Reserved construction method for passage underneath passing urban railway subgrade
The invention provides a construction method for reserving a channel underneath passing through a city railway subgrade, which comprises the following steps of: carrying out permanent slope excavation on a city railway road mat, and finishing permanent slope protection construction; a riding track is arranged in the direction of a railway mat in a pulling mode, fender posts are arranged at the pre-excavation position, and a temporary foundation pit of a reserved underpass is excavated; laying a waterproof material at the bottom of the foundation pit, binding steel bars of a frame bridge of the underpass, and pouring concrete of a bottom plate and a top plate of the underpass; steel bar connectors are reserved at the end opening parts of the two sides of the underpass frame bridge, closing of the opening parts is completed, and then a waterproof layer is arranged; the foundation pit is backfilled to the elevation of the permanent slope toe platform; and filling a roadbed structure to complete construction of ancillary facilities. When the railway bed is constructed, the underpass for planning the municipal road is reserved and is protected, conditions are created for connection of the planned road in the later period, and meanwhile operation of urban railways cannot be affected by connection construction in the later period.
本发明提供一种下穿市域铁路路基的通道预留施工方法，包括如下步骤：对市域铁路路垫进行永久边坡开挖，并完成永久边坡护坡施工；沿铁路路垫方向拉设马道，在预开挖位置设置围护桩，开挖预留下穿道的临时基坑；在基坑底部敷设防水材料，绑扎下穿道框架桥钢筋，并浇筑下穿道的底板和顶板混凝土；在下穿道框架桥两侧的端口部预留钢筋接驳器，并完成口部的封闭，然后设置防水；对基坑进行回填，回填至永久边坡坡脚平台标高；填筑路基结构，完成附属设施建设。在铁路路基施工的同时预留好规划市政道路的下穿道，并对其进行保护处理，为后期规划道路的接驳创造条件，同时后期接驳施工不会影响市域铁路的运营。
