[0026] Reference Figure 1-4 A reinforcement structure for a railway roadbed comprises a roadbed body 1: a left guard plate 5 and a right guard plate 2 are fixedly connected on the left and right sides of the roadbed body 1, a reinforcing plate 3 is fixedly connected to the lower sides of the left guard plate 5 and the right guard plate 2, the reinforcing plate 3 is fixedly connected to the roadbed body 1, and reinforcing ribs 4 are fixedly connected to the outer sides of the left guard plate 5 and the right guard plate 2, and the lower side of the reinforcing rib 4 is fixedly connected to the reinforcing plate 3, a hydrophobic structure 6 and a fastening structure 7 are arranged inside the roadbed body 1, and a plurality of reinforcing ribs 4 are arranged. When the staff reinforces the roadbed body 1, they first add the left guard plate 5 and the right guard plate 2 on both sides of the slope of the roadbed body 1, and then install the fastening structure 7, and then add the reinforcing plate 3 to the lower side of the guard plate, and then connect the reinforcing ribs 4 to reinforce the roadbed body 1, and finally install the hydrophobic structure 6.

[0027] The fastening structure 7 includes a hollow block 1 701 and a hollow block 2 704. The hollow block 1 701 is fixedly connected to the right side of the left guard plate 5, and the hollow block 2 704 is fixedly connected to the left side of the right guard plate 2. The hollow block 1 701 and the hollow block 2 704 are slidably connected. A round rod 702 is arranged inside the hollow block 1 701. The round rod 702 and the hollow block 1 701 are fixedly connected. A clamping block 703 is fixedly connected to the outer side of the round rod 702. A square groove 705 is provided on the inner wall of the hollow block 2 704. A spring 706 is arranged inside the square groove 705. The spring 706 and the hollow block 2 704 are fixedly connected. The other end of the spring 706 is fixedly connected to a clamping block 707. Two square grooves 705 are arranged, and a plurality of clamping blocks 703 are arranged. The clamping block 703 and the clamping block 707 are slidably connected. The outer side surfaces of the clamping block 703 and the clamping block 707 are arc shaped setting, when installing the guard plates on both sides, first a socket will be left on both sides of the roadbed for inserting hollow block 1 701 and hollow block 2 704, then put in hollow block 1 701 first, and then push hollow block 2 704 to let hollow block 2 704 slide into hollow block 1 701, and then the clamping block 703 slides down to push the clamping block 707, and the clamping block 707 squeezes the spring 706 and moves toward the depth of the square groove 705. When a clamping block 703 is stuck in, the clamping block 707 pops out so that the clamping block 703 cannot retreat. If the position of one clamping block 703 is not enough to reinforce the roadbed body 1, the staff will continue to push the guard plate to reinforce the roadbed body 1. The setting of multiple clamping blocks 707 can be used to set the fastening structure 7 between the guard plates according to the width of the roadbed body 1. The outer arc setting of the clamping block 707 and the clamping block 703 makes the fastening structure 7 easy to adjust.

When the hydrophobic structure 6 needs to be installed, holes for installing the hydrophobic structure 6 have been opened on the guard plate and the roadbed body 1 before this. At this time, the hydrophobic structure 6 can be installed. When water flows into the inside of the roadbed body 1, the water pipe 601 collects the water, and the water flows from the filter screen 603 into the circular hole 602, and then flows into the water pipe 601 from the circular hole 602, and finally flows out from both sides of the water pipe 601. The filter screen 603 can block large particles such as roadbed soil from the outside, allowing water to flow into the water pipe 601, so that the roadbed body 1 is prevented from being soaked in water for a long time, thereby preventing the roadbed settlement and slope collapse caused by the long-term soaking of the roadbed body 1.

[0029] Working principle: First, the staff installs the guard plates on both sides of the roadbed body 1. After the installation is completed with the fastening structure 7, the reinforcing plate 3 and the reinforcing rib 4 are installed and fixed. Finally, the hydrophobic structure 6 is installed to prevent the roadbed body 1 from being soaked in water for a long time.
