Description

Technical Field

[0001] The utility model relates to the technical field of road paving, in particular to a curing-free cement-stabilized crushed stone structure. Background Art

[0002] Cement stabilized gravel uses graded gravel as aggregate, a certain amount of cementitious material and sufficient mortar volume to fill the gaps in the aggregate, and is spread and compacted according to the interlocking principle. Its compaction degree is close to its density, and its strength mainly depends on the interlocking principle between the gravel. At the same time, there is sufficient mortar volume to fill the gaps in the aggregate. It has high initial strength, and the strength increases with age and quickly forms a board, so it has higher strength, better impermeability and frost resistance.

[0003] For example, the utility model with application number CN202120045632.5 discloses a cement-stabilized recycled gravel base road structure. The utility model uses recycled building materials with different thicknesses and proportions on the bottom layer of the road, and provides two mixed material layers with different compressive strengths in a double-layer structure, thereby improving the overall bearing capacity and pressure resistance of the road and reducing the cost of road construction. The concrete surface layer is constructed in two layers by laying concrete surface layers of different thicknesses, and an emulsified asphalt layer is laid between the two surface layers, which greatly reduces the overall shrinkage and cracking situation, and further improves the quality of later construction. However, due to the smooth surface of the cement-stabilized gravel layer, when the asphalt pavement is subsequently laid, the connection strength between the asphalt layer and the cement-stabilized gravel layer is relatively general.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved to provide a curing-free cement-stabilized gravel structure. Utility Model Content

The top of the stabilizing frame is provided with an embedding groove, and a magnet is arranged inside the lower end of the embedding groove.

[0009] Furthermore, the positioning assembly also includes a connecting block and an elastic plate. The connecting block is fixed on the top of the magnet, and the elastic plate is arranged on the upper end of the connecting block.

[0010] Furthermore, the connecting block is in an inverted T shape, and the front-to-back width of the connecting block is equal to the front-to-back width of the elastic plate.

At the same time, the elastic plate can be moved to place the protective film between the anti-slip pads, and the protective film can be quickly fixed after releasing the hand, so that the protective film can shield and protect the top of the water-stabilizing layer during laying, and can also reduce the evaporation of water below, which is beneficial to improving the quality of the water-stabilizing layer during laying. At the same time, the reflective strip can also be used to warn pedestrians in the dark environment at night to prevent pedestrians from entering and damaging the incompletely formed water-stabilizing layer. After forming, it can be pulled out of the embedded groove by pulling the elastic plate hard for recycling and reuse. BRIEF DESCRIPTION OF THE DRAWINGS

The stabilizing plate 302 can improve the connection strength between the fixing column 301 and the water-stable layer 1. The top of the fixing column 301 is connected to the stabilizing frame 303, and a stabilizing rod 304 is arranged inside the stabilizing frame 303, which can utilize the mesh stabilizing rod 304 to fully combine with the asphalt layer, so as to enhance the connection strength between the asphalt layer and the water-stabilizing layer 1, so that the road surface is more stable after paving. Positioning grooves 305 are provided at the four ends of the bottom of the stabilizing frame 303, and positioning columns 306 are embedded in the positioning grooves 305. The split stabilizing frame 303 is also convenient for transporting it during paving, which is beneficial to improving the convenience during paving. The positioning columns 306 are fixedly connected to the fixing columns 301, and four positioning columns 306 are arranged on the top of the fixing columns 301. The positioning grooves 305 and the positioning columns 306 are used to facilitate the rapid erection of the stabilizing frame 303 on the fixing columns 301 during paving.

[0023] like Figure 2 and Figure 3 As shown, positioning components 4 are provided at both left and right ends of the top of the stabilizing frame 303, and the positioning components 4 include an embedding groove 401 and a magnet 402. The top of the stabilizing frame 303 is provided with an embedding groove 401, and the lower end of the embedding groove 401 is provided with a magnet 402.

The top of the magnet 402 is fixed with a connecting block 403, and the upper end of the connecting block 403 is provided with an elastic plate 404. The connecting block 403 is in an inverted T shape, and the front and rear widths of the connecting block 403 are equal to the front and rear widths of the elastic plate 404. After the elastic plate 404 is pulled out, the connecting block 403 can be pushed to separate the magnet 402 from the elastic plate 404 so as to replace them partially. The bottom size of the elastic plate 404 is consistent with the top size of the embedding groove 401, and the elastic plate 404 is slidably connected to the magnet 402. When the elastic plate 404 is moved, the magnet 402 is moved. 4 and place the protective film in between, and the protective film can be quickly fixed after releasing, so that the protective film can cover and protect the top of the water-stabilizing layer 1 during laying, and can also reduce the evaporation of water below, which is beneficial to improving the quality of the water-stabilizing layer 1 during laying, and after maintenance, it only needs to pull the elastic plate 404 hard to pull it out from the embedded groove 401 for recycling and reuse. The positioning component 4 also includes an anti-skid pad 405 and a reflective strip 406. The anti-skid pad 405 is provided on one side of the elastic plate 404, and the reflective strip 406 is connected to the other side of the elastic plate 404.

Then, the stabilizing frame 303 is quickly built on the fixing column 301 by using the positioning groove 305 and the positioning column 306 during laying. Then, the elastic plate 404 can be quickly fixed in the embedding groove 401 by adsorbing the stabilizing frame 303 with the magnet 402, so that the elastic plate 404 can be moved and the protective film can be placed between the anti-slip pads 405, and after releasing the hand, it can be The protective film is quickly fixed so that it can shield and protect the top of the water-stabilizing layer 1 during laying, and can also reduce the evaporation of water below. At the same time, the reflective strip 406 can also be used to warn pedestrians around in a dark environment at night. Finally, after forming, it is only necessary to pull the elastic plate 404 hard to extract it from the embedded groove 401 for recycling and reuse, and then the asphalt layer is laid on top of the water-stabilizing layer 1. At this time, the mesh stabilizing rod 304 can be fully combined with the asphalt layer to enhance the connection strength between the asphalt layer and the water-stabilizing layer 1.
