[0008] As a further solution of the utility model: a baffle is fixedly installed on the outer side of the insertion rod, and bolts are symmetrically threadedly connected to the top of the rotating disk.

[0009] As a further solution of the utility model: the mounting head is of trapezoidal design.

[0010] As a further solution of the utility model: a rubber pad is fixedly installed on the top of the baffle, and the bolts are pressed against the top of the rubber pad.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The utility model installs a trapezoidal installation head at one end of the insertion rod so that the installation head is inserted into the soil together with the insertion rod. Furthermore, the baffle is driven to rotate out from the inside of the installation head by rotating the turntable, so as to further prevent the insertion rod from being pulled out after being subjected to tension.

[0013] 2. The utility model further fixes the turntable by symmetrically arranging bolts on the top of the turntable, thereby preventing the rotation of the turntable from affecting the use effect of the baffle. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figures 1 to 3 In an embodiment of the utility model, a railway roadbed reinforcement device includes a roadbed body 4, reinforcement seats 12 are arranged on both sides of the roadbed body 4, and plug rods 3 are symmetrically arranged on the top of the reinforcement seat 12. The two plug rods 3 pass through the reinforcement seat 12 and are inserted into the soil. A mounting head 9 is fixedly installed at one end of the plug rod 3, and a mounting groove 8 is opened on the mounting head 9. A through hole 7 is opened inside the plug rod 3, and the through hole 7 is connected with the mounting groove 8. The bottom side of the inner part of the mounting groove 8 is rotatably connected with a rotating shaft 6, and the free end of the rotating shaft 6 passes through the plug rod 3 through the through hole 7. A turntable 1 is fixedly installed on the top of the plug rod 3, and a baffle 5 is fixedly installed on the outer side of the rotating shaft 6.

[0020] A baffle plate 2 is fixedly installed on the outer side of the insertion rod 3 , and bolts 11 are symmetrically threadedly connected to the top of the turntable 1 , and the turntable 1 is fixed by the bolts 11 .

[0021] The mounting head 9 is designed to be trapezoidal, and after being inserted into the soil, the possibility of the insertion rod 3 being pulled out is reduced through the top surface of the trapezoid.

[0022] A rubber pad 10 is fixedly mounted on the top of the baffle 2 , and a bolt 11 is pressed against the top of the rubber pad 10 to increase the friction between the bolt 11 and the baffle 2 .

[0023] The working principle of the utility model is:

[0024] When the utility model is used, the insertion rod 3 is passed through the reinforcement seat 12 and inserted into the soil together with the installation head 9. After being inserted into the soil, until the baffle plate 2 abuts against the top of the reinforcement seat 12, the bolt 11 is loosened, and the turntable 1 is turned with force. The turntable 1 drives the rotating shaft 6 to rotate, and the rotating shaft 6 drives the baffle plate 5 fixedly installed on its outer side to rotate out from the inside of the installation head 9 until the turntable 1 rotates ninety degrees and stops exerting force. At this time, the baffle plate 5 and the installation head 9 are vertically distributed, and at the same time act for the stability of the installation of the insertion rod 3. After the turntable 1 rotates to ninety degrees, in order to prevent the turntable 1 from shaking, it is necessary to tighten the bolt 11 again until the bolt 11 abuts against the rubber pad 10 and no longer rotates.
