[0019] Example: Figures 1-5 As shown, this utility model provides a reinforcement structure for soft soil subgrade of highway, including partitions 1. Multiple partitions 1 are evenly distributed. The upper surface of the partitions 1 is roughened, resulting in a larger contact area when concrete is poured or backfilled, thus making the structure more stable. Multiple equally spaced fixing pins 2 are threaded onto the middle of the partitions 1. Each fixing pin 2 has a threaded screw 22 at its center. A sliding rod 23 is rotatably mounted at the bottom end of each screw 22, and the sliding rods 23 are slidably engaged in the middle of the fixing pins 2. Multiple sets of annularly arranged connecting rods 24 are movably mounted on the outer surface of each sliding rod 23. Multiple annularly arranged expansion plates 25 are provided at the lower part of each fixing pin 2. The lower parts of the connecting rods 24 are movably mounted on one side of the middle of each expansion plate 25. Limiting blocks 26 are fixedly mounted at the bottom end of each expansion plate 25. A cone head 27 is fixedly mounted at the bottom end of each fixing pin 2.

[0020] Each of the partitions 1 has a slider 13 fixedly installed on one side, and a groove 14 is provided on the side of the partitions 1 away from the slider 13. The sliders 13 are slidably engaged inside the groove 14. By setting the sliders 13 and the groove 14, it is more convenient to install the partitions 1 and to transport the partitions 1.

[0021] The upper part of each of the multiple cones 27 is provided with multiple limiting grooves 261 arranged in a ring array. The lower part of each of the multiple limiting blocks 26 is slidably locked inside the limiting grooves 261. By setting the limiting grooves 261, the limiting blocks 26 are limited by the limiting grooves 261, so that when the sliding rod 23 moves downward, it can drive the expansion plate 25 to move outward stably in cooperation with the connecting rod 24.

[0022] The lower part of the plurality of fixing pins 2 is provided with a plurality of annularly arranged clamping grooves 241, and the middle part of the plurality of connecting rods 24 is slidably clamped in the clamping grooves 241, so that when the screw rod 22 rotates and moves downward, only the sliding rod 23 moves downward without rotating.
