Description

Technical Field

[0001] The utility model relates to the technical field of road engineering, and specifically relates to a splicing structure for new and old roadbeds and road surfaces in road engineering. Background Technique

[0002] Civil engineering is a general term for the science and technology of constructing various land engineering facilities. It refers to both the materials, equipment used and the technical activities such as surveying, design, construction, maintenance, and repair, and also refers to the objects of engineering construction, that is, various engineering facilities built on the ground, underground, or on land, directly or indirectly serving human life, production, military, and scientific research. Civil engineering refers to the surveying, planning, design, construction, installation, and maintenance and other technical work and the completed engineering entities for the construction, reconstruction, or expansion of various engineering buildings, structures, and related supporting facilities other than building construction. When widening or lengthening an old roadbed body, the new and old roadbeds are usually connected through a splicing structure.

[0003] As disclosed in the patent with the authorization announcement number CN218842765U, there is disclosed a splicing structure for new and old roadbeds and road surfaces in road engineering, including an old roadbed body. A positioning connection component is fixedly installed on one side of the old roadbed body. The positioning connection component includes a new roadbed, a gravel layer, a concrete layer, and a positioning frame. A new roadbed is fixedly connected to the top of one side of the old roadbed body. A gravel layer is fixedly connected to the top of the new roadbed. A concrete layer is fixedly connected to the top of the gravel layer. A positioning frame is embedded and connected inside the old roadbed body, the new roadbed, the gravel layer, and the concrete layer, which is convenient for workers to fixedly connect both the gravel layer and the concrete layer to the old roadbed body. Through the positioning connection component, the utility model can make the old roadbed body, the new roadbed, the gravel layer, and the concrete layer be fixedly connected to each other, thereby completing the stable splicing of the old roadbed body and the new roadbed, ensuring the stability of the connection between the old roadbed body and the new roadbed, and improving the structural strength of the connection.

[0004] However, for the splicing mechanism mentioned in this patent, the construction cost of adding a positioning frame is relatively large, which will exceed the engineering budget of the overall road project, and when the road surface is damaged, the positioning frame will be exposed, causing damage to the driving vehicles.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0023] Please refer to Figures 1 - 4 As shown, a technical solution provided by the present utility model:

[0024] A splicing structure for the old and new roadbeds and road surfaces in road engineering, including a splicing mechanism 101, a drainage mechanism 102, and a base mechanism 103.

The splicing mechanism 101 includes an old road surface 104. A lower connection layer 105 is fixedly installed at the right end of the old road surface 104. A groove 106 is opened at the top of the lower connection layer 105. A steel bar 201 is fixedly installed inside the groove 106. An adhesive material 202 is fixedly installed at the top of the lower connection layer 105.

[0025] Through the above solution, the contact area with the new road surface can be increased through the lower connection layer. Steel bars can be placed through the groove, and convex blocks can be formed in the groove when the new road surface is laid. The overall splicing is made more firm through the adhesive material.

[0026] In this embodiment, preferably, the splicing mechanism 101 further includes a new road surface 203. A upper connection layer 204 is fixedly installed at the left end of the new road surface 203. The bottom end of the upper connection layer 204 is fixedly installed at the top end of the adhesive material 202. A convex block 205 is fixedly installed at the bottom end of the upper connection layer 204, and the convex block 205 is fixedly installed in the groove 106.

[0027] Through the above solution, the contact area with the old road surface can be increased through the upper connection layer, and the splicing of the new and old road surfaces can be made more stable by the convex block being inserted into the groove.

[0028] In this embodiment, preferably, the drainage mechanism 102 includes a drainage chute 206, and the drainage chute 206 is fixedly installed at the right end of the new road surface 203 and the left end of the old road surface 104.

[0029] Through the above solution, accumulated water can be discharged through the drainage chute.

[0030] In this embodiment, preferably, a limiting block 301 is fixedly installed in the middle of the drainage chute 206. A filter plate 302 is movably installed on the limiting block 301, and a handle 303 is fixedly installed on the filter plate 302.

[0031] Through the above solution, the filter plate can be limited and installed through the limiting block, the filter plate can be taken and placed through the handle, and sundries in the accumulated water can be filtered through the filter plate.

[0032] In this embodiment, preferably, a clamping groove 304 is formed at the top end of the drainage chute 206. A groove cover 403 is movably installed in the clamping groove 304, and a water inlet groove 305 is formed in the groove cover 403.

[0033] Through the above solution, the groove cover can be clamped tightly through the clamping groove, the drainage chute can be closed through the groove cover to prevent pedestrians from falling in, and accumulated water can enter the drainage chute through the water inlet groove.

[0034] In this embodiment, preferably, the base mechanism 103 includes a rammed earth layer 306. Drainage chutes 206 are fixedly installed on both sides of the top end of the rammed earth layer 306, and a crushed stone layer 401 is fixedly installed at the top end of the rammed earth layer 306.

[0035] Through the above solution, the bearing capacity of the foundation can be improved through the rammed earth layer and the crushed stone layer, avoiding ground collapse, and the crushed stone layer can ensure the drainage performance in the foundation.

[0036] In this embodiment, preferably, a water-stable layer 402 is fixedly installed at the top end of the crushed stone layer 401, and a new road surface 203 and an old road surface 104 are fixedly installed at the top end of the water-stable layer 402.

[0037] Through the above solution, the water-stable layer can ensure the stability of the foundation even when it encounters water.

[0038] When a new-old roadbed and pavement splicing structure of this embodiment is in use, the user cuts and separates the old pavement 104 through a cutting device, and at the same time cuts out a lower connecting layer 105 on the old pavement 104. Then, the soil at the separated gap is compacted through a compaction device to make it consistent with the original compacted soil layer 306. Then, gravel is laid on the top of the compacted soil layer 306 and the water-stable layer 402 is laid on the top of the gravel layer 401. The water-stable layer 402 is made of concrete material. After the water-stable layer 402 is laid, the overall foundation is completed. When laying the new pavement 203, first, a groove 106 is opened on the lower connecting layer 105. After the steel bars 201 are placed, an adhesive material 202 is applied on the surface of the lower connecting layer 105. At this time, the paving device lays asphalt on the top of the water-stable layer 402 and the lower connecting layer 105 for paving. When paving, the asphalt in the groove 106 forms a convex block 205 and adheres to the groove 106 through the adhesive material 202. At the same time, the lower connecting layer 105 and the upper connecting layer 204 are adhered through the adhesive material 202. After the asphalt is paved, a new pavement 203 is formed. At this time, the new pavement 203 wraps the steel bars 201 inside, making the splicing of the new and old pavements 104 more stable. After the new pavement 203 is laid, a drainage chute 206 is installed at the right end of the new pavement 203 and the top of the water-stable layer 402. Then, the filter plate 302 is placed on the top of the limit block 301 through the handle 303. Finally, the groove cover 403 is snapped into the card slot 304. When draining, the accumulated water on the road surface enters the drainage chute 206 through the water inlet groove 305. At this time, the filter plate 302 filters the large-particle impurities in the accumulated water, and then the accumulated water is discharged through the drainage chute 206.
