Light prefabricated ballast bed and construction method
The invention discloses a light prefabricated ballast bed which comprises two prefabricated longitudinal sleepers, the two prefabricated longitudinal sleepers are longitudinally distributed at intervals, a pressure bearing table is arranged on the tops of the prefabricated longitudinal sleepers, a steel rail is installed on the pressure bearing table through fasteners, a first layer of connecting reinforcing mesh is embedded in the bottoms of the prefabricated longitudinal sleepers. The two first-layer connecting reinforcing meshes are connected through a second-layer connecting reinforcing mesh which is transversely distributed, a plurality of transverse through holes are transversely formed in the prefabricated longitudinal sleepers, third-layer connecting reinforcing meshes are installed in the two corresponding transverse through holes, concrete is poured in a gap between the two prefabricated longitudinal sleepers, and a base layer is formed; the base layer covers the first layer of connecting reinforcing mesh, the second layer of connecting reinforcing mesh and the third layer of connecting reinforcing mesh. The invention further discloses a construction method of the light prefabricated ballast bed. The light prefabricated ballast bed has the beneficial effects that overall installation of the light prefabricated track bed is achieved, and in the installation process, the prefabricated longitudinal sleepers are convenient to install through the large supporting frame.
本发明公开了轻型化预制道床，包括预制纵向轨枕，预制纵向轨枕为两个，且两个预制纵向轨枕呈纵向间隔分布，预制纵向轨枕的顶部设有承压台，承压台上通过扣件安装有钢轨，预制纵向轨枕的底部预埋有第一层连接钢筋网，两第一层连接钢筋网通过横向分布的第二层连接钢筋网连接，预制纵向轨枕上横向开设有若干横向贯穿孔，两对应的横向贯穿孔内安装有第三层连接钢筋网，两预制纵向轨枕之间的缝隙处浇筑混凝土并形成基底层，基底层覆盖第一层连接钢筋网、第二层连接钢筋网和第三层连接钢筋网，还公开了轻型化预制道床的施工方法。本发明的有益效果是：实现了轻型化预制道床的整体安装，且在安装过程中，通过支撑大架使得预制纵向轨枕安装方便。
