Remediation structure for ballast track subgrade frost boiling and mud pumping and construction method of remediation structure for ballast track subgrade frost boiling and mud pumping
The invention belongs to the technical field of road engineering, and particularly relates to an improvement construction method and structure for ballast track roadbed frost boiling and mud pumping. The renovation construction method for ballast track subgrade frost boiling and mud pumping comprises the following steps that S1, a structure above a subgrade bed is dismantled, and the subgrade bed is excavated downwards; s2, carrying out original soil in-situ improvement on the surface layer of the subgrade bed, so that the original surface layer of the subgrade bed becomes a solidified layer with a certain thickness, and the water stability and rigidity of the surface layer of the subgrade bed are improved; s3, a water-resisting layer is laid on the curing layer; and S4, the structure is restored.
本发明属于道路工程技术领域，具体地，涉及一种有砟轨道路基翻浆冒泥的整治施工方法及结构。有砟轨道路基翻浆冒泥的整治施工方法包括以下步骤：S1，拆除基床上方的构筑物，并下挖至基床；S2，对所述基床的表层进行原土原位改良，使所述基床原来的表层成为具有一定厚度的固化层，提高路基表层的水稳定性和刚度；S3，在所述固化层上铺设隔水层；S4，复原所述构筑物。
