The invention discloses a prefabricated connector, a manufacturing method and an underground diaphragm wall butt joint method. Comprising a connector body (1), the cross section of the connector body (1) is of a symmetrical I-shaped structure, two water stop steel plates (2) which are symmetrical to each other and extend outwards are arranged on the longitudinal section of the middle of the connector body (1), and outwards-extending butt joint steel bars (3) and steel boxes (4) which are aligned in the longitudinal direction are arranged on the two end faces of the connector body (1) respectively. The end face of the connector body (1) is further covered with a sawtooth steel base plate (6) with sawteeth facing outwards. The construction period of the underground diaphragm wall can be greatly shortened. 本发明公开了一种预制接头、制作方法及地下连续墙对接方法。包括接头主体(1)，接头主体(1)的横截面呈对称"工"字型结构，接头主体(1)在其中部纵截面上设置有两片相互对称的、向外伸出的止水钢板(2)，接头主体(1)的两端面上分别设有沿纵向对齐的外伸对接钢筋(3)和钢盒子(4)；接头主体(1)的端面上还覆盖有锯齿朝外的锯齿钢垫板(6)。本发明能大幅缩短地下连续墙的施工工期。
