Bridge head roadbed structure and construction method thereof
The invention discloses a bridgehead roadbed structure and a construction method thereof, and the bridgehead roadbed structure comprises: a cement soil compaction pile row arranged in a foundation; the cement mixing pile column is arranged in the foundation; a first geogrid layer is laid in the broken stone hardcore in a clamping manner; a trapezoidal supporting structure, a second geogrid layer and a shearing force limiting supporting structure are sequentially clamped and laid in the foundation bed bottom layer from bottom to top at intervals; the trapezoidal supporting structure comprises a plurality of trapezoidal frames, a reinforcing mesh and a concrete filling layer; the shearing force limiting supporting structure comprises a transverse base, a support, a fence, a bearing groove and a first trapezoidal protrusion. The beam span base comprises an abutting end and a second trapezoidal protrusion. And the pavement layer is paved at the top of the beam span and the top of the foundation bed bottom layer. The bridgehead roadbed structure can remarkably reduce the settlement speed of the roadbed at the bridgehead connecting position, is matched with bridge settlement and reduces the settlement difference.
本发明公开了一种桥头路基结构及其施工方法，包括：水泥土挤密桩列，布设于地基内；水泥搅拌桩列，布设于地基内；碎石垫层，其内夹铺有第一土工格栅层；基床底层，其内从下至上依次间隔夹铺有梯形支撑结构、第二土工格栅层及剪力限位支撑结构；梯形支撑结构包括：多个梯形架、钢筋网、混凝土填充层；剪力限位支撑结构包括：横向基座、支座、围挡、承接槽、第一梯形凸起；梁跨底座包括：抵接端、第二梯形凸起；路面层，其铺设于所述梁跨顶部和所述基床底层顶部。本发明的桥头路基结构可以显著减少桥头连接处路基的沉降速度，与桥梁沉降适配，减少沉降差异。
