Integrated construction method for accessory structure of subway open cut station
The invention relates to an integrated construction method for an accessory structure of a subway open cut station, which is used for large stations such as a station hall shared by two lines of an urban subway or connected with an inter-city station, and the requirement for station entering space is properly increased, so that the accessory structure of the subway station is integrally designed; during construction, it needs to be considered that longitudinal connection holing of a station accessory structure and a station hall layer main body structure relates to sharing of a top beam of an enclosure structure within the range of connection holing of the integrated accessory structure and the main body structure and construction and dismantling of cast-in-place concrete piles and hanging net shotcrete anchors; after the construction of the station main body structure is completed, during secondary construction of an accessory structure, waterproof construction of a construction joint and a deformation joint within the connection holing range of the main body structure is carried out; and in the connection holing range, the auxiliary bottom plate structure reserves a post-cast strip, supports are replaced, and secondary pouring is conducted in a skip mode. The station accessory structure integrated construction method provided by the invention can well solve the construction problem of large-space connection when the subway station accessory structure enters the station.
本发明涉及一种地铁明挖车站附属结构一体化施工方法，其用于城市地铁两线共用车站站厅或与城际车站接驳等大型车站，对进站空间需求适当加大，从而对地铁车站附属结构一体化设计，施工时需考虑车站附属结构与站厅层主体结构纵向接驳开洞涉及一体化附属结构与主体结构接驳开洞范围内围护结构冠梁的共用，混凝土灌注桩和挂网喷锚的施作与拆除；车站主体结构施工完成后，二次施工附属结构时，与主体结构接驳开洞范围内施工缝和变形缝的防水施作；以及接驳开洞范围内，附属底板结构预留后浇带，换撑、跳仓二次浇筑等复杂工序的施工方法。本发明提供的车站附属结构一体化施工方法能够很好地解决地铁车站附属结构进站大空间开接驳的施工问题。
