The invention relates to the technical field of rail traffic, in particular to a rail construction method with reserved turnout inserting and laying conditions, which comprises the following steps: constructing an under-rail ballast bed structure and a rail structure according to the requirements of a recent line, and constructing the under-rail ballast bed structure according to the requirements of a turnout ballast bed of a long-term line. A connector matched with a turnout is reserved in a sleeper base plate of the track structure. After the construction of the recent line is finished, opening the recent line for traffic; when the turnout needs to be inserted and laid in the long-term line, the existing steel rails and fasteners of the recent line are dismantled, and the turnout is inserted and laid through the reserved connectors. The method has the advantages that the work amount and the implementation risk of turnout inserting and laying can be greatly reduced, and the maintenance workload and the safety risk point cannot be increased even if only common lines are laid in the recent period; the structure is simple, reasonable, convenient to construct and suitable for popularization.
本发明涉及轨道交通技术领域，尤其是一种预留道岔插铺条件的轨道施工方法，按近期线路要求进行轨下道床结构以及轨道结构的施工，其中所述轨下道床结构按照远期线路的道岔道床要求进行施工，所述轨道结构的轨枕垫板预留有与道岔相适配的接口；当近期线路施工完毕后，进行近期线路的开通通车；当远期线路需要插铺道岔时，拆除近期线路的既有钢轨以及扣件，通过预留的所述接口插铺所述道岔。本发明的优点是：可以大幅减低道岔插铺的工程量和实施风险，近期只铺设普通线路也不会增加维护工作量和安全风险点；结构简单合理，施工方便，适于推广。
