Construction method of urban rail transit slab ballast bed structure
The invention discloses a construction method of an urban rail transit slab ballast bed structure. The method comprises the steps of 1, constructing a rail foundation control network of a rail to be constructed, 2, constructing a rail foundation of the plate-type ballast bed area to be constructed, 3, measuring and setting out a rail center line control point of the to-be-constructed plate-type ballast bed area and rail slab mounting side lines of a plurality of rail slabs, 4, laying a plurality of geotextile isolation layers of the to-be-constructed plate-type ballast bed area, 5, binding a plurality of self-compacting concrete slab reinforcing meshes of the plate-type ballast bed area to be constructed, 6, laying a rail plate assembling layer of the to-be-constructed plate type ballast bed area, 7, pouring a plurality of self-compacting concrete slabs of the plate-type ballast bed area to be constructed, and 8, mounting steel rails and fasteners of the to-be-constructed plate type ballast bed area. According to the method, the fine adjustment precision of the rail plate can be improved, the assembly precision of the rail plate can be guaranteed, the forming quality of the self-compacting concrete plate can be improved by improving the grouting condition of the self-compacting concrete, and therefore the construction quality of a plate type turnout structure is improved.
本发明公开了一种城市轨道交通板式道床结构的施工方法，该方法包括：一、构建待施工轨道的轨道基础控制网；二、施工待施工板式道床区的轨道基础；三、测量放样待施工板式道床区的轨道中心线控制点和多个轨道板的轨道板安装边线；四、铺设待施工板式道床区的多个土工布隔离层；五、绑扎待施工板式道床区的多个自密实混凝土板钢筋网；六、铺设待施工板式道床区的轨道板拼装层；七、浇筑待施工板式道床区的多个自密实混凝土板；八、安装待施工板式道床区的钢轨和扣件。本发明能够提高轨道板的精调精度，能够保证轨道板的拼装精度，通过改善自密实混凝土的灌浆条件，能够提高自密实混凝土板的成型质量，从而提高板式道岔结构的施工质量。
