Double-side widening and easing structure of small-radius curve road section, road section and method

SHANG ZHAOJUAN

According to the double-side widening and easing structure for the small-radius curve road section, the linear smooth widening earth shoulder edge line and the widening traffic lane edge line are arranged on the inner side and the outer side of the original earth shoulder edge line and the original traffic lane edge line of the original road respectively; single-side high slope excavation, high fill protection work and demolition amount can be effectively reduced during construction; the bilateral widening easing road section comprises the bilateral widening easing structure, can better adapt to small-radius curve roads and regions with many buildings in the center of an urban area, and is more beneficial to driving safety and comfort; the double-side widening method provided by the invention is used for obtaining the double-side widening relaxation structure. The double-side widening and easing structure of the small-radius curve road section, the road section and the method are used for solving the problems that in the prior art, due to the fact that the small-radius curve road is widened on the inner side, the project investment scale is large, the project construction difficulty is large, and the construction quality cannot be guaranteed.

本申请提供的一种小半径曲线路段的双侧加宽缓和结构，通过在原始道路的原土路肩边缘线以及原行车道边缘线的内外两侧分别设置线性平顺加宽土路肩边缘线以及加宽行车道边缘线，使得施工时能有效减少单侧高边坡开挖和高填方防护工作以及拆迁量；本申请提供的一种双侧加宽缓和路段包括了所述双侧加宽缓和结构，能够更好的适应小半径曲线道路以及市区中心建筑物多的地域，更有利于行车安全和舒适；本申请提供的一种双侧加宽方法用于获得所述双侧加宽缓和结构。本申请提供的一种小半径曲线路段的双侧加宽缓和结构、路段以及方法用于解决现有技术中通过内侧加宽小半径曲线道路导致的工程投资规模大、项目施工难度大以及施工质量无法保证的问题。
