Specific embodiment
The application is not limited by following embodiments, can be determined according to the technical solution of the application and actual conditions specific
Embodiment.
As shown in Figures 1 to 6, the roadbed erosion control ruggedized construction that gabion wall 2 and groynes group close includes groynes, road shoulder barricade 1
With gabion wall 2；Road shoulder barricade 1 is located at river side and multiple groynes being spaced apart is distributed with, and the dam root end of groynes and road shoulder are kept off
Wall 1 is fixedly linked, and the abutment end of groynes is inclined to stretch to river；Gabion wall 2 is connected in the middle part of two adjacent groynes.
Groynes group is set on the outside of the road shoulder barricade 1 of highway, and by gabion wall 2 that the connection of adjacent groynes is integral, it will
Gabion wall 2, groynes group and road shoulder barricade 1 carry out build-in combination, form an enclosed region between composite structure, form firm water
Ruin safeguard structure；Due to the permeability flexible performance of gabion wall 2, can gradually deposit between road shoulder barricade 1 and gabion wall 2,
And then expand subgrade protection width, it is final to reduce current scour directly washing away and to the indirect broken of slope of highway to safeguard structure
It is bad, Highway risk is reduced, ensures the safe and smooth of highway.
The application embodies the advantage of three kinds of safeguard structures, has both accomplished the stable prevention and treatment composite structure of formation,
It protects water flow from washing away roadbed side slope well, avoids a series of harm of repetition damaged or destroyed by flood bring；The application protection against erosion
Significant effect is not easily susceptible to erosion damage, and has evaded and repeated the serious harm of damaged or destroyed by flood bring, while having also promoted river channel ecology
The balance and sustainable development of environment, ultimate guarantee highway transportation it is unimpeded and safe；It can guarantee long provoking flow spur dam certainly simultaneously
