Slotted hole structure system for reinforcing concrete diaphragm wall by penetrating through sludge layer and construction method
The invention provides a slotted hole structure system for reinforcing a concrete diaphragm wall by penetrating through a sludge layer and a construction method. The slotted hole structure system is composed of a plain soil platform, dry-method cement mixing piles and concrete guide walls; plain soil is filled on the two sides of the axis of a slotted hole in the axis direction of the concrete diaphragm wall to form the plain soil platform, and a construction platform is arranged on the side, where machines walk and work, of the plain soil platform; the dry-method cement mixing piles are arranged on the two sides of the slotted hole in the axis direction of the concrete diaphragm wall for reinforcement, and the bottoms of the dry-method cement mixing piles go deep into a stable soil layer; and the continuous concrete guide walls are constructed on the two sides of the slotted hole in the axis direction of the concrete diaphragm wall, the half, facing the slotted hole side, of a pile body of the dry-method cement mixing pile on each side is cut off downwards from the pile top to the height of the wall bottom of the corresponding concrete guide wall, formed notches are filled with the concrete guide walls, and the pile tops are embedded into the concrete guide walls. The slotted hole structure system is reliable in technology, economical, reasonable, low in construction difficulty, low in cost and good in effect.
本发明提供了一种穿越淤泥层加固混凝土防渗墙槽孔结构体系及施工方法，由素土平台、干法水泥土搅拌桩与混凝土导墙共同构成；沿混凝土防渗墙轴线方向在槽孔轴线两侧填筑素土形成素土平台，在素土平台于机械行走、作业的一侧设置施工平台；沿着混凝土防渗墙轴线方向在槽孔两侧设置干法水泥土搅拌桩加固，干法水泥土搅拌桩桩底深入至稳定土层以下；沿着混凝土防渗墙轴线方向在槽孔两侧施工连续的混凝土导墙，每侧的干法水泥土搅拌桩桩体朝向槽孔侧的一半自桩顶向下切除至混凝土导墙墙底高度处，形成的缺口由混凝土导墙填补，桩顶嵌入混凝土导墙内。本发明技术可靠、经济合理，施工难度小、成本低、效果好。
