The first reinforcement pile 22 is inserted into the soil to stabilize the bottom of one side of the soft soil roadbed 1, and the second fixing plate 23 is pressed on the side of the soft soil roadbed 1, and the second reinforcement pile 24 is inserted into the interior of the soft soil roadbed 1, which plays the effect of fixing the second fixing plate 23 and improving the stability of the soft soil roadbed 1, preventing the soft soil roadbed 1 from slipping or collapsing, thereby enhancing the bearing capacity of the soft soil roadbed 1, and the second fixing plate 23 and the second reinforcement pile 24 are also arranged at an angle, which can make it difficult for the second reinforcement pile 24 to separate from the soft soil roadbed 1.

[0025] See also Figure 3 The reinforcement mechanism includes a fixing column 31 connected to the top of the first fixing plate 21, a first hollow block 32 is connected to the top of the fixing column 31, a threaded rod 33 is connected to the inside of the first hollow block 32, a first sleeve 34 is connected to the outside of the threaded rod 33, and one side of the first sleeve 34 is connected to the second fixing plate 23. The fixing column 31 can support the first hollow block 32 so that the first hollow block 32 can be connected to one side of the soft soil roadbed 1 at an angle, and the threaded rod 33 can rotate inside the first hollow block 32 and drive the first sleeve 34 through the rotation. The first sleeve 34 is connected to the second fixing plate 23, so that people only need to rotate the threaded rod 33 to drive the second fixing plate 23 and the second reinforcement pile 24 to move, which makes it more convenient to insert the second reinforcement pile 24 into the soft soil roadbed 1. At the same time, the threaded rod 33 is threadedly connected to the first sleeve 34, which can improve the connection stability between the first fixing plate 21 and the second fixing plate 23, so that the second fixing plate 23 and the second reinforcement pile 24 are not easy to move and fall over, and then can stably press the soft soil roadbed 1, so that the soft soil roadbed 1 is not easy to collapse.

[0026] In addition, a fixing rod 36 is connected to one side of the second fixing plate 23, and a second sleeve 35 is connected to one side of the first hollow block 32, and the second sleeve 35 is sleeved on the outside of the fixing rod 36. The second sleeve 35 can limit the second fixing plate 23 and the first sleeve 34 through the fixing rod 36, so that when the threaded rod 33 rotates, the first sleeve 34 can move smoothly and is not easy to rotate together.

[0027] See also Figure 3A second hollow block 41 is connected to one side of the first hollow block 32, and a threaded extrusion strip 42 is connected to the inside of the second hollow block 41. The threaded extrusion strip 42 is located at the lower side of the threaded rod 33 and can be moved by rotating inside the second hollow block 41.

[0029] See also Figure 3 A first thread groove 61 is provided on one side of the second fixing plate 23, and a bolt 63 is connected to the inside of the first thread groove 61. A second thread groove 62 is provided on one side of the second reinforcement pile 24, and the bolt 63 is connected to the inside of the second thread groove 62. The bolt 63 can be connected to the inside of the first thread groove 61 and the second thread groove 62 to connect the second fixing plate 23 and the second reinforcement pile 24. When the second reinforcement pile 24 is damaged or deformed, the bolt 63 can be rotated to disengage from the second thread groove 62 to facilitate the replacement of the second reinforcement pile 24.

[0030] See also Figure 3 The outer side of the second reinforcement pile 24 is connected with a barbed column 7, which can prevent the second reinforcement pile 24 from moving back after being inserted into the soft soil roadbed 1, thereby improving the stability of the second reinforcement pile 24 inside the soft soil roadbed 1. In addition, a plurality of barbed columns 7 are provided, which can make the second reinforcement pile 24 more stable inside the soft soil roadbed 1.

[0031] See also Figure 3 A reinforcing rod 8 is connected to one side of the fixing column 31, and one end of the reinforcing rod 8 is connected to the top of the first fixing plate 21. The reinforcing rod 8 can reinforce the connection between the first fixing plate 21 and the fixing column 31, so that the fixing column 31 is not prone to breakage and damage at the top of the first fixing plate 21.

[0032] See also Figure 1 and Figure 3 The outer side of the threaded rod 33 is provided with anti-skid patterns 9, which can play an anti-skid effect, so that when people rotate the threaded rod 33, it is not easy to slip and become difficult to rotate. Moreover, there are multiple anti-skid patterns 9, which can make the anti-skid effect better.

[0033] The anti-skid pattern 9 can protect the threaded extrusion strip 42, so that the inside of the threaded extrusion strip 42 is not easily penetrated by soil, and is not easily damaged by foreign objects such as stones.

Inside the second sleeve 35, the second hollow block 41 is fixed to one side of the first hollow block 32 by welding, the threaded extrusion strip 42 is threadedly connected to the inside of the second hollow block 41, one side of the limit rod 52 is cast as an integral part with the interior of the first sleeve 34, and the limit rod 52 is slidably connected to the inside of the limit groove 51, the bolt 63 is threadedly connected to the inside of the first thread groove 61 and the second thread groove 62, the barbed column 7 is cast as an integral part with the outer surface of the second reinforcement pile 24, one end of the reinforcement rod 8 is welded to the top of the first fixed plate 21, and the other end of the reinforcement rod 8 is welded to one side of the fixed column 31.

[0035] The working principle and use process of the utility model are as follows: when using the device, first place the first fixing plate 21 on one side of the soft soil roadbed 1, and insert the first reinforcement pile 22 into the soil to stabilize the first fixing plate 21, then rotate the threaded rod 33 to drive the first sleeve 34 and the second fixing plate 23 to move, and at the same time the second fixing plate 23 will drive the fixing rod 36 to slide inside the second sleeve 35, and when the second fixing plate 23 moves, it will also drive the second reinforcement pile 24 to be inserted into the soft soil roadbed 1 until the second fixing plate 23 presses the side of the soft soil roadbed 1, at this time the second reinforcement pile 24 can improve the stability of the soft soil roadbed 1, prevent the soft soil roadbed 1 from slipping or collapsing, and the threaded rod 33 The threaded connection with the first sleeve 34 can improve the connection stability of the first fixing plate 21 and the second fixing plate 23, so that the second fixing plate 23 and the second reinforcement pile 24 are not easy to move and fall over, and thus can stably press the soft soil roadbed 1, so that the soft soil roadbed 1 is not easy to collapse. At the same time, the barbed column 7 on the outside of the second reinforcement pile 24 can further prevent the second reinforcement pile 24 from moving back and away from the soft soil roadbed 1. At this point, the problem that the side reinforcement plates and reinforcement ribs are obliquely inserted into the soft soil roadbed 1 and contact with the upper side of the bottom reinforcement plate can be solved, but this will cause the connection between the bottom reinforcement plate and the side reinforcement plate to be loose, thereby making it easy for the side reinforcement plate to fall over, and thus it is difficult to stabilize the soft soil roadbed 1.

[0036] The above is only a preferred specific implementation method of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the utility model according to the technical solution and improved ideas of the utility model, which should be included in the protection scope of the utility model.
