Strengthening Structure and Construction Method of Highway Subgrade

Abstract

The invention discloses a road subgrade reinforcement structure and a construction method, comprising a soil base, a road subgrade body is arranged above the soil base; a storage slot, the storage slot is arranged on the upper end of the soil base; a reinforcement seat, the reinforcement seat is arranged at The inside of the storage slot; the roadbed protective plate, the roadbed protective plate is arranged on both sides of the road subgrade body, the first hinge seat is arranged between the two roadbed protective plates and the reinforcing seat, and the first hinge seat and the reinforcing seat are Through screw connection, the first hinge seat is rotatably connected with the roadbed protection plate. The realization can play a role in reinforcing the side end of the roadbed, thereby inhibiting the expansion of the side end of the roadbed under force to the outside, effectively avoiding the landslide of the roadbed, improving the reinforcement effect, making the use more stable and improving the safety of use.

Description

technical field [0001] The invention relates to the technical field of roadbed reinforcement, in particular to a roadbed reinforcement structure and a construction method. Background technique [0002] Highways are roads that connect cities, villages, and industrial and mining bases, built in accordance with national technical standards, and approved by the highway authority. The road does not contain fields or trails naturally formed in the countryside. It is mainly used for cars and has Certain technical standards and facilities. The subgrade is the foundation of the track or road surface, and it is a geotechnical structure formed after excavation or filling. The main function of the subgrade is to provide the necessary conditions for the laying of the track or road surface and the operation of trains or trains, 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 spread the load t...

AI Technical Summary

Problems solved by technology

[0003]At present, the roadbed reinforcement structure is mainly achieved by replacing the foundation material or pouring. This method has a poor reinforcement effect on the side of the roadbed. After a period of use , as the load capacity increases, it is prone to cracking and may also cause subsidence and landslides, which will greatly increase the potential safety hazards and greatly increase the subsequent maintenance costs. The use effect is not good and cannot meet the use requirements.
