Prefabricated stand column inspection tunnel bed construction method
The invention relates to the field of ballast bed construction tool equipment, in particular to a prefabricated stand column inspection pit ballast bed construction method which comprises the steps that a storage frame is arranged in a foundation pit to vertically support a prefabricated stand column, and a center support is arranged in the foundation pit to transversely support the prefabricated stand column. Vertical connecting steel bars are pre-embedded in a foundation pit, a storage frame is taken out after a rail row is erected, reserved steel bars and the vertical connecting steel bars are welded after a rail is finely adjusted, and then the prefabricated stand column inspection pit bed is formed through the steps of cast-in-place concrete. The prefabricated stand column is in a non-fixed state during track installation and fine adjustment, the situation that the installation precision of the prefabricated stand column influences the installation precision of the track is avoided, and the installation precision of the prefabricated stand column and the installation precision of the track can be met at the same time; prefabricated stand column fixing and ballast bed forming are carried out synchronously, the construction efficiency is improved, meanwhile, the storage rack and the center support can be recycled, and the construction cost of an inspection pit bed can be reduced.
本发明涉及道床施工工装设备领域，特别涉及一种预制立柱检查坑道床施工方法，包括在基坑内设置存放架竖向支撑预制立柱的步骤和在基坑内设置中心支架横向支撑预制立柱的步骤，所述预制立柱底部设置预留钢筋，所述基坑预埋竖向连接钢筋，通过在轨排架设完成后取出存放架，在轨道精调后进行预留钢筋与竖向连接钢筋焊接，再通过现浇混凝土的步骤，实现预制立柱检查坑道床成型。使轨道安装和精调时预制立柱处于非固定状态，避免了预制立柱的安装精度影响轨道安装精度，能够同时满足预制立柱的安装精度和轨道的安装精度；预制立柱固定与道床成型的同步进行，提高了施工效率，同时，存放架和中心支架能够循环使用，有利于降低检查坑道床施工成本。
