Mountainous area high-speed foam light soil roadbed structure

Abstract

The invention discloses a mountainous area high-speed foam light soil roadbed structure and belongs to the technical field of roadbed slope construction. The roadbed structure comprises a step, wherein a retaining wall extending downwards is arranged at an end of a lowest stage of the step, a concrete base is arranged on the retaining wall, a prefabricated panel is arranged on the concrete base, foam light soil is poured between the prefabricated panel and the step, the prefabricated panel comprises a plurality of concrete panels, a plurality of concrete panels are piled up to form a wall surface, embedded rings are arranged on every two adjacent concrete panels respectively, ends, away from the concrete panels, of every two adjacent embedded rings are connected through a connecting steelbar, one end of a pull rod is fixedly connected with one connecting steel bar, and the other end of the pull rod is fixedly connected with the other adjacent connecting steel bar. The roadbed structure is advantaged in that an angle steel stand column penetrates through the concrete base and the retaining wall and is vertically arranged on a slope roadbed, an inner wall of the bent position of thepull rod is fixedly connected with the angle steel stand column, land occupation due to road sloping can be reduced, a demolition project is effectively reduced, and land acquisition and demolition cost is reduced.

Description

【Technical Field】 [0001] The invention relates to the technical field of roadbed side slope construction, in particular to a high-speed foam light soil roadbed structure in mountainous areas. 【Background technique】 [0002] In the roadbed construction, with the late start of my country’s expressways, the social economy has continued to develop rapidly in recent years, and expressway traffic has increased rapidly. Some expressways built in the early stages have reached or exceeded the designed capacity. The reconstruction and expansion of expressways will become a new hot spot for expressway construction in the next ten years. my country's land resources are relatively scarce, and there are dense buildings near roads, making demolition difficult and costly. [0003] When the roadbed is relatively steep, anti-slide piles or counter-weight shoulder walls are generally used, but the use of anti-slide piles and counter-weight shoulder walls has high construction costs, longer construct...
