Deviation-rectifying roadbed structure of high-speed railway in goaf site and construction method
The invention relates to a deviation-rectifying roadbed structure of a high-speed railway in a goaf site. The deviation-rectifying roadbed structure comprises bridge abutments, a deviation-rectifying bearing platform, a graded broken stone hardcore, a roadbed filler, a pressure-resistant arched beam and an asphalt waterproof layer, and is characterized in that the deviation-rectifying bearing platform is positioned between the two bridge abutments and is connected with the bridge abutments through the pressure-resistant arched beam; the roadbed filler wraps the upper end surfaces of the bridge abutments and the upper end face of the deviation-rectifying bearing platform, and the asphalt waterproof layer wraps the upper end face of the roadbed filler. The construction method comprises the six steps of bridge abutment construction, prefabricated part construction, deviation-rectifying transfer platform construction, compression-resistant arched girder construction, road laying and settlement deviation rectifying and the like. The construction number of the pile foundation piers can be reduced, the roadbed construction cost can be reduced, adverse effects caused by differential settlement of a foundation can be eliminated, and a certain deformation resistance is achieved; and when large residual settlement occurs in the goaf foundation, the deformation quantity can be accurately monitored and judged, and accurate deviation correction and adjustment operation can be carried out on the settlement deformation quantity.
本发明涉及一种采空区场地高速铁路可纠偏路基结构，包括桥台、可纠偏转承平台、级配碎石垫层、路基填料、抗压拱梁、沥青防水层，可纠偏转承平台位于两个桥台之间，可纠偏转承平台通过抗压拱梁与桥台连接，路基填料包覆在桥台、可纠偏转承平台上端面，沥青防水层包覆在路基填料上端面的。其施工方法包括建设桥台，预制件构建，可纠偏转承平台建设，抗压拱梁施工，道路铺设及沉降纠偏等六个步骤。本发明可以降低桩基桥墩的建设数量，减少路基建设成本造价，可以消除地基不均匀沉降造成的不良影响，具有一定的抗变形能力；并在采空区地基出现大的剩余沉降时，能够精确监测和判断形变量，并可实现对沉降形变量进行精确纠偏调节作业。
