Construction method for dismounting concrete support of fabricated subway station
The invention relates to the technical field of pile support system fabricated station construction, in particular to a construction method for dismounting a concrete support of a fabricated subway station. The method comprises the following steps that a plurality of fixing bottom plate blocks are hoisted in sequence, and the bottom plate blocks are tensioned and locked in the depth direction; base grouting, fertilizer tank backfilling and inverted arch backfilling are carried out; grouping is carried out according to a plurality of steel supports corresponding to the lower portion of a firstconcrete support, and the concrete supports and the steel supports are divided into a plurality of groups in the depth direction; and side wall blocks, middle plate blocks and top plate blocks are sequentially assembled in the groups in the depth advancing direction, temporary supports are additionally arranged in the construction advancing direction, and the steel supports and the concrete supports in the groups are dismounted. By means of the construction method, dismounting of the concrete supports is synchronously achieved in the foundation pit and roadway propelling construction process,the original concrete supports and the original steel supports can be dismounted step by step when the bottom plate blocks, the side wall blocks, the top plate blocks and the like are assembled, a dismounting process is simple in technology, the efficiency is higher, and the safety and reliability are achieved.
本发明涉及桩撑体系装配式车站施工技术领域，尤其涉及一种用于装配式地铁车站混凝土支撑拆除的施工方法，包括：依次吊装若干固定底板块，将底板块在纵深方向上张拉锁紧；进行基底注浆、肥槽回填和仰拱回填；按照第一道混凝土支撑下方对应若干道钢支撑进行分组，将混凝土支撑和钢支撑在进深方向分成多组；在按照进深推进方向在组内依次拼装侧墙块、中板块和顶板块，在施工前进方向增设临时支撑并拆除组内的钢支撑和混凝土支撑。通过该本发明公开的施工方法，在进行基坑和巷道推进施工的过程中同步实现混凝土支撑的拆除，在进行底板块、侧墙块、顶板块等的拼装时可逐步拆除原先的混凝土支撑和钢支撑，拆除过程工艺简单，效率更高，也更安全可靠。
