The invention belongs to the technical field of foundations of deep foundation pit engineering, and particularly discloses an anti-seepage method for connection of a dock gallery expansion joint waterstop and a steel sheet pile dock wall, which comprises the following steps: transforming a rubber waterstop according to construction requirements; welding enclosure is conducted between the rubber waterstop and the steel sheet pile, so that a closed concrete pouring area is formed between the rubber waterstop and the steel sheet pile; as for the area where the rubber water stop belt is not completely attached to the steel plate on the steel plate pile, delayed coagulation type water swelling paste is smeared at the locking opening position for blocking, a transverse steel plate is welded for fixing, and the two sides are pasted through sticky steel glue, so that a closed water stop system is formed in the junction area; therefore, underground water of the gallery bottom plate and accumulated water in the gallery are prevented from forming a seepage channel. The method is low in cost, good in water stopping effect and easy to popularize, and the influence of seepage on the durability of the gallery is reduced to a certain extent.

    本发明属于深基坑工程的基础技术领域,具体公开了船坞廊道伸缩缝止水带与钢板桩坞壁连接的防渗方法,包括步骤:根据施工要求对橡胶止水带进行改造;在橡胶止水带与钢板桩之间进行焊接围护,使橡胶止水带与钢板桩之间形成一个封闭的混凝土浇筑区域;对于橡胶止水带与钢板桩上的钢板未能完全贴合的区域,在锁口位置涂抹缓凝型遇水膨胀膏进行封堵,并焊接横向钢板进行固定,两侧用粘钢胶进行粘贴,使其交界区域形成闭合的止水体系,以防止廊道底板的地下水与廊道内的积水形成渗流通道。本发明成本较低,止水效果良好,在一定程度上减少了渗流对廊道的耐久性影响,易于推广。
