Description

Technical Field

[0001] The present invention relates to the field of bridge construction, and more particularly to a floating bridge. Background Art

[0002] A floating bridge refers to a bridge that floats on the water with ships or pontoons instead of bridge piers.

[0003] The pontoons are a key component that enables a floating bridge to float on the water. According to the design plan, a sufficient number of pontoons are made and installed to ensure that the buoyancy can support the weight of the entire pontoon. The pontoons are usually composed of a closed structure with a certain buoyancy, such as a hollow plastic pontoon. When the pontoons are installed, they are placed on the water body according to the requirements of the design plan. Usually, cables or other fixings are used to connect the pontoons together to form the basic structure of the pontoon. Ensure that the layout spacing of the pontoons is appropriate, stable and evenly distributed to ensure the strength and stability of the pontoon, and then lay the road or bridge deck materials between the pontoons. These materials can be solid materials such as wooden boards and steel plates. These materials must be strong enough to support the weight of people and vehicles. These materials are fixed to the pontoon to ensure that they are flat and tightly connected together, and then use cables, cables or fixed piles at both ends of the pontoon to fix the pontoon to prevent it from drifting due to water flow or other factors. At the same time, anchoring equipment such as anchor chains or fixed piles are installed under the pontoon to further increase the stability of the pontoon.

[0004] The above-mentioned existing floating bridge is relatively troublesome to build, and the construction period is long.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Summary of the invention

[0017] The present invention is described in detail below in conjunction with the accompanying drawings and embodiments. Example

[0018] A floating bridge, such as Figure 1 and Figure 2As shown, it includes a plurality of pile bodies 15, a plurality of flexible guide rails 1, a plurality of inflatable floating bags 2 and a plurality of folding pedals 3. The pile body 15 adopts a concrete steel bar structure. The pile body 15 is inserted into the foundation on both sides of the river channel. The connection between the pile body 15 and the ground is reinforced by concrete, so that the pile body 15 has a high strength, can support the floating bridge, and improve the safety of the floating bridge. The flexible guide rail 1 is a steel cable and is used to span across the two banks. Both ends of the steel cable pass through the pile body 15. The end of the steel cable is equipped with a limiting ball for contacting the pile body 15. The diameter of the limiting ball is larger than the through hole on the pile body 15 for accommodating the steel cable to pass through, so that the limiting ball can fix the steel cable on the pile body 15. The inflatable floating bag 2 is provided with a sliding member 4 that is slidably connected to the flexible guide rail 1. The inflatable floating bag 2 is provided with an air inlet 5 and an air outlet The air inlet 5 and the air outlet 6 are blocked by a plug, and the air inlet 5 and the air outlet 6 are detachably connected to communicate with adjacent inflatable floating bags 2. Specifically, the air inlet 5 and the air outlet 6 are respectively equipped with quick-release joints that cooperate with each other. The folding pedal 3 is fixed to the top surface of the inflatable floating bag 2, and when the inflatable floating bag 2 is not inflated, the folding pedal 3 is in a folded state. When the inflatable floating bag 2 is filled with air, the folding pedal 3 is in an unfolded state. When the floating bridge is built, flexible guide rails 1 are arranged at both ends of the river channel, and then a predetermined number of inflatable floating bags 2 are installed on the flexible guide rails 1 through sliding members 4, and adjacent inflatable floating bags 2 are fixed through the air inlet 5 and the air outlet 6 to communicate with each other, and the air outlet 6 set most outside is sealed by components such as plugs. Since the inflatable buoy 2 is in a folded state, it occupies less space and can be installed together on the flexible guide rail 1. Then, the inflatable buoy 2 closest to the shore is inflated, and the gas enters the air inlet 5 of another inflatable buoy 2 adjacent to it through the air outlet 6 of the inflatable buoy 2. Similarly, all the inflatable buoys 2 can be inflated together, so that the inflatable buoy 2 is unfolded. After the inflatable buoy 2 is unfolded, the folding pedal 3 can also be unfolded with the unfolding of the inflatable buoy 2. When multiple inflatable buoys 2 are unfolded, the overall horizontal length of the multiple inflatable buoys 2 becomes longer, so that the inflatable buoy 2 will move along the length direction of the flexible guide rail 1. The sliding member 4 is slidably connected to the flexible guide rail 1, which can drive the inflatable buoy 2 to move along the length of the flexible guide rail 1. The flexible guide rail 1 can guide the movement of the multiple inflatable buoys 2 so that the inflatable buoys 2 can be moved to the other side of the river bank. The flexible guide rail 1 can also ensure that the arrangement spacing of the inflatable buoys 2 is appropriate, stable and evenly distributed to ensure the strength and stability of the floating bridge. After the multiple inflatable buoys 2 are spread out along the flexible guide rail 1, it is ensured that both ends of the flexible guide rail 1 pass through the pile body 15, and then the limit ball is installed to fix the flexible guide rail 1 between the two pile bodies 15, so that the floating bridge is formed, and the folding pedal 3 is unfolded for pedestrians to pass. The floating bridge of the present invention has the function of simple erection, a large number of components can be prefabricated, and the inflatable buoys 2 do not take up much space when not inflated, which is convenient for transportation, can be quickly unfolded at the construction site, has a short construction period, and is convenient for construction.

