[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] like Figure 1 、 2 As shown, a roadbed reinforcement structure is designed, comprising: a roadbed 1, the upper surface of the roadbed 1 is flat, the side walls of the roadbed 1 are sloped, a water retaining plate 2 is anchored on the top of the roadbed 1, the water retaining plate 2 is inclined from the middle to both sides, an anchor rod 3 is fixed to the middle of the water retaining plate 2, a drainage layer 4 is laid above the water retaining plate 2, a drainage hole 42 is provided on the top of the drainage layer 4, a drainage pipe 41 is provided on the side wall of the drainage layer 4, an isolation layer 5 is laid on the top of the drainage layer 4, a concrete layer 6 is poured on the top of the isolation layer 5, an asphalt layer 7 is laid on the top of the concrete layer 6, and a water diversion mechanism 8 is provided on both sides of the roadbed 1.

[0026] The bottom of the water retaining plate 2 is laid on the upper surface of the roadbed 1. The bottom of the water retaining plate 2 is provided with ground spikes 22. After the water retaining plate 2 is laid flat, a road roller is used to roll on the water retaining plate 2 so that the ground spikes 22 and the anchor rods 3 are anchored into the roadbed 1, so that the position of the water retaining plate 2 is fixed. The water retaining plate 2 is made of impermeable material. The water retaining plate 2 prevents water from penetrating into the roadbed 1, slows down the loosening of the roadbed 1, keeps the roadbed 1 stable, and strengthens the compactness of the roadbed 1.

[0027] The anchor rod 3 passes through the middle of the water retaining plate 2. The bottom of the anchor rod 3 is a conical head. The conical head is anchored into the roadbed 1 when the water retaining plate 2 is installed. The upper part of the conical head is a hollow tube. The bottom of the hollow tube is also anchored into the roadbed 1. The side wall of the hollow tube is provided with a slurry hole 31. The top of the hollow tube is an opening. When pouring the concrete layer 6, the concrete is poured into the hollow tube, and the concrete slurry flows out from the slurry hole 31. After the concrete solidifies, the water retaining plate 2 is more tightly connected to the roadbed 1, making the effect of reinforcing the roadbed 1 more obvious.

[0028] The water baffles 2 are spliced ​​one by one along the extension direction of the roadbed 1. The weight of a single water baffle 2 is relatively light, which is convenient for transportation and position adjustment. Connecting holes 21 are opened at the front and rear ends of the water baffle 2. The connecting hole 21 is located in the middle of the water baffle 2. A connecting rod 9 is detachably connected to the connecting hole 21. The connecting holes 21 of the two adjacent water baffles 2 are inserted into the two ends of the connecting rod 9, and the side walls of the two water baffles 2 are fitted together. Then, bolts are driven into the top of the water baffle 2. The bolts pass through the top of the water baffle 2 and the top of the connecting rod 9 to connect the water baffle 2 to the connecting rod 9, thereby connecting multiple water baffles 2 into a whole.

[0029] The drainage layer 4 is laid on both sides of the water retaining plate 2. The drainage layer 4 has the same inclination as both sides of the water retaining plate 2. After inclination, it is convenient for the drainage pipe 41 to drain water to the outside of the roadbed 1 along the inclined direction. The highest point of the drainage layer 4 and the highest point of the water retaining plate 2 are in the same plane.

[0030] The drainage pipe 41 is horizontally arrayed on the side wall of the drainage layer 4. The drainage pipe 41 passes through the side wall of the drainage layer 4. The drainage hole 42 is provided above the drainage pipe 41. The bottom of the drainage hole 42 is connected to the drainage pipe 41. The water that penetrates from the top enters the drainage pipe 41 through the drainage hole 42. After entering the drainage pipe 41, the water flows out to the outside of the roadbed 1.

[0031] The isolation layer 5 is made of dense wire mesh or fiberglass mesh. The isolation layer 5 prevents large particles and a large amount of mud in the concrete from entering the drainage holes 42. The isolation layer 5 covers the tops of all drainage holes 42 to prevent the drainage holes 42 from being blocked and affecting the drainage efficiency.

[0032] A scale plate 43 is provided on the top outside of the drainage layer 4. The top of the scale plate 43 is flush with the top of the asphalt layer 7. Lines can be laid out on the scale plate 43, and the control line of the finished surface of the concrete layer 6 set during road design is marked on the scale plate 43. This makes it easy to control the elevation of the finished surface when pouring concrete. The top of the scale plate 43 is the elevation of the finished surface of the asphalt layer 7. The scale plate 43 also prevents asphalt or concrete from flowing into the outlet of the drainage pipe 41 during construction and affecting drainage.

[0033] The water diversion mechanism 8 includes a slope protection plate 81 and a drainage ditch 82. The slope protection plate 81 is anchored to the side wall of the roadbed 1. The drainage ditch 82 is arranged at the bottom of the slope protection plate 81. The top of the slope protection plate 81 is located below the drainage pipe 41. When the water in the drainage pipe 41 flows out, it is received by the slope protection plate 81 and then flows into the drainage ditch 82 and enters the sewer, so that the water is kept away from the roadbed 1.

[0034] A positioning block 811 is fixed to the upper surface of the slope protection plate 81, and a positioning rod 44 is fixed to the side wall of the drainage layer 4. In order to further fix the slope protection plate 81, the positioning rod 44 is passed through the positioning block 811, and a fastening nut is screwed to the outer side of the positioning rod 44. The fastening nut limits the positioning block 811 from moving outward, so that the slope protection plate 81 and the drainage layer 4 are connected together, the slope protection plate 81 is fastened, and the side wall of the roadbed 1 is further fixed.

[0035] The water that extends into the road surface is discharged through the drainage layer 4, the water retaining plate 2 prevents water from entering the roadbed 1, and the slope protection plate 81 blocks water from entering the side wall of the roadbed 1, thereby protecting the roadbed 1 in all directions to prevent water from entering the roadbed 1 and causing settlement and collapse, thereby achieving the reinforcement effect of the roadbed 1 and enhancing the ability of the roadbed 1 to resist rain and snow disasters.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
