Novel hard shoulder pavement structure suitable for highway excavation section roadbed drainage
The invention discloses a novel hard shoulder pavement structure suitable for highway excavation section roadbed drainage, which comprises a prefabricated shallow-dish-shaped shoulder, the prefabricated shallow-dish-shaped shoulder is a cuboid concrete prefabricated part, the top of the prefabricated shallow-dish-shaped shoulder is provided with a shallow-dish-shaped groove, and the shallow-dish-shaped groove penetrates through the cuboid concrete prefabricated part in the length direction; the circular arc is in smooth transition in the width direction, extends towards the upper parts of the two sides, and forms a horizontal section when being close to the two sides of the cuboid concrete prefabricated part; the shallow dish-shaped grooves are used for collecting road surface accumulated water, guiding and draining roadbed cutting slope drained water and draining the drained water in the length direction; the multiple prefabricated shallow-dish-shaped road shoulders are sequentially arranged side by side in the length direction, and the multiple shallow-dish-shaped grooves are communicated in the length direction to form a continuous accumulated water drainage channel. By using the hard shoulder pavement structure, the land acquisition area and the slope excavation earth and stone volume are reduced, the drainage problem of the excavation roadbed of the expressway in the limited space range of the road width of the expressway is solved, and the manufacturing cost can also be saved.
本发明公开了一种适用于高速公路挖方段路基排水的新型硬路肩路面结构，包括预制浅碟型路肩，预制浅碟型路肩为一长方体混凝土预制件，其顶部开设有一浅碟形凹槽，浅碟形凹槽在长度方向上贯通长方体混凝土预制件，在宽度方向上为光滑过度、并向两侧上方延伸的圆弧，且在接近长方体混凝土预制件的两侧时成水平段；浅碟形凹槽用于汇集路面积水、引排路基路堑边坡排水，并沿长度方向排放；预制浅碟型路肩为多个，沿长度方向依次并列排布，多个浅碟形凹槽在长度方向上相贯通，形成连续的积水排水通道。使用该硬路肩路面结构减少征地面积及边坡开挖土石方量，解决了在高速公路路幅宽度有限空间范围内的高速公路挖方路基排水问题，也能节省造价。
