Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of geogrid, especially to a geogrid for road construction. BACKGROUND

[0002] In road construction, the application principle of geogrid mainly includes reinforcement, stress dispersion and isolation effect. It fixes soil particles together through friction between geogrid and soil particles to form an integral structure, thereby improving the bearing capacity of subgrade. At the same time, geogrid can also disperse the upper load to a wider range, reduce local stress concentration and reduce the deformation and settlement of subgrade. In addition, geogrid can also separate soil layers with different properties to prevent mixing and penetration between different soil layers and maintain the stability of subgrade.

[0003] A geogrid for road construction is disclosed in Chinese patent (authorized publication number CN220598019U). The first ground fixing nail and the second ground fixing nail are inserted into the interior of the soil respectively, which improves the grip of the geogrid in different soils and ensures that the device is more stable during use. Not only can it purify water flow and reduce soil pollution, but also can make the water flow out smoothly and avoid internal flow accumulation to reduce the service life of the highway.

[0004] For the above and existing related technologies, the inventors believe that the following defects often exist: the existing lap joint method only relies on the friction and adhesion of the geogrid material itself, which is difficult to resist large tension; although the sewing method enhances the connection strength to a certain extent, the sewing line itself may become a stress concentration point and is prone to breakage under long-term load. UTILITY MODEL CONTENTS

[0005] The technical problem to be solved by the utility model is that the fracture at the connection in the prior art not only reduces the overall mechanical properties of the geogrid, but also affects the reinforcement effect on the soil. Therefore, we propose a geogrid for road construction.

[0006] In order to achieve the above purpose, the following technical scheme is adopted in the present application: a geogrid for road construction, comprising a geogrid body, a plurality of fastening mechanisms are mounted on the surface of the geogrid body, a through slot is formed in the inside of the fastening mechanism, an upper subgrade layer is arranged at the bottom of the geogrid body, an intermediate layer is arranged at the bottom of the upper subgrade layer, a lower subgrade layer is arranged at the bottom of the intermediate layer, and a foundation layer is arranged at the bottom of the lower subgrade layer.

[0007] Preferably, anti-skid grooves are arranged at both ends of the fastening mechanism.

[0008] Preferably, the material of the upper subgrade layer is polyethylene.

[0009] Preferably, the material of the intermediate layer is polyester fiber.

[0010] Preferably, the material of the lower subgrade layer is polyester plastic.

[0011] Preferably, the material of the base layer is high-strength steel wire fiber.

[0012] The technical effects and advantages of the present application are as follows:

[0013] In the present application, the geogrid body is provided with a plurality of fastening mechanisms at the connection position, so that the geogrid body can be more stable during use and is not prone to displacement or deformation. The insertion slot in the fastening mechanism facilitates the connection with the adjacent geogrid body or other road structure components, thereby enhancing the stability and firmness of the overall structure.
