Problems solved by technology

[0004] The purpose of the present invention is: in order to solve the problem of the existing separated roadbed, the slopes are placed separately, and the cross-section is two trapezoidal or inverted trapezoidal. Affected by the structure, water accumulation is easy to occur on the road surface, and gradually penetrates into the roadbed, and at the same time Vehicles in the process of driving will also exert a certain pressure on the road surface. Through the effect of force transmission, it is easy to cause subsidence or deformation of the subgrade, which seriously affects the service life of the subgrade and the structural integrity of the subgrade. A separate road subgrade is proposed and its construction method

Abstract

The invention discloses a separated highway subgrade and a construction method thereof and which belongs to the technical field of road engineering. The separated highway subgrade comprises a first-stage engineering subgrade, a second-stage engineering subgrade is arranged on the side of the first-stage engineering subgrade, combining devices are connected into the second-stage engineering subgrade and the first-stage engineering subgrade in an embedded manner, and stable base plates are laid at the tops of the second-stage engineering subgrade and the first-stage engineering subgrade. In thepresent invention, through mutual cooperation of the designed combination devices, a first waterproof layer, a second waterproof layer, a first buffer plate, a second buffer plate, the macromolecule easy plaster, the macromolecule polymer, the steel grillwork, a geotextile layer, a sand grain layer, a permeable pavement layer and a drainage pipe, the first-stage engineering subgrade and the second-stage engineering subgrade can be prevented from being damaged to a relatively high extent by laying the waterproof, noise-reducing and buffering structures, sedimentation and deformation of the first-stage engineering subgrade and the second-stage engineering subgrade are prevented, and the stability of the first-stage engineering subgrade and the second-stage engineering subgrade is improved.

Description

technical field [0001] The invention belongs to the technical field of road engineering, and in particular relates to a separated road subgrade and a construction method thereof. Background technique [0002] 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 to the depth of the foundation. On the longitudinal section, the roadbed must ensure the elevation required by the line; on the plane, the roadbed is connected with bridges and tunnels to form a complete and continuous line. In civil engineering, subgrade plays an important role in terms of construction quantity, floor area and ...
