Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1 and 6, the present embodiment provides a rigid-flexible combined folding floating bridge, including: a plurality of pontoon modules connected side-by-side;

each floating bridge module is detachably hinged with the adjacent floating bridge module through the corresponding flexible connector 4;

a cylindrical fixed shaft 3 extends outwards from both sides of the head end and the tail end of each floating bridge module;

each cylindrical fixed shaft 3 can abut against the cylindrical fixed shafts 3 at the same side and the opposite end of the adjacent pontoon module of the pontoon module through the flexible connectors 4.

In this embodiment, in two adjacent pontoon modules, the opposite end of the tail end of one pontoon module is the head end of the other pontoon module. Therefore, when two pontoon modules are hinged adjacent to each other, only two cylindrical stationary shafts 3 which are respectively at opposite ends of the same side can abut against each other.

The floating bridge is formed by connecting a plurality of floating bridge modules side by side, so that modularization can be realized during assembly or disassembly; and when transporting and depositing, can stack a plurality of pontoon bridge modules, significantly reduced the parking space. In addition, in the embodiment, the flexible connector 4 is used for connecting the cylindrical fixed shafts of the adjacent pontoon modules, so that the folding and the pre-connection among the pontoon modules can be realized, and the storage and transportation efficiency and the assembly operation efficiency of the pontoon can be greatly improved.

As shown in fig. 1, 4 to 5, the floating bridge module sequentially includes from top to bottom: the bridge deck 2, the air bag layer 1 and the water bag layer 5;

cylindrical fixed shafts 3 are arranged on two sides of the bridge deck 2.

In the present embodiment, for the sake of example, only the interconnection between two pontoon modules is illustrated, whereby in fig. 1, 4 to 5 only two flexible connectors 4 are used between two pontoon modules. The two cylindrical fixed shafts 3 on two sides of the tail end of one pontoon bridge module are respectively abutted against the two cylindrical fixed shafts 3 on two sides connected with the head end of the other pontoon bridge module and then connected through the corresponding flexible connectors 4.

The airbag layer 1 includes: the main airbag 1.1 and the auxiliary airbag 1.2 are arranged along the length direction of the bridge deck 2;

the auxiliary air bags 1.2 are arranged on two sides of the main air bag 1.1; both ends of the auxiliary air bag 1.2 are positioned below the corresponding bridge deck 2;

one end of the main airbag 1.1 extends to the middle part of the corresponding bridge deck 2 below one adjacent bridge deck 2, and the other end is positioned in the middle part of the corresponding bridge deck 2 below.

In the present embodiment, the airbag layer 1 is constituted by five airbags for each pontoon module, including: two auxiliary airbags 1.2 and three main airbags 1.1. The five air bags correspond to the bridge deck 2 of the same floating bridge module. Three main airbags 1.1 of the same floating bridge module share one inflation valve pipeline 7 for inflation and deflation. The inflation valve tubing 7 is located at one end of the three primary airbags 1.1. The three main airbags 1.1 share one inflation valve pipeline 7, so that the inflation efficiency is improved.

The two auxiliary air bags 1.2 are respectively arranged at two sides of the three main air bags 1.1, and one end of each auxiliary air bag 1.2 is respectively provided with a control valve 8 for inflating and deflating the auxiliary air bag 1.2. One end of each auxiliary air bag 1.2 is locally reinforced around the control valve 8 to ensure that the control valve 8 can work safely.

Taking the view angle in fig. 4 as an example, the floating bridge module located on the left side in the figure is the left floating bridge module, and the floating bridge module located on the right side in the figure is the right floating bridge module. As can be seen in fig. 4, one end of the three main airbags 1.1 of the left pontoon module extends to the left, so that the other end of the three main airbags 1.1 is located in the middle below the deck 2 of the left pontoon module. The lower part of the bridge deck 2 of the left floating bridge module is provided with a space from the right end. One end of three main air bags 1.1 of the floating bridge module on the right extends leftwards to the space below the bridge deck 2 of the floating bridge module on the left.

