Technical Field
[0001] The utility model relates to the technical field of subgrade reinforcement, in particular to a subgrade reinforcement structure. Background Art
[0002] The subgrade is the foundation of the track or road surface, which is a geotechnical structure formed by excavation or filling. The main function of the subgrade is to provide necessary conditions for the laying of the track or road surface and the operation of trains or vehicles, and to bear the static and dynamic loads of the track and rolling stock or the road surface and traffic loads, and at the same time transfer and disperse the loads deep into the foundation. In the longitudinal section, the subgrade must ensure the elevation required by the line; in the plane, the subgrade is connected with bridges and tunnels to form a complete and continuous line. In civil engineering, the subgrade occupies an important position in terms of construction quantity, floor area and investment. The subgrade body includes embankments filled with natural soil and stone and cuttings excavated in natural strata. It directly supports the track and bears the train loads passing through the track, which is the main body of the subgrade. According to different geological conditions and filling materials, the subgrade body can be divided into six basic forms: embankment, cutting, half embankment, half cutting, half embankment and half cutting, and non-fill and non-excavation subgrade.
[0003] The subgrade reinforcement structure is a structure for reinforcing the subgrade to enhance the overall strength of the subgrade. At present, most construction workers usually pour concrete on both sides of the subgrade for reinforcement during the construction of the subgrade, but there is no reinforcement equipment inside the subgrade. Therefore, when large trucks drive for a long time, it is easy to cause the subgrade to collapse and damage the road surface. For this reason, a subgrade reinforcement structure is proposed.
[0004] Therefore, it is necessary to provide a new subgrade reinforcement structure to solve the above technical problems. Summary of the Utility Model

Plugging holes are formed on both the roadbed and the base. The traction bars are fixedly installed inside the plugging holes. The reinforcement plate is fixedly installed on one side of the roadbed through the traction bars.
[0008] Preferably, a guiding groove is formed at the junction of the base and the roadbed, and a protective plate is cast on the inner wall of the guiding groove.
