Mountainous area highway cantilever roadbed and using method thereof

Abstract

The invention discloses a mountainous area highway cantilever roadbed and a using method thereof. The mountainous area highway cantilever roadbed comprises an anchoring section, a roadbed cantilever beam and pavement slabs, wherein the anchoring section is arranged at a slope toe of a side slope on the inner side of an original highway, a groove is formed in the anchoring section, and one end of the roadbed cantilever beam is fixedly embedded in the groove of the anchoring section; the roadbed cantilever beam is placed above an original highway and extends in the horizontal direction of the end, which is away from an inner side slope, of the original highway; the roadbed cantilever beam is in a horizontal parallel state with the original highway; the pavement slabs are laid on the surfaceof the roadbed cantilever beam, rapid standardized construction can be conducted on newly-built, modified and expanded road sections in narrow areas of mountainous areas through the prefabricated cantilever roadbed beams and the pavement slabs, and the problems of high manufacturing cost and large construction risk caused by traditional retaining wall arrangement and slope excavation are solved.

Description

technical field [0001] The invention relates to the technical field of building structures, in particular to a cantilevered subgrade of a mountain road and a method for using the same. Background technique [0002] At present, in the new construction, reconstruction and expansion of traditional mountainous roads, the terrain is poor or the width of the original roadbed is insufficient, and the roadbed retaining wall is often used to support the embankment. However, the use of such a support method will greatly increase the construction area and cost of the project. The workload of the construction workers is reduced, and the construction efficiency is reduced; if the slope on the inner side of the road is brushed and the slope is excavated, the construction risk will be increased, and the construction area and cost of the project will also be increased, which will increase the cost of the construction workers. The workload reduces the problem of construction efficiency. Co...
