Construction method of cover-excavation falling type prefabricated beam plate assembled subway station
The invention discloses a construction method for assembling a metro station through cover and excavation falling type precast beam plates, and belongs to the technical field of metro station construction. Falling type precast cross beams, precast block middle plates and precast block bottom plates are combined and spliced to form a beam plate structure, the overall structure of the metro station is assembled through precast components, the structural components are excellent in size and reliable in quality, and the construction efficiency is improved. The industrialization level of underground engineering is improved, the quality defects of pile foundation necking, reaming limit invasion, voids and pitted surfaces and the like of a cast-in-place pile enclosure structure are overcome, the problems of voids and pitted surfaces, chromatic aberration, cracks and the like of a cast-in-place concrete main body structure are solved, the overall prefabrication assembly of the station main body structure is realized, the maintenance waiting time of the cast-in-place structure is avoided, and the construction efficiency is improved. The construction progress is accelerated, the construction cost is reduced, the construction process is simplified, and the problems of long-time road sealing and occupying of open-cut station foundation pit construction, flying dust and noise generated by open-air construction and the like are solved.
本申请公开了一种盖挖降落式预制梁板装配地铁车站的施工方法，属于地铁车站施工技术领域，采用降落式预制横梁与预制分块中板、预制分块底板组合拼装成梁板结构，地铁车站整体结构采用预制构件装配，结构构件尺寸精良、质量可靠，提升了地下工程产业化水平，克服了钻孔灌注桩围护结构易产生桩基缩颈、扩孔侵限、蜂窝麻面等质量缺陷，避免了现浇混凝土主体结构易产生蜂窝麻面、色差、裂缝等问题，实现了车站主体结构的整体预制装配，避免了现浇结构养护等待时间，加快了施工进度，降低了施工成本，简化了施工工序，克服了明挖法车站基坑施工长时间封路占路，露天施工产生扬尘与噪声等问题。
