks are filled with water-resistant grease (such as sodium-based grease), and the outside is wrapped with glass cloth. The terminal is tied with stainless steel wire and coated with tung oil again.

[0032] Preferably, monitoring rooms are provided at both ends of the bridge to display changes in the air pressure in the pontoon 5 and abnormal phenomena in other parts of the bridge body in a timely manner so as to facilitate response.
