Reservation method of cover-excavation top-down subway station side wall steel bar joint
The invention discloses a reserving method for a cover-excavation top-down subway station side wall steel bar connector. The reserving method comprises the following steps that (1) earth excavation is conducted; (2) construction of a coiled material waterproof structure; (3) a side wall floor mold and a middle plate bottom mold are constructed; (4) according to the sequence, structure connecting horizontal bars are implanted into the inner side of the diaphragm wall, side wall vertical bars are arranged, side wall downward extending connector horizontal bars are bound, middle plate steel bars are bound, side wall upper leading wall horizontal bars are bound, waterproof structures corresponding to the middle plates are constructed at the bar implanting positions, the side wall vertical bars are steel bars with the same length as the floor height, and the side wall vertical bars are steel bars with the same length as the floor height; the lower end is connected with a straight thread sleeve which is buried and fixed in fine sand, and the upper end is connected with an upper-layer reserved joint; (5) concrete is poured; (6) excavating a lower-layer soil body, and removing the mold; and a side wall steel bar joint exposed below the side wall downward extending joint is formed below the middle plate. The side wall reinforcing steel bar position precision is high, waterproof joints are few, the construction quality can be guaranteed conveniently, and the construction period can be shortened.
本发明公开了一种盖挖逆作法地铁车站侧墙钢筋接头的预留方法，采用以下步骤：1)土方开挖；2)卷材防水结构施工；3)施工侧墙地模和中板底模；4)按照顺序在地连墙内侧植入结构连接水平筋、设置侧墙竖筋、绑扎侧墙下伸接头水平筋、绑扎中板钢筋、绑扎侧墙上引墙水平筋，在植筋位置处施工对应中板的防水结构，侧墙竖筋采用长度与层高相同的钢筋，下端连接有直螺纹套筒埋固在细砂内、上端与上层预留接头连接；5)浇筑混凝土；6)进行下层土体开挖、拆模；在中板的下方形成有曝露在侧墙下伸接头下方的侧墙钢筋接头。本发明侧墙钢筋位置精度高，防水接缝少，便于保证施工质量，能够节约工期。
