Subway station and accessory main body structure interface construction method
The invention discloses a construction method for a connector of a subway station and an accessory main body structure. The construction method comprises the following steps that earthwork is excavated between a main body structure cast-in-situ bored pile and an accessory structure cast-in-situ bored pile; a bracket connected with the main body structure cast-in-situ bored pile is constructed in the construction space; an accessory structure bottom plate is constructed, the accessory structure bottom plate is connected with the bracket, and a post-cast strip located above the bracket is reserved on the accessory structure bottom plate; part of the supporting beams and part of the main body structure cast-in-situ bored piles above the brackets are dismantled, and latticed columns are arranged in vacant parts of the main body structure cast-in-situ bored piles to support the suspended main body structure crown beams; the post-cast strip and the corresponding part of the latticed column are integrally poured with concrete; and after the post-cast strip concrete reaches the preset strength, the latticed columns located outside the concrete are cut off. According to the scheme, the construction procedure of temporary connection between the station main body structure and the accessory structure can be reduced, and the construction period is effectively shortened.
本申请公开了一种地铁车站与附属主体结构接口施工方法，其包括如下步骤：在主体结构钻孔灌注桩及附属结构钻孔灌注桩之间开挖土方；在施工空间内施工与主体结构钻孔灌注桩连接的牛腿；附属结构底板施工，附属结构底板与牛腿连接，且附属结构底板上预留有位于牛腿上方的后浇带；拆除部分支撑梁及牛腿以上的部分主体结构钻孔灌注桩，并在主体结构钻孔灌注桩的空缺部设置格构柱以支撑悬空的主体结构冠梁；后浇带与对应的部分格构柱一体浇筑混凝土；后浇带混凝土达到预定强度后切除位于混凝土外的格构柱。本申请具有因此本方案能够减少车站主体结构和附属结构之间临时连接的施工工序，有效缩短施工周期的效果。
