Construction method of subway station cast-in-place concrete side wall large steel formwork supporting system
The invention relates to a construction method of a subway station cast-in-place concrete side wall large steel formwork supporting system, which comprises the following steps of: pouring bottom plate concrete, and binding a side wall reinforcement cage by means of a side wall base; bearing beams and longitudinal limiting grooves are laid on the bottom plate at intervals, and vertical jacks are arranged on the bearing beams; a hydraulic rod is arranged in the foundation pit in a supporting mode, and a large steel mold panel abuts against the top face; and side wall concrete is poured. The method has the beneficial effects that a vertical and horizontal high-precision adjustment large steel mold construction technology is researched and developed, and high-precision adjustment of the large steel mold is realized by arranging a bearing beam and sliding beam structure and utilizing a longitudinal jack and a transverse jack; three corresponding hydraulic rod arrangement methods are provided for the situation that a foundation pit inner support and a reverse top plate exist on the large steel die and neither the foundation pit inner support nor the reverse top plate exists on the large steel die, the large steel die panel can be shored and fixed under various conditions, and the anti-floating effect is further improved.
本发明涉及一种地铁车站现浇混凝土侧墙大钢模支模体系的施工方法，包括以下步骤：浇筑底板混凝土，依托侧墙基座绑扎侧墙钢筋笼；在底板上间隔铺装垫梁和纵向限位槽，垫梁上设置竖向千斤顶；吊装大钢模，基坑内支撑设置液压杆大钢模面板抵在顶面；浇筑侧墙混凝土。本发明的有益效果是：研发了纵横向高精度调整大钢模施工技术，通过设置垫梁及滑梁结构，利用纵向千斤顶及横向千斤顶实现大钢模的高精度调整；针对大钢模上存在基坑内支撑、存在逆做顶板和既不存在基坑内支撑又不存在逆做顶板提出了三种对应的液压杆设置方法，实现在多种情况下均能对大钢模面板进行顶撑固定，进一步提升了抗浮效果。
