Prefabricated assembling periodic structure for track base and construction method of structure
The invention discloses a prefabricated assembling periodic structure for a track base. The structure comprises base units (1), base ditches (2), connecting beams (3) between the base units and steel bars or embedded steel plates (4), the base units are arranged in the base ditches, the base units are connected through the connecting beams between the base units, a trackbed plate is installed above the upper surface, self-compacting concrete is arranged below the lower surface, the base units are longitudinally arranged along the center line of a line, the distance and the length between the base units can be adjusted according to application occasions, and reinforcing steel bars or embedded steel plates extending out of the structure are reserved at the bottoms of the base units, and can be fixedly connected to reinforcing steel bars of the adjusting layer formed by the lower self-compacting concrete. The invention further provides a corresponding construction method, the base is of a prefabricated structure, the quality is easy to control, the construction period is shortened, the ditch size is large, blockage is not prone to occurring, steel bars and concrete are greatly saved, and environment friendliness is achieved.
本发明提供了一种用于轨道基底的预制拼装周期结构，包括：基底单元(1)，基底水沟(2)、基底单元间的连梁(3)以及钢筋或预埋钢板(4)，其中基底单元设置在基底水沟内，基底单元为多个，通过基底单元间的连梁进行连接，上表面上方安装道床板，下表面下方为自密实混凝土，基底单元沿着线路中心线纵向布置，每块基底单元之间的间距和长度可视应用场合进行调整，基底单元的底部预留延伸至结构外的钢筋或者预埋钢板，可与下部自密实混凝土形成的调整层的钢筋进行连接固定。还提供了对应的施工方法，基底采用预制结构，质量容易控制，缩短施工周期，水沟尺寸大，不易堵塞，极大节省钢筋、混凝土用量并且绿色环保。