The main airbags 1.1 and the corresponding bridge panels 2 are arranged in a staggered mode and have the effect of resisting the force in the vertical direction of the joint of the two adjacent floating bridge modules by utilizing the longitudinal strength of the inflated airbags, so that the deformation of the joint of the floating bridge modules can be greatly reduced.

The water bag layer 5 comprises a plurality of water bags 5.1;

the outer surfaces of each main air bag 1.1, each auxiliary air bag 1.2 and each water bag 5.1 are covered with a woven net 10;

the woven net 10 is used for mutually restricting the positions of the main air bag 1.1, the auxiliary air bag 1.2 and the water bag 5.1;

the air bag layer 1 and the water bag layer 5 of the same floating bridge module are wrapped into a whole by weaving an outer net 6, so that the air bag layer 1 and the water bag layer 5 are fixed with the corresponding bridge deck 2.

In the present embodiment, the water bladder layer 5 is made up of four water bladders 5.1 for each pontoon module. The water bag layer 5 is positioned below the air bag layer 1, and each water bag 5.1 is positioned below the gap between two adjacent air bags. The structure can ensure the stability between the water bag layer 5 and the air bag layer 1, and the displacement between each air bag and the water bag 5.1 in the width direction of the bridge deck 2 is not easy to occur.

The water bag layer 5 is used for reducing the gravity center of the floating bridge and ensuring the stability of the floating bridge. The four water bags 5.1 share one water injection pipeline 9, so that water injection is facilitated. The water injection pipeline 9 is arranged at one end of each of the four water bags 5.1, so that the flushing and water discharging efficiency can be improved.

The surface of each air bag and each water bag 5.1 is covered by a woven net 10, the woven net 10 is woven by nylon flat belts, the relative positions of each air bag and each water bag 5.1 are fixed by mutually connecting the woven nets 10, and the air bags and the water bags 5.1 are prevented from moving in a dislocation way when the floating bridge is erected and recovered. The outer net 6 is woven to enable the air bag layer 1 and the water bag layer 5 to be better fixed on the corresponding bridge deck 2, so that the whole floating bridge module is more stable.

The structural form of the bag body of each air bag and each water bag 5.1 belongs to a film structure, and the air bag is sequentially made of a laminated composite material formed by pressing an anti-aging layer, an adhesive layer, a gas barrier layer, an adhesive layer, a woven load bearing layer and an adhesive layer. The material has strong tensile resistance, so that the capsule body is not easy to tear under the action of large surface tension.

As shown in fig. 2 and 3, the flexible connector 4 includes:

and the flexible connecting belt 11 is used for winding the outer sides of the curved surfaces of the two cylindrical fixed shafts 3 which are close to each other, so that the pontoon modules where the two cylindrical fixed shafts 3 which are close to each other are positioned are hinged with each other.

The pre-connection between the modules of the pontoon can be achieved by means of the flexible connecting strips 11. The flexible connecting belt 11 is only wrapped on the surfaces of the two cylindrical fixed shafts 3 which are close to each other, and the two cylindrical fixed shafts 3 can rotate mutually and cannot be separated under the action of the flexible connecting belt 11 because the cylindrical fixed shafts 3 are cylindrical, so that the effect of hinging the adjacent pontoon modules mutually is achieved.

In one embodiment, after the floating bridge modules are separated, the floating bridge modules can be folded for storage; in another embodiment, the floating bridge modules can be folded to be stored when the cylindrical fixed shafts 3 abutting against each other are wrapped by the flexible connecting band 11.

The flexible connector 4 further includes:

and the outer layer steel ring 12 is wrapped on the outer surface of the flexible connecting band 11 and used for reinforcing the connection between the two cylindrical fixed shafts 3 which are close to each other.

