Repair and reinforce road shoulders and slopes. (1) The road shoulder is an important structure that ensures the overall stability of the roadbed and eliminates road water. The maintenance of the road shoulder is directly related to the maintenance, repair and reinforcement of the road shoulder. During the maintenance work, the road shoulder is required to have a moderate cross slope (the cross slope is smaller than the road surface). The camber is 1% to 2% larger) and the edges are straight; the surface is smooth, clean, and free of debris; it must be free of ruts, grooves, bulges, subsidences, and gaps; the slope must be stable, smooth, without gullies, and the size must be in compliance with regulations. In addition, shoulders and slopes should be in harmony with the environment and made as aesthetically pleasing as possible. (2) Dredge, improve and pave the drainage system. Drainage facilities such as side ditches, intercepting ditches, drainage ditches, and underground ditches (pipes) should be promptly cleared of blockages and the water flow should be directed to ensure that there are no tall grass and no obstructions; the longitudinal slope is moderate, the water flow is smooth, and the entrance and exit are good, etc. , and comprehensively consider paving and reinforcement based on topography, soil quality, flow rate and other conditions. (3) Maintain and repair various structures and manage and protect the land on both sides of the highway. The protective structures along both sides of the highway include slope protection, protective walls, gabions, tree planting, turfing, and various types of retaining walls. It is required to ensure that these structures are intact and play their role in protecting and reinforcing the roadbed. (4) Observe, prevent, and deal with landslides, mudslides, mudslides, collapses, collapses, and other roadbed diseases, promptly check various roadbed dangers and fill in water damage reports, and repair damaged sections such as mudslides and other damaged roads in a timely manner to restore them as soon as possible to shorten the traffic blocking time as much as possible . (5) Plan to partially widen and heighten the roadbed, improve sharp bends, steep slopes and sight distances, and gradually improve its technical standards.
