一种沉管隧道用止水带及其用于限制沉管拉合晃动的方法
摘要：
本发明公开了一种沉管隧道用止水带，包括具有基部体和顶部体的压胀主体、与压胀主体的基部体连接的底座、以及设在压胀主的顶部体顶部具有压胀弹性的止水棱，在顶部体顶部的止水棱两侧有对称设置的具有压胀弹性的晃控边；止水棱与两侧晃控边之间均有槽。本发明的优点是：有效限制了沉管在水底拉合过程中相邻两节沉管的端部在结合部的晃动幅度和晃动频率，提高了两节沉管之间的衔接精度；同时，还能适应强烈度地震导致的两沉管在结合部之间的大位移错位，且能够延长止水带的使用寿命。
摘要（英）：

The invention discloses a waterstop belt for an immersed tunnel. The waterstop belt comprises a dilatancy body with a base body and a top body, a base connected with the base body of the dilatancy body, and a waterstop edge arranged on the top of the dilatancy body and having dilatancy elasticity on the top, symmetrically-arranged shaking control sides with dilatancy elasticity are arranged on thetwo sides of the waterstop edge of the top of the top body, and grooves are formed between the waterstop edge and the shaking control sides on the two sides. The waterstop belt has the advantages that the shaking amplitude and the shaking frequency of ends of two adjacent sections of immersed tubes in the water bottom closing process of the immersed tubes can be effectively limited, the linking precision of two sections of immersed tubes is improved, meanwhile, the waterstop belt can adapt to large-displacement staggering of two sections of immersed tubes between the combination portions dueto the strong earthquake, and the service life of the waterstop belt can be prolonged.
