The invention discloses a fabricated underground diaphragm wall connecting node and a construction method thereof, and relates to the technical field of underground diaphragm wall connecting nodes, the fabricated underground diaphragm wall connecting node comprises a reinforcement cage, and the construction method further comprises the steps that a base is installed on the lower portion of the reinforcement cage to form a prefabricated section; the tensioning piece is clamped and embedded on a stirrup of the reinforcement cage; and the connecting node comprises a positioning structure and a pressing structure, the positioning structure is used for driving the pair of bases to move and lock the bases when the distance is fixed, the pressing structure and the positioning structure are in transmission connection, and the positioning structure extrudes the tensioning part to force the tensioning part to be unfolded after receiving transmission. According to the technical scheme, the connecting joints drive the prefabricated sections firstly, so that the adjacent prefabricated sections move to the fixed distance and are locked, the connecting stability is improved, the synchronous tensioning pieces are passively unfolded to abut against the side wall of the deep groove, the purpose of positioning the reinforcement cage is achieved, and the pouring quality is further improved.
本发明公开了一种装配式地下连续墙连接节点及其施工方法，涉及地下连续墙连接节点技术领域，包括钢筋笼，还包括：在所述钢筋笼的下部安装底座以形成预制段；涨紧件，所述涨紧件卡嵌在所述钢筋笼的箍筋上；连接节点，其包括定位结构和压紧结构，所述定位结构用于驱动一对所述底座进行位移并在固定间距时进行锁死，所述压紧结构和定位结构之间传动连接，所述定位结构接受传动后对所述涨紧件进行挤压以迫使其展开。在上述技术方案中，连接节点会首先对预制段的进行驱动，使相邻预制段移动至固定间距并锁死相邻预制段，增加连接稳定性，同步的涨紧件被动展开对深槽侧壁进行抵触，实现对钢筋笼进行定位的目的，进一步提升了浇筑质量。
