DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0018] In order to solve the technical problem that temporary roads are prone to tilting under the rolling of vehicles, the present invention provides a temporary pavement device, which can prop up the inclined road panel to restore the horizontal state and ensure the safe passage of vehicles.

[0019] It should be noted that the temporary pavement device and temporary road described in the present invention are used for but not limited to transporting wind power equipment. For the convenience of explanation, in the present invention, only the temporary pavement device and temporary road are used for transporting wind power equipment as an example for explanation. The principles used in transporting other equipment are essentially the same as those used in transporting wind power equipment, and will not be elaborated here.

[0020] See also Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of a temporary pavement device in one embodiment of the present invention. Figure 2 The temporary pavement device includes a pavement panel 1 and side legs 2.

[0021] The road panel 1 is provided with a first joint 11 and a second joint 12 at both ends thereof along its length direction, and the first joint 11 and the second joint 12 are connected in cooperation, and two road panels 1 are connected together through the first joint 11 and the second joint 12. A plurality of first mounting grooves 13 are formed on the lower surface of the road panel 1, and the first mounting grooves 13 are symmetrically arranged on both sides of the width direction of the road panel 1. A first pipe is also formed inside the road panel, and the first pipe is connected to the first mounting groove 13 and the outer side surface of the road panel 1 in the width direction.

[0022] A plurality of side legs 2 are arranged in a one-to-one correspondence in the first mounting groove 13. The side legs 2 include an outer bag 21, which is elastic and fixedly connected to the inner wall of the first mounting groove 13, and the outer bag 21 also has an opening communicating with the first pipe.

[0023] By injecting water into the outer bag 21 under pressure through the first pipe, the outer bag 21 can expand and protrude from the first mounting groove 13. When the foundation collapses and causes the road panel to tilt, water is injected into the side legs 2 at the depression to make the outer bag 21 protrude to lift the road panel 1, thereby improving the levelness of the road panel 1 and improving the traffic conditions of the temporary road.

[0024] In some embodiments, a detection device is also provided on the road panel 1 to detect the degree of inclination, i.e., the horizontality, of the upper surface of the road panel 1, so as to guide the operator to inject water into the corresponding side legs 2 to expand them and restore the road panel 1 to a normal state. Since the vehicle can rely on its own chassis to overcome a certain degree of inclination of the road when driving, there is no high requirement for the horizontality of the road panel 1. Therefore, in other embodiments, the operator can also visually determine which road panels 1 have a large inclination and need to be repaired by the side legs 2.

[0025] In a preferred embodiment, the detection device is also connected to the air pump or water pump connected to the first pipeline to control the working state of the air pump or water pump, and automatically controls the operation of the air pump or water pump according to the levelness of the upper surface of the road panel 1 to adjust the state of the road panel 1, so that the road panel 1 can be better installed at a designated position on the ground or underwater.

[0026] In this embodiment, the first joint 11 and the second joint 12 are connected by means of a slot as shown in the figure. In other embodiments, the first joint 11 and the second joint 12 may also be hinged by means of a shaft and a collar to adapt to more rugged land conditions.

[0027] In some embodiments, a quick connector 14 is formed on the outer side of the road panel 1 in the width direction, and the first pipeline is connected to the quick connector 14. The quick connector 14 preferably adopts a universal standard connector so that a water pump or an air pump and other equipment can be quickly connected thereto. In addition, a sealing plug, a valve, or the like can be used to close the pipeline opening on the quick connector 14.

[0028] See also Figure 3 In some embodiments, a plurality of intermediate cavities 15 and a second pipe are formed in the road panel 1, and the second pipe connects each intermediate cavity 15 and the quick connector 14. The road panel 1 can be made of a flexible material, and the volume of the road panel 1 is reduced by squeezing the intermediate cavity 15 when it is stored. When it is in use, the intermediate cavity 15 is filled with air to support the road panel 1. Furthermore, the intermediate cavity 15 can be filled with water to obtain sufficient bearing strength by using the incompressibility of the liquid. In other embodiments, a rigid material road panel 1 can also be used, and the intermediate cavity 15 is used to reduce the weight of the road panel 1.

[0029] In some embodiments, the road panel 1 includes a rubber anti-skid layer 16, a steel wire layer 17, and a cord layer 18 arranged in sequence from the outside to the inside. The surface of the rubber anti-skid layer 16 has an anti-skid pattern, which is a strip-shaped protrusion along the width direction of the road panel 1 and is arranged at intervals along the length direction of the road panel 1. The steel wire layer 17 is located on the inner side of the rubber anti-skid layer 16 to provide strength support when carrying a vehicle. The cord layer 18 is coated outside the middle cavity 15 to provide constraint strength for the middle cavity 15 to prevent the middle cavity 15 from being ruptured under pressure. The rubber anti-skid layer 16, the steel wire layer 17, and the cord layer 18 are connected as a whole by rubber.

[0030] See also Figure 4 and Figure 5 , Figure 4 for Figure 2 Schematic diagram of the structure of the middle and side legs; Figure 5 Schematic diagram of the internal structure of the side leg. In some embodiments, the side leg 2 also includes a gravity ball 22 and a hose 23. The gravity ball 22 is hollow and has multiple through holes. The hose 23 connects the first pipe and the gravity ball 22. The gravity ball 22 acts as a counterweight and will always fall at the lowest point in the outer bag 21. In this way, when the water in the side leg 2 needs to be drained after use, all the water can be quickly pumped out. In this embodiment, the side leg 2 is long and narrow, so two gravity balls 22 are set at both ends of the outer bag 21, and the water can be pumped out no matter which direction it is tilted.

