Construction method of urban rail transit plate-type turnout structure
The invention discloses a construction method of an urban rail transit plate-type turnout structure. The method comprises the steps of 1, constructing a rail foundation control network of a rail to beconstructed, 2, chiseling a rail foundation of a to-be-constructed plate type turnout zone, 3, measuring and setting out a rail center line control point of the to-be-constructed plate type turnout zone and turnout plate mounting sidelines of a plurality of turnout plates, 4, binding a plurality of self-compacting concrete plate reinforcing meshes of the to-be-constructed plate-type turnout zone,5, paving a turnout plate assembling layer of the plate type turnout zone to be constructed, 6, pouring a plurality of self-compacting concrete plates of the to-be-constructed plate-type turnout zone, and 7, mounting turnout steel rails and fasteners of the to-be-constructed plate type turnout zone. By means of the method, the fine adjustment precision of the turnout plate can be greatly improved, the assembly precision of the turnout plate can be guaranteed, meanwhile, 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岔结构的施工方法，该方法包括：一、构建待施工轨道的轨道基础控制网；二、凿毛待施工板式道岔区的轨道基础；三、测量放样待施工板式道岔区的轨道中心线控制点和多个道岔板的道岔板安装边线；四、绑扎待施工板式道岔区的多个自密实混凝土板钢筋网；五、铺设待施工板式道岔区的道岔板拼装层；六、浇筑待施工板式道岔区的多个自密实混凝土板；七、安装待施工板式道岔区的道岔钢轨和扣件。本发明能够大大提高道岔板的精调精度，能够保证道岔板的拼装精度，同时，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。
