Anti-slip roadbed structure

Abstract

The invention discloses an anti-slip roadbed structure. The anti-slip roadbed structure comprises a base roadbed layer and a base plate, wherein the base plate is arranged above the middle of the base roadbed layer; each of both sides of the base plate is respectively provided with a protective plate in a fixed manner; a first concrete layer, a second concrete layer and an asphalt layer are sequentially laid from bottom to top between the two protective plates above the base plate; multiple longitudinal reinforcements parallel to the protective plates are laid along the length direction of a road in the first concrete layer; multiple transverse reinforcements perpendicular to the protective plates are laid along the length direction of the road in the second concrete layer; the outer side of each protective plate is fixedly provided with a reinforcing angle plate positioned on the upper surface of the base roadbed layer; the outer side of the reinforcing angle plate is provided with an isolating layer fixed on the upper surface of the base roadbed layer; and a permeable layer for covering the reinforcing angle plate is filled between the protective plate and the isolating layer. The anti-slip roadbed structure is reasonable in structural arrangement, effectively improves the road carrying capacity, can relieve burdens of drainage facilities, and is less prone to damage and rupture.

Description

technical field [0001] The invention relates to the technical field of roadbed construction, in particular to an anti-slip roadbed structure. Background technique [0002] Subgrade is the basic building under the railway track or road surface. In order to ensure the quality of the line and prevent disasters, it is necessary to study the basic laws of the strength and stability of the subgrade, and formulate scientific technical standards, technical specifications and process requirements for all aspects of subgrade design, construction and maintenance. Subgrade refers to the belt-shaped structure built according to the location of the route and certain technical requirements as the foundation of the road surface. It is the foundation of railways and highways. The subgrade is a linear structure built with soil or stone. The subgrade built under good geological, hydrological and climatic conditions. In terms of materials, roadbeds can be divided into three types: soil roadbe...

Problems solved by technology

[0003] In the construction of roads in mountainous areas, most roads have to be built on winding mountains, and some projects have steep slopes on both sides. Usually, a large amount of slope excavation is required to form a roadbed to lay the road surface. If there is heavy traffic equipment passing through, or it is washed by heavy rain, it is very easy to landslide and collapse, and the road surface is damaged
