Construction method of high-speed railway assembly type polyurethane curing ballast bed
The invention discloses a construction method of a high-speed railway assembly type polyurethane curing ballast bed, the method comprises the following steps: setting out sleeper control side lines, marking sleeper spacing control lines and installing a track panel group, lifting and supporting the track panel group, installing a support frame and coarsely adjusting the track panel group, installing an assembly type polyurethane curing ballast bed template, performing assembly type polyurethane curing ballast bed track panel group fine adjustment, assembly type polyurethane curing ballast bed track panel group fixing, assembly type polyurethane curing ballast bed adjusting layer construction, retesting, track panel frame and supporting frame dismounting, assembly type polyurethane curing ballast bed steel rail and fastener mounting, railway ballast backfilling and finished product protection. The high-speed railway assembly type polyurethane curing is obtained. The track skeleton frame and the supporting frame are combined, adjustment is convenient, the polyurethane curing sleepers are directly prefabricated, installation is convenient, the concrete adjusting layer is poured at a time, the ballast bed quality is guaranteed, and the ballast bed is suitable for construction of assembly type polyurethane curing ballast beds of roadbeds, bridges and tunnels in high-speed railways.
本发明公开了一种高速铁路装配式聚氨酯固化道床的施工方法，该方法包括：放样轨枕控制边线，划线标注轨枕间距控制线及轨排组安装，轨排组起升及支撑，安设支撑架和粗调轨排组，装配式聚氨酯固化道床模板安装，装配式聚氨酯固化道床轨排组精调，装配式聚氨酯固化道床轨排组固定，装配式聚氨酯固化道床调整层施工，复测，拆除轨排框架和支撑架，安装装配式聚氨酯固化道床的钢轨和扣件，回填道砟和成品保护，得到高速铁路装配式聚氨酯固化道床。本发明通过将轨排框架和支撑架相结合，调整方便，通过直接预制聚氨酯固化轨枕，安装方便，通过将混凝土调整层一次浇筑完成，保证了道床质量，适用于高速铁路中路基、桥梁、隧道装配式聚氨酯固化道床施工。