In the present embodiment, the flexible connector 4 is formed by combining an inner flexible connecting band 11 and an outer steel ring 12. The flexible connecting band 11 of the inner layer is made of high-strength materials, and the deformation between the outer layer steel ring 12 and the cylindrical fixing shaft 3 is reduced by utilizing the elastic deformation of the inner layer steel ring when the inner layer steel ring is extruded. The outer steel ring 12 can ensure that the connection between two adjacent pontoon modules is firmer. The flexible connector 4 realizes the pre-connection of the floating bridge on the land, when the floating bridge is built, all the floating bridge modules can be connected on the land by the flexible connecting belt 11, the rudiment of the floating bridge is built, and then the outer layer steel ring 12 is wrapped outside all the cylindrical fixed shafts 3 which are close to each other, so that the pre-connection is firmer. Therefore, the flexible connector 4 saves the step of connecting the floating bridge module in water during construction, and improves the assembling efficiency of the floating bridge. Because the friction resistance of the flexible connecting band 11 and the outer steel ring 12 is very small when the cylindrical fixed shaft 3 rotates relatively, the floating bridge can be folded through the relative rotation of the cylinder, and the storage and transportation space and the cost of the floating bridge are saved.

A lifting lug 13 is fixedly arranged on the end surface of the outer side of each cylindrical fixed shaft 3;

the lifting lugs 13 on the two cylindrical fixed shafts 3 which are close to each other are connected through a steel chain 14.

In this embodiment, each lifting lug 13 is arranged at the eccentric position of the corresponding cylindrical fixed shaft 3, so that the lifting construction is convenient. A steel chain 14 between the two lifting lugs 13 can further limit the relative rotation between the two pontoon modules after the pontoon is unfolded. Through the damping effect of flexible connection belt 11, can effectively reduce the influence of wave load, appear obviously sunken when avoiding the pontoon pressurized, strengthened the holistic reliability of pontoon, the event has stronger resistance to the shearing stress and the moment of torsion that the pontoon produced to the wave.

In this embodiment the function of the stiffeners 22 is to increase the load bearing capacity of the deck slab 2. The section of the bridge deck 2 is of a cavity structure, so that the weight of the bridge deck is reduced as much as possible while the mechanical property is ensured, and the actual laying efficiency is improved. The interior of the bridge deck 2 is of a structure similar to a ship skeleton, so that the metal material consumption is saved, and meanwhile, the sufficient strength is ensured. The inner contour 18 of the bridge deck 2 is fit with the curved surface of the air bag 1, so that the air bag 1 is better contacted and fixed with the bridge deck 2,

as can be seen from fig. 7 and 10, below the bridge deck 2, in the longitudinal direction of the bridge deck 2, reinforcing ribs 22 are provided, and below the bridge deck 2, in the width direction of the bridge deck 2, an inner profile 18 is provided. Each inner contour 18 is arcuate. The bridge deck 2 is arranged in rows in the length direction and in columns in the width direction. Six reinforcing bars 22 (including both side plates of the decking 2) are located in a row, and a row of internal profiles 18 is provided between each two adjacent reinforcing bars 22. In the present embodiment, five inner profiles 18 located in the same row constitute reinforcing ribs in the width direction of the deck plate 2. Thereby, the lower (inner) of the deck slab 2 is reinforced in both the longitudinal direction and the width direction, so that the load-bearing capacity of the deck slab 2 is improved.

The contact surface of each inner contour 18 with the airbag layer 1 is coated with a surface coating 19;

a built-in clapboard 20 extends downwards below the bridge deck 2;

the built-in baffle 20 is used for limiting the displacement of the air bag layer 1 along the length direction of the bridge deck 2.

The function of the internal baffles 20 is to limit the displacement of the respective air bags along the length of the deck plate 2.

The built-in partition board 20 includes: a main partition 20.2 and an auxiliary partition 20.1. As the primary airbag 1.1 extends towards the adjacent pontoon module, a primary baffle 20.2 extends downwardly below the middle of each deck 2 for stability of each airbag deck 1. On both sides of the main partition 20.2 are the other ends of the three main airbags 1.1 of the left pontoon module and the one ends of the three main airbags 1.1 of the right pontoon module, respectively, as shown in fig. 2, 7 and 10.

In the present embodiment, the length of each airbag is the same as that of the deck plate 2, so the auxiliary bulkheads 20.1 are provided at both the fore and aft ends of each deck plate 2 for confining the auxiliary airbags 1.2 within the deck plate 2.
