Pier abutment roadbed structure and construction method
The invention discloses a pier abutment roadbed structure. The pier abutment roadbed structure comprises an abutment body poured on a bearing platform. A steel plate pile perpendicular to the abutment body is arranged between the abutment body and a roadbed soil body. The roadbed soil body comprises a road surface structural layer, cement rubble layers and a cement concrete layer. According to a construction method, a hole is downwards dug so that the steel plate pile can be vertically inserted in the hole, and the steel plate pile is arranged in the abutment body or/and the bearing platform. The construction method further comprises the steps that the roadbed soil body is laid, firstly mortar mixing and grinding are carried out on an original ground, then the cement concrete layer and one or more cement rubble layers are sequentially laid and repeatedly ground, and finally the road surface structural layer is laid. By means of steel plate pile protection, structural layers and materials different from those of a traditional roadbed soil body are combined, the adverse effect on the stability of a pier abutment due to repeated grinding in the actual construction process is avoided, and the roadbed soil body can be rapidly and safely constructed. The method also has the beneficial effects of being easy to construct and operate, high in efficiency and the like.
