[0030] It should be noted that the airbag body 3 is fixedly installed at the bottom of the upper steel plate 1, and the end of the airbag body 3 away from the upper steel plate 1 is fixedly connected to the lower steel plate 2. The surface of the airbag body 3 is provided with an installation plate. The airbag body 3 is fixed to the upper steel plate 1 and the lower steel plate 2 by the fixing plate to prevent the airbag body 3 from separating from the upper steel plate 1 and the lower steel plate 2 when inflated. Multiple upper steel plates 1 are spliced ​​together by the fixing mechanism. By rapidly inflating and pressurizing the airbag body 3, a high-rigidity bridge is formed.

[0031] Specifically, the fixing part includes a fixing frame 5, which is fixedly installed on one side of the upper steel plate 1. A fixing groove is provided at the end of the fixing frame 5 away from the upper steel plate 1, and the fixing groove is adapted to the connecting part.

[0032] Specifically, the connecting part includes a connecting frame 6, one end of which is fixedly connected to the end of the upper steel plate 1 away from the fixed frame 5, and the end of the connecting frame 6 away from the upper steel plate 1 is adapted to the fixing groove;

[0033] It should be noted that the fixing frame 5 is fixedly installed on one side of the upper steel plate 1, and the connecting frame 6 is fixedly installed on the end of the upper steel plate 1 away from the fixing frame 5. The end of the connecting frame 6 away from the upper steel plate 1 is matched with the fixing groove. The end of the connecting frame 6 away from the upper steel plate 1 is inserted and connected to the fixing groove. Through the cooperation of the fixing frame 5 and the connecting frame 6, multiple upper steel plates 1 can be spliced ​​together. Multiple upper steel plates 1 can be spliced ​​or disassembled quickly as needed, improving construction efficiency and reducing transportation volume. After the assembly is completed, the airbag body 3 is quickly inflated and pressurized to form a high-rigidity trestle bridge, realizing the rapid reinforcement of soft soil sites and meeting the requirements for the movement and operation of large equipment.

[0034] Specifically, the fixed frame 5 has slots on both sides, and the connecting frame 6 has an installation groove at the end away from the upper steel plate 1. A limit plate 9 is slidably inserted into the installation groove. A fixed block 8 is fixedly installed at one end of the limit plate 9. The end of the fixed block 8 away from the limit plate 9 extends out of the installation groove and is inserted into the slot.

[0035] Specifically, a spring 10 is provided in the mounting groove. One end of the spring 10 is fixedly connected to the inner wall of the mounting groove, and the other end of the spring 10 is fixedly connected to the end of the limiting plate 9 away from the fixing block 8.

[0036] It should be noted that the limiting plate 9 is fixedly installed in the mounting groove. One end of the limiting plate 9 is fixedly connected to the fixing block 8. The end of the fixing block 8 away from the limiting plate 9 extends out of the mounting groove and is inserted into the slot. The spring 10 is set in the mounting groove. One end of the spring 10 is fixedly connected to the inner wall of the mounting groove. The other end of the spring 10 is fixedly connected to the end of the limiting plate 9 away from the fixing block 8. The connecting frame 6 is inserted into the fixing groove. The fixing block 8 is pressed by the inner wall of the fixing frame 5, causing the fixing block 8 to move into the mounting groove. When the connecting frame 6 moves into the fixing groove, the spring 10 pushes the limiting plate 9 to move. The movement of the limiting plate 9 drives the fixing block 8 to move, causing the fixing block 8 to move out of the mounting groove and be inserted into the slot. The fixing block 8 fixes the fixing frame 5 and the connecting frame 6, preventing the fixing frame 5 and the connecting frame 6 from separating and affecting the operation requirements.

[0037] A fixing bolt 7 is inserted and connected to the top of the fixing bracket 5, and the threaded end of the fixing bolt 7 is inserted and connected to the threaded top of the connecting bracket 6.

[0038] It should be noted that one end of the fixing bolt 7 is inserted into the top of the fixing frame 5, and the threaded end of the fixing bolt 7 is inserted into the fixing frame 5 and threaded into the top of the connecting frame 6, connecting the connecting frame 6 into the fixing groove. The fixing block 8 is pressed by the inner wall of the fixing frame 5, causing the fixing block 8 to move into the mounting groove. When the connecting frame 6 moves into the fixing groove, the spring 10 pushes the limiting plate 9 to move. The movement of the limiting plate 9 drives the fixing block 8 to move, causing the fixing block 8 to move out of the mounting groove and insert into the slot. The fixing block 8 fixes the fixing frame 5 and the connecting frame 6. The fixing bolt 7 is used to further strengthen the connection between the fixing frame 5 and the connecting frame 6 to prevent the fixing frame 5 and the connecting frame 6 from separating and affecting the operation requirements.

[0039] Both the upper steel plate 1 and the lower steel plate 2 have connecting grooves at their end corners. Multiple connecting grooves are symmetrical to each other, and tie bolts 4 are rotatably inserted and connected in the connecting grooves.

[0040] It should be noted that the two ends of the tie bolt 4 are rotatably interlocked with multiple connecting slots. Before inflating the airbag body 3, the tie bolt 4 is pre-tightened by turning it. The airbag body 3 is then inflated, so that the tie bolt 4 is in a tension state after inflation, forming a high-rigidity support structure, evenly distributing the load, and avoiding local settlement of soft foundations. After use, the fixing bolt 7 is unscrewed, the fixing block 8 is pressed, and the fixing block 8 is moved into the installation slot. The upper steel plate 1 is pulled to separate the fixing frame 5 and the connecting frame 6, thereby separating the multiple upper steel plates 1, emptying the airbag body 3, and bringing the upper steel plate 1 and the lower steel plate 2 closer together for quick disassembly, reducing the overall volume, and facilitating transportation and reuse.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