[0019] Specifically, Figure 2 and Figure 5 As shown, the inflatable float 2 is made of rubber material, which is corrosion-resistant. It is not easy to corrode and crack even if it floats on the water for a long time, and has a long service life. The sliding member 4 is a slide tube set on the steel cable. The slide tube is cylindrical. The slide tube and the inflatable float 2 are fixed by a woven lifting belt. The slide tube can accommodate the flexible guide rail 1 to pass through easily, so that it is relatively simple to fix the sliding member 4 on the flexible guide rail 1, and the flexible guide rail 1 and the slide tube can easily slide relative to each other, which is convenient for multiple inflatable floats 2 to be unfolded along the flexible guide rail 1 after being inflated. Furthermore, an oil chamber 12 is provided in the top of the slide tube, and a An oil filling hole 13 is connected to the oil chamber 12, and a plurality of oil outlet micropores 14 are provided on the top of the inner edge of the slide tube and are connected to the oil chamber 12. Before the inflatable float 2 is inflated, lubricating oil is injected into the oil filling hole 13 of some slide tubes, so that the lubricating oil enters the oil chamber 12 and penetrates into the flexible guide rail 1 through the oil outlet micropores 14, thereby reducing the surface friction coefficient of the flexible guide rail 1. As the inflatable float 2 is inflated and expanded, the slide tube moves along the flexible guide rail 1, which can lubricate the entire flexible guide rail 1, so that all slide tubes can move on the flexible guide rail 1 more smoothly, which is convenient for the expansion of multiple inflatable floats 2, thereby reducing the difficulty of erecting a floating bridge.

[0020] like Figure 2 As shown, the folding pedal 3 includes a plurality of small pedals, and adjacent small pedals are fixed by hinges, so that the folding pedal 3 can be folded in an S shape, and at the same time can drive the inflatable floating bag 2 to be compressed in the horizontal direction, thereby reducing the space occupied by the inflatable floating bag 2 when it is not inflated, and facilitating the large-scale transportation of the inflatable floating bag 2.

[0021] Further, such as Figure 1 and Figure 3As shown, a horizontally arranged diaphragm is integrally formed in the inflatable float 2, and the diaphragm divides the interior of the inflatable float 2 into a propulsion chamber 7 located at the top and a rear expansion chamber 8 located at the bottom. The propulsion chamber 7 is inflated for horizontally expanding the inflatable float 2, and the air inlet 5 is connected to the propulsion chamber 7. The rear expansion chamber 8 is used to longitudinally expand the inflatable float 2 and make the inflatable float 2 contact the water body. The inflation priority of the propulsion chamber 7 is higher than the inflation priority of the rear expansion chamber 8. When the propulsion chamber 7 is inflated and the rear expansion chamber 8 is not inflated, the bottom surface of the inflatable float 2 is higher than the water surface, and after the rear expansion chamber 8 is inflated, the inflatable float 2 floats on the water surface. In this embodiment, the bottom of the inflatable float 2 is overlapped upwards so that when the inflatable float 2 is not fully inflated, the inflatable float 2 does not When the multiple inflatable bladders 2 are in contact with the water surface and are interconnected and inflated, the propulsion chamber 7 first enters the air and the propulsion chamber 7 is preferentially unfolded, thereby increasing the overall horizontal length of the multiple inflatable bladders 2, so that the inflatable bladders 2 can move along the flexible guide rail 1. At the same time, the rear unfolding chamber 8 does not enter the air, so that the inflatable bladders 2 do not contact the water surface, and then when the inflatable bladders 2 move along the flexible guide rail 1, they will not be subject to resistance from the water flow, making it easier to unfold the inflatable bladders 2, thereby reducing the difficulty of erecting the floating bridge. After that, after the inflatable bladders 2 are evenly distributed on the river surface along the flexible guide rail 1, after the rear unfolding chamber 8 is aired, the inflatable bladders 2 are completely unfolded and float on the water surface, and can support the folding pedal 3 through the water surface to facilitate passage.

[0022] Further, such as Figure 3 and Figure 4 As shown, a channel 9 connecting the propulsion chamber 7 and the rear expansion chamber 8 is provided in the inflatable floating bag 2. Specifically, the channel 9 is arranged on the diaphragm and connects the two sides of the diaphragm. A gate plate 10 arranged in an annular shape is bonded in the channel 9. A plurality of valves 18 having elasticity and distributed in an annular array are integrally formed in the center of the gate plate 10. The plurality of valves 18 are mutually in conflict and cooperate with the gate plate 10 to block the channel 9. A normally closed port 11 is formed between the plurality of valves 18. After the propulsion chamber 7 is inflated and the inflatable floating bag 2 is horizontally expanded, the gas in the propulsion chamber 7 squeezes the valve 18 and passes through the valve 18 is deformed to open the normally closed opening 11 to allow gas to pass into the rear expansion chamber 8. Since multiple valves 18 conflict with each other, the propulsion chamber 7 and the rear expansion chamber 8 can be closed through the normally closed opening 11. When the propulsion chamber 7 is inflated, when the amount of gas in the propulsion chamber 7 is insufficient, the valve 18 is deformed, so that the propulsion chamber 7 can be inflated and expanded first before the rear expansion chamber 8. When the air pressure in the propulsion chamber 7 is high, the gas can squeeze the valve 18 open. After the valve 18 is deformed, the normally closed opening 11 is opened, and the gas can enter the rear expansion chamber 8, so that the inflatable float 2 is completely expanded.

[0023] like Figure 1 and Figure 2As shown, both sides of the inflatable buoy 2 are bonded with fixing ears 16, and a plurality of pile holes are opened on the fixing ears 16. The pile holes are provided with rear positioning piles 17 inserted into the river bottom. The positioning piles are fixed to the riverbed and pass through the fixing ears 16, so as to maintain the position of the inflatable buoy 2 on the river, fix the floating bridge, prevent it from drifting due to water flow or other factors, and improve the safety of the floating bridge.

[0024] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
