Underground diaphragm wall newly-added hole waterproof structure and construction method
The invention discloses a construction method for a waterproof structure of a newly-added hole of an underground diaphragm wall and the waterproof structure, and relates to underground diaphragm walls. The construction method specifically comprises the following steps that S1, a hole with the hole diameter larger than the diameter of a sleeve is formed in the underground diaphragm wall; s2, the casing pipe is welded and fixed to a steel bar exposed due to hole opening in the underground diaphragm wall; s3, formworks are erected on the inner side and the outer side of the hole opening position of the underground diaphragm wall, the redundant hole opening space inside the hole and outside the casing pipe is closed, and the two ends of the casing pipe penetrate through the formworks; s4, slurry is poured into the closed space in the S3; s5, the shaped steel plate is fixed to the underground diaphragm wall through anchor bolts and structural adhesive; in the invention, the sleeve and the shaped steel plate are fully welded, and the steel pipe and the original structure are poured by adopting grouting materials and epoxy resin, so that the integrity is ensured, meanwhile, a good water stop effect is brought, new and old structures are firmly connected, the construction speed is high, and the cost is saved; not only is the structural safety of the post-added hole ensured, but also the problem that the post-added sleeve is easy to leak water is effectively solved.
本发明公开了一种地下连续墙新增洞口防水结构的施工方法及防水结构，涉及地下连续墙，具体包括以下步骤，S1：在地下连续墙上开设孔径大于套管直径的孔洞；S2：将套管与地下连续墙内因开孔裸露的钢筋焊接固定；S3：于地下连续墙开孔处内外两侧搭设模板，将孔洞以内、套管以外的多余开孔空间封闭，并使套管两端穿过模板；S4：向S3中的封闭空间内浇筑浆料；S5：将定型钢板通过锚固螺栓和结构胶固定于地下连续墙上；本发明中，套管与定型钢板满焊，钢管与原结构间采用灌浆料+环氧树脂浇筑，整体性得以保证，同时带来良好的止水效果，新老结构连接的牢固，施工速度快，节约成本；既保证了后增洞口的结构安全，又有效解决了后增套管易漏水的难题。
