Underground shear wall three-section type water stop bolt hole waterproof plugging structure and method
The underground shear wall three-section type water stop bolt hole waterproof plugging structure comprises a formwork lateral supporting system and structural concrete, a formwork fixing bolt is arranged in a hole in the structural concrete, and a water stop steel sheet is arranged in the middle of the formwork fixing bolt; the ends of the bolts are in bolted connection with the turnover templates; the end part of the turnover template bolt is connected with a bolt end buckle; brushing an anti-rust sealing agent on the end of the bolt and pouring end sealing concrete; and a BAC self-adhesive waterproof coiled material patch is adopted for pasting and plugging. According to the method, the end of the water stop bolt is protected through rust-proof treatment, corrosion and expansion of the water stop bolt due to long-term action of underground water are avoided, the water locking effect of the BAC self-adhesion waterproof coiled material patch on micro-expansion waterproof end plugging concrete is used for replacing traditional wet operation maintenance, the situation that the water stop bolt and water passing cracks are eroded by the underground water under the pressure effect is avoided, and the service life of the water stop bolt is prolonged. And the waterproofness and durability of the structure main body are improved, and the underground overall construction efficiency is improved.
本发明公开了一种地下剪力墙三段式止水螺栓孔洞防水封堵构造及方法，包括模板侧向支撑体系和结构混凝土，结构混凝土上的孔洞内设有固定模板螺栓，固定模板螺栓的中部设有止水钢片；螺栓端头与可周转模板螺栓连接；在可周转模板螺栓的端部连接螺栓端头卡扣；在螺栓端头上涂刷防锈封闭剂和浇筑端头封堵混凝土；并采用BAC自粘防水卷材贴片进行粘贴封堵。本发明利用防锈处理对止水螺栓端头进行保护，避免地下水长期作用止水螺栓锈蚀膨胀，利用BAC自粘防水卷材贴片对微膨胀防水的端头封堵混凝土的锁水作用代替传统湿作业养护，避免地下水在压力作用下侵蚀止水螺栓及过水裂隙，提升了结构主体的防水性及耐久性，加快了地下整体施工效率。
