Arch shell rapid combination construction method for column-free station hall station
The invention discloses a rapid combination construction method for an arch shell of a non-column station hall station. The rapid combination construction method comprises the following steps that after a foundation pit is excavated, enclosure retaining walls, enclosure piles and construction piles are embedded; finishing a reinforced concrete structure of the pillow base; a station arch cover and short side wall permanent structure is formed; laying protection on the upper part of the arch shell; excavating from the road surface to the base; and protective laying of the base. The invention provides a new green design thought of'permanent and temporary integration 'for the subway station built by adopting the cover-excavation method, a temporary blanket structure system in the traditional cover-excavation method is combined with the arch shell top plate, the characteristics of good bending resistance, high rock stratum bearing capacity and the like of the arch shell structure are fully played while permanent and temporary integration is realized, and the construction cost is reduced. Upright post piles and side piles in a traditional cover excavation method are omitted, the cover excavation station hall is free of columns, large in space, wide in view and better in use function, and the method is clear in construction procedure, easy to operate and high in practicability under the rock stratum condition and has good social benefits and generalizability.
本发明公开了一种无柱站厅车站的拱壳快速组合施工方法，包括以下步骤：基坑开挖后围护挡墙、围护桩以及施作桩的嵌入；完成枕座钢筋混凝土结构；形成车站拱盖及短边墙永久结构；拱壳上部的防护铺设；路面至基底的开挖；基底的防护铺设。本发明为采用盖挖法修建的地铁车站提供了一种“永临合一”的绿色设计新思路，它将传统的盖挖法中的临时铺盖结构体系与拱壳顶板相结合，实现永临合一的同时，充分发挥拱壳结构抗弯性能好、岩质地层承载力高等特点，取消传统盖挖法中的立柱桩及边桩，实现盖挖车站站厅无柱大空间，视野开阔，使用功能更好，本发明施工工序明确，操作简单，在岩质地层条件下可实施性较强，具有较好的社会效益和可推广性。
