The invention discloses an underground diaphragm wall joint and a construction method thereof. The underground diaphragm wall joint is obtained after construction through the construction method of the underground diaphragm wall joint and is applied to a wall body of an underground diaphragm wall, a reinforcement cage is arranged in the wall body, the reinforcement cage is filled with first concrete, and the underground diaphragm wall joint comprises a water stop joint plate arranged in the wall body, a rubber sleeve is arranged in the water stop joint plate, the rubber sleeve is installed on the inner wall of the water stop joint plate, and the rubber sleeve is filled with second concrete. According to the underground diaphragm wall joint, after the reinforcement cage and the water stop joint plate are placed in a groove formed in guide wall construction, concrete is poured to form the wall body, a through hole is formed in the water stop joint plate, the water stop joint plate is filled with the rubber sleeve with the second concrete, and the rubber sleeve is tightly attached to the inner wall of the water stop joint plate, the water stop joint plate is sealed, an aim of water stop and seepage prevention is achieved, the underground diaphragm wall joint is reasonable in structure, reliable in connection, excellent in performance and convenient to construct.

本发明公开了一种地下连续墙接头及其施工方法，通过地下连续墙接头的施工方法施工后得到，应用在地下连续墙的墙体中，墙体内设有钢筋笼，钢筋笼内填充有第一混凝土，地下连续墙接头包括：设在墙体内的止水接头板，止水接头板内设有橡胶套，橡胶套安装在止水接头板的内壁上，橡胶套内填充有第二混凝土。本发明中的地下连续墙接头，在导墙施工形成的槽内放置了钢筋笼和止水接头板后浇注混凝土以形成墙体，其中，止水接头板内形成通孔，在止水接头板内填充有带有第二混凝土的橡胶套，橡胶套紧贴着止水接头板的内壁，以密封止水接头板，从而达到止水防渗的目的，本发明中的地下连续墙接头结构合理、连接可靠、性能优良、施工方便。
