Roadbed for controlling differential settlement of highway bridge transition section of expressway and construction method
The invention belongs to a roadbed for controlling differential settlement of a highway bridge transition section, the roadbed comprises a bridge abutment, a roadbed and a transition section, the lower side of the transition section is provided with a reinforcing pile, the upper surface of the transition section is provided with a roadbed surface layer, and the transition section comprises a foam concrete layer, an arched reinforcing layer and a reinforced concrete layer which are connected in sequence. The roadbed is a stepped slope, the horizontal section of the stepped slope of the roadbed is arched, an arched reinforcing layer is erected on the horizontal section of the stepped slope of the roadbed, the arched reinforcing layer is arranged in the foam concrete layer and divides the foam concrete layer, and the reinforced concrete layer is an inverted stepped slope, and the horizontal section of the inverted stepped slope of the reinforced concrete layer covers the end of the corresponding arched reinforcing layer. According to the roadbed, the differential settlement difference of the road and bridge transition section can be well reduced, the structure is stable, and construction is convenient.
本发明属于一种控制高速公路路桥过渡段不均匀沉降的路基，包括桥台、路基和过渡段，所述过渡段下侧设有加固桩，所述过渡段上表面设有路基表层，所述过渡段包括依次连接的泡沫混凝土层、拱形加固层和钢筋混凝土层，所述路基为阶梯状斜坡，且所述路基的阶梯状斜坡水平段为拱形，所述路基阶梯状斜坡水平段搭设有拱形加固层，所述拱形加固层设于泡沫混凝土层中，并将泡沫混凝土层分割，所述钢筋混凝土层为倒阶梯状斜坡，且所述钢筋混凝土层倒阶梯状斜坡的水平段将对应的拱形加固层末端覆盖，本发明能够良好的减少路桥过渡段不均匀沉降差，结构稳定，施工方便。
