Widening urban and rural roads and improving transportation capacity are urgent issues in the current transportation industry. Road widening structures are used when widening roads. Road widening structures refer to widening and renovating existing roads to meet the needs of increased traffic flow. Widening structures usually include increasing the number of lanes, adjusting lane widths, improving pavement materials, adding traffic lights, pedestrian crossing facilities and other measures to improve road capacity and safety. In the application process of road widening structures, there is often a problem that rainwater erodes the road surface for a long time, which easily causes damage to the road surface.

[0026] Figures 1 to 6An embodiment of a road widening structure of the utility model is shown, comprising a road widening structure segment 1, the road widening structure segment comprising a road widening structure body 2 and a drainage mechanism, the drainage mechanism comprising a drainage bottom plate 3 and a water inlet plate 4, the road widening structure body 2 comprising a first side wall 21 and a second side wall 22; the drainage bottom plate 3 is fixedly connected to the bottom of the road widening structure body 2, the drainage bottom plate 3 is provided with a drainage channel 35 capable of draining water along the length direction of the road widening structure body 2, the water inlet plate 4 is vertically arranged on the outer surface of the first side wall 21; the top of the water inlet plate 4 is provided with a water inlet, and the water inlet plate 4 is provided with a water inlet cavity 45 connected with the drainage channel 35. In this structure, rainwater on the surface of the road widening structure flows into the water inlet plate 4 through the water inlet, and then flows into the drainage bottom plate 3 for discharge, so that the road widening structure can well discharge rainwater on the road surface, thereby avoiding water accumulation on the road widening surface and preventing the road widening structure from having safety hazards when in use. By independently arranging the drainage system on the first side wall 21 and the bottom of the road widening structure body 2, the drainage system can be independently arranged from the road widening structure body 2, which is convenient for construction.

[0027] In this embodiment, the drainage bottom plate 3 includes a top plate and a bottom plate, and a plurality of support plates 31 are spaced apart between the top plate and the bottom plate along the width direction of the drainage bottom plate 3 to form a plurality of drainage channels 35; the support plates 31 are provided with through holes 34 for connecting the drainage channels 35. In this structure, the structural stability of the drainage bottom plate 3 is improved by providing the support plates 31, and a water inlet hole is provided on the side wall of the drainage bottom plate 3 connected to the water inlet plate 4. By providing the through holes 34 on the support plates 31, rainwater can flow from the water inlet hole to the drainage channels 35 and be discharged at the same time, thereby ensuring drainage efficiency.

[0028] In this embodiment, each of the drainage channels 35 is provided with a drainage port 32 at one end along the length direction of the road widening structure segment 1, and a plug-in protrusion 33 is provided at the other end that can be plugged into the drainage port 32 of the adjacent road widening structure segment 1. In this structure, the drainage bottom plates 3 of two adjacent sections form a plug-in structure through the drainage port 32 and the plug-in protrusion 33, which, on the one hand, facilitates the splicing construction of the drainage bottom plates 3 of different sections, and on the other hand, ensures the tightness of the connection of the drainage bottom plates 3 of each section, thereby ensuring the normal drainage of the road widening structure.

[0029] In this embodiment, the length of the water inlet plate 4 is the same as the length of the road widening structure segment, and a detachable filter mechanism is provided on the water inlet. This structure ensures that the water inlet has a larger effective area, further ensuring drainage efficiency; and by providing a detachable filter mechanism, it is convenient to clean or replace the filter mechanism in time, reducing the probability of blockage of the water inlet.

[0030] In this embodiment, the water inlet plate 4 is provided with a limit frame 44, the filtering mechanism includes a filter frame 41, the filter frame 41 is provided with a limit block 43 that can be inserted into the limit frame 44, and a filter screen is provided at the bottom of the filter frame 41. Through this structure, the filter frame 41 and the water inlet plate 4 form a detachable connection structure through the cooperation of the limit frame 44 and the limit block 43, which has a simple structure and is easy to disassemble and assemble.

[0031] In this embodiment, the second side wall 22 is provided with a plurality of positioning holes 221 penetrating the second side wall 22. In this structure, during the construction of the road widening structure, the road widening body is connected to the road body by setting steel bars penetrating the positioning holes 221, and then the concrete pavement is poured to ensure the stability of the connection between the steel bars and the road widening body.

[0032] In this embodiment, the outer side surface of the second side wall 22 is fixedly connected with an anti-slip block 5, and the outer side surface of the anti-slip block 5 facing the width direction of the road widening body is provided with a protrusion for increasing friction. In this structure, the anti-slip block 5 can increase the friction between the road widening structure body 2 and the road body, thereby improving the stability of the road widening structure body 2 during installation.

[0033] In this embodiment, the road widening structure body 2 includes a concrete layer 23, reinforcing steel bars 24 and support blocks 25. The support blocks 25 are symmetrically distributed on the inner side surfaces of the first side wall 21 and the second side wall 22. The reinforcing steel bars 24 are fixedly connected to the first side wall 21 at one end and to the second side wall 22 at the other end through the support blocks 25. The reinforcing steel bars 24 are provided with a plurality of reinforcing steel bars 24 distributed at intervals along the length direction of the road widening structure segment 1 and anchored inside the concrete layer 23. In this structure, the concrete layer 23 is used to form the road surface of the road widening structure body 2. The structural strength of the road widening structure body 2 is improved by providing the support blocks 25 and the reinforcing steel bars 24.

[0034] The working principle of the utility model is as follows: when the road widening structure is used, the road surface is widened by the main body 2 of the road widening structure, and the concrete layer 23 in the main body 2 of the road widening structure forms a concrete road surface. The main body 2 of the road widening structure is fixed at the installation position by setting the positioning hole 221, the stability of the main body 2 of the road widening structure can be increased by the anti-sliding block 5 during installation, and the structural strength of the main body 2 of the road widening structure can be increased by the support plate 31 and the reinforced steel bar 24, so as to ensure the stability of the main body 2 of the road widening structure during use. When water accumulates on the concrete road surface, the accumulated water flows from the water inlet into the water inlet cavity 45 through the side water inlet plate 4 of the main body 2 of the road widening structure, and finally flows into the drainage channel 35 in the drainage bottom plate 3. The filtering mechanism of the water inlet can filter the debris in the rainwater to avoid clogging of the drainage mechanism. The filter frame 41 is detachably connected to the water inlet plate 4, so that the staff can remove the filter frame 41 when necessary, clean or replace it, and ensure the normal use of the drainage mechanism.
