Subway prefabricated stand column type inspection pit structure and construction method
The invention belongs to the technical field of urban rail transit, and particularly provides a subway prefabricated stand column type inspection pit structure and a construction method. The subway prefabricated stand column type inspection pit structure comprises short sleeper blocks, prefabricated stand columns and fasteners; a plurality of prefabricated stand columns are arranged at intervals along the extending direction of steel rails, and foundation pits positioned on two sides of an inspection pit are filled with the short sleeper blocks; the plurality of short sleeper blocks are connected with the steel rails through the fasteners according to preset intervals to form track panels; the track panels are hoisted and roughly paved into the foundation pits on two sides of the inspection pit, reinforcement cages around the track panels are bound, and a formwork is erected; the geometrical shape and position states of the short sleeper blocks are adjusted so as to adjust the steel rails to be in a preset state, and then concrete is poured to enable the short sleeper blocks and the foundation pits to be fixed into a whole; after the strength of the concrete reaches a preset condition, the formwork is dismounted, the fasteners and the steel rails are dismounted, and the prefabricated stand columns are installed on the short sleeper blocks; and the steel rails are installed at the top ends of the prefabricated stand columns through the fasteners. The construction efficiency and quality are improved, the construction period is shortened, and the labor intensity is reduced.
本发明属于城市轨道交通技术领域,具体提供了一种地铁预制装配立柱式检查坑结构及施工方法,包括短轨枕块、预制立柱及扣件,多个预制立柱沿钢轨的延伸方向间隔设置,短轨枕块填充于位于检查坑两侧的基坑内。通过扣件将多个短轨枕块按照预设间距以此与钢轨连接形成轨排;将轨排吊装粗铺到检查坑两侧的基坑内,绑扎轨排周围钢筋笼并立模;调节短轨枕块的几何形位状态以调整钢轨至预设状态,然后浇筑混凝土使得短轨枕块与基坑固定成一个整体;当混凝土强度达到预设条件后,拆模、拆除扣件和钢轨,并在短轨枕块上安装预制立柱;通过扣件将钢轨安装至预制立柱的顶端。提高了施工效率和质量、缩短了施工周期,降低劳动强度。
