Abstract

The invention discloses a highfill soil embankment slope protection structure and a construction method. The highfill soil embankment slope protection structure comprises an embankment, protection plates and a plurality of protection assemblies. Each protection assembly is formed by fixedly connecting a pull rod and an expansion nozzle. The ends, close to the slope of the embankment, of the protection assemblies are fixedly connected with the protection plates. Each expansion nozzle comprises a middle wire rod, expansion blades, force transmission blades and a sliding pipe. The expansion end of each middle wire rod is movably connected with the corresponding expansion blades in a hinged manner. Each middle wire rod is sleeved with the corresponding sliding pipe in a sliding manner. Each force transmission blade is connected between the corresponding sliding pipe and expansion blade. One end of each force transmission blade is hinged to the corresponding sliding pipe, and the other end of each force transmission blade is hinged to the corresponding expansion blade. The connecting end A of each middle wire rod is hinged to the connecting end B of the corresponding pull rod. The protection plate connecting end of each pull rod is correspondingly and fixedly connected with the corresponding protection plate. The highfill soil embankment slope protection structure and the construction method have the beneficial effects that the structure is simple, and construction is convenient; and the stability of the slope structure can be effectively enhanced, and good pavement performance can be achieved under the severe natural and traffic conditions.

Description

technical field [0001] The invention relates to the technical field of disaster prevention and reduction in road engineering, in particular to a high-fill soil embankment slope protection structure and a construction method. Background technique [0002] Since the beginning of the 21st century, my country's transportation infrastructure has made gratifying achievements, basically realizing "county-to-county expressways". In the process of expressway construction, due to the influence of terrain and linearity, it is not uncommon for highways to cross mountains and jump rivers. Embankments with high slopes in mountainous areas are often feared projects by design and construction units. In areas with poor engineering geology or areas with severe natural weather, high slope embankments often suffer from subsidence, erosion and other diseases, which may cause slope collapse accidents in severe cases. This has seriously affected the safety performance of road traffic, and it is a...
