Environmental-friendly grass concrete highway slope protection structure and construction method thereof

Abstract

The invention relates to an environmental-friendly grass concrete highway slope protection structure which mainly comprises grass concrete, prefabricated framed girders, anchor rods, soil nails, a mortar flag stone wall, a hillslope drainage system and a gravity retaining wall. The soil nails are arranged in an unstable rock mass of an original highway slope. Concrete piers are arranged at anchor heads. The mortar flag stone wall is additionally arranged on an original hillslope. The interior of the mortar flag stone wall is sequentially filled with a gravel bed, a clay bed and the grass concrete from bottom to top. The prefabricated framed girders are mounted at the top of the mortar flag stone wall. The anchor rods are arranged at the intersections of the prefabricated framed girders. Concrete inclusions are arranged at the peripheries of the anchor rods. The hillslope drainage system is arranged in the gravel bed. A drainage channel is arranged at a slope bottom. The gravity retaining wall is arranged on the outer side of a highway subgrade side ditch at a slope foot. The environmental-friendly grass concrete highway slope protection structure is high in integrality and stability, and combines safety embankment with environment protection really, and the traffic environment is effectively improved. The invention further provides a construction method of the environmental-friendly grass concrete highway slope protection structure.

Description

technical field [0001] The invention relates to an environment-friendly grass-planting concrete road slope protection structure and a construction method, which belong to the field of road engineering and are suitable for road slope protection projects in rainy areas with high requirements for greening and stability. Background technique [0002] The side slope protection of the road is the main technical measure to provide safety guarantee for the stability of the roadbed and the reliable service life of the road. The traditional road slope protection can be mainly divided into dry masonry, mortar masonry, concrete frame, plate rigid material protection, or turf vegetation protection. Of these types of protective construction, the former is at the cost of destroying land resources, making the road slope gray and white, which is extremely inconsistent with the natural landscape, causing new environmental pollution; while the latter has a steeper slope, which is prone to runo...

Problems solved by technology

Of these types of protective construction, the former, at the cost of destroying land resources, makes the road slope gray and white, which is extremely inconsistent with the natural landscape and causes new environmental pollution; while the latter has a steeper slope, which is prone to runoff erosion due to rainfall. It is also difficult to meet the ideal shielding requirements
