An adapter structure and prefabricated construction method of underground continuous wall

The present invention discloses a joint structure and the method of construction of a prefabricated underground continuous wall, comprising a prefabricated structure and the underground continuous wall formed in the connector body preform structure underground continuous wall on both sides of the body, the connection structure comprising: a first connector structure disposed prefabricated underground continuous wall body first side, a first connecting structure comprises a pouring chamber and positioning slots extends further from the positioning slot toward the interior of preform underground continuous wall body; and a second connecting structure, provided preformed in underground continuous wall the second side of the body, the second connection structure comprises a shape adapted to the positioning strip card slot location. By providing a shape adapted to the positioning slots and positioning strips on both sides of the card prefabricated underground continuous wall body, respectively, when the article is positioned in the card body preform underground continuous wall inserted into the positioning slot, and positioning the positioning slot and card strip mesh with each other, limiting the horizontal movement of the main body preform underground continuous wall in the casting of the slurry, improve connection quality prefabricated underground continuous wall.
