Ballastless track roadbed slab construction method
The invention relates to a ballastless track roadbed slab construction method. The method comprises the following steps: S1, surveying and setting out; s2, binding reinforcing steel bars; s3, track panel assembly is conducted, sleeper separation is conducted by means of an automatic sleeper separation platform, rails are installed on sleepers to form track panels, and the track panels are transferred to a paving area through a track panel lifting appliance; s4, track panel coarse laying; s5, formwork installation is conducted, specifically, side formworks and expansion joint partition plates are installed, ground anchors are driven into the ground on the outer sides of the side formworks, and formwork side supporting devices and formwork buckling devices are installed so that the side formworks can be fixed; s6, track panel fine adjustment is conducted, specifically, the track panel is subjected to fine adjustment by means of ballastless track automatic fine adjustment equipment; s7, pouring concrete; and S8, concrete curing. According to the side formwork supporting structure, the occupied space of the side formwork supporting structure can be greatly reduced by arranging the formwork side supporting device and the formwork buckling device, efficient paving of the track panel and the turnover efficiency of all construction equipment can be achieved only through the track panel lifting tools of different sizes, the construction efficiency is greatly improved, and the construction cost is controlled.
本申请涉及一种无砟轨道道床板施工方法，其包括：S1.测量放线；S2.钢筋绑扎；S3.轨排组装，借助自动分枕平台进行分枕，并在轨枕上安装铁轨形成轨排，以轨排吊具将轨排转移至铺装区域；S4.轨排粗铺；S5.模板安装，安装侧模板和伸缩缝隔板，在侧模板外侧地面打入地脚锚钉，并安装模板侧撑装置和模板上扣装置，以对侧模板进行固定；S6.轨排精调，借助无砟轨道自动精调设备对轨排进行精调；S7.混凝土浇筑；S8.混凝土养护。本申请通过设置模板侧撑装置和模板上扣装置可以极大缩减侧模板支撑结构的占地空间，仅通过本申请的多个尺寸不同的轨排吊具就可实现轨排的高效铺装以及各施工设备的周转效率，极大提高了施工效率，控制了施工成本。
