Description

Technical Field

[0001] The utility model relates to the technical field of roadbed slope protection engineering, in particular to an antifreeze arched skeleton slope protection combining prefabrication and cast-in-place. Background Art

[0002] Exposed high and steep slopes have large catchment areas, fast water flow, and strong scouring ability. At the same time, they lack soil conditions for plant growth, and the slopes are prone to collapse and landslides. The protection of mine slopes, road slopes, and roadbed slopes has always attracted much attention. Therefore, it is necessary to select appropriate protection forms based on the characteristics of the slope's geological and environmental conditions, slope height, and slope side pressure.

[0003] Skeleton slope protection refers to a frame structure formed by concrete or mortar-laid flagstones on the roadbed slopes of highways and railways. Grass is planted in the middle of the frame to prevent the roadbed slope from sliding and collapsing. It is a component of the roadbed and a protective project for the roadbed. Traditional concrete arched skeleton slope protection requires formwork and formwork, and the construction process is cumbersome, slow, and has a long cycle. At the same time, as an outdoor project, it has poor frost resistance and a short lifespan. It cannot play a long-term role in protecting the roadbed, causing the roadbed to slide and collapse and endanger the road. Summary of the invention

[0004] The utility model aims to provide a prefabricated and cast-in-place antifreeze arched frame slope protection according to the above-mentioned deficiencies of the prior art. A prefabricated arched frame and a ceramsite concrete layer are arranged on the slope surface of the roadbed, and the prefabricated arched frame is embedded in an arched frame groove pre-excavated on the slope surface. The prefabricated arched frame becomes a template for the slope casting area, and ceramsite concrete is cast to form a ceramsite concrete layer. The prefabricated arched frame, the ceramsite concrete layer and the slope surface form a whole. The prefabricated arched frame can not only be customized and mass-produced, but also can become a slope casting template, saving the template cost. At the same time, the ceramsite concrete layer is not only light in weight, but also has good frost resistance and a long service life, and can protect the roadbed for a long time, and prevent the roadbed from sliding and collapsing and endangering the road.
