Light replacement roadbed and abutment transition section structure and differential settlement control method thereof
The invention discloses a light change-filling roadbed and abutment transition section structure which comprises a change-filling pond slag layer, a geogrid, an EPS block body and a reinforced concrete cover plate, and the EPS block body sequentially transits from multiple layers to one layer step by step from the abutment; the replacing and filling pond slag layer is correspondingly arranged at the bottom of the EPS block body, replacing and filling pond slag with corresponding depths step by step according to different layering thicknesses of the EPS block body, and performing layering and compacting; the geogrid is arranged in the replacement and filling pond slag layer according to different replacement and filling depths of the replacement and filling pond slag; and the reinforced concrete cover plate is arranged on the top layer of the EPS block body layer. According to the light replacement roadbed and abutment transition section structure, the load can be further diffused, and differential settlement of the road and bridge transition section is further reduced. The technical structure is simple, operation is convenient, safety and reliability are achieved, and construction efficiency is high. The method can be popularized and applied in corresponding fields as a general structure and method.
本发明公开了一种轻质换填路基与桥台过渡段结构，包括换填塘渣层、土工格栅、EPS块体和钢筋混凝土盖板，其中，所述EPS块体自桥台处依次从多层逐级过渡为1层；所述换填塘渣层对应设置于EPS块体底部，根据EPS块体分层厚度不同，逐级换填相应深度的换填塘渣，并分层压实；所述土工格栅根据换填塘渣换填深度不同，布置于换填塘渣层内部；所述钢筋混凝土盖板，设置于EPS块体层顶部一层。本发明的轻质换填路基与桥台过渡段结构，能进一步扩散荷载，进一步降低路桥过渡段差异沉降。该技术结构简单、操作方便、安全可靠、施工效率高。可作为一种通用结构及方法在相应领域推广应用。
