Technical Field

[0001] The utility model relates to the technical field of road engineering, in particular to a crack-resistant roadbed and pavement structure. Background Art

[0002] The roadbed and pavement structure is an important part of the highway, which is directly related to the highway's bearing capacity and service life. As the foundation of the highway, the roadbed supports the pavement structure and bears the erosion of traffic loads and natural factors. The pavement directly bears the impact of traffic loads and natural climate, and is usually composed of the surface layer, base layer and subbase layer (or cushion layer).

[0003] The existing roadbed is made of concrete, and the road surface is paved on the roadbed surface with asphalt. However, there is a lack of corresponding stable connection structure between the road surface and the roadbed, and the connection stability between the roadbed and the road surface is poor, which makes the roadbed and the road surface prone to cracking during use, thereby affecting the service life of the roadbed and the road surface and driving safety.

[0004] Therefore, a crack-resistant roadbed and pavement structure is proposed. Utility Model Content

[0005] The utility model aims to provide a crack-resistant roadbed and pavement structure.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A crack-resistant roadbed pavement structure, comprising:

[0008] Grassroots;

[0009] A concrete frame is poured on the top of the base layer;

[0010] The concrete frame is in a field shape, and the interior of the concrete frame is divided into four small cells, and the four small cells are used to fill the concrete fixing layer;

[0011] The top of the concrete frame is paved with an asphalt surface layer;

[0012] Reinforcement columns are provided inside the four small cells, and contact area enlargement strips are connected to the outer walls of the reinforcement columns;

[0015] The concrete column is located inside the connecting hole.

[0016] Preferably, the reinforcement columns and contact area enlargement strips are located inside the concrete fixed layer.

[0017] Preferably, the contact area increasing plates and contact area increasing columns are located inside the asphalt surface layer.

[0018] Preferably, the outer wall of the reinforcement column is provided with a mounting groove, and the contact area enlargement strip is installed inside the mounting groove;

[0019] The top of the reinforcement column is provided with an empty slot, the bottom of the empty slot is provided with a threaded hole, and the top of the contact area enlargement strip is provided with a clamping hole;

[0020] A threaded rod is threadedly connected to the threaded hole, a rotating shaft is fixed to the top of the threaded rod, and the bottom of the threaded rod is clamped in the clamping hole.

[0021] Preferably, a first through slot and a second through slot are formed on the top of the contact area enlarged plate, and a first connecting strip and a second connecting strip respectively passing through the first through slot and the second through slot are fixed on the top of the reinforcement column;

[0022] A connecting block located between the first connecting strip and the second connecting strip is fixed on the top of the contact area enlarged plate;

[0023] The first connecting strip, the second connecting strip and the outer wall of the connecting block are respectively provided with a first fixing hole, a second fixing hole and a third fixing hole;

[0024] The first fixing hole, the second fixing hole and the third fixing hole are provided with screw threads;

[0025] A limiting plate is fixed at one end of the threaded member, and an outer wall of the threaded member is threadedly connected to a limiting ring, wherein the limiting plate abuts against the second connecting strip, and the limiting ring abuts against the first connecting strip.

[0026] Compared with the prior art, the beneficial effects of the utility model are:

[0027] Since a contact area increasing plate is connected to the top of the reinforcement column, a contact area increasing column is fixed on the top of the contact area increasing plate, and reinforcement columns are provided inside the four small grids, and contact area increasing strips are connected to the outer walls of the reinforcement columns, the contact area between the asphalt surface layer and the concrete fixed layer can be increased with the cooperation of the reinforcement columns and the contact area increasing strips, and the contact area between the asphalt surface layer and the base layer can be indirectly increased. Similarly, with the cooperation of the contact area increasing plate and the contact area increasing column, the contact area between the asphalt surface layer and the base layer is further indirectly increased. In summary, compared with the existing ones, the utility model increases the contact area between the asphalt surface layer and the base layer, thereby improving the connection stability between the asphalt surface layer and the base layer, so that the asphalt surface layer and the base layer are not easy to crack during use, thereby improving the service life and driving safety of the asphalt surface layer and the base layer.

[0028] The utility model places the contact area enlarged strip in the installation groove, and then rotates the rotating shaft, which drives the threaded rod to move in the threaded hole. When one end of the threaded rod is clamped into the inside of the clamping hole, the contact area enlarged strip and the reinforcement column can be connected and fixed. The threaded component is placed in the first fixing hole, the second fixing hole, and the third fixing hole, and then the limiting ring is threadedly connected to the outer wall of the threaded component. After the limiting plate abuts against the second connecting strip and the limiting ring abuts against the first connecting strip, the contact area enlarged plate can be fixed to the top of the reinforcement column. Therefore, the utility model is convenient for assembling parts, thereby improving the efficiency of road engineering construction. BRIEF DESCRIPTION OF THE DRAWINGS
