Small-radius curve tramcar seamed line ballast track laying method
The invention discloses a small-radius curve tramcar seamed line ballast track laying method, and relates to the field of tramcar track laying construction.The method includes the steps that the line shape of a fixed line is adjusted firstly, then ballast feeding and track finishing are conducted, the traditional ballast feeding and track finishing construction sequence is changed, and small-radius curve line track lifting and line shape adjusting are conducted before ballast feeding and tamping; when the track is laid, the sleepers are densely arranged at the joints of the steel rails, and concrete buttresses are additionally arranged beside the sleepers to fix the sleepers, so that the bending stress of the steel rails is counteracted, the line shape of the small-radius curve line and the elevation control precision of the track are ensured, and the laying of the small-radius curve tramcar seamed line ballast track is realized; after construction, the whole small-radius curve ballast loading track can meet the line operation condition at a time, and smooth and safe driving is ensured.
本发明公开了小半径曲线有轨电车有缝线路有砟轨道铺设方法，涉及涉及有轨电车轨道铺设施工领域，该方法通过先调整固定线路线形，再上砟整道改变传统的上砟整道施工顺序，将小半径曲线线路起道与线形调整放在上砟捣固以前，并在轨道铺设时，在钢轨接头位置加密布置轨枕，并在轨枕旁增加混凝土支墩固定轨枕，以抵消钢轨自身的弯曲应力，确保小半径曲线线路线形及轨道标高控制精度，实现小半径曲线有轨电车有缝线路有砟轨道铺设，施工后小半径曲线上砟整道能一次性达到线路运行条件，确保行车平顺与安全。