[0031] Please see again Figure 2 In some embodiments, the temporary pavement device further includes an intermediate leg 3, a second mounting groove 19 is formed on the lower surface of the road panel 1, and a third pipe is formed on the road panel 1, and the third pipe connects the second mounting groove 19 and the quick connector 14. The intermediate leg 3 is arranged in the second mounting groove 19, and the intermediate leg 3 can extend out of the second mounting groove 19 to be inserted into the ground, thereby playing the role of fixing the road panel 1.

[0032] See also Figure 6In some embodiments, the middle leg 3 adopts the structural principle of a suction anchor, including a fixed leg 31A and an exhaust pipe 32A. The lower end of the fixed leg 31A is open, and an exhaust port is formed at the upper end. The lower end of the exhaust pipe 32A is connected to the exhaust port, and the upper end of the exhaust pipe 32A is detachably connected to the third pipe. When in use, the fixed leg 31A extends out of the second mounting slot 19, and the fixed leg 31A will be inserted into the ground for a distance under the action of gravity. Then the third pipe is connected to the exhaust pump to generate negative pressure in the fixed leg 31A. Under the action of air pressure, the fixed leg 31A will gradually move downward until it is completely inserted into the ground.

[0033] See also Figure 7 In other embodiments, the middle leg 3 adopts the hydraulic principle, including a fixed leg 31B and a spring 32B, the lower end of the fixed leg 31B is open, the upper end is closed, the fixed leg 31B is sealed and slidably connected with the second mounting groove 19, and the spring 32B is fixedly connected with the fixed leg 31B and the second mounting groove 19. When in use, the third pipe is connected to the upper water pump, and water is injected into the third pipe to push the fixed leg 31B downward and inserted into the soil.

[0034] In a preferred embodiment, whether the middle leg 3 adopts a suction anchor structure or a hydraulic telescopic structure, it can adopt a multi-tube sleeve connection form to control the depth of insertion into the soil to achieve a better fixing effect. It is easy to understand that the detection device can also be connected to the air pump or water pump connected to the third pipeline to automatically control the state of the middle leg 3.

[0035] See also Figure 1 , Figure 8 and Fig. 9 In some embodiments, the temporary pavement device further includes a buoy 4. When the temporary pavement device is laid below the water surface, the buoy 4 is required. The buoy 4 includes a cylinder 41, a connecting pipe 42 and a float 43. One end of the cylinder 41 is detachably connected to the quick connector 14, and the other end extends upward. A plurality of extension pipes 411 are formed in the cylinder 41, and the extension pipes 411 connect the two ends of the cylinder 41. One end of the extension pipe 411 is connected to the pipe opening of the quick connector 14 in a one-to-one correspondence, that is, it is connected to the first pipe, the second pipe, the third pipe, etc. described above. The lower end of the connecting pipe 42 is inserted into each extension pipe 411 in a one-to-one correspondence and is sealed and slidably connected with the extension pipe 411. The upper end of the connecting rod 42 is formed with the same quick connector, and the float 43 is fixedly connected to the connecting pipe 42 to provide buoyancy for the connecting pipe 42.

[0036] When the road panel 1 is below the water surface, the quick connector 14 has sealing problems and is difficult to connect with the water pump and the air pump. By installing the buoy 4 on the quick connector 14, it is equivalent to extending the quick connector 14 to the water surface, thereby solving the above problems. The float 43 can float on the water surface by its own buoyancy, and then the connecting tube 42 and the cylinder 41 are sealed and slidably connected, so as to adaptively adjust the extension length of the connecting tube 42 to adapt to different water depths.

[0037] See also Fig.10 , Fig.10 A schematic diagram of the structure of a temporary road provided by an embodiment of the present invention. The temporary road includes a plurality of temporary pavement devices 100. Along the extending direction of the road, each road panel 1 is sequentially connected through a first joint 11 and a second joint 12. Each intermediate cavity 15 is then filled with water or air through a second pipe and the second pipe is closed to enhance the bearing capacity of the temporary road.

[0038] When the ground condition is slippery and the temporary road needs to be fixed more firmly, air is pumped or water is injected into the middle leg 3 through the third pipe, so that the middle leg 3 is extended and inserted into the soil to prevent the road panel 1 from sliding.

[0039] When it is necessary to lay a temporary road in a shallow water area, the temporary road surface device is located underwater. At this time, a buoy 4 needs to be installed on the quick connector 14. The upper end of the buoy 4 also has a similar quick connector and floats on the water surface, so as to facilitate the connection of water pumps, air pumps and other equipment.

[0040] The temporary road can also float on the water and be used as a floating bridge. When in use, the second pipe is connected to the air pump to inflate the middle cavity 15. After the middle cavity 15 expands to the maximum, the second pipe is closed. The temporary road spliced ​​with the temporary pavement device 100 treated in this way can float on the water and be used as a floating bridge. It is easy to understand that by controlling the inflation amount of the middle cavity 15 and changing the buoyancy of the temporary pavement device 100, the height of the temporary pavement device 100 exposed above the water surface can also be controlled, and even the upper surface of the road panel 1 is almost flush with the water surface, so that the temporary road can also be used as an invisible floating bridge.

[0041] The specific implementation of the present invention described above does not constitute a limitation on the protection scope of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the protection scope of the claims of the present invention.
