Multi-layer expressway structure and construction method thereof
The invention discloses a multi-layer expressway structure and a construction method thereof, and relates to the field of highway construction. The structure comprises an embankment, a roadbed and a road surface, wherein the cross sections of the embankment and the roadbed are trapezoidal, the cross section of the road surface is grooved, road shoulders are built on two sides of the road surface and comprise a hard road shoulder and an earth road shoulder from inside to outside, side ditches are built on the outer sides of the earth road shoulder, the drainage gradient of each side ditch is 5%-8%, and drainage ditches are formed in the outer sides of the side ditches; side slopes are built on the two sides of the embankment, the two sides of the roadbed and the two sides of the road surface correspondingly, and reinforced nets are arranged on the outer sides of the side slopes correspondingly; a middle belt is arranged on the road surface; the embankment sequentially comprises a lowerembankment and an upper embankment, the roadbed sequentially comprises a lower roadbed and an upper roadbed, and the road surface sequentially comprises a subbase layer, a base layer and a surface layer. The expressway is stable in structure and large in bearing capacity, and the service life of the expressway is prolonged. Meanwhile, the drainage structure is low in manufacturing cost and easy toconstruct, and corrosion of rainwater to side slopes is reduced.
本发明公开了一种多层式高速公路结构及其施工方法，涉及公路施工领域，该结构包括路堤、路床和路面；所述路堤和路床的横断面呈梯形修筑，所述路面的横断面呈槽式修筑，所述路面的两侧修筑有路肩，从内到外包括硬路肩和土路肩，所述土路肩的外侧修筑有边沟，所述边沟的排水坡度均为5%~8%，所述边沟的外侧设有排水沟；所述路堤、路床和路面的两侧均修筑有边坡，所述边坡的外侧均设置有加筋网；所述路面的上面设置有中间带；所述路堤依次包括下路堤和上路堤，所述路床依次包括下路床和上路床，所述路面依次包括底基层、基层和面层。该高速公路结构稳定且承载力大，增加了高速公路的使用年限，同时排水结构造价低，且容易施工，减少了雨水对边坡的侵蚀。
