Description

Technical Field

[0001] The utility model relates to the technical field of roadbed construction, in particular to a culvert abutment roadbed reinforcement structure. Background Art

[0002] A culvert refers to a drainage channel (water passage) built under the roadbed and below the road surface during highway construction in order to allow the highway to pass through the canal smoothly without hindering traffic. This structure allows water to flow under the highway.

[0003] The existing Chinese patent with publication number CN211340257U discloses a culvert abutment roadbed reinforcement structure, including a culvert, bottom columns fixedly provided on both sides of the bottom of the culvert, reinforcement mechanisms symmetrically provided on both sides of the culvert, the reinforcement mechanisms including a plurality of steps, each of which has a width of not less than two meters, each of which is inclined inward by 4%, and backfilled gravel soil is filled between the steps and the culvert. The utility model buries the bottom columns on both sides of the bottom of the culvert underground, and the grooves can increase the contact area between the bottom of the bottom columns and the ground, and the stabilizing plates can be embedded in the ground soil, thereby effectively stabilizing the culvert. The steps can increase the contact area between each layer of backfilled gravel soil and the roadbed, and the hexagonal abutments can provide good lateral support for the culvert to prevent the culvert from shifting. The connecting bars and reinforcing bars inside the culvert improve the bearing capacity of the culvert, thereby improving stability compared to the existing technology.

[0004] When the above patent is used, since the bottom of the hexagonal support column lacks a corresponding fixed and stable component, the probability of its deformation may increase when used for a long time. Therefore, there will be a certain degree of safety hazard and it is inconvenient to use.

[0005] Therefore, we made improvements and proposed a culvert abutment roadbed reinforcement structure. Utility Model Content

DETAILED DESCRIPTION

[0021] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0022] Example: Figures 1 to 5 As shown, the utility model is a culvert platform back roadbed reinforcement structure, including a culvert 1, both sides of the bottom of the culvert 1 are fixedly connected with bottom columns 2, the bottom of the bottom column 2 is fixedly connected with a ground rod 3, the top of the culvert 1 is provided with a qualified filler 4, the top of the qualified filler 4 is provided with a road surface structure layer 5, both sides of the culvert 1 are provided with steps 14, both sides of the culvert 1 are provided with reinforcement components, the reinforcement components include a reinforcement rod 15, one end of the reinforcement rod 15 is inserted into one side of the culvert 1 through a slot 16, the other end of the reinforcement rod 15 is inserted into the step 14, and the reinforcement rod 15 is provided with a fixed bottom column 2. Reinforcement components are provided on both sides of the bottom. By setting up the reinforcement components, the reinforcement rods 8 in the reinforcement components can be used to further improve the stability of the back roadbed of the culvert 1; the reinforcement component includes a reinforcement rod 8 rotatably set on one side of the reinforcement rod 15, and mounting seats 6 are fixedly connected to both side surfaces of the culvert 1. The end of the reinforcement rod 8 away from the reinforcement rod 15 is fixedly connected to the mounting seat 6 by a bolt 11. By setting up the reinforcement rod 8, a stable triangular structure can be formed with the side wall bracket of the culvert 1, which can better reinforce the back path of the culvert 1 and is more convenient to use.

[0023] There are multiple groups of mounting seats 6 on the reinforcement rod 15. The mounting seat 6 on the side of the reinforcement rod 15 close to the culvert 1 is rotatably connected to the mounting seat 6 through the rotating shaft 7. The rotating shaft 7 is fixedly connected to one end of the reinforcement rod 8. By arranging the reinforcement rod 8 between the reinforcement rod 15 and the culvert 1, a relatively stable triangular structure can be formed, thereby further improving the stability of the reinforcement rod 15; the end of the reinforcement rod 8 away from the mounting seat 6 is fixedly connected to the pin block 81, and a threaded hole 811 is opened on the pin block 81, and the threaded hole 811 is threadedly connected to the bolt 11.

[0024] A rotating rod 9 is rotatably connected to the mounting base 6 on the side of the reinforcement rod 15 away from the culvert 1. A stabilizing rod 91 is fixedly connected to the rotating rod 9. The provision of the stabilizing rod 91 further improves the stability of the reinforcement rod 15. A tapered portion 912 is fixedly connected to the end of the stabilizing rod 91 away from the rotating rod 9, and a pin 911 is fixedly connected to the outer peripheral wall of the stabilizing rod 91. The provision of the tapered portion 912 makes it easier to insert the stabilizing rod 91 into the backfill layer 10.

[0027] Backfill layers 10 are provided on both sides of the culvert 1. By providing multiple layers of compacted backfill layers 10, the soil stability on both sides of the culvert 1 can be further enhanced. Multiple groups of backfill layers 10 are stacked after compaction, and the laying thickness of each group of backfill layers 10 does not exceed 15 cm.

[0028] During operation, when it is necessary to reinforce the back roadbed of the culvert 1, one end of the reinforcing rod 15 is inserted into the slot 16, and then the other end of the reinforcing rod 15 is inserted into the step 14, and then the reinforcing rod 8 is fixedly connected to the end of the pin block 81 through the rotating shaft 7 and inserted into the mounting seat 6 fixedly connected to the side of the culvert 1, and then the position of the reinforcing rod 8 is fixed by the bolt 11, and at the same time, the tapered portion 912 of the stabilizing rod 91 is inserted into the ground by the rotating rod 9, which can achieve the purpose of stably supporting the reinforcing rod 15; then the backfill layer 10 set on both sides of the culvert 1 is backfilled on both sides of the culvert 1, and the backfill layer 10 adopts sandy soil or gravel with good permeability, and the backfill height of each backfill layer 10 does not exceed 15 cm, and then the lower backfill layer 10 is compacted by manual compaction and then stacked again.

[0029] 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.
